There is unequivocal evidence that Earth is warming (2024) (science.nasa.gov)
legitster 1 days ago [-]
Even the crotchetiest and most out-of-touch people I know basically accept that the Earth is warming now. They just either disagree on the cause or proportion.

Some people just naturally resist hyperbole or sensationalist rhetoric, and I find it very helpful to reframe the argument from doom and gloom and fire and brimstone to something more realistic and grounded:

"The longer we put off doing something, the harder and more expensive it will be in the future. In a Pascal's Wager sort of way, many of the changes we are talking about don't even really cost us anything, and the potential that C02 is not a real culprit is more than made up by danger that it is. Making changes now is the prudent and financially sound decision."

In a large part, this is what the brief ESG trend on the stock market was briefly about before it got co-opted by a dozen different competing messages.

The problem with Pascal's wager logic is you have to change your behavior based on all kinds of crazy low-probability events. You must worship every god, be an AI-doomer, a climate-doomer, a nuclear-doomer.

Pascal's wager is generally agreed to be logically unsound, so it's somewhat insane that we've revived it in all these modern contexts. If you believe in it, at least be consistent and sacrifice a goat to Zeus every couple years.

pablomalo 14 hours ago [-]
Pascal's wager, as it relates to faith, is based on the premise that there is a lot to win in making the wager --but little to lose. In turn, that second part is grounded in the assumption (right or wrong, I won't judge) that living according to Christian principles brings benefits _in this life also_ to the individual who so chooses.

So it seems a mischaracterization to present the essence of the wager as going out of your way to perform random and costly rites in the hope of lifting any ill omen.

Exactly. For example, what if making such wagers is key in determining that you belong in "hell" for not being genuine?

Here’s a video called “Is AI safety a Pascal’s Mugging?”: https://youtu.be/JRuNA2eK7w0

I haven’t watched it back but from what I remember the main point of the video is that kind of situation happens when the probability involved is vanishingly small, and all the events you listed don’t have a vanishingly small probability, so they are not Pascal’s wager situations, just a normal rational safety concerns with particularly high consequences

legitster 1 days ago [-]
Yes, and no. I think we actually do this logic a lot in our lives. Do I actually believe whole wheat bread is better for me, or do I just buy it on the chance it is? Do I go with the cheapest toothpaste or spend money on something that might be better? Do I buy an AWD car on the chance I am stuck?

Sacrificing a goat, after all, does sound like a lot of work. But maybe I will wear a lucky hat to a baseball game?

In this case, it's not exactly like Pascal's wager because there is plenty of scientific evidence of disastrous consequences of not believing in climate change (and preparing accordingly). There's no evidence to suggest that a non-belief in God will send you to hell.

POTUS tweeted "WHATEVER HAPPENED TO GLOBAL WARMING???" a few weeks ago when a record cold wave came in. I suppose you were talking about people you personally know, but it seems like there's a good chance many who voted for him would say it too.

Anyway, I guess there is a growing collective admission that the climate is changing even if the crotchety ones will still quip about it not being warmer at some given time and place. It's unfortunate that "global warming" caught on instead of "climate change."

Except it's the opposite - empirical evidence is very easy to ignore. Between herding, the replication crisis, and the overall insularity of academia, trust in "studies" has never been lower.

But people still respond very well to demonstrative or pragmatic evidence. Empirically there's nothing special about a keto diet. But demonstratively the effects are very convincing.

At the top level (of government and corporate entities) those people always knew it was real, the messaging just changed as it became harder to keep a straight face while parroting the previous message in the face of overwhelming empirical evidence.

Exxon's (internal) research in the 1970s has been very accurate to the observed reality since then.

They just didn't care that it was real because they valued profits/power/etc in the moment over some difficult to quantify (but certainly not good) future calamity.

You would think they would care at least in the cases where they had children and grandchildren who will someday have to really reckon with the outcome, but you'd be wrong, they (still) don't give a shit.

I'm a different kind of crotchety.

I think it's real and potentially catastrophic. But I see very little chance of (sufficient) coordinated action to mitigate it.

