Disagree re the USA.China has gone full gun on climate action. They are the biggest manufacturer of solar panels in the world and have set up a bunch of electric car companies.
The US is likely to start taking it seriously after the 20th of January.
I think India is behind the curve but we all have to do what we can instead of making excuses.
You can change the government, who might be amenable to climate change issues in other countries, but the American motorists like their cars and the petro chemical industry, like the gun lobby in America are very powerful.
