Even the Benefit of the Doubt Won’t Save EPA’s Mercury Rule

Challenging an agency’s assessment of scientific research in court is typically seen as a fool’s errand. The courts may keep the regulatory state on a close leash where matters of constitutional law are concerned, and will give challenges regarding the proper interpretation of statutes a fair hearing before (usually) deferring to the government’s view. But an agency has to go seriously off the rails before the courts will second-guess its assessment of the scientific record underlying a regulation.

That’s what makes EPA’s super-expensive Mercury and Air Toxics Standards (MATS) rule so interesting: the agency’s own assessment of the scientific research shows there was no good reason to regulate in the first place. The Supreme Court is now reviewing EPA’s decision to plow ahead regardless, irrespective of the costs of doing so.

The Cato Institute’s amicus brief in Michigan v. EPA unpacks EPA’s own scientific assessment to show that regulation certainly is not (as the statute requires) “appropriate and necessary.” 

Power plants emit trace amounts of mercury, and mercury poses a risk to human neurological development when pregnant women consume fish tainted by it. But, as EPA has explained, mercury deposition in the United States “is generally dominated by sources other than U.S. [power plants].” In fact, the agency’s figures show that those plants are responsible for only about one half of one percent of airborne mercury.

Common sense would therefore suggest that reducing or even eliminating emissions from U.S. plants could have little or no appreciable effect on public health. And EPA actually agrees, finding that “even substantial reductions in U.S. [power-plant] deposition…[are] unlikely to substantially affect total risk.”

Repeating News Story: Global Warming To Make Blizzards Worse

Over the next couple of days, as the Nor’easter honing in on the New England coast matures and eventually unleashes its winter storm fury, you are going to be subject to a lot of global warming hype.

After all, the climate change alarmist credo is: let no extreme weather event pass without pointing out that it is “consistent with” climate change caused by human industrial society.

The push has already begun.

But this time around, the pushback is also well-prepared.

While the “curator” of the Washington Post’s newly-minted online “Energy and Environment” section Chris Mooney tells us in his article that global warming may make blizzards worse by increasing the temperature of the western Atlantic ocean and thereby increasing the moisture feed into the developing storm, meteorologist Ryan Maue is quick to point out that just the opposite is likely the result—that the elevated sea surface temperatures actually act to make such storms tamer.

Maue goes on to add that it is “easy to make case that global warming weakened this blizzard significantly due to warmer [sea surface temperatures].”

While Ryan is probably being a bit optimistic here, the reality is that this blizzard (in fact pretty much all storm events) are the result of a very complex system of physical interactions—the precise behavior of each one of which is not completely understood, much less perfectly predictable. This makes ascertaining the influence of human-caused climate change virtually (if not entirely) impossible.

You Ought to Have a Look: Web Reactions to SOTU Climate Claims

You Ought to Have a Look is a feature from the Center for the Study of Science posted by Patrick J. Michaels and Paul C. (“Chip”) Knappenberger. While this section will feature all of the areas of interest that we are emphasizing, the prominence of the climate issue is driving a tremendous amount of web traffic. Here we post a few of the best in recent days, along with our color commentary.

In this week’s installment of You Ought to Have a Look, we take a look at the “climate” section of President Obama’s State of the Union address and highlight some reactions to it from around the web.

A bit of our own reaction is captured in this excellent video of Cato scholars’ responses to the SOTU. As a group, we ranged from being underwhelmed to being horrified.

Here is what the President had to say about the issue of climate change and what he is “doing about it”:

[N]o challenge—no challenge—poses a greater threat to future generations than climate change.

2014 was the planet’s warmest year on record. Now, one year doesn’t make a trend, but this does—14 of the 15 warmest years on record have all fallen in the first 15 years of this century.

I’ve heard some folks try to dodge the evidence by saying they’re not scientists; that we don’t have enough information to act. Well, I’m not a scientist, either. But you know what—I know a lot of really good scientists at NASA, and NOAA, and at our major universities. The best scientists in the world are all telling us that our activities are changing the climate, and if we do not act forcefully, we’ll continue to see rising oceans, longer, hotter heat waves, dangerous droughts and floods, and massive disruptions that can trigger greater migration, conflict, and hunger around the globe. The Pentagon says that climate change poses immediate risks to our national security. We should act like it.

