Essay on global warming a matter of serious concern
Answers
Answer:
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] Though earlier geological periods also experienced episodes of warming,[4] the term commonly refers to the observed and continuing increase in average air and ocean temperatures since 1900 caused mainly by emissions of greenhouse gases (GHGs) in the modern industrial economy.[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] Many of the observed changes in climate 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.
Explanation:
Global warming is an increase in earth's average atomspheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. It is an important issue for humans to consider and science to figure out.There are scientifically facts that prove that the earth's temperature is gradually rising .Although greenhouse gases are the main reason for global warming but it is not the only reason other causes are agriculture , road construction etc etc. so we should take svere steps in order to control global warming otherwise life will be impossible on earth.
