If man made CO2 emissions have any effect at all on extinctions — it stops them happening
New research looked at 500 years worth of extinctions and concludes that species loss peaked about a century ago. Far from the rate accelerating as we pour carbon dioxide into the sky, fewer species are disappearing now than forty or fifty years ago.
Kristen Saban and John Wiens considered data on as many as two million species. They specifically analyzed some 912 plants and animals that became extinct in the last 500 years.
Many of the doom and gloom forecasts took extinction rates from long ago and extrapolated them mindlessly forward, as climate modelers are want to do.
Extinction rates have slowed across many plant and animal groups, study shows
EurekaAlert
“To our surprise, past extinctions are weak and unreliable predictors of the current risk that any given group of animals or plants is facing,” said lead author Saban, who recently graduated from the U of A and is currently a doctoral student at Harvard University.
Humans have wiped out species, but mostly by bringing in rats, pigs and goats to isolated islands:

Rich nations protect the Earth
Despite the UN blaming the rich nations for destroying the planet, the data shows that wealthy nations have cleaner air and water and less deforestation.
A team at Yale compile a score called the Environmental Performance Indicator. It tracks 58 factors like biodiversity, species protection, particulates in air, pollution in water, forest integrity and fish stocks. It also, sadly, considers “climate change mitigation” measures — which no doubt adds some pointless noise to the line. But the underlying trend is clear. The only countries in the highest ranks of Environmental Performance are the ones with a GDP per capita higher than $30,000 US.
Possibly the best thing we could do for the environment is help poor nations grow their own economy. And the stupidest thing we could do is push unreliable energy onto the third world and deprive them of coal plants “for the sake of the environment”.

Obviously, anyone can raze a forest, and throw rubbish in the river, but it costs money to protect trees and plants, clean up waste, and filter factory chimneys. People who are hungry understandably, don’t care much about setting up […]

The prophesy of the Sixth Mass extinction has popped up again with hyperbolic modelling to scare us out of our money and just in time for a UN convention. As Steve Milloy says it’s just a giant land and power grab by the UN, which has just finished another meeting for “Biodiversity” — it’s the Baby-IPCC for biology. It was co-hosted by Canada and China. They couldn’t even be bothered thinking up a new acronym so it was called COP15. Rinse, repeat, and press go for spin.
Journalists can cut-n’-paste the formula and adjectives from the IPCC climate press releases: blah etc blah, …close to 200 countries reached “a watershed agreement to stem the loss of nature worldwide” (but not the US). Somehow the “bleary eyed delegates” (who arrived in jets), have waved their magic wands and cast a spell to save the Earth. The solution, apparently, is for the rest of us not to use about a third of our own country, or something like that. The UN bureaucrats can decide what use is OK, and punish us with threats of “endangered listings” if we don’t spend enough on their […]

Kap København is almost the closest point there is to the North Pole on dry land.
The survival of some DNA for two million years is astounding all of itself — breaking the record for oldest known DNA by nearly a million years. Before this, the oldest DNA was thought to be 1.2 million years — beyond which all the global DNA of all the species that ever lived was assumed to be dissolved into unreadable mush.
But now we have found enough of the ancient code to identify a whole ecosystem on the northern edge of Greenland that no one expected to find. Apparently giant elephant-like Mastodons were wandering the far northern parts of Greenland — practically as close as they could get to the North pole without swimming.
At the time, the world was not just 1.5 catastrophic degrees warmer than today, but a full nuclear 10 to 17 degrees hotter.
Strangely life on Earth wasn’t suffering the sixth mass extinction.

Since Europeans arrived Koalas have been booming and busting
The calls were out this week saying that koalas will be extinct in New South Wales in 30 years. But they didn’t mention that Koalas thrive and multiply so fast that in the right conditions scientists talk of ‘plagues’. On Kangaroo Island last year, there were so many koalas, the South Australian government has been trying to sterilize or relocate thousands of them over the last twenty years. Periodically scientists even discuss whether we have to cull them (the horror!).
They’ve survived twenty megafires in 200 years. They can recover. Ponder that Koalas were only introduced to Kangaroo Island in the 1930’s but by the 1990’s there were 14,000 of them and even though they are considered a tourism asset they are also considered a problem and pest too.

Two different models predict two totally different futures. On the left, catastrophic extinction. On the right, happy bats. Click to enlarge
Yesterday a UN supercommittee of 145 scientists from 50 countries declared that one million species are set for extinction. The same day, ten other scientists published a paper pointing out that most modelers forget to allow for genetic variation and thus overestimate the extinction rate. (It’s like they’re modelling the World of Clones – take one small study, pretend they’re all the same — extrapolate globally.) Have a look at the big difference in model outcomes in figure 1 (right).
As I keep saying, 500 million years of brutal climate change means almost every species carries around an industrial tool-kit of handy genetic tricks. Matz et al estimated corals already have the genes to survived another 250 years of projected IPCC catastrophe (in the unlikely event that it happens). Liew et al showed corals even have epigenetic tricks as well as genetics ones. Another group showed when corals are heated something like 74 different genes are activated — often genes that we don’t even know what they’re there for.

