Sixty-Five Scientists Demand Reconsideration Of EPA’s Endangerment Finding

Francis Menton

Today a large group of some sixty-five top scientists sent a letter to EPA Administrator Scott Pruitt demanding that he initiate a process to reconsider the so-called Endangerment Finding of 2009.

See the Letter and the 64 signatories. We know that many more scientists would have been pleased to sign this letter if they had only known about it. Scientists may ask to have their name added by simply sending their info to THSResearch@aol.com.

Regular readers of this blog will recognize the EF as one of the most egregious and preposterous bureaucratic power grabs of all time.  By the EF, EPA purported to “determine” that carbon dioxide—a colorless, odorless gas that has no known adverse health effects at any concentration you will ever experience and that is the basis for all life on earth—is a “danger” to human health and welfare.  The so-called science underlying the EF is and always was a joke.  See, for example my post “The ‘Science’ Underlying Climate Alarmism Turns Up Missing” from September 2016 (and multiple similar posts).  Nevertheless, the EF was used by the Obama administration as the basis for, among other things, its Clean Power Plan, seeking to force the closure of all coal-fired power plants (and ultimately the closure of all power plants involving any fossil fuel).  Just today, a group of about seventeen “blue” states and their environmentalist co-parties filed a brief in the D.C. Circuit (behind pay wall) seeking to compel the Trump administration to reinstate the CPP or something like it, on the grounds that the EF requires the government to regulate emissions of carbon dioxide. 

Here is a link to today’s letter.  And here is the full text:

You have pending before you two science-based petitions for reconsideration of the 2009 Endangerment Finding for Greenhouse Gases, one filed by the Concerned Household Electricity Consumers Council, and one filed jointly by the Competitive Enterprise Institute and the Science and Environmental Policy Project.

We the undersigned are individuals who have technical skills and knowledge relevant to climate science and the GHG Endangerment Finding. We each are convinced that the 2009 GHG Endangerment Finding is fundamentally flawed and that an honest, unbiased reconsideration is in order.

If such a reconsideration is granted, each of us will assist in a new Endangerment Finding assessment that is carried out in a fashion that is legally consistent with the relevant statute and case law.

We see this as a very urgent matter and therefore, request that you send your response to one of the signers who is also associated with a petitioner, SEPP.

Readers here will also recognize that I am serving as a lawyer for one of the Petitioners (the Concerned Household Electricity Consumers Council) seeking reconsideration of the EF.  Our group issued a press release this morning simultaneous with the release of the scientists’ letter to Administrator Pruitt.  Key points from our press release:

The Concerned Household Electricity Consumers Council fully endorses the recommendations of these scientists because recent research has definitively validated that: once certain natural factor (i.e., solar, volcanic and oceanic/ENSO activity) impacts on temperature data are accounted for, there is no “natural factor adjusted” warming remaining to be attributed to rising atmospheric CO2 levels. That is, these natural factor impacts fully explain the trends in all relevant temperature data sets over the last 50 or more years. At this point, there is no statistically valid proof that past increases in atmospheric CO2 concentrations have caused what have been officially reported as rising, or even record setting, global average surface temperatures (GAST)… Moreover, additional research findings demonstrate that adjustments by government agencies to the GAST record render that record totally inconsistent with published credible temperature data sets and useless for any policy purpose…

This scientifically illiterate regulation [based on the EF] will raise U.S. energy prices thereby reducing economic growth and jobs as well as our National Security… The Electricity Consumers Council therefore, based on this new scientific evidence, must insist that the EPA grant the “very urgent” request of these scientists “that an honest, unbiased reconsideration is in order.”

I won’t attempt to list here who all the letter’s signers are, but if you go to the link you will see that they are a who’s who of the top scientific people active on these issues.  To the extent that credentials count for anything in today’s corrupted world, many of them have top degrees and top professorships at top institutions. 

Now, perhaps you have seen the claim that “97% of scientists agree” that human-caused global warming is a crisis, or something like that.  I guess that would have to mean that the alarmist team will shortly produce a responsive letter signed by in excess of 2000 comparably-qualified scientists.  Don’t bank on it.  No such group exists.  Yes, there is a substantial government-funded clique of lightweights and charlatans that spend their lives manipulating the world temperature records and putting out fake press releases of “hottest year ever!” Undoubtedly they can exceed our group in numbers (government dollars buy a lot of loyalty and corruption).  But no such group that could be assembled could remotely match our group of sixty-five for bona fide scientific heft.  If they try to assemble such a group, the contrast of the real scientists versus the lightweights will be immediately apparent. 

