I know that many journalists who lived through the recent heat wave in the East think the event somehow validates global warming theory, but I’m sorry: It’s summer. Heat waves happen. Sure, many high temperature records were broken, but records are always being broken.

And the strong thunderstorms that caused widespread power outages? Ditto.

Regarding the “thousands”: of broken records, there are not that many high-quality weather observing stations that (1) operated since the record warm years in the 1930s, and (2) have not been influenced by urban heat island effects, so it’s not at all obvious that the heat wave was unprecedented. Even if it was the worst in the last century for the Eastern U.S. (before which we can’t really say anything), there is no way to know if it was mostly human-caused or natural, anyway.

“But, Roy, the heat wave is consistent with climate model predictions!”. Yeah, well, it’s also consistent with natural weather variability. So, take your pick.

For the whole U.S. in June, average temperatures were not that remarkable. Here are the last 40 years from my population-adjusted surface temperature dataset, and NOAA’s USHCN (v2) dataset (both based upon 5 deg lat/lon grid averages; click for large version):

Certainly the U.S drought conditions cannot compare to the 1930s.

I really tire of the media frenzy which occurs when disaster strikes...I’ve stopped answering media inquiries. Mother Nature is dangerous, folks. And with the internet and cell phones, now every time there is a severe weather event, everyone in the world knows about it within the hour. In the 1800s, it might be months before one part of the country found out about disaster in another part of the country. Sheesh.

This is What Summer Looks Like
By Dr. Anthony Lupo

It is early July, and we may finally at the end of a record setting heat wave. As usual, several scientists were quoted saying something along the lines of “this is what global warming looks like” [1]. They say that heat waves such as the one occurring this year are becoming more common and will happen more in the future. We also heard that this heat wave is unprecedented and more widespread than ever. While some sources cautioned that this singular event might not be attributed to global warming, it came with the typical caveat that these are the kind of events that are projected to occur in a warmer world.

The definition of an extreme event is one that a) occurs rarely or in the tail(s) of a statistical distribution, or b) an event that causes extreme physical burdens or economic hardship for humans and/or the environment. Since heat waves have an impact in real human terms, using the former definition would not be practical. Also, by the former definition, the frequency of heat waves would not change assuming a normal distribution regardless of how much climate changed.
While it is true that the globe today is warmer than it was in the early 20th century, the same cannot be said of the United States [2]. The 30-year periods encompassing the 1930s are as warm, or warmer than, the 1981-2010 means depending on the region [2].

If it is true that global temperatures today are warmer than those of the early 20th century, then more extremes could be likely using the latter definition above and assuming that, during both periods, the temperature distributions could be described as a normal distribution or “bell curve”.

Changes in variability would make the assessment of climate change more difficult. A temperature distribution shorter and fatter (taller and skinnier) than the normal, means the climate is more (less) variable. Thus, it is possible that under conditions of a modest rise in temperature over a 100 year period, for example, heat waves could become less frequent. This would indicate the modest temperature rise was accompanied by a reduction in temperature variability. This situation likely describes US temperatures over the last century or more, and the analysis below will support the conjecture. 

Then, in order to discuss the change in the frequency of extreme events, such as the recent heat wave, a benchmark or threshold could be chosen. In our region, the Missouri region, it makes sense to measure extreme heat waves using the number of consecutive 100 F maximums as one yard stick, since this would be a value most people in our region could agree is extreme. From June 26th to July 7th, or on 11 consecutive days, we experienced 100 F maximums in Columbia and Saint Louis.  How does this stack up against the record books?

Table 1 shows that this heat wave ranks as number six and two events of all-time for Columbia and Saint Louis, respectively. But, Table 1 also demonstrates that only two (one) top 10 heat waves have occurred in the last 20 years in Columbia (Saint Louis). In fact, for both cities, most of these occurred in the early part of the 20th century! Was this heat wave the most widespread? Certainly, Washington, DC has been hot as of late, but similarly, the number of extreme hot days there also occurred earlier in the 20th century [3]. Additionally, it can be inferred that the heat waves and droughts of the 1930s were as expansive or more so that today [4]. Finally, Table 1 shows that this year’s event can’t even lay claim to the earliest such event to occur in the summer season

It is still quite early in the summer of 2012, and the current heat wave has exacerbated the ongoing drought occurring over a large fraction of the US agricultural region. It is a serious event that bears watching, and this year has the potential to join the list of some of the most memorable drought years. But, it is not symptomatic of anthropogenic global warming.

Summer has arrived at Whistler Blackcomb, but the results of an amazing winter of snow (1382 cm’s of total snowfall) can still be experienced at the Summit of Whistler Mountain. With the Peak Chair now open daily for sightseeing as part of the Peak 2 Peak Alpine Experience, visitors can gain access into the alpine and walk from the Summit of Whistler down to the Roundhouse lodge through snow walled lined trails, with banks as high as ten metres tall, as seen in the photoes below (taken near the peak July 5, 2012).

Visitors can also experience the record breaking Peak 2 Peak gondola, and the stunning 360 degree views that it provides.

