Post image for Satellite Observations Validate Model Predictions — CO2 Emissions Are Greening the Earth!

I’m going to have to revise my skepticism about climate models. In at least one respect, their projections are spot on accurate. Satellite observations apparently validate model predictions that carbon dioxide (CO2) emissions will green the Earth.

That’s what four Australian scientists report in “Impact of CO2 fertilization on maximum foliage cover across the globe’s warm, arid environments,” a study published in Geophysical Research Letters.

Models project that the 14% increase in atmospheric CO2 concentration from 1982 to 2010 would increase green foliage in warm, arid environments by 5-10%, and lo, satellites reveal an 11% increase that cannot be accounted for by other known factors.

As the researchers explain in the study’s abstract:

Satellite observations reveal a greening of the globe over recent decades. The role in this greening of the “CO2 fertilization” effect—the enhancement of photosynthesis due to rising CO2 levels—is yet to be established. The direct CO2 effect on vegetation should be most clearly expressed in warm, arid environments where water is the dominant limit to vegetation growth. Using gas exchange theory, we predict that the 14% increase in atmospheric CO2 (1982–2010) led to a 5 to 10% increase in green foliage cover in warm, arid environments. Satellite observations, analyzed to remove the effect of variations in precipitation, show that cover across these environments has increased by 11%. Our results confirm that the anticipated CO2 fertilization effect is occurring alongside ongoing anthropogenic perturbations to the carbon cycle and that the fertilization effect is now a significant land surface process.

Post image for Global Warming: Planet’s Most Hyped Problem

Last week, National Journal’s Energy Insiders blog hosted a discussion on the question: “Is Global Warming the Planet’s Biggest Problem?” The blog has been experiencing technical difficulties, and several posts, including mine, are invisible (though they still exist on some server somewhere). So I have decided to repost my contribution here.

* * * * *

Is global warming the planet’s biggest problem? Not even close.

Globally, poverty is by far the leading cause of preventable disease and premature death, and will likely remain so for decades to come.

The World Health Organization is hardly a hotbed of climate skepticism. Nonetheless, climate change ranks near the bottom of the WHO’s list of global health risk factors, well behind “mundane” problems like indoor air pollution, waterborne disease, and vitamin A deficiency, notes economist Indur Goklany. Global warming remains low in the ranking, Goklany finds, even if one accepts the UK Government’s climate impact assessments that informed the alarmist Stern Review.

Other problems that arguably pose greater threats to the health and welfare of millions include nuclear proliferation, uncontrolled entitlement spending, and tyrannical governments.

Al Gore and many other influential people claim global warming is “a planetary emergency – a crisis that threatens the survival of civilization and the habitability of the Earth.”

That is correct, however, only if one or more of their favorite doomsday scenarios is credible. Let’s examine the evidence.

In the mid-2000s, Gore and other pundits warned that the Atlantic Meridional Overturning Circulation (AMOC) could collapse, plunging Europe into an ice age, with all manner of terrible repercussions for the global economy and international stability. The AMOC is the oceanic “conveyor belt” that pulls warm water up from the equator to Northern Europe. In this scenario, melt water from the Greenland ice sheet so decreases the salinity (density) of North Atlantic surface water that it no longer sinks fast enough to drive the AMOC. A Pentagon-commissioned study on abrupt climate change gave credibility to this warming-causes-cooling scare. Climate activists were jubilant: ‘Even the generals are worried!’

The scenario rests on two assumptions: (1) the AMOC is chiefly responsible for Europe’s comparatively mild winters; (2) global warming is melting enough Greenland ice to shut down the AMOC. The first assumption is dubious, the second is highly implausible.

Richard Seager of Columbia University’s Lamont-Doherty Earth Observatory and colleagues found that the chief factor making England 15-20°F warmer in January than comparable latitudes in North America is not maritime heat transport via the AMOC but the very different prevailing winds that blow across northeastern North America and Western Europe. During the winter, “South-westerlies bring warm maritime air into Europe and north-westerlies bring frigid continental air into north-eastern North America.” Thus, Europe should continue to enjoy mild winters even if global warming weakens the AMOC.

