My Perfect Storm hypothesis gets another unfortunate boost.

Report: Seafood faces collapse by 2048
November 2, 2006
WASHINGTON (AP) -- If current trends of overfishing and pollution continue, the populations of just about all seafood face collapse by 2048, a team of ecologists and economists warns in a report in Friday's issue of the journal Science.
"Whether we looked at tide pools or studies over the entire world's ocean, we saw the same picture emerging. In losing species we lose the productivity and stability of entire ecosystems," said the lead author Boris Worm of Dalhousie University in Halifax, Nova Scotia.
"I was shocked and disturbed by how consistent these trends are -- beyond anything we suspected," Worm said.
While the study focused on the oceans, concerns have been expressed by ecologists about threats to fish in the Great Lakes and other lakes, rivers and freshwaters, too.
Worm and an international team spent four years analyzing 32 controlled experiments, other studies from 48 marine protected areas and global catch data from the U.N. Food and Agriculture Organization's database of all fish and invertebrates worldwide from 1950 to 2003.
The scientists also looked at a 1,000-year time series for 12 coastal regions, drawing on data from archives, fishery records, sediment cores and archaeological data.
"At this point 29 percent of fish and seafood species have collapsed -- that is, their catch has declined by 90 percent. It is a very clear trend, and it is accelerating," Worm said. "If the long-term trend continues, all fish and seafood species are projected to collapse within my lifetime -- by 2048."... |

Green House Gases at Record Highs

U.N. says 2005 set greenhouse gas record By ELIANE ENGELER, Associated Press Writer
GENEVA - Heat-trapping greenhouse gases in the atmosphere reached a record high in 2005 and are still increasing, the U.N. weather agency said Friday.
The measurements coordinated by the World Meteorological Organization show that the global average concentrations of carbon dioxide, or CO2, and nitrous oxide, or N2O, reached record levels last year and are expected to increase even further this year, said Geir Braathen, a climate specialist at the Geneva-based agency.
"There is no sign that N2O and CO2 are starting to level off," Braathen said at the global body's European headquarters. "It looks like it will just continue like this for the foreseeable future."
There is 35.4 percent more carbon dioxide since the late 18th century primarily because of human burning for fossil fuels, the WMO statement said.
...A report this week by British government warned that global warming would devastate the world economy on the scale of the world wars and the Great Depression if left unchecked.
...The agency's findings come just ahead of the second meeting of the countries that adhered to the Kyoto Protocol � aimed at capping greenhouse gas emissions and staving off global warming � to be held in Nairobi, Kenya, Nov. 6-17. Under the 1997 Kyoto accord, 35 industrialized nations have committed to reducing emissions by an average 5 percent below 1990 levels by 2012. The United States, the biggest emitter, rejects the agreement.
...On Monday, the U.N. climate treaty secretariat also reported that global greenhouse gas emissions are on the rise, with increased values from 34 industrialized nations between 2000 and 2004. In the United States, source of two-fifths of the industrialized world's greenhouse gases, emissions grew by 1.3 percent in that period, and by almost 16 percent between 1990 and 2004, the U.N. said. |

greed is simply too strong a force in homo sapiens to avert his own extinction.
People and their temporary constructions litter the earth like trash. An army of consumers, eating, exploiting, discarding and polluting every habitable inch of the planets surface.
The causes and the consequences remain invisible to a largely urbanised world population, separated from nature by the technologcal age.
But the end is not far off now. |

Way to posit an argument and turn around and shoot a hole right through it.....
Anyway, it never ceases to amaze how those with a remarkable flare for the obvious manage to propagandize it off as a late-breaking issue...everything counts in large amounts!
Socialogy tells us that man is like mice on crack. |

One of the publications I edit is a commercial fishing trade pub.
I was just commenting this past week that ever story we run could fall under two categories:
Our traditional fishery has been overfished and there aren't any left.
Or
This new fishery we are developing is reporting fewer fish due to climate change pushing them out of our region.
Bloody depressing, I tell ya. |

vacuum-fishing threaten Antarctic waters
WASHINGTON (Reuters) - Pirates seeking Chilean sea bass and fishing vessels that vacuum up tiny shrimp-like creatures that are a staple for whales, seals and penguins are menacing Antarctic waters, environmentalists said on Thursday.

Yangtze and Pearl river estuaries now 'dead zones'
The Yangtze River and Pearl River estuaries have been listed as newly registered "dead zones," according to a study released by the United Nations Environment Programme (UNEP).
Dead zones, or low oxygenated areas in the world's seas and oceans, are places where nutrients from fertilizer runoff, sewage, animal waste and the burning of fossil fuels trigger algae blooms.
The algae blooms need oxygen and remove it from water, endangering other marine life.
The number and size of deoxygenated areas has risen each decade since the 1970s. Experts warn that these areas are fast becoming major threats to fish stocks, and to people who depend upon fisheries for food and livelihoods.
