Warmists were equally certain that the big frog die-off of a few years ago was due to global warming. They now admit that it was a fungus that caused the problem. Who knows what the real explanation will be this time? We old guys do have pesky memories, don't we? -- JR
When it comes to the hazards of global warming, it may turn out that lizards in burrows are the canaries in the coal mine.
In a study to be published Friday in the journal Science, an international team of biologists reports that in more than one-tenth of the places in Mexico where lizards flourished in 1975, the reptiles now cannot be found. The researchers predict that by 2080, about 40 percent of local lizard populations worldwide will have died off and 20 percent of lizard species will be extinct.
The reason for the huge die-off appears to be rising temperatures. But it isn't heat that is killing the lizards directly.
Instead, global warming appears to be lengthening the period of the day when lizards must seek shelter or risk fatal overheating. In the breeding season, that sheltering period is now so long that females of many species are unable to eat enough food to produce eggs and offspring.
Springs that start earlier and are warmer than they once were have been noted in many regions of the world in the past three decades. The new study suggests that the phenomenon may be far more important for the survival of some animals than peak summer temperatures, said Barry Sinervo, an evolutionary biologist at the University of California at Santa Cruz who headed the 26-person research team...

Oh yeah, that's why lizards are dormant in summer and frolicsome in winter. Tools.
It could be global warming, but again, that's not the point, is it man-caused warming, cooling etc?ReplyDelete
