Without hot rock, much of North America would be underwater

“If you subtracted the heat that keeps North American elevations high, most of the continent would be below sea level, except the high Rocky Mountains, the Sierra Nevada and the Pacific Northwest west of the Cascade Range,” says study co-author Derrick Hasterok, a University of Utah doctoral student in geology and geophysics.

“We have shown for the first time that temperature differences within the Earth’s crust and upper mantle explain about half of the elevation of any given place in North America,” with most of the rest due to differences in what the rocks are made of, says the other co-author, David Chapman, a professor of geology and geophysics, and dean of the University of Utah Graduate School.

A bad explanation is better than none at all

This week Sydney had the perfect storm: the one that didn't happen. The Bureau of Meteorology said we should have been struck by a gale of 100kmh winds about 5am Wednesday. It didn't happen. The experts were wrong.

Nassim Nicholas Taleb, says our lives are surrounded by a miasma of false predictions and forecasts. As a result, much of the medium- or long-term planning done by individuals, companies and governments is of dubious value.

Taleb, once a trader on the finance markets, now has one of the best job descriptions I've heard. He is a professor in the sciences of uncertainty at the University of Massachusetts Amherst.

The world's habitable spaces are under pressure

"Once you cut off the water from the marshes, they die a slow death," Alwash said. "Saddam could not wait for the marshes to die slowly. He started burning the reeds to flush out the resistance and kill all the wildlife so people would not have an ability to survive."

Reflooding of some Iraqi wetlands began immediately after Hussein was ousted in April 2003, and local and international scientists started planning the reconstruction. This attempt has been more successful than anticipated; in December 2006, satellite photos revealed that nearly 50 percent of the marshes had been restored.

Surge in hurricane activity is only a return to normal: study

Okay. I am baffled.
Ten days ago we had Kerry Emanuel quoted as saying "There has been a large upswing in the frequency of Atlantic hurricanes, beginning in 1995," Emanuel said on his Web site, http://wind.mit.edu/~emanuel/anthro2.htm. "This corresponds to an upswing in tropical North Atlantic sea surface temperature, which is very likely a response to increasing anthropogenic (human-caused) greenhouse gases." Source

Now PhysOrg has this " Investigators believe the greenhouse effect cannot be blamed for a surge in hurricane activity since the mid-1990s."
and

"The phase of enhanced hurricane activity since 1995 is not unusual compared to other periods of high hurricane activity in the record," they report on Thursday in Nature, the weekly British science journal.

Sediment core links monsoons to global climate evolution

"Monsoons, the life-giving, torrential rains of Asia and Africa, have an ancient, unsuspected connection to previous Ice Age climate cycles, according to scientists at the University of California, Santa Barbara, and at Kiel University in Germany."

Climate (along with Brain Science) is the most complex subject human beings have ever attempted to comprehend.

El Nino And African Monsoon Have Strongly Influenced Intense Hurricane Frequency In The Past

“The processes that govern the formation, intensity, and track of Atlantic hurricanes are still poorly understood,” said Donnelly, an associate scientist in the WHOI Department of Geology and Geophysics. “Based on this work, we now think that there may be some sort of basin-wide ‘on-off switch’ for intense hurricanes.”

From ScienceDaily

And from Reuters by way of Planet Ark:

" Intense hurricanes hit when local sea surface temperatures were warm or cool. In fact, "the Caribbean experienced a relatively active interval of intense hurricanes for more than a millennium when local sea surface temperatures were on average cooler than modern," the study said."

NOAA announces next solar storm cycle will likely start next March

From NASA:
In the cycle forecast issued Wednesday, half of the panel predicts a moderately strong cycle of 140 sunspots, plus or minus 20, expected to peak in October 2011. The other half predicts a moderately weak cycle of 90 sunspots, plus or minus 10, peaking in August 2012. An average solar cycle ranges from 75 to 155 sunspots. The late decline of Cycle 23 has helped shift the panel away from its earlier leaning toward a strong Cycle 24. Now the group is evenly split between strong and weak.

I had trouble deciding whether to post this on the economics site or here, so I did both. I've been thinking about cumulative errors for a month, it's time to let it go. This is by a guy who seems to know his way around an abacus.

I'm encouraged that Mr. Hansen believes in publishing in open access forums like the PNAS and the arXiv (see below). This is the only paper I've ever seen wherein the author refers to his Senate testimony. I should probably start posting his stuff on the Politics and Economics blog.

Remember: Correlation does not equal causation. Just because it appears that temperature rise precedes CO2 rise, don't assume that it has anything to do with the diminished CO2 load carrying capacity of warmer water. Or partial pressures. Anyway, the resolution of the charts isn't fine enough.