I.e., I think there's too much temptation for individual countries to pursue a competitive economic or military advantage by letting everyone but themselves make sacrifices.

I hope I'm wrong.

For developing countries, having a large supply of fossil fuels has always been a huge accelerator for industrialization and overall economic growth even if that fuel has to be imported.

My family is fundamentalist protestant, very midwestern, and I think about half of them believe that the earth is warming. Not trying to "win", just trying to say that a lot of this depends on the crowd you interact with. I don't know the percentage, but certainly there are still way too many people that don't even believe it. The very tired response is "well i wish it would warm up here slaps knee". Using the phrase 'Climate Change' at least reduces that objection.

My father in law was a massive climate change denier until some trees started dying on his property.

He called out an arborist, and the arborist clearly explained that there wasn't enough rain anymore to support the number of trees on his land, and that the forest was slowly receding as the older/bigger trees took all the water from the other trees.

It finally dawned on him that a place where trees used to happily live to hundreds of years old could no longer support trees.

Still, he thinks CO2 is a con job cooked up by China and that global warming is divine punishment. But it's a good reminder that a lot of denialists are waiting for a personal, practical reason to care.

"Climate Change" implies that some sort of "constant climate" is even attainable, irrespective of desirable.
mithr 1 days ago [-]
It doesn't; that's kind of a first-glance reading of the phrase without really thinking about it.

Something can said to change from a certain standard even if it wasn't perfectly constant to begin with. For example, if I always kept my house at 65-75 degrees for the past year, and now it's 85 degrees inside, I could certainly say that the temperature in my house recently changed and gotten warmer. That might lead me to check whether my AC's working, rather than say "well I guess the temperature has never really been constant, and 85 is within the range of possible non-constant temperatures, so everything's perfectly normal and nothing has changed."

alt227 1 days ago [-]
Your analogy doesnt work, becaue the earth has been warmer than it is now several times in the past. so the increased temperature is within the range of normal temperatures.

The problem is not that the earth is warming, it is that it is warming at an artificially increased rate.

larkost 23 hours ago [-]
The rate of warming is a problem (i.e.: it determines what generations of humans are going to see this), but the major problem is the warming itself, or rather the change.

We (humanity) have gotten comfortable with the way things are, and a change in that is going to mean that things are going to change for us, and we don't like change. Most of our biggest cities are all close to the coast and will be subject to massive flooding in the next 100 years (if not sooner). Much of those same large population centers are also fairly close to being too hot for general survival (without aggressive AC). Our agriculture is all setup for the temperatures we have now, and the rain patterns we are used to. So we are going to have to change both where we live, and how we grow our food (location and probably strains as well).

Global warming is (almost) definitely not going to destroy all life on earth, but many of the forecasts are in extinction-level for most of the large animals. So life in general will continue, and probably humanity (since we are so good at making environment for ourselves), but the (eventual) changes are going to make the world very different, in ways that we are not going to like.

alt227 4 hours ago [-]
The warming is definitely not the problem (for the earth itself), only for the human race of which I care very little for.

Many different groups of large animals have lived and died off over the ages. It will happen again many times after humans are gone.

Only with an excessively literal interpretation.

If I pick up your house and drop it two streets over, that could be accurately described as a "location change" of your house. This is still true despite the fact that your house naturally moves some centimeters per year due to tectonic plates shifting around.

Similarly, when global average temperatures saw long term trends of a fraction of a degree of change per millennium, then suddenly started changing at multiple degrees per century, it's pretty reasonable to call that "climate change" despite the fact that it was not completely constant before.

This is the part that seems to vary widely based on which warming alarmist you're talking to. Many of them are not saying there are things we could do that "don't even really cost us anything" that would deal with the problem--they're saying we need to devote a significant fraction of global GDP to CO2 mitigation.

Things that "don't really cost us anything" are probably happening already anyway, because, well, they don't really cost us anything.