And by the way, the signing process for our scientists’ letter is still open, and we expect the number of signers to increase over time.  Let the games begin!

What made this hurricane season so active in the Atlantic?

Joseph D’Aleo

What a hurricane season! It started very early with Arlene in April but the real action held off until the last week of August when Hurricane Harvey flooded Texas and Louisiana.. Harvey was the first hurricane to make landfall in Texas since Ike in 2008 and Category 4 hurricane in Texas since Hurricane Carla in 1961.

Irma, the 11th strongest Atlantic storm on record (using central pressure, the most reliable measure) had major impacts on Islands like Barbuda and St. Martin, the Virgin Islands, the Turks and Caicos and southern Bahamas. Then crossing northern Cuba it curled back into Florida. It was the first landfalling hurricane and major hurricane in Florida since Wilma in 2005.


Jose too became a major hurricane, but never made landfall though it created large swells along the eastern seaboard and pounded southeastern New England, Cape Cod and the islands with tropical storm winds and coastal flooding as it stalled for days.

Maria was the third major Hurricane, the 10th strongest Atlantic storm, crossed the northern Leeward Islands and plowed through Puerto Rico, doing catastrophic damage to the island.  It then moved north into the Atlantic, close enough to pound the Atlantic coast with large swells from Florida to New Jersey.

And then Hurricane Nate avoided another ‘Katrina moment’ for New Orleans but produced storm surge damage to southeast Louisiana, Mississippi, Alabama and the Florida Panhandle.

Before the landfall of two major storms on the U.S. we had gone just short of 12 years without a major hurricane landfall, the longest such lull since the 1860s.

The quiet period came after three big years. Isabel made landfall on the Mid Atlantic in 2003, Charley, Frances, Ivan and Jeanne in 2004 and Dennis, Katrina, Rita and Wilma in 2005 all made landfall on the mainland.  Emily in 2005 was another major hurricane but turned west into Mexico. 2005 holds the record for 5 category 4 or greater and 4 category 5 impact storms. Some speculated this was the new norm for the Atlantic before nature gave us that 12-year break.

So what causes long quiet spells and then big years like 2004 and 2005 and now 2017?

Nothing is new in weather. Great Colonial hurricanes in the northeast with storm surges up to 20 feet occurred in 1635 and 1675. A Katrina like storm made landfall in Louisiana in 1722 with major flooding and damage in Louisiana.  The Great Chesapeake storm in 1769 like Isabel in 2003 brought major flooding to North Carolina and Virginia.  In the Caribbean, the Great Hurricane of 1780 killed an estimated 27,500 people while ravaging the islands of the eastern Caribbean with winds estimated to top 200 mph. It was one of three hurricanes that year with death tolls greater than 1000. 

1893, had at least 10 hurricanes. Of those, 5 became major hurricanes. Two of the hurricanes caused over two thousand (2000) deaths in the United States; at the time, the season was the deadliest in U.S. history.

1886 came close with at least 10 hurricanes, 7 making landfall.  4 of the hurricanes were major hurricanes.


The Galveston Hurricane in1900 killed at least 8,000 people with some estimates as high as 12,000, making it the deadliest natural disaster in U.S. history.

Ok, major hurricanes have occurred even during cold periods but is there a trend in the modern record?


The Accumulated Cyclone Energy Index which takes into account the number, duration and strength of all tropical storms in a season. The ACE index is a wind energy index, defined as the sum of the squares of the maximum sustained surface wind speed (knots) measured every six hours for all named storms while they are at least tropical storm strength.

The Accumulated Cyclone Energy Index for the Atlantic shows a cyclical behavior with no long term trend but with spikes in 1893, 1926, 1933,1950 then again in 1995, 2004 and 2005. 2017 ranks 8th now with still weeks to go this season.



So what causes long breaks and then big years like 2004 and 2005 and now 2017?


The North Atlantic like the Pacific undergoes multi-decadal changes in ocean temperature and pressure patterns. It has long been known, when the Atlantic is in what is called its’ warm mode, there are more storms.  Since 1995, when the current warm Atlantic mode began, we have average 14.6 named storms per year, more than 5 more than the long-term 1851-2017 average.


An important factor that affects whether hurricanes affect the United States is El Nino and La Nina. When El Ninos develop, more storms develop in the eastern and central Pacific threatening Mexico, Hawaii and sometimes in weakened forms Arizona and California.

