... as explained in this BBC report:
"Atmospheric concentrations of carbon dioxide and other greenhouse gases once again reached new highs in 2018.
The World Meteorological Organization (WMO) says the increase in CO2 was just above the average rise recorded over the last decade."
The fact that this just keeps going up and up really shows how far we have to go to take it seriously. Slowing the rise is not good enough. Stopping the rise is not. We to get it going DOWN and fast. Even then it will takes years to really make a difference. It seems not to be lack of knowledge but of political will or due to deliberate blindness.
