CO2 LEVEL PAPERS CHALLENGING AGW


New paper finds natural variability controls CO2 levels, not man

An important new paper published today in Global Biogeochemical Cycles finds that "In contrast to recent claims, trends in the airborne fraction of anthropogenic carbon [dioxide] cannot be detected when accounting for the decadal-scale influence of explosive volcanism and related uncertainties." In other words, after accounting for the large effect of volcanic eruptions, ENSO, and other uncertainties upon natural CO2 sinks, trends in the man-made fraction of atmospheric CO2 "cannot be detected." Thus, despite an exponential increase in man-made CO2 emissions, there is no statistically significant trend in the man-made fraction of CO2 in the atmosphere.

This further suggests that man is not the primary cause of the increase of CO2 in the atmosphere, that temperature is responsible for the increase in CO2 levels due to out-gassing. According to the authors, "Our results highlight the importance of considering the role of natural variability in the carbon cycle for interpretation of observations and for data-model intercomparison."

Note man-made emissions are only about 4% of the total CO2 emissions in the atmosphere, and CO2 only represents about 0.04% of the entire atmosphere

No need to hide
No need to be shy about it

The heightened activities by the world's Rats is because of the impending Keystone XL decision that Obama will soon have to make.




Keystone XL is a Litmus Test
Ultimately, as a Reuters article noted,

"The pipeline is also a litmus test for what you think is the most important problem in the early 21st century."

If Keystone XL is approved, it is an indicator that the United States is still not taking climate change remotely as seriously as it needs to.  It would be a step along the wrong path, exploiting as much of the world's conventional and unconventional fossil fuel reserves as possible rather than looking for ways to leave as much as possible in the ground.

The tar sands present an even bigger test of Canada.  If they continue with their efforts to maximize the tar sands extraction, they will cripple any efforts to reduce their own country's greenhouse gas emissions, and also become an enabler for the rest of the world to continue increasing overall emissions.

Continuing to develop Keystone XL and the tar sands in general will keep us on a path towards a future with very dangerous and potentially catastrophic climate change.  It's time for the USA to take a climate leadership role and signal that the world needs to take a different path by rejecting the Keystone XL pipeline project.

We have twice previously examined the various environmental (including climate) impacts of the proposed Keystone XL pipeline, which would transport oil from the Alberta tar sands in Canada to American refineries at the Gulf of Mexico, where it would then be distributed internationally.  Pressure has been ratcheting up for the Obama Administration to both approve and reject the pipeline. 

In support:

52 US Senators (including 9 Democrats)
The Nature editorial board (to which Dave Roberts wrote an excellent rebuttal)
The Washington Post editorial Board
In opposition:

18 of the nation's top climate scientists, with some impressive names (James Hansen, Michael Mann, Richard Somerville, Jason Box, Raymond Pierrehumbert, Ken Caldeira, John Abraham, Michael Oppenheimer, Mauri Pelto, Ralph Keeling, Terry Root, David Archer, Michael MacCracken, Ted Scambos, James McCarthy, George Woodwell, John Harte, and Alan Robock)

The Keystone XL project.


What will it be?


Will it be politics as usual?

Or America take a lead role in combating climate change?

What fantastic education Professor Nasih Nahle has.... he studied anything and everything from fruit flies to... I don't know what.

How could every professor you disagree with is a fake? What about you...yourself? Are you a fake? Prove that you are genuine... i.e. if ever you are one!

Very simple......


Seneca did a simple Google search......


Simple task for you.....how many peer reviewed papers the guy published?

What in your own words did the guy do....i mean besides taking money from lobbyists?