Building a lot more nuclear power plants is the key thing that doesn't really seem to be happening right now, that would be an obvious way to eliminate a lot of CO2 emissions. But of course that does really cost us something. But it's probably the most cost effective thing we could do on a large scale.

nradov 1 days ago [-]
Among the large set of people who think we should take steps to reduce anthropogenic global warming there are at least two subsets who seem to oppose nuclear power. One is sort of pseudo-religious and believes that any disruption of the natural environment is a "sin" against Mother Nature. The other claims that nuclear power is too expensive and that we can solve the base load power problem more cheaply with battery storage, despite the lack of evidence that we'll be able to scale it up fast enough in the time available. And I have nothing against building more battery storage where it makes sense, but I don't think that's going to be sufficient by itself.
bryanlarsen 6 hours ago [-]
It's not a base load problem, it's an intermittency problem. Which you solve with dispatchable generation. Which nuclear is particularly ill suited for.

> in the time available.

Which also eliminates nuclear as an option; Ontario is building new nuclear power that is projected to become available in the late 2040's. After the inevitable delays that'll be the 2050's. Way too late.

The solution is simple & cheap, though nobody wants to admit it. Use paid-for existing zero-carbon generation first (aka existing nuclear, hydro, etc), then add solar & wind to cover ~60% of needs, then add batteries to cover ~95% of needs, and then use natgas peakers to cover the last ~5%.

Environmentalists don't like it because it's not 100% carbon free. Anti-environmentalists don't like it because it's 95% solar/wind/batteries.

Economists and pragmatists should love it because it's the cheapest.

legitster 1 days ago [-]
> Building a lot more nuclear power plants is the key thing that doesn't really seem to be happening right now

I mean, this is the clear and obvious one. Nuclear theoretically should be much, much cheaper than it is if it were not for the regulatory costs thrust upon it.

It also harrows out people who are legitimately concerned from "moralist concern junkies". You'd think climate change being a global existential crisis would make people open to nuclear energy or more drastic measures like geo-engineering, but the frequency with which people refuse to compromise undercuts the their legitimacy.

You can do a thought experiment. A nuclear plant and a coal generator are very similar. They heat water to turn turbines to generate electricity. So best case scenario a nuclear plant costs the same as a coal plant, and has negligible operating costs in comparison.

A coal plant costs $5B/GW to build, vs the > $20B/GW a nuclear plant costs.

Those massive turbines are really expensive.

OTOH solar + batteries is well under $1B / GW.

cosmic_cheese 1 days ago [-]
Another reframing that may be useful is energy security/redundancy.

If you have a cheap source of solar panels and batteries, the only downside to installing them all over the country is up-front cost (which pays itself off quickly). The upside you gain is a substantially more robust, less centralized power grid that can continue to operate if something happens to impede your supply of fossil fuels or part of the grid gets cut off.

Looking at how things have played out elsewhere in the world the past few years, that's powerful.

  Across the world, according to BNEF, the cost of grid scale battery packs has fallen another 45 per cent in 2025 following a 40 per cent fall in 2024. The UK-based energy think tank Ember has now also reached the same conclusion, underlying its unexpected impact on solar power.
from: https://reneweconomy.com.au/the-plunging-cost-of-battery-sto...

citing: https://ember-energy.org/latest-insights/global-electricity-... and similar reports.

Resource prices for batteries did spike at various times in the past, this had more to do with opening and then closing a lot of production sites by mining companies than with any real meaningful supply issue.

Urban grid scal battery parks are on the rise globally, industrial parks have always had special status and can still concentrate modern efficient peaker turbines and buffer storage to bridge, if applicable, and use any general daytime excess.

Rising from an extremely low baseline. Actual deployed grid scale battery storage worldwide remains minuscule in relation to daily electricity consumption. Sure let's deploy it where we can but it's delusional to believe that this represents a realistic alternative to nuclear or fossil fuel power for industrial base load requirements in most countries anytime soon.

