The effects of excess CO2 (climate change, sea level rise, coral bleaching, ice melt etc etc etc) and so well linked and demonstrated that I can't believe we're still having this debate.
Now: Asia produce, Europe and Asia gain
Cince 1990 emissions dropped 4 times
"The best time to plant a tree was 20 years ago. The second best time is now."
"The biggest absolute emissions come from China and the United States. In terms of CO2 emissions per capita, China is ranked only ranked 47th, at 7.5 metric tonnes per capita. The US is ranked 11th at 16.5 per capita and amongst countries with sizeable populations, has the highest CO2 emissions per capita. India is the third highest country in terms of absolute emissions, but only 158th in terms of per capita output with 1.7 metric tonnes per capita."
So thinking about China or India, right now still pretty low in the per-capita-ranks, continuing their speedy economic growth, is kind of worrying. On the other hand, looking at the US as the worst polluter per capita and comparing them to the likes of UK, there is huge room for improvement.
I'm not completely optimistic about the outlook right now, but I'm becoming more hopeful for what the coming decade can accomplish. It seems that developed and developing countries alike are becoming serious about capping CO2 emissions and investing in clean energy. Also, as terrible as the pandemic is, it's cast a spotlight on how governments can use science and data to respond to global crises, and the coming economic recovery will probably go hand in hand with restructuring national economies so that they can use more clean energy. The election of Joe Biden will also probably help, considering he's pledged very serious action on climate change.
And as I said above, the Biden administration will take serious action on this (especially if Democrats control the Senate), so there's good reason to except CO2 emissions to decrease even more in the coming years.
