Answer:
Step-by-step explanation:
increased levels of carbon dioxide from burning fossil fuels
Fossil fuels release carbon dioxide into the atmosphere. The burning of fossils shoots up carbon emission and leads to gloabl warming.
Carbondioxide is one of the greenhouse gases. Others are methane, water vapour.
Incoming radiation that reaches the surface can either be reflected or be absorbed on the earth surface. The part that is absorbed helps keep surface temperature in check. The reflected component of the radiation can get trapped when they come in contact with greenhouse gases like carbondioxie. The gas prevents the radiation from escaping the earth.
As the radiation lingers, it shoots up the earth temperature significantly.
The more the gases in the atmosphere the more the temperature rises.
Carbondioxide emission from various sources, chief of which is through burning of fossil fuels in industrial processes and automobiles have become a global problem.
When the earth warms, polar ice would recede and add more water to hydrosphere. This has been one of the leading cause of the increasing level of inundation the earth has been plagued with over the years.