I hear that often, but it's never followed by details about any of the actual changes that are being talked about. The ones I actually hear (especially politicians) advocate for are catastrophically expensive and dubious in their effectiveness. Banning coal or gas-powered cards might (might) be a good idea in the long run, but it definitely does cost us something.

wat10000 1 days ago [-]
Banning coal is a complete no-brainer at this point. Has been for quite a while. Never mind climate change, it's horribly polluting. The only reason it's still remotely economically viable is because the people who burn coal don't bear the costs of their pollution. If they actually had to compensate people for all the cancer, lung disease, poisoned ground water, contaminated seafood, and other such problems they cause, coal would vanish.

It's already to the point where the ridiculous coal fans who infest our government are forcing coal power plants to remain open when their operators want to close them because they're no longer profitable to operate.

banning coal is quite cheap even ignoring the emissions and pollution side effects.

You need to understand the political and cultural history. Environmentalism has been associated with leftist, feminist and communist ideology going back to the hippies and the antiwar movement (which makes it easy for many Americans to mistrust by default.) When Trump said he believed global warming was a Chinese hoax (remember that?) he was echoing a belief amongst the right that environmentalism and "global warming" was a plot to undermine American business and sovereignty, and that climate science supporting anthropogenic climate change was manufactured by "cultural Marxist academics" to push that agenda.

This conspiracy thinking has been pushed by Republicans, right-wing think tanks, coal, oil, manufacturing and like industries attempting to undermine public trust in climate science since at least the 1970s.

And for very specific reasons, too.

One reason is unwillingness to feel like they have to take responsibility.

Another is conceding that would mean they might have to make changes, and laziness is powerful.

The worst reason is that to acknowledge it would be to grant that an alternative political perspective is right about something, and one's own political identity is tied to that other political perspective being always wrong.

"It is easier to con a man than to convince him he has been conned." Too much emotional investment in being right and too much fear of social repercussions simply for changing one's mind. The reality is changing one's mind to new data is the hallmark of integrity.

What is generally not understood is that our current icehouse phase is rare.

'A "greenhouse Earth" is a period during which no continental glaciers exist anywhere on the planet... Earth has been in a greenhouse state for about 85% of its history.

'Earth is now in an icehouse state, and ice sheets are present in both poles simultaneously... Earth's current icehouse state is known as the Quaternary Ice Age and began approximately 2.58 million years ago.'

Modern humans have existed for 60k years, all of which have been in this current icehouse.

To cast a different shade on the meaning, this climate period is rare, easily disturbed, and difficult to restore even with vastly more powerful technology. The more common greenhouse state is unlikely to lead to a Venus runaway, but it will be hostile to us.

We might very well require the rare climate, and perish in the common.

Previous climate changes happened over tens of thousands of years. This one is happening in decades.

It's the speed, not the magnitude that matters. Change faster than evolution and migration will destroy ecosystems.

Yeah, I wonder how fast Chicxulub affected the earth when the majority of large dinosaurs were wiped out.

The earth survived and evolved another set of new large animal masters. The beauty and diversity of nature we see around us has all evolved after several extinction level events which have all very rapidly killed ecosystems and changed the earths climate.

It will do the same again after all humans are gone. This is the outcome I am hoping comes sooner rather than later.

This only really matters if you think humans are really important and should exist forever no matter what.

I personally think that humans are a blot on the earths history, and soon should be wiped out to let nature and evolution retake its course. From this perspective we are just following the natural course of the earth, and will be made extinct just like other various groups of large animals on this planet in the past.

We may require the rare climate, but other species certainly dont and more will evolve to take the place of humans when we cannot survive on these planets conditions any longer.

One of the challenges in doing something about climate change is the significant (and not entirely unfounded) distrust growing between the public and the government.

Basically amounting to, "well, you say you're doing X to combat climate change, but is X actually a competent solution (I don't trust your competence), and are you doing it to actually help or just to line pockets (I don't trust your intent)".

The other challenge is that we as individual humans are loathe to give up our comfortable lifestyle if such turns out to be necessary.

