Modern global warming is the result of an increase in magnitude of the so-called greenhouse effect, a warming of Earth’s surface and lower atmosphere caused by the presence of water vapour, carbon dioxide, methane, nitrous oxides, and other greenhouse gases. Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels. Present-day climate change includes both global warming —the ongoing increase in global average temperature —and its wider effects on Earth's climate system.
Climate change in a broader sense also includes previous long-term changes to Earth's climate. Progress of human-induced and observed global warming, greenhouse gas emissions, sea levels, and the remaining carbon budget. Relevant to the Paris Agreement, IPCC AR6 consistent, annually updated.

warming up drills, People often use the terms “global warming” and “climate change” interchangeably, but they are different. Global warming refers to Earth’s rising average temperature, while climate change refers to changes in weather patterns and growing seasons around the world. Human activities, principally through emissions of greenhouse gases, have unequivocally caused global warming, with global surface temperature reaching 1.1°C above 1850-1900 in 2011-2020. What is global warming? Global warming causes, effects, extreme weather, facts, and relation to climate change.
