Jellyfish Swarm Northward in Warming World

Scientists believe climate change — the warming of oceans — has allowed some of the almost 2,000 jellyfish species to expand their ranges, appear earlier in the year and increase overall numbers, much as warming has helped ticks, bark beetles and other pests to spread to new latitudes.

The gelatinous seaborne creatures are blamed for decimating fishing industries in the Bering and Black seas, forcing the shutdown of seaside power and desalination plants in Japan, the Middle East and Africa, and terrorizing beachgoers worldwide, the U.S. National Science Foundation says.

Yikes!

Yikes!

how could this be? global warming is a hoax, isn't it? as an aside, i've noticed many more jellyfish this year in our home waters.

One problem with this.... the oceans are not warming.

lol..yes, they are.

A U.S. marine scientist, Jennifer Purcell of Western Washington University, has found a correlation between warming and jellyfish on a much larger scale, in at least 11 locations, including the Mediterranean and North seas, and Chesapeake and Narragansett bays.

"It's hard to deny that there is an effect from warming," Purcell said. "There keeps coming up again and again examples of jellyfish populations being high when it's warmer." Some tropical species, on the other hand, appear to decline when water temperatures rise too high.

Even if populations explode, their numbers may be limited in the long term by other factors, including food and currents. In a paper last year, researchers concluded jellyfish numbers in the Bering Sea — which by 2000 were 40 times higher than in 1982 — declined even as temperatures have hit record highs.

So that's it? Jelly fish are breeding more so Global Warming is proven?

No, they aren't..... you are swigging too much kool-aid.

That goes for you too Catz.

There's a main difference between us. I don't accept main stream media's take on this issue. I research and read papers by a variety of scientists.

I won't mention where you two have your heads stuck into.

Some 3,000 scientific robots that are plying the ocean have sent home a puzzling message. These diving instruments suggest that the oceans have not warmed up at all over the past four or five years. That could mean global warming has taken a breather. Or it could mean scientists aren't quite understanding what their robots are telling them.

The Mystery of Global Warming's Missing Heat : NPR

Quote:

Two separate studies through NASA confirm that since 2003, the world's oceans have been losing heat. In the peak of the recent warming trend, 1998 actually ranked 2nd to 1934 as the warmest year on record.

John Willis, an oceanographer at NASA's Jet Propulsion Lab, published his first report about the warming published on NASA's Earth Observatory page this week discussed his and other results. Willis used data from1993-2003 that showed the warm-up and followed the Global Warming Theory. In 2006, he co-piloted a follow-up study led by John Lyman at Pacific Marine Environmental Laboratory in Seattle that updated the time series for 2003-2005. Surprisingly, the ocean seemed to have cooled.

Oceans are cooling according to NASA

Yep, the esteemed research organization Yahoo, says it's so.

what about all the other organizations? do you dismiss them out of hand as well?

how many others would you like to see? NOAA, NASA?

Uhh, maybe you didn't read my post, but the quote was from a NASA paper. Did you dismiss them out of hand as well??
