Global warming is evidenced by rising temperatures, melting ice sheets, and increasing sea levels, often influenced by both natural and human-induced factors.
Global warming refers to the increase in global average air and ocean temperatures primarily caused by the rise in greenhouse gases like carbon dioxide. One of the key signs of global warming is the decrease in ice sheets due to rising temperatures, leading to a rise in sea level. A natural factor of climate change includes phenomena like volcanic eruptions, contributing to atmospheric changes.
