Which is an advantage of safely using uranium as an energy source rather than using coal? A. Uranium produces energy without polluting the atmosphere, while burning coal can increase the CO2 in the atmosphere.
B. Uranium reduces the amount of thermal pollution, while burning coal can increase the amount of thermal pollution.
C. Uranium is the most cost-efficient energy resource, while coal is the most expensive energy resource.
D. Uranium can be easily mined from deep within Earth, while coal is a hard resource to mine from deep within Earth.

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.
