I agree. Any anti carbon solution needs to be global.

That's a a tricky problem since some countries, maybe Russia and Canada, could theoretically come to the conclusion that climate change will actually be a net benefit for them by way of opening up access to resources in their lands. And other countries might come to the conclusion that the benefits of burning lots of carbon fuels to develop and modernize their nations outweigh the risks of climate change.

Our ability to actually reverse the trend of atmospheric carbon seems grim to me.
