What is global warming and how does it affect weather temperature and ocean water levels?

Answer 1

Global warming is the rising temperature of the planet, all over. It is happening now, largely because we burn fossil fuels (coal, oil and natural gas) which releases carbon dioxide emissions.

If global warming continues, the long-term weather, that is, the climate will change. Predictions include colder, wetter, warmer, drier in many different places. Weather events like storms, tornadoes, floods, droughts etc may all get more severe and more frequent.

Ocean levels have been rising, and they will continue to rise. The present rise is about 3 mm a year, but this is an increase from 20 years ago. Sea levels rise because the water in the oceans expands when it warms. Melting glaciers and ice caps add to this.

Answer 2

Global warming refers to the long-term increase in Earth's average surface temperature due to human activities that release greenhouse gases. As the planet warms, it disrupts weather patterns, leading to more frequent and severe heatwaves, storms, and other extreme weather events. Rising temperatures also cause polar ice caps and glaciers to melt, contributing to the rise in ocean water levels, which can result in coastal flooding and habitat loss.
