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:

We, the people, still believe that our obligations as Americans are not just to ourselves, but to all posterity.  We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations.  Some may still deny the overwhelming judgment of science, but none can avoid the devastating impact of raging fires, and crippling drought, and more powerful storms.  The path towards sustainable energy sources will be long and sometimes difficult.  But America cannot resist this transition; we must lead it.  We cannot cede to other nations the technology that will power new jobs and new industries – we must claim its promise.  That is how we will maintain our economic vitality and our national treasure – our forests and waterways; our croplands and snowcapped peaks.  That is how we will preserve our planet, commanded to our care by God.  That’s what will lend meaning to the creed our fathers once declared.

Taking these statements one at a time, yes, of course, “We, the people” acknowledge obligations to posterity. Among those obligations is to secure the blessings of liberty. Liberty is endangered when non-elected officials like those at the EPA enact climate policy and erode the separation of powers.

Another obligation to posterity is not to kill the goose that lays the golden eggs. Federal monetary and housing policies destabilized financial markets in 2008, entitlement spending imperils America’s very solvency, carbon taxes or their regulatory equivalent could inflict huge job and GDP losses by making affordable energy costly and scarce, and the green crusade against coal mining, hydraulic fracturing, unconventional oil, and energy exports threatens one of the few bright spots in the economy today. Posterity will not thank us if policymakers foolishly try to tax, spend, and regulate America back to prosperity.

The U.S. contribution to global warming over the 21st century is projected to be small – about 0.2°C, according to the UN IPCC. Even an aggressive de-carbonization program costing hundreds of billions would theoretically avert only about 0.1°C by 2100. Posterity will not thank us for consuming vast resources with so little benefit to public health and welfare.

“Some may still deny the overwhelming judgment of science, but none can avoid the devastating impact of raging fires, and crippling drought, and more powerful storms,” the President says. But even assuming the President is right about the science, since even aggressive emission controls would at best avert only a tiny amount of warming, such policies would afford no protection from fires, drought, or storms.

And what does the President mean by the “overwhelming judgment of science” anyway? Mr. Obama implies that recent fires, drought, and storms would not have occurred but for anthropogenic climate change. That is ideology talking, not science.

That a warmer, drier climate will spawn more frequent forest fires and fires of longer duration is almost a tautology. Nonetheless, some studies find no change in global fire activity over the past century and more. Ocean cycles and forestry practices also influence the frequency and extent of wildfires. Whether recent U.S. wildfires are primarily due to global climate change or other factors is neither obvious nor easily determined.

As for drought, there is no long-term trend in U.S. soil moisture such as might be correlated with the increase in atmospheric GHG concentrations.

Regarding storms, studies find no long-term increase in the strength and frequency of land-falling hurricanes globally over the past 50-70 years and no trend in Atlantic tropical cyclone behavior over the past 370 years.

Hurricane Sandy was a ’super storm’ not because it was an intense hurricane (Sandy was a category 1 before making landfall), but because it was massive in area and merged with a winter frontal storm. The combined storm system contained more integrated kinetic energy (IKE) than Hurricane Katrina. Scientists simply do not know how global climate change affects the formation of such “hybrid” storms.

Inconvenient fact: The USA is currently enjoying the “longest streak ever recorded without an intense [category 3-5] hurricane landfall.”

Explains University of Colorado Prof. Roger Pielke, Jr.: ”When the Atlantic hurricane season starts next June 1, it will have been 2,777 days since the last time an intense (that is a Category 3, 4 or 5) hurricane made landfall along the US coast (Wilma in 2005). Such a prolonged period without an intense hurricane landfall has not been observed since 1900.”

If, as the President seems to assume, all weather anomalies are due to global climate change, then how would he explain the extraordinary 7-year “drought” of intense landfalling U.S. hurricanes?

Mr. Obama says that, “The path towards sustainable energy sources will be long and sometimes difficult.” Indeed. In the famous “Crisis of Confidence“ speech of July 15, 1979, President Jimmy Carter proposed a plan to obtain 20% of America’s energy from solar power by the year 2000. More than three decades later, solar provides 0.25% of U.S. energy (solar contributes 2.5% of all forms of renewable energy combined, which in turn provide 10% of total U.S. energy). Moreover, the piddling contributions of wind, solar power, and biofuels depend on a panoply of government favors: mandates, direct subsidies, and special tax breaks.

