Humans can adapt to live in locations where the monthly average is over 40°C, and as low as -50°C. That’s a 90°C range. The world has warmed by 0.9°C in 100 years (or less, depending on adjustments). This warming was so dangerous that global population only expanded from 1.7 to 7 billion.
Now, if the IPCC are right, we might heat up by another half a degree by 2100 — shifting those extremes from -49°C up to 41°C.
Prof. Andy Pitman, one of Australia’s leading climate scientists, responds to this risk with all the usual careful analysis we’ve come to expect from mainstream climate experts. Here’s another “children won’t know what snow is” type of Global Panic quote:
“I expect by 2050 … people just don’t go outside,”
– Professor Andy Pitman, director of the ARC Centre of Excellence for Climate System Science at UNSW.
So that’s the end of golf, surfing, and picnics then. Somewhat confusingly, he also said (in the same interview) that we won’t necessarily notice that extra warmth: “… because humans acclimatise to heat quite quickly”. This is what 95% certainty looks like in 2015, ladies and gentlemen — abject panic and [...]
Yet more evidence that there is no relationship between CO2 and cyclones, hurricanes, and typhoons. This paper from 2012 tests the theory that global warming made storms more severe and tried to find any effect on typhoons hitting Japan that could be linked to climate change since 1980.
There has been no increase in “super typhoons”. The typhoon season is not longer, nor is it delayed in starting. There has been no change in intensity. The wind speeds are not increasing. The minimum pressure is pretty much the same.
CO2 appears to influence storms in simulated worlds, but not so much in the real one. There is no sign of more severe storms in Australia, New Zealand or the South Pacific either. Nor is there any pattern in the Global Energy indicies, US Hurricanes, US Tornadoes either.
When will scientists and reporters make sure that their audiences know that?
The authors conclude:
“The results suggest that typhoons have not been influenced by global warming. In conclusion, global warming has not significantly changed the characteristics of typhoons, and there is no close relationship between the two.”

So far 24 are confirmed dead in Vanuatu, a figure that seems likely to rise. About 100,000 are homeless, according to the local Oxfam director, which, if accurate, is an awful lot in a country of 270,000. There is no doubt the nation needs help.
Despite the pressing need to solve immediate problems, the predictable claims are already starting. How many journalists will bother to check these claims against the history of cyclones in Vanuatu? Accuweather lists a lot, including one in 1951 that killed 100 people when CO2 levels were just 311ppm. In 1987 another storm killed 48.
President Baldwin Lonsdale is blaming “climate change”.
Pacific nations regard themselves as at the frontline of climate change, given many are low-lying islands dangerously exposed to rising sea levels, and Lonsdale said changing weather patterns were partly to blame for the destruction.
“Climate change is contributing to the disaster in Vanuatu,” Lonsdale told reporters in Japan, saying rain had been unusually heavy this year.
Even President Hollande, host of the Paris UNFCCC later this year, is milking this disaster: “…the cyclone “is a new cry for the international community to take seriously its responsibility in the fight [...]
UPDATE: Data for Middle Percy Island has disappeared from the BOM site, but Jennifer Marohasy kept a copy. (I’m sure the BOM will be grateful!) The Courier Mail has an article quoting Jennifer.
The facts on Cyclone Marcia: the top sustained wind speed was 156 km and the strongest gust 208 km/hr. These were recorded on Middle Percy Island in the direct path before it hit land and apparently rapidly slowed. The minimum pressure recorded after landfall was 975Hpa. BOM and the media reported a “Cat-5″ cyclone with winds of 295 km/hr. To qualify as a Cat 5, windspeeds need be over 280km/hr. The UN GDACS alerts page estimated the cyclone as a Cat 3.
The damage toll so far is no deaths (the most important thing), but 1,500 houses were damaged and 100 families left homeless. It was a compact storm, meaning windspeeds drop away quickly with every kilometer from the eye, so the maps and locations of the storm and the instruments matter. See the maps below — the eye did pass over some met-sites, but made landfall on an unpopulated beach with no wind instruments. It slowed quickly thereafter. The 295 km/hr wind speed was [...]
A major stormfront in NSW has dropped 170mm on rain on Ulladulla, ploughed down trees, drove waves 8m high onshore, and put the airport underwater in Sydney. It has carpeted the Blue Mountains in 20cm of snow. 30,000 homes lost electricity and 60 people were stuck in a train for two hours. This time last year the region was burning. Amazing photos at the Daily Mail.
Proof of man-made global warming…

Doreatha Mackellar 1908:
I love a sunburnt country, A land of sweeping plains, Of ragged mountain ranges, Of droughts and flooding rains.
We hope everyone is safe.
There are waves piling on waves in the weather.
A new press release tells us that there have been an “exceptional” number of weather extremes in summer.
