People will primarily move more inland within their own countries. Some cities will be raised. Neighboring countries will absorb some. Small border shifts may happen, as have happened for centuries.

You have no reason to believe this. From: https://www.esquire.com/news-politics/a25422366/trump-ambass... "The fourth and latest National Climate Assessment put together by 300 scientists from 13 agencies of the U.S. government and released last month found that climate change is real, man-made, and will cost the U.S. 10 percent of its economy by 2100. Midwestern farmers will lose 75 percent of their crop yields, and…

Wow, by 2100 it will cost the US 10% of its economy? You mean a small size recession? And you all are such a fuss about? And for that you want to deprive 3rd world people from gaining the same benefits you get from energy?

This is alarmism on the grandest scale and a horrifying hypocritical at that. There is nothing we can do about CO2 right now. We can just continue to work on safer and cleaner ways to generate electricity (atomic mainly, fusion hopefully, solar for the local homes, etc.)

If we were truly concerned, we should work on eliminating water vapor, since that accounts for much more of the greenhouse effect than carbon dioxide. Or, pump out even more carbon dioxide to increase the warming and water vapor, and hence increase cloud cover to cool the earth.

Provocatively worded... but intriguing from an engineering POV: if it is too late to limit CO2 levels and return to pre-industrial levels, what levers do we have to control water vapor levels?

Nothing. Water vapor is always in equilibrium with oceans on the timescale of weeks. In other words, any excessive water vapor you manage to put into the atmosphere will simply rain down.

After solving global warming, should we be more concerned by the approaching end of the current interglacial period? The next glacial period of the current Ice Age is going to be terrible for our stage of technology and civilization. If we are serious about the current issues of climate change, and about potential asteroid impacts, why should we not also be planning for the mid- to long-term risk of the return to an…

This is an interesting question. Haven't there been much warmer periods in our planet's history that were followed by an ice age? It is hard to sort out exactly what climate change means.

Those warming periods are either local, are much, much slower and they are not supposed to be in sync with human activities either.

This one is much faster. Not everyone sees it of course. Change blindness is what they call it.

The problem with many discussions around global warming is not scientific, but cultural. Advocates of change often take a sanctimonious attitude toward anyone expressing the slightest doubt. Have a look at the episodes of the Netflix series "Bill Nye Saves the World" on climate change. If you can watch without cringing, congratulations. I can't. Or take this interview Nye did with Tucker Carlsen: https://www.youtube.…

Challenge accepted. Proof that humans are responsible for rising planet temperatures: https://climate.nasa.gov/evidence/. Follow the references.

"every hypothesis should be questioned."

It is, constantly, literally on a daily basis. That's how we know.

What does pop culture (Bill Nye) has anything to do with this.

Also many of us are a bit beyond just theoretical discussions. It's 2018. We are increasingly affected by climate change to the point that many of us are packing, because the shit already hit the fan. What's a fun theoretical discussion for you (at the moment) is actually life and death for many.

If this was 1980, then I'd be right with you. But it's 2018. We've had 40 years of unmistakable data, and at this point, anyone pushing this "the science isn't settled" talking point – adopted from the tobacco industry – either has a vested interest in denialism or simply falls really far left on the Dunning-Kruger curve.

Indeed it's 2018. The shit already hit the fan. We suffer unsustainable ecosystem losses on a daily basis.

Climate discussion now seems to come from Yes, Prime Minister. (1986). We appear to be at stage 3. I don't understand US politics.. Most UK voters, of both political sides, agree there is an issue, and want constructive solutions[0]. Some more US-like differences at the margins, and differences in urgency, but there appears to be a broad consensus among the public. Less so amongst politicians themselves. Does politic…

In the U.S. and apparently also in Australia, it's all politicized by the right wing climate science deniers, who have swallowed petrol industry propaganda, who view the embrace of basic science by anyone, regardless of their actual place on the political spectrum, as an Obama/Clinton/"libtard" hoax aimed at taxing their precious wallets and taking away their freedom. You can see it in the comments here denying climate science and making false claims about the existence of "many scientists" who disagree with the consensus and think there are other causes of climate change, ignorant nonsense about coming ice ages, and so on.

There are many scientists that believe solar forcing is responsible for temperature increases on Earth, Mars, Triton, Jupiter, and Pluto. While CO2 promoters point out the fact that solar irradiance changes are relatively small over time, they ignore that those same irradiance changes correspond to changes in solar magnetism, which means changes in cosmic ray incidence on planetary atmospheres. It is well known that…

"There are many scientists that believe solar forcing is responsible" The solar constant in the past 400 years has varied less than 0.2 percent. "It is well known that cosmic rays effect cloud formation." Not well known, because the research is still ongoing. Henrik Svensmark's research in a dust- and impurity-free atmosphere contributed to our understanding of aerosol microphysics, but others agree that the effect i…

From your quoted article.

    This work offers a new understanding of global particle 
    formation as based almost entirely on ternary rather than 
    binary nucleation, with ions playing a major but subdominant 
    role. Our results suggest that about 43% of cloud-forming 
    aerosol particles in the present-day atmosphere originate 
    from nucleation
This is a major effect, confirmed by your own article. I'm not certain why you linked it, since you are arguing against cosmic rays effecting cloud formation.

it really is.

I'm not certain how to respond to such a non-argument in such a biased forum as this one. I would respectfully just point out that on this subject, you are in a filter bubble, which you obviously have made no attempt to escape from.

Alarmism was never so appropriate. We have so much to lose.

The predicted costs of tackling it are significantly lower, so why not just tackle it and avoid the recession.

Also, a permanent loss of 10% is not a small recession, most recessions lead to no permanent loss, just a demand shock which is made up afterwards. A permanent loss of 10% is more like the financial crisis, and I’d rather avoid that if I can. One brought Trump and Brexit, I’d rather not add another to the mix.