I am fortunate to have lived on the water for over 20 years in a location, East Coast USA Chesapeake Bay, that has scientifically documented many aspects of the climate changes that my own eyes have witnessed and photographed here at my home. I can walk out in my back yard and see these changes in this moment of time as they now exist and all of these changes have only become visible to me here in the last 10 years.

Erosion is a significant aspect of what I have witnessed however the ying always has a yang. Just as significant archeological discoveries are being made around melting glaciers so too are such discoveries also being made along eroding shorelines. The known history of the Chesapeake Bay is extensive and the items washing out of its shoreline are too, both known and unknown. Many of the paleolithic/native artifacts I have found can be explained by experts while some I have discovered cannot.

Change is the only thing guaranteed in this life until your life too forces change at its end. Change requires change and that means you but as a species we are wired into our daily pattern and nearly all hate forced change. As the old saying goes: "Nothing stays the same forever."

Future humans (if we survive) will look back at climate denialists (or who agree it exists but don't want to do anything about it or refuse to believe it's accelerated by CO2 emissions or burning fossil fuels), the same way we look back at the Catholic Church during the inquisition era who stupidly refused to accept a heliocentric world (and imprisoned and sometimes burned at the stake those who did).

Except that today's denialists, and the politicians/governments who enact their policies, are much much stupider, and dangerously so, because 1) we have much more evidence than the Church had, and 2) while there was relatively little harm in believing the Earth was the center of the solar system, there is great harm in believing that burning more fossil fuels doesn't accelerate global warming.

I wonder if we should move beyond this messaging. It’s well known to the smart half of the population that climate change is happening. There is apparently some debate on the cause. But this point is mostly irrelevant, it is problem-oriented thinking. By keeping the conversation in the problem-realm you invite troglodytes into the conversation to insert their bullshit. Instead, if we move forward with “presumption of truth” solutions-based messaging, we can start to talk about what we’re going to do.

The answer has never laid in ever more elaborate designs to disenfranchise particular members of the population. It's always been in building community.

A community is what helps stabilize, helps tighten up distributions, and wrestles most authentically with the general premise that we are social creatures and only as strong as our weakest link.

I basically see it as a moral wrong and a grave ethical failure to use fossil fuels at this point. Except for home heating, I am now close to directly powering my entire life with clean, renewable energy. It was not hard. It was expensive, but only in the short term; I have effectively prepaid for my power needs for at least the next 25 years, and over than span it is very inexpensive.

A modern EV is about the same price as any other car, goes about the same distance, and is only slightly more time to fuel in the worst case. In the typical case, you don’t think about charging at all. The fact that I can’t get my supposedly environmentally conscious family of scientists and engineers to care continues to stun me. Somehow saving money while improving the world is “a waste of money” while buying an expensive hobby vehicle or vacation home is not. Frustrating.

I agree that human extinction is very unlikely on anything like historical timespans. Maybe in a few million years, like any other species.

I do think there's a decent chance of civilizational collapse in the near to medium term. It seems like everything is getting very fragile. So much economic activity revolves around extremely sophisticated machines with many critical components that are manufactured in just a few locations, sometimes a single location. A major war could shatter that, or climate change could push us over a tipping point where those capabilities can no longer be maintained, or it might just be a cascading random breakdown due to the modern economy being so complicated.

If it happens, then I'm very pessimistic about the ability to ever come back from it. With all the easily accessible fossil fuels gone, getting industry going again is going to be a really tall order. So humanity might survive a long time, but it may consist of life the way it was in prehistory.

> My impression is that almost no one denies the warming itself, just the link to greenhouse gasses. That link is unfortunately much harder to prove than rising temperatures by itself.

The link to greenhouse gases is not hard to prove. We've got satellites that can measure global radiation inflow and outflow and see what the difference is. We can also measure this at various levels within the atmosphere, and at the surface of the land and oceans. We can see where outgoing radiation is getting caught and we can see what frequency bands of outgoing radiation is getting caught.

We know the frequency bands that get reflected, absorbed, or pass through for all the gases in the atmosphere and can see that the gases causing the problem are the greenhouse gases.

