Q and A with climate change facts! Good to quiz yourself with:) my favorite is: In the past, has Earth been warmer than it is today? If so, does that mean we shouldn't worry about global warming?

NASA (National Aeronautics Space Administration) and NOAA (National Oceanic and Atmospheric Administration) agree that climate change is happening and humans are contributing to it. Many people agree in the United States of America and abroad. MAny believe it is because of greenhouse gases from humans. Scientists are trying to answer some very important questions such as how quickly will the world warm, and what consequences will that have on certain parts of the world. The global temperature average has risen by 1.4 degrees Fahrenheit over the last 100 years. NOAA said that the decade between 2000-2010 was the warmest decade on record. 2005 was the warmest year on record. There have been more intense rainfall and severe heat waves. Sea levels are rising. The Earth does go through warming and cooling because of factors such as sun and volcanic activity. The warming and cooling is partly natural and partly because of humans. The sun's energy has fluctuated but is small in comparison compared to human's effect. The warming is consistent with what happens with heat trapping carbon dioxide. Carbon dioxide can lead to climate changes that can hurt plants, animals, and people. For every 2 degrees Fahrenheit raise 5-15% reductions in crops. 3-10% increase in rain which would create flooding. 5-10% increase in stream flow. 200-400% increase in wildfires in the western United States. Scientists predict that the temperature will rise 2-12 degrees Fahrenheit by 2100. It is not too late too fix climate change!

This websites provides excellent proof of the fact that global warming is real. In the last 650,000 years CO2 levels did not go over 300 ppm. However in recent times the ppm has sky rocketed to 390 ppm. I find it is also frightening that ten of the hottest years occurred in the last 12 years. Coldest records are not being reported as often as they used to be. The top 700 meters of the ocen has rose a frightening .3 degrees Fahrenheit seance 1969. The acidity of the ocean has also risen by 30%. This website backs up my ideas on climate change. I believe and so does NASA that global warming is happening now.

This website is very detailed, it has a graph and excellent proof of global warming.

This link show you that global warming does make an effect on the earth. It tells you lots of good information. I was surprised that the earth has had its hottest temperatures in the last 12 years! There has been no coldest records in a long time.
