Weather Channel expert on Georgia's record-smashing global-warming-type deluge Posted: 05 Oct 2009 09:39 AM PDT Stu Ostro, Senior Meteorologist at the Weather Channel, has written a must-read post on the recent record Georgia deluges, "Off the chain without a 'cane" (reprinted below). He makes a key point that had not occurred to me about the devastating September rainstorms:
The main point of my post, Hell and High Water hits Georgia, was that, as climate scientists have predicted for a long time, wild climate swings are becoming the norm, in this case with once-in-a-century drought followed by once-in-a-century flooding. Back in 2007, the NYT reported, "For the first time in more than 100 years, much of the Southeast has reached the most severe category of drought…. The situation has gotten so bad that by all of [state climatologist David] Stooksbury's measures — the percentage of moisture in the soil, the flow rate of rivers, inches of rain — this drought has broken every record in Georgia's history." So it was more than a once-in-a-century event. As for the flooding, as one CP commenter posted, the USGS quantified that "the rivers and streams had magnitudes so great that the odds of it happening were less than 0.2 percent in any given year. In other words, there was less than a 1 in 500 chance that parts of Cobb and Douglas counties were going to be hit with such an event." I have called this type of rapid deluge, "global warming type" record rainfall, since it is one of the most basic predictions of climate science — and its an impact that has already been documented to have started. But in fact this deluge is even more of a global-warming-type rain event because, as Ostro notes, unlike typical Georgia deluges, this one was not associated with a tropical storm or hurricane. Ostro is "Senior Director of Weather Communications. Stu leads the team of tornado, hurricane, and climate experts at The Weather Channel." Because these extreme rain events becoming more common, and because Ostro's excellent explanation is really too long and technical to simply excerpt, I'm going to repost the entire thing below: [Note: For ease of reading, I'm not indenting this. Everything below is Ostro.] That's what the weather was in the Atlanta metro area early last week, and things were wiggy in the U.S. for much of September. Usually during that month when there's wild weather, including precipitation extremes, it's as a result of a hurricane or tropical storm. Not in 2009. This "ex-skeptic" hasn't blogged about climate change in a while. For that matter, I haven't blogged about anything for a while! Been a bit distracted, but it's time to jump in the water again. Or maybe I should say, time to dust off my Nomex suit and put it on! Before you fire up the flamethrower, though, let me say what this long entry is NOT about. It's not about H.R. 2454 (more commonly known as the Waxman-Markey bill). And I'm not telling you that you can't drive your SUV. This blog is about the effect of climate change upon day-to-day weather. About physics and thermodynamics not politics. It was two years ago last week that I first thoroughly laid out the basic premise. Nothing that's gone on in the atmosphere since then has convinced me otherwise, and I've continued to add gazillions of weather events to this PDF [56MB file, and now up to 529 slides]. My goal has been and continues to be to document and objectively analyze these cases. There have been anomalies and extremes for as long as there has been weather on the planet; the key is to assess how they are now changing as the climate changes. To review: –The global climate is overall warmer than it was in the 1970s. (That shouldn't be too controversial a statement!) –Technical talk: The atmospheric warming has resulted in an increase in 1000-500 millibar thicknesses. Those increased thicknesses are manifesting themselves primarily by an increase in 500 mb heights (particularly notable in mid-high latitudes of the Northern Hemisphere), as there has not been a similar rise in 1000 mb heights. Although there is of course natural year-to-year variability, the overall trend at 500 mb has clearly been upward. Analogy: It's like bread baking in the oven. As it warms, the dough expands in depth.. Although the details of the science involved are different, the analogy works, which is that the depth (thickness) of a given layer of the atmosphere is increasing on average as that layer warms. Furthermore, in this case, the bottom of that atmospheric layer (1000 millibars) is not significantly changing, just as the bottom of the bread isn't (in that case, it's fixed by the bottom of the pan).
Translation: What we've been observing over and over again in recent years is exceptionally strong ridges of high pressure, sometimes accompanied by strong, persistent "cutoff lows" (upper-level lows cut off from the main jet stream) to the south of the ridges. Over and over and over again, there has been one of those ridges of high pressure bulging northward. One week it might be in Eurasia, the next in North America. Like when you squeeze a kids' squishy ball in one place and then another, as I've done on the air and in talks I've given. For an example of a TWC segment (from July 1, 2009), click on the screen capture below.