We can also see that the increase in greenhouse gases is mostly from burning fossil fuels. We can see this by looking at the isotope ratios in the C in greenhouse gases.

Cosmic ray bombardment in the upper atmosphere produces carbon 14, which is radioactive with a half live of 5730 years. It disperses throughout the atmosphere and becomes part of anything that regularly incorporates atmospheric carbon or exchanges its carbon with atmospheric carbon, including all living things.

Everything humans do in significant amounts that puts greenhouse gases in the atmosphere other than burning fossil fuels has carbon with about the same isotope ratio as that of the carbon in living things. Even when we burn a dead forest to clear it out the isotope ratio is close to that of living things, because of that 5730 year half life for carbon 14.

It is only when we burn fossil fuels that we put carbon into the atmosphere with almost no carbon 14. They came from living things but have been dead long enough for hundreds of half lives to pass.

The isotope ratios in the excess greenhouse gases show that it is mostly carbon 14 free. There are natural processes that can dump carbon 14 free carbon into the atmosphere such as volcanoes and other geological processes. However, (1) the increases in carbon 14 free greenhouse gases matches very closely with the amount of carbon we've been emitting from fossil fuels, and (2) and monitoring of volcanoes and other natural sources doesn't find nearly enough to account for more than a small amount of the increase.

I fall in that category. My suspicion is that water vapor from air travel is by far the biggest contributor. I saw the blue skys after 9/11. I read the NASA guys that said daily temperature range increased measurably. I saw the blue skys again during Covid19.

I'm also of the opinion that anyone looking at historical data only going back 200,000 years or less is missing the larger picture. Sea levels are NOT at historic highs, we should expect them to rise further before receeding. We should expect glaciation again if we don't do anything, but speeding up warming IMHO is more likely to trigger glaciation that to "push through" whatever causes it and break the cycle (which would be a good thing).

So as a long-term thinker all this hype is just that. If you don't have a plan to end the glacier cycle you're just making a big deal out of a small change in time-scale due to reasons (CO2 vs H2O) that may well be the wrong ones.

Clouds reflect radiant heat back into space. Contrary to your claim, "global dimming" was a very active research space for a long time, and in fact the water vapour and other airborne pollutants likely masked the impact of global warming.

I think many people are unwilling to accept "climate change" or "global warming" because of the following:

a) china is unwilling to do anything, and if that's the case, America shouldn't empty its pocket books on this issue.

b) this climate change alarmist stuff has caused a climate disaster in the US because all the migration to Electric Only is causing us to use generators all over the place, which is crazy. We should instead focus on making clean nuclear and expanding solar. PG&E (in CA) has decided to cancel this migration because CPUC (or whatever their called) is in Newsome's pocket who is in PG&Es pocket.

c) climate change extremists are unwilling to both hear yes it's happening and no we're not going to do anything about it, so the people responding are simply saying, no it's not happening.

China is massively building solar, wind, hydro, and nuclear, and also has by far the largest network of UHV transmission lines (and are building many more) so that they can get electricity from the regions with the most solar and wind to the more northern heavy industrial areas.

They are also the leader in producing and exporting solar and wind equipment, and in driving the prices down, to make it easier for other countries to address climate change.

They are also the biggest producer of EVs in the world, and the biggest exporter of EVs.

They are doing better at doing something about climate change than any other country, both due to what they are currently doing for themselves and for the countries they export to and in their ability to make long term plans and reasonably stick to them.

The US can't even get countries to enter trade agreements anymore, because it's throwing around threats of large tariffs and annexation of others' lands. The world could drop the dollar as the reserve currency, something that was gradually happening but is now accelerating.

If the US starts trying to force other countries into climate action without taking into account its own contributions, the US will likely cut out of the global economy, and become far poorer as the rest of the world surpasses its wealth through vigorous trade.

The US was the sole remaining superpower, but has recently decided to only occupy a much weaker position with a mere "sphere of influence" and ceding leadership in other parts of the world to others. The US is signalling to allies in Europe that it will no longer lead, that the prior world is over and the US is bugging out, meaning Europe will gain far more influence.

