The Greatest Scientific Fraud Of All Time—Part XIX

By Francis Menton

Don’t be too surprised that you’re not reading much recently about the impending climate apocalypse and the supposed “hottest year,” “hottest month,” or “hottest day” ever.  The reason is that global lower troposphere temperatures, as measured by satellites and published by UAH, are down by more than 0.7 deg C since early 2016.  That’s well more than half of what was thought to be the temperature increase since the satellite record began in 1979.  September 2018 turned out to be the coolest September in ten years.

But inquiring minds are still eager to get to the bottom of the temperature adjustment scandal that has created a fake warming trend in the so-called “surface temperature” record that goes back into the mid-1800s.  For those unfamiliar with this field, the “surface temperature” record comes from a totally different source from the satellite record, namely a network of conventional thermometers, each located a few feet above the ground, scattered around the world.  The data from the surface thermometers is collected and published by three entities, two in the U.S. (NASA and NOAA) and one in England (the Hadley Center at the Climatic Research Unit of the University of East Anglia).  Those three use somewhat different but substantially overlapping surface thermometers to compile their records.  All three show a noticeable warming trend in the range of 1.5 deg C since the late 19th century.

But is the warming trend real, or is all or most of it an artifact of temperature adjustments made to the record over time?  Many have noticed that substantial downward adjustments have been made to raw temperatures recorded at many of the stations in the surface thermometer networks during the earlier part of the record, mainly from the mid-1800s through 1950s.  This issue has been the principal focus of my series The Greatest Scientific Fraud Of All Time.  This is now Part XIX of that series.

Here’s the new development:  A guy named John McLean has just (October 2018) published a big Report via John Boyle Publishing, essentially consisting of an expanded and updated version of his 2017 Ph.D. thesis for James Cook University in Australia.  For his thesis, McLean elected to conduct an “audit” of one of the surface temperature records, that of the Hadley Center at UEA, a series known as HadCRUT4.  The HadCRUT4 series is the main series relied on by the IPCC for its warnings of climate alarm propounded to the governments of the world.  The full McLean Report is behind a pay wall, where it can be purchased for $8.  I have purchased a copy.  The Executive Summary and some other excerpts can be found at Watts Up With That here

McLean’s audit is scathing in many respects.  He covers everything from impossibly crazy temperature readings that nobody bothers to examine or correct (one town in Colombia records a three-month period with an average temperature over 80 deg C, which is 176 deg F) to ridiculous sparsity of data (in some of the early years, the entire southern hemisphere has only one land-based weather station), and so on.  The overall conclusion:

Governments and the United Nations Framework Convention on Climate Change (UNFCCC) rely heavily on the IPCC reports so ultimately the temperature data needs to be accurate and reliable.  This audit shows that it is neither of those things.

By all means buy the Report and read it if you have the time.  In this post I’m going to focus mainly on one portion of it, which is the part that addresses the issue of the early-year downward temperature adjustments.

For extensive background on this temperature-adjustment issue, you can read the previous posts in this series.  To make it a little easier to grasp, I’ll throw in this graph from Part XVIII of the series, posted in January of this year.  This graph shows current and earlier versions of temperature data from the station at Geneva in upstate New York.  Note that this data is from GISS (NASA) rather than HadCRUT, but the adjustment issues are comparable:


Somehow temperatures prior to 1950 have been adjusted downward by in excess of 2 deg C; and between 1950 and 1970 by in excess of 1 deg C.  That’s one way to create a strong warming trend!  But how has that been done, and how do we know that the adjustments are appropriate?  None of NASA, NOAA or Hadley/CRU have been forthcoming with anything approaching an adequate explanation.

Now McLean weighs in with some insights.  From the Executive Summary:

Another important finding of this audit is that many temperatures have been incorrectly adjusted. The adjustment of data aims to create a temperature record that would have resulted if the current observation stations and equipment had always measured the local temperature. Adjustments are typically made when station is relocated or its instruments or their housing replaced.

