57% of South Africans have favorable opinions of China. 50% say the same of the U.S., marking the first time ratings of China are higher than ratings of the U.S. since we began tracking South Africans’ opinion of these countries in 2008.

Yet another nail in the coffin for the "what about China" argument against bold climate action in the US.
The US is the world's largest oil and gas producer. Yet, "China is now making more money from exporting green technology than America makes from exporting fossil fuels."
China’s clean-energy revolution will reshape markets and politics
The world’s biggest manufacturer now has an interest in the world decarbonising

RIP Jane Goodall, who has died at 91.
She was a gentle disrupter who reshaped how we understand our place in nature. Her research with chimpanzees revolutionized science, and her boundless optimism touched the world.