Post image for IPCC Cancels Planetary Emergency

Okay, the Intergovernmental Panel on Climate Change does not do so in as many words. But in addition to being more confident than ever (despite a 16-year pause in warming and the growing mismatch between model projections and observations) that most recent warming is man-made, they are also more confident nothing really bad is going to happen during the 21st Century.

The scariest parts of the “planetary emergency” narrative popularized by Al Gore and other pundits are Atlantic Ocean circulation shutdown (implausibly plunging Europe into a mini-ice age), ice sheet disintegration raising sea levels 20 feet, and runaway warming from melting frozen methane deposits.

As BishopHill and Judith Curry report on their separate blogs, IPCC now believes that in the 21st Century, Atlantic Ocean circulation collapse is “very unlikely,” ice sheet collapse is “exceptionally unlikely,” and catastrophic release of methane hydrates from melting permafrost is “very unlikely.” You can read it for yourself in Chapter 12 Table 12.4 of the IPCC’s forthcoming Fifth Assessment Report.

But these doomsday scenarios have always been way more fiction than science. For some time now, extreme weather has been the only card left in the climate alarm deck. Climate activists repeatedly assert that severe droughts, floods, and storms (Hurricane Sandy is their current poster child) are now the “new normal,” and they blame fossil fuels.

On their respective blogs Anthony Watts and Roger Pielke, Jr. provide excerpts about extreme weather from Chapter 2 of the IPCC report. Among the findings:

  • “Current datasets indicate no significant observed trends in global tropical cyclone frequency over the past century … No robust trends in annual numbers of tropical storms, hurricanes and major hurricanes counts have been identified over the past 100 years in the North Atlantic basin.”
  • “In summary, there continues to be a lack of evidence and thus low confidence regarding the sign of trend in the magnitude and/or frequency of floods on a global scale.”
  • “In summary, there is low confidence in observed trends in small-scale severe weather phenomena such as hail and thunderstorms because of historical data inhomogeneities and inadequacies in monitoring systems.”
  • “Based on updated studies, AR4 [the IPCC 2007 report] conclusions regarding global increasing trends in drought since the 1970s were probably overstated.”
  • “In summary, confidence in large scale changes in the intensity of extreme extra-tropical cyclones since 1900 is low.”

Post image for Inspector General Satisfied After EPA Claims Innocence

Investigations usually bring to mind a picture of an in-depth collection of physical and tangible evidence, questioning of witnesses, cross-referencing those witnesses, and asking more questions to reach some conclusion about a past event to determine whether wrongdoing occurred. If a person accused of a crime claimed he was innocent, no reasonable and unbiased sleuth would stop his investigations based upon this admission alone. Unfortunately, such due diligence is not what the Inspector General undertook for its investigation of EPA’s use of secondary email accounts. The IG’s report concludes:

We found no evidence to support that the EPA used, promoted, or encouraged the use of private email accounts to circumvent records management responsibilities. Furthermore, EPA senior officials indicated that they were aware of the agency records management policies and, based only on discussions with these senior officials, the OIG found no evidence that these individuals had used private or alias  email to circumvent federal recordkeeping responsibilities.

For those unfamiliar with the ongoing saga, CEI Fellow Chris Horner, after conducting extensive research for his book, discovered a secondary email account for former EPA administrator Lisa Jackson – the birth of the so-called “Richard Windsor” scandal. The existence of this email prompted the question: Why would the EPA administrator have a secondary email account if not to hide information from the federal record? Moreover, having requested to see the contents of the private emails through the FOIA process, why has the government continued to hide information from the public through copious redaction?

If the EPA is telling the truth about its activities, then why does it continue to stonewall serious investigation attempts? The kind of investigation which relies on hard evidence and not just the word of the accused.

The analysis below subjects EPA’s proposed Carbon Pollution Standard to the D.C. Circuit Court’s rigorous standard of review under Clean Air Act Section 111. Previously, I explained how EPA’s proposed standard, whose purpose is to reduce greenhouse gases, is likely to increase greenhouse gas emissions in practice.

