Greenhouse Gases Have Reached the Tipping Point
Greenhouse gas levels have reached a dangerous level. Current levels of greenhouse gases equal to carbon dioxide are 390 million parts per million. This level is considered to be a tipping point in the science world. Tim Flannery, a climate control expert, says "The amount of greenhouse gas in the atmosphere is already above the threshold that can potentially cause dangerous climate change. We are already at risk...It's not next year or next decade, it's now." We need to act fast to control our emissions. In the 1990's, carbon emissions grew by less than 1% per year. From 2000-2008, these emissions grew at a rate of 3.5% per year. No part of the world showed decline. That's unacceptable, considering the know and proven scientific dangers shown to come along with global climate change. Climate change is also affecting natural disasters, as the disasters attributed to being caused by climate having risen 20% in two decades. We are not only killing the environment, but ourselves as well.
