Update: See Warmists trapped by irony off Antarctica by Andrew Bolt So who are the real denialists? See how a boat was shown in ice free Commonwealth Bay in 1912!!!

WUWT and WeatherBell help KUSI-TV with a weather forecasting request from ice-trapped ship in Antarctica Akademik Shokalskiy

Also in the UK Guardian today they report the latest rescue attempt was twarted by an Antarctic blizzard.

See how the UK Mail relished the story and enjoy the comments.

--------------

After nearly a week trapped by deep Antarctic ice, the 74 passengers aboard an expedition vessel could soon be freed.

But based on the troubles of the last few days, no one’s sure exactly when that might happen.

An Australian icebreaker ship Aurora Australis is headed toward the Russian-flagged vessel and is expected to arrive around midnight (8 a.m. ET) Sunday, the Australian Maritime Safety Authority said.
It follows the Chinese icebreaker Xue Long, or Snow Dragon, which was just six nautical miles away from the trapped vessel when it couldn’t get any closer due to unusually thick ice.

The Snow Dragon went back to open water but remains in the area to provide support, said Andrea Hayward Maher, spokeswoman for the AMSA. The Chinese ship has a helicopter on board that could assist in evacuation.

The plan is to see if the Aurora Australis can break through the ice further than the Chinese ship could.

“If not, the aerial transfer of passengers on board maybe a possibility,” Hayward Maher said.

A French icebreaker was also en route to assist, but AMSA called off that vessel’s mission Saturday after it became clear that ship wouldn’t get farther than the Chinese boat. Also, the French and Chinese ships can break ice only about 1 meter thick, where as the Australian ship can pierce through floe about 1.35 meters thick.

“Some reports say that the ice is at least 2 meters deep. It’s a possibility that the Aurora Australis might not be able to break through that type of ice,” Hayward Maher said.

Extreme conditions

The rescue icebreakers were battling the planet’s coldest environment while trying to reach the Akademik Shokalskiy ship, whose 74 researchers, crew and tourists remained in good condition despite being at a frozen standstill since Monday.

Ship stuck in Antarctica awaits rescue Icebreaker gets stuck; rescue stalled

The ship is carrying scientists and passengers led by expedition leader Chris Tunrey, an Australian professor of climate change.

“The vessel is fine, it’s safe and everyone on board is very well,” Turney said. “Morale is really high.”

The ship got stuck in the ice 15 days after setting out on the second leg of its research trip.

According to Turney, a professor at the University of New South Wales, the ship was surrounded by ice up to nearly 10 feet (3 meters) thick. It was about 100 nautical miles east of the French base Dumont D’Urville, about 1,500 nautical miles south of Hobart, Tasmania.

On Christmas morning, the ship sent a satellite distress signal after conditions failed to clear.

The crew had a “great Christmas” despite their situation, Turney told CNN. He said crew members have used the delay to get more work done. “We’ve just kept the team busy,” he said.

The expedition is trying to update scientific measurements taken by an Australian expedition led by Douglas Mawson that set out in 1911.

The expedition to gauge the effects of climate change on the region began November 27. The second and current leg of the trip started December 8 and was scheduled to conclude with a return to New Zealand on January 4. Turney said the ship should still be back in New Zealand on time.

WATTSUPWITHTHAT UPDATE:

The expedition is being led by Chris Turney, “climate scientist”, who has “set up a carbon refining company called Carbonscape which has developed technology to fix carbon from the atmosphere and make a host of green bi-products, helping reduce greenhouse gas levels.” The purpose of the expedition is “to discover and communicate the environmental changes taking place in the south.”

It seems they found out what the “environmental changes taking place in the south.” are.

From the WUWT sea ice page, Antarctic Sea Ice is more than 2 standard deviations above normal:

According to this sitrep report for one of the rescue vessels, the Aurora Australis the Akademik Shokalskiy is trapped in sea ice in the Commonwealth Bay region of Antarctica.

This is what the current sea ice coverage looks like at the south pole with the approximate ship location marked:

See how the warmists (the real denialists) are behaving as their theory fails. The will never give up much like the black knight in Monty Python.

‘Twas the week before Christmas, when all through the news,
There were reports of record cold, so many were confused.
Told global warming is why we should care,


 And that the point of no return would soon be here.

The children were bombarded with tales of dread,


 While visions of climate disasters were stuck in each little head.