The typical method of adjusting data is to alter all previous values by the same amount. Applying this to situations that changed gradually (such as a growing city increasingly distorting the true temperature) is very wrong and it leaves the earlier data adjusted by more than it should have been. Observation stations might be relocated multiple times and with all previous data adjusted each time the very earliest data might be far below its correct value and the complete data record show an exaggerated warming trend.

There is much more on this subject in the body of the Report, particularly pages 82 to 86.  McLean asserts that something like the following is a frequent occurrence:  A measuring site, originally located in an undisturbed rural area, gradually becomes surrounded by urban build-up, and becomes subject to the urban heat island effect.  Thus, the temperatures it is recording are “too high” at least as compared to some theoretical un-affected “true” temperature.  At some point, the station is appropriately moved to a new location without the urbanization.  The difference between the temperatures recorded at the new and old locations is calculated.  And then - and here is the key error - the temperatures at the old location are adjusted downward by the amount of that difference, for all times going back to the beginning of the station.  But here’s the error: in its early years, the station was not affected by an urban heat island, so temperatures from that period should not be adjusted downward.  Yet they are.  From page 84 of the Report:

It is incorrect but seemingly common to apply a constant adjustment to all data from the first site according the calculated difference between it and the second site when the data at the first site has been distorted by gradual changes in the local environment. It defies logic that a location that was abandoned because it was contaminated by external influences was equally contaminated when the observation station was first established there and throughout the entire time that the station was at that site, but this is what a constant data adjustment implies. 

So, can an independent researcher at least be given the adjustment methodology so that the process can be reverse-engineered and corrected?  From page 82:

Much of the observation station data used in HadCRUT4 is likely to have been adjusted but there is no record of the method used or the amount of the adjustment, which makes the data impossible to independently audit.

In short, there is no getting to the bottom of the temperature-adjustment scandal, because the perpetrators have created no record to make it possible to figure out what they have done or to attempt to reproduce their work. 

Final question:  Is there any possibility that this is done innocently, as opposed to an intentional effort to engineer a fake record to support the cause of climate alarm?

OK, this is just one young guy doing some due diligence.  But the fact is, he has nailed the grand pooh-bahs with obvious data manipulation to achieve their desired result.  Do you expect any kind of response from the in crowd?  I don’t.

I’ll end with some conclusions from the Executive Summary:

The primary conclusion of the audit is however that the dataset shows exaggerated warming and that global averages are far less certain than have been claimed.

One implication of the audit is that climate models have been tuned to match incorrect data, which would render incorrect their predictions of future temperatures and estimates of the human influence of temperatures.

Another implication is that the proposal that the Paris Climate Agreement adopt 1850-1899 averages as “indicative” of pre-industrial temperatures is fatally flawed. During that period global coverage is low - it averages 30% across that time - and many land-based temperatures are very likely to be excessively adjusted and therefore incorrect.

A third implication is that even if the IPCC’s claim that mankind has caused the majority of warming since 1950 is correct then the amount of such warming over what is almost 70 years could well be negligible. The question then arises as to whether the effort and cost of addressing it make any sense.

Ultimately it is the opinion of this author that the HadCRUT4 data, and any reports or claims based on it, do not form a credible basis for government policy on climate or for international agreements about supposed causes of climate change.

Alarmist Claim Rebuttal October 8, 2018 Update

Alarmist Claim Rebuttal

Below are a series of rebuttals of the most common climate alarmists’ claims such as those made in the recently released Fourth National Climate Assessment Report.  The authors of these rebuttals are all recognized experts in the relevant scientific fields. The rebuttals demonstrate the falsity of EPA’s claims merely by citing the most credible empirical data on the topic.

For each alarmist claim, a summary of the relevant rebuttal is provided along with a link to the full text of the rebuttal, which includes the names and the credentials of the authors of each rebuttal.

