Earth is warming!! Earth has warmed by about 1ºF over the past 100 years. Increasing the heat of the earth called global warming. This occurrence happened due to serious causes and it’s becoming a very risky problem to the world.
There are many causes of Global warming. The causes are divided into two groups, man-made and natural causes. Man-made causes come from the pollution they made. By burning the fossil fuels (coil or oil) in the factories and industrial unite which cause increase in the atmosphere of greenhouse gas concentrations like water vapor, carbon dioxide (CO2), methane and ozone. However, natural causes come from the release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas. A greenhouse gas is a gas that traps heat in the earth's atmosphere.
There is a big fear in rising sea levels, glacier retreat, Arctic shrinkage, and altered patterns of agriculture are cited as direct consequences of human activities which make a future fear for the creatures.
