COVID-19如何改变世界？

Dec 29, 2020 Jared Diamond

洛杉矶—如今，COVID-19正在摧毁世界。它正在传染许多（甚至大多数）人，杀死一些人，切断正常的社交关系，中止大部分国际旅行，重创经济和贸易。几年后，当这场急剧爆发的危机消退后，世界会变成什么样？

一个广泛的观点是疫苗将很快就能帮助我们抵御COVID-19。可惜，前景仍然极不确定。

许多国家的科学家——中国、美国、俄罗斯、英国等——一直在竞相开发有效的COVID-19疫苗，并且第一批疫苗已经开始普及。这可能带来最坏情形，最好情形，或中间情形。

The Fourth National Climate Assessment report, 2019, said the following:
"The global atmospheric carbon dioxide (CO2) concentration has now passed 400 parts per million (ppm), a level that last occurred about 3 million years ago, when both global average temperature and sea level were significantly higher than today. Continued growth in CO2 emissions over this century and beyond would lead to an atmospheric concentration not experienced in tens to hundreds of millions of years. There is broad consensus that the further and the faster the Earth system is pushed towards warming, the greater the risk of unanticipated changes and impacts, some of which are potentially large and irreversible."
And this from the same report,
"The magnitude of climate change beyond the next few decades will depend primarily on the amount of greenhouse gases (especially carbon dioxide) emitted globally. Without major reductions in emissions, the increase in annual average global temperature relative to preindustrial times could reach 9°F (5°C) or more by the end of this century. With significant reductions in emissions, the increase in annual average global temperature could be limited to 3.6°F (2°C) or less."

-------- The National Geographic magazine published an article about discoveries fossils of palm trees that grew in Antarctica when CO2 levels were said to be at today's level. --- time to wake up.

Heroes of the Apocalypse

Slavoj Žižek

Now that Russia's war in Ukraine seems likely to continue for some time to come, Europe must accept what that means for its own long-term future. No longer do its pacifist politics or immediate economic interests offer any credible excuse for avoiding radical change.

wonders what it will take to wake up Europe in time to its new geopolitical and ecological realities.