 And mamma in her Prius, and I on my bike,


 To save the planet, got rid of the cars that we like.

When suddenly in the data there arose such a clatter,


 The earth was not warming, what could be the matter?


The warming stopped, as quick as a flash,

 Leaving proponents in sack-cloth, bathing in ash.



For far too common was new-fallen snow,


 More than forecasted, temperatures 0 or below.


 And, what to my wondering eye there appears,


But an uptick in sea ice, and even more polar bears.



With a little old driver, called the PDO,


 I knew in a moment it had to be so.


 Howling like beagles fearing the shame,


AGW pushers called skeptics many a name!


"Now, Denier! now, madman! now neanderthal, you’re lying!


 You’re an idiot! you’re stupid, know nothing, we’re frying!


To the top of the chart! breaking through the temperature wall!


The warmings out of control, it’s frying us all!”

As dry leaves that before the wild hurricane fly,


 This is the worst drought ever, global warming is why.


So up to the IPCC the climate pushers flew,


 With a gravy train of grants, and politics too.

Make economies pay, we need no proof,


 Just keep saying temperatures are going through the roof.


With the media complicit, my head was turning around,


To see the global temperature level off and then come down.



The warming had stopped, in their mouth was their foot,


 Exposing the scam, and making off with the loot.


Readjusting temperatures, from many years back,


 Peddling disinformation to the media pack.

At conferences they would drink and make merry!


 While the deceit grew in a way, that made it quite scary!


 For the tide it had turned, there was cold that would show,


You can’t say it’s warmer, if there’s too much snow.

The cold that was showing led to chattering of teeth,


 As the cycle came full circle, not unlike a wreath.


The face of global warming had become a subject smelly,


Their position as “solid,” as a bowlful of jelly!



Hockey sticks broken, sea ice on the increase,


 I laughed when I heard their excuses not cease.


 Events we all knew were something ahead,


 Were twisted into worst ever, something to dread.

How dare mother nature destroy AGW’s life’s work,


These deniers are as nasty as a Miley Cyrus Twerk.


But the data is there and everyone knows,


The temperatures leveled off while CO2 rose!

So when in the wire, you hear the cold wind whistle,


 The AGW agenda is ready for dismissal.


 So let me exclaim, as this fades out of sight,


 “Happy Christmas to all, and to all a good-night!”

Icecap Note: By the way, the liars at NOAA NCDC proclaimed November to be the warmest ever for the globe with an anomaly of+1.40F. It was not the case in the NASA data set which had it at roughly half that at +0.72F nor in the satellite data bases which had it near +0.4F. It seems every agency of the Obama administration is loose with the facts. Do you believe unemployment is below 7% (oK if you stop counting people who can’t find a job you might get that) or inflation is zero (because they don’t count volatile food and energy which is the lions share of the costs for the low and middle class). NCDC has a version 3.2.2 of its global data set, each version is warmer than the prior, accomplished with additional post 1990 warming and especially cooling prior to the 1950s.  In private industry this is known as creative accounting and often ends up with people in jail. In government, they get to keep their jobs and are likely to see increased funding.  As Steve Goddard notes here, there are no physical mechanisms to explain the changes. A UHI adjustment would be the opposite.

Brian Williams of NBC Obama news network last night proclaimed it the warmest November ever for the globe. Of course you can count on the worthless Weather Channel owned by NBC to parrot that. 

UPDATE: A team of scientists and lawyers have filed an AMICUS BRIEF to the SCOTUS after presenting compelling evidence, arguing that in conclusion:

The “triggering” determination at issue here is at the core of EPA’s current program to restrict hydrocarbon based energy and make it more expensive and less available. The Endangerment Finding and subsequent triggering determination came about when Congress failed to pass President Obama’s proposed “cap and trade” legislation during his first term. As described by the President during his 2008 campaign, that legislation was specifically intended to reduce carbon emissions by forcing a massive increase in the price of energy: “Under my plan ... electricity rates would necessarily skyrocket.” Erica Martinson, Uttered in 2008, Still Haunting Obama in 2012, Politico (Apr. 5, 2012, 11:37 PM), http://www.‌politico.‌com/news/stories/ 0412/74892.html.

Adding CO2 to the stationary source PSD permitting program seeks to accomplish the same result through forcing the massive closure of coal based power plants (a process already well under way) and hindering and delaying the construction and operation of power sources that use the cheapest forms of energy, which are hydrocarbon based energy. And EPA seeks to achieve that result without new legislation, and instead as a supposed interpretation of over 35-year-old legislation never previously thought to cover this subject matter.

