Global Lukewarming? Update: Norwegian Study Not Peer Reviewed

Last week the Research Council of Norway announced the results of a new assessment of the climate system’s “sensitivity” taking into account the leveling off of global temperatures during the decade from 2000 to 2010. The study projects that a doubling of atmospheric carbon dioxide (CO2) concentrations over pre-industrial levels will increase global temperatures by between 1.2°C and 2.9°C, with 1.9°C being the most likely outcome. That is considerably cooler than the UN IPCC Fourth Assessment Report (AR4) estimate of 2°C to 4.5°C, with 3°C as the most probable outcome.

Climate sensitivity is an estimate of how much warming results from a given increase in CO2 concentrations. Estimates typically project the amount of warming from a doubling of CO2 concentrations over the pre-industrial (year 1750) level of 280 parts per million (ppm). At the current rate of increase (about 2 ppm/yr), a doubling to 560 ppm is expected by mid-century.

Climate alarm depends on several gloomy assumptions — about how fast emissions will increase, how fast atmospheric concentrations will rise, how much global temperatures will rise, how warming will affect ice sheet dynamics and sea-level rise, how warming will affect weather patterns, how the latter will affect agriculture and other economic activities, and how all climate change impacts will affect public health and welfare. But the chief assumption is the range of projected warming from a doubling of CO2 concentrations — the sensitivity estimate.

When the reseachers at the Center for International Climate and Environmental Research – Oslo (CICERO) applied their computer “model and statistics to analyse temperature readings from the air and ocean for the period ending in 2000, they found that climate sensitivity to a doubling of atmospheric CO2 concentration will most likely be 3.7°C, which is somewhat higher than the IPCC prognosis.” However, ”when they entered temperatures and other data from the decade 2000-2010 into the model, climate sensitivity was greatly reduced to a ‘mere’ 1.9°C.”

Referring to the IPCC AR4 warming forecasts, project manager Terje Berntsen, a geoscience professor at the University of Oslo, commented: “The Earth’s mean temperature rose sharply during the 1990s. This may have caused us to overestimate climate sensitivity.”

No single study can make a dent on the self-anointed “scientific consensus.” But the Norwegian study is one among several recent studies that call into question the IPCC sensitivity assumptions. Cato Institute climatologist Patrick Michaels recently summarized a partial list of such studies in Forbes magazine: [click to continue…]

Sen. Whitehouse vs the ‘Deniers’ – Addendum on Ocean Acidification

Post image for Sen. Whitehouse vs the ‘Deniers’ – Addendum on Ocean Acidification

As discussed in an earlier post, Sen. Sheldon Whitehouse (D-R.I.) took to the Senate floor in December last year to lash out at climate ‘deniers.’ Among other allegations, Whitehouse said “deniers tend to ignore facts they can’t explain away.” He cites “the increasing acidification of the oceans,” which ”is simple to measure and undeniably, chemically linked to carbon concentrations in the atmosphere. So we hear nothing about ocean acidification from the deniers,” he claims. Not so, I explained.

Prominent skeptics Patrick Michaels and Chip Knappenberger of the Cato Institute discussed the subject on their old blog, World Climate Report. Another leading skeptical Web site, CO2Science.Org, maintains an ocean acidification database, and the researchers – Drs. Craig, Sherwood, and Keith Idso – review another scientific paper on acidification just about every week. My earlier post concluded: “They don’t share Sen. Whitehouse’s alarm about ocean acidification, but they do not ignore it. The Senator should check his facts before casting aspersions.”

It’s a familiar pattern. Al Gore would have us believe that if we acknowledge the reality of anthropogenic global warming, then we must also believe in his ”planetary emergency” and embrace his policy agenda as a moral imperative. Similarly, the Gorethodox would have us believe that if CO2 emissions make sea water slightly more acidic (actually, slightly less basic), then corals and other calcifying organisms are headed for disaster and, again, we have a moral imperative to stop mountaintop coal mining, block the Keystone XL pipeline, etc.

Here I’d like to reproduce in full the Idsos’ latest review of an ocean acidification study, because it clearly demonstrates the difference between facts and alarmist interpretations of facts.

Background
Ocean acidification is considered by climate alarmists to be detrimental to nearly all sea creatures; and the early life-stages of these organisms are generally thought to be the most sensitive stages to this environmental change.

