During the Permian-Triassic boundary 250 million years ago, the Earth was enjoying some of its warmest temperatures when it was interrupted by a catastrophic cooling event. The new discovery shows an #Ice Age forced a massive die-off of most marine life, and not global warming as once thought. It also shows the role geological events have played on our climate, specifically volcanic eruptions.
While the Earth has gone through a number of #extinction level events, the one that happened at the Permian-Triassic boundary was one of the deadliest. Over 95 percent of marine life vanished from the face of the planet. Scientists previously believed it was from a rise in temperatures that preceded #Climate Change, but researchers from the University of Geneva and University of Zurich discovered the die-off arose from a mini ice age.

Dating the past
The researchers worked on sediment layers found at the Nanpanjiang basin in southern China. Bjorn Baresel, a University of Zurich scientist, said they made several cross sections of the basin sediments to determine the exact positions of ash beds in the marine sediments. Then they dated the sediments using the natural radioactive decay of uranium from the mineral zircon. Because it decays at a specific speed, they can be accurate to within 35,000 years.
Once they dated the various sediment layers, the scientists noticed a mass extinction at the Permian-Triassic boundary represented by a gap in the sediment layers. That gap correlates to a time when seawater level decreased. And sea levels only drop when it gets stored into ice. From there they could determine the ice age lasted about 80,000 years, time enough to kill off 95 percent of all marine life.
Scientists have long believed a mass die-off was caused by global warming. A new study shows differently.During the Permian-Triassic boundary 250 million years ago, the …
Flashback 1974: Global Cooling Caused Droughts, Floods, Blizzards, Tornadoes, Typhoons, Hurricanes & Polar Vortex!
In 1974, everything which is currently blamed on global warming, was blamed on the longest global cooling trend on record: 0.5C cooling since 1945.
These was problematic for NASA’s fake climate science, so they simply rewrote the past to eliminate the cooling.

Winter is Coming: The Long-Run Effects of Climate Change on Conflict, 1400-1900
We investigate the long-run effects of cooling on conflict. We construct a geo-referenced and digitized database of conflicts in Europe, North Africa, and the Near East from 1400-1900, which we merge with historical temperature data. We show that cooling is associated with increased conflict. When we allow the effects of cooling over a fifty-year period to depend on the extent of cooling during the preceding period, the effect of cooling on conflict is larger in locations that experienced earlier cooling. We interpret this as evidence that the adverse effects of climate change intensify with its duration.

For decades, global warming scaremongers have been stealing energy from the environment using windmills, solar collectors, and biofuels, force-fed by carbon taxes and emission trading schemes. Their delusional dream is to cool the globe.
However, there has been no global warming for nearly 20 years. Right now, the great ice sheets are growing thicker, and record snow is blanketing much of the climate change leader, the Northern Hemisphere landmass. Solar panels are blinded by snow, and turbines don’t turn in the cold still air, or else they have to be shut down because of icing or high winds. Like all green things, wind and solar power often hibernate in winter.
Meanwhile, the unloved all-weather energy producers (coal, gas, and nuclear) are straining at their limits, as families huddle around heaters fearing the first flickers of failure from overloaded power grids.
No food is produced from land smothered in snow – farmers fear late frosts and welcome early spring rains and warmth.
For the last million years, Earth has experienced long cycles of ice separated by short warm inter-glacials. Today’s warm era is already a mature twelve thousand years old, and Earth’s climate is fluctuating naturally toward the next glacial cycle in which many animals and plants will perish. Only fools would assist the return of the ice.
Warmists are making a massive mistake by assuming that global cooling is better than global warming. They are ignoring their precious “Precautionary Principle.”
A frigid ice house is far more dangerous and destructive than a warm greenhouse.

