GEOLOGY

Detailed explanation-1: -The correct answer is Increased agricultural productivity worldwide.

Detailed explanation-2: -The main impacts are decreases in water availability and crop yields, increasing risks of droughts and biodiversity loss, forest fires, and heat waves.

Detailed explanation-3: -Polar ice caps are melting as global warming causes climate change. We lose Arctic sea ice at a rate of almost 13% per decade, and over the past 30 years, the oldest and thickest ice in the Arctic has declined by a stunning 95%.

Detailed explanation-4: -“Climate change” encompasses global warming, but refers to the broader range of changes that are happening to our planet, including rising sea levels; shrinking mountain glaciers; accelerating ice melt in Greenland, Antarctica and the Arctic; and shifts in flower/plant blooming times.

Detailed explanation-5: -Human activities are at the root of this phenomenon. Specifically, since the industrial revolution, carbon dioxide and other greenhouse gas emissions have raised temperatures, even higher in the poles, and as a result, glaciers are rapidly melting, calving off into the sea and retreating on land.
