WHAT CAUSES GLOBAL WARMING????


Global warming is caused by several things, which include man-made or anthropogenic causes, and global warming is also caused by natural causes.

Natural causes are causes that are created by nature. One natural cause is a release of methane gas from arctic tundra and wetlands. Methane is a greenhouse gas and a very dangerous gas to our environment. A greenhouse gas is a gas that traps heat in the earth's atmosphere. Another natural cause is that the earth goes through a cycle of climate change. This climate change usually lasts about 40,000 years.

Recently, scientists have recently discovered that it is not greenhouse gasses that cause global warming but nature itself that contributes to the phenomenon that is global warming. A report on Fox News says that the gasses that trees produce combined with the waste in the soil and the hydrogen in the water rise up into the atmosphere therefore heating the planet. The report has been proven credible as thousands of members of the science industry came to discuss plans to stop global warming forever.