What was done
In a study designed to explore these assumptions, the authors tested the effects of seawater acidification by CO2 addition, leading to reductions of 0.3 and 0.6 pH units, on six-month-old juvenile mussels (Mytilus galloprovincialis), which they obtained from a mussel raft on the Ria de Ares-Betanzos of Northwest Spain, focusing their attention on growth, calcification and mortality.

EU Still Groping for Carbon Price Sweet Spot

Post image for EU Still Groping for Carbon Price Sweet Spot

In a post last September, I observed that carbon prices in the EU’s emission trading system (ETS) were so low they failed to incentivize hoped-for technology innovation, yet so high EU governments had to establish a “carbon compensation fund” to keep manufacturers from offshoring their operations. At the time, Reuters reported, permit prices for December had fallen to €7.74 ($9.98) per ton.

Thurdsay’s Financial Times (registration required) reports that EU carbon prices crashed this week to a record low of €2.81 ($3.79) per ton, recovering slightly to €4.41 per ton. The FT observes that carbon permits “have lost 85 per cent of their value from mid-2011 as economic weakness has exacerbated the glut in supply.”

Once again traders and EU officials fret that carbon prices are too low to spur investment in ‘green’ technologies. But there’s a new wrinkle. During most of its history, the ETS was mainly a system of free permit allocations to covered entities. Critics complained that big energy producers reaped windfall profits at the expense of manufacturers and consumers. Their proposed cure was to auction most allowances and make ‘polluters’ pay. Yet the collapse of carbon prices is partly due to “a new system introduced this month to auction allowances,” which has added “millions more allowances . . . to an already oversupplied market each week.”

The one thing you can take to the bank is that the collapse of carbon prices will induce none of the EU firms receiving millions of Euros from the carbon compensation fund to return any of the money to taxpayers.

President Obama’s Inaugural Speech: New Heat on Warming?

Post image for President Obama’s Inaugural Speech: New Heat on Warming?

President Obama’s second inaugural speech featured climate change more prominently than did his first inaugural address. As Greenwire (subscription required) observed:

Gone was Obama’s roundabout reference to climate change through “the specter of a warming planet” from four years ago. This time, the president put the issue front and center.

Will that make any difference legislatively? Probably not. In the House, Republicans opposed to cap-and-trade, EPA regulation of greenhouse gases (GHGs), and carbon taxes are still in charge.

Is the President’s renewed emphasis on climate change just a sop to his environmentalist base? Doubtful. As a second termer, Obama has less reason politically to restrain his ‘progressive’ impulses. Several regulatory options are now in play:

  • The Department of Interior could list more species as threatened or endangered based on climate change concerns.
  • The President could finally veto the Keystone XL pipeline — a key objective of the climate alarm movement.
  • The EPA could issue GHG performance standards for existing (as distinct from new or modified) coal power plants, as well as GHG performance standards for other industrial categories (refineries, cement production facilities, steel mills, paper mills, etc.).
  • The EPA could finally act on petitions pending from the Bush administration to set GHG emission standards for marine vessels, aircraft, and non-road vehicles.
  • The EPA could finally act on a December 2009 petition by the Center for Biological Diversity and 350.Org to establish national ambient air quality standards (NAAQS) for carbon dioxide (CO2) and other GHGs.

I’ll make one prediction: If Obama does not veto the Keystone XL Pipeline after talking the talk on climate change, green groups will go ballistic (even though, Cato Institute scholar Chip Knappenberger calculates, full-throttle operation of the Keystone XL Pipeline would add an inconsequential 0.0001°C/yr to global temperatures). My colleague Myron Ebell reasonably speculates that Obama’s tough talk on climate was a signal to green groups to organize the biggest anti-Keystone protest ever.

Now let’s examine the climate change segment of Obama’s inaugural speech: [click to continue…]

Climate Change Impacts in the U.S.: Sober Analysis, Cool Graphics from Patrick Michaels and Chip Knappenberger

Cato Institute scholars Patrick Michaels and Chip Knappenberger have produced a layman-friendly yet thoroughly referenced draft report summarizing “the important science that is missing from Global Climate Change Impacts in the United States,” a U.S. Government document underpinning the EPA’s December 2009 endangerment rule, the foundation of all of the agency’s greenhouse gas (GHG) regulations.

Pat and Chip’s draft report, titled Addendum: Climate Change Impacts in the United States, is a sober antidote to the climate fear-mongering patronized by the Obama administration, mainstream media, the U.N., corporate rent seekers, and the green movement. Among the best features are the numerous graphics, some of which I will post here.

