Not this time as all parameters are worsen by each year, Australia and California wildfires, lose of ice, most significantly thawing permafrost at Siberia that contains potential of 100 - 1000 Gt of CH4 (Methane 75 times more potent than CO2 currently there is only 5Gt of methane in atmosphere) which would be enough to tip things over instantly ...
In fact it was never "always 10 years" as tipping point has been considered 450 ppm (it could be sooner), and CO2 is steadily increasing currently is 412.16 ppm. https://www.co2.earth/ https://www.co2.earth/
So we can estimate how much time is left by progression.
- quixoticelixer- 6y agoRegarding California and Australia they might not be as big CO2 emitters as you might expect as long as the forest grows back well after fires.
- NiceWayToDoIT 6y agoYoung trees cannot not sequester amount of CO2 as mature forests. Not even close. And trends are showing that droughts will continue, so there will be not enough water for them to grow.
- quixoticelixer- 6y agoNo, but young forests grow into old forests and while they don't hold as much CO2 they sequester it much much faster. (assuming of course that there is good regeneration after fires.)
