Busy start heralds bruising Atlantic hurricane season

The 2008 Atlantic hurricane season is already a month ahead of schedule, portending a rough year for tropical storms for the United States, Caribbean and Central America although most likely not a repeat of the devastating 2005 season.

On average, the fourth storm of the six-month season does not occur until August 29. This year, the fourth, Dolly, formed on July 20 and was on the cusp of becoming a hurricane on Tuesday as it churned through the oil and gas-rich Gulf of Mexico.

"It absolutely does mean something, and we should be looking at it with trepidation," said Jeff Masters, co-founder of meteorological website The Weatherunderground.

Commercially bred bees spread disease to wild bees

Disease spread to wild bees from commercially bred bees used for pollination in agriculture greenhouses may be playing a role in the mysterious decline in North American bee populations, researchers said on Tuesday.

Bees pollinate numerous crops, and scientists have been expressing alarm over their falling numbers in recent years in North America. Experts warn the bee disappearance eventually could harm agriculture and the food supply.

Scientists have been struggling to understand the recent decline in various bee populations in North America. For example, a virus brought from Australia has been implicated in massive honeybee deaths last year.

A lightning strike started a fire yesterday that destroyed a strip shopping plaza near the University of Toledo as a line of thunderstorms swept across northwest Ohio and southeast Michigan causing 10,000 customers to lose power, authorities said.

The plaza at 1205 Westwood Ave., just south of Dorr Street, housed a seasonal location of the tax service franchise, H&R Block, the clothing retailer, L.A. Collections, and the yet-to-open Wings Express restaurant.

Flashback Lightning strike starts house fire in Washington, Illinois, US

Thu, 26 Jun 2008 20:51 UTC
A lightning strike is to blame for a Washington, Illinois house fire this morning. No injuries were reported.

The fire at 301 Hale St. started about 3:30 a.m. after lightning hit a tree, causing the tree to split in half and fall on the house.

Before firefighters arrived, the homeowner, whose name was not immediately available, attempted to put out the blaze with an extinguisher and garden hose. It took firefighters another 20 minutes to douse the fire, which they were able to contain to an upstairs bedroom, Washington Assistant Fire Chief Randy Hurd said.

Amazon River Powers Tropical Ocean's Carbon Sink


Science Daily
Mon, 21 Jul 2008 22:38 UTC
Nutrients from the Amazon River spread well beyond the continental shelf and drive carbon capture in the deep ocean, according to the authors of a multi-year study.

The finding does not change estimates of the oceans' total carbon uptake, but it reveals the surprisingly large role of tropical oceans and major rivers.

The tropical North Atlantic had been considered a net emitter of carbon from the respiration of ocean life. A 2007 study estimated that ocean's contribution to the atmosphere at 30 million tons of carbon annually.

The new study, appearing in PNAS Early Edition the week of July 21, finds that almost all the respiration is offset by organisms called diazotrophs, which pull nitrogen and carbon from the air and use them to make organic solids that sink to the ocean floor.

Adding Lime To Seawater May Cut Carbon Dioxide Levels Back To Pre-industrial Levels


Science Daily
Mon, 21 Jul 2008 22:19 UTC
Scientists say they have found a workable way of reducing carbon dioxide levels in the atmosphere by adding lime to seawater. And they think it has the potential to dramatically reverse CO2 accumulation in the atmosphere, reports Cath O'Driscoll in SCI's Chemistry & Industry magazine.

New research suggests there may be a workable way of reducing carbon dioxide levels in the atmosphere by adding lime to seawater.

Shell is so impressed with the new approach that it is funding an investigation into its economic feasibility. 'We think it's a promising idea,' says Shell's Gilles Bertherin, a coordinator on the project. 'There are potentially huge environmental benefits from addressing climate change -- and adding calcium hydroxide to seawater will also mitigate the effects of ocean acidification, so it should have a positive impact on the marine environment.'

90 Billion Tons Of Microbial Organisms Live In Deep Marine Subsurface: More Archaea Than Bacteria


Science Daily
Mon, 21 Jul 2008 22:07 UTC
Biogeoscientists show evidence of 90 billion tons of microbial organisms--expressed in terms of carbon mass--living in the deep biosphere, in a research article published online by Nature, July 20, 2008. This tonnage corresponds to about one-tenth of the amount of carbon stored globally in tropical rainforests.
