Global warming is happening. According to the United States Environmental Protection agency brochure entitled, Frequently Asked Questions About Global Warming and Climate Change: Back to Basics, "Scientists have observed a warming trend beginning around the late 1800s. The most rapid warming has occurred in recent decades. Most of this recent warming is very likely the result of human activities." Also according to the US EPA, "Many human activities release “greenhouse gases” into the atmosphere. The levels of these gases are increasing at a faster rate than at any time in hundreds of thousands of years." The earth really is getting hotter. Stated by the Natural Resources Defense Council's website, "Although local temperatures fluctuate naturally, over the past 50 years the average global temperature has increased at the fastest rate in recorded history."

Fred Singer, a atmospheric physicist and a know global warming skeptic, argures that global warming is not occuring, but Singer is using data from satellites that measure the atmospheric tempurature of the Earth rather that using data that states surface tempuratures of the Earth.

Global warming is happening and i think that everybody should make an action to stop this. It is not too late yet and we should try to do something before its to late. If everybody joins together and make an action we can make a difference and stop this.
