43% fewer cyclones is a good thing, right?
Using the same ClimateChangeTM reasoning the UN Secretary General uses, it’s clear fossil fuel use dramatically reduces the number of dangerous cyclones in the Northern Indian Ocean. A new study revealed an astonishing 43% decline in the number of equatorial cyclones in recent decades (1981–2010) compared to earlier (1951–1980) when fossil fuel use was vastly reduced. The researchers also point out that this is especially interesting because “the Indian Ocean basin has warmed consistently and more than any other ocean basin.” Could it be that warmer oceans are not necessarily terrible?
The study looked at the Low-Latitude Cyclones (LLC) that originate near the equator in the North Western Indian ocean. These LLC’s are smaller but intensify more rapidly than other cyclones, giving people less time to prepare. In 2017 LLC Ockhi caught forecasters off guard, travelled 2,000 kilometers and caused the deaths of 884 people in Sri Lanka and India.
This is obviously a benefit for the billion poor people who live around the Bay of Bengal. The researchers however, for some reason do not call for an increase in fossil fuel emissions. Instead they looked for and found […]
Children won’t know what a cyclone is
Hurricane activity, after human emissions and CO2 levels reach highest ever recorded, is now close to lowest ever recorded.
Based on a trend starting in 2019 major hurricanes may disappear entirely by 2035. What if Net Zero means “no cyclones”?

If the situation were flipped, try to imagine that the media would not write headlines like “Hurricanes near highest level ever recorded” and “Signs of Climate change seen in near record hurricane season”, or “Worst Cyclone season for thirty years!

The voters smacked the Greens yesterday, so today the Greens smack the voters. Richard Di Natale, Green Chieftain, blames the recent spate of storms and fires for the governments failure to change the global weather.
The Australian
The Greens have blamed the federal government’s failure to address climate change for a cyclone and bushfires which have ravaged communities across Australia over the past 48 hours.
Cyclone Marcus has swept across the Northern Territory, bringing down power lines and hundreds of trees in what Chief Minister Michael Gunner described as the biggest storm to hit the Top End in 30 years.
In Tathra on the NSW South Coast, at least 70 properties have been destroyed, while thousands of hectares of farmland, livestock and 18 homes have been lost in four blazes which were started by lightning strikes across South West Victoria.
In an anti-coal speech in the Senate today, Greens leader Richard Di Natale said the government had been doing “everything it can to slow this country’s transition to renewable energy”.

Cyclones down the memory hole?
July 1935, Click to enlarge | Trove
A weak tropical cyclone has formed off the Solomon Islands, and the BOM is reporting that there has never before been a July cyclone in the Queensland region. But Warwick Hughes has already posted up details showing that there have been quite a few cyclones in July. The cyclone is hardly extraordinary, and certainly not “historic”, but what about the BOM?
Forecaster David Grant on the ABC:
“We’ve never had a July tropical cyclone in the Queensland region before.
Australia has only had one other officially declared July cyclone, which formed off Western Australia in 1996.
The official tropical cyclone season runs from November 1 to April 30.”
The July cyclone “first” scores headlines in both The Australian and The Courier Mail. “Queensland weather forecasters record first cyclone in July “. But it’s wrong. Commenter Siliggy on Warwick Hughes site found a HardenUp link listing cyclones and storms in Queensland. Some of the older July cyclones listed below may not qualify as “cyclones” under the new scale, but some clearly did — and rather than being far to the north near […]
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 […]
Get ready:
“Australia records its third quietest start to the cyclone season in 50 years.” ABC news, Jack Kerr
Bravo, I thought. ABC covers a good-weather story… but no, lo, for the climate oracles tell us this is ominous and bigger nastier storms are coming. Be afraid!
This weather is weird?
There have only been four occasions since the mid-1960s when cyclones haven’t crossed the mainland before February.
Only four. Golly! This year is almost as “bad”as the worst of the prehistoric era, i.e. ’68, ’80, ’88).
It’s not like the good ol’ days — when people used to get decent cyclones all the time:
Back in 1870, when Cairns started life as a gold port, four to five severe cyclones would hit the Queensland east coast every decade. By 2010, that average was down to less than two.
Lucky them.
To see the effect of man-made global warming, look hard at this graph below. Spot the… trend.
A high bar means a long slow quiet start to the cyclone season.
At the start in 1964 CO2 was a wonderful 320ppm. Now it is at 400ppm and obviously (when seen through a computer […]
UPDATE: Cyclone Ita is now Category 5 bearing down on Cooktown in North Queensland, the radars will show it soon. 175km NNE of Cooktown. Winds up to 300km /hr. 931 hPa. See The BOM warnings. Thoughts for those in the path. (It’s clearly visible in the satellite image on the radar link).
——————————————————————————–
A new paper by Andrew Dowdy tells us that from 1980 to 2013 the incidence of tropical cyclones around Australia has been falling. If CO2 is influencing cyclones around Australia, presumably this implies we should burn more coal.
Those convinced about the power of CO2 will point out that the models predict an increase in intensity, not frequency. To that end, I say: see the BOM graph below. Note the red bars marked “severe”. Then tell yourself that the science is settled and we should spend billions to change those trends. The BOM say “the number of severe tropical cyclones (minimum central pressure less than 970 hPa) shows no clear trend over the past 40 years.”
Interestingly Callaghan et al 2010 goes back all the way to 1870. It finds the trend of severe land-falling cyclones has fallen by a whopping […]
A new paper suggests there is an “unprecedentedly” low number of tropical cyclones around Australia at the moment. (How much should we spend to avoid this dreadful outcome I wonder?)
I am a little skeptical of how we can be so sure of the cyclone activity in, say, the year 900 AD. But nonetheless, the study is worth a look. Haig et al took stalagmites from two places in Australia (Chillagoe, Qld, and Cape Range, WA) and got very nice long year-by-year records of 18O and 16O data. They calibrated these against observational instrumental records — though I note these are but a tiny 20 years of data (1990 – 2010), and that during a period described by mainstream climate science (cough) as “unprecedented”.
Assuming that it is possible to pick apart normal rain and cyclonic rain, and that cyclone activity did not just shift to be more than 400 km away (where these stalagmites won’t record the cyclones) then it does appear that there are usually more cyclones in Australia than now. Note the top graphs are the WA site which go back to 500AD, and the lower pair are the QLD graphs “only” going back to 1300AD. Both […]
Catastrophic killer storms are coming!
‘The Australian Greens say Tropical Cyclone Yasi is a “tragedy of climate change”.’
“DESTRUCTIVE hurricanes such as Katrina and Rita are likely to be more common … Tim Flannery warns.” “These hurricanes have been a catastrophe just waiting to happen.”
…
The IPCC concludes:
“Studies showed … future tropical cyclones would likely become more severe with greater wind speeds and more intense precipitation.” AR4 10.3.6.3 Tropical Cyclones (Hurricanes) pp786
…
Wow, that’s scary! Let’s look at the studies:
“These studies fall into two categories: those with model grid resolutions that only roughly represent some aspects of individual tropical cyclones, and those with model grids of sufficient resolution to reasonably simulate individual tropical cyclones.”
Oh? That’s models, or er… other models?
But where are the observations?
CO2 levels have risen to the highest level in a million years, presumably Hurricanes, Tornadoes and Cyclones are at all time highs, stronger and nastier than […]
When “experts” say that cyclones and extreme storms will be more common in a warmer world, and are “linked”, “connected”, “expected”, or “definitely” due to man-made CO2 emissions, journalists could try asking some real questions.
…
1. If storms are getting worse thanks to man-made CO2 emissions, why has there been no increase globally as man-made CO2 emissions rose over the last 40 years?
Last 4-decades of Global Tropical Storm and Hurricane frequency — 12-month running sums. The top time series is the number of TCs that reach at least tropical storm strength (maximum lifetime wind speed exceeds 34-knots). The bottom time series is the number of hurricane strength (64-knots+) TCs..