Weather extremes in the summer — such as the record heat wave in the United States that hit corn farmers and worsened wildfires in 2012 — have reached an exceptional number in the last ten years. Human-made global warming can explain a gradual increase in periods of severe heat, but the observed change in the magnitude and duration of some events is not so easily explained.
Heatwaves lend themselves to headlines. Not only are they scary, but for climate researchers at a loose end, there are 1,000 flavors of wave to comb through. Is that a 3 day, 4 day or 7 day wave you are interested in? Is the cut-off 40C, 38C, 35C or a flexible percentile anomaly above the monthly average? Is it a statewide average, a national record, or a hot week in Houston? Shall we analyze that in seasons, by months, years, or part thereof? The combinations and permutations can keep a supercomputer up late at night. There’s a whole field of cherry trees ripe for the plucking.
Remember how CO2 is supposed to cause warmer winters, and warmer nights? Well now CO2 also produces cold snaps. No matter what weather you get, there is a citation to blame CO2. Nature (the formerly great science journal) and Northeastern University have produced another permutation of outputs from models we know are broken.
The first line in the press release is false and smugly so: “most scientists — 97 percent of them, to be exact — agree that the temperature of the planet is rising and that the increase is due to human activities….” 10 seconds on Google would have shown — 60% of geoscientists and engineers don’t agree.
If Kodra and co were trying to be accurate, they could have said “97% of annointed climate scientists agree… “. If they were trying to be scientific, of course, they wouldn’t mention a consensus at all. If they had good evidence, they’d talk about that instead.
They dug deep in The-Book-of-Cliches for the press release. Strip away the advertising spin and I think this is the nub of the work:
“While global temperature is indeed increasing, so too is the variability in temperature extremes. For instance, while each [...]
The CSIRO decided to leave out some information about the state of our climate in their State of the Climate Report CSIRO.
CSIRO published these “Fast Facts” in bold. I’m publishing the things they didn’t say, but could have, in points in between.
Fast Facts from the CSIRO and BOM “Australia’s climate has warmed by 0.9°C since 1910, and the frequency of extreme weather has changed, with more extreme heat and fewer cool extremes.” The CSIRO-BOM team could have said: Scientifically, extreme weather measures are lousy indicators. They’re noisy and not very meaningful. They are however useful for getting newspaper headlines. It depends on what your aim is… Australia’s had extreme hot days for as long as we’ve been measuring the temperature. Charles Sturt recorded 53C in 1828 which seems fairly extreme. Thomas Mitchell did it too in 1845 and are many others (see the map below, check Trove, ask the BOM — no don’t ask the BOM). The records prior to 1910 seem to have gone down the memory hole, but if the BOM and CSIRO were trying to give Australians a true sense of the state of our climate perhaps Australians might like to know that [...]
The pause in global warming is so crippling, so crucial, that scientists will go to extremes to find any excuse to issue something that combines the magic terms “no pause” and “extreme temperatures”. This is the winning combination in climate bingo. But marvel how far these researchers have to stretch to get there.
Gaze upon Seneviratne et al (UNSW) declaring that there is no pause in the trend of “extreme hot temperature days”. Watch the pea (or rather peas).
Globally, on average, regions normally expect around 36.5 extremely hot days in a year. The observations showed that during the period from 1997-2012, regions that experienced 10, 30 or 50 extremely hot days above this average saw the greatest upward trends in extreme hot days over time and the area they impacted.
The consistently upward trend persisted right through the “hiatus” period from 1998-2012.
If the world was warming, they wouldn’t bother with this strained nonsense, would they? They are talking about 15 year trends in air over land, in summer, on the hottest 10% of days.
Seneviratne et al acknowledge the pause in global temperatures. Therefore the models, and the theory is wrong. Every other incidental trend in smaller markers [...]
Another round of government-funded PR went out a couple of weeks ago, across the obedient Pravda-media. It told us about another meaningless “record” that was probably not a record, and wouldn’t tell us whether man-made warming was the cause, even if it was. Not a single journalist had the wherewithal, nous or intellectual honesty to search the Internet looking for a different point of view. Though, in their defense, how could they have guessed that Prof David Karoly wouldn’t know about the UAH satellite program to measure temperatures? (It has only been running since 1979.)
This below, are the 12 month averages over Australia by satellite. Graphed at Kens Kingdom by Ken Stewart, with no doctorate in climatology and no government funds.
In the troposphere over Australia it was a hot year but not a record.
For the third time this year we’ve been hit with claims of a “hottest ever” record that doesn’t tell us anything about the climate, but does reveal a lot about the sick state of government funded science, corrupted, decrepit, and so far from being scientific it might as well be run by Greenpeace. If the government stopped funding climate science entirely, climate [...]
