Life on Earth mostly made it through 500 million years of asteroids and supervolcanoes only to be wiped out by a half a degree temperature rise. This really will be unprecedented.
Climate change could destroy half of Earth’s animal and plant species in the next 50 years, disturbing study says
Despite animals surviving temperature rises of 20 degrees every day, a half a degree of warming in 50 years will kill off half the species on Earth.
A disturbing new study suggests that climate change could wipe out half of the planet’s animal and plant species by 2070.
The research notes that if temperatures rise 0.5 degrees Celsius around the globe, approximately half of the world’s species would become locally extinct. If temperatures were to rise 2.9 degrees Celsius, 95 percent of the species would become locally extinct.
Note the scale on the graph of the last 500 million years. I marked half a degree in the red box.

I’m not too concerned about life on Earth surviving the next 50 years. But at this rate of decay, science is cactus.

Skeptics mention the Urban Heat Island and its crickets from the ABC.
A green group mentions the Urban Heat Island effect and the ABC is happy to advertise:
Australian cities are increasingly becoming concrete jungles as trees and canopy coverage disappear, according to experts who warn this is contributing to an urban “heat island” effect.
“We know a tried and tested strategy is the introduction of more trees and green roofs in urban spaces, reducing surface temperatures by up to 40 per cent,” Griffith University urban and environmental planner Tony Matthews said.
40% of what, we might wonder, but the ABC doesn’t.
Could this huge heat effect possibly affect temperature records creating a systematic century scale bias inflating and creating fake hottest ever records. Nothing to see here, nevermind.
What radiates like an oven but doesn’t heat thermometers?
A national initiative — called Greener Spaces Better Places — brings together academic, government and industry groups to promote further greenery in our cities. Its research says black bitumen and dark roofs compound the already-hot days by creating a so-called heat island effect, absorbing heat and radiating it back like an oven.
Radiating like an […]
Pick a number, any number — the message is always the same. In 2018 the IPCC dropped the arbitrary 2C target to an arbitrary 1.5C target. The world hadn’t warmed fast enough, and worse, the new round of CMIP6 models were pushing their estimates of climate sensitivity up. But regardless, there are PR points to be made in every change. It’s an excuse for another round of “worse than we thought” press releases.
Commenter Joe teased:
Have the IPCC now become deniers? looks like we can only expect only .5 degrees C warming over the coming decades….

You’ve lost sight of the pea.
All the wild predictions are based on “Post Industrial” there has been about 0.95 deg since then, plus 0.5C brings us to the magic 1.5.
What you have to see is that all the $billions is about “preventing” an imperceptible and completely harmless 0.5 deg C change in temperature that might just come naturally anyway.
You are being duped. The aim frankly is to create an income stream via treaty that requires sovereign countries to levy […]
Here in Renewables-World downunder, most people don’t know the grid has barely scraped through the last two weeks. We almost lost an Aluminium smelter, came close to a statewide blackout and South Australia is (possibly) still islanded from the rest of the National Grid.
The AEMO held a crisis meeting yesterday but this trouble started Friday week ago in what was described as a “white knuckle event” by energy analyst, Paul McArdle at WattClarity. A storm knocked down six large transmission towers on the high voltage interconnector line in Western Victoria which left South Australia suddenly islanded. This time SA had 1,000MW more energy than it could use, so frequency in SA suddenly rose to a near disastrous 50.96Hz and briefly perhaps even higher. (Wait for the official reports). The system teetered but managed to stay running. Prices rocketed up to the usual spike to $14,500/MWh in both Victoria and South Australia.
It would have been nerve-wracking in the control rooms. The Portland Aluminium Smelter in Victoria, which is the largest single user of electricity in Victoria, had a near death experience. Both pot lines shut down immediately. It appears emergency workers only managed to get 50% of the […]

Looks like the dams will still fill. Sydney’s main dam — the Waragamba was only 42% full a few days ago, now it’s 70% full, and most of the fires are out, or will be soon. 16 river systems have flooded, and 13,000 people are being evacuated. Where is that hotter-drier future when you need it?
Sydney rains: Record rainfall brings flooding but puts out mega-blaze
Sydney has been hit by its heaviest rain in 30 years, bringing widespread flooding but also putting out two massive bushfires in New South Wales. Australia’s weather agency said 391.6mm of rain had fallen in the past four days in Sydney, more than three times the average rainfall for February. About 100,000 homes are without power, and officials have warned flash floods could be life-threatening.

