Tropical Storm Claudette threatens Florida Panhandle

Pensacola Beach - Brewing in the Gulf of Mexico, Tropical Storm Claudette was bringing heavy rain to the Florida Panhandle Sunday, likely becoming the first tropical storm to strike the U.S. mainland this year.

Claudette had winds of at least 50 mph, but was not expected to cause significant flooding or wind damage. Lurking more ominously was Tropical Storm Bill, which was quickly turning into a powerful storm over warm waters in the open Atlantic with sustained winds of 65 mph. Ana, a tropical storm that had also been churning in the Atlantic, had weakened to a depression.

Skies clouded and bands of intermittent heavy rain moved on shore ahead of the storm, but the Panhandle was largely calm.

Condominiums on Pensacola Beach warned residents to bring balcony furniture indoors with winds anticipated to strengthen throughout the evening. A trickle of cars and SUVs with surfboards on top headed east along the Panhandle as surfers hoped to catch waves whipped up by Claudette.

Dry winds, heat fan wildfires across California

Santa Cruz - Hot, dry winds and high temperatures fanned wildfires across California Sunday, pushing firefighters into rugged terrain to contain the flames and guard against new blazes.

"Things are so dry out there that it doesn't take much for a spark or an ember to quickly develop into a wildfire," said CalFire spokesman Daniel Berlant.

A fire near the Santa Cruz mountain communities of Swanton and Bonny Doon was about 50 percent contained Sunday, after burning 10 square miles since Wednesday and leading to mandatory evacuations of about 2,400 residents. The blaze threatened more than 250 homes and had damaged two outbuildings. More crews were arriving to fight the flames, totaling 2,165 firefighters on Sunday.

California Gov. Arnold Schwarzenegger said Santa Cruz's Lockheed Fire was among 11 burning in the state. A state of emergency was declared in the county, while other blazes forced evacuations and knocked out power in other parts of the state.

More Steig Disrespect: Common Decency Goes a Long Way

Here is another tone-deaf incident involving the activist wing of the climate science community that has the effect of making the entire enterprise look corrupt. The short story is that a professor from Ohio State found an error in a paper on Antarctic temperature trends in Nature. He published his analysis of the error on the blog Climate Audit and sent a gracious note to the authors letting them know of his discovery.

What did the authors do? They turned around and submitted the correction to Nature as their own work, and then had it published under their own names without so much as an acknowledgment to the Ohio State professor who actually did the work and made the discovery of the error. In academia this sort of behavior is called plagiarism, pure and simple.

Steve McIntyre at Climate Audit has a very interesting discussion on the giving of credit.

Update: Roger Pielke Jr. blogs on this in rather frank terms:

Changing Perilous Assumptions to Suit the Analysis

In 2007 Michael Mann and colleagues published a paper (PDF) critical of work suggesting an undercount in storms from historical records, claiming that it was "perilous" to assume that there is a "fixed" relationship between landfalling and total hurricanes in the Atlantic basin:
Of course, estimation of undercount based on the assumption of a fixed relationship between total TC counts and the number of landfalling storms is perilous. Such an approach assumes, in particular, that the large-scale atmospheric steering which determines the trajectories of TCs once they've formed is constant, when there is in fact strong evidence that it is highly variable over time . . .
Now Mann and another set of colleagues (PDF) make what appears to be the exact opposite assumption in a paper just out in Nature, that landfalls are "in rough proportion" to overall basin activity:
We compared the sediment-based record against the above statistical estimate of basin-wide tropical cyclone activity (Fig. 3), guided by a working assumption that an appropriately weighted composite of regional landfalling hurricane activity varies, at multidecadal and longer timescales, in rough proportion to basin-wide tropical cyclone activity.

Mann et al. Unsmoothed, Landsea07 Adjusted

UPDATE: I still find this hard to believe, is it possible that Mann has mislabeled his data files such that the smoothed data appears in the annual predictions column in his data file, rather than the raw counts? I find it hard believe that it is otherwise the case.

I was curious how the curve shown in Mann et al. discussed earlier today would look using adjusted data, and thanks to Michael Mann the data is up online allowing a comparison with data adjusted according to work in 2007 by Landsea (i.e., it doesn't include the analysis from Landsea et al. released this week).

I graphed (above) the adjusted data (red curve) along with Mann et al.'s "predicted" historical data (blue curve, based on the Landsea data) both unsmoothed, just to see what it looks like -- using information from these files at Mann's directory:

Scientists mull quiet '09 hurricane season

Hurricane
© Getty ImagesIn December 2008, the National Hurricane Center predicted an above-average hurricane season for 2009. Since then, the organization has downgraded it to a below-average season.

The now iconic image of murky dust rising from a smokestack in the shape of a hurricane on the cover of Al Gore's global warming documentary draws a distinct correlation between rising temperatures and stronger storm patterns.

But here's an inconvenient truth: This year's hurricane season has gotten off to the slowest start in 17 years. And yet global warming alarmists continue to ring their doomsday sirens.

The official start of the hurricane season is June 1. And not since 1992 - the year of Hurricane Andrew - has the Atlantic Ocean been silent past Aug. 4. Meteorologists have yet to name even a single tropical storm in the Atlantic in 2009.

So is global warming really doing anything?

"While it is commonly thought that global warming would increase hurricane activity, that is far from a settled issue," said Rob Eisenson, a meteorologist at Western Connecticut State University. "There are some research studies that suggest global warming would not have that effect."

Chris Landsea: Response to Michael Mann Hurricane Hockey Stick

Dear Michael and tropical storm folks,

I have some additional concerns about this new paper. As you know, I was one of the reviewers for your Nature paper and, as usual, I "signed" my review. Unfortunately, some very large concerns of mine about the paper were not addressed. The two gravest issues are the paper's use of the Atlantic basin tropical storm frequency data without consideration of new studies and the merger of the paleo-tempestology record to the historical storm data. Perhaps these could be addressed here.

The first point is that the paper disregarded (and not even discussed) crucial new work by Vecchi and Knutson (Journal of Climate, 2008) and Landsea, Vecchi, Bengtsson and Knutson (Journal of Climate, 2009). The first paper showed that about 3-4 tropical storms per year were likely "missed" in the late 19th Century down to less than 1 per year by the 1960s. The second paper (provided to you all in the review process as an accepted paper) shows that two-thirds of the massive doubling trend is simply due to very short-lived (< 2 days duration) tropical storms.

Taking out these "shorties" (very likely due just to our vastly improved observational capabilities) from the record and adding in the estimated number of "missed" medium to long-lived tropical storms causes the long-term trend to completely disappear.
