IPCC expected to confirm link between climate change and extreme weather
From the Natural Resources Defense Council (emphasis mine):
“This report should be a wake-up call to those that believe that climate change is some distant issue that might impact someone else. The report documents that extreme weather is happening now and that global warming will bring very dangerous events in the future. From the report you can see that extreme weather will impact everyone in one way or another. This is a window into the future if our political response doesn’t change quickly.”

‘Rogue’ sharks eating people, chasing whales
Experts cite global warming as a potential reason for more interaction with sharks as it may have changed migration habits of both whales and sharks.
And thus, the prefect test for “global warming is a hoax” type people is born…

Scientists and others should be reading this article about some of the issues in communicating about climate change, if you haven’t already.

Geologists Prepare to Drill Into Ancient Antarctic Lake
A team of British researchers are preparing to dig down through three-kilometer-thick ice to sample a lake under the Antarctic in the hope of finding new species and clues about the future impact of climate change.
A team of engineers with 70 tons of gear are to head for Lake Ellsworth in West Antarctica. The lake has been isolated from the outside world for at least 125,000 years — but it could be as many as a million. It’s about 10km long and two to three kilometers wide.
The team’s mission is to prepare the way for the “deep-field” research mission that will take place in October 2012. They will then use hot water to melt through 3,000 meters of ice in order to reach the lake, which remains liquid due to geothermal heat coming from inside the Earth. This technique has been used before in Antarctic experiments, but never this deep. The hot-water drill will need to operate continuously for three days to create a 36cm wide borehole through the ice.
Engineer Andy Tait, from British Antarctic Survey, explains: “The design of the hot water drill is very straightforward — very similar to the hot water you might use on a jet spray to clean a car. The nozzle delivers water at 2,000 psi and 90C, which is needed to melt the ice to create the hole.”