The Australian Bureau of Meteorology predicted average rain just five weeks ago
Jan 2nd 2020: “February to April has roughly equal chances of being wetter or drier than average for most of Australia.
While outlooks for drier than average […]
So much for the “hotter drier” future they were warning us about 3 weeks ago
As predicted, droughts in Australia often end in floods. It is the way it has always been. Today people are already being rescued from the rising water and possibly another 200 -300mm of rain may fall before Sunday warns the BOM. Many fires have been extinguished.
Climate change has made no difference to the drought trends in Australia in the last 178 years and climate models are totally skilless at rainfall. When will the climate modelers admit that these are natural cycles?
‘We’re only half way through’: East coast smashed by flashflooding and heavy winds
Forecasters become increasingly concerned that even more rain could fall even faster than expected as five people have been rescued from floods.
The NSW State Emergency Service issued a flood warning for Sydney’s metropolitan areas, saying forecast weather conditions were “likely to cause widespread flooding”.
Flooding has already occurred in Roseville in Sydney’s Upper North Shore and the north-western suburb of Putney, where commuters are advised to allow extra travel time.
Meteorologists have said they are increasingly worried about the unfolding weather events […]
A fateful decision that led to many deaths
The Samoan Islands, 1896 | Wikimedia
Western Samoa and American Samoa are side by side islands in the Pacific. When the Spanish Flu arrived in 1918, one would instigate a quarantine while the other had a trading community that did not want to stop trade. American Samoa survived the Spanish Flu without a death. Western Samoa kept trading and lost a quarter of the population.
Influenza 1918: the Samoan experience
John Ryan McLane
In 1918 the Samoan archipelago was split between American Samoa (a United States territory) and Western Samoa (previously a German colony but under New Zealand governance from 1914). The 1918 influenza pandemic killed a quarter of Western Samoans, while leaving American Samoa unscathed.
The dangers of ship-borne disease were well known, and exclusion of many diseases, especially plague, had been implemented since the imposition of colonial governance nineteen years before.
On 30 October 1918 the Union Steamship Company’s Talune left Auckland for its run through Polynesia… The new, more lethal influenza variant had arrived in Auckland with the spring, and several crew members were ill.
Western Samoa was a German colony that […]
Donald Trump’s State of the Union is being described as one of the best ever. It was a magnificent campaign speech. Even the LA Times calls it “a pretty effective one”. I don’t watch many political speeches, but this one could be a “how to” guide.
The dour faced white suits of the #Metoo look decidedly unAmerican and self centred when Trump announces great results for all their token mascots and they can’t even clap. Nancy Pelosi petulantly rips up the speech that Trump had to provide her with at 1:42:50. Some news services are trimming that bit off…
Trump shamelessly plugs his heroes and basks in their greatness. Rush Limbaugh gets a Presidential Medal of Honor. Buzz Aldrin singled out early at the start. (6:30)
“This year American Astronauts will go back to Space on American Rockets.”
John Hindraker:
This puts the Democrats in a tough spot. Through the first half of the speech, President Trump reeled off one item of good news after another: Record low unemployment! Lowest black unemployment ever! Lowest Hispanic unemployment ever! Rising wages, especially at the bottom! Median net worth skyrocketing! And so on. The Democrats greeted all […]
Divestment Snowflakes protesting at St Johns College Jan 30th
Students at St Johns College were protesting last week at the fossil fuel investments that help keep the College running. Even camping out in the quadrangle in the middle of winter:
“We are not going anywhere” – St John’s locked down over Climate Strike
The Oxford Student
Oxford students have occupied St. John’s College since Wednesday, demanding that the College divests its £8.1 million of disclosed investments in fossil fuel companies and all undisclosed fossil fuel investments from its £551 million endowments.
Dozens of students have set up camp in the front quad of St. John’s equipped with banners and placards, to demand that it takes the climate emergency seriously and measures to remove the social licence of fossil fuel companies.
As of Thursday afternoon, there are allegations that St. John’s College had disabled student’s room keys. Instead, they are allegedly doing manual Bod card checks, escorting students to and from their rooms, and are not allowing non-residents to enter the college. There are reports of students bringing protesters food as they have remained on the quad since yesterday.

