Rising ocean temperatures linked by some studies to tropical storms are very likely a result of global warming caused by greenhouse gas emissions, according to new research.

The lead author of the new study, Benjamin D. Santer of the Lawrence Livermore National Laboratory of the Energy Department, said the findings suggested that further warming would probably make hurricanes stronger in coming decades.

But while environmentalists and some researchers have asserted that storms like Hurricane Katrina were already measurably stronger because of warming caused by humans, Dr. Santer said his study did not address that issue.

The study was published online yesterday by The Proceedings of the National Academy of Sciences.

The researchers compared a century of observed temperature changes with those produced in more than 80 computer simulations of how oceans respond to natural and human influences on the climate. The simulations were generated on 22 different computer models at 15 different research centers.

The simulations correctly mimicked the cooling caused by plumes from volcanic eruptions, which temporarily block the sun. At the same time, the authors said, the only warming influence that could explain the changes in the oceans was the buildup of heat-trapping smokestack and tailpipe gases in the air.

Earlier studies concluded that greenhouse gases from human activities were warming the oceans, but this analysis was the first to examine thoroughly trends in particular tropical regions of the Atlantic and Pacific Oceans that serve as nurseries for the destructive storms.

Several climate experts said that while debate persisted about the role of warming in pumping up hurricanes, there was little doubt about the long-term trend should warming continue as projected.

“Even under modest scenarios for emissions, we’re talking about sea surface temperature changes in these regions of a couple of degrees,” Dr. Santer said. “That’s much larger than anything we’ve already experienced, and that is worrying.”

Capture and storage of greenhouse emissions from Australia's coal-fired power stations will double the cost of producing electricity and could increase carbon dioxide emissions from power plants by about 30 per cent, CSIRO scientists have told a Federal Government inquiry.
They claim at least 3500 large-scale geosequestration sites across the world would be needed to cut global greenhouse emissions by one billion tonnes of carbon dioxide a year.

So far, Australia has only located 100 sites that could be suitable for underground storage of carbon dioxide.

heres a satellite photo of a hurricane [today] of which 5 years ago we would have heard nothing.Its in the middle of nowhere, not harming anyone ,not on the main shipping lanes[at least in wasn't when it was stronger]and yet the buggers can't wait to include it in this years tally of storms.Its like the storms in N.Oz, the only ones who see these storms are dingos and albabloodytrosses.

The way I look at it hurricanes have always been there. Maybe they are as cyclic as everything else on this earth. But when hurricanes hit poor under developed countries they are relatively ignored, though it has happened many times over. But when the same happens to an industrialised and developed country, the media spins its editorial from every angle, making the story "bigger than life".

Thats true May,last week some 3000 fishermen went missing in the Pacific[most turned up safe later] and they hardly got a mention in the mainstream media.

Australia's Drought Could be Worst in 1,000 Years

CANBERRA - The drought gripping Australia could be the worst in 1,000 years, government officials said on Tuesday, as Australia started to draw up emergency plans to secure long-term water supplies to towns and cities.

So yet again we have the experts having a punch-up :shock: :shock:

Here is an interesting follow up to this post and one that i hope will bring benefits to the folks who suffer from this poisoning.

This is excellent news Forficula, arsenic poisoning in wells can be found everywhere in poor villages throughout India. I just hope its inexpensive (although its low-cost tech, it may still be considered costly by Indian standards), and the government puts this on high priority when the remedy is made available. The poor tends to be overlooked, and unless it serves their agenda, politicians will take their time to implement this.

Bacteria again May, I cant give a link just now but it seems that the soil conditions and make-up are a natural source of arsenic.

And its naturally in the soil? Do villagers die when they drink from the wells? :shock:
