What is global warming?
<|assistant|>
Global warming is an increase in the average temperature of the earth’s atmosphere and oceans due to human activities, such as the burning of fossil fuels and emissions of certain chemicals. The increase in temperature leads to climate change, with consequences like more frequent and intense extreme weather events, as well as rising sea levels that threaten our coastal cities. This phenomenon is known as global warming because the increase in average temperature is warming all parts of the planet, including the poles which are usually the first to cool. Global warming is an ever-present, long-term problem that could result in massive changes to global climate, infrastructure, and ecology if we do not reduce our emissions and mitigate its effects.
