1.14  Humans will only survive ONE scenario

Humans will only survive ONE of the 5 scenarios outlined by the IPCC, after the year 2041:   SSP1-1.9

An increase of 2˚CELSIUS or more will accelerate the Earth past its 'Tipping Point'. 

The Climate Control system of the Earth is already starting to move into positive feedback loops that will rapidly force highly non-linear increases in the levels of CO2 emissions.

Five new emissions scenarios are consistently used across the IPCC AR6 report to explore the climate response to a broader range of greenhouse gas (GHG), land use and air pollutant futures than assessed in the previous AR5. These 5 scenarios enable future projections of changes to the Earth’s climate system.

These projections account for solar activity and background forcing from volcanoes. Unless otherwise stated, results over the 21st century relative to 1850–1900 are provided for the:

• near-term (2021–2040)  the next 20 years.     

• mid-term (2041–2060)   in 20 to 40 years from now. 

• long-term (2081–2100)   in 60 to 79 years from now.

Just a 2 degree Celsius increase in average global temperatures is deemed to be a “VERY DANGEROUS BOUNDARY” line for the continuance of human civilisation on Earth.  [ WE CANNOT RISK INCREASING 2˚CELSIUS ]
