Globale monatliche Temperaturen seit 1850, Animation nach den HadCRUT4-Daten des Met Office. Gemäß IPCC betrug der Temperaturanstieg der Erdoberfläche im Zeitraum 2011–2020 relativ zu 1850–1900 etwa 1,09 °C (wahrscheinliche Spanne: 0,95 bis 1,20 °C).

Climate change has happened constantly over the history of the Earth, including the coming and going of ice ages. But modern climate change is different because people are putting carbon dioxide into the atmosphere more quickly than before. Since the 1800s, people have recorded the daily temperature. By about 1850, there were enough places measurin...
Some people burn less fossil fuel. Countries try to emit less greenhouse gases. The Kyoto Protocolwas signed in 1997. It was meant to reduce the amount of greenhouse gases in the atmosphere to below their levels in 1990. However, carbon dioxide levels have continued to rise. Energy conservation is used to burn less fossil fuel. People can also use ...
People can change how they live because of the effect of climate change. For example, they can go to places where the weather is better, or build walls around cities to keep flood water out. This cost money, and rich people and rich countries will be able to change more easily than the poor.
As early as the 1820s some scientists were discussing climate change: sunlight heats the surface of the Earth, and Joseph Fourier suggested that some of the heat radiatedfrom the surface is trapped by the atmosphere before it can escape into space. This is called the greenhouse effect. In 1856 Eunice Newton Footedid tests which showed that the warm...
Sea level is rising because water over 4 °C (39 °F) expands when it gets warmer. Probably more important is the melting of ice sheets. The Antarctica and Greenlandice sheets are melting. Sea level will rise between half and one meter by 2100, and between 2 and 7 meter by 2300. Low-lying areas such as Bangladesh, Florida, the Netherlandsand other ar...
What is climate change National GeographicKidsWhat is climate change? A really simple guide BBCIn common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate.
Der Monat September 2023 war global der wärmste September seit Beginn der Temperaturaufzeichnungen im Jahr 1880, die globale Oberflächentemperatur lag 1,44 Grad Celsius über dem Durchschnitt des 20. Jahrhunderts sowie 0,46 Grad über dem bisherigen Rekord von September 2020. Dies stellt die bisher größte monatliche Temperaturanomalie (in ...
Eine Karte der prognostizierten globalen Erwärmung zum Ende des 21. Jahrhunderts. In diesem verwendeten HadCM3- Klimamodell beträgt die durchschnittliche Erwärmung 3 °C. Bis 2100 wird sich die Erde nach Angaben des IPCC um 1,1 bis 6,4 °C erwärmen, je nach Menge der ausgestoßenen Treibhausgase und der genauen Klimasensitivität.
Vor 3 Tagen · 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 affects all parts of Earth's climate system. Global surface temperatures have risen by 1.1 °C (2.0 °F). Scientists say they will rise further in the future. The changes in climate are not uniform across the Earth. In particular, most land areas have warmed faster than most ocean areas.
