Fire Earth

Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Canceling Your Life Insurance Policy with Nature

Posted by feww on April 15, 2008

WILD FACTS SERIES

Ice and Snow

Humans are in a great hurry to cancel their life insurance policy with nature, melting the snow and ice. As a result of climate change, mountain snow and glaciers are melting earlier, in the spring instead of summer, resulting in water scarcity during the hotter summer months when the precious water is most needed.

“This is just a time bomb,” said hydrologist Wouter Buytaert at a meeting of geoscientists in Vienna.

Areas most at risk from water shortages include the United States, South America, Australia, the Middle East, southern Africa, and the Mediterranean.

The most vulnerable places are earth’s sub-tropic zones, where 70 percent of the world’s population live. Report

Ice caps influence the weather

Just because water in an ice cap or glacier is not moving does not mean that it does not have a direct effect on other aspects of the water cycle and the weather. Ice is very white, and since white reflects sunlight (and thus, heat), large ice fields can determine weather patterns. Air temperatures can be higher a mile above ice caps than at the surface, and wind patterns, which affect weather systems, can be dramatic around ice-covered landscapes.

Some glacier and ice cap facts

Picture of Stephens Glacier, Alaska.

  • Glacial ice covers 10-11 percent of all land.
  • According to the National Snow and Ice Data Center (NSIDC), if all glaciers melted today the seas would rise about 230 feet (70 meters).
  • During the last ice age (when glaciers covered more land area than today) the sea level was about 400 feet (122 meters) lower than it is today. At that time, glaciers covered almost one-third of the land.
  • During the last warm spell, 125,000 years ago, the seas were about 18 feet (5.5 meters) higher than they are today. About three million years ago the seas could have been up to 165 feet (50.3 meters) higher.
  • Largest surface area of any glacier in the contiguous United States: Emmons Glacier, Washington (4.3 square miles or 11 square kilometers)

ice caps and global water distribution

Charts showing that 1.7 percent of Earth's water is ice and 68.7 percent of freshwater on Earth is ice. Even though the amount of water locked up in glaciers and ice caps is a small percentage of all water on (and in) the Earth, it represents a large percentage of the world’s total freshwater. As these charts and the data table show, the amount of water locked up in ice and snow is only about 1.7 percent of all water on Earth, but the majority of total freshwater on Earth, about 68.7 percent, is held in ice caps and glaciers.

One estimate of global water distribution
Water source Water volume, in cubic miles Water volume, in cubic kilometers Percent of total water Percent of total freshwater
Ice caps, Glaciers, & Permanent snow 5,773,000 24,064,000 1.7% 68.7%
Total global freshwater 8,404,000 35,030,000 2.5%
Total global water 332,500,000 1,386,000,000

Travel Warning

Posted by feww on April 15, 2008

Muggings are on the rise. Avoid Traveling to New Zealand.

After the latest incident in which eight English and dutch tourists, including two women, were attacked by a large gang of knife-wielding Caucasian New Zealanders, and other incidents of robbery targeting foreign visitors (see references below), a trend seems to be emerging.

The attackers, 6 men in their late 20s or early 30s, shouted, “they have the wrong accent!” as they proceeded to stab six of the tourists, in what seems to be a mugging incident.

If you are traveling to New Zealand

  • Don’t drive on the deadly roads.

  • Don’t walk alone. Make sure you visit places in groups of 20 to 30 people.

  • When attacked by muggers, hand over your money without any resistance, or you could get stabbed.

Another Racist Murder?

Posted by feww on April 15, 2008

Why do foreigners have the annoying habit of getting themselves killed in New Zealand?

The man whose body was found in the Waikato River is identified by New Zealand police.

He was 17-year-old Tianye LU, a Chinese national.

As expected, New Zealand police said, “there were no suspicious circumstances linked to Mr Lu’s death.” Report

Does it matter to the Chinese Government that its citizens are being killed [‘found dead’] in new Zealand rivers and on NZ roads, or do they have more important business to take care of?
