Get used to natural catastrophes

leave a comment »

From Science Daily:

The catastrophic fires that are sweeping Southern California are consistent with what climate change models have been predicting for years, experts say, and they may be just a prelude to many more such events in the future — as vegetation grows heavier than usual and then ignites during prolonged drought periods.

“This is exactly what we’ve been projecting to happen, both in short-term fire forecasts for this year and the longer term patterns that can be linked to global climate change,” said Ronald Neilson, a professor at Oregon State University and bioclimatologist with the USDA Forest Service.

“You can’t look at one event such as this and say with certainty that it was caused by a changing climate,” said Neilson, who was also a contributor to publications of the Intergovernmental Panel on Climate Change, a co-recipient earlier this month of the 2007 Nobel Peace Prize.

“But things just like this are consistent with what the latest modeling shows,” Neilson said, “and may be another piece of evidence that climate change is a reality, one with serious effects.”

The latest models, Neilson said, suggest that parts of the United States may be experiencing longer-term precipitation patterns — less year-to-year variability, but rather several wet years in a row followed by several that are drier than normal.

“As the planet warms, more water is getting evaporated from the oceans and all that water has to come down somewhere as precipitation,” said Neilson. “That can lead, at times, to heavier vegetation loads popping up and creation of a tremendous fuel load. But the warmth and other climatic forces are also going to create periodic droughts. If you get an ignition source during these periods, the fires can just become explosive.”

The problems can be compounded, Neilson said, by El Niño or La Nina events. A La Niña episode that’s currently under way is probably amplifying the Southern California drought, he said. But when rains return for a period of years, the burned vegetation may inevitably re-grow to very dense levels.

“In the future, catastrophic fires such as those going on now in California may simply be a normal part of the landscape,” said Neilson.

Calorie-restricted diets

with one comment

They seem to work, but they would be very difficult, I think.

Severely restricting calories leads to a longer life, scientists say they have proved.

New research now has shown for the first time that such a diet also can maintain physical fitness into advanced age, slowing the seemingly inevitable progression to physical disability and loss of independence.

The study, using a rat model of life-time caloric restriction, showed that the diet reduces the amount of visceral fat, which expresses inflammatory factors that in humans cause chronic disease and a decline in physical performance and vitality across the lifespan.

The study appears in the October issue of Journals of Gerontology Series A: Biological Sciences and Medical Sciences.

Have we finally discovered the Fountain of Youth? No. But we may be getting a little closer.

“This is the first study to report that caloric restriction reduced production in visceral fat of the inflammatory cytokine IL-6 and enhanced performance on overall physical function assessments,” said Tongjian You, Ph.D., assistant professor of exercise and nutrition sciences in the UB School of Public Health and Health Professions and principal investigator.

“In addition, rats that ate a normal diet lost a significant amount of lean muscle mass and acquired more fat, while calorie-restricted rats maintained lean muscle mass as they aged.”

Free rice: play a game and feed the hungry

with 2 comments

From Treehugger:

FreeRice is a computer game that tests your vocabulary and for every word that you get right, 10 grains of rice are donated through the United Nations to end world hunger.

Curious? It’s simple: a word pops up with multiple choice answers. If you click the right one then a harder word comes up and the level of difficulty keeps increasing. For every click 10 grains of rice are donated to the United Nations World Food Programme. Since October 7, 2007 when it began, 164,650,960 grains of rice have been donated.

The site is funded by the advertisers: Macy’s, Fujitsu, Timelife, Apple, Office Depot, Reader’s Digest and many more whose names pop up as you play the game. The World Food Programme is the world’s largest food aid agency, working with over 1,000 other organizations in over 75 countries. Sounds good, so if you are bored, start playing and help the hungry while you’re at it.

Depleted uranium munitions and the downside

leave a comment »

Depleted uranium has long been a favorite of the military: the density of the DU (70% denser than lead) makes it desirable as armor and, more commonly, as armor-piercing ammunition. From Wikipedia:

Most military use of depleted uranium has been as 30 mm and smaller ordnance…

Another use of depleted uranium is in kinetic energy penetrators anti-armor role. Kinetic energy penetrator rounds consist of a long, relatively thin penetrator surrounded by discarding sabot. Two materials lend themselves to penetrator construction: tungsten and depleted uranium…

Note also that according to recent research,[10] at least some of the most promising tungsten alloys which have been considered as replacement for depleted uranium in penetrator ammunitions, such as tungsten-cobalt or tungsten-nickel-cobalt alloys, possess extreme carcinogenic properties, which by far exceed those (confirmed or suspected) of depleted uranium itself: 100% of rats implanted with a pellet of such alloys developed lethal rhabdomyosarcoma within a few weeks.