KUSA – It’s a snow report that would inevitably make any powder hound salivate: 20 inches in the last 20 hours, 28 inches in the last 48 and 68 inches in the last week.
It’s a lot of snow – so much snow, in fact, that Monarch Mountain is the second ski resort in two days to say it can’t open due to too much of that white powder.
“Monarch Pass is closed all night for avalanche control, preventing Monarch Mountain maintenance, food service and grooming crews from reaching the mountain,” the resort wrote on Facebook Tuesday. “Stay tuned for information on status and conditions for tomorrow, Jan. 11.”
Photos shared on Monarch’s Facebook page show heavy drifts of snow at the resort.
Monarch Mountain joins Crested Butte in having a very, very unique problem.
Crested Butte announced Monday that it would have to close its lifts due to safety concerns arising from too much snow. On Tuesday, they tweeted they were working on getting everything back open.
Some impressive winter events have been taking place all across the northern hemisphere lately. Especially eastern and southeastern Europe have been pounded by massive snowfalls and tremendously cold temperatures. Turkey has been buried by heavy snows and extreme temperatures have gripped the entire USA and vast areas of Russia.
The global warming climate appears to have been hacked by natural factors.
- In Russia Moscow celebrated the coldest orthodox Christmas in 125 years.
- Snowfall paralyzed the city of Istanbul, Turkey.
- Massive snow falls across the Balkans, Italy and Greece.
- Dozens of Europeans have since frozen to death.
- Northern Albania villages have been cut off by 120 cm of snow.
- A temperature of -62°C (-80°F) was recorded in Chanty-Mansijsk (Russia).
Arctic conditions spread deep into the Mediterranean
These are all odd events when considering the “consensus” forecasts made 15 years ago, which warned that snow and ice would become rare.
In fact many scientists warned that Mediterranean conditions would spread into northern Europe. Lately, however, just the opposite has happened: Arctic conditions have plunged down into the Mediterranean!
Even worse, there is no end in site for the harsh European winter conditions, German mass circulation daily Bild writes here.
Warning of an impending ice age
So in the face of all the earlier global warming predictions, it is now only ironic that yesterday the German-language Pravda TV site here published an article warning of an impending ice age. The article cites Yale scientist Wei Liu and a recent paper he published on the “overlooked possibility of a collapsed Atlantic Meridional Overturning Circulation“. Should the ocean heat conveyor collapse, then there would be “a prominent cooling over the northern North Atlantic and neighboring areas, sea ice increases over the Greenland-Iceland-Norwegian seas and to the south of Greenland.”
The Pravda report summarizes Liu’s paper as follows:
CO2 has nothing to do with it, rather the influence of the sun is the dominant factor: less sunspots (Climate: solar physicists project global cooling (video)), weakening of the earth’s magnetic field, impact on the jet stream are decisive factors

The Hottest Year on Record? A lot of hot air, more like
UK Telegraph’s Booker’s on form today:
Inevitably, as 2016 neared its end, the usual suspects, such as the BBC, were all piling in to remind us that it was “the hottest year on record”, with particular focus on the recent “super-heatwave” producing temperatures 20 degrees or more above average in the Arctic. But as usual it has been important to know just what all this fevered hype was leaving out.
The reason I so often quote the blog run by Paul Homewood, Notalotofpeopleknowthat, is that, uniquely on this side of the Atlantic and drawing on a huge range of scientific and historical data, he so expertly explains what we are not being told by the prevailing fog of propagandist groupthink emanating from governments and the media on all matters relating to climate and energy.

Who might have guessed, for instance, how the closing weeks of “the hottest year evah” have seen unusual cold and snowfall across a vast swathe of the northern hemisphere: snow in the Sahara desert, Saudi Arabia, Syria, the Peloponnese, Korea, China. Blizzards across the northern United States from Montana to New England. Even in Siberia, not a stranger to extreme cold, locals have been stunned by temperatures as low as minus 60 degrees. A graph based on official data shows that snow extent in the northern hemisphere last autumn was the second greatest on record since 1967, and that five of the snowiest have come since 2010.
As for that “Arctic heatwave”, in a post headed “Going to the Arctic? Don’t bother packing that bikini”, Homewood shows a chart giving detailed temperature readings on Christmas Day for that entire region. Although in a small sliver around the North Pole temperatures were much higher than usual, thanks to warm air blowing in from the south, for much of the Arctic temperatures of minus 30 and 40 degrees were as usual for this time of year.
Homewood shows that similar warm spikes have regularly occurred before, not just in recent years but way back through the 20th century. According to the satellite records shown on Crysophere Today, last summer’s annual ice-melt was in fact less than that in seven of the previous nine years.
Of course even the most light-headed warmists concede …
Sowell’s first column ever, titled “The Profits of Doom,” was written decades before the global warming hysteria among today’s environmentalists. During the 1970s, scientists were warning of a coming ice age.
“The first column I ever wrote, 39 years ago, was titled ‘The Profits of Doom,’” Sowell wrote in his final column, according to The National Review.
“This was long before Al Gore made millions of dollars promoting global-warming hysteria,” Sowell wrote. “Back in 1970, the prevailing hysteria was the threat of a new ice age — promoted by some of the same environmentalists who are promoting global-warming hysteria today.”
First Week of 2017: Record Cold, 48 States Going Below Freezing
December 28th, 2016 by Roy W. Spencer, Ph. D.
It is increasingly looking like the first full week of 2017 will be greeted with a cold air outbreak over the Lower 48 states that will be widespread and persistent.
Early next week the cold air will enter the U.S. through Montana and the Dakotas, where temperatures will likely plunge into the minus 30 deg F (or colder) range.
By the end of the week, single digits could extend into the southeast U.S., and a hard freeze could push into central Florida (graphic courtesy of Weatherbell.com):
As can be seen, substantial portions of all 48 states might well be below 32 deg. F.
At the longer range, there appears to be a reinforcing plunge of even more frigid air heading south out of northwest Canada in the second week of January.
