Blog Question


Blog about global warming.

Global warming is caused by an increase in global temperatures. Many scientists believe that climate change is for sure happening, and that human activities are the primary driver. Increase in temperature is also caused by the increase in human greenhouse gas concentrations. Global warming may also cause an increase in sea levels because as more glaciers melt, they add to the amount of water in big bodies of water. It may also cause and increase in soil moisture in North America.