The past few months help illustrate all of this. As I recently reported in a TWC segment, it's extremely important to look at the context of this year's cool summer in a portion of North America including the U.S. Midwest! That was a local anomaly of blue dots (below-average temperatures) amidst a sea of red dots (above-average temps). The map is for "climatological summer," or June, July, and August (JJA). And this was occurring in the context of the global temperature rankings.
First, there was the flash flood disaster in Istanbul, produced by what was reportedly the largest amount of rain there in 80 years. The atmospheric circulation signature aloft at the time?
This was occurring at a time when there was an extreme spike in the preliminary satellite-derived globally-averaged mid-tropospheric (600 mb, or 14,000 feet) temperatures to a value which was by far the highest in the ~30-year period of record. Just sayin'.
Global cooling? Fortunately that bizarro cutoff low did not have catastrophic consequences, but while that situation was happening another remarkable weather pattern was unfolding. And this system, like the one in Turkey, would ultimately bring disaster. A persistent mid and upper-level low just sat and meandered and sat and meandered day after day after day over the ArkLaTex and Oklahoma, producing a series of localized deluges from September 9-21 and resulting in record September rainfall in Texarkana and Tuscaloosa.
This all culminated in the flash flood calamity not far from The Weather Channel in the Atlanta suburbs, affecting some TWC employees and causing 10 tragic fatalities in Georgia including one involving a heart-wrenching 911 emergency phone call. Rainfall quickly went off the chain, unheard of for September in Georgia without a hurricane or tropical storm. [Side note: Is El Nino totally to blame for such an exceptionally quiet Atlantic hurricane season? Hmmm.] Many locations in the northern part of the state received more rain in one week than previously on record for the entire month of September, those prior records having been set in 2004, when the remnants of Frances, Ivan and Jeanne brought torrential downpours. Record floods occurred on Suwannee Creek near Suwanee and on the Chattahoochee at Whitesburg. The two images below are from not quite the end of the event, but most of the rain had fallen by then; the first shows the rainfall accumulation at one location and the second is a mapped radar estimate of the amounts.
The pattern at the time on September 20-21:
While it fortunately did not result in any new flood misery, this was the off-the-chain coup de grace meteorologically: a ridge that bulged so strongly for this time of year that it set the record for the highest 500 millibar height so late in the season so far north in the United States (5950 meters at Spokane, Washington). And for icing on the cake, there was yet another cutoff low stuck to the south.
Was all of this just an "accident"? Let's look at the bigger picture. This has happened in the context of overwhelmingly positive 500 mb height anomalies (higher-than-average pressure aloft) so far this year, as has also been the case in recent years. So what does all this mean? Did global warming "cause" the Atlanta flood? Well, the atmosphere is very complex, and with any weather event there's a combination of factors rather than a single one for an outright cause. Additionally, there's no way of knowing what would have happened without the climate having changed. Maybe there would have been an even more extreme and deadly catastrophe by way of a landfalling major hurricane. And large-scale climate drivers didn't determine the small-scale specifics of, for example, my neighborhood having been spared serious flooding while other Atlanta suburbs got hit hard. Nevertheless, there's a straightforward connection in the way the changing climate "set the table" for what happened this September in Atlanta and elsewhere. It behooves us to understand not only theoretical expected increases in heavy precipitation (via relatively slow/linear changes in temperatures, evaporation, and atmospheric moisture) but also how changing circulation patterns are already squeezing out that moisture in extreme doses and affecting weather in other ways. While it's important to consider what may happen in 50 or 100 or 200 years, and debate what should be done about that via H..R. 2454 or other measures, we need to get a grip on what's happening *now*.

Posted: 05 Oct 2009 07:51 AM PDT Last year, Thomas Fingar, then the U.S. intelligence community's top analyst, warned that climate change is among the gravest threats to US national security (see here). This year, John Warner, the former (GOP) chair of the Senate Armed Services committee has been repeating the same warning to anyone who would listen (see here). But some Senate conservatives are deaf to the facts, as E&E News (subs. req'd) reports.
