The ‘2010 State of the Climate’ Report: 
Indicators show a “clear and unmistakable signal” that our world continues to warm, making extreme weather events more likely
From The Washington Post:

The world’s climate is not only continuing to warm, it’s adding heat-trapping greenhouse gases even faster than in the past, researchers said Tuesday.
Indeed, the global temperature has been warmer than the 20th century average every month for more than 25 years, they said at a teleconference.
“The indicators show unequivocally that the world continues to warm,” Thomas R. Karl, director of the National Climatic Data Center, said in releasing the annual State of the Climate report for 2010.
“There is a clear and unmistakable signal from the top of the atmosphere to the depths of the oceans,” added Peter Thorne of the Cooperative Institute for Climate and Satellites, North Carolina State University.
Carbon dioxide increased by 2.60 parts per million in the atmosphere in 2010, which is more than the average annual increase seen from 1980-2010, Karl added. Carbon dioxide is the major greenhouse gas accumulating in the air that atmospheric scientists blame for warming the climate.
The warmer conditions are consistent with events such as heat waves and extreme rainfall, Karl said at a teleconference. However, it is more difficult to make a direct connection with things like tornado outbreaks, he said.
“Any single weather event is driven by a number of factors, from local conditions to global climate patterns and trends. Climate change is one of these,” he said. “It is very likely that large-scale changes in climate, such as increased moisture in the atmosphere and warming temperatures, have influenced — and will continue to influence — many different types of extreme events, such as heavy rainfall, flooding, heat waves and droughts.
The report, being published by the American Meteorological Society, lists 2010 as tied with 2005 for the warmest year on record, according to studies by the National Oceanic and Atmospheric Administration and NASA. A separate analysis, done in Britain, lists 2010 as second warmest.

The Pacific Institute for Climate Solutions has hosted an impressive line-up of climate change researchers over the last two years, but tonight they are hosting a biggie:

Speaker: Dr. Naomi Oreskes, Professor of History and Science Studies, University of California San Diego, author and 2011 Climate Change Communicator of the Year

Title: Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Global Warming

Description:  Find out why people mistakenly believe the science of climate change is unsettled. In Merchants of Doubt, Oreskes and co-author Erik Conway revealed how a group of high-level scientists, with extensive political connections, ran effective campaigns to mislead the public and deny well-established scientific knowledge over issues including acid rain, the ozone hole, global warming, DDT, and the harms of tobacco.

This long campaign of sowing doubt, which found its roots in the ideology of free market fundamentalism, has skewed public understanding of some of the most pressing issues of our era.

Time & Location: Mon. June 27, 7:30 - 9:00 pm | Flury Hall (B150), Bob Wright Centre, University of Victoria

You can watch a live webcast of Oreskes’ lecture starting at 7:30pm Pacific time.

The devastating string of tornadoes, droughts, wildfires and floods that hit the United States this spring marks 2011 as one of the most extreme years on record, according to a new federal analysis.

Just shy of the halfway mark, 2011 has seen eight $1-billion-plus disasters, with total damages from wild weather at more than $32 billion, according to the National Oceanic and Atmospheric Administration. Agency officials said that total could grow significantly, since they expect this year’s North Atlantic hurricane season, which began June 1, will be an active one.

Overall, NOAA experts said extreme weather events have grown more frequent in the United States since 1980. Part of that shift is due to climate change, said Tom Karl, director of the agency’s National Climatic Data Center.

"Extremes of precipitation are generally increasing because the planet is actually warming and more water is evaporating from the oceans,” he said. “This extra water vapor in the atmosphere then enables rain and snow events to become more extensive and intense than they might otherwise be.”

But for some kinds of extreme weather, teasing out a contribution from climate change is more difficult.

The second half of April brought a swarm of tornadoes that leveled parts of the Midwest, including the twister that killed 151 people in Joplin, Mo. So far, 2011 has seen the sixth-highest number of tornado deaths on record, prompting many people to wonder whether climate change has played a role. So far, scientists say there’s no good evidence for or against a climate change influence on tornado behavior.

Meanwhile, computer models predict that droughts — like those that have scorched large swaths of Texas, New Mexico and Arizona this year — will become stronger and more frequent as climate change continues. But because patterns of drought vary widely from decade to decade, that makes it “very difficult and unlikely that we’re going to be able to discern a human fingerprint, if there is one, on the drought record in the foreseeable future,” Karl said.

A Climate Science Hip Hop Video… starring Climate Scientists!

In what may be a first, here’s a hilarious and NSFW climate science themed hip hop video featuring real climate scientists. The video and song were produced for an Australian TV show that combines ”journalism, comedy and the reportage of weird.” You can read the lyrics on the show’s website, but in the mean time here’s a salty, one verse sample:

Feedback is like climate change on crack 

The permafrosts subtracts: feedback 

Methane release wack : feedback 

Write a letter then burn it: feedback 

Denialists deny this in your dreams 

Coz climate change means greater extremes, 

Shit won’t be the norm 

Heatwaves bigger badder storms 

The Green house effect is just a theory sucker (Alan Jones) 

Yeah so is gravity float away muther f**cker 

Boo ya!

When:                 7:30 pm – 9 pm PDT | Thursday, April 7, 2011

Where:                Flury Hall, Bob Wright Centre, University of Victoria

Description:

The battle of truth versus disinformation is nowhere better demonstrated than in the distortion of climate science. More than 97 percent of practicing climate scientists support the fact that global warming is happening and caused by humans, yet the public often thinks that scientists are seriously divided on this issue.

In this special public lecture, Silicon Valley computer scientist and technology expert Dr. John Mashey will expose the underhanded, but effective PR/lobbying tactics of the anti-science campaign. It has included Internet-propagated disinformation, personal attacks, threats of violence and hate mail, including the manufactured non-event “Climategate.” His talk will examine the organization and activities of anti-science funders, think tanks, and spokespeople over the last 20 years, including recent developments and initiatives to counter their efforts.