These storms enhance high-level winds that cross into the Atlantic. These winds produce shear that disrupts developing storms causing them to weaken or dissipate and/or turn harmlessly north into the North Atlantic. Storms can still develop near the coast where the water is warm like in the Gulf and near the Gulf Stream off the southeast coast.

When La Ninas develop there are usually fewer storms in the eastern Pacific and less shear to disrupt the Atlantic storms.

In warm Atlantic years, that means trouble as the storms can track the entire Basin with more time to turn into major hurricanes. Even the east coast is more vulnerable to a landfalling hurricane. We had 8 high impact east coast hurricanes from 1938 to 1960 and 9 from 1988 to 2012.

The last important La Nina stretch was in 2010/11 to 2011/12. We avoided a major hurricane hit, though major hurricanes at sea made final landfall in the NYC metro - Irene (as a tropical storm) in 2011 and Sandy in 2012 (as a post tropical cyclone).

They caused massive flooding (from rains with Irene in upstate NY and Vermont and from a storm surge with Sandy in New York City and New Jersey).


We are still in the latest Atlantic warm period. This year, a spring attempt at an El Nino failed a La Nina like conditions developed. Had El Nino succeeded we may have had Harvey, which developed near the Texas coast and Nate which came out of the bath water in the western Caribbean but maybe Irma and Maria would have been weakened or deflected.  But with La Nina conditions developing, no shear and warm Atlantic water we saw a return to big storms just as we saw in 2004 and 2005. 


It may not be over as in 2005, we had Wilma come out of the Caribbean in late October.

At Weatherbell, Joe Bastardi led the team in the tropical outlook and correctly called for a big season. When the water in the Main Development Regions warmed further, Joe upped the ACE forecast and the team began alerting that come mid-August, big things would happen.


So when we get a year like 2017 or back-to-back bad years like 2004 and 2005, we have to accept that is how the weather works. Permadroughts ended with record wet years for Texas and California this decade. The record nearly 12 year major hurricane ‘drought’ ended with 2017. 

BTW, when the Atlantic is active, the Pacific usually is less so. See how the western Pacific and Indian Ocean activity averaged 50% of normal and the eastern Pacific 20% below normal while the Atlantic activity (ACE Index as 236% of normal.

Corrupt Climate Science Discredits NASA

By Larry Bell

Lots of global warming alarmists are hyperventilating over President Donald Trump’s pick of U.S. Rep. Jim Bridenstine, R-Okla. a “climate change denier,” to head NASA.

Hopefully, he will give them good reason for cold sweats by ending the agency’s politically corrupt and embarrassing role in perpetuating history’s arguably most costly fraud.

Harsh words? You bet!

Lest there be any confusion, I am referring here to a tiny politically-protected group of climate model theorists called the Goddard Institute for Space Studies (GISS) operating above a restaurant in a midtown Manhattan office building nowhere near a major NASA facility. Ironically, GISS has virtually nothing to do with studying space, much less honoring its legendary namesake, Dr. Robert H. Godard, who is widely recognized as the father of American rocketry.

Instead, NASA GISS is far more publicly associated with its long-time head Dr. James Hansen, who is appropriately recognized as the godfather of a global warming alarm syndicate. Hansen even retained his position following four handcuffed arrests for noncompliance with police orders during eco-activist anti-fossil energy demonstrations.

GISS is well-known for headline-grabbing media claims that “NASA warns hottest day, month or year.” They have a long history of “tuning” global temperature data and abbreviating recorded timelines to make the past colder in order to have recent temperatures appear remarkably warmer.

Dr. Reto Ruedy of GISS once confessed in a Climategate e-mail that GISS had inflated its temperature data since 2000 on a questionable basis, whereby, “NASA’s assumption that the adjustments made the older data consistent with future data ... may not have been correct.”

Nevertheless, we’re supposed to accept that this information is still good enough for government work. As Reudy explained in a memo to USA Today’s weather editor, “We are basically a modeling group… for that purpose what we do is more than accurate enough [to assess model results].”

My highly concerned friend Apollo 7 astronaut Walter Cunningham doesn’t accept this as good enough for NASA. He wrote, “Those of us fortunate enough to have traveled in space bet our lives on the competence, dedication, and integrity of the science and technology professionals who made our missions possible… In the last twenty years I watched the high standards of science being violated by a few influential climate scientists, including some at NASA, while special interest opportunists have dangerously abused our public trust.”