The allegedly “sustainable” energy sources championed by the President are not self-sustaining. The main reason is that they are inferior to fossil fuels in terms of energy density (bang for buck) and — in the case of wind and solar power – reliability and dispatchability.

Solyndra, the Obama administration’s mascot solar company that burned through $535 million of the taxpayers’ money before going broke, is not the only failure in the President’s green investment portfolio. The Institute for Energy Research provides information on eight other “stimulosers“ that also “failed, laid off workers, or have a bleak financial outlook.”

Because politicians get to play with other people’s money, hope continually triumphs over experience, and they never learn what three MIT scholars learned from the Carter administration’s energy programs:

If an energy technology is commercially viable, no government support is needed; if it is not commercially viable, no amount of government support can make it so.

The President says that, “America cannot resist this transition; we must lead it. We cannot cede to other nations the technology that will power new jobs and new industries – we must claim its promise.” But that’s just it — how does he know, despite the Solyndra and other failures, the tiny market shares of politically-correct renewables, and the intractable dependence of renewables on policy privileges – that wind and solar power are the future? What information does he have that tens of thousands of savvy investors don’t?

The President alludes to the great clean energy ‘race’ that America supposedly cannot afford to lose. But as my colleague William Yeatman points out, the race is itself a creature of mandate and subsidy. China subsidizes its solar panel manufacturers, for example, because U.S. states establish Soviet-style production quota for renewable energy and EU countries subsidize renewable electricity via feed-in tariffs (FITs). China’s subsidies, in turn, are the official justification for the Stimulus loans to companies like Solyndra. But Beijing is flush with cash; Washington, deep in debt. We cannot outspend China in a subsidy war.

Throwing good money after bad makes even less sense given the global financial crisis and the cutbacks Spain, Germany, France, Greece, Italy, and Ontario (Canada) have been forced to make in their FITs. The renewable market increasingly resembles a bubble (over-investment relative to actual market demand). Yeatman cautions:

When the renewable energy bubble bursts, the global industry leader will be the biggest loser. With that in mind, the supposed race with China for green technological supremacy is one the U.S. would be wise to forfeit.

The climate segment of Mr. Obama’s speech concludes with a theological flourish:

That [investing in clean tech] is how we will preserve our planet, commanded to our care by God.  That’s what will lend meaning to the creed our fathers once declared.

A lot may be implied in those words. Obama refers to the creed — the philosophy of rights and government — articulated in the Declaration of Independence. He seems to suggest that its meaning for our times lies in the doctrine of ‘creation care,’ a green variant of progressive theology. But whereas the Declaration articulated a philosophy of limited government, green theology aims to expand the reach and scope of government. Al Gore gave voice to similar views in his 1992 book on “ecology and the human spirit,” Earth in the Balance. He famously  declared that the time had come to “make rescue of the environment the central organizing principle of civilization.”

Where does Mr. Obama stand on creation care theology and Gore’s central organizing principle? I don’t know but will loudly applaud any journalist who, interviewing the President, has the curiosity and moxie to pursue this line of inquiry.

Last week on National Journal’s Energy Experts Blog, 16 wonks addressed the question: ”Is Washington Ready for a Carbon Tax?” Your humble servant argued that Washington is not ready — unless Republicans are willing to commit political suicide. That’s no reason for complacency, because spendaholics have on occasion gulled the Dumb Party into providing bi-partisan cover for unpopular tax hikes. President G.H.W. Bush’s disastrous repudiation of his ‘read-my-lips, no-new-taxes’ campaign pledge is the best known example.

To help avoid such debacles in the future, I will recap the main points of my National Journal blog commentary. Later this week, I’ll excerpt insightful comments by other contributors.

Nearly all Republicans in Congress have signed the Taxpayer Protection Pledge, a promise not to increase the net tax burden on their constituents. Although a “revenue neutral” carbon tax is theoretically possible, the sudden interest in carbon taxes is due to their obvious potential to feed Washington’s spending addiction. If even one dollar of the revenues from a carbon tax is used for anything except cutting other taxes, the scheme is a net tax increase and a Pledge violation. Wholesale promise-breaking by GOP leaders would outrage party’s activist base. 

