The sun is the primary source of energy that drives all the bio geochemical cycles on earth. which statement best describes how the suns energy powers the water cycle?
a) plants require energy from the sun to perform photosynthesis.
b) the suns heat reflects off ice sheets near the polar caps, reducing the overall temperature of earth.
c) heat from the sun drives evaporation, turning water on earth’s surface into water vapor.
d) energy from the sun provides the warmth necessary for cold-blooded animals to survive.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