Meanwhile the United States is on the cusp of an energy revolution of hydrocarbons from unconventional oil and natural gas sources that is having the effect of rapidly increasing the supply and decreasing the price of carbon-based energy. See, e.g., America’s New Energy Future: The Unconventional Oil and Gas Revolution and the U.S. Economy, Volumes I, II, and III, IHS (September 2013). IHS sees the energy revolution as adding millions of jobs and hundreds of billions of dollars annually to the U.S. economy, all based on burning hydrocarbon fuels and emitting CO2 into the atmosphere. EPA looks upon this prospect with horror, and the stationary source PSD permitting program coupled with EPA’s plans for CO2 emissions standards is precisely the means it sees available to stop it before it can get too far.

Arbitrarily raising the price of energy is the same thing as purposely impoverishing the American people. It is shocking that our government would intentionally pursue such a goal, particularly without any scientific basis whatsoever to do so, as discussed in Point IV above. It is equally shocking that the executive branch, without supporting legislation, would decide that accomplishing its energy/climate goals, not endorsed by Congress or the general public, is so sacrosanct that it must take a completely inapplicable law and twist it into a pretzel in the desperate but ultimately futile effort to find a basis to raise the price and limit the availability of energy for the American people. And meanwhile CO2 is a worldwide phenomenon, and other countries like China and India have no plans meaningfully to curtail their rapidly increasing emissions. Unilateral CO2 emission control by the United States promises to damage the economy of the United States without any benefits.

In fact, increasing CO2 in the atmosphere facilitates achieving the goal of raising the poor out of poverty through increasing food production. CO2 is the primary “food” utilized by the vast majority of plants to produce the organic matter out of which they construct their tissues, which subsequently become the ultimate source of food for nearly all animals and humans. Consequently, the more CO2 there is in the air, the better plants grow, as has been demonstrated in literally thousands of laboratory and field experiments. See Craig Idso & S. Fred Singer, Climate Change Reconsidered: 2009 Report of the Nongovernmental Panel on Climate Change (NIPCC), Chapter 7 (Chicago, IL 2009). And the better plants grow, the more food there is available to sustain the entire biosphere.

At least since the International Conference on Rising Atmospheric Carbon Dioxide and Plant Productivity of 1983, it has been known that a doubling of the air’s CO2 concentration would likely lead to a 50% increase in photosynthesis and a doubling of water use efficiency in many types of plants, as well as significant increases in biological nitrogen fixation in almost all biological systems, and an increase in the ability of plants to adapt to a variety of environmental stresses.

Availability of potable water for irrigation is a key constraint on food production in the United States and many other countries; yet studies conducted on hundreds of different plant species demonstrate the very real and measurable growth- enhancing, water-saving, and stress-alleviating advantages that rising atmospheric CO2 concentrations bestow upon Earth’s plants. See Craig Idso & S. Fred Singer, Climate Change Reconsidered: 2009 Report of the Nongovernmental Panel on Climate Change (NIPCC), Ch. 7 (2009); Craig Idso & Sherwood Idso, The Many Benefits of Atmospheric CO2 Enrichment (2011).

All these benefits largely flow to those who otherwise struggle to afford an adequate supply of food, in other words, the poor. The bottom line here is that rising atmospheric CO2 levels yield very significant net benefits to society. In making its Endangerment Finding, EPA did not even consider these benefits. That total dereliction of duty calls into question the reasonableness of its entire effort to restrict CO2 under the CAA, and ultimately the reasonableness of the so-called “triggering” rule at issue on this petition. This is particularly true given that each of EPA’s three lines of evidence for its Endangerment finding is demonstrably invalid.

If EPA succeeds in limiting the availability of hydrocarbon based energy and raising its price, it is not the rich who will be priced out of purchasing the energy they need. It is the poor. Cheap carbon-based energy from stationary sources means that relatively low income people in this country can afford, for example, to heat, cool and light their homes, cook meals, use the internet, talk on cell phones, buy products like automobiles made of inexpensive steel and other metals. If the lowest cost energy available is unwisely restricted, all Americans will suffer greatly, but the poorest the first and the most.