Here is Barrasso's justification, which is intentionally mocking and unintentionally self-mocking [from E&E News (subs. req'd)]:
First off, is Barrasso really saying that the entire mission of the Central intelligence Agency is preventing terrorist attacks? Although he sits on the Foreign Relations Committee, he apparently has no conception of what the CIA does. He strikes me as one of those guys who in the 1990s probably wanted to block the CIA from looking into terrorism, since that was not going to prevent one communist attack on us. Second, although he sits on the Environment and Public Works Committee, he apparently missed all the hearings about climate impacts and how they pose a major national security threat to us — and yes, will help create conditions that foster terrorism. In fact, an unusually savvy new intelligence forecast reported last year should have served as a wake-up call for the largely clueless Establishment:
So by all means, let's ban the CIA from pursuing this issue, even in the most modest way:
Fortunately, not everyone in the Senate has a flatlining EEG.
Duh. Let me end with more from last year's Fingar story:
And yet the federal government spends more than $500 billion a year on military security, and maybe one percent of that on climate or energy security. Fingar is a remarkably broad thinking guy, which may well be why he was our top intelligence analyst. He has the kind of reality-based alarmism that inevitably comes from the genuine understanding of the facts of global warming:
Always glad to see somebody serious understands what is coming (see "NOAA stunner: Climate change "largely irreversible for 1000 years," with permanent Dust Bowls in Southwest and around the globe"). Let's hope some sanity prevails in the Senate. We cannot afford to embrace the conservative policy of unilaterally disarming in the face of this gravest of threats. Related Post: |
Obama willing to attend Copenhagen climate talks Posted: 05 Oct 2009 06:59 AM PDT AT HOME IN MY BASEMENT WEARING SWEATS SINCE MY DAUGHTER WOKE UP EARLY, Oct 5 (ClimateProgress) — Reuters reported this interesting piece of news Friday:
Okay, sure, I'm never going to get the dateline Jeff Mason's story had — but then he's not going to get the one I had! Anyway, I don't think it would be much trouble to extend an invitation to heads of state. After all, VP Gore went to Kyoto in 1997. And then there is that other overseas trip the President made last week (see "If Obama is going to Copenhagen to push Chicago's Olympic bid this week, he has to go in December to push a climate deal, yes?") So he should go, and I think there is a good chance he will. UPDATE: Please note this was a comment by Gibbs, who probably doesn't follow this issue very closely. |
Posted: 05 Oct 2009 05:27 AM PDT Media reports of the death of the clean tech industry have been exaggerated (see "Global recession? Must be time for the media's alternative-energy backlash"). The Cleantech group reported Thursday, third quarter "results for clean technology venture investments in North America, Europe, China and India totaling $1.59 billion across 134 companies." That means total cleantech VC funding this year is already about $3.8 billion — which puts total funding on a pace to exceed every year except 2008! And what has brought about this miraculous recovery:
Thank you President Obama and progressives in Congress (see "Sure Obama stopped the Bush depression, cut taxes for 98% of working families, and jumpstarted the shift to a clean energy economy with a $100 billion in stimulus funds — but what has the green FDR done lately?") Where is the money going? Solar, transportation, green buildings:
Here's a fascinating factoid from the Q2 report:
That will no doubt come as a surprise to the Energy Information Administration, which in April, projected solar thermal power in 2014 will be 790 MW, and in 2030 a paltry 860 MW (see "EIA projects wind at 5% of U.S. electricity in 2012, all renewables at 14%, thanks to Obama stimulus!") EIA does not much like renewables — even those with power purchase agreements (see "World's largest solar plant with thermal storage to be built in Arizona — total of 8500 MW of this core climate solution planned for 2014 in U.S. alone"). We're also seeing the initial public offering market return, which is another major source of funds for cleantech:
This country remains by far the leading source and destination for VC funding:
How do we maintain US leadership in clean tech investment and key technology areas? Pass the clean energy bill. |