Even if the Taxpayer Protection Pledge did not exist, the GOP is currently the anti-tax, pro-energy alternative to a Democratic leadership that is aggressively anti-energy and pro-tax. Endorsing a massive new energy tax would damage the product differentiation that gives people a reason to vote Republican. Recognizing these realities, House GOP leaders recently signed a ‘no climate tax’ pledge.

That’s good news. But this is a season of fiscal panic and I was there (in 1990) when the strength of Republicans failed. Perhaps the best time to kick carbon taxes is when they are down. So let’s review additional reasons to oppose a carbon tax.

Carbon taxes are regressive, imposing a larger percentage burden on low-income households. If Republicans support a carbon tax in return for cuts in corporate or capital gains taxes (a popular idea in some circles), they will be pilloried — this time fairly — for seeking to benefit the rich at the expense of the poor.

If, on the other hand, the tax provides “carbon dividends” to offset the impact of higher energy prices on poor households, it will create a new class of welfare dependents. Guess which party is better at organizing people on welfare?

Carbon taxes pose an existential threat to the development of North America’s vast coal, oil, and natural gas deposits — one of the few bright spots in the economy. The core purpose of a carbon tax is to reduce and, ultimately, eliminate carbon doxide-emitting activities. The tax ‘works’ by shrinking the economic base on which it is levied. To keep revenues up, carbon tax rates must continually increase as emissions decline. Likely result: an exodus of carbon-related capital, jobs, and emissions (“carbon leakage”). Problem: Nobody knows how to run a modern economy on cellulose, wind turbines, and solar panels. Bipartisanship on carbon taxes means co-ownership of U.S. economic decline.

In umpteen hearings on the Solyndra debacle, Republicans excoriated the Obama administration for trying to pick energy market winners and losers. A carbon tax is an even more ambitious green industrial policy than the $34.5 billion in loan guarantees  lavished by the Department of Energy (DOE) on a few dozen renewable energy projects. Carbon taxes attempt to pick and losers across the entire economy, handicapping all firms that produce or rely on carbon-based energy. Indeed, central to Solyndra’s business plan and DOE Secy. Chu’s green tech strategy was the bet that Congress would enact cap-and-trade, the regulatory surrogate for a carbon tax.

Some economists say government should tax ‘bads’ like emissions rather than ‘goods’ like labor and capital. This is sloppy thinking. In technical economic terms, only finished products and services are ‘goods.’ Labor and capital are inputs, production factors, or costs. Energy too is a key input. Without energy, most labor and capital would be idle or not even exist. About 83% of U.S. energy comes from carbon-based fuels. So a carbon tax also taxes what these economists loosely call ‘goods.’ Pretending that carbon taxes only tax emissions and nothing of value is free-lunch economics — a recipe for failure and worse.

Some speculate about a grand bargain in which carbon taxes replace carbon regulations — everything from the EPA’s greenhouse gas emission standards to California’s cap-and-trade program to State-level renewable electricity mandates. The EPA, the California Air Resources Board, the major environmental organizations, and the renewable energy lobbies have spent decades building the regulatory programs they administer or influence. They want to add carbon taxes to carbon regulation, not substitute one for the other. Talk a grand bargain is a ploy designed to lure gullible Republicans to the negotiating table. Few if any of the Left’s regulatory sacred cows would be traded away. In the meantime, carbon tax negotiations would divide GOP leaders from their rank and file and demoralize the party’s activist base.

The backlash against GOP leaders’ complicity would be swift and severe. Yet for all the economic pain inflicted and political damage incurred, they would accomplish no discernible environmental gain. As hurricane expert Roger Pielke Jr. points out, even under IPCC assumptions, changes in energy policy “wouldn’t have a discernible impact on future disasters for the better part of a century or more.” Similarly, also using IPCC assumptions, Chip Knappenberger of the Cato Institute Center for the Study of Science calculates that even if the U.S. eliminated all CO2 emissions tomorrow, the impact on global temperatures would be a reduction ”of approximately 0.08°C by the year 2050 and 0.17°C by the year 2100 — amounts that are, for all intents and purposes, negligible.”

