Now they tell us! Climate warming to weaken wind power in northern hemisphere, increase in Australia: study
After building 341,000 wind turbines, mostly in the Northern Hemisphere, now climate modelers reveal that winds will decrease in the Northern Hemisphere!
Warming temperatures caused by climate change are set to weaken wind energy in the northern hemisphere, a study shows, lessening the amount of wind power produced for wind farms.
However the southern hemisphere would see a boost in wind, which could potentially turn north-eastern Australia into an attractive investment for energy companies.
Rush, invest your money now. The theory called polar amplification has the success rate of a coin toss. Buy a wind farm in NE Australia!
Luckily wind speeds are not also influenced by cloud cover, jet streams, oceans currents, forest growth, atmospheric tides, solar factors, magnetic fields, ozone levels, cosmic rays, or butterflies. Otherwise this study might be inadequate, uninformed guesswork being used to inform investment decisions!

Who cares about 50% more emissions?
China is powered by 65% coal.
A new study in China compares cars with internal combustion engines to electric cars. Qiao et al estimate that from cradle-to-gate electric cars use about 50% more energy and produce around 50% more emissions. (Thanks to Kenneth Richards at NoTricksZone.)
All Greens should hereby recycle their EV and buy a gas guzzler.
This is not even “lifetime costs” which include disposal.
These results will come as no surprise to people who remember the detailed study in Norway of 2012 which found that “…in regions where fossil fuels are the main sources of power, electric cars offer no benefits and may even cause more harm, the report said.”
In China, these electric cars are powered by 65% coal. Call them “coal-fired-cars”.
The largest single difference was with the battery.
Below, marvel at the results of the Chinese study. (ICE means Internal Combustion Engine. BEV means Battery Electric Vehicle.)
Not. Even. Close.
If you think CO2 matters, oil powered cars beat coal powered ones.
ICE = Internal Combustion Engine: BEV = Battery Electric Vehicle. By every measure Electric cars use more energy and emit more CO2.

Matt Ridley writes the letter Theresa May should send to the EU
For 40 years Britain has propped up the EU with nothing in return but complaints and insults.
The fifth biggest economy in the world can offer foreign aid to the failing EU but on the same terms as other needy states.
BRITAIN SHOULD GIVE THE EU £20 BILLION EXTRA AS AN ACT OF CHARITY
Dear Angela, Emmanuel and others (cc Donald, Jean-Claude, Michel),
I enclose a cheque for £40 billion as agreed. However, you will notice that it is post-dated March 30, 2019, and that it will bounce without a free-trade agreement between us, as I mentioned on the telephone. We are delighted to be in a position to be so unilaterally generous, and sorry that you find yourselves in such dire need of our help.
We cannot help feeling that a little more financial discipline on your part might have avoided the need for such a large sum.
For instance, we notice that all Eurocrats can draw generous final-salary pensions when they get to the end of their lucrative careers, throughout which they will have had handsome allowances and […]
A Sunday Mail survey (paywalled) shows that despite SA having more “free, cheap and clean” renewable electricity than just about anywhere in the world, the number one biggest issue for most South Australians is … “electricity”. And despite all the renewable jobs created, the second most common concern is “jobs”. Going for the Paradox-Trifecta: most strangely of all, with elected leaders who are leading the largest energy transformation since civilization began, the third “biggest issue” facing South Australians is “political leadership”.
Thanks to Eric Worrall, who describes South Australians as “the world’s renewable crash test dummies”.
…
SA has an election coming up in March, but at the moment voters there are caught in the bind between the reality of electricity shocks, and the belief that “renewables are cheap”. Will the local Libs (the opposition) have the spine to stand up and speak the truth and make this election about energy and climate, or will they pander #metoo, and lose the unloseable?
Will the Libs get the message here? Most South Australians like the sound of renewables, but when it comes to the crunch, and the issues they will vote on, electricity prices and jobs will rule. This is […]

