Greenhouse gases trap some of the heat that results when sunlight heats the Earth's surface. Three important greenhouse gases are shown symbolically in this image: carbon dioxide, water vapor, and methane.

温室効果ガスが地球環境に与える影響とメカニズム

温室効果ガス地球温暖化二酸化炭素メタン
Glacial and interglacial cycles as represented by atmospheric CO2, measured from ice core samples going back 800,000 years. The stage names are part of the North American and the European Alpine subdivisions. The correlation between both subdivisions is tentative.

氷期と間氷期のメカニズム地球の気候サイクルと第四紀の変動

氷期間氷期第四紀気候変動
Temperature variations during the Holocene from a collection of different reconstructions and their average. The most recent period is on the right, but the recent warming is seen only in the inset.

Global surface temperature reconstruction over the past 2000 years using proxy data from tree rings, corals, and ice cores in blue.[44] Directly observed data is in red.[45]

気候変動の現状とメカニズム地球温暖化がもたらす影響と未来

気候変動地球温暖化温室効果ガス二酸化炭素
Colored bars show how El Niño years (red, regional warming) and La Niña years (blue, regional cooling) relate to overall global warming. The El Niño–Southern Oscillation has been linked to variability in longer-term global average temperature increase, with El Niño years usually corresponding to annual global temperature increases.

The relative magnitude of the top 6 climate change feedbacks and what they influence. Positive feedbacks amplify the global warming response to greenhouse gas emissions and negative feedbacks reduce it.[1] In this chart, the horizontal lengths of the red and blue bars indicate the strength of respective feedbacks.

Atmospheric CO2 concentration measured at Mauna Loa Observatory in Hawaii from 1958 to 2023 (also called the Keeling Curve). The rise in CO2 over that time period is clearly visible. The concentration is expressed as μmole per mole, or ppm.
