ICE AGE: THE "MELTDOWN"

Scientists believe that our planet will go through another ice age due to changes in its orbit years from now (around 10,000 to be exact!). However, a new study shows it is possible the ice age may be prevented; instead the planet will continue in a "meltdown" or remain the same. I came across an article on ABC science news which discusses this possible ice age. Professor Thomas Crowley and Dr William Hyde recently created a journal entitled Nature. They believe it is possible the ice age could be by-passed or simply not occur due to the Co2 levels in the atmosphere. Don't confuse their opinion as a defense to Global Warming, it simply is just a theory that our planet will remain the same instead of freezing over.

"In September, a scientific research consortium called the Global Carbon Project (GCP) said that atmospheric concentrations of CO2 reached 383 parts per million (ppm) in 2007, or 37% above pre-industrial levels."
"Present concentrations are 'the highest during the last 650,000 years and probably during the last 20 million years,' the report says"

These two quotes are facts in which our CO2 levels are higher then they have ever been and scientists believe even if we were to cute back on our CO2 emissions, it would probably be enough to stop a future ice age. I think it is important for our planet to go in and out of different climates whether it is a meltdown or an ice age. It creates a clean slate to start with new, fresh resources. However, an ice age would obviously be a major set back in our society and the progress we have made as a species. Good think this ice age is planning to come for thousands of years and I hope we know either how to take care of it then or hope the CO2 emissions can help prevent freezing!!
