Warming has occurred twain in the northern and southern hemispheres as well as over oceans.

There atomic number 18 several(prenominal) evidences of orbiculate warming, such as the melting of glaciers, decreased snow subvention in the northern hemisphere, and warming below ground.         There are several regio n-specific theoretical accounts as well, wh! ich give us the evidence the fix that global warming has on the world today. The first example is that low-lying areas in the Indian subcontinent, such as Bangladesh and environ areas, are regularly being flooded. The flooding can be explained by global warming, which leads to increases in sea levels as glaciers and snows caps melt, and excessively as water expands when heated, the sea...
