Marine Ecosystems Growing Too Hot for Oysters?

Yet another food source supporting the human population at risk.
And many still can't see nature as our support system.

Researchers scramble to deal with dying oysters
A bacterium explodes in numbers, killing oyster larvae before they can grow
MICHAEL MILSTEIN

An invisible microbe that thrives in warm ocean
water has undermined the Northwest's prized
oyster supply, killing billions of young larvae
that mature into the succulent shellfish known
across the world.

The bacterium, Vibrio tubiashii, is related to
another species that can sicken people who eat
raw shellfish. This one doesn't bother people --
it kills shellfish in their larval stage, before
they latch onto rocks to grow.

Natural Lab Shows Ocean’s Path to CO2-Induced Acidity

Natural lab shows sea’s acid path

By Richard Black
Environment correspondent, BBC News website

Natural carbon dioxide vents on the sea floor are
showing scientists how carbon emissions will affect
marine life.

Dissolved CO2 makes water more acidic, and around the
vents, researchers saw a fall in species numbers, and
snails with their shells disintegrating.

Writing in the journal Nature, the UK scientists
suggest these impacts are likely to be seen across the
world as CO2 levels rise in the atmosphere.

Some of the extra CO2 emitted enters the oceans,
acidifying waters globally.

Book Review: The Great Warming: Climate Change and the Rise and Fall of Civilizations

———————————————————-
“Drought doesn’t usually get much attention in
concerns over melting icecaps, rising sea levels,
toxic UV rays and poisonous air. But … Fagan’s
The Great Warming examines what’s known as the
Medieval Warming Period (MWP), a sort of trial
run for the present.”

The Great Warming:
Climate Change and the Rise and Fall of Civilizations
by Brian Fagan
Bloomsbury,
282 pages, $29.95
————————-

Brian Fagan, the leading authority on the
interaction of climate and human society, has
noticed that there’s a little detail that tends
to get lost in all the dire predictions of global
warming. Fagan is professor emeritus of
anthropology at the University of California and
editor of The Oxford Companion to Archaeology,
and has something like 21 books to his credit,
including Fish on Friday: Feasting, Fasting and
the Discovery of the New World. His latest, The
Great Warming: Climate Change and the Rise and
Fall of Civilizations, is about drought caused by
climate change.

Powerful Storms Swamp Midwest; Spawn Tornadoes, Floods

Powerful storms swamp U.S. Midwest, spawn tornadoes
Sat Jun 7, 2008 11:43pm EDT

CHICAGO (Reuters) – Heavy rains caused flooding that forced hundreds of evacuations in Indiana, and a tornado raked Chicago’s suburbs on Saturday as violent thunderstorms pummeled the already soggy U.S. heartland, authorities said.

The U.S. Coast Guard was called out to help rescue stranded homeowners and motorists, and near-record flooding was forecast for rivers and creeks in western and central Indiana.

“We are getting a lot of rain and water. There are a lot of roads that are impassable. We are urging people to sit tight and stay off the roads,” said John Erickson of Indiana’s Department of Homeland Security.