Unless you live in Seattle, you likely did not know that the National Weather Service just announced that the city endured its third coolest June on record. As much of America swelters through a heat wave, it’s not surprising that the usual suspects are telling everyone that it’s because of “global warming.”

I have a longtime friend, Ron Marr who has a Jack Russell Terrier and in a recent commentary for Missouri Life magazine, he wrote that, “Jack doesn’t believe in global warming in the least; he does not believe the recent atmospheric hellfire results from ozone holes or aerosol cans or giant leprechauns with a big magnifying glass. We share the same views on the topic and have discussed them often. Our considered opinion is that this streak of blazing nonsense stems from the fact that - to put it in scientific terms - it’s summer and the sun is hot.”

On July 3rd Seth Borenstein, a reporter for the Associated Press, a newswire service that has been reporting global warming lies for decades, wrote that “If you want a glimpse of some of the worst of global warming, scientists suggest taking a look at U.S. weather in recent weeks.”

IT’S SUMMERTIME, SETH! IT GETS HOT IN THE SUMMER!

It did not take long for the high priests of global warming to proclaim the current WEATHER to be CLIMATE. There’s a very big difference. Weather is what is occurring now while climate is measured in terms of centuries. It’s about trends and cycles.

It surely has been a hot summer thus far. Reuters reported that “more than 2,000 temperature records have been matched or broken in the past week as a brutal heat wave baked much of the United States.” The announcement was made by the National Oceanic and Atmospheric Administration (NOAA) on July 2nd.

Meteorologist Joe Bastardi took another reporter to task for coupling the heat wave with global warming, pointing out that “The US is less than 10% of the globe” while ignoring that “Scandinavia had coldest June on record and that Australia is having a bad winter.”

What we should all know by now is that the Warmists all use trickery to advance their hoax.

The simple fact is that heat waves are nothing new. In 1936 a North American heat wave was the most severe in the modern history of the continent. It occurred in the middle of the Great Depression, killing more than 5,000 Americans and desiccating vast amounts of crops. To put it in perspective, there were no home air conditioning appliances at the time. People depended on fans to circulate the air.

The sun surely is hot, but its heat - solar radiation - has not been sufficient to avoid cyclical ice ages and short term periods of intense cold because the sun itself goes through cycles of increasing and diminishing solar radiation.

There was a “Little Ice Age” that lasted between 1550 and 1850. Temperatures dropped to the point that the Thames River in England froze over and “frost fairs” were held on its surface. It was felt through Europe and parts of North America.

Writing in The Wall Street Journal, Matt Ridley noted that “Over the past million years, it has been as warm as this or warmer for less than 10% of the time, during 11 brief episodes known as interglacial periods,” adding that “this warm spell is already 11,600 years old, and it must surely, in the normal course of things, come to an end.”

The average length of interglacial periods is 11,500 years.

In the 1970s, prior to the global warming hoax, many scientists were convinced that a new ice age had begun. In January 2012, a member of the Russian Academy of Sciences, Habibullo Abdusamatov, predicted that the next ice age will begin in 2014 and will last at least two centuries. Regarding the timing, he could be right. He could be wrong. One thing is sure. The Earth is overdue another ice age.

My friend, Robert W. Felix, the author of “Not by Fire, But by Ice”, is an expert on ice ages and magnetic reversals. It is the latter that accompanied mass extinctions such as the dinosaur’s fate and many other species at the end of the Cretaceous period. In ice ages, the Earth’s water doesn’t disappear, it turns to ice. The current growth of the planet’s glaciers is an indicator of what is actually occurring.

Another indicator, of course, is the sun. On January 29, 2012, writing in the Daily Mail, a British newspaper, David Rose noted that “The supposed ‘consensus’ on man-made global warming is facing an inconvenient challenge after the release of new temperature data showing the plane has not warmed for the past 15 years.”

“After emitting unusually high levels of energy throughout the 20th century, the sun is now heading towards a ‘grand minimum’ in its output, threatening cold summers, bitter winters, and a shortening of the season available for growing food. Solar output goes through 11-year cycles, with high numbers of sunspots seen at their peak.”

“We are now at what should be the peak of what scientists call ‘Cycle 24’...but sunspot numbers are running at less than half those seen during cycle peaks in the 20th century.” Oddly, despite the obvious and documented effect of the sun on the planet’s average temperature, there remain scientists who are unconvinced of its essential role. Only a relative few even understand the role of magnetic reversals on the planet’s history.

Actually, the diminishing number of sunspots has been known for a while. In June 2010, Stuart Clark, writing in The New Scientist, observed that “For the past two years, the sunspots have mostly been missing. Their absence, the most prolonged for nearly a hundred years, has taken even seasoned sun watchers by surprise.”

The obvious often catches people by surprise. The last Ice Age came on very swiftly and the next is likely to do so as well. In the meantime, the current heat wave will capture everyone’s attention.

The recent thunderstorm wind event which caused widespread wind damage from Ohio to the mid-Atlantic coast has, rather predictably, led to claims that global warming is the root cause.

