Default Scientists: global warming is real

Scientists: global warming is real
Friday, February 18, 2005 Posted: 0547 GMT (1347 HKT)

WASHINGTON (Reuters) -- Studies looking at the oceans and melting Arctic ice leave no room for doubt that it is getting warmer, people are to blame, and the weather is going to suffer, climate experts have said.

New computer models that look at ocean temperatures instead of the atmosphere show the clearest signal yet that global warming is well underway, Tim Barnett of the Scripps Institution of Oceanography said.

Speaking at an annual meeting of the American Association for the Advancement of Science, Barnett said climate models based on air temperatures are weak because most of the evidence for global warming is not even there.

"The real place to look is in the ocean," Barnett told a news conference.

His team used millions of temperature readings made by the U.S. National Oceanic and Atmospheric Administration to calculate steady ocean warming.

"The debate over whether or not there is a global warming signal is now over, at least for rational people," he said.

The report was published one day after the United Nations Kyoto Protocol took effect, a 141-nation environmental pact the United States government has spurned for several reasons, including stated doubts about whether global warming is occurring and is caused by people.

Barnett urged U.S. officials to reconsider.

"Could a climate system simply do this on its own? The answer is clearly no," Barnett said.

His team used U.S. government models of solar warming and volcanic warming, just to see if they could account for the measurements they made. "Not a chance," he said.

And the effects will be felt far and wide. "Anywhere that the major water source is fed by snow ... or glacial melt," he said.

"The debate is what are we going to do about it."

Other researchers found clear effects on climate and animals.

Ruth Curry of the Woods Hole Oceanographic Institution found that melting ice was changing the water cycle, which in turn affects ocean currents and, ultimately, climate.

"As the Earth warms, its water cycle is changing, being pushed out of kilter," she said.

"Ice is in decline everywhere on the planet."

A circulation system called the Ocean Conveyer Belt is in danger of shutting down, she said.

The last time that happened, northern Europe suffered extremely cold winters.

She said the changes were already causing droughts in the U.S. west.

Greenland's ice cap, which contains enough ice to raise sea levels globally by 23 feet (7 meters), is starting to melt and could collapse suddenly, Curry said.

Already freshwater is percolating down, lubricating the base and making it more unstable.

Sharon Smith of the University of Miami found melting Arctic ice was taking with it algae that formed an important base of the food supply for a range of animals.

And the disappearing ice shelves meant big animals such as walruses, polar bears and seals were losing their homes.

"In 1997 there was a mass die-off of a bird called the short-tailed shearwater in the Bering Sea," Smith told the news conference.

The birds, which migrate from Australia, starved to death for several years running when warmer waters caused a plankton called a coccolithophore to bloom in huge numbers, turning the water an opaque turquoise color.

"The short-tailed shearwater couldn't see its prey," Smith said.
Unfortunately it is too late to reverse the effects, maybe it we had listened to the earlier warning and acted sooner we could have saved lives.

Every life has a price to be saved.
Lifes will be saved at a price.
People who can pay will pay.
Now is the time to hone the technologies that might help to save life in a near future and get prepared to cash in.

There is no arguing or debating on that.

In the other post regarding global warming many people were quick to deny it as a real occurrence and thought that scientist had some secret political agenda.

The data, measurements of glacial ice receding and satellite radar images of ice disappearing in the poles are all indicators that something is happening. Yet the media and particularly our pro energy, anti-enviroment government are ignoring this and treating it as a hoax.

At what point will they recognize and admit this is a real threat even for them and how will they explain themselves for being obstructionist and a big contributor to this problem.

There are a lot of people who will not concern themselves with the environment until/unless our impact on it changes it to a degree where it affects their day to day lives. For most, I believe, financial success and security are more tangible than potential environmental damage.

On a side note, I think that a good way to identify blind partisan cheerleaders is to find regular joes who argue big business's position on the issue. No one but a big business executive, a politician in his pocket, or a big business patsy would possibly argue the merits of ignoring environmental science.

The insurance industry woke up a while ago. Swiss re and Munich re (the 2 largest reinsurers in the world) recognize the existence of global warming and that that man made emissions could be a major factor. Both believe it will lead to an increase in "catasrophic" weather related events.

Entities like these, as well as NASA, cannot be written off as wacko scientists with no idea what they are talking about.

How true, I guess if you have dwelled in a city for most of your life and have never actually seen much of the environment or how crops are grown, then yes maybe it is some abstract scientific theory that has no effect on your Wall Street lively hood.

How many people in these big cities such as New York for example realize that if all shipping into the cities ceased for four days they would be facing massive starvation.

That's a cheap shot.

Your example that "if all shipping into the cities ceased for four days they would be facing massive starvation" is the kind that makes people shake their heads.

I could just as easily say that those who make a living on Wall Street would be among the first to see the effects of global warming to the extent it would contribute to a rise in sea levels. They are the kind of folks who can afford ocean front property.

You're not going to get anywhere on the issue if you start by essentially insulting the intelligence of people who live in major cities. Particularly since the major cities are where a large portion of votes for a political candidate that would be willing to take action will come from.

City Joins Suit Against 5 Power Companies

By JULIA PRESTON and ANDREW C. REVKIN

"New York City officials, evoking an apocalyptic vision of Manhattan's tunnels flooded and Kennedy Airport under water, joined a federal suit brought yesterday by New York and seven other states against five of the country's largest power companies in an effort to curb global warming.

New York was the only city to join the suit, which was brought by states dissatisfied with the Bush administration's policies on controlling emissions of carbon dioxide, a greenhouse gas that has been linked to the significant warming of the earth in recent decades.

Painting a scenario that could have come from "The Day After Tomorrow," the city's top lawyer, Michael A. Cardozo, detailed the "extraordinary impact" he said global warming could one day have on New York. It could bring a sharp increases in asthma cases, he said, as well as erosion of beaches in Queens and the Bronx and flooding of Staten Island wetlands.

"And it can mean, to put this most dramatically, flooding of the Holland and Lincoln Tunnels and on the landing strips at La Guardia and Kennedy Airports," Mr. Cardozo said.

While city officials did not suggest that any of those calamities were imminent, they accepted Attorney General Eliot Spitzer's view that the scientific evidence was "rock solid" that carbon dioxide concentrations contributed to global warming."



Mayor Michael R. Bloomberg decided to participate in the suit - a clear challenge to President Bush's approach to pollution control - because he believes that the city should not delay action on the issue, Mr. Cardozo said.

Not to mention that Wall St. itself would be under water if the oceans rose 23 feet.

One can build dams. Democratic wall street has money enough to pay.
