Ice Bridge Breaks From Antarctica

If you need more evidence of global warming, perhaps you should look at Antarctica, where a bridge holding the Wilkins Ice Shelf to the continent broke away this weekend.
The collapse of the bridge, which was about the size of Jamaica, has scientists worried that the Ice Shelf will soon break away completely. British glaciologist David Vaughan remarked to the BBC on what the bridge’s failure means for the continent as a whole:
We know that [the Wilkins Ice Shelf] has been completely or very stable since the 1930s and then it started to retreat in the late 1990s. But we suspect that it’s been stable for a very much longer period than that.
The fact that it’s retreating and now has lost connection with one of its islands is really a strong indication that the warming on the Antarctic is having an effect on yet another ice shelf.
The bridge’s collapse won’t greatly impact sea levels, but definitely provides a warning of how dire the situation down south has become.

MYTH: Global warming will cause huge disruptions in climate, more storms, and the coasts will flood! America must sign the Kyoto Treaty!
This has to be broken into four pieces.
MYTH No. 1: The Earth is warming!
TRUTH: The Earth is warming. The Intergovernmental Panel on Climate Change (IPCC) said the global average surface temperature increased about 0.6 degrees Celsius over the 20th century.
s has to be broken into four pieces.
MYTH No. 2: The Earth is warming because of us!
TRUTH: Maybe. The frantic media suggest it’s all about us. But the IPCC only said it is likely that we have increased the warming.
Our climate has always undergone changes. Greenland was named Greenland because its coasts used to be very green. It’s presumptuous to think humans’ impact matters so much in comparison to the frightening geologic history of the earth. And who is to say that last year’s temperature is the perfect optimum? Warmer may be better! More people die in cold waves than heat waves.
MYTH No. 3: There will be storms, flooded coasts and huge disruptions in climate!
TRUTH: There are always storms and floods. Will there be much bigger disruptions in climate? Probably not.
Schoolchildren I’ve interviewed were convinced that America is "dying" in a sea of pollution and that "cities will soon be under water!"
Lawyers from the Natural Resources Defense Council (another environmental group with more lawyers than scientists) warn that "sea levels will rise, flooding coastal areas. Heat waves will be more frequent and more intense. Droughts and wildfires will occur more often."
Wow.
But many scientists laugh at the panic.
Dr. John Christy, professor of Atmospheric Science at the University of Alabama at Huntsville said: "I remember as a college student at the first Earth Day being told it was a certainty that by the year 2000, the world would be starving and out of energy. Such doomsday prophecies grabbed headlines, but have proven to be completely false." "Similar pronouncements today about catastrophes due to human-induced climate change," he continued, "sound all too familiar and all too exaggerated to me as someone who actually produces and analyzes climate information."
The media, of course, like the exaggerated claims. Most are based on computer models that purport to predict future climates. But computer models are lousy at predicting climate because water vapor and cloud effects cause changes that computers fail to predict. In the mid-1970s, computer models told us we should prepare for global cooling.
Scientists tell reporters that computer models should "be viewed with great skepticism." Well, why aren’t they?
The fundamentalist doom mongers also ignore scientists who say the effects of global warming may be benign. Harvard astrophysicist Sallie Baliunas said added CO2 in the atmosphere may actually benefit the world because more CO2 helps plants grow. Warmer winters would give farmers a longer harvest season, and might end the droughts in the Sahara Desert.
Why don’t we hear about this part of the global warming argument? "It’s the money!" said Dr. Baliunas. "Twenty-five billion dollars in government funding has been spent since 1990 to research global warming. If scientists and researchers were coming out releasing reports that global warming has little to do with man, and most to do with just how the planet works, there wouldn’t be as much money to study it."
MYTH No. 4: Signing the Kyoto Treaty would stop the warming.
TRUTH: Hardly.
In 1997, the United Nations met in Kyoto, Japan, and asked the developed nations of the world to cut CO2 emission to below 1990 levels.

"sea levels will rise, flooding coastal areas. Heat waves will be more frequent and more intense. Droughts and wildfires will occur more often."
Ah! but dirty laundry makes such good stories. Sometime I think they print stuff like this is because emotional news brings in $$. With everything being printed at different angles of the story it makes it hard to find the truth.
Isnt it also fact that Earth goes through changes every so many 100’s of years? I try not to panic b/c I know media can blow things way up but it does concern me what kind of earth will be here for when my daughter is grown and trying to raise a family…
"Surveyed Scientists agree Global Warming is Real"
excerpt:
"…Two questions were key: Have mean global temperatures risen compared to pre-1800s levels, and has human activity been a significant factor in changing mean global temperatures?
About 90 percent of the scientists agreed with the first question and 82 percent the second.
The strongest consensus on the causes of global warming came from climatologists who are active in climate research, with 97 percent agreeing humans play a role.
Petroleum geologists and meteorologists were among the biggest doubters, with only 47 percent and 64 percent, respectively, believing in human involvement…
However, Doran was not surprised by the near-unanimous agreement by climatologists.
"They’re the ones who study and publish on climate science. So I guess the take-home message is, the more you know about the field of climate science, the more you’re likely to believe in global warming and humankind’s contribution to it.
"The debate on the authenticity of global warming and the role played by human activity is largely nonexistent among those who understand the nuances and scientific basis of long-term climate processes," said Doran. "

Remember the tobacco company execs. with their hands raised in consensus agreement that "tobacco does not cause cancer "
Same story, different day !
