It's just below this CO2 thing.
New CO2 Milestone: 3 Months Above 400 PPM
http://www.climatecentral.org/news/co2-milestone-400-ppm-climate-17692
April fell first. It lasted through May. Now June will be the third month in a row with average carbon dioxide levels above 400 parts per million.
Atmospheric concentrations of the greenhouse gas, which helps drive global warming, havent been this high in somewhere between 800,000 and 15 million years.
And while the 400 ppm mark is somewhat symbolic (as the increase in warming between 399 ppm and 400 ppm is small), it serves to show how much carbon dioxide has been put into the atmosphere since preindustrial times, when concentrations were around 280 ppm. The increase in this and other greenhouse gases in the atmosphere has warmed Earths average temperature by 1.6°F since the beginning of the 20th century. World leaders agreed at a UN summit in 2009 to limit warming to 3.6°F, but prominent climate scientists like James Hansen have said that amount of warming will still be too much.
(snip)
But plants only pull so much CO2 out of the atmosphere in a given growing season. Each year they leave a growing excess of about 2 ppm behind, which is why the 400 ppm mark came earlier this year than last and will come earlier still next year.

You will get a dozen replies and a couple recs, besides mine,,,,you need to add a hot baby comment or a kitten gif.

P.S. I believe the macro level is just too big to absorb or deal with even if the repercussions from the macro level effect pose a much greater danger.

400 PPM CO2.
Really, what the hell does that mean, will be the common response.

(58,355 posts)I wonder how high CO2 and Methane levels would have to reach before it killed all the little Dachshunds in the world?

Thanks very much for the thread, Uncle Joe.

(58,355 posts)dogs, and for that matter kittens, cats, bunny rabbits, goats, sheep, horses, birds, polar bears, and pretty much everything else about life including babies, children, and adults then we should be alarmed about this modern day, pre-historical recording breaking rise of global warming gases, because if its' not checked all those things we love are in danger.
Thanks for the thanks, countryjake.
