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.

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.

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."

Research team says extraterrestrial impact to blame for Ice Age extinctions


Northern Arizona University
Tue, 25 Sep 2007 14:45 UTC
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.