Indeed to the extent that this Administration can significantly influence other countries’ energy/ climate policy, it is primarily the poor who would stand to be harmed by decreased availability of affordable food resulting from restriction of the amount of CO2 that would otherwise be in the atmosphere. In seeking to regulate CO2 from stationary sources under the CAA, and in opposing the petitions, EPA would enlist this Court in its campaign that results in such impoverishment. It would be very sad if this Court by its decision went along with this campaign.

CONCLUSION

The judgment of the Court of Appeals should be reversed. In addition EPA’s Endangerment Finding should be vacated.

Majority rules on climate science?

Jeff Jacoby, Boston Globe

BACK IN 2006, around the time Al Gore’s global-warming documentary, “An Inconvenient Truth,” was released, I started a file labeled “What Climate Consensus?” Gore was insisting that “the debate among the scientists is over,” and only an ignoramus or a lackey for the fossil-fuel industry could doubt that human beings were headed for a climate catastrophe of their own making. But it didn’t take much sleuthing to discover that there was plenty of debate among scientists about the causes and consequences of global warming. Many experts were skeptical about the hyperbole of alarmists like Gore, and as I came across examples, I added them to my file.

The thicker that file grew, the more shrilly intolerant the alarmists became.

Over and over the True Believers insist that their view is not just widely accepted in the scientific community, but virtually unanimous apart from some crackpots. Rajendra Pachauri, chairman of the UN’s Intergovernmental Panel on Climate Change, has likened doubters to members of a Flat Earth Society. CBS news reporter Scott Pelley, asked why his “60 Minutes” broadcasts on global warming didn’t acknowledge the views of skeptics, reached for an even more wounding comparison: “If I do an interview with Elie Wiesel, am I required as a journalist to find a Holocaust denier?”

It seems to make no difference that those challenging the doomsday narrative include some of the world’s most distinguished scientists, or that numerous experts in climatology and related earth sciences have repeatedly gone public with their critiques. To climate ideologues, they’re invisible. “Ninety-seven percent of scientists agree: #climate change is real, man-made and dangerous,” President Obama tweeted in May.

Really? That’s not what the American Meteorological Society learned from a recent survey of its professional members. Only a bare majority, 52 percent, said that climate change is largely being driven by human activity. Scientists with a “liberal political orientation” were much more likely to regard global warming as human-caused and harmful, the survey’s authors found - in fact, as a predictor of respondents’ views on global warming, ideology outweighed greater expertise. “This would be strong evidence against the idea that expert scientists’ views on politically controversial topics can be completely objective,” the authors observe.

In that light, consider the findings of a new study published in the journal Nature Climate Change. Of 117 global warming predictions generated by climate-model simulations, all but three “significantly” overestimated the actual amount of warming that occurred during the past 20 years. The models typically forecast that global surface temperature would rise by more than twice as much as it did.

Why would so many scientists have relied on models that turned out to be so wrong? The authors propose several plausible explanations - volcanic eruptions? solar irradiation? - but their bottom line is that climate science still has a long way to go: “Ultimately the causes of this inconsistency will only be understood after . . . waiting to see how global temperature responds over the coming decades.”

That understanding won’t be advanced one millimeter by ideologues who thunder that the “science is settled.” Perhaps all those climate models wouldn’t have been programmed to overpredict global warming if the pressure to conform to the alarmists’ view weren’t so pervasive.

In a classic 1955 lecture on “The Value of Science,” the celebrated physicist (and future Nobel laureate) Richard Feynman warned that science would be hobbled if it tried to stifle its doubters and skeptics. “If we want to solve a problem that we have never solved before, we must leave the door to the unknown ajar ... [D]oubt is not to be feared but welcomed and discussed.”

Science isn’t settled by majority vote, and invoking “consensus” to shut off debate is authoritarian and anti-scientific. There are always inconvenient truths to challenge what the majority thinks it knows. Ninety-seven percent of experts may be impressed with the emperor’s new clothes. That’s no reason to silence those who insist the emperor is naked.

CNSNews.com) The number of Americans who think “dealing with global climate change” should be a top U.S. foreign policy goal continues to fall in a poll that has tracked the issue since the 1990s, and five years under an administration more inclined to make it an issue does not appear to have stemmed the slide.

The latest Pew Research Center poll surveying Americans’ foreign policy goals also found a significant partisan difference when it comes to the importance of prioritizing climate change.

