Snow cover and ice-albedo feedback is a powerful climate process where bright snow and ice reflect solar radiation, cooling the Earth. As global temperatures…
Climate reparations refer to the idea that wealthy, high-emitting nations should compensate poorer, low-emitting nations for the loss and damage caused by climate change,…
Quick verdict: Ocean alkalinity enhancement is a promising but unproven carbon removal method that could also mitigate ocean acidification. It faces significant uncertainties regarding…
A marine heatwave is a prolonged period of unusually warm ocean temperatures that can disrupt marine ecosystems, fuel extreme weather, and affect human communities.…
Freshwater change encompasses shifts in water availability, quality, timing, and distribution driven by climate change, land use, pollution, and other factors beyond direct human…
Deforestation is the permanent conversion of forest to non-forest land uses, while forest degradation is the reduction of a forest's quality and capacity to…
