Giant Fans will cool Great Barrier Reef to stop bleaching

 ”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 announced [...]

Electrical appliances force children to marry

Thanks to The Guardian for drawing a link we would never have noticed:

Why climate change is creating a new generation of child brides

As global warming exacerbates drought and floods, farmers’ incomes plunge – and girls as young as 13 are given away to stave off poverty

 If only these girls had perfect weather, they wouldn’t have to be married so young. For a million years of human history, everyone had enough food, there were no wars, no battles, and young women could live at home under they were 25 and had finished up at the Neolithic Academy of Weaving.

Then other people wanted fridges, air conditioners and toasters. Now every time you boil the kettle, a 13 year old girl has to get married in Malawi.

 

Ferrgoodnesssake — the plight of these poor children won’t be fixed by a carbon tax or a windmill.

Your car causes volcanoes (and volcanoes release CO2)

Oh. My. Lord. Keep the car in the garage.

Climate Change Could Increase Volcano Eruptions

Dr Graeme Swindles, from the School of Geography at Leeds, said: “Climate change caused by humans is creating rapid ice melt in volcanically active regions. In Iceland, this has put us on a path to more frequent volcanic eruptions.”

The study examined Icelandic volcanic ash preserved in peat deposits and lake sediments and identified a period of significantly reduced volcanic activity between 5,500 and 4,500 years ago. This period came after a major decrease in global temperature, which caused glacier growth in Iceland.

The findings, published today in the journal Geology, found there was a time lag of roughly 600 years between the climate event and a noticeable decrease in the number of volcanic eruptions. The study suggests that perhaps a similar time lag can be expected following the more recent shift to warmer temperatures.

Climate change will make Bearded Dragons dumber

Young Bearded Dragon worried about falling SAT scores.

Ominously, cute Australian Bearded Dragons (Pogona vitticeps) may grow up to be more stupid if their eggs are incubated in a hotter world.

Bearded Dragons Are Dumber Because of Climate Change

–National Geographic

This has all kinds of implications.

Obviously, it follows that Victorian Bearded Dragons must be smarter than their Queensland cousins. I can see future papers coming on the IQ gradient of dragons down the East Coast of Australia.

Secondly, with this handy simple relationship between IQ and temperature we can infer the entire intellectual history of Bearded Dragons as the climate fluctuated: including the Peak Holocene Dolt Era and the Glacial Genius Maximum.

 

From National Geographic

” The researchers took a single clutch of 13 eggs and split them into two groups. Seven eggs were incubated at a toasty 30°C (86°F), while the other six were incubated at a milder 27°C (81°F). There was an almost even mix of males and females.

Ahh. The cause of lower IQs may be not a hotter world, but a hotter artificial incubator. The message in this paper is Don’t leave artificial incubators lying around [...]

Health Warnings issued for Tasmanians facing six days over 25 degrees (77F +) !

Hobartians face a record heatwave for November

Things are so serious they may find Echidnas in their dog’s water bowl.

Spend billions. Stop climate change. We simply can’t allow this kind of disaster:

Heatwave health alert issued for southern Tasmania as 130yo record set to fall

The weather bureau’s Tim Bolden said it was shaping up to be the first time Hobart has recorded six consecutive days on or above 25 degrees Celsius in November in nearly 130 years.

“[We'll break the record] if we make it to the six days that we’re currently forecasting over 25 degrees — since last Saturday up until Thursday — and it’s certainly looking very likely,” Mr Bolden said.

“[We are] currently forecasting 28 for Tuesday, 29 for Wednesday and 29 for Thursday, having reached 30 last Saturday, 27 on Sunday and 27 on Monday.

“If we make it to that stretch of six days above 25 degrees, that would be a record heat spell for November, and equal to the maximum heat spell for [...]

Climate change will make your Autumns colorless. Darkness is coming.

Put out a press release! Climate change may make color photos turn black and white:

Yale, climate connections: Climate change could dull fall’s spectacular colors

No, but seriously, the situation is so dire that we might not be sure when peak color in fall will occur.

Yingying Xie, a post-doc at the University of Buffalo, says global warming is bringing changes to the region’s fall colors. In general, warmer temperatures cause leaves to turn color later in the season.

But changes in frost and moisture levels, and stresses like drought, heavy rain, and extreme heat can also affect the timing of peak fall color.

Xie: “Climate extremes may bring pretty high uncertainty.”

Peak color may split timing: Color clash coming

If there be droughts, the ash and birch red leaves will occur at a different time to oaks and beeches. Imagine forests with red and green at the same time?

One reason is that different tree species react to climate stresses in different ways. In her research, Xie found that drought caused ash and birch trees to change color earlier than usual. But it made oaks and beeches change color later.

Mysterious thing called Populism affecting wildlife

If only there was no populism:

ScienceDaily.   Researchers at Colorado State University and The Ohio State University have found that a cultural backlash stemming from the rise of populism may limit opportunities for state fish and wildlife agencies to adapt to changing social values in the United States. The team reached this conclusion by analyzing more than 12,000 surveys from 19 states and studying ballot initiatives related to hunting.

Unwind your way through that maze. Academics have spent thousands of dollars to discover that some people have different values to academics. Some people who don’t like new laws are protesting, and that may stop “unlimited” changes. Isn’t that democracy?

In the case of human-wildlife conflict, traditionalists would be more likely to support lethal wildlife control methods while mutualists would be more supportive of restrictions on humans.

After two million years of meat-eating, I’d say homo traditionalist had already been “affecting the wildlife”. Even before the rise of populismisticness.

But if populism is pop-u-lar, what kind of “changing social values” do fish and wildlife agencies really need to adapt to anyway? If the changes are less popular, who says we need to change?

The problem is “Trust [...]

Aussies eating junk to get better weather, old coal plant increases 73,000% in value in two years

Funny things happening today in Australia:

Australians are cutting back on Fruit and Veges to pay electricity bills:

Since eating raw fruit and vege is associated with lower mortality, efforts to stop people dying of climate change in 2100 may be killing people today:

Australians are cutting back on basic things like fresh fruit and vegies in order to keep the lights on with the National Debt Helpline taking 14,000 calls in September — a record for the month, and up 14 per cent on the same time last year.

Dying stranded coal plant increases in value by 73,000% in 2 years:

The NSW government sold Vale Point power for $1m two years ago. It’s now valued at $730m:

In November 2015, the NSW Government offloaded Vales Point Power Station — an old, polluting coal-fired plant on the shores of Lake Macquarie — for $1 million.

Last week,… Sunset Power quietly released its latest financial reports — revaluing the Vales Point Power Plant at a cool $730 million.

Over the past year, Vale Points’ owners gained $380 million from electricity sales from the power station, compared to $270 million for energy generated [...]