William Yeatman – Legal Analysis of EPA Carbon Pollution Standard by Competitive Enterprise Institute

New studies are raising doubts about the reliability of climate model forecasts. As far back as the 1970s, most climate models have anticipated a decline in Antarctic sea ice. However, instead of declining, Antarctic sea ice in 2013 has approached record levels not seen since the 1970s. Scientists are scrambling to find explanations for this anomaly, but one thing is clear – model projections are facing a crisis of credibility.  If actual conditions diverge from the predicted, then how can we trust the predictions? It seems we are as likely to arrive to the truth about the Earth’s future climate using models as we are from reading tea leaves or performing an augury to pagan gods.

In order to salvage their credibility, scientists have sought a variable to explain away the errors of their models – increased polar winds. According to a new study, increased polar winds have offset the effect of rising temperatures. Adjusting for higher polar winds, models were able to account for 80 percent of the increase in Antarctic ice cover. The author of the study, Dr. Jinlun Zhang, an Oceanographer at the University of Washington, describes the results:

“The polar vortex that swirls around the South Pole is not just stronger than it was when satellite records began in the 1970s, it has more convergence, meaning it shoves the sea ice together to cause ridging. Stronger winds also drive ice faster, which leads to still more deformation and ridging. This creates thicker, longer-lasting ice, while exposing surrounding water and thin ice to the blistering cold winds that cause more ice growth

While higher winds could be driving the increase in polar ice, the remaining 20 percent of the increase remains unaccounted. This suggests some other factor, or combination of factors, might be driving the decrease. Moreover, scientists admit they are uncertain why the models did not anticipate the increase in polar wind. Thus, the explanation for the model error is based on the admission the models were wrong about polar wind speed. If the models were wrong about polar wind speed, then criticism about model reliability still stands.

Accepting this explanation, however, raises another problem. According to the U.S. National Snow and Ice Cover Data Center, previous studies suggest increases in polar wind speed lead to a faster rate of sea ice melt. How can the wind both increase and decrease the extent of ice?

It is clear that models must be taken with a grain of salt. Scientists are often uncertain about the exact cause of long-term changes in the Earth’s climate. Numerous variables should be considered. As Zhang notes in the study,

Still unknown is why the southern winds have been getting stronger. Some scientists have theorized that it could be related to global warming, or to the ozone depletion in the Southern Hemisphere, or just to natural cycles of variability.

Post image for Climate Models vs. Observations: Picture Worth a Thousand Words (thank you Bjorn Lomborg)

Bjorn Lomborg has an excellent column today on the forthcoming (extensively leaked) IPCC Fifth Assessment Report on climate science.

Especially valuable is Lomborg’s chart based on a commentary (“Overestimated global warming over the past 20 years“) published in the monthly journal Nature Climate Change.

Lomborg, Gaps between models and observations

Lomborg comments:

Compared to the actual temperature rise since 1980, the average of 32 top climate models (the so-called CIMP5) overestimates it by 71-159%. A new Nature Climate Change study shows that the prevailing climate models produced estimates that overshot the temperature rise of the last 15 years by more than 300%.

 

The Obama administration’s major new plan to reduce carbon dioxide emissions appears to have a major flaw: It would increase carbon dioxide emissions.

Talk about an unintended consequence!

Last Friday, EPA proposed a regulation, known as the Carbon Pollution Standard, which would require partial carbon capture and sequestration (CCS) at all new coal-fired power plants. In fact, it is highly debatable whether CCS can actually be achieved. Industry claims—and I agree—that the technology is not yet commercially viable, and therefore violates the Clean Air Act’s requirement that CCS be “adequately demonstrated” before it can be imposed as a regulatory requirement. EPA, on the other hand, claims that CCS is feasible.*

*For all the details: I’m currently working on a comprehensive review of the legality of EPA’s Carbon Pollution Standard. It will be done soon and then I will post it here.

However, whether or not CCS technology is achievable may become a moot point, in light of the fact that the technology as envisioned by EPA would increase greenhouse gas emissions, thereby rendering the rule plainly absurd. Allow me to explain.