Out of 11 foreign policy goals featured in the poll released Wednesday, climate change ranks fourth from the bottom, with 37 percent of respondents saying it should be a top priority. That has dropped slowly but steadily from 50 percent in 1997, to 44 in 2001, 43 in 2005 and 40 in 2009.

Of the other goals, “protecting U.S. from terrorist attacks” and “protecting U.S. jobs” get the most support, at 83 and 81 percent respectively, while “promoting democracy in other nations” gets the least, at 18 percent.

Unlike the climate change goal’s downward movement, most of the others have risen and fallen in importance at various times over the years of polling, although “reducing dependence on imported energy” has dropped since 2005 (from 67 to 61 percent) and “promoting democracy in other nations,” after climbing from 1997 to 2001 (from 22 to 29 percent), has dropped steadily ever since.

The other goals featured are “preventing the spread of weapons of mass destruction” (73 percent in 2013) “combating international drug trafficking” (57 percent), “reducing illegal immigration” (48 percent), “strengthening the United Nations” (37 percent), “promoting and defending human rights in other countries” (33 percent) and “helping improve living standards in developing nations” (23 percent).

Pew also tracked the differences between Republicans’ and Democrats’ views on the 11 foreign policy goals, and found that the widest gap - a difference of 41 points applies to climate change: Fifty-seven percent of Democrats, and only 16 percent of Republicans, believe it should be a U.S. foreign policy priority.

The next biggest partisan gaps relate to strengthening the U.N. (50 percent Democrats vs. 25 percent Republicans) and illegal immigration (62 percent Republicans vs. 38 percent Democrats).

An earlier Pew poll found that Republicans associated with the tea party account for most of the skepticism about global warming: Just 25 percent of tea party Republicans agreed there was “solid evidence the earth is warming” compared to 61 percent of non-tea party Republicans. Eighty-four percent of Democrats shared that belief.

But even among the non-tea party Republican respondents in that survey, only 32 percent said human activity was to blame, while 24 percent attributed warming to “natural patterns.”

Overall, fewer than half of the respondents of all political persuasions (44 percent) believed human activity is to blame.

The continuing downward trend in prioritizing climate change in foreign policy comes despite the fact that President Obama has, in the words of Secretary of State John Kerry, placed the issue “back on the front burner where it belongs.”

Attributing climate change to human activity is a view strongly held by senior administration officials. Kerry himself, who as a senator was an outspoken advocate, has prioritized the issue of human-induced global warming as America’s top diplomat. He recently declared himself “amazed” that some Americans do not recognize the urgency of climate change “for life itself on the planet as we know it.”

His predecessor at the State Department, Hillary Clinton, said in May 2011, “there is no doubt, except among those who are into denying the facts before their eyes, that climate change is occurring, and it is contributed to by human actions at every level.”

In its most recent report, released last September, the U.N. Intergovernmental Panel on Climate Change (IPCC) concluded that global warming is “unequivocal” and that it is “extremely likely” that human activity has been the main cause.

That was stronger language than appeared in the IPCC’s previous report, in 2007, which asserted that global warming was “very likely” man-made.

A year ago, a peer-reviewed journal published the results of a survey of more than 1,000 professional engineers’ and geoscientists’ views on climate change, and found that only 36 percent fitted into a group that “express[ed] the strong belief that climate change is happening, that it is not a normal cycle of nature, and humans are the main or central cause.”

“They are the only group to see the scientific debate as mostly settled and the IPCC modeling to be accurate,” the survey found.

The rest of the respondents, with slight variations, expressed varying degrees of skepticism about the causes of climate change, the extent of risk it poses, and the accuracy of IPCC modeling.

The believers, members of the Church of Climate Scientology of course tend not to pay any attention actual data but believe their idealogue leaders, the models and their all too compliant leftist media. You can usually pick them out at the beach.

The debate on the social cost of carbon is heating up.

White House

The White House has recently issued a Technical Support Document on the Social Cost of Carbon [link.  Excerpts from the Executive Summary:

The purpose of the “social cost of carbon” (SCC) estimates presented here is to allow agencies to incorporate the social benefits of reducing carbon dioxide (CO2) emissions into cost-benefit analyses of regulatory actions that impact cumulative global emissions. The SCC is an estimate of the monetized damages associated with an incremental increase in carbon emissions in a given year. It is intended to include (but is not limited to) changes in net agricultural productivity, human health, property damages from increased flood risk, and the value of ecosystem services due to climate change.

