THREAD (of my presentation at #UFGC19)
Where have we been the last 150 years?
Putting CO₂ into the atmosphere, first from land-use change, then coal, oil, & then gas. This has increased CO₂ in the atmosphere, led to a ~1°C temperature increase, & various climate impacts.

It is unlikely that the ~1°C warming can be reversed, & the Paris Agreement is about limiting future warming & impacts.
A strong interpretation of Paris, below 1.5°C, requires cutting CO₂ in half by 2030, hitting zero ~2050, & negative thereafter. Exceedingly ambitious.

Bonus slide:
CO₂ removal has to start today, to reach the scales necessary to stay below 1.5°C. There are legitimate concerns about large-scale CO₂ removal, & less CO₂ removal requires more rapid short-term reductions & less non-CO₂ emissions.

Here is my presentation at the opening session of the #NordicEVS, I discuss what has driven changes in CO₂ emissions in the last decades & where we need to go into the future.

1. Where have we been in the last century? We have been busy burning coal, oil, gas, and cutting down forests. Emissions have grown except for short economic downturns or spikes in deforestation (fires).
2. Where do we want to go? For 1.5°C we need CO₂ emissions to go down much faster than we went up. CO₂ emissions down 50% in a decade, zero by 2050, negative thereafter. We have to start remove CO₂ now, to reach the necessary scale at the end of the century.
