Former Coordinating Lead Author of the IPCC
In this video, Kevin explains how global warming has been observed and measured from a scientific perspective. He looks at rising global temperatures caused by increased CO2 levels and how Earth’s energy imbalance has risen over time. He then explains how global warming has been observed through rising ocean temperatures and sea levels, as well as through changes in the land and the ice.

The observational evidence proving global warming is mounting and extremely visible. Every year seems to be record-breaking, with the ocean found to be at its warmest state ever. Land and sea ice is melting, and heatwaves and wildfires are a consequence on land. Ironically, both droughts and heavy rains, with their associated flooding risk, are increasing too. Carbon dioxide levels are at all time highs, the energy imbalance is rising, seas are warming and rising, and there has been significant changes in the land and ice.
Key learning objectives:
Outline how global temperatures, Earth’s energy imbalance and CO2 levels have risen
Outline how global warming has been observed through changes in the oceans, land and ice
