The Archibald Prize
By David Archibald
In last Thursday’s West Australian, John Connelly of The Climate Institute said that I am destroying the environment. I have written a reply. Do read on.
John Connor of The Climate Institute says that my boat, my car and I are destroying the environment. My work says the opposite. The more carbon dioxide you put into the atmosphere, the more you are helping all plants on the planet to grow, and of course that makes you a better person. Virtue is in direct proportion to your carbon dioxide output. What of the temperature, you ask? Carbon dioxide is a greenhouse gas, but the effect is strongly logarithmic. The first 20 ppm achieves 1.5 degrees of heating, but it takes more than another 400 ppm to equal that. By the time we get to the current level of 384 ppm, carbon dioxide is tuckered out as a greenhouse gas. From here, every 100 ppm extra may be worth 0.1 of a degree.
So how does the IPCC achieve 5 degrees of heating from a doubling of the pre-industrial level of carbon dioxide to 560 ppm? They do it by cheating. Their computer models are written so that a little bit of carbon dioxide-caused heating puts more water vapour in the air. Water vapour is the major greenhouse gas, so they have the heating compounding away until they get a number that will melt icecaps, kill polar bears and all the other effects of their apocalyptic visions. Their view of the Earth’s climate is that it is tremendously unstable, prone to thermal runaway at the slightest provocation. In fact it is the opposite, a buffered system that dampens disturbances. Tropical seas can’t get warmer than 31 degrees because they start evaporating too rapidly to get any hotter. Similarly, high level tropical clouds part to vent radiation to space. The Earth is just about perfect for sustaining equable living conditions over a good proportion of its surface
What is strange is that the wailing of the global warming proponents is in the face of a temperature record that does not support their theory. Peak global temperature was in 1998 and we have had ten years of cooling since. The satellite record shows that the temperature of the Southern Hemisphere has been flat for the last 30 years. The Earth’s failure to warm has become quite annoying to the global warmers, and signs of cognitive dissonance are appearing in their camp. Surely a few more years of cooling will leave only the true believers in their misanthropic ideology, and the truly idiotic. Or is that moment with us now?
Can cooling continue, or is climate just a random walk? Not only will it continue, substantial cooling next decade is in the bag based on current solar behaviour. There is a good correlation between solar cycle length and the temperature over the following solar cycle. Long solar cycles cause lower temperatures. The classic case is the Dalton Minimum between 1796 and 1820. This was a time of crop failures in Europe and the US, and of the Thames freezing over in winter, caused by the weak amplitude of Solar Cycles 5 and 6. Solar cycles are normally 11 years long. Solar Cycle 4 which preceded the Dalton Minimum was a long one at 13.6 years. We are currently near the end of Solar Cycle 23, which is already 12 years long and showing no signs of finishing this year. It is already two and a half years longer than the one that preceded it. With 0.7 degrees of cooling for every extra year of solar cycle length, we already have 1.7 degrees of cooling in the bag for the mid-latitudes. Read more of this excellent reply here.

Very Active Tornado Season Another Classic La Nina Effect
By Joseph D’Aleo, CCM
The winter and spring brought heavy, in places all-time record snowfall, flooding, and now an active tornado season. All of these are classic strong La Nina phenomena. Brush fires now ablaze in Florida are is also a common springtime La Nina hazard. Almost daily tornadoes have been in the news with 910 reported to date (as of 5 am Tuesday). 97 deaths have also been reported. We have not had a superoutbreak (yet) as we did in 1974 (The Great Superoutbreak) or 1965 (Palm Sunday Outbreak), but a lot a very active days. Given the pattern with a strong suppressed jet stream and lots of high latitude blocking more active days can be expected.
The most fatalities from tornadoes occurred in the 1920s (peak 1928) (source NSSL). In recent decades, deaths were less with the exception of the two years with SUPER OUTBREAKS, 1965 and 1974 (both years coming off La Nina winters, in 1974, one of the strongest)
See larger graph here.
See this entire story with more on those superoutbreaks here.
Don’t let anyone tell you this is the result of global warming. This May has with the exceptions of a few pockets, been a cold month so far thanks to high latitude blocking and a suppressed jet stream. With that forecast to continue, expect more widespread unseasonably cool temperatures and severe weather ahead.

