Global warming is the long-term rise in Earth's average surface temperature, primarily from increased anthropogenic greenhouse gases.
क्यों और कैसे होता है
कारण और संदर्भ
Global warming is the long-term rise in Earth's average surface temperature, primarily from increased anthropogenic greenhouse gases. The governing relationship is: Greenhouse gases absorb and re-emit outgoing longwave radiation, changing the energy balance until the climate system warms.
यह कैसे काम करता है
Greenhouse gases absorb and re-emit outgoing longwave radiation, changing the energy balance until the climate system warms.
मुख्य तथ्य
- The natural greenhouse effect makes Earth habitable; anthropogenic emissions strengthen it.
- Water vapour is a feedback in current warming, while carbon dioxide is a primary forcing.
- Oceans absorb much of the excess heat in the climate system.
ज़रूरी शब्द
- greenhouse effect
- longwave radiation
- carbon sink
- forcing
- albedo
उदाहरण और केस स्टडी
- Ocean heat uptake moderates atmospheric warming while contributing to thermal expansion and sea-level rise.