From the other side of the world comes this extraordinary collection of data that few in Australia seem aware of.
File this fact away: Satellite datasets show that in an average year 50 million hectares burns around Australia. In a quiet year, it’s only 20 million hectares, but in a busy year it gets close to 100 million hectares. A lot of this land area is in the far north and western part of the continent, which is hot and often arid. It’s not the same as the cool wet corner of South East Australia which has some of the tallest trees in the world. The fuel loads in the north are much lower (like the trees).
Some parts of the top end burn nearly 100%, year after year. It’s no accident that the awful devastation this year was not in the red hot firezone on the map below, but in the South East corner where less than 5% of the area burns each year. The rarely burnt is the risky zone where there is a 20 year build up of fuel. Some areas are on a 1 in 100 year rotation or even slower. There were places this year […]
The WHO could have declared a state of emergency earlier. Instead it delayed the announcement, praised China’s transparency, and recommended countries allow planes potentially carrying a deadly virus continue to fly freely. The WHO waited until the 2019-nCoV virus had spread to 18 nations before declaring an emergency. Wasn’t it an emergency with the first foreign case or the first case of symptomless transmission?
Follow the chain, or rather the Belt and Road
The WHO Director General is Tedros Adhanom of Ethiopia. From 2012 – 2016 he served as Minister of Foreign Affairs in the one party government that rules Ethiopia. This is the same party that borrowed billions from China to build a railway line, then struggles to pay it back. In Africa, Ethiopia is the second largest debtor nation to China — owing $13 billion. As Foreign Minister Adhanom praised China for African loans, looks like he was the man to line them up. We also note that the one-party ruling party of Ethiopia is called the Tigrayan People’s Liberation Front which was once a Marxist Lenninist far left group — labels it dropped after the Soviet Union collapsed. (Thanks Maurice for these tips).

Been trying to do a Corona thread for three days, but every time it was half finished everything changed.
The WHO have finally declared a state of emergency, something that seemed inevitable as soon as we knew the virus could be transmitted by people without symptoms. Russia, Mongolia, and North Korea closed their borders Thursday. Hong Kong announced a temporary closure. Singapore has now closed its borders too. Mark Steyn meanwhile, marvels that healthy US citizens are being advised not to go to China, but it’s apparently fine for sick people to travel the other way. Extraordinarily a cruise ship with 6,000 passengers was “stuck” off Italy, waiting for clearance for two Chinese people who had symptoms like a flu. Fortunately they must have just had the flu. The ship was cleared. And so it is around the world with a mosaic pattern of super actions, versus business as usual.
British Airways has suspended all flights to and from China, as have many other airlines, but in a city by city way. The virus is now present in every region of China. It’s not clear why all flights to and from China have not been stopped. On ABC news Australia’s […]

Populism is becoming very popular
The Chairperson bureaucrat sums the petty pointlessness of the EU so well. As the Brits triumphantly and disobediently wave their flags, she tries to order them into submission: “Could we please remove the flags. ” “If you disobey the rules you get cut off” — she threatens to cut off the nation that’s celebrating that it has cut itself off.
Freed from the self-serving undemocratic conglomerate meddlers. Brilliant, and best wishes to the UK.
At long last, they’ll be able to buy whatever dang hairdryer they want…

If only they had overwhelming evidence they could post YouTubes that were popular
As Steve Milloy says “Not only are we winning the debate… we are forcing our opponents to show who the actual would-be-dictators are. “
Here’s Dem Kathy Castor writing to the YouTube CEO to ask him to stop YouTube suggesting skeptical videos as “up next” or earning advertising money.
To Sundar Pichai,
CEO, Google, CA
[snip intro]
As we all work together to solve this crisis [climate change], we must also eliminate barriers to action, including those as pervasive and harmful as climate denial and climate misinformation.
That’s why I urge you to ensure that Youtube is not incentivising video’s by removing them immediately from the platform’s recommended algorithm; Add ‘climate misinformation’ to the platforms list of borderline content; Stop monetizing videos that promote harmful misinformation and falsehoods about the causes and effects of the climate crisis; Take steps to correct the record for millions of users who have been exposed to climate misinformation on YouTube.
Please respond by Friday February 7, to describe any efforts you plan to take in order to address these important issues.

