Here we are referring to the average temperature of air above the ground on Earth.
It has increased by 1°C since 1900. Depending on the scenarios, the rise in temperature could reach 2°C to 5°C by 2100.
At the end of the last ice age years, the average temperature was only 5°C lower than today... and deglaciation took 10,000 years!
