Global Warming Facts

March 31st, 2009

Global warming, or climate change as scientist would have us say it is a hot topic that shows no sign of cooling. The rate of warming is increasing according to many respected reports, but it seems some are just not “buying it”. The world’s largest-ever gathering of global warming skeptics took place in New York City on March 8 through the 10, 2009, to confront the issue, “Global warming: Was it ever really a crisis?”. Some things that we have to think about whether or not we regard them as facts are: 1) Measurements of the concentration of carbon dioxide in our atmosphere since 1959 have revealed an increase to 386 part per million in 2008. 2) Average temperatures have climbed 1.4 degrees Fahrenheit around the world since 1880. This does not sound like much, but most of this increase occurred in recent decades according to NASA’s Goddard Institute for Space Studies. The 20th century’s last two decades were the hottest in 400 years and possibly the warmest for several millennia.Are greenhouse gases increasing? It would seem so. The global concentration of CO2 in our atmosphere today far exceeds the natural range over the last 650,000 years. By the end of the 21st century, we could expect to see carbon dioxide concentrations of anywhere from 4500 to 1250 parts per million. Global warming seems to be with us, and for good or for bad, it may be here to stay.
