Possibly adds 0.9 degrees Celcius
Adds 0.7 degrees Celcius
30 to 50 years from now.
Already have 0.8 degrees Celcius increase today.
Totals a 2.4 degrees Celcius increase.
With the CO2 released today,
90% of heat goes into the oceans.
Resultant heat rise in atmosphere happens 30 to 50 years later
IF EMISSIONS STOPPED TODAY
We would still get a 2.4 degree temperature increase at the end of the century.
BUT emissions aren't stopping.
Add another 1 degree celcius to this for the CO2 released if we took emergency measures to stop all of it.
This is locked in. It will be very hard to stop this. Reference link
AEROSOLS are mainly human pollution. Fine particles released into the atmosphere largely from burning fossil fuels. They have a cooling effect but are short lived. When we stop burning fossil fuels, we stop producing aerosols and therefore get extra warming.
Volcanoes also produce aerosols in the form of sulphur dioxide which cools the planet. This also only stays in the atmosphere for a low number of years.
Death of Coral Reefs
1 metre sea level rise
More severe storms and stronger storm surges
Possible runaway climate change
At currrent rates of CO2 going into the atmosphere and oceans, we will have a 4 to 6 degrees temperature rise somewhere around 2100.
