Steven Chu's full global warming interview

I previously blogged on the blunt LAT interview that Energy Secretary Steven Chu gave last week.

Now the reporter, Jim Tankersley, has posted online (here) virtually the entire 40-minute interview, Chu's first since being confirmed as secretary. Tankersley notes that:

Chu isn't a climate scientist -- he's a Nobel-winning physicist -- but he's served on several climate-change commissions, and in his position, will be one of President Obama's point men on the climate issue.

Chu has studied the climate science issue for years and talked to many of the leading climate scientists in coming to his conclusions. His full remarks are well worth reading, as a preview of what to come from team Obama and as an extended breath of fresh air after eight long years of high-level Bush Administration denial and muzzling of U.S. climate scientists:

Rising sea salinates India's Ganges

We are facing catastrophic sea-level rise this century on our current greenhouse gas emissions path.

The direct impact of such sea-level rise is so enormous -- and so easy to show visually -- that other serious ramifications hardly get mentioned at all. So kudos to Reuters for reporting:

KOLKATA, India: Rising sea levels are causing salt water to flow into India's biggest river, threatening its ecosystem and turning vast farmlands barren in the country's east, a climate change expert warned Monday.

Much of the world's cropland -- especially in the developing world -- is close to sea level and near the shore. I haven't seen a global quantification of the impact of salt water infiltration. I did find a 2008 discussion of "Global Warming and Salt Water Intrusion: Bangladesh Perspective," [PDF] which concludes:

'We're looking at a scenario where there's no more agriculture in California,' Part 2

Finally, we have a top administration official telling it like it is. Energy Secretary and Nobelist Steven Chu told a Los Angeles Times reporter:

In a worst case, Chu said, up to 90% of the Sierra snowpack could disappear, all but eliminating a natural storage system for water vital to agriculture.

"I don't think the American public has gripped in its gut what could happen," he said.

Precisely. [You can listen to an interview with the LAT reporter and me on To the Point here.]

We face desertification of perhaps a third of the earth that is "largely irreversible for 1,000 years" -- if homo sapiens are not sapiens enough to sharply and quickly reverse emissions trends. Part 1 looked at the canary-in-the-coal mine for desertification: "Australia faces collapse as climate change kicks in."

But the Southwest from Kansas and Oklahoma to California are right behind Australia, according to a 2007 Science ($ub. req'd) paper:

Here we show that there is a broad consensus among climate models that this region will dry in the 21st century and that the transition to a more arid climate should already be under way. If these models are correct, the levels of aridity of the recent multiyear drought or the Dust Bowl and the 1950s droughts will become the new climatology of the American Southwest within a time frame of years to decades.

[Note: That study "only" modeled the A1B emissions scenario, which leads to 720 ppm by 2100. We are currently on track to 1,000 ppm (see here).]

A December U.S. Geological Survey report also warned that the Southwest faces "permanent drying" by 2050.

Before the permanent drying -- aka a desert -- sets in, you'd expect to see more and longer record-breaking droughts. In fact, Lester Snow, director of California's Department of Water Resources said Friday:

NWF VP believes we'll see a cap-and-trade bill this year, and 'Waltzing Matilda' isn't about dancing

First, one of my favorite tunes, "Waltzing Matilda," has nothing to do with dancing.

Second, somebody out there thinks Congress might actually put a climate bill on Obama's desk this year.

First things first. So I'm singing to my daughter, reworking the lyrics to the "the unofficial national anthem of Australia," to distract her from her quest to watch videos on my PC, and she cleverly asks to see a "Waltzing Matilda video." And this is what I find on YouTube:

Turns out the song is about an Australian hobo, who gives the name Matilda to his swag -- his "bed roll that bundled his belongings." Turns out "waltzing Matilda" is slang for traveling with all one's belongings on one's back.

Given where Australia is headed -- "Australia faces collapse as climate change kicks in" -- and for how long (if we don't act soon and strongly to stop it) -- Climate change "largely irreversible for 1,000 years," with permanent Dust Bowls around the globe -- I'm now thinking that Waltzing Matilda will eventually be the official national anthem of Australia. But I digress.

So who is this mystery person who thinks we are on the fast track for climate action?