Claim: Heat Waves are increasing at an alarming rate and heat kills.
Summary of Rebuttal

There has been no detectable long-term increase in heat waves in the United States or elsewhere in the world. Most all-time record highs here in the U.S. happened many years ago, long before mankind was using much fossil fuel. Thirty-eight states set their all-time record highs before 1960 (23 in the 1930s!).  Here in the United States, the number of 100F, 95F and 90F days per year has been steadily declining since the 1930s. The Environmental Protection Agency Heat Wave Index confirms the 1930s as the hottest decade.

James Hansen while at NASA in 1999 said about the U.S. temperature record “In the U.S. the warmest decade was the 1930s and the warmest year was 1934”.  When NASA was challenged on the declining heat records in the U.S, the reply was that the U.S. is just 2% of the world.  However, all 8 continents recorded their all-time record highs before 1980. 

Interestingly while the media gives a great deal of coverage to even minor heat waves to support the case that man-made global warming is occurring, the media tends to ignore deadly cold waves. But in actual fact, worldwide cold kills 20 times as many people as heat. This is documented in the “Excess Winter Mortality” which shows that the number of deaths in the 4 coldest winter months is much higher than the other 8 months of the year. The USA death rate in January and February is more than 1000 deaths per day greater than in it is July and August. Clearly, there is no problem with increased heat waves due to Climate Change.

Claim: Global warming is causing more hurricanes and stronger hurricanes.
Summary of Rebuttal

There has been no upward sloping long-term trend in the number and intensity of hurricane activity globally. The activity does vary year to year and over multidecadal periods as ocean cycles including El Nino/La Nina, multidecadal cycles in the Pacific (PDO) and Atlantic (AMO) favor some basins over others.

The trend in landfalling storms in the United States has been flat to down since the 1850s. Before the recent active hurricane season in the United States in 2017, there had been a lull of 4324 days (almost 12 years) in major hurricane landfalls, the longest lull since the 1860s.

Harvey in 2017 was the first hurricane to make landfall in Texas since Ike in 2008 and the first Category 4 hurricane in Texas since Hurricane Carla in 1961. There has been a downtrend in Texas of both hurricanes and major hurricanes. However, Texas is an area where Gulf Tropical Storms and hurricanes often stall for days, and 6 of the heaviest tropical rainfall events for the U.S. have occurred in Texas.  Harvey’s rains were comparable to many of these events. Claudette in 1979 had an unofficial rainfall total greater than in Harvey.

In Florida, where Irma hit in 2017 as a category 4 on the Keys, it came after a record 4339 days (just short of 12 years) without a landfalling hurricane. The previous record lull was in the 1860s (8 years). There has been no upward trend in hurricane intensity or landfalling frequency since at least 1900.

Claim: Global warming is causing more and stronger tornadoes.
Summary of Rebuttal

Tornadoes are failing to follow “global warming” predictions. Strong tornadoes have seen a decline in frequency since the 1950s. The years 2012, 2013, 2014, 2015 and 2016 all saw below average to near record low tornado counts in the U.S. since records began in 1954.  2017 rebounded only to the long-term mean. 2018 as of the end of May is ranking below the 25th percentile.

This lull followed a very active and deadly strong La Nina of 2010/11, which like the strong La Nina of 1973/74 produced record setting and very deadly outbreaks of tornadoes. Population growth and expansion outside urban areas have exposed more people to the tornadoes that once roamed through open fields.

Tornado detection has improved with the addition of NEXRAD, the growth of the trained spotter networks, storm chasers armed with cellular data and imagery and the proliferation of cell phone cameras and social media. This shows up most in the weak EF0 tornado count but for storms from moderate EF1 to strong EF 3+ intensity, the trend slope has been flat to down despite improved detection.

