GEOLOGY

Detailed explanation-1: -The Earth’s average surface temperature has increased by about 1.8°F (1.0°C) since the late 1800s. The 10 warmest years on record (since 1880) have all occurred since 1998, and all but one happened since 2005. See a list of global average annual temperatures here.

Detailed explanation-2: -Global warming describes the current rise in the average temperature of Earth’s air and oceans. Global warming is often described as the most recent example of climate change.

Detailed explanation-3: -We already see effects scientists predicted, such as the loss of sea ice, melting glaciers and ice sheets, sea level rise, and more intense heat waves. Scientists predict global temperature increases from human-made greenhouse gases will continue. Severe weather damage will also increase and intensify.