The more that the US attacks others without providing any leadership, the less that the US will be able to take from the world. Up until recently, the US's position of massive economic strength was largely due to it's dominant position among nations and the goodwill that others had towards it. Turning the climate problem into a blame game on other countries would further weaken the US's position and options.

The US defines the terms of the vast majority of global trade agreements and there’s no indication that will ever change.

Trump in his first term gave the Pacific over to China, who now defines terms over there. In his second term, Trump is cutting the US out of leadership in Europe, leading to growing economic trade agreements that exclude the US.

You seem to think these solid critiques about the inherent weakness of Trump are somehow mere partisanship, rather than the actual unwinding of US leadership around the world.

I'm not part of global academia, I'm just a consumer of news that is willing to listen to things outside of a partisan bubble. The world is shifting away from the US, to the US's detriment. We have an exceptionally weak president who acts like what a weak person imagines a strong person is like, and it's scaring off all our allies.

If you think the world is shifting away from the United States, or that Trump isn’t having his way with virtually every trading partner on the map, then it seems you are falling victim to strong anti-US rhetoric. This rhetoric isn’t based in reality. The US leads the defense strategy of the entirety of Europe, and Europe has no other alternative. There may be some politicians that want to choose the US as “the loser”. But that’s just not really an option given the size of our economy and the size of our military.

TDS inspires people to blurt out the types of statements you’re making.

epistasis 6 hours ago [-]
You throw around insults like "TDS," and try to say that a plain and calm stating of facts is "blurting," but is there even a single trading partner where Trump is having his way? He makes ridiculous demands, throws around tariffs, and at most he extracts a memorandum of understanding that maybe there will be a trade deal in the future. Trump promised something like 100 new trade deals last year in a matter of months, and long after the deadline where are the deals?

The clear facts are that the US has cheapened its word and made itself an embarrassment around the globe. China has completely dog walked Trump on tariffs and trade, devastating US farmers, and leading to far stronger ties between China and the rest of the world, not just with our former tight trading partner Canada, but with all the emerging economies around the world. The US is cutting itself out of the new economic order that is emerging from the energy transition to cheaper renewable energy, which will leave the US with sky-high energy prices while the rest of the world runs their economies cheaper, and with less inflation-inducing price shocks, on solar and grid storage.

I respond with these basic facts not because I think that you will believe anything, but because the obvious falsehoods that you are repeating should not stand unanswered by the reality that we can all see in the world.

> There may be some politicians that want to choose the US as “the loser”. But that’s just not really an option given the size of our economy and the size of our military.

The only politicians that wants to choose the US as the loser are those following the dictates of Trump, by weakening our gloabl position. The size of our economy and military are not enough of a draw to keep us as the leader through sheer domination. And in fact pretending that "domination" is what made the US strong is the exact sort of weak person's idea of a strong man. The US is handing away all its leadership and power by trying to force what it does not have the ability to force, trying to force what would instead be freely given! It's utter insane behavior of a nation, and indicates just how little the Trump administration understands of US power around the world. The US is not a mob boss, we are (were?) a leader that attracted support because we were a shining example of what a country could be. When we act like bullies we throw away all that power, because we can not fight the entire world with our military, and our economy is not nearly big enough to overcome bullying behavior.

Edit: an as for an example just this morning of how Trump is making the US weaker, the UK is not allowing the US to use bases for attacks on Iran, which is leading to other threats from Trump that further push the UK away and make the US weaker on the global stage. Nearly every single day the US is becoming weaker because of this sort of weak behavior. https://www.thetimes.com/uk/politics/article/trump-chagos-is...

Why should should per-capita be most important?

Because per capita is the only thing that makes sense.

If China were to split into 10 countries each emitting 10% of what they do now it'd be the exact same emissions, but according to you it would be much better.

Similarly if the EU would become one country, that country would be high up on the list, much higher than member countries now! Oh no!

Emulate them?

PRC solar power production last year conservatively will diplace ~45 billion barrels of oil, or 10%-20% more than total global consumption per year. It's just retarded eco accounting that attributes emissions to renewable manufacturers while fossil exporters don't get any penalties for extracting emissions.