Claim: Global warming is increasing the magnitude and frequency of droughts and floods.
Summary of Rebuttal

Our use of fossil fuels to power our civilization is not causing droughts or floods. NOAA found there is no evidence that floods and droughts are increasing because of climate change. The number, extend or severity of these events does increase dramatically for a brief period of years at some locations from time to time but then conditions return to more normal. This is simply the long-established constant variation of weather resulting from a confluence of natural factors.

In testimony before Congress Professor Roger Pielke, Jr. said: “It is misleading, and just plain incorrect, to claim that disasters associated with hurricanes, tornadoes, floods, or droughts have increased on climate timescales either in the United States or globally. Droughts have, for the most part, become shorter, less frequent, and cover a smaller portion of the U.S. over the last century.?

“The good news is U.S. flood damage is sharply down over 70 years,” Roger Pielke Jr. said. “Remember, disasters can happen any time.... “But it is also good to understand long-term trends based on data, not hype.?

Claim: Global Warming has increased U.S. Wildfires.
Summary of Rebuttal

Wildfires are in the news almost every late summer and fall.  The National Interagency Fire Center has recorded the number of fires and acreage affected since 1985. This data show the number of fires trending down slightly, though the acreage burned had increased before leveling off over the last 20 years. The NWS tracks the number of days where conditions are conducive to wildfires when they issue red-flag warnings. It is little changed.

Weather and normal seasonal and year-to-year variations brings a varying number and extent of wildfires to the west every year and other areas from time to time. The 2016/17 winter was a very wet one in the mountains in the west, in parts of the northern Sierra, the wettest/snowiest on record).  Wet winters cause more spring growth that will dry up in the dry summer heat season and become tinder for late summer and early fall fires before the seasonal rains return.

2017 was an active fire year in the U.S. but by no means a record. The U.S. had 64,610 fires, the 7th most in 11 years and the most since 2012.  The 9,574, 533 acres burned was the 4th most in 11 years and most since 2015. The fires burned in the Northwest including Montana with a very dry summer then the action shifted south seasonally with the seasonal start of the wind events like Diablo in northern California and Santa Ana to the south.

Fires spread to northern California in October with an episode of the dry Diablo wind that blows from the east and then in December as strong and persistent Santa Ana winds and dry air triggered a round of large fires in Ventura County.

According to the California Department of Forestry and Fire Protection, the 2017 California wildfire season was the most destructive one on record with a total of 8,987 fires that burned 1,241,158 acres. It included five of the 20 most destructive wildland-urban interface fires in the state’s history.

When it comes to considering the number of deaths and structures destroyed, the seven-fold increase in population in California from 1930 to 2017 must be noted. Not only does this increase in population mean more people and home structures in the path of fires, but it also means more fires.  Lightning and campfires caused most historic fires; today most are the result of power lines igniting trees.  The power lines have increased proportionately with the population, so it can be reasoned that most of the damage from wild fires in California is a result of increased population not Global Warming. The increased danger is also greatly aggravated by poor government forest management choices.

Claim: Global warming is causing snow to disappear.

Summary of Rebuttal

This is one claim that has been repeated for decades even as nature showed very much the opposite trend with unprecedented snows even to the big coastal cities. Every time they repeated the claim, it seems nature upped the ante more.

Alarmists have eventually evolved to crediting warming with producing greater snowfall, because of increased moisture but the snow events in recent years have usually occurred in colder winters with high snow water equivalent ratios in frigid arctic air.

The eastern United States as an example has had 29 high impact winter snowstorms the last 10 years. No prior ten-year period had more than 10.

Snowcover in the Northern Hemisphere, North America and Eurasia has been increasing since the 1960s in the fall and winter but declining in the spring and summer. However, as NOAA advised might be the case, snowcover measurement methodology changes at the turn of this century may be responsible for part of the warm season differences.

Claim: Global warming is resulting in rising sea levels as seen in both tide gauge and satellite technology.
Summary of Rebuttal

This claim is demonstrably false.  It really hinges on this statement: “Tide gauges and satellites agree with the model projections.” The models project a rapid acceleration of sea level rise over the next 30 to 70 years.  However, while the models may project acceleration, the tide gauges clearly do not.

