GEOLOGY

Detailed explanation-1: -Yes, by increasing the abundance of greenhouse gases in the atmosphere, human activities are amplifying Earth’s natural greenhouse effect.

Detailed explanation-2: -Between 1990 and 2021, the warming effect on our climate (known as radiative forcing) by long-lived greenhouse gases rose by nearly 50%, with carbon dioxide accounting for about 80% of this increase.

Detailed explanation-3: -That extra heat is driving regional and seasonal temperature extremes, reducing snow cover and sea ice, intensifying heavy rainfall, and changing habitat ranges for plants and animals-expanding some and shrinking others.

Detailed explanation-4: -Accounting for about 76 percent of global human-caused emissions, carbon dioxide (CO2) sticks around for quite a while.

Detailed explanation-5: -CO2 accounts for about 76 percent of total greenhouse gas emissions. Methane, primarily from agriculture, contributes 16 percent of greenhouse gas emissions and nitrous oxide, mostly from industry and agriculture, contributes 6 percent to global emissions. All figures here are expressed in CO2-equivalents.
