Sorry to ruin the fun, but an ice age cometh

THE scariest photo I have seen on the internet is www.spaceweather.com, where you will find a real-time image of the sun from the Solar and Heliospheric Observatory, located in deep space at the equilibrium point between solar and terrestrial gravity.

What is scary about the picture is that there is only one tiny sunspot.

Comment: Chapman has it only partly right. He excludes the evidence for cometary dust loading that contributed to the last ice age (and most likely previous ones). The increased depositional flux evidenced from Gabrielli's paper shows that it was not the sun alone that caused the last ice age:

And from Victor Clube's talk:
You first take the modern sky accessible to science, especially during the Space Age, and you look at its' darker debris with a view to relating its behavior to the more accessible human history which we can, in principle, really understand. And by this approach you discover from the dynamics of the material in space which I'm talking about that a huge comet must have settled in a Taurid orbit some 20,000 years ago, whose dense meteor stream for 10,000 years almost certainly produced the last Ice Age.
Now the question must be asked, Is there a relationship between the sun's missing spots and a 100,000 year ice age cycle coupled with cometary debris entering the solar system?

Whatever happened to our ice age?

Today scientists are warning of a warming planet - but didn't they claim a new ice age was on the way just 40 years ago? SARAH LEWIS gets in a time machine and takes a look at the science of the 1970s.

In the 1970s, scientists predicted an ice age.

Nearly 40 years later, there is worldwide alarm as we are repeatedly warned of catastrophic warming to our climate.

US: Skeleton of a Giant Sloth from Great Ice Age Found in Carlsbad (CA)

The skeleton of a giant ground sloth has been found buried deep beneath an old ranch in northern Carlsbad, it was reported Monday.

The skeleton was found late last month beneath Robertson Ranch and is the second fossil of an ancient mammal to be discovered by construction crews digging in the area, The San Diego Union-Tribune reported.

Snakeless in Ireland: Blame Ice Age, Not St. Patrick

During St. Patrick's Day next week, most revelers won't remember the patron saint of Ireland for his role as a snake killer.

But legend holds that the Christian missionary rid the slithering reptiles from Ireland's shores as he converted its peoples from paganism during the fifth century A.D.

St. Patrick supposedly chased the snakes into the sea after they began attacking him during a 40-day fast he undertook on top of a hill.

An unlikely tale, perhaps - yet Ireland is unusual for its absence of native snakes.

It's one of only a handful of places worldwide - including New Zealand, Iceland, Greenland, and Antarctica - where Indiana Jones and other snake-averse humans can visit without fear.

This grass snake swimming in duckweed belongs to one of only three snake species native to Britain.

After the last ice age about 10,000 years ago, swollen seas prevented snakes from migrating throughout parts of northern Europe - and none made it to Ireland.

Even still, the legend that St. Patrick banished snakes from the Emerald Isle in the fifth century A.D. lives on in popular culture.

Solar Activity Diminishes; Researchers Predict Another Ice Age

Global Cooling comes back in a big way

Dr. Kenneth Tapping is worried about the sun. Solar activity comes in regular cycles, but the latest one is refusing to start. Sunspots have all but vanished, and activity is suspiciously quiet. The last time this happened was 400 years ago -- and it signaled a solar event known as a "Maunder Minimum," along with the start of what we now call the "Little Ice Age."

Tapping, a solar researcher and project director for Canada's National Research Council, says it may be happening again. Overseeing a giant radio telescope he calls a "stethoscope for the sun," Tapping says, if the pattern doesn't change quickly, the earth is in for some very chilly weather.

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.