That’s why, over the past six years, we’ve done more than ever before to combat climate change, from the way we produce energy, to the way we use it. That’s why we’ve set aside more public lands and waters than any administration in history. And that’s why I will not let this Congress endanger the health of our children by turning back the clock on our efforts. I am determined to make sure American leadership drives international action. In Beijing, we made an historic announcement—the United States will double the pace at which we cut carbon pollution, and China committed, for the first time, to limiting their emissions. And because the world’s two largest economies came together, other nations are now stepping up, and offering hope that, this year, the world will finally reach an agreement to protect the one planet we’ve got.

Is the Senate Going Lukewarm?

When it comes to opinions about climate change, there have traditionally been two main camps: either you think human activities are warming the climate at a pace that will largely outstrip our ability to adapt and therefore we must take strong and immediate action to try to mitigate it, or, you think climate change is entirely natural and that human activities play virtually no role. But a new, more moderate group is emerging, one colloquially known as the “lukewarmers”—folks who acknowledge a human role in climate change, but who think that the resulting change will be moderate, will remain well within our abilities to adapt, and question the need for actions to mitigate future change in lieu of other, more pressing issues (issues that will go a long way toward improving our adaptive response).

Lukewarmers often find themselves nearly friendless, as neither of the major groups looks favorably on their outlook. “Rational Optimist” Matt Ridley recently took us through his experiences as a lukewarmer—and they weren’t particularly pretty. We’ve had similar experiences ourselves.

But perhaps times are changing.

Yesterday, the U.S. Senate held votes on three different amendments—each climate-related—to be attached to the bill they are currently discussing. That bill aims at wresting the long overdue decision on the Keystone XL pipeline from the State Department, and instead give a congressional green light to the project. (The House as already passed a bill doing the same.) The outcome of the votes seemed to give indication that the Senate was starting to favor the “lukewarming” stance on climate change.

First off, in a vote of 98-1, the Senate found that “climate change is real and it was not a hoax.” Good start!

Then, the Senate pretty much split down the middle, in a 50-49 vote, whether “human activity significantly contributes to climate change,” thus defeating the amendment (which needed 60 votes to pass). The vote was pretty much down party lines, with five Republicans casting a “yea” vote along with all the Democrats. The word “significantly” has so many different meanings that unless you were in the first camp described in our opening paragraph, you would have to vote no, just to be on the safe side (when it comes to protecting yourself from being misconstrued).

U.S. Sugar Maple Tree Distribution Expands with Warmer Temperatures

One of the major concerns with forecast CO2-induced global warming is temperatures might rise so rapidly that many plant species will be driven to extinction, unable to migrate fast enough toward cooler regions of the planet to keep pace with the projected warming. The prospect of species demise and potential extinction have served as a rallying cry in calls for restricting CO2 emissions. But how much confidence should be placed in this climate-extinction hypothesis? Do real world data support these projections? Are plants really as fragile as model projections make them out to be? 

A new paper published in the research journal Botany investigates this topic as it pertains to sugar maple trees, and the findings do not bode well for climate alarmists. In this work, Hart et al. (2014) analyzed “the population dynamics of sugar maple (Acer saccharum Marsh.) trees through the southern portion of their range in eastern North America,” selecting this particular species for this specific task because its range “has been projected to shift significantly northward in accord with changing climatic conditions” by both Prasad et al. (2007) and Matthews et al. (2011).

The three U.S. researchers

analyzed changes in sugar maple basal area, relative frequency, relative density, relative importance values, diameter distributions, and the ratio of sapling biomass to total sugar maple biomass at three spatial positions near the southern boundary of the species’ range using forest inventory data from the USDA Forest Service’s Forest Inventory and Analysis program over a 20-year observation period (1990-2010),” during which time temperatures increased and summer precipitation declined.  

Pope Fallible on Climate Change

Most people think pretty highly of Pope Francis, and I am one of them.  His concern for the poor is exemplary.  His tilt towards gay issues has been widely lauded.  But I am afraid he has been very poorly informed on climate change.

