Climate change

This article is about contemporary climate change. For historical climate trends, see Climate variability and change.
Average surface air temperatures from 2011 to 2021 compared to the 1956–1976 average
Drivers of climate change from 1850–1900 to 2010–2019. There was no significant contribution from internal variability or solar and volcanic drivers.
Scenarios of global greenhouse gas emissions. If all countries achieve their current Paris Agreement pledges, average warming by 2100 would still significantly exceed the maximum 2 °C target set by the Agreement.
Economic sectors with more greenhouse gas contributions have a greater stake in climate change policies.