Known as a “derecho”, these events are indeed uncommon, but have always been around: the term was originally coined in 1888 in a study of thunderstorm wind damage which occurred in 1877.

In fact, one of the most famous events occurred when global temperatures reached a minimum, back in the 1970’s. Known simply as “The Storm”, it occurred 35 years ago today, on July 4, 1977. There were widespread blowdowns of trees (see the photo, above). Even though the event occurred over relatively unpopulated areas in Minnesota, Wisconsin, and Michigan, the highest recorded wind speed was an astonishing 115 mph, officially recorded with an airport anemometer.

Compare that to the derecho event of last week, which occurred over heavily populated areas: the highest measured wind speed in the extensive list of reports at the Storms Prediction Center was only 92 mph, and even that was on a home weather station, and so is unofficial.

So, why all the fuss over last weeks storm? Because it didn’t hit flyover country. Tens of millions of people were affected, and millions went without power.

Of course, those affected included many journalists, so it is only natural that they would speculate (and seek out experts to speculate) about the sinister causes of such an event.

Surely the silliest comment I saw came from Bill Nye, “The Science Guy”, who stated: “...We had a 30-degree temperature drop in Maryland and Virginia this weekend, in just - in a half-hour. These are consistent with climate models.”

First of all, such temperature drops occur routinely with the passage of mid-latitude thunderstorms. Secondly, climate models predict no such thing anyway. If “The Science Guy” gets it this wrong, how can I trust him on anything else?

Now that the mainstream media are hyperventilating over global warming being responsible for the heat wave, fires and thunderstorms hitting the US, it is a good time to check if they are applying the same science they used to explain winter cold snaps, like the one we saw just 2 years ago.

If they were serious, you’d at least think their science would remain consistent when explaining weather extremes. Anything else, after all, is just quackery.

Two years ago, the AP and scientists blamed the unusually cold winter weather on “natural variability”; they began:

Beijing had its coldest morning in almost 40 years and its biggest snowfall since 1951. Britain is suffering through its longest cold snap since 1981. And freezing weather is gripping the Deep South, including Florida’s orange groves and beaches.

Whatever happened to global warming? experts say the cold snap doesn’t disprove global warming at all ‘It’s part of natural variability,’ said Gerald Meehl, a senior scientist at the National Center for Atmospheric Research in Boulder, Colo. With global warming, he said, ‘we’ll still have record cold temperatures. We’ll just have fewer of them.’

Scientists say man-made climate change does have the potential to cause more frequent and more severe weather extremes...and even cold spells.”

The AP then quoted scientists to explain the cause of the cold snap of 2010, saying that it was just a “big outbreak of Arctic air over populated areas of the Northern Hemisphere”, and then went on to provide the details about natural variability, which of course is reasonable.

But to explain the current 2012 heat wave near DC, they completely abandoned the reasonable science and went off and blamed CO2 witchcraft and Big Oil sorcerers summoning a heat wave.

So it’s up to us to use the rest of the AP’s 2010 story to explain the heat wave, changing only a few words:

“We basically have seen just a big outbreak of Arctic tropical air’ over populated areas of the Northern Hemisphere, Arndt said. ‘The Arctic tropical air has really turned itself loose on us.’

In the atmosphere, large rivers of air travel roughly west to east around the globe between the Arctic and the tropics. This air flow acts like a fence to keep Arctic tropical air confined.

But recently, this air flow has become bent into a pronounced zigzag pattern, meandering north south and south north. If you live in a place where it brings air up down from the south north, you get warm cold weather. In fact, record highs lows were reported this week in Washington state and Alaska West Coast.

But in the eastern United States, like some other unlucky parts of the globe, Arctic tropical air is swooping down in from the north southwest. And that’s how you get a temperature of 3 104 degrees in Beijing Washington DC, a reading of minus-42 +104 in mainland Norway Norfolk, and 18 inches of snow rain in parts of Britain the South, where a member of Parliament Congress who said the snow heat ‘clearly indicates a cooling warming trend’ was jeered by colleagues.

The zigzag pattern arises naturally from time to time, but it is not clear why it’s so strong right now, said Michelle L’Heureux, a meteorologist at the Climate Prediction Center of the National Oceanic and Atmospheric Administration. The center says the pattern should begin to weaken in a week or two.

Jeff Masters, director of meteorology for Weather Underground, a forecasting service, said he expects more typical winter summer weather across North America early next week.

That will be welcome news in the South, where farmers have been trying to salvage millions of dollars’ worth of strawberries and other crops.

Why Borenstein and the quack scientists he interviewed didn’t use the same 2010 cold-snap science to explain the general atmospheric dynamics behind the current heat is sort of a mystery. Now that we are dealing with heat, they are blaming it all on CO2 without even citing a single paper to back it up.

So what are we left with? We have to assume that it’s a few fringe charlatans trying to fan the flames of fear. It’s as sad an example of sham science as you’ll ever find.

For these catastrophe-mongers, warm weather in the winter means global warming, cold weather in the winter also means global warming, heat in the summer of course means global warming, and so does cold in the summer. It is nothing more than the irresponsible perpetuation of an increasingly obvious fraud.