2. So if you admit the global trend doesn’t change, but suggest that the local or regional trends will change, which parts of the world will get fewer cyclones?
If global averages are still “average”, things have to get better somewhere else right?
…
3. So if climate simulations project that Queensland will experience more cyclones, and be […]
Yasi — the super cyclone that isn’t so unusual
Random shot of some coral bits on a beach.
For all the other Christine Milne’s out there, who think coal mining causes cyclones, the empirical evidence inconveniently declares that super-cyclones have been hitting Queensland regularly for the last 5000 years.
As usual, it’s the name-callers who cling to 100 year time-frames and deny the long term evidence, while we “cherry-picking denialists” gravitate towards long term studies based on real observations. (The evidence lies in an obscure industry newsletter called Nature.) The way researcher, Jon Nott, describes it, things have been unusually quiet in our high CO2 world for the last few decades, but cyclones used to be a lot worse, and “worse” is coming back.
Thanks to The Australian for putting together a very timely piece about the historical pattern of cyclone activity.
[Johnathon] Nott is an expert on the incidence of super cyclones. By analysing ridges of broken coral pushed ashore by storm surges, he has catalogued the incidence of super-cyclones over the past 5000 years.
In a paper published in the scientific journal, Nature in 2001 his research shows the frequency of super-cyclones is an order of magnitude […]
Will a hotter world lead to more intense storms?
2010 might be on track to be the warmest ever (according to GISS), but right now, we may be about to set a new record of tropical storms — in inactivity. Ryan Maue tracks the global accumulated activity and reports that by the end of July we might break the record low we set last year.
Ryan N. Maue’s 2010 Global Tropical Cyclone Activity Update
July 15: If no additional ACE occurred in July, the 24-month global ACE total would be 1095 compared to last month at 1173. The previous 30-year low was 1091 set recently in September 2009. No lower values exist during the past 30-years.
Global and Northern Hemsiphere Tropical Cyclone Activity is near a record low
Looking at the National Hurricane Centre, it doesn’t seem like there is much activity on the way between now and the end of July.
Advisories issued for the North Atlantic, The East Pacific, The West Pacific, and the Indian Ocean are all the same:
There is no tropical storm activity for this region.

ADDENDUM BELOW (with answers from Christopher Monckton)
The December SPPI monthly report came out on Jan 23. As usual, it contains graphs of the latest juiciest data: sea levels, ice, sunspots, cyclones, global temperature trends and the latest papers. Here’s a few snippets that caught my eye.
Get ready for 1.4 degrees (or more… or less).
Global Temperature Trends 1981-2009
Call me a cherry picker, but going by the full satellite data record we have and drawing a simplistic straight line, we are rocketing towards 1.4 degrees of warming by 2100, (but only if that trend of the last 30 years doesn’t change, which it is, every year). For those who are new to this, there are two interpretations of the satellite data and this neatly combines both of them (UAH and RSS) and makes one wiggly line out of masses of data. Not surprisingly, the SPPI team have chosen to ignore the surface record of airports and air-conditioners, “ground based thermometers”.
