কারণ ও প্রেক্ষাপট

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.

Greenhouse gases absorb and re-emit outgoing longwave radiation, changing the energy balance until the climate system warms.

মূল তথ্য

• 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.
