6/17/13, "Greenland Ice Sheet Had Record Melt In 2012 Due To Jet Stream," redorbit.com, Lee Rannals
"According to University of Sheffield research, published in the International Journal of Climatology unusual Jet Stream changes were behind record surface melt of the Greenland Ice Sheet last summer.
The Greenland Ice Sheet (GrIS) experienced a record surface melting in the summer of 2012, with more than 90 percent of the ice-sheet surface melting as of July 11, 2012. That was nearly double the previous record loss seen in 2010, when 52 percent of the GrIS surface had melted.
The team was able to confirm the record melting by using computer model simulations and satellite data. They also analyzed weather station data from on top of and around the ice sheet, showing several new high Greenland temperature records were set last summer.
The study showed that the record surface melting of the ice sheet was mainly caused by highly unusual atmospheric circulation and Jet Stream changes, which also caused last year’s unusually wet weather in England. The analysis showed that ocean temperatures and Arctic sea-ice cover were relatively unimportant factors that helped lead to the record melting.
“The GrIS is a highly sensitive indicator of regional and global climate change, and has been undergoing rapid warming and mass loss during the last 5-20 years,” said lead researcher Professor Edward Hanna from the University of Sheffield’s Department of Geography. “Much attention has been given to the NASA announcement of record surface melting of the GrIS in mid-July 2012. This event was unprecedented in the satellite record of observations dating back to the 1970s and probably unlikely to have occurred previously for well over a century.”
He said they found that a “heat dome” of warm southerly winds over the ice sheet led to widespread melting. These Jet Stream changes did not show up in an Intergovernmental Panel on Climate Change (IPCC) computer model, which could indicate a flaw in this model.
“According to our current understanding, the unusual atmospheric circulation and consequent warm conditions of summer 2012 do not appear to be climatically representative of future ‘average’ summers predicted later this century,” said Hanna. “Taken together, our present results strongly suggest that the main forcing of the extreme GrIS surface melt in July 2012 was atmospheric, linked with changes in the summer North Atlantic Oscillation (NAO), Greenland Blocking Index (GBI, a high pressure system centered over Greenland) and polar jet stream which favored southerly warm air advection along the western coast.”...
“Because such atmospheric, and resulting GrIS surface climate, changes are not well projected by the current generation of global climate models, it is currently very hard to predict future changes in Greenland climate,” the researcher said. “Yet it is crucial to understand such changes much better if we are to have any hope of reliably predicting future changes in GrIS mass balance, which is likely to be a dominant contributor to global sea-level change over the next 100-1000 years.”
Scientists have been trying to determine what led to the 50-year-record ice melt in Greenland. In April a team of scientists wrote in the journal Nature that they determined that the ice melt could be due to thin cloud cover.
“Clouds are still one of the greatest uncertainties in climate models. Even though the current climate models are generally correct, we need better measurements to improve them,” Von P. Walden, principal investigator for the ICECAPS project, said in an NSF statement in April. “We’re doing this to avoid future surprises, and we need to expand our knowledge of the details of how the climate operates.”" via Tom Nelson

Latest global CO2 emissions: US emissions reductions negated by China:

"Notice that the U.S. is far and away the leader in reducing carbon dioxide (CO2) emissions, while China primarily is responsible for pushing global CO2 emissions higher. In fact, CO2 emissions growth in China more than offsets all the CO2 savings that we have achieved in the U.S."

11/29/12, 134 scientists write to UN Sec. Gen., ask him to desist from blaming climate disasters on global warming that hasn't happened: "Global warming that has not occurred cannot have caused the extreme weather of the past few years."

China controls world CO2.

8/16/12, “AP IMPACT: CO2 emissions in US drop to 20-year low,” AP, Kevin Begos
“In a surprising turnaround, the amount of carbon dioxide being released into the atmosphere in the U.S. has fallen dramatically to its lowest level in 20 years and government officials say the biggest reason is that cheap and plentiful natural gas has led many power plant operators to switch from dirtier-burning coal.
Many of the world's leading climate scientists didn't see the drop coming in large part because it happened as a result of market forces rather than direct government action against carbon dioxide."...
============================
$18.5 billion worth of climate regulations were issued in 2012 alone. Without congress. "The vast majority of “laws” governing the
United States are not passed by Congress but are issued as regulations.""In 2011, the US Congress passed a total of 81 new “laws” while government agencies issued 3,807 new regulations." So you see, congress is irrelevant.
More Obama executive action: 6/12/13, "Obama Quietly Raises ‘Carbon Price’ as Costs to Climate Increase," "Buried in a little-noticed rule on microwave ovens is a change in the U.S. government’s accounting for carbon emissions that could have wide-ranging implications for everything from power plants to the Keystone XL pipeline. The increase of the so-called social cost of carbon, to $38 a metric ton in 2015 from $23.80, adjusts the calculation the government uses to weigh costs and benefits of proposed regulations. The figure is meant to approximate losses from global warming such as flood damage and diminished crops."

News of US CO2 plunge has been described as:
- “Surprising,“
- “little noticed,“
- “dramatic,“
- “stunner,“
- “most people are surprised to learn,“
- “quiet but tremendous progress,”
- “major long term implications,”
- “game changing,”
- “shocker,”
- “huge contrast to the forecast.”
=============================
A May 2013 CBO report commissioned by Rep. Henry Waxman (D-Ca.) states US on its own has little effect on global climate:
p. 14: "Acting on its own, the United States could have only a modest effect on the amount of warming."
May 2013 CBO report,"Effects of a Carbon Tax on the Economy and the Environment"
================================
The May 2013 Waxman commissioned report also says further US CO2 reductions will be meaningless, that global emissions won't improve without significant reductions from countries like China and India (page 14, left column), and that any further US CO2 reductions:
p. 14, "would be offset by increases in emissions overseas—."...

"(Incidentally, the phrase "extreme weather" did not begin to appear frequently in New York Times articles until around 2010, when it was starting to become clear that global warming had really stopped, at which point the global warming story was changed to the extreme weather story.)"...
==============================
Global Warming ‘action’ was mandated and institutionalized in US government in 1990 by George Bush the 1st in the “U.S. Global Change Research Act of 1990.” CO2 reduction is mentioned near the end in Sec. 204, item 4.
Devoting 13 federal agencies to ‘climate’ matters is hardly lagging in “action.”
Trillions have been taken from US taxpayers for climate endeavors via agency budget allocations, tax subsidies, diversion of US military to climate or green projects, countless federal regulations, vast sums shipped out in no strings foreign aid for ‘climate’ capacity building, etc.
Other countries’ CO2 hasn’t dropped despite hundreds of billions spent on cap and trade and extra taxes. This isn’t to say the US government hasn’t become business partners with the ‘climate’ industry.

Obama takes executive 'climate action' in Nov. 2012 by giving $6 billion US taxpayer dollars for 'clean energy' to the Sultan of Brunei who owns 5000+ cars and to the Pres. of Indonesia, whose country is so corrupt even the World Bank says crime adds 20% to costs.

P.S. Obama's partners in crime, the GOP, will do whatever Obama wants. They owe him big time for helping them defeat the Tea Party in 2012.
