Lewis Black on global warming

A guest essay from climate scientist James Hansen

The following is an essay distributed by email to a number of friends and journalists by pioneering climate scientist James Hansen. It is a response to controversy generated by his testimony before Iowa’s utility board, in which he likened coal trains to “boxcars headed to crematoria.” —– Emails received regarding the letter from the National […]

Heat waves take a toll on Australian fruit bats

Climate change has, ahem, taken a swing at bats. Unable to deal with scorching heat waves, thousands of Australian fruit bats have flapped their wings, panted, drooled — then dropped dead. Which begs the question: Do bat researchers spend a lot of time yelling, “Quick — to the bat cave!” We really, really hope so.

Necessity is the mother of invention … and some really bad ideas

Mein Gott. I was so hoping that this article was from The Onion or something. Porta-nukes will power oil-shale melters, because there's just no topping the American spirit -- the willingness to take a truly abysmal idea (oil shales) and make it worse:

Per-person gas consumption has decreased in the last year

On the heels of the year's biggest travel week, some interesting news:

Consumers purchased an average 9.32 million barrels of gasoline a day in the week ended Nov. 23, down 1.7 percent from the same week last year ... It was the fifth consecutive week that demand at the pump dropped compared with a year earlier.

The price [of gas] was 38 percent higher than a year earlier.

That's right, population rose, but gas consumption fell, year-over-year. Measured per person, that's a decline of about 3 percent -- not huge, but still noteworthy.

So does this mean that higher prices are starting to take a bite out of our appetite for fuel? That a slowing economy is making consumers tighten their belts? Either way, as long as it isn't a temporary blip in the data, it's a trend worth paying attention to.

What folks are saying about the upcoming Bali talks

Representatives from nearly 200 nations will gather in Bali, Indonesia, next week to discuss what’s to be done about this whole climate-change thing once the Kyoto Protocol expires in 2012. So what’s the word on the street? United Nations Secretary General Ban Ki-moon has been clear about his expectations: “The world’s scientists have spoken, clearly […]

2007 likely to be sixth warmest year on record, say researchers

The year 2007 is likely to tie with 2006 as the sixth warmest year on record, say British researchers who provide data to the World Meteorological Association. The researchers had predicted a year ago that 2007 might be the hottest evah, but it’s instead likely to come in behind 1998, 2005, 2003, 2002, and 2004. […]

GAO says the electric sector’s got a big subsidy to match

The GAO has reported on subsidies to our electric sector, proving what Grist readers already (sadly) know, namely that subsidies to the dirty folks vastly exceed existing or proposed subsidies to cleaner generation.

The most remarkable thing is that the biggest subsidies, like nuclear liability guarantees and lower debt costs through rate payer guarantees, aren't even included in the list (although, to the GAO's credit, it does acknowledge their existence).

So who's packing the biggest, er, subsidy?

CO2 levels hit new record in 2006

The World Meteorological Organization (WMO), in its new 2006 Greenhouse Gas Bulletin, reports:

In 2006, globally averaged concentrations of carbon dioxide (CO2) in the atmosphere reached their highest levels ever recorded ... 381.2 parts per million (ppm), up 0.53 per cent from 379.2 ppm in 2005.

Note this is a one-year rise of 2.0 ppm, continuing the accelerated trend of the past decade, which is due to increases in global economic activity and carbon intensity, together with decreased efficiency of natural sinks, like the ocean.

Must-see ice-sheet TV

Do you want the latest data -- some not yet published -- and the best post-IPCC scientific predictions on the stunning collapse of Arctic ice and unexpected shrinking of the Greenland (and Antarctic) ice sheets? Then you should definitely watch this C-SPAN video of yesterday's American Meteorological Society seminar (see note on link below).

The seminar is by three of the world's top cryosphere experts: Dr. Mark Serreze (NOAA), Scott Luthcke (NASA), and Dr. Konrad Steffen (CIRES) -- full bios and program summary available here. I will post their presentations when AMS puts them online (which will be here).

I have spent a great deal of time studying the ice and sea-level-rise issue (see links below) and still found the presentations informative and startling. It is very safe to say the Arctic Sea will be essentially ice-free by 2030, and I'd personally bet on 2020 -- any takers?
