Is the planet on track to limit the post-2015 increase in global average temperature to 1.5°C as set in the 2015 Paris Accord?
a. Yes
b. No
And the answer is …
The answer is No. The latest estimate is a 2.7°C (4.9°F) rise in global tempearture by 2100. Here’s the general view of the impact of such a temperature rise as summarized by Google’s AI search engine: A 2.7°C increase in global temperature could place a third of the world's population outside the "climate niche" suitable for human habitation. In short, stabilizing global carbon emissions, as appears may be happening, is far from sufficient to prevent a climate catastrophe. For what, in my view, is the best model of optimal carbon tax policy, see this study, forthcoming in The European Economic Review.
Which country is larger, the U.S. or China?
a. The U.S. is much larger
b. China is much larger
c. The two countries are roughly the same size
And the answer is …
The two countries have essentially the same land mass, with China’s slightly larger. Interestingly, the U.S. has more farmland thanks to moisture from the Gulf of Mexico preventing the midwest, including Minnesota, from desertification. Yet China has more agricultural output than does the U.S.
Interesting post! Thank you.
