Has there been any progress at all in reducing global warming pollution? Is anybody doing anything to deal with climate change seriously? Is it all bad news, or are there at least a few rays of hope?

And in the last few months, three new datasets have been released that show us what has been happening to Amazon deforestation since the 1990s.
