Answer 2

Answer:

Global warming is long-term rise in the average temperature of the Earth's climate system, an aspect of current climate change shown by temperature measurements and by multiple effects of the warming.[1][2] The term commonly refers to the mainly human-caused observed increase in global surface temperatures and its projected continuation.[3] In this context the terms global warming and climate change are commonly used interchangeably,[4] but climate change includes both global warming and its effects, such as changes to precipitation and impacts that differ by region.[5] There were prehistoric periods of global warming,[6] but many observed changes since mid 20th century have been unprecedented compared to records over decades to thousands of years.[1][7]
