Humans are causing damage to the atmosphere. The world is heating up incredibly. There will be more droughts and rainstorms, as well as more violent typhoons and hurricanes. The global average air and ocean temperatures have increased. There is melting of snow and ice, and the sea levels are rising.
The Intergovernmental Panel on Climate Change has suggested the following:
Sea ice will shrink in the Arctic and Antarctic. late summer sea ice could disappear almost entirely at the end of the 21st Century.
Heat waves, droughts and rainstorms will continue.
The number of hurricanes will decrease, but the ones that do occur will be more powerful.
Ocean currents responsible for the Gulf Stream will slow by as much as 25%.
Sea levels will rise, and the Greenland ice sheet will be eliminated.
All this goes to show that human beings are not the kindest or most considerate beings on the earth.
