Question

explain gobal warming in long type answer​

Answer 1

In a 2008 NASA article on usage, Erik M. Conway defined global warming as "the increase in Earth's average surface temperature due to rising levels of greenhouse gases", while climate change was "a long-term change in the Earth's climate, or of a region on Earth".

Answer 2

Global warming is a long-term rise in the average temperature of the Earth's climate system, an aspect of climate change shown by temperature measurements and by multiple effects of the warming.[2][3] The term commonly refers to the mainly human-caused observed warming since pre-industrial times and its projected continuation,[4] though there were also much earlier periods of global warming.[5] In the modern context the terms global warming and climate change are commonly used interchangeably,[6] but climate change includes both global warming and its effects, such as changes to precipitation and impacts that differ by region.[7][8] Many of the observed warming changes since the 1950s are unprecedented in the instrumental temperature record, and in historical and paleoclimate proxy records of climate change over thousands to millions of years.[2]
