GEOLOGY

Detailed explanation-1: -Since the Industrial Revolution, human activities have released large amounts of carbon dioxide and other greenhouse gases into the atmosphere, which has changed the earth’s climate. Natural processes, such as changes in the sun’s energy and volcanic eruptions, also affect the earth’s climate.

Detailed explanation-2: -Human activity has rapidly increased the emission of greenhouse gases to the atmosphere. Since the start of the Industrial Revolution, in about 1750, human activities such as burning fossil fuels, including coal and oil, have increased greenhouse gas concentrations in our atmosphere.

Detailed explanation-3: -Causes of Climate Change. Generating electricity and heat by burning fossil fuels causes a large chunk of global emissions. Most electricity is still generated by burning coal, oil, or gas, which produces carbon dioxide and nitrous oxide – powerful greenhouse gases that blanket the Earth and trap the sun’s heat.

Detailed explanation-4: -Natural Causes of Climate Change Over the course of Earth’s existence, volcanic eruptions, fluctuations in solar radiation, tectonic shifts, and even small changes in our orbit have all had observable effects on planetary warming and cooling patterns.

Detailed explanation-5: -A New York Times analysis found that 23 rich industrialized countries are responsible for 50 percent of all historical emissions and more than 150 countries are responsible for the rest.