ABC writers see only the cruel obstacles in the way of a wealth transfer:
Solar generation is being buffeted by financial headwinds that are killing investment
Who knew that the whole point of financial winds is to kill off dumb investments in the first place? Not the socialist ABC.
If the ABC weren’t an advertising agency for Big Gov dependents, the headline could have read:
Artificial solar bubble busts in Australia: green investors burnt

Ten times the fuel means 100 times the intensity
Hardly anyone is talking about these numbers yet they show just how far beyond our control the pyroconvective firestorms are and why we need to be so much smarter at preventing them. They also show how irrelevant temperatures onsite are, compared to fuel load and wind speed.
Controllable fires are 3MW per meter, but we now have loads of 70MW/m
Not only are these fires obscenely, catastrophically intense, it doesn’t matter how much fire fighting equipment we buy, how many dams we empty, they are a man-made disaster, and we’ve known for years how to prevent them. (Some would say, thousands of years). The message in here is that cool controllable burns are tiny, less damaging, and far less intense. The pyroconvective monsters are totally different creatures.
Andrew Bolt interviewed fire expert David Packham in November:
Top fire expert David Packham says forget global warming. It’s the reckless failure to burn-off fuel loads that have turned parts of Australia into death traps. Near Melbourne “we’re looking down the barrel in these areas at 1000 deaths”.
His key point is that if we increase the fuel by ten, […]
Angela Merkel, last week. Source: Kremlin
Now she gets it — fifty years after school:
DAVOS, Switzerland (Reuters) – The world needs an open dialogue about climate change to heal the gap between sceptics and believers since time is running out to cut the emissions that drive global warming, German Chancellor Angela Merkel said on Thursday.
This may seem important after three decades of skeptics being called deniers, and being shut out of every debate, decision and research grant. But it has all the hallmarks of relevance-deprivation-syndrome. The US people elected a skeptic, and he and Saint Greta have stolen her limelight:
The first two days of the annual Davos gathering were dominated by the back-and-forth between the 73-year-old former businessman Trump and 17-year-old campaigner Greta Thunberg, with corporate leaders caught in the middle, concerned that as well as words, there was a need for concrete decisions.
Statements like this provide cover for the reality which is rampant social ostracism, exclusion, coercion and bullying. But it’s soothing theatre for the Davos crowd who would love to be seen to be diplomatic. They are clapping their own generous image.
She drew applause from the […]
It’s an arson epidemic
Holy Smoke Batman! An astonishing 12,000 fires have started in New South Wales since August. The police have investigated 1700 so far. Of those, fully 42% are described as “deliberately lit” which includes both intentional and accidental and at the moment police refuse to put a number on how many are truly arson, as opposed to people deliberately lighting a campfire which ran amok. Only 156 fires of the total investigated, or 9%, were caused naturally (presumably that means by lightning).
Another 745 fires of the 1700 are not yet determined. There seems plenty of scope to increase the number of man-made fires but I would assume the extent of lightning strikes are already known.
‘Like nothing we’ve ever seen before’: police step up bushfire investigations
Forty specialist police officers will investigate to zero in on and profile would-be arsonists. “Strike Force Tronto is about profiling. It’s about zeroing in on serial arsonist behaviours that occurs during the bushfire period,” he said.
“That sets the framework for the next fire season so that we do zero in on and target those individuals who we believe may be involved in arsonist behaviour. “This […]
In the largest city in a country with 300 years of coal left, yesterday the government asked a few million people to pull down the blinds on a midsummers day, to turn off the pool pumps, and not run the dishwasher from 4 – 8pm if they could avoid it. It was 42 degrees C.
Remember the good old days when the nation could afford to run the air con? Here in metropolis Australia, some days it’s better to bunker down in a few dark rooms with the air con at survival mode.
Welcome to Renewable World. What’s wrong with all those solar panels? Between dust storms and bushfires and the hail in Canberra, possibly they are covered in dust or soot, or perhaps, holes.
Imagine how much productive brain power is being consumed. The whole nation (almost) is becoming involved in management of the hypercomplex random generation network. As well as all those poles and wires and control rooms, we now need radio and twitter to send messages to the serfs to open and close windows, change their work schedules, or run out and click the pool pump off.
