Carbon Dioxide Levels Climb Into Uncharted Territory for Humans

RATE THIS! +35
Posted in Science on 11th Apr, 2014 02:01 AM by AlexMuller

The amount of carbon dioxide in the Earth's atmosphere has exceeded 402 parts per million (ppm) during the past two days of observations, which is higher than at any time in at least the past 800,000 years, according to readings from monitoring equipment on a mountaintop in Hawaii.

 

Carbon dioxide, or CO2, is the most important long-lived greenhouse gas responsible for manmade global warming, and it is building up in the atmosphere due to the burning of fossil fuels such as coal, oil and natural gas.

 
Once emitted, a single molecule of carbon dioxide can remain aloft for hundreds of years, which means that the effects of today's industrial activities will be felt for the next several centuries, if not thousands of years.
 
Carbon dioxide and other greenhouse gases, such as methane, warm the planet by absorbing and redirecting outgoing solar radiation that would otherwise escape back into space.

So many alarms are ringing and yet there is so much resistance to see this as an emergency - governments should call for global cooperation to save the planet from global warming

Yes, and there are so many other reasons to get off of fossil fuels and embrace a clean energy future. 
Fossil fuels don't just burn to CO2, but release a slew of other toxic chemicals that probably aren't good for our health Reply

The underlying significance of all this is that the rate of carbon dioxide increase is higher than ever at the moment, year after year now it’s been more than 2 ppm per year Reply
