It's the big one this week.
World leaders have gathered in Glasgow for COP26, the two-week long United Nations conference on climate change, and they didn't waste any time announcing some big goals.
Most notable of those is a promise to end deforestation by 2030, which has been signed by more than 100 world leaders, including - crucially - Brazil, which is home to the Amazon rainforest, one of the largest carbon sinks on the planet. Getting Brazil on board, even at this early stage, is vital as deforestation has picked up again in the Amazon in the last few years, hitting a 12-year high last year.
A little less conversation, a little more action
All told the countries that have signed account for roughly 85% of the world's forests, suggesting good global support, although cynics will point to the last agreement from 2014, that failed to do much of anything. Hopefully this time there is more action.
For more great data on climate change and what is at stake at COP26, we recommend checking out the 11 charts from DW and the very cool "draw your own chart" from the FT, which tests how well you know some of the data behind climate change.