Due to the high cost of capturing, transporting, and sequestering carbon dioxide, EPA expects that any new coal fired power plants built in the foreseeable future will defray the costs of CCS by selling its carbon dioxide to oil companies, which can use the gas to help extract oil by displacing liquid fuels deep underground, in a process known as CO2 enhanced oil recovery (or CO2-EOR). In the proposed rule, EPA states that, “as a practical matter, we expect that new fossil fuel fired EGUs that install CCS will generally make the captured CO2 available for use in EOR operations (p 262).”

Moreover, EPA expects the CO2 supply created by the Carbon Pollution Standard will spur development of oil recovery. The agency claims,

“oil and gas fields now considered to be ‘depleted’ may resume operation because of increased availability and decreased cost of anthropogenic CO2, and developments in EOR technology, thereby increasing the demand for and accessibility of CO2 utilization for EOR (p 232).”

So…EPA expects that plants complying with the Carbon Pollution Standard will sell their captured CO2 to oil producers. And by increasing the supply of commercial CO2 on the market, EPA posits that the price of CO2 will decrease, leading to a boom in oil and gas production.

But there’s a HUGE problem with EPA’s proposal. It completely fails to take into account the expanded carbon footprint of the oil industry caused by its power plant rule. And, if my admittedly simplistic calculations are correct, EPA’s rule would result in an increase of carbon dioxide emissions.

I should note here that CO2-EOR is an engineering marvel, one that I would never pretend to comprehend. So I called someone who does. And I asked him whether there was a relationship between the amount of CO2 injected in an EOR well, and the amount of oil that comes out. He replied that there was, and that it is known in the industry as the “utilization ratio.” He explained that a utilization ratio is not a static figure. Evidently, the initial stages of drilling require much more CO2 than the later stages. After cautioning that the calculation of a utilization ratio is highly sensitive to assumptions, he said that a reasonably representative utilization ratio is 5,000 cubic feet of CO2 per barrel of oil. I then asked how much does a standard cubed foot of CO2 weigh, and he answered .05189 kilograms. Finally, I looked up online the weight of CO2 emissions from the combustion of a barrel of oil. The answer is 433 kilograms.

With this data, it is possible to calculate a rough approximation of how much CO2 will be created by each kilogram of CO2 captured from a CCS coal plant, and used to enhance oil recovery.

1 Kg CCS CO2*(1 cubed foot CO2/.05189 Kg)*(1 barrel oil/5,000 cubed feet)*(433 Kg CO2/1 barrel oil)

This works out to 1.66 Kg CO2 emitted for each 1 Kg CO2 captured and then used in EOR.

Assuming that a CCS project captures 600 lbs CO2/MWh and that the plant is running at 85% capacity, then a typical coal plant in compliance with EPA’s Carbon Pollution Standard would result in the emission of 1.3 million more kilograms of CO2 than the plant would “save” per megawatt capacity annually. And that doesn’t include the emissions due to the energy input necessary to extract the oil.

Again, I’m no engineer. So if my math is wrong, please let me know (I can be reached at wyeatman@cei.org ). If I’m right, however, then this rule is toast.

The Senate Energy and Natural Resources Committee held a hearing on 17th September on the nomination of Ron Binz to be chairman of the Federal Energy Regulatory Commission.  It was not a pleasant day for Mr. Binz, but his week went downhill from there.

Senator Lisa Murkowski (R-Alaska), ranking Republican on the committee, asked Binz why he had told her in a private meeting that he wasn’t working with an outside PR firm to support his confirmation, when e-mails released soon after showed that he was working with the hard-left firm Venn Squared Communications plus two lobbyists who have many energy company clients.  In response, Binz said, “I apologize if I have left a different impression from what we now agree has happened.”

It didn’t work.  Senator Murkowski announced at the end of the hearing that she could not support Binz’s confirmation.  The next day Senator Joe Manchin (D-WV) announced that he would vote no.  Then Senator Dean Heller (R-Nev.), who always has to worry about what his fellow Nevada Senator, Majority Leader Harry Reid, can do to him, sent out a press release announcing that he would vote no.  By the end of the week, all the Republican Senators on the committee had come out against Binz.  If Manchin plus all the Republicans vote against him in committee mark-up, the nomination will fail on an 11 to 11 tie.