Taking these in no particular order, let’s begin with the scariest part of Al Gore’s “planetary emergency”: sea-level rise. Is the rate of sea-level rise dangerously accelerating? No. Over the 20th century, there was considerable decadal variation in the rate of sea-level rise but no long-term trend.

Ethanol Litigation: Another Powerful Dissent by Judge Kavanaugh

Post image for Ethanol Litigation: Another Powerful Dissent by Judge Kavanaugh

On Tuesday, the D.C. Circuit Court of Appeals denied by 7-1 a petition for a full-court re-hearing of its 2-1 decision last summer to dismiss litigation challenging EPA’s approval of the sale of E15 at retail motor fuel pumps. E15 is a blend of 85% gasoline and 15% ethanol.

In both decisions, Judge Brett Kavanaugh was the sole dissenter, and both times he trounces the majority on the facts and statutory logic.

In a previous post, I reviewed Kavanaugh’s dissent in the August 2012 decision. Herewith a brief recap:

  • The 2-1 majority held that petitioners – refiners and livestock producers — would not be injured by the EPA’s grant of a waiver authorizing the sale of E15 and thus lack standing to challenge the agency. The majority somehow missed the obvious.
  • There being no commercial substitute for ethanol to meet the ever-increasing production quota established by the Renewable Fuel Standard (RFS), EPA approval of E15 is a de facto mandate on refiners to increase the blend from E10 to E15 — a roughly 50% increase from about 14 billion gallons to 21 billion gallons annually. That will necessarily impose a cost on refiners. 
  • In addition, because virtually all U.S. ethanol is made from corn, approving E15 will increase the demand for and price of corn, imposing a cost on livestock producers, who purchase billions of bushels annually to feed their hogs, cattle, and poultry.
  • Clearly, EPA approval of E15 injures both petitioner groups, so the Court should have reviewed the petitions on the merits.
  • Section 211(f) of the Clean Air Act (CAA) prohibits the EPA from approving the sale of any fuel additive that causes or contributes to the failure of emission control systems in any vehicle manufactured after 1974. 
  • By the EPA’s own admission, E15 can contribute to emission control failures in vehicles manufactured during model years 1975 through 2000.
  • Therefore, the EPA lacks authority to approve the sale of E15.

Kavanaugh’s dissent in Tuesday’s decision reiterates those points but also adds some illuminating refinements. [click to continue…]

One Million Fewer Jobs Created by 2016 under ‘Modest’ Carbon Tax

Heritage Foundation economists David Kreutzer and Nicolas Loris have posted an assessment of the economic impacts of a carbon tax that starts out at $25 per ton and increases by 5% annually (after adjusting for inflation). Rather than use industry data or assumptions, they compare two policy scenarios (“side cases”) from the U.S. Energy Information Administration’s (EIA) Annual Energy Outlook 2012.

Specifically, Kreutzer and Loris compare projected household income, utility bills, gasoline prices, and job creation in the $25 per ton carbon tax side case and the no-greenhouse-gas-concern side case, a scenario in which energy investors face no risk of a carbon tax or greenhouse gas (GHG) regulation.  

Here’s what they found. A ‘modest’ carbon tax, as described above, would:

  • Cut the income of a family of four by $1,900 per year in 2016 and lead to average losses of $1,400 per year through 2035;
  • Raise the family-of-four energy bill by more than $500 per year (not counting the cost of gasoline);
  • Cause gasoline prices to increase by up to $0.50 gallon, or by 10 percent on an average gallon price; and
  • Lead to an aggregate loss of more than 1 million jobs by 2016 alone. [click to continue…]

How Many ‘Wedges’ Does It Take to Solve the Climate ‘Problem’?

In An Inconvenient Truth (pp. 280-281), Al Gore enthused about a Science magazine study by Princeton economists Robert Socolow and Stephen Pacala. The study concluded that, “Humanity already possesses the fundamental scientific, technical, and industrial know how to solve the carbon and climate problems for the next half century.” Gore claimed the policies Socolow and Pacala recommend, “all of which are based on already-existing, affordable technologies,” could reduce emissions below 1970s levels.

But Gore could not know the solutions are “affordable,” because the authors did not attempt to estimate costs. The study basically shows that if political leaders can somehow coerce everybody to use less energy and adopt low- or zero-carbon energy technologies regardless of cost, they can significantly reduce emissions by 2054. We needed Princeton professors to tell us that?

