We put in only 30 Gigatonnes.
The biosphere pumps out 550 Gigatonnes of carbon yearly;
Between 2002 and 2016 the ice sheet lost mass at a rate of around 269 Gigatonnes per year.
The models show a remaining 1.5C“carbon budget” from 2018 to 2100 of between -175 and
400 Gigatonnes of CO2(GtCO2).
This“Great Green Wall of Cities” would capture 0.5-
5 Gigatonnes of carbon dioxide per year and stock carbon for centuries.
Fossil fuel burning dominate GHG emissions and
led to grow by 2% in 2018 reaching a record 37.5 Gigatonnes per year.
CO2 emissions would rise by 10 percent to 36 Gigatonnes in 2040, mostly driven by growth in oil and gas.
Inorder to stay under 2°C, by the year 2030,
emissions would need to be 25%(15 Gigatonnes of CO2) lower than in 2018.
Those of us who work on climate change, we tend to think about Gigatonnes of greenhouse gases and we tend to forget that this is all about humans-
that's what it's all about.
