Forget global warming: Welcome to the new Ice Age

Snow cover over North America and much of Siberia, Mongolia and China is greater than at any time since 1966.

The U.S. National Climatic Data Center (NCDC) reported that many American cities and towns suffered record cold temperatures in January and early February. According to the NCDC, the average temperature in January "was -0.3 F cooler than the 1901-2000 (20th century) average."

Russian scientist says Earth could soon face new Ice Age

Temperatures on Earth have stabilized in the past decade, and the planet should brace itself for a new Ice Age rather than global warming, a Russian scientist said in an interview with RIA Novosti Tuesday.

Research team says extraterrestrial impact to blame for Ice Age extinctions

What caused the extinction of mammoths and the decline of Stone Age people about 13,000 years ago remains hotly debated. Overhunting by Paleoindians, climate change and disease lead the list of probable causes. But an idea once considered a little out there is now hitting closer to home.

A team of international researchers, including two Northern Arizona University geologists, reports evidence that a comet or low-density object barreling toward Earth exploded in the upper atmosphere and triggered a devastating swath of destruction that wiped out most of the large animals, their habitat and humans of that period.

Carbon dioxide did not end the last Ice Age

Deep-sea temperatures rose 1,300 years before atmospheric CO2, ruling out the greenhouse gas as driver of meltdown, says study in Science.

Extraterrestrial impact wiped out life during Ice Age

Extraterrestrial impact possibly wiped out all life forms on Earth during the Ice Age, a new study by a team of international researchers, including two Northern Arizona University geologists, has revealed.

What caused the extinction of mammoths and the decline of Stone Age people about 13,000 years ago remains hotly debated. Overhunting by Paleoindians, climate change and disease lead the list of probable causes.

The 'Old' Consensus? (NASA predicted human caused ice age in 1971)

Climate Change: Did NASA scientist James Hansen, the global warming alarmist in chief, once believe we were headed for . . . an ice age? An old Washington Post story indicates he did.

On July 9, 1971, the Post published a story headlined "U.S. Scientist Sees New Ice Age Coming." It told of a prediction by NASA and Columbia University scientist S.I. Rasool. The culprit: man's use of fossil fuels.

Wobbles of Mars Produced 40 Ice Ages

Wobbles in the rotation of Mars swung the planet into about 40 extreme ice ages in the past 5 million years and allowed thick ice layers to remain far away from the poles, an astronomer says.

Various spacecraft have revealed evidence for ice ages on Mars. Around 4 million to 5 million years ago, precipitation events sent piles of snow and ice that accumulated around the ice caps. Nowadays, the only visible ice on Mars is the pair of polar caps. But in recent years, orbiting probes have found solid evidence for vast sheets of underground ice near the red planet's equator, at what scientists call mid-latitudes.

Wolf

Ice Age extinction claimed highly carnivorous Alaskan wolves

The extinction of many large mammals at the end of the Ice Age may have packed an even bigger punch than scientists have realized. To the list of victims such as woolly mammoths and saber-toothed cats, a Smithsonian-led team of scientists has added one more: a highly carnivorous form of wolf that lived in Alaska, north of the ice sheets.

Wolves were generally thought to have survived the end-Pleistocene extinction relatively unscathed. But this previously unrecognized type of wolf appears to have vanished without a trace some 12,000 years ago.

The study, which will be published in the June 21 online issue of Current Biology, combined genetic and chemical analyses with more conventional paleontological study of the morphology, or form, of the fossilized skeletal remains. This multifaceted approach allowed the researchers to trace the ancient wolves' genetic relationships with modern-day wolves, as well as understand their role in the ancient ecosystem.

"Being able to say all of those things - having a complete picture - is really unusual," said lead author Jennifer Leonard, a research associate with the Smithsonian Genetics Program, and currently at Uppsala University in Sweden.

Forget warming - beware the new ice age

In the 1970s, leading scientists claimed that the world was threatened by an era of global cooling.

Based on what we've learned this decade, says George Kukla, those scientists - and he was among them -- had it right. The world is about to enter another Ice Age.

The Younger Dryas Impact Event and the Cycles of Cosmic Catastrophes - Climate Scientists Awakening



The eagle screams,
And with pale beak tears corpses. . . .
Mountains dash together,
Heroes go the way to Hel,
And heaven is rent in twain. . . .
All men abandon their homesteads
When the warder of Midgard
In wrath slays the serpent.
The sun grows dark,
The earth sinks into the sea,
The bright stars
From heaven vanish;
Fire rages,
Heat blazes,
And high flames play
'Gainst heaven itself"

R.B. Anderson, "Norse Mythology," 1875

NASA seems to spend a lot of time looking for and thinking of ways to divert errant asteroids that might possibly hit earth. However, they keep reassuring the public that the probability of actually being hit by an asteroid is extremely small. So why all the attention?
