Global Warming

NASA has been monitoring the Earth's temperature to monitor global warming. As carbon dioxide levels increase in the earths atmosphere, the planet becomes warmer. There has been a global limit in trying to prevent global warming by setting a limit of how much the earth can heat up. They set the limit at two degrees celsius. Now scientist believe that this number is to high and will cause greater disasters. Such as a two degree increase will cause an ice free arctic. An ice free arctic will raise sea level in the tens of meters. If nothing is done to to prevent the rise in greenhouse gas emissions then the temperature is expected to rise three degrees celsius. This will cause short term events like increase in water vapor in the atmosphere and changes in cloud clover, which will rise or lower temperature. But remember this is only the small effects. Just imagine what the huge effects global warming has on our planet.