If An Inconvenient Truth were a balanced presentation rather than a CGI-embellished lawyer’s brief, Gore would have mentioned that Socolow and Pacala’s (S&P) study was a response to an earlier analysis, also published in Science, by New York University Prof. Martin Hoffert and 17 colleagues.

Hoffert et al. found that all existing energy technologies “have severe deficiencies that limit their ability to stabilize global climate.” They specificially took issue with the UN IPCC’s claim that “known technological options” could stabilize atmospheric carbon dioxide (CO2) levels at 550 parts per million (ppm) or even 450 ppm over the next 100 years. Noting that world energy demand could triple by 2050, they found that zero-carbon technologies that can produce 100 to 300% of present world power consumption “do not exist operationally or as pilot plants.” Bottom line: “CO2 is a combustion byproduct vital to how civilization is powered; it cannot be regulated away.” They concluded that it is not possible to stabilize atmospheric CO2 concentrations and meet global energy needs “without drastic technological breakthroughs.”

I review this ancient history because Environmental Research Letters just published a study ‘updating’ (i.e. rebutting) the S&P analysis. The lead author is UC Irvine Prof. Steven Davis. One of three other co-authors is Martin Hoffert.

S&P estimated that seven ”stabilization wedges” could limit atmospheric CO2 concentrations to 500 ppm by 2054. The Davis team estimates it will take 19 and possibly 31 wedges to solve the climate ‘problem.’ In other words, the challenge is much more difficult than S&P believed.

But what, you may be wondering, is a “stabilization wedge”?

Will the Supreme Court Review EPA’s Greenhouse Gas Regulations? Part II

In Coalition for Responsible Regulation v. EPA, petitioners — a coalition of industry groups, states, and non-profit organizations — sought to overturn the EPA’s endangerment, tailpipe, triggering, and tailoring rules for greenhouse gases (GHGs). In June of last year, a three-judge panel of the D.C. Circuit Court of Appeals ruled in favor of the EPA, upholding the four GHG rules. In August, coalition members petitioned for an en banc (full court) rehearing of the case. On Dec. 20, 2012 the D.C. Circuit Court of Appeals rejected the petitions by 5-2.

However, given the importance of the issues and the strength of the two dissenting opinions, the case may go to the Supreme Court. Last week, I reviewed Judge Janice Rogers Brown’s dissenting opinion. Today, I review Judge Brett Kavanaugh’s dissent.

Judge Brown chiefly addresses the “interpretative shortcomings” of the Mass. v. EPA Supreme Court decision, which authorized the EPA to regulate GHGs via the Clean Air Act (CAA). Kavanaugh directs his fire at the opinion, shared by the EPA and the five-judge majority, that the CAA’s Prevention of Significant Deterioration (PSD) preconstruction permitting program applies to GHGs, and at the agency’s attempt to “tailor” away the consequent “absurd results” by rewriting the statute.

Will the Supreme Court Review EPA’s Greenhouse Gas Regulations?

Post image for Will the Supreme Court Review EPA’s Greenhouse Gas Regulations?

Powerful dissenting opinions can sometimes persuade a higher court to review a lower court’s ruling. Massachusetts v. EPA (2007), the Supreme Court decision empowering the EPA to act as a super legislature and ‘enact’ climate policy, is a prime example.

In 2005, the D.C. Circuit Court of Appeals held that the Bush administration EPA properly exercised its discretion when it denied a petition by eco-litigation groups to regulate greenhouse gas (GHG) emissions from new motor vehicles under §202 of the Clean Air Act (CAA). I remember feeling relieved but disappointed. The 2-1 majority ducked the central issue, namely, whether the CAA authorizes the EPA to regulate GHGs as climate change agents. In contrast, Judge David Tatel’s dissent made a strong argument that the EPA does have the power to regulate GHGs and, consequently, has a duty to determine whether GHG emissions endanger public health or welfare. Tatel’s opinion was a key factor persuading the Supreme Court to hear the case.

The Court in Massachusetts ruled in favor of petitioners, setting the stage for the EPA’s ongoing, ever-expanding regulation of GHG emissions from both mobile and stationary sources.

The EPA’s greenhouse regulatory surge, however, is not yet ‘settled law.’ Recent strong dissenting opinions by two D.C. Circuit Court of Appeals judges may persuade the Supreme Court to review one or more of the agency’s GHG rules — or even reassess its ruling in Mass. v. EPA. [click to continue…]
