As the Earth warms, many species are likely to disappear, often because of changing disease dynamics. Here we show that a recent mass extinction associated with pathogen outbreaks is tied to global warming. Seventeen years ago, in the mountains of Costa Rica, the Monteverde harlequin frog (Atelopus sp.) vanished along with the golden toad (Bufo periglenes). An estimated 67% of the 110 or so species of Atelopus, which are endemic to the American tropics, have met the same fate, and a pathogenic chytrid fungus (Batrachochytrium dendrobatidis) is implicated. Analysing the timing of losses in relation to changes in sea surface and air temperatures, we conclude with 'very high confidence' (> 99%, following the Intergovernmental Panel on Climate Change, IPCC) that large-scale warming is a key factor in the disappearances. We propose that temperatures at many highland localities are shifting towards the growth optimum of Batrachochytrium, thus encouraging outbreaks. With climate change promoting infectious disease and eroding biodiversity, the urgency of reducing greenhouse-gas concentrations is now undeniable.
Evidence for these assumptions seems pertty weak. All they did was look at temp. changes in the area and look for correlations with extinctions/declines. A much more in depth study concluded the opposite.
The area had no evidence of climate anomalies in 2004; its temperature and rainfall patterns were similar to those found in longstanding records.
"These results support a model of amphibian declines in which this fungus enters and quickly spreads through a community with no previously infected individuals," Lips said.

Sorry, so sorry, I was thinking this was about the extinction of Frogs --> like French people. I'll move on here just another global warming story.
Speaking of global warming:
the high here in North Texas was 58F;
record high for the date was 88F - in 1932
record low for the date was 7F - in 1933!
I'm sure the fact that people are tromping all over the damned place, dragging fungus spores to new locations, has nothing to do with this.....
My parents were married in 1933 and my sister was born in 1934. The stories in the family are about how horrible the weather was in the "Dust-Bowl" years. The summers were hot, the hottest ever and of course there was no air-conditioning. The sky was often black with dust and the sun couldn't be seen in the middle of the day and it was hard to breath especially for old people.
But I don't think that the memories of the Dust-Bowl get talked about too much anymore.
C'mon out to my farm ponds around the end of February and you'll find at least half of the missing frogs. The croaking is deafening...
Global warming, SUV's, Karl Rove, President Bush and handguns are all conspiring to exterminate frogs.
In your list of reasons for global warming you need to include bottled water. I've just picked this up in the last several weeks -- the progressives are protesting on the amount of energy that we use bottling water. Seems we need to dring tap water to save the planet??
Very true. Crazy weather, global warming happens..... How about that for a bumper sticker..."Global Warming Happens"
For which they got a grant and an article in Nature. No ulterior motives there, nope, couldn't be.

The funny thing is weather and climate data is so easily manipulated. Pretty easy to find a correlate between events when only viewing a small window of time.
Pregnancy test may lie behind deadly frog fungus (NOT Global Warming!)
Your not saying that Marxist are manipulating this "Global Warming" event for their own motives?
We are told over and over that scientists only observe and analyze the data and don't manipulate anything.
This says it all...."We are told over and over that scientists only observe and analyze the data and don't manipulate anything."
There is no worry though, they discovered a whole bunch of new species of "animals" (even some real ones with fur and stuff) in India, as well as in a cave right here in the USA a few weeks ago, so we are ahead of the game with a net gain.
S'OK, they just found a dozen NEW kinda frogs and butterfly's and such in Indonesia...
Funny thing about this "global warming". The evidence shows the earth was much warmer before. We aren't near as warm as we used to be. The ice age (caused by a global catastrophe) is still receeding. They are finding all sorts of rhino's and elephants which were buried suddenly (perfectly preserved with flesh still edible) in Syberia. Along with wolves foxes and rabbits, remains of lush tropical vegetation.