All data from tide gauges in areas where land is not rising or sinking show instead a steady linear and unchanging sea level rate of rise from 4 up to 6 inches/century, with variations due to gravitational factors.  It is true that where the land is sinking as it is in the Tidewater area of Virginia and the Mississippi Delta region, sea levels will appear to rise faster but no changes in CO2 emissions would change that.

The implication that measured, validated, and verified Tide Gauge data support this conclusion remains simply false.  All such references rely on “semi-empirical” information, which merges, concatenates, combines, and joins, actual tide gauge data with various models of the reference author’s choosing.  Nowhere on this planet can a tide gauge be found, that shows even half of the claimed 3.3 mm/yr sea level rise rate in “Tectonically Inert” coastal zones.  These are areas that lie between regions of geological uplift and subsidence.  They are essentially neutral with respect to vertical land motion, and tide gauges located therein show between 1 mm/yr (3.9 inches/century) and 1.5 mm/yr (6 inches/century rise). The great Swedish Oceanographer, Nils-Axel Morner, has commented on this extensively, and his latest papers confirm this ‘inconvenient truth’.

Furthermore, alarmist claims that “Satellites agree with the model projection” are false.  Satellite technology was introduced to provide more objective measurement of the sea level rise because properly adjusted tide gauge data was not fitting Alarmists’ claims.  However, the new satellite and radar altimeter data lacked the resolution to accurately measure sea levels down to the mm level. Moreover, the raw data from this technology also conflicted with Alarmists’ claims. As a result, adjustments to this data were also made - most notably a Glacial Isostatic Adjustment (GIA). GIA assumes that basically all land is rebounding from long ago glaciations and oceanic basins are deepening. The assumption is that this rebounding is masking the true sea level rise. Alarmists continue to proclaim that their models project a rapid acceleration of sea level rise over the next 30 to 70 years, when those same models have failed to even come close to accurately predicting the past 25 years.

Detailed Rebuttal and Authors: AC Rebuttal Sea Level

Claim:  Arctic, Antarctic and Greenland ice loss is accelerating due to global warming.
Summary of Rebuttal

Satellite and surface temperature records and sea surface temperatures show that both the East Antarctic Ice Sheet and the West Antarctic Ice Sheet are cooling, not warming and glacial ice is increasing, not melting. Satellite and surface temperature measurements of the southern polar area show no warming over the past 37 years. Growth of the Antarctic ice sheets means sea level rise is not being caused by melting of polar ice and, in fact, is slightly lowering the rate of rise. Satellite Antarctic temperature records show 0.02C/decade cooling since 1979. The Southern Ocean around Antarctica has been getting sharply colder since 2006. Antarctic sea ice is increasing, reaching all-time highs. Surface temperatures at 13 stations show the Antarctic Peninsula has been sharply cooling since 2000.

The Arctic includes the Arctic Ocean, Greenland, Iceland, and part of Siberia and northern Alaska. Because of the absence of any land mass in the Arctic Ocean, most of area lacks glaciers, which require a land mass. Thus, most of the Arctic contains only floating sea ice. Greenland, Iceland, northern Alaska, and northern Siberia contain the only glaciers in the general Arctic region.

Because of the absence of any land mass in the Arctic Ocean, most of the Arctic contains only floating sea ice.  Because the arctic ice is floating, it is subject to intrusians of warmer water under the ice during the natural multidecadal warm cycles especially from the North Atlantic, which thins the ice and reduces the ice extent in summer with its accompanying warmer air temperatures. Increased ice and colder temperatures are observed during cold water ocean cycles.

