we have already reached a +1.2 degrees
increase and we stand on a +3/+4 degree line if nothing
is done to reduce global warming

Based on previous graphic and the 5 scenarios
Decrease CO2
NOW
Decrease CO2
After 2050
CO2 keeps increasing
We will reach
+1.5 degrees 
before 2040 !!
We will reach
+2 degrees 
before 2060 !!
Since we keep
Increasing CO2
Emissions …
We may
remain below 3
degrees if we
reach net zero
around 2050
…
Last time the planet hit +2 degrees
Was 3 million years ago …
CO2 … THE ENNEMY !!
