I'd argue we have no idea what will happen when the glaciers melt, given the lack of accurate climate change predictions to date. We have a lot of models that have historically proven very incomplete with no reason to believe they're any more complete now. The oceans rising is more a problem, but it's not going to end human civilization and will happen slowly enough that adaptation is possible, albeit expensive. "Dro…

Oh my Sweet Summer Child, you really have an unplaced faith in humanity - especially given our track record. "The sky is shifting" - is a hand-wave to the life-changing impacts headed our way and what our collective response to those impacts will be. Look how nuts people are getting over what are mere trivialities in comparison. Wait until there's crop failures threatening our food supply, fresh water supplies being…

So is understating the impact. This take is seriously dangerous. "1.5C is not so bad, chill people" When the fact is - we don't know the impact - if we go beyond 1.5. What we do know (because it's already very much measurable) is that much of the worlds glaciers will melt, causing drought. What we do know is that eventually the sea levels will rise and drown many extremely valuable coastal areas.

we don't know the impact To your point, we know quite a bit, and it's pretty bad. Will 10% of the world's population perish? Most likely. There's already a population die-off in progress in many areas of the world as the birth rate continues to decline. People don't have to drop dead for the population to die off, they can simply not be born in sufficient numbers to replace the existing population. As for those who a…

What I always find so hard to believe is that, knowing how well we can predict weather and other complicated systems, climate change science somehow is able to make 1/10 centigrade precision predictions on time horizons of decades and centuries.

If climate models were predicting the temperature of your city on March 21, 2120 then your intuition here would be wise. But that is not at all what these models are predicting. They are predicting global average annual temperatures and other gross, planet-scale statistics. "Average annual global temperature in a given year" and "temperature in my city tomorrow" are fundamentally very different types of predictions.…

So, does this apply to China, which is burning more coal than ever? The UN secretary general, António Guterres, said: “This report is a clarion call to massively fast-track climate efforts by every country and every sector and on every timeframe. Our world needs climate action on all fronts: everything, everywhere, all at once.”

This is not one of those problems that goes away by pointing a finger.
