Jon Stewart Schools Congress On Climate Change With A Simple Demonstration
Over the weekend, some 400,000 Americans took to the streets of New York City to demand action on climate change, but as Jon Stewart pointed out on Monday night's "Daily Show," too many members of Congress continue to deny the science.
Last week, the House Committee on Science, Space and Technology interrogated Presidential Science Advisor John Holdren -- or, as Stewart called him, the hearing's Sisyphus "charged with the impossible task of pushing a million pounds of idiot up a mountain."
Holdren faced questions about "global wobbling," comments from a congressman who refuses to read scientific journals because he doesn't believe them, and gems like this one:
"I mean think about it, if your ice cube melts in your glass it doesn't overflow, it's displacement," Rep. Steve Stockman (R-Texas) said. "This is the thing, some of the things they're talking about, mathematically and scientifically don't make sense."
That got Stewart burning.
"Are you ******* kidding me? Are you ******* kidding me? I don't even know what to do with that," Stewart said. "How far back to the elementary school core curriculum do we have to go to get someone on the House Committee on Science, Space and Technology caught up?"
And with that, Stewart broke out some ice and some water and did an experiment that even a congressman could understand.
Then again, maybe not.

Actually, the reverse is true ( at least in Antarctica) and if you look at recent global maps you'll see how much ice has already melted. Recently, I heard an interesting program about the subject.
CANBERRA (Reuters) - The summer ice melt in parts of Antarctica is at its highest level in 1,000 years, Australian and British researchers reported on Monday, adding new evidence of the impact of global warming on sensitive Antarctic glaciers and ice shelves.
Researchers from the Australian National University and the British Antarctic Survey found data taken from an ice core also shows the summer ice melt has been 10 times more intense over the past 50 years compared with 600 years ago.
"It's definitely evidence that the climate and the environment is changing in this part of Antarctica," lead researcher Nerilie Abram said.
Abram and her team drilled a 364-metre (400-yard) deep ice core on James Ross Island, near the northern tip of the Antarctic Peninsula, to measure historical temperatures and compare them with summer ice melt levels in the area.
They found that, while the temperatures have gradually increased by 1.6 degrees Celsius (2.9 degrees Fahrenheit) over 600 years, the rate of ice melting has been most intense over the past 50 years.
That shows the ice melt can increase dramatically in climate terms once temperatures hit a tipping point.
"Once your climate is at that level where it is starting to go above zero degrees, the amount of melt that will happen is very sensitive to any further increase in temperature you may have," Abram said.
Robert Mulvaney, from the British Antarctic Survey, said the stronger ice melts are likely responsible for faster glacier ice loss and some of the dramatic collapses from the Antarctic ice shelf over the past 50 years.
Their research was published in the Nature Geoscience journal.

Explain why the polar ice caps have more ice now then 10yrs ago. Explain why there has been no real warming in the past 13yrs I believe.
As was the case in the 1970's with the cooling, and the late 80's and early 90's with warming it is a natural earth cycle.