That would be of little consequence, except he is taking the issue very seriously.  Flying to the Philippines on Wednesday, he told reporters  that he will be releasing an encyclical on ecology this coming summer.  According to the AP,

He said he wanted it out in plenty of time to be read and absorbed before the next round of climate change negotiations in Paris in November after the last round in Lima, Peru, failed to reach an agreement.

While he’s definitely right about what happened in Lima, he also is clearly trying to influence the UN process. I guess that’s well and good, after all, the Vatican is a state.  But what is troubling, very troubling, is that poorly informed views on global warming can lead to a tremendously expensive agreement that will do nothing about the climate, while taking away needed resources and exacerbating poverty around the world.

Saturday, in the Philippines, he met with survivors from 2013’s Typhoon Haiyan (also known as Yolanda in the Islands), certainly one of the most powerful storms in recent history. Haiyan reportedly killed 6,000. On the aircraft, Francis said that human activity, meaning emissions of greenhouse gases, was involved. 

A Pope who wants to be as influential as Francis lends great credence to the belief that tropical cyclones (like Haiyan) are being made worse by global warming. These storms are as iconic as polar bears (whose populations are growing) when it comes to generating the political will for a new treaty in Paris. 

It is very easy to see whether global warming is strengthening tropical cyclones.  Dr. Ryan Maue, of Weatherbell Analytics, has examined every storm back to the beginning of global satellite coverage,  for their winds and their duration, which together yield the energy associated with them.  Here’s his result, updated through December 2014:

 

Figure 1. Accumulated Tropical Cyclone Energy, 1972-2014, by Dr. Ryan Maue.  There is simply no relationship between storm activity and global temperature.

The  only way major emissions reductions—of the kind ultimately envisioned by Pope Frances—can be accomplished is to make carbon dioxide-emitting energy so expensive that people will use less, much less.  There’s really no viable energy-dense alternative out there that doesn’t emit CO2. Nuclear fission, which would qualify, is anathema to the same people who want big emissions cuts. His policies will therefore keep the underdeveloped world poor, precisely what he wants to change.

Wealthy societies are much less affected by bad weather than poorer ones. Very strong typhoons regularly strike affluent Hong Kong, with few, if any fatalities.  By making energy unaffordable, the policies Francis wants will impede economic development, so that, decades from now, when a repeat of Haiyan barrels through the Islands, many more will die.

You Ought to Have a Look: Record Global Temperatures

You Ought to Have a Look is a feature from the Center for the Study of Science posted by Patrick J. Michaels and Paul C. (“Chip”) Knappenberger. While this section will feature all of the areas of interest that we are emphasizing, the prominence of the climate issue is driving a tremendous amount of web traffic. Here we post a few of the best in recent days, along with our color commentary.

A lot of buzz around the web was generated late this week with the announcement from the U.S. National Oceanic and Atmospheric Administration that 2014 topped their list as the warmest year since their records began in the late 1800s.

While most of the mainstream media coverage focused on the record-setting temperatures and breathlessly spoke of how this was further indication that humans are warming the climate, the blogosphere was full of articles throwing cold water on this overheated rhetoric by pointing out that despite the past year’s warm temperatures, 1) global warming continues to occur at only a snail’s pace, and 2) this pace is far beneath that projected by the world’s collection of climate models—models developed for the specific purpose of projecting  future climate changes. With each passing year, their performance becomes worse and worse. That is the big story about 2014’s temperatures.

Here are some sites that astutely picked up on that:

Over at Climate Etc., Judy Curry has her say in “‘Warmest year’, ‘pause’, and all that.” Her bottom line?

Berkeley Earth sums it up well with this statement:

That is, of course, an indication that the Earth’s average temperature for the last decade has changed very little.

The key issue remains the growing discrepancy between the climate model projections and the observations: 2014 just made the discrepancy larger.

Speculation about ‘warmest year’ and end of ‘pause’ implies a near term prediction of surface temperatures—that they will be warmer. I’ve made my projection—global surface temperatures will remain mostly flat for at least another decade. However, I’m not willing to place much $$ on that bet, since I suspect that Mother Nature will manage to surprise us. (I will be particularly surprised if the rate of warming in the next decade is at the levels expected by the IPCC.)
