WHAT ACCELERATES AND COUNTERACTS GLOBAL WARMING

Introduction

Global warming is the worst challenge facing the world in the 21st century . Since the second half of the 20th century , there has been sudden increase in global temperature leading to global warming effect Increased human activities and natural activities have contributed to increase global warming . Global warming has had various negative effects in the world including melting of polar ice and rise in sea levels changes in weather pattern with prolonged drought and torrents of rain disappearance of species , and many others . One

of the main factors that have contributed to global warming is release of green house gases to the atmosphere . Release of gases like carbon dioxide , carbon monoxide nitrite oxide , and others has contributed to green house effect leading to global warming . Although green house gases has been cited as the main source of global warming , there are other minor sources which over the time has led to substantial increase in global temperature . However there are alternative factors counteracting global warming effects which include aerosols and soot , solar variation , and many others

Alternative causes of global warming

The most common indicator used to indicate global warming is the change in average global temperature at the near earth 's surface . Between 1860 and 1900 it is recorded that the earth surface temperature increased by 0 .75oC which is approximately 1 .35oF . Since 1979 , the global temperature at the lower trosphere has recorded an increase of more than 0 .22oC . Before 1850...