A baby-IPCC of biology has just been born
The new 145-expert-committee has just uttered its first words, and the headlines are Hollywood-apocalyptic: A million species face extinction. Daddy-UN is proud.
Nature is in its worst shape in human history, UN report says
Nature is in more trouble now than at any other time in human history, with extinction looming over one million species of plants and animals, scientists said Monday in the UN’s first comprehensive report on biodiversity.
Naturally, these are estimates from unverified models that count species we haven’t even discovered yet. This is truly a scare-based-on-air, except air is real and has weight, and this isn’t that substantial.
Dr. Patrick Moore, co-founder of Greenpeace, explains how vaporous this really is:
“Since species extinction became a broad social concern, coinciding with the extinction of the passenger pigeon, we have done a pretty good job of preventing species extinctions.”
Moore bluntly mocked species extinction claims made by biologist Edward O. Wilson from Harvard University. Wilson estimated that up to 50,000 species go extinct every year based on computer models of the number of potential but as yet undiscovered species in […]
Where’s the apocalypse: With all the forecasts of doom, is this it?
Global Lament is rising for the small brown rat (Melomys rubicola) lost off a desert island no one heard of til morning tea today. This is a rat that was only recognised as a distinct species in 1995, though even then, it was debated, and the rat’s existence was hanging by a thread. The island is a 5 hectare sand spit with a bit of low scrub and an old rusty scaffold once called a lighthouse. So it’s all of 0.05 square kilometers: it is so small there is no fresh water on the island, just the odd puddle after it rains. It’s all so ephemeral that over a decade or so the island shrank 40% and the vegetation was wiped out by 97% (details below). Life on shifting sands in the Torres Strait is all pathetically desperate. It’s 200km off Queensland but only 50km from Papua New Guinea and the highest point (if you could call it that) is 3m about the high tide mark. In other words, any decent wave could have washed the last one off. It’s sad, but it’s not “climate change”.

After half a billion million years of climate change, I’m shocked, shocked I tell you, that life on Earth (and specifically corals) have so many ways to cope with the climate changing. After all, it’s natural (if you are trained by Greenpeace) to assume that corals can only survive in a world with one constant stable temperature just like they never had.
One more tool in the coral-reef-workshop
Corals don’t just have a tool-box, they have a Home Depot Warehouse. h/t to GWPF
We already knew corals chuck out the symbionts that don’t work so well and pick up better partners. Plus, evolution left a stack of genes lying around that were honed in a world that was warmer, and natural selection has a way of amplifying better combinations as conditions shift. Then there is the way corals can be reseeded from safe sites, far away. Now we find out that corals can use epigenetics too.
Epigenetics is that kind of spooky effect where people can inherit the exact same DNA code yet it works or doesn’t work depending on whether it was Dad’s copy, or Mum’s, or whether parents were starved, fearful or stressed. It’s weird, see […]

A new paper finds that there is already enough genetic variety spread across the Great Barrier Reef to adapt to the imagined “unprecedented” warming coming in the next two centuries. We don’t need to rely on random mutations or consider fantasy solutions of man-made oceanic sunscreens, mass sunshades, or giant reef fans. Corals already have a major immigration program running pretty effectively to juggle 200 million years of genetic material and then spread the successes far and wide. Meddling humans can help things (maybe) by moving a few bits of coral around. That’s it. Cancel the scare please.
Skeptics have been saying this for years — who needs a computer model to predict that the Barrier Reef will adapt? How bad could global warming be? The global oceans span a 32C range and corals prefer the hottest five degrees of that. Indeed, there is a five degree temperature range from one end of the Great Barrier Reef to the other, and corals are clearly, obviously pretty happy about it. Meanwhile, the atmosphere is warming at a mere tenth of a degree per decade. Then there is the well known phenomenon that corals spawn in vast clouds that are […]
In 1964 an earthquake made some parts of the Pacific into ponds on a few islands. Fifty years later and the fish in those ponds are now freshwater fish. Apparently the genes for dealing with that sort of wild extreme change are held by some of the fish in the crowd and natural selection can work its wonders in a decade.
In terms of ocean acidification, this is as catastrophic as it gets, not only did the ocean become “more acidic” but it stopped being an ocean.
It can’t get much worse than this for a fish, and yet somehow life on Earth had the answer.
What’s the pH of those ponds — The ocean pH is 8.1, rain is 5.5. Those ponds will be somewhere in between.
And some people think a man-made “ocean acidication” that’s smaller than this and slower, will devastate the ocean.

Evolution is usually thought of as occurring over long time periods, but it also can happen quickly. Consider a tiny fish whose transformation after the 1964 Alaskan earthquake was uncovered by University of Oregon scientists and their University of Alaska collaborators.
