ENVIRONMENT
'Final Warning To Humanity'

"[T]he world's scientists have spoken, clearly and in one voice," said U.N. Secretary General Ban Ki-moon, on the most recent report of the Nobel Prize-winning Intergovernmental Panel on Climate Change (IPCC). After a rigorous multi-stage review process that includes 2,500 scientific expert reviewers, 800 contributing authors, and 450 lead authors representing 130 countries, the IPCC warns that "all countries" will be affected by climate change if carbon emissions continue to spiral.

By 2100, global average surface temperatures could rise by between 1.1 and 6.4 degrees celsius, and carbon dioxide in the atmosphere could lead to an eventual rise in sea levels of up to 1.40 meters.

With "strikingly" blunt language, the report reads like "a final warning to humanity," notes Time magazine. "What we do in the next two to three years will determine our future. This is the defining moment," declared IPCC chairman Dr. Rajendra Pachauri.

DEBATING WAYS TO BATTLE WARMING: This weekend, Grist and Living on Earth sponsored a presidential candidate forum to discuss ways to tackle climate change, in partnership with the League of Conservation Voters Education Fund, California LCVEF, Center for American Progress Action Fund, Natural Resources Defense Council Action Fund, and the Presidential Forum on Renewable Energy.

The event was attended by Sen. Hillary Clinton (D-NY), former senator John Edwards, and Rep. Dennis Kucinich (D-OH). "[R]educing oil dependence and global warming is the second most important issue among independent voters," states Daniel Weiss of the Center for American Progress.

With "little disagreement among them" on the urgency of climate change, Clinton and Edwards emphasized the need to reduce emissions by 80 percent by 2050, consistent with the goals of the IPCC, along with a mandatory cap on greenhouse emissions. Such plans to combat global warming can be undertaken with a very modest reduction in global annual GDP growth of 0.12 percent, notes Pachauri.

Flipping The Switch On Climate Change

Thanks to an American Senator, the world is being set straight on climate change. Working tirelessly to scuttle former elected President Al Gore's upcoming Capitol Hill celebration as part of a seven-continent “Live Earth” concert tour intended to rally the planet in cheerfully addressing runaway global warming, Oklahoma Republican James Inhofe speaks with the conviction of a Holocaust denier when he calls climate change "The greatest hoax ever perpetrated on the American people!" [The Hill Mar 28/07]

A least since the 2000 and 2004 presidential elections, WMD in Iraq, the Iranian “threat”, the Bush Terror War On Terror, and the constitutional curtain-closing Patriot Acts 1, 2 and 3.

Apparently unafraid of facing future Nuremberg-style environmental trials, Climate Change Deniers as influential as the U.S. National Science Teachers Association have refused 50,000 free DVDs of Gore's Oscar-winning "An Inconvenient Truth" in fear of alienating heavy corporate funders like Exxon and the American Petroleum Institute, which gets scientists fired, publishes expensive ads in newspapers ridiculing melting glaciers, and helpfully provides “teaching aids” such as coal coloring books and classroom videos asserting, “You Can't Be Cool Without Fuel."

That means you, Mr. and Mrs. Penguin.

In sharp contrast, Tony Blair’s government is sending a copy of Gore's global warming documentary to every high school in England, where it will form part of a year-long environmental program in state schools. [Cybercast News Service Feb 9/07]

“I'm confident that the environmental path that I announce will benefit the entire world. It is based on… economic growth.” –GW Bush [NOAA Feb 14/02]

GLACIAL INDIFFERANCE
It’s not easy debating a destabilizing 10,000-foot thick glacier. Despite sea levels and melting polar ice-sheets already at the upper limits of the next 30 year projections… another 500,000 square miles of reflective Arctic sea ice melted into heat-retaining dark water and Alaska’s glaciers decanting more than 13 trillion gallons of meltwater into world ocean circulations each year… and Greenland’s fast-shrinking 2,000 kilometres of solid ice increasing its melting rate over the past five years from a metre a year to a metre a month… and polar bears drowning a hundred miles offshore while looking for ice floes retreating another 300 miles out… and thousands of Canadian harp seal pups experiencing 100% mortality from the same lack of ice… and the first month of 2007 3.4°F hotter than the any January ever recorded… and the snowpack serving drinking water to Seattle and the Pacific Northwest shrinking toward bare rock… and more than a quarter of the American West in either severe or exceptionally severe drought while Arizona cactus wither and die from lack of water—Inhofe and the White House insist, this planet can’t be heating up!

