400 ppm: A Dangerous Pollution Milestone Has Been Passed

The concentration of carbon dioxide in Earth’s atmosphere has reached the 400 parts per million (ppm) milestone today according to the U.S. National Oceanic and Atmospheric Administration (NOAA).
 
Over the last million years, CO2 never exceeded 280 ppm (based on actual readings of atmospheric chemistry from Antarctic ice core data.) Concentrations of greenhouse gases (GHG) are a very different measurement than emission rates. Concentrations have a very long lag time and will not be able to be decreased except over centuries, while emission rates can go down overnight. It is critical to start reducing emissions, because existing concentrations mean that we will see warming over the next 100 years from today’s emissions.
 
ETA: Scientists believe the rise portends large changes in the climate and sea level.

Peter Kent, on Wiki:
 
On Jan. 24, 1984, the CBC television program The Journal broadcast a full edition documentary called "The Greenhouse Effect and Planet Earth." It was hosted, narrated and written by Kent. Broadcast more than 27 years ago this may be one of the first major media reports on the subject. Kent concluded with these words: "The greenhouse effect must be considered as the world's greatest environmental concern."[6]
 
He's sure changed, eh?  :mad2

Why NASA’s latest photo of Alaska is freaking people out

NASA writes (without saying “global warming”):   

“The same ridge of high pressure that cleared Alaska's skies also brought stifling temperatures to many areas accustomed to chilly June days. Talkeetna, a town about 100 miles north of Anchorage, saw temperatures reach 96°F on June 17. Other towns in southern Alaska set all-time record highs, including Cordova, Valez, and Seward. The high temperatures also helped fuel wildfires and hastened the breakup of sea ice in the Chukchi Sea.”

Wow quite the pics.


Obama gives a big speech today on climate change. I saw coal shares have plunged, so there's a clue, and a call to carbon cuts. Wanna bet he doesn't mention Keystone. What I don't get is if he does call for carbon cuts and then goes ahead and gives X the go ahead he's basically letting one cancel out the other, can't do both.  :confused

Heat Wave May Threaten World’s Hottest Temp. Record
 
excerpt (from a much longer article...):
 
Some computer-model projections show the ridge of high pressure this week extending all the way northward into Alberta, Canada while the trough retrogrades, or moves from east-to-west, which is the opposite of the typical movement of weather systems in the northern hemisphere. Calgary, Alberta is beginning to recover from record flooding, and this weather means that the same area that just experienced a deluge could be in store for unusually hot weather, and the public health hazards that come along with it.
 
Some scientists think the jet stream in the Northern Hemisphere is becoming more prone to such extremes due to the changes wrought by melting Arctic sea ice from global warming, and it's an active area of scientific research.
 
(hot weather in Alberta mixed with all that water... sounds like a prescription for unbearable humidity)

Obama did mention Keystone - basically he said he will approve XL if it can be proven that expansion of the tar sands projects will not increase CO2 pollution. Yes, he did say "tar sands".  :))
 
Obviously pollution will increase from expanded tar sands poduction, and folks are already speculating that means a "NO" from Obama. But Joe Oliver remains optimistic.  :mad2 
 
 
ETA: Responding to Obama, Joe Oliver said "there is no tar in the oilsands".

McQuaig: Corporate power blocks action on climate change
 
excerpt:
 
Perhaps the only thing more stunning than Alberta’s ruinous flooding has been the realization that not even a disaster of this magnitude, right in the heart of oil country, seems sufficient to break the torpor surrounding climate change. Indeed, federal and Alberta authorities seem undeterred in their dream of turning Canada into an energy superpower, even if it means immersing the country neck-deep in water.

Yes and BB, did you see the Koch Pledge Tied to do nothing on climate change?


Signatories include the entire Republican leadership in the House of Representatives, a third of the members of the House of Representatives as a whole, and a quarter of U.S. senators.

That's the first I've heard of the "Koch Pledge". Scary.
 
I've seen other links where the Koch's are trrying to influence PBS programming with their donations, and buy up significant US newspapers in advance of 2014 and 2016.
 
The Koch's empire is growing, along with their influence - they are the main financial backers of the Tea Party.
 
Jeff Daniels on HBO's The Newsroom summed it up: "The Tea Party are America's Taliban".

74F already, feels like it might go up to 80. Very rarely does it go past 72 here.