The SCC estimates using the updated versions of the models are higher than those reported in the 2010 TSD. By way of comparison, the four 2020 SCC estimates reported in the 2010 TSD were $7, $26, $42 and $81 (2007$). The corresponding four updated SCC estimates for 2020 are $12, $43, $65, and $129 (2007$). The model updates that are relevant to the SCC estimates include: an explicit representation of sea level rise damages in the DICE and PAGE models; updated adaptation assumptions, revisions to ensure damages are constrained by GDP, updated regional scaling of damages, and a revised treatment of potentially abrupt shifts in climate damages in the PAGE model; an updated carbon cycle in the DICE model; and updated damage functions for sea level rise impacts, the agricultural sector, and reduced space heating requirements, as well as changes to the transient response of temperature to the buildup of GHG concentrations and the inclusion of indirect effects of methane emissions in the FUND model.

The Hill

The controversy surrounding this issue is reported today in a post by The Hill.  Excerpts:

The White House will seek new public comment on the “social cost of carbon” (SCC), a metric that helps regulators estimate the benefits of rules that cut greenhouse gas emissions.

The Office of Management and Budget (OMB) decision arrives amid criticism from industry groups and Republicans who say the Obama administration’s May 2013 upward revision of the SCC earlier lacked public input.
The “social cost of carbon” has lately been a flashpoint in wider political and lobbying battles over White House’s climate change policy, especially planned Environmental Protection Agency carbon standards for power plants.
Howard Shelanski, the top White House regulatory official, said in a blog post late Friday afternoon that the administration was making new changes to the estimate, and would launch a public comment period “in response to public and stakeholder interest.”

Business groups, such as the Chamber of Commerce and the American Petroleum Institute, have been challenging the revised estimate on various fronts.

In addition, the GOP-led House recently passed a bill that would prevent the EPA from using the metric in major energy rules.

Background info

The Yale Forum on Climate Change has a good post SCC, Social Costs of Carbon: Continuing a little told story.  This article provides a lot of good background information. Another good background post is at CSIS.

Dr. Craig Idso

Opposing view points

The SPPI takes a different approach to this issue, looking at The Positive Externalities of CO2.  Excerpt:

It is clear from the material presented in this report that the modern rise in the air’s CO2 content is providing a tremendous economic benefit to global crop production.

The very real positive externality of inadvertent atmospheric CO2 enrichment must be considered in all studies examining the SCC; and its observationally-deduced effects must be given premier weighting over the speculative negative externalities presumed to occur in computer model projections of global warming. Until that time, little if any weight should be placed on current SCC calculations..

Another contrary view is provided by Media Matters WSJ Contradicts Experts on Social Cost of Carbon.  Punchline:

WSJ Editorial Suggests There Should Be No Social Cost Of Carbon. In an editorial, The Wall Street Journal criticized the Obama administration for raising the social cost of carbon, or the estimate of the damages caused by emitting a ton of carbon dioxide in one year, which is used by regulatory agencies to calculate the benefit of reducing carbon emissions.The Journal suggested that the social cost of carbon should be $0, approvingly citing the previous lack of a social cost for carbon, adding that “Congress has never legislated that there are social costs to carbon emissions” and claiming that assigning such as cost is an “inventio[n]” to “ri[g] the rule-making”:

JC comment:  The bottom line seems to be that SCC is being established as a surrogate for a National Carbon Tax.  My reaction to all this is that it seems like the uncertainty in SCC is colossal, I am not convinced that we should even have confidence in the sign of the SCC in light of the SPPI and WSJ analyses.  And the White House is presenting values of SCC with two significant figures?  Uncertain T. Monster is not pleased.  There has been no attempt to propagate uncertainty through the FUND, DICE and PAGE models, not to mention whatever front end assumptions about carbon and climate are being used as inputs.

And even if we did have confidence in the SCC numbers, the policies evolving around the SCC seem quite convoluted and who knows how they would even play out at achieving the larger policy objectives.

And finally, I return to the issues raised in the preceding post, 20 tips for interpreting scientific claims.  Some commenters seemed to think this was pretty much kindergarten stuff and of course policy makers (or their staffers) understand this stuff.  Well anyone taking seriously the White House’s SCC numbers needs to go back to kindergarten and pay attention to the 20 tips.

In light of the importance of SCC to U.S. climate/energy policy, it seems that much more attention needs to be paid to this issue.