On more properly military grounds, depleted uranium is favored for the penetrator because it is self-sharpening and pyrophoric. On impact with a hard target, such as an armoured vehicle, the nose of the rod fractures in such a way that it remains sharp. The impact and subsequent release of heat energy causes it to disintegrate to dust and burn when it reaches air because of its pyrophoric properties (compare to ferrocerium). When a DU penetrator reaches the interior of an armored vehicle, it catches fire, often igniting ammunition and fuel, killing the crew, and possibly causing the vehicle to explode...

Jay Rockefeller: sells his vote cheap

with 2 comments

I blogged yesterday about how Senator Jay Rockefeller (D-WV) took $40,000 from two telecoms, and subsequently had his committee include in the FISA bill wholesale immunity for telecoms for their lawbreaking, whatever it might have been. (It’s still not known exactly what they did, but that’s okay with Jay: he got his $40,000.)

Now his spokesperson of course denied the quid pro quo:

“Any suggestion that Senator Rockefeller would make policy decisions based on campaign contributions is patently false,” Wendy Morigi, a spokeswoman for him, said. “He made his decision to support limited immunity based on the Intelligence Committee’s careful review of the situation and our national security interests.”

So Wendy says that the fact that Jay got $40,000 and then went along with what the donors wanted is just a coincidence. Really, the two are not connected.

But that’s stupid, right? It’s quite obvious that the telecoms don’t hand out $40K for nothing. They wanted something for that money, and Jay delivered. The connection is patently obvious. And the telecoms got a terrific bargain: $40K is a less than a drop in the bucket for those businesses. Of course, it was quite a nice windfall for Jay. And he did show his appreciation in the way he worked for them.

This just totally stinks. How can his office deny the connection? It’s as obvious as shit on a plate.

UPDATE: BTW, isn’t it obvious that any legislator (or judge, in those states where judges run for election) would be stark mad to accept large donations from parties who will be affected by decisions currently being considered by the legislator (or judge)? Taking any such donation is simply seeking trouble—or, more to the point, seeking cash in exchange for votes/decisions.

And the results of Bush’s economic policies?

with one comment

Take a look:

The head of the International Monetary Fund, Rodrigo Rato, warned Monday of a potential “abrupt fall” in the US dollar that could roil the global economy.

“There are risks that an abrupt fall in the dollar could either be triggered by, or itself trigger, a loss of confidence in dollar assets,” Rato said at the close of annual meetings here of the IMF and the World Bank.

The outgoing IMF managing director spoke here as the European single currency hit a new high of 1.4347 dollars and global equity markets plunged amid renewed fears a US credit crunch could pitch the world’s biggest economy into recession.

“The uncertainty … comes from downside risks that are much higher than they were six months ago. The turbulence in the credit markets is a warning that we cannot take the benign (global) economic environment of recent years for granted,” Rato said on the final day of the annual meetings of the IMF and the World Bank.

“We still do not know the full effects of the decline in the housing market and the subprime problems of the US economy. Further disruption in financial markets and further falls in housing prices could lead to a global economic downturn,” he said.

Bush, the big spender (unless it might help poor people)

with 4 comments

Bush is willing to spend any amount, just so long as the money doesn’t go to help the poor or the ill (vetoes of stem-cell research, S-CHIP expansion). Take a look:

Bush spends

George W. Bush, despite all his recent bravado about being an apostle of small government and budget-slashing, is the biggest spending president since Lyndon B. Johnson. In fact, he’s arguably an even bigger spender than LBJ.

“He’s a big government guy,” said Stephen Slivinski, the director of budget studies at Cato Institute, a libertarian research group.

The numbers are clear, credible and conclusive, added David Keating, the executive director of the Club for Growth, a budget-watchdog group.

“He’s a big spender,” Keating said. “No question about it.”

Take almost any yardstick and Bush generally exceeds the spending of his predecessors.
