Statistics report on global warming

Global warming

Global warming is the gradual heating of Earth's surface, oceans, and atmosphere caused by human activity (primarily by burning fossil fuels) that release carbon dioxide (CO2), methane (CH4), and other greenhouse gases into the atmosphere. Warming can result in many severe environmental alterations, eventually impacting human health. It can also cause a rise in sea level, increased risks of droughts and floods, and threats to biodiversity, to name a few.

This report presents graphs and tables about global warming. Focusing on temperature anomalies, it also provides data on different cities and scenarios for future.

This report is part of a series of reports on the impacts of climate change.