NY Times spins the greatest nonstory ever told, suckering UK Guardian into printing utter BS Posted: 04 Oct 2009 04:55 PM PDT Memo to status quo media: We get it, already. You have already written your "Copenhagen has failed" stories, and are just waiting for the flimsiest excuse to "scoop" everyone else. Your desperation to file this as-yet-unwritten story is unbecoming and also perverse, since, as I've argued, prospects for a global deal have never been better. Worse, it is leading to the most dreadful herd-journalism and misreporting imaginable. The following should be a cautionary tale. Andy Revkin took the biggest "dog bites man" nonstory of the year — that Obama will not get a climate bill on his desk this year — and spun it into a major piece in the one-time paper of record, "Obama Aide Concedes Climate Law Must Wait" (online Friday, print Saturday). How old is this supposed news? Well, my very first piece explaining that the torturous process — getting through all of the House committees, then the House floor, then all of the Senate committees, and then Senate floor, and then out of conference to merge the two chambers' bills into one, and then through the House and Senate again — would not put a bill on Obama's desk until 2010 was on Febuary 3, eight months ago (!) — "Breaking: Sen. Boxer makes clear U.S. won't pass a climate bill this year." For the record, though, Obama's aide didn't "concede" anything, with the implication that she was forced to make some sort of damning newsworthy admission. In fact, Browner made this incredibly obvious statement almost as an aside at a confab put on by The Atlantic magazine. The Atlantic thought so little of the supposedly newsworthiness of Browner's statement that they buried it in the middle of their article on her remarks, "Carol Browner: Now is the Time to Move on Climate." In the entire story, Revkin never bothers to explain that for many, many months now the only issue for those who follow DC climate politics has been whether the Senate would pass a climate bill before Copenhagen, not whether a final bill would get onto Obama's desk before Copenhagen. I would note that his colleagues, John Broder and John Kanter, have written stories that are far clearer — and pointed out a while back that the issue was the timing of the Senate vote (see, for instance, this September 20th story). The paper's own editorial desk was so confused that in the print edition's news summary table of contents on page A2, "Inside the Times," the headline was, "Climate Bill Called Unlikely," which would lead any reader just skimming, as most do, utterly misinformed. But the true result of this bad reporting can be seen in the worst climate story of the week, by Suzanne Goldenberg today (Sunday), "US environment correspondent" for the UK Guardian, which apparently was even more desperate to file the first story that Copenhagen has failed and it's all America's fault:
Yes, the quote in fourth paragraph does not support the conclusion in second paragraph. Revkin's failure to explain the distinction between a signed bill on Obama's desk (which is what Browner was talking about) and Senate passage morphed in this piece into utter misinformation. We may well not get a Senate vote before the end of the Copenhagen meeting, it's certainly no better than 50-50 today, but her remarks do not justify what the Guardian wrote, and they certainly don't justify their "Copenhagen has failed" spin:
The Guardian has just set the record for the use of the word "bleak" in a climate article that isn't about the science. In fact, Carol Browner said we've had "very positive" recent international meetings and even the AP, which felt compelled to join the herd with their version of the non-story, "Obama adviser says no climate change law this year," concluded its piece accurately:
Doesn't sound like of very bleak assessment to me. Apparently the Guardian, in its version of the children's game Telephone, never bothered to actually listen to what Browner actually said.. I've blogged many times I don't think that the White House needs to have a signed climate bill — or even Senate passage — for Copenhagen to be successful in the sense of moving international negotiations forward. Remember, for eight years Cheney-Bush not only muzzled climate scientists and blocked domestic action, they actively worked behind the sciences to kill any international deal. It takes a lot of effort to unpoison a well. And we've only had the possibility of serious international negotiations since January. Anyone who thought there would be a final deal, signed and sealed in December, a mere 11 months later, wasn't paying attention to recent history and doesn't appreciate the nature of international negotiations. The fact is, the news from China, India, Japan, and this country is far more positive toward the possibility of agreement than it has been for a decade or longer. But instead we get this unmitigated bullsh!t from the Guardian:
Embarrassingly bad analysis. Browner's remarks, if you actually listen to them, make clear President Obama is committed to achieving domestic action and an international deal. Finally, for the record, back in early February, Greenwire reported:
Now that was news! And while many different statements were uttered by many different people in the subsequent days and weeks, it has been pretty friggin' obvious from the start that Obama would not see a climate bill on his desk this year. And once Senate Environment and Public Works chair Boxer said she wouldn't introduce her draft bill before the August break, that outcome was 100% guaranteed (see my July post "Looks like no Senate vote on climate and clean energy bill until at least November — thank goodness!"). Maybe now that the media has filed their "Copenhagen is dead and America killed it story," they'll actually be able to start covering the real story, which is certainly less tidy, but ultimately both far more accurate and far less bleak. |
