The rate of increase has been measured. Any 'projection' of future levels of CO2e are calculated based on current trends. Of course these increases could change if human production of ghgs changes. There is a projected range and MU.
The question is, what will happen if ghgs continue to rise at current rates? We know ghgs retain extra energy in the climate cycle, what effects on weather ( various indicators)will this have in the long term.
If ghgs continue to rise what will be the effects in 100, 500,1000 years time?
My problem with the whole topic isn't with scientists it with the media and shonky journos who can't read a science report properly and arw only interested in a headline to sell
The only 'alarmism' us perpetuated in the media by butchering science reports and cherry picking quotes out of context. Alot of *** bashing of the very low probability senarios because don't understand probability and assume the worst case senarios have been pushed as high probability with they are not.
100 yrs, 2℃ increase in energy, 1m sea level rise.
Let wait and see want happens, because we don't have another Earth as a control to experiment on...