GISS’s shoddy performance shouldn’t be good enough for Jim Bridenstine either. Whereas he doesn’t question the reality that climate changes, he has very good reasons to challenge lousy pretend science… particularly when it is purported to represent the best research and thinking of an agency which has accomplished legendary scientific and technological progress.

Speaking on the U.S. House floor in 2013, Bridenstine said, “Mr. Speaker, global temperatures stopped rising 10 years ago. Global temperature changes, when they exist, correlate with sun output and ocean cycles. During the Medieval Warm Period from 800 to 1300 A.D. - long before cars, power plants, or the Industrial Revolution - temperatures were warmer than today. During the Little Ice Age from 1300 to 1900 A.D., temperatures were cooler. Neither of these periods were caused by any human activity.”

Incidentally, Bridenstine also believes in a need for good weather research. He even co-authored H.R. 353, the Lucas-Bridenstine Weather Research and Forecasting Act which was recently signed into law.

Sen. Sherrod Brown, D-Ohio, has argued that Bridenstine’s “ . . .doubt that humans contribute to climate change - a research area in which NASA is intimately involved” and lack of “experience in scientific research or academia” should disqualify him from heading the agency.

Yet if having academic credentials in climate science is important, one might imagine that it would be doubly so for anyone heading NASA’s climate research activities. Gavin Schmidt, Ph.D, a mathematician who now heads NASA GISS holds no climate or Earth science degrees either.

Duane Thresher, a former GISS employee for seven years, posted a letter to the prospective new NASA administrator in his Sept. 8 Real Climatologists blog titled, “Bridenstine, Climate Scientists Are Not Noble, Stop Paying Them.”

Thresher, who is highly critical of the abysmal lack of GISS science competence and integrity, wrote that when bureaucrats decided that global warming was the next big thing, there was a huge influx of money and unqualified people who spent it including opportunists, carpetbaggers… the corrupt and ignoble.

It is tragic to see the agency that applied solid science to put humans the Moon become publicly identified with and misrepresented by a junk science-premised climate alarm propaganda machine. While no one I know denies that natural climate changes, it’s high time for a political climate change that gets NASA back to doing reliable science we can once again trust.

Duane Thresher’s advice should be heeded, “NASA GISS is a monument to bad science that truly should be torn down. Take the money and buy a rocket.”

See Tony Heller attack on the Obama era NCA hoax study which Katherine Hayhoe of Texas Tech who promised permadrought in Texas just before the wettest year on record and then Harvey. No surprise she is a cherry picker cheer leader, as she was a student of the equally climate illiterate or at least misinformer Donald Wuebbles, who with Katherine were co-lead authors of the shelved corrupt CSSR report.

Despite Harvey and Irma, science has no idea if climate change is causing more (or fewer) storms

By Ross McKitrick

Update: WeatherBELL video on why this season was so active


After Hurricane Harvey hit Texas, it didn;t take long for climate alarmists to claim they knew all along it would happen. Politico’s Eric Holthaus declared “We knew this would happen, decades ago.” Naomi Klein stated “these events have long been predicted by climate scientists.” Joe Romm at ThinkProgress wrote, “the fact is that Harvey is exactly the kind of off-the-charts hurricane we can expect to see more often because of climate change.”

According to these and other authors, rising greenhouse gas levels are at least partly to blame for the occurrence and severity of Harvey, and probably for Hurricane Irma as well. But after-the-fact guesswork is not science. If any would-be expert really knew long ago that Harvey was on its way, let him or her prove it by predicting what next year’s hurricane season will bring.

Don’t hold your breath: Even the best meteorologists in the world weren’t able to predict the development and track of Hurricane Harvey until a few days before it hit.

This is why the idea of climate science being “settled” is so ludicrous, at least as regards the connection between global warming and tropical cyclones. A settled theory makes specific predictions that can, in principle, be tested against observed data. A theory that only yields vague, untestable predictions is, at best, a work in progress.

The climate alarmists offer a vague prediction: Hurricanes may or may not happen in any particular year, but when they do, they will be more intense than they would have been if GHG levels were lower. This is a convenient prediction to make because we can never test it. It requires observing the behaviour of imaginary storms in an unobservable world. Good luck collecting the data.

Climate scientists instead use computer models to simulate the alternative world. But the models project hundreds of possible worlds, and predict every conceivable outcome, so whatever happens it is consistent with at least one model run. After Hurricane Katrina hit New Orleans in 2005, some climate modelers predicted such storms would be more frequent in a warmer world, while others predicted the opposite, and still others said there was no connection between warming and hurricanes.

