GENERAL GEOLOGY

Detailed explanation-1: -Climate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle. But since the 1800s, human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil and gas.

Detailed explanation-2: -With no further human influence, natural processes would begin to slowly remove the excess carbon dioxide from the atmosphere, and global temperatures would gradually begin to decline.

Detailed explanation-3: -As these impacts grow in frequency and severity, they will-and in many cases already have-create crises for people and nature around the world. If unchecked, these impacts will spread and worsen with more animal extinction and biodiversity loss, water shortages, and displaced communities.

Detailed explanation-4: -Geological records show that there have been a number of large variations in the Earth’s climate. 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).

Detailed explanation-5: -The earth’s climate is influenced and changed through natural causes like volcanic eruptions, ocean currents, the Earth’s orbital changes, solar variations and internal variability.