PMSML stands for Permanent Service for Mean Sea Level, though there is nothing permanent about sea-level data — like all obedient climate change data, it’s subject to change fifty years later — and the adjustments are as large as the trends.
We’ve seen this pattern in so many places. Now Cliff Ollier and Albert Parker have shown it in the Indian Ocean looking at Aden in Yemen, and Mumbai in India (and other places, and other data). Kenneth Richard at No Tricks Zone goes through it at length. James Delingpole calls it TideGate. The New York Times says nothing (just like last time).
Parker and Ollier conclude that at Mumbai, apparently the sea levels were “perfectly stable over the 20th century”. At Aden, sea levels trends are rising at a pitifully small quarter of a millimeter a year during the twentieth century. (And that’s their upper estimate). The lower estimate is minus five hundreths of a millimeter a year. Looking at other sites as well they estimate a rise of …”about zero mm/year” in the last five decades. zero.
This, they say, agrees with other things like… coastal morphology, stratigraphy, radiocarbon dating, archaeological remains, and historical documentation. (But not […]
“Air-conditioning” of The Great Barrier Reef begins soon
To calm a few panicking people, the Australian Government will pay for large fans to circulate water on a minuscule portion of the 2,300 kilometer long Great Barrier Reef. The reef creatures, which have been coping with higher temperatures and bleaching for two hundred million years, will hopefully avoid the moving parts. Marine life adapts to heatwaves by chucking out the symbionts that don’t thrive in higher temperatures and replacing them up new inhabitants that do. If the fans achieve anything, it may stop this natural process (called Symbiont Shuffling) thus possibly making small sections of the reef more vulnerable to future heatwaves and El Ninos. Who knows?
Fans like this are used in the United States to circulate water.
Mark this one up as a pagan symbolic idol that symbolizes our grandiose delusions of weather-control.
Federal Government spending $2.2m on giant ocean fans in bid to protect Great Barrier Reef
Eight huge reef mixer fans are planned for the Great Barrier Reef in far north Queensland, in a trial project that hopes to reduce the damage caused by coral bleaching events.
The Federal Government has […]

The shape of normal AC Electricity: 50Hz (230V) and 60Hz (110V)
Nobody says much about FCAS in public — but it’s become a hot topic among Australia’s energy-nerds and electricity traders. It never used to be a big deal, because we got it at very low cost from huge turbines — from coal, hydro, and gas. Suddenly, it is costing a lot more. As I discovered below, in one month FCAS charges in South Australia rose from $25,000 to $26 million. Wow, just wow.
What is FCAS?
FCAS means”Frequency Control Ancillary Service”. With an AC (or alternating current) system, frequency is everything — the rapid push-pull rhythm that is the power. FCAS is a way of keeping the beat close to the heavenly 50Hz hum (or 60Hz in America and Korea). Network managers cry when things stray outside 49.85Hz or 50.15Hz. So controlling the frequency is a very necessary “other service” supplied by traditional generators, but not so much from intermittent renewables. Large spinning turbines “do” FCAS without a lot of effort. And the cost used to be a tiny fraction of the total electricity bill, but it is rapidly rising in Australia, thanks to the effect of the […]
Climate change causes … more crops.
Climate change threatens our food supply, our grain harvests. It causes wars, droughts, sometimes floods, shorter growing seasons. And we all know Climate change is here. We can see it out the window. Plus 2017 is one of the three hottest years ever.
Somehow all these bad events happened at once and added up to the world’s largest cereal crop ever.
…
It’s doom gloom and fume all the way down:
How a warming world is threatening supplies — The Guardian
Climate Change May Reduce Some U.S. Grain Harvests by Half –– Bloomberg
Wheat, one of the world’s most important crops, is being threatened by climate change —Washington Post Record cereal production leading to record end-season inventories in 2017/18
…
“World wheat inventories are currently pegged at an all-time high despite a downward revision since October. Global stocks of rice and coarse grains are also set to reach record levels. The increase in wheat and rice stocks largely reflects an anticipated accumulation of inventories in China, whereas for coarse grains, the expansion reflects higher end-of-season maize stocks in South America and the United States.” […]
The world is watching one volcano in Bali, but it’s sobering to think there may be hundreds of others going off, and almost certainly ones we don’t even know about. The article Is the Bali volcano making us warmer or cooler? by William F Jasper, reminded me of Ian Plimers words about there being squillions of undersea volcanoes so I found the 2007 paper, by Hillier, that tried to count them. Trying being the appropriate word. Volcanoes are biggish things, but when they are under one or two kilometers of water they are hard to hear, hard to see, and, by crikey, we know more about the moon than the bottom of the Marinara, and it’s only 11km “away”.
People are constantly discovering new volcanoes, like a 3,000m one off Indonesia that no one realized was there til 2010. It turns out the second largest volcano in the solar system is apparently not on Io, but 1,000 miles east of Japan. It’s the size of the British Isles, but who knew? A few months ago a team found 91 new volcanoes under Antarctica. (This is getting serious, someone should talk to the Minister for Lava!)

