GEOLOGY

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).

Detailed explanation-2: -Natural influences on the climate include volcanic eruptions, changes in the orbit of the Earth, and shifts in the Earth’s crust (known as plate tectonics).

Detailed explanation-3: -Natural processes, such as changes in the sun’s energy and volcanic eruptions, also affect the earth’s climate.

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: -Effects that scientists had long predicted would result from global climate change are now occurring, such as sea ice loss, accelerated sea level rise, and longer, more intense heat waves.