That Darned Water Vapor
By Craig James, WOOD-TV Blog
If you’ve read many of my past posts, you may remember that the main reason I (and many other meteorologists) disagree with the computer model forecasts of how much warming will occur due to an increase in CO2 is because of how those models handle water vapor. In this post written over a year ago, I included the following statement from the IPCC:
“Water vapour feedback continues to be the most consistently important feedback accounting for the large warming predicted by general circulation models in response to a doubling of CO2. Water vapour feedback acting alone approximately doubles the warming from what it would be for fixed water vapour (Cess et al., 1990; Hall and Manabe, 1999; Schneider et al., 1999; Held and Soden, 2000). Furthermore, water vapour feedback acts to amplify other feedbacks in models, such as cloud feedback and ice albedo feedback. If cloud feedback is strongly positive, the water vapour feedback can lead to 3.5 times as much warming as would be the case if water vapour concentration were held fixed (Hall and Manabe, 1999).”
Now, a new study published in the May 8 Science Daily, admits that when computer models have tried to simulate the climate in the Antarctic over the past 100 years, those simulations have been too warm . The reason given is: “The error appeared to be caused by models overestimating the amount of water vapor in the Antarctic atmosphere.” In fact, the models over estimated the amount of warming by a factor of exactly 3.5 (at least that IPCC forecast was correct). The simulation was for 1.4 degree F warming and it has turned out to be just 0.4F.

The authors add that “model projections of future Antarctic climate may be unreliable.” No kidding! They also state that “computer models are accurately simulating climate for the other six continents.” Oh really? How many models have forecast there would be no warming from 1998-2008? I’ll bet it is all because of how they handle that darned water vapor. Read Craig’s full blog here.

Has Big Media Global Warming Bias Begun to Endanger the Public?
By Bill Tate, The American Thinker
When Maine officials tried to warn residents of the dangers of this winter’s near-record snowpack, Big Media slanted the story, hampering efforts to warn folks of the danger. “This winters [sic] near-record snowfall has created a flood potential that is above normal,” began a news advisory released by the Maine River Flow Advisor Commission on March 6th.
“Statewide water content readings from this week’s snow survey are some of the highest since 1969, the ‘snow season’ of record, and in some locations higher than the record.” In case there was any doubt, the banner headline on the release reads: “Spring Flood Potential Elevated Due to Near-Record Snowfall.”
However, the lead in the Associated Press story in the next day’s edition of the major regional daily, the Boston Globe, downplayed the threat posed by the snowpack, referring to it as just “above-average,” and shifting the emphasis to concern about an approaching storm. “The National Weather Service says weekend rain could cause some flooding of streets and small streams.”
Why did the AP and the Globe de-emphasize Maine officials’ snowpack warning, especially when doing so endangered the property and safety of the public they are supposed to serve?
The Globe is owned by the New York Times Company. Both the Times and the Associated Press are heavily invested in the myth of Global Warming, or—as I like to call it—Global Warning. Record snowpack means higher than normal amounts of snow, colder than usual temperatures, or both. None of which readily fits into the MSM’s chosen story line that mankind is giving Mother Nature a fever. Big Media’s Global Warning bias has largely remained in the realm of theory; now it has begun to endanger people’s lives and property in real time. The AP and the Globe had the choice of reporting a truly inconvenient truth—for them—or of perpetuating Global Warning, of facilitating officials’ efforts to protect the public or advancing their ideological agenda. Why are we not surprised by the decision they made? Read more here.

Blizzards Force South African Adventurer to Turn Back
By Tony Carnie , IOL
South African snow adventurer Correne Erasmus-Coetzer has been forced to abandon her dream of becoming the first African woman to cross the icy continent of Greenland on foot. The dream came to an end this week when the expedition of nine men and women came up against a ferocious wind and snow storm, and rapidly dwindling food supplies, as they approached the quarter-way mark of their 550km slog from the east to west coast of Greenland, across the Arctic Circle. Erasmus-Coetzer was hoping to create awareness about global warming and raise money for the Durban-based Wilderness Leadership School.
In a satellite phone message posted on her on expedition website, a disappointed Coetzer said the future of the journey had been in the balance for several days, but a decision was taken on Wednesday to turn back. Erasmus-Coetzer said the conditions in Greenland were worse than anything she had experienced during previous expeditions to the North and the South Poles.
It was a bit like “walking in milk” she said, explaining that the sky was full of snow and this made it impossible to distinguish between the horizon and the sky.For nearly three days the expedition had been snowed-in by icy, gale-force winds which tore against their tents.
Read more here.
This was the second adventurer, an Australian, that had to abandon their trip through Greenland due to cold and snow this week. See this tale.
And now yet a third tale of a failed expedition here. May 3rd: Friday night we have had contact with Greenland. The expedition Circle 66 is caught in extreme bad weather, Petoraq wind with a speed of 120 km’s per hour and a big amount of snow drift . Also eight of the twelve team members have caught a virus (throwing up). Because of this the expedition leader decided to cancel the trip. All team member were brought to the base with helicopters where they started the expedition. We are all very touched by this decision, but the risk to stay on the ice
was too big. Everybody is safe at moment and is doing well considering the circumstances.”