Every year of PRC solar prevents doubling of oil, basically they're like the only significant country whose net contribution is negative for how much carbon sinks they manufacture. So the answer for US+co is obviously stop exporting oil and lng, and start exporting renewables.

Actually climate is determined by cumulative CO2 emitted. The US and Europe have emitted far more than China ever has.

As of today, solar and batteries are the cheapest source of electricity. All the "poor countries in Asia and Africa", except the ones that have oil and gas, will leapfrog straight to renewables. It just makes good sense, unless your politicians are paid off by the fossil fuel lobby.

The evidence isn’t that complicated.

Windchaser 1 days ago [-]
I know you're getting dogpiled, but global warming has been validated, not debunked.

The science behind it really got going in the 1890s, with Arrhenius' paper predicting climate sensitivity to CO2. That was bounced back and forth with rebuttals and counter-rebuttals until about 1950. Major debate points were how much role water vapor played, how this varied with temperature/altitude/pressure. (You can trace each part of the argument if you're so inclined; there's lots of neat science in there. The concept of "pressure broadening" was my favorite; it explores how spectral bands change with pressure).

Around 1950, the science started settling out. Spectrometers had improved, we had clearer view that CO2 and H2O don't fully overlap in their spectra bands through the atmosphere, and we had the computing to do better calculations. By the 1970s, we were getting ice core data showing that the world had gone through huge temperature swings, and how this changed with CO2. Enough data had accumulated that a consensus was forming. In the 1980s, scientists were now concerned enough to form a large body to inform policymakers on this issue (IPCC; 1988). And in the 40 years since then, we've mostly sat on our hands, even as the science just gets clearer and clearer.

I share all this long history to explain that the science went through nearly a century of rigorous debate even before politicians got involved. This a scientific issue, not a political one. And I'm glossing over 99.9999% of the detail here. There was an extensive literature debate between the scientists, hashing out any point you can think of. You just have to go to your local uni library and start reading.

TL;DR: saying that global warming is debunked is about as incorrect as saying that the Earth is flat. We have extensive evidence showing otherwise.

I agree it's warming but unequivocally at an unprecedented rate is iffy. For the article they cherry picked a stable period but if you look at the full temperature history as shown here https://statmodeling.stat.columbia.edu/2014/05/05/can-make-b...

there has been loads of instability and heating and cooling.

Also while CO2 levels are up from about 280 ppm in 1600 to about 430 now, for most of the history of life on earth they were more in the 500 to 5000 range https://en.wikipedia.org/wiki/Carbon_dioxide_in_the_atmosphe...

I don't believe climate denial as in saying its not warming but I'm also skeptical of exaggerating the problem by ignoring most climate history. I guess the idea is to panic people into changing behaviour but it doesn't seem to work very well - co2 emissions are higher than ever and a lot of the population think we are doomed when we are not. Unbiased science is better in my opinion.

Windchaser 4 hours ago [-]
There's some truth to what they're saying.

Simply on a factual basis, the data we have from previous extinction events does not have the temporal resolution needed for us to determine how quickly the temperature increased/decreased. E.g., "how quickly did the atmospheric temperature change after the Chicxulub event?" We don't know. Decent-quality global paleoclimate proxies only extend back ~15k years or so. It's possible that there was rapid global climate change in the past outside of major extinction events; we genuinely don't have the data to tell.

This also doesn't really tell us much about how the modern Earth and its ecosystems would handle those old climate shifts, because there is much much less wild lands (and so, less resilience within natural ecosystems). It's true from a climate science perspective, but not useful for assessing the damage that climate change can cause to modern society.

And: to the best of our knowledge, the current rate of warming is fast enough to cause major issues. Civilization only arose once we had relatively stable and moderate temperatures, and stable temperatures may be needed to maintain civilization under present technology. Ecological and glaciological studies back this up. And no, scientists are not looking to just scare us into action; the evidence itself should be alarming.