“A polar bear might be able to swim 100 miles. But not 400.” -Nupiak elder Charlie Johnson [CBC Aug 3/04]

“It’s happening much sooner than we thought.” -Ted Scambos, lead scientist U.S. National Snow and Data Center [Guardian Sept 29/05]

“Everyone’s quite shocked at the speed at which these things are changing.” -Bill Wareham, acting director marine conservation, David Suzuki Foundation [AP July 8/05]

"Things are happening a lot faster than anyone predicted. The last 12 months have been alarming." -Bill Chameides chief scientist, Environmental Defense & professor of atmospheric chemistry. [Time Mar 26/06]

On the other hand, an 18-inch rise in sea level will see salt water flowing into the Sacramento River Delta, destroying the drinking water for 23 million Californians. A 20-foot ocean level rise will put half of Florida under water— including Miami, Tampa Bay and Jacksonville—along with the new WTC memorial in Manhattan, and much of Washington DC, where Senator Inhofe is busily blocking climate change-inspired discourse, dancing and music. [Seattle Post-Intelligencer Mar 11/07; BBC July28/04]

In more than 180 countries, one out of every ten people on this planet could soon be chuckling over the climate change hoax while swimming inland. Fortunately for U.S. legislators like Inhofe, only one of these countries is the United States. The rest—China, India, Bangladesh, Vietnam, Indonesia, Japan, Egypt, Thailand and the Philippines have mostly expendable non-white populations who don’t buy much stuff from the United States, which today mostly exports self-deluding fictions, weapons and wars. [Inter Press Service Mar 28/07]

Meanwhile, the rapidly melting and slip-sliding Greenland ice sheet does not know it is a hoax and is set to raise world sea levels 20 to 30 feet, while far to the south, inland Western Antarctic glaciers uncorked by the calving Larson ice shelf are rushing to add another 20-feet or so to the rising sea level hoax. As for the melting Eastern Antarctic… think about relocating to a mountaintop with a dock in your front yard.

Scientists Detail Climate Changes

Poles to Tropics


BRUSSELS, April 6 — From the poles to the tropics, the earth’s climate and ecosystems are already being shaped by the atmospheric buildup of greenhouse gases and face inevitable, possibly profound, alteration, the world’s leading scientific panel on climate change said Friday.

In its most detailed portrait of the effects of climate change driven by human activities, the panel predicted widening droughts in southern Europe and the Middle East, sub-Saharan Africa, the American Southwest and Mexico, and flooding that could imperil low-lying islands and the crowded river deltas of southern Asia. It stressed that many of the regions facing the greatest risks were among the world’s poorest.

And it said that while limits on smokestack and tailpipe emissions could lower the long-term risks, vulnerable regions must adjust promptly to shifting weather patterns, climatic and coastal hazards, and rising seas.

Without such adaptations, it said, a rise of 3 to 5 degrees Fahrenheit over the next century could lead to the inundation of coasts and islands inhabited by hundreds of millions of people. But if steady investments are made in seawalls and other coastal protections, vulnerability could be sharply reduced.

The group, the United NationsIntergovernmental Panel on Climate Change, also noted that the climate shifts would benefit some regions — leading to more rainfall and longer growing seasons in high latitudes, open Arctic seaways and fewer deaths from the cold.

The 1,572-page report, finished here on Friday, was prepared by more than 200 scientists, and a 21-page summary was endorsed by officials from more than 120 countries, including the United States.

'Doomsday' vault design unveiled

By Mark Kinver
Science and nature reporter, BBC News

The final design for a "doomsday" vault that will house seeds from all known varieties of food crops has been unveiled by the Norwegian government.

The Svalbard International Seed Vault will be built into a mountainside on a remote island near the North Pole.
The vault aims to safeguard the world's agriculture from future catastrophes, such as nuclear war, asteroid strikes and climate change.

Construction begins in March, and the seed bank is scheduled to open in 2008.
The Norwegian government is paying the $5m (£2.5m) construction costs of the vault, which will have enough space to house three million seed samples.

The collection and maintenance of the collection is being organised by the Global Crop Diversity Trust, which has responsibility of ensuring the "conservation of crop diversity in perpetuity".

"We want a safety net because we do not want to take too many chances with crop biodiversity," said Cary Fowler, the Trust's executive director.
"Can you imagine an effective, efficient, sustainable response to climate change, water shortages, food security issues without what is going to go in the vault - it is the raw material of agriculture."
