BEIJING, Dec. 12 (Xinhuanet) -- A recent climate study using computer models indicates that if greenhouse gases continue to be released at their current rate, most of the Arctic basin will be ice free in September by 2040.
And winter ice, now about 12 feet thick, will be less than 3 feet thick.

NARRATOR (JACK FORTUNE): This is a film that demands action. It reveals that we may have grossly underestimated the speed at which our climate is changing. At its heart is a deadly new phenomenon. One that until very recently scientists refused to believe even existed. But it may already have led to the starvation of millions. Tonight Horizon examines for the first time the power of what scientists are calling Global Dimming.

MANILA - Typhoon Utor swept out of the Philippines killing four people, including three children, and stranding thousands on Monday after high winds and waves tore up power lines and communication links in the archipelago.
Utor, currently a category 1 typhoon with gusts of around 140 kph (93 mph), was forecast to weaken to a tropical storm by Friday on a path that peters out south of the Chinese island of Hainan by the weekend, according to www.tropicalstormrisk.com.
The National Disaster Coordinating Council (NDCC) said three children were confirmed dead, including a one-year-old girl whose house was struck by a falling tree in central Capiz province. Four were listed as missing.

A blast wave swept across the face of the Sun on Wednesday, rippling outward from the site of a large solar flare. Blast waves that spread all the way across the Sun like this one did are rare, especially when the Sun is in the quiet phase of its 11-year cycle, as it is right now.
The wave was imaged by the Optical Solar Patrol Network telescope at the National Solar Observatory (NSO) in Sunspot, New Mexico, US. Watch a video of the expanding blast wave. The wave compresses and heats the solar plasma as it passes, causing it to brighten.
The wave raced outwards from the site of the flare at 400 kilometres per second, says K S Balasubramaniam of NSO. It occurred near one edge of the Sun's face and traveled to the other edge in about 30 minutes, he says.

Los Angeles -- Global warming from 55 million years ago suggests that climates are highly sensitive to carbon dioxide, according to a study published by the latest issue of Science.
Scientific studies show that a massive release of carbon into the atmosphere caused the ancient global warming event known as the Paleocene-Eocene Thermal Maximum (PETM) that began about 55 million years ago.
The resulting greenhouse effect heated the earth as a whole by about 9 Fahrenheit (5 Celsius) in less than 10,000 years, geologic records show.
The increase in temperatures lasted about 170,000 years, altering the world rainfall patterns, making the oceans acidic, affecting plant and animal life and spawning the rise of our modern primate ancestors, according to the study by Mark Pagani, associate professor of geology and geophysics at Yale University.

Beijing-- For scientists at this ice-encircled outpost, global warming is not a matter of debate. It is a simple fact and crucial research questions centre on what its consequences will be.
Antarctica is a prime place for this research because it serves as an early warning system for climate change and is a major influence on global weather.
As about 90 per cent of the world's ice volume and 70 per cent of its fresh water is on the southernmost continent, any substantial warming could cause a rise in sea levels around the globe.
"It's a bellwether for the planet," Tom Wagner of the US National Science Foundation said in an e-mail interview. "Its ice sheets are the main player in sea level rise; there is already evidence that they are shrinking."

Mankind has had less effect on global warming than previously supposed, a United Nations report on climate change will claim next year.
The UN Intergovernmental Panel on Climate Change says there can be little doubt that humans are responsible for warming the planet, but the organisation has reduced its overall estimate of this effect by 25 per cent.

HONOLULU (AP) _ The U-S Senate has cut 19 (m) million dollars in proposed earthquake assistance for Hawaii.
That has left the state scrambling to find other sources of federal money to assist agricultural water systems on the Big Island that are still recovering from the October 15th earthquakes.