What ensued was an historically unprecedented 12-year absence of major (category 3 or higher) hurricanes making landfall in the United States, until Harvey, which ties for 14th-most intense hurricane since 1851. The events after 2005 were “consistent with” some projections, but any other events would have been as well.

The long absence of landfalling hurricanes also points to another problem when opinion writers connect GHGs to extreme weather. Science needs to be concerned not only with conspicuous things that happened, but with things that conspicuously didn’t happen. Like the famous dog in the Sherlock Holmes story, the bark that doesn’t happen can be the most important of all.

It is natural to consider a hurricane a disruptive event that demands an explanation. It is much more difficult to imagine nice weather as a disruption to bad weather that somehow never happened.

Suppose a hurricane would have hit Florida in August 2009, but GHG emissions prevented it and the weather was mild instead. The “event,” pleasant weather, came and went unnoticed and nobody felt the need to explain why it happened. It is a mistake to think that only bad events call for an explanation, and only to raise the warming conjecture when bad weather happens. If we are going to tie weather events to GHGs, we have to be consistent about it. We should not assume that any time we have pleasant weather, we were going to have it anyway, but a storm is unusual and proves GHG’s control the climate.

I am grateful to the scientists who work at understanding hurricane and typhoon events, and whose ability to forecast them days in advance has saved countless lives. But when opinion writers tacitly assume all good weather is natural and GHGs only cause bad weather, or claim to be able to predict future storms, but only after they have already occurred, I reserve the right to call their science unsettled.

Texas Major Hurricane Intensity Not Related to Gulf Water Temperatures

Dr. Roy Spencer

August 29th, 2017

As the Houston flood disaster was unfolding, there is considerable debate about whether Hurricane Harvey was influenced by “global warming”. While such an issue matters little to the people of Houston, it does matter for our future infrastructure planning and energy policy.

Let’s review the two basic reasons why the Houston area is experiencing what now looks like a new record amount of total rainfall, at least for a 2-3 day period over an area of tens of thousands of square miles.

1) A strong tropical cyclone, with access to abundant moisture evaporated off the Gulf of Mexico, and

2) Little movement by the cyclone.

These two factors have conspired to create the current flooding catastrophe in Houston. Now let’s look at them in the context of global warming theory.

1. Are Texas major hurricanes dependent on an unusually warm Gulf?

I examined all of the major hurricane (Cat 3+) strikes in Texas since 1870 and plotted them as red dots on the time series of sea surface temperature variations over the western Gulf of Mexico. As can be seen, major hurricanes don’t really care whether the Gulf is above average or below average in temperature:


Red dots indicate years of major hurricane strikes in Texas, plotted on average SST departures from normal by year over the western Gulf of Mexico (25-30N, 90-100W).

Why is that? It’s because hurricanes require a unique set of circumstances to occur, and sufficiently warm SSTs is only one. (I did my Ph.D. dissertation on the structure and energetics of incipient tropical cyclones, and have published a method for monitoring their strength from satellites).

The Gulf of Mexico is warm enough every summer to produce a major hurricane. But you also usually need a pre-existing cyclonic circulation or wave, which almost always can be traced back to the coast of Africa. Also, the reasons why some systems intensify and others don’t are not well understood. This is why the National Hurricane Center admits their predictions of intensity change are not that accurate. Lots of thunderstorm complexes form over warm tropical waters, and we still don’t understand why some of them will spontaneously form a cyclonic circulation.

2. Does global warming cause landfalling hurricanes to stall?

I don’t know of any portion of global warming theory that would explain why Harvey stalled over southeast Texas. Michael Mann’s claim in The Guardian that it’s due to the jet stream being pushed farther north from global warming makes me think he doesn’t actually follow weather like those of us who have actual schooling in meteorology (my degree is a Ph.D. in Meteorology). We didn’t have a warm August in the U.S. pushing the jet stream farther north.

In fact, I dare anyone to look at the August temperature anomalies to date in the U.S. (courtesy of Weatherbell.com) and tell me, exactly what pattern here is due to global warming?

Enlarged August 2017 (through Aug. 28) surface temperature anomalies around North America (NCEP CFSv2, courtesy of Weatherbell.com).

The flooding disaster in Houston is the chance occurrence of several factors which can be explained naturally, without having to invoke human-caused climate change. We already know that major landfalling hurricanes in the U.S. have been less frequent in recent decades. But once one forms, if it stalls near the coast (a rarity), it can be expected to cause a flooding disaster… especially in a flood-prone area like Houston.
