Detailed explanation-1: -These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth’s orbit and levels of carbon dioxide (CO2). Global climate change has typically occurred very slowly, over thousands or millions of years.
Detailed explanation-2: -Emission of greenhouse gases into the atmosphere. Deforestation for human settlements. Overutilization and exploitation of natural resources. Pollution caused by human activities.
Detailed explanation-3: -Shrinking Glaciers As the climate continues to warm and reduce the amount of ice in some places and increase the mass of water (e.g., from oceans, precipitation), the stress on tectonic plates can change-sometimes abruptly.
Detailed explanation-4: -Generating power. Generating electricity and heat by burning fossil fuels causes a large chunk of global emissions. Manufacturing goods. Cutting down forests. Using transportation. Producing food. Powering buildings. Consuming too much.