Arctic temperature records show that the 1920s and 1930s were warmer than 2000. Official historical fluctuations of Arctic sea ice begin with the first satellite images in 1979. That happens to coincide with the end of the recent 1945-1977 global cold period and the resulting maximum extent of Arctic sea ice. During the warm period from 1978 until recently, the extent of sea ice has diminished, but increased in the past several years. The Greenland ice sheet has also grown recently.

Claim: Rising atmospheric CO2 concentrations are causing ocean acidification, which is catastrophically harming marine life.
Summary of Rebuttal

As the air’s CO2 content rises in response to ever-increasing anthropogenic CO2 emissions, more and more carbon dioxide is expected to dissolve into the surface waters of the world’s oceans, which dissolution is projected to cause a 0.3 to 0.7 pH unit decline in the planet’s oceanic waters by the year 2300. A potential pH reduction of this magnitude has provoked concern and led to predictions that, if it occurs, marine life will be severely harmed - with some species potentially driven to extinction - as they experience negative impacts in growth, development, fertility and survival.

This ocean acidification hypothesis, as it has come to be known, has gained great momentum in recent years, because it offers a second independent reason to regulate fossil fuel emissions in addition to that provided by concerns over traditional global warming. For even if the climate models are proven to be wrong with respect to their predictions of atmospheric warming, extreme weather, glacial melt, sea level rise, or any other attendant catastrophe, those who seek to regulate and reduce CO2 emissions have a fall-back position, claiming that no matter what happens to the climate, the nations of the Earth must reduce their greenhouse gas emissions because of projected direct negative impacts on marine organisms via ocean acidification.

The ocean chemistry aspect of the ocean acidification hypothesis is rather straightforward, but it is not as solid as it is often claimed to be. For one thing, the work of a number of respected scientists suggests that the drop in oceanic pH will not be nearly as great as the IPCC and others predict. And, as with all phenomena involving living organisms, the introduction of life into the analysis greatly complicates things. When a number of interrelated biological phenomena are considered, it becomes much more difficult, if not impossible, to draw such sweeping negative conclusions about the reaction of marine organisms to ocean acidification. Quite to the contrary, when life is considered, ocean acidification is often found to be a non-problem, or even a benefit. And in this regard, numerous scientific studies have demonstrated the robustness of multiple marine plant and animal species to ocean acidification - when they are properly performed under realistic experimental conditions.

Claim: Carbon pollution is a health hazard.
Summary of Rebuttal

The term “carbon pollution” is a deliberate, ambiguous, disingenuous term, designed to mislead people into thinking carbon dioxide is pollution. It is used by the environmentalists to confuse the environmental impacts of CO2 emissions with the impact of the emissions of unwanted waste products of combustion. The burning of carbon-based fuels (fossil fuels - coal, oil, natural gas and biofuels and biomass) converts the carbon in the fuels to carbon dioxide (CO2), which is an odorless invisible gas that is plant food and it is essential to life on the planet.

Because the burning of the fuel is never 100% efficient, trace amounts of pollutants including unburnt carbon are produced in the form of fine particulates (soot), hydrocarbon gases and carbon monoxide.  In addition, trace amounts of sulfur oxides, nitrogen oxides and other pollutant constituents can be produced.  In the US, all mobile and industrial stationary combustion sources must have emission control systems that remove the particulates and gaseous pollutants so that the emissions are in compliance with EPA’s emission standards.  The ambient air pollutant concentrations have been decreasing for decades and are going to keep decreasing for the foreseeable future because of existing non-GHG-related regulations.

Detailed Rebuttal and Authors: AC Rebuttal Health Impacts


The well-documented invalidation of the “three lines of evidence” upon which EPA attributes global warming to human-caused CO2 emissions breaks the causal link between such emissions and global warming. {See: here and here)

This in turn necessarily breaks the causal chain between CO2 emissions and the alleged knock-on effects of global warming, such as loss of Arctic ice, increased sea level, and increased heat waves, floods, droughts, hurricanes, tornadoes, etc. These alleged downstream effects are constantly cited to whip up alarm and create demands for ever tighter CO2 regulation. EPA explicitly relied on predicted increases in such events to justify the Endangerment Finding. But as shown above, there is no evidence to support such claims, and copious empirical evidence that refutes them.