It was all yellow: A warning was in place for the whole of Victoria.
Massive flooding forecast across “whole state”:
The Bureau of Meteorology has warned an “unprecedented” amount of rain is expected to fall in Victoria over a three-day period.
Asked to rate the storms out of 10, senior forecaster Mr Williams said: “I’ll take the punt and say it’s a 10 for Victoria.”
He said the most recent rain in a short period of time in Melbourne was 100-200 millimetres (in 2005 and 2011) and on both occasions: “it paralysed transport routes in the city.”
Get out your sandbags!
Events were cancelled, and the Premier of Victoria told people not to “have a big night on the town” in preparation.
The city was told to bunker down for an “absolutely massive” rainfall event over the weekend …
“Half the inhabitants of Melbourne have never ever seen anything like this,” the Bureau of Meteorology’s senior forecaster Scott Williams said on Thursday.
“It is an event that poses a threat to life.”
Not so much a flood of rain, but there was a flood of text messages:

The new SA rescue plan is more diesel than battery
Diesel’s prototype engine circa 1892.
A big fuss was made today over the world record battery, but the diesel generators put on a hire-purchase plan three days ago are more than twice the power:
The world’s biggest lithium ion battery has been launched in South Australia, with Premier Jay Weatherill declaring it an example of SA “leading the world”.
The first diesel generator was patented in 1892. Go, Go, SA.
A battery bandaid arrived barely in the nick of time:
That reliability was tested before the battery’s official launch when it began dispatching around 59 megawatts into the state’s electricity network on Thursday afternoon as the state hit temperatures above 30C.
How fragile is this system?
The facility has the capacity to power 30,000 homes for up to an hour in the event of a severe blackout but is more likely to be called into action to even out electricity supplies at less critical times.
There are 673,540 households in South Australia and the Big Battery can supply 4% of them for an hour with electricity, or all of the state for a […]
Grenfell Tower
It takes a lot of effort to set up a situation so dangerous under the guise of “helping the poor and the polar bears”.
Grenfell — Britain’s fire safety crisis
By Gerard Tubb, Sky News Correspondent and Nick Stylianou, Sky News Producer
The UK Dept of Energy and Climate Change wanted help to get insulation onto buildings to save the world in 2011, so it asked the people who sell insulation. Somehow the plastics industry found the energy to turn up and help the government write rules that would increase their sales.
The Grenfell tower, where 71 people died, ended up being coated in Celotex — a flammable plastic. Celotex staff were on that committee, and bragged on their website how they were “working inside government”. It’s another example of a vested interest leaping onto the Carbonista-bandwagon. No conspiracy needed.
Follow the money:
A few years later Celotex revealed that the rules the plastics industry helps to write are key to company profits. Trade magazine Urethanes Technology International reported in 2015 that Warren had told them regulatory change was the “greatest driver” of plastic insulation sales. Without new regulations he was reported as […]