President Obama’s Federal Energy Regulatory Commission (FERC) nominee Ron Binz was caught in a tangle of contradictions during his confirmation hearing Tuesday before the Senate Energy and Natural Resources Committee.

For starters, Ranking Member Lisa Murkowski (R-AK) suggested that Binz misled her during a previous face to face meeting. As reported by Politico’s Darius Dixon,

Murkowski suggested early in the hearing that Binz may have misled her last week when they discussed whom he has worked with to guide his confirmation.

“You’ve effectively got a team — a shadow team* — of lobbyists and PR experts that have been helping throughout,” she told Binz. She added, “But what I can’t reconcile is your statement to me that said the only ones that you were working were the FERC external team.” (full article here)

So that’s one instance of Binz seeming to bend the truth before the U.S. Senate.

Later, during the same hearing, Binz told another apparent whopper. According to our friend Todd Shepherd at Complete Colorado,

Mr. Binz attempted to defend his record on coal by telling Sen. Joe Manchin (D-West Va.), “I approved the largest coal plant that was ever built in Colorado.”* Mr. Binz is referring to the Comanche-3 power plant. Only the Colorado Public Utilities Commission would have the authority to approve new coal plants.

The problem is the fact the decision by Colorado’s PUC to build the largest coal plant in the state’s history came in 2004, according to Xcel Energy’s website. Mr. Binz did not become a member of the PUC board until 2007.

Alas, there’s more.

Regarding a 2010 fuel switching plan that Binz implemented as Chair of the Colorado Public Utilities Commission, the FERC nominee told the junior Senator from West Virginia, “The legislation told us to approve a plan to comply with future EPA regulations.”

Binz clearly was intimating to Sen. Manchin, who represents a pro-coal state, that it was Colorado lawmakers (rather than Ron Binz) who were responsible for the plan that required fuel switching from coal to gas for almost 1,000 megawatts of power generation. But that’s not the whole story. As I explain in this report on Binz’s Colorado history, Binz helped write the fuel switching law! Here’s the relevant excerpt from the report (citations omitted):

Binz’s operating thesis is that “today’s regulation may not be up to the task” of “making over” the utility industry. Thus, Binz sought to expand his regulatory role at the Colorado PUC, in order to facilitate clean energy investment and energy efficiency. To this end, he actually participated in the drafting of legislation that mandated fuel switching from coal to gas for almost 1,000 megawatts of power generation. From a separation of powers perspective, it is unsettling that Binz helped write legislation whose implementation he oversaw. Due to this appearance of impropriety, seven Colorado state senators sent former Colorado governor Bill Ritter a letter demanding that Binz recuse himself from implementing the fuel switching law.

Binz’s seeming difficulty telling the whole truth, and nothing but the truth, was not without consequence. At the hearing, Sen. Murkowski announced her intention to oppose his nomination. And yesterday, Sen. Manchin announced his opposition, citing Binz’s Colorado history.

Assuming that no Republican breaks ranks with Ranking Member Sen. Murkowski and all the Committee Democrats (other than Sen. Manchin) vote for Binz, the Senate Energy and Natural Resources Committee vote is 11 -11. This puts confirmation in doubt. According to National Journal, “since 1987 only five nominations that got a neutral reporting from a committee were brought to the floor, and only one was approved.”

A neutral committee report would be an extraordinary development coming from the Senate Energy and Natural Resources Committee, which is known for harmony. However, Binz is an extraordinary case. As I explain in the aforementioned study on his history in Colorado, Binz has a troubling record of pushing the boundaries of regulatory power in order to discriminate against fossil fuels and promote green energy.

*N.B. The existence of Binz’s “shadow team” was revealed earlier this week by the Washington Times’s Stephen Dinan. His report, in turn, was based on emails obtained by my colleague Chris Horner on behalf the Independence Institute and the Free Market Environmental Law Clinic.