The enormous cost and essentially limitless scope of the government’s regulatory authority over GHG/CO2 emissions cannot lawfully rest upon a collection of scary stories that are conclusively disproven by readily available empirical data.

The legal criteria for reconsidering the Endangerment Finding are clearly present in this case. The scientific foundation of the Endangerment Finding has been invalidated. The parade of horrible calamities that the Endangerment Finding predicts and that a vast program of regulation seeks to prevent have been comprehensively and conclusively refuted by empirical data. The Petition for Reconsideration should be granted.

Delingpole: Hurricane Florence - Another Thing Not Caused by Climate Change

James Delingpole


Hurricane Florence is gathering strength as it approaches the Carolinas but not everyone is praying that it dissipates.

For Al Gore, Alec Baldwin, Jane Goodall, Catherine McKenna, Dave Matthews, John Kerry, Tom Steyer and all the other celebrity alarmists attending the Global Climate Action Summit in San Francisco over the next couple of days, this hurricane is like manna from heaven: the worse it gets, the better it is for their scaremongering cause.

Florence is currently a Category 4 but the more optimistic delegates will be hoping it makes Category 5 in the next 24 hours. If they’re really lucky, it will fulfill the Washington Post’s burning desire for winds so strong they merit an entirely new category:

In little more than a day, Hurricane Florence exploded in strength, jumping from a Category 1 to a Category 4 behemoth with 140 mph winds. This process - hurricanes intensifying fast - is both extremely dangerous and poorly understood. But new research says that as the climate continues to warm, storms will do it faster and more often, and in some extreme cases, grow so powerful that they might arguably be labeled “Category 6.”

As usual WaPo’s resident climate hysteric Chris Mooney is talking rubbish.

Roy Spencer puts him right on this blogpost: you can’t talk about worsening hurricanes when the trend shows the opposite:

Attendees of the conference are almost guaranteed to point to Florence as an example of what we can expect more of with global warming. But it’s curious how there hasn’t been a statistically significant increase in major hurricane strikes in the Carolinas (based upon NHC data), even assuming Florence hits as a Cat3+:


(The same is true in Florida.)

The 1950s was the stand-out decade for major hurricane strikes in the Carolinas, with Hurricane Hazel in 1954 doing major damage, even as far north as Toronto. Hazel’s destruction of Myrtle Beach, SC led to a massive rebuilding effort that transformed that community forever.

For sure, there has been an increase in hurricane damages over time, as infrastructure along the U.S. Gulf and Atlantic coasts has increased dramatically. There is simply more stuff for Mother Nature to destroy. But I doubt that the luminaries attending the Global Climate Action Summit this week can understand that increasing damages would occur even without any climate change.

Steven Goddard is on the case too - and has a few pertinent points to make. (He has also made an excellent video)

According to Roger Pielke Jr., east coast major hurricanes are down more than 60% over the past 50 years.


The US is just coming off the longest hurricane drought on record.



Meanwhile, the Washington Post is trying to pin responsibility for this weather event on Donald Trump:

Yet when it comes to extreme weather, Mr. Trump is complicit. He plays down humans’ role in increasing the risks, and he continues to dismantle efforts to address those risks. It is hard to attribute any single weather event to climate change. But there is no reasonable doubt that humans are priming the Earth’
“s systems to produce disasters.

But as Goddard (aka Tony Heller) notes, if it’s really true that U.S. Presidents have the power to create hurricanes, then the worst living offender is George W Bush. The really bad ones are quite beyond the reach of even the most astringent WaPo editorial…

If the Washington Post wants to blame presidents for hurricanes, then the top three perpetrators are Grover Cleveland, Rutherford B. Hayes and William Howard Taft.
