Study Suggests Climate Models Underestimate Future Warming

Scientists have found evidence that tropical Atlantic Ocean temperatures may have once reached 107°F (42°C)—about 25°F (14°C) higher than ocean temperatures today and warmer than a hot tub. The surprisingly high ocean temperatures, the warmest estimates to date for any place on Earth, occurred millions of year ago when carbon dioxide levels in Earth’s atmosphere were also high, but researchers say they may be an indication th

A leading group of epidemiologists, veterinarians and ecologists report that humans are affecting the oceans in ways that are changing the dynamics of disease. Previously harmless pathogens are becoming killers when combined with contaminants; “good” parasites that invisibly control the balance of species in an ecosystem are disappearing; and changes in sea surface temperature can trigger cholera outbreaks thousands of miles away.

“Human activities are knocking things out of balance,” says

Diseases May be Early Warning Sign for Humans Say Scientists

St. Louis, MO (AAAS Annual Meeting, Press Conference: Saturday, Feb. 18th, 9 am Central Time) – Leading scientists, physicians, and veterinarians are uncovering new links between land-based pollution and diseases in marine mammals, with implications for human health.

“Marine mammals are providing early clues of our unseen impact on the sea,” says Paul Sandifer, Chief Scientist for the new Oceans and Human Health

We’re on the brink of the era of deep ocean mining, says a global pioneer in the study of sea floor mineral deposits. Dr. Steven Scott, a geologist at the University of Toronto, in Toronto, Canada says that advances in marine geology and deep ocean technology have combined to make it realistic to go more than two kilometres underwater for gold and other mineral treasures.

It’s a transformation that he says has evoked a knee-jerk reaction over the possible environmental impacts

Whether it’s monkeys and AIDS or mosquitoes and the West Nile Virus, we’re used to thinking of wildlife as reservoirs for emerging infectious human diseases. But a Canadian mathematical biologist says that it’s time that we turned the tables – as often as not, it’s humans that are making the wildlife sick, often to our own detriment.

It’s a 180-degree turn in perspective that Dr. Mark Lewis says is critical to our understanding of emerging infectious diseases of both wildlife and h
