In just the latest development in exactly how screwed we are, the Amazon rainforest is now emitting more CO2 than it absorbs.  The carbon emissions are due mainly to wildfires, mostly deliberate to clear land for cattle and soybean farming. The tipping point arrived when the smoke from the flames began producing more CO2 than the remaining rainforest could absorb.

Although still woefully deficient to offset global production, the Amazon rainforest was until recently one of the last major carbon sinks on the planet.  Now, that sink is gone and the Amazon is just another source of greenhouse gasses.

Enjoy your long hot summers, Planet Earth.
