Thirty-five years have passed since its creation and 33 years since the IPCC
First Report was released, particularly from Group I, which aims to evaluate the
available scientific information on climate change. Since then, the global
average temperature was reported in the last 100 years (1880 - late 1980), with
the five warmest years occurring in the 1980s and a detectable increase in the
mean sea level. In addition, the report revealed evidence of an increase in
greenhouse gas (GHG) emissions due to human activities, which, if continued,
would result in additional warming of the Earth's surface air.
These first findings continued appearing in the coming reports, with an
increasing degree of certainty, and today, the IPCC has indicated in its latest
2023 Report that global warming is real and of anthropogenic origin.