Under a carbon tax, the U.S. would keep emitting billions of tons of carbon dioxide annually for a long time – otherwise the tax wouldn’t raise much revenue. So the notion that carbon taxes can measurably reduce extreme weather risk or climate change impacts within any policy-relevant timeframe is ludicrous.

How long will scientists have to measure annual economic damages from hurricanes before they can confidently say that global warming is making storms stronger? In An Inconvenient Truth, Al Gore claimed the evidence is already clear in the damage trends of the last several decades. But a new study finds that any warming-related increase in hurricane damages won’t be detectable for a century a more.

Last week I blogged about a study (Bouwer, L.M. 2011) debunking a misconception — popularized in Al Gore’s film, An Inconvenient Truth — that we know global warming intensifies extreme weather events because economic damages from extreme weather keep going up, decade after decade.

Gore did not realize that the economic loss data he was looking at had not been adjusted (“normalized”) to take into account changes in socio-economic factors — notably population, wealth, and the consumer price index — that massively affect how much damage a particular weather event inflicts.

As discussed in last week’s post, Laurens M. Bouwer of the Institute for Environmental Research in the Netherlands analyzed 22 previous studies attempting to find an anthropogenic warming “signal” in normalized weather-related loss data. Bouwer’s key conclusion:

The studies show no trends in losses, corrected for changes (increases) in population and capital at risk, that could be attributed to anthropogenic climate change. Therefore, it can be concluded that anthropogenic climate change so far has not had a significant impact on losses from natural disasters.

But what about the future? Most IPCC climate models project an increase in the strength of tropical storms and hurricanes as the oceans warm. When will the climate-change contribution to hurricane-related economic losses (assuming there is one) be detectable in normalized loss data?

That is the question Ryan Crompton, Roger Pielke, Jr., and K. John McAneney explore in a recent study. The short answer is that nobody reading this post today will likely be around when (if) the warming signal emerges!

The researchers set out to determine “the time it would take for anthropogenic signals to emerge in a time series of normalized US tropical cyclone losses.” That is, they seek to determine the anthropogenic signal’s “emergence timescale.” By “cyclone,” the authors include all Atlantic tropical storms (up through category 5 hurricanes) with maximum sustained wind speeds of at least 63 kph.

To project changes in hurricane behavior over time, the authors used the IPCC’s 18-model ensemble plus other projections from four of the ensemble’s leading models (Geophysical Fluid Dynamics Laboratory, Japanese Meteorological Research Institute, Max Planck Institute, and Hadley Centre UK Meteorological Office).

Here’s what they found:

The emergence timescale of these anthropogenic climate change signals in normalized losses was found to be between 120 and 550 years. The 18-model-based ensemble signal emerges in 260 years.

The researches thus ”urge extreme caution in attributing short-term trends (i.e. over many decades and longer) in US tropical cyclone losses to anthropogenic climate change,” stating that “anthropogenic climate change signals are unlikely to emerge in US tropical cyclone losses on timescales of less than a century under the projections examined here.”

Note, the study does not mean scientists will not know for 120-550 years whether global warming intensifies hurricanes. As the authors write: “Our result confirms the general agreement that it is far more efficient to seek to detect anthropogenic signals in geophysical data rather than in loss data.” Nonetheless, if the study means what I think it does, it will be a long time before any “short-term” (multi-decadal) trend in hurricane losses can be attributed to global warming rather than to socio-economic factors and/or natural variability.

What is the policy implication? ”Our results argue strongly against using abnormally large losses from individual Atlantic hurricanes or seasons as either evidence of anthropogenic climate change or to justify actions on greenhouse gas emissions. There are far better justifications for action on greenhouse gases.” The authors don’t specify those “better justifications,” which presumably are outside the scope of their paper.

Although not mentioned by the authors, the study should pour cold water on some CO2 tort cases. In Comer v. Murphy Oil, for example, plaintiffs sued a wide range of energy, fossil fuel, and chemical companies for economic damages from Hurricane Katrina, alleging that the companies’ emissions contributed to global warming, which in turn increased the power of the storm.

Armed with the timescale emergence study, defendents in such a case could argue that their contribution to a hurricane’s power is not only undetectable today but will likely remain so for a century or more.
