What Are Mass Extinctions, and What Causes Them? 0919 - 4 out of 5 were due to great CO2 outgassing from volcanic events (120,000 to 800,000 cubic miles of eruptions over millennia).  The 5th, the most recent, was mostly by an asteroid.  It wiped out 75-90% of species on Earth.   252 Mya was the worst, with the only great insect wipeout.  96% of marine species went extinct, sea surface temperatures were up to 104°F (40°C) 1.5 My later, and 76% of dissoved oxygen disappeared.

The Animals That Will Survive Climate Change 0819 - reproduce often, non-specialized diets, smaller, mobile, tolerate heat, alter mating season, etc.

Climate Change Outruns Evolution 0719 - Rate of climate change over next century will be ~10,000 times as fast as observed rate of species change over time.

6th Great Extinction 0307  Climate has played a critical role in past fluctuations of biodiversity levels.  Among the 5 recognized mass extinction events -- Ordovician, Devonian, Permian, Triassic, and Cretaceous -- at least 4 are correlated to climate change….  "For the Permian, the greatest mass extinction on record, … global warming ... produced temperatures 1 - 30°C (18-54°F) higher than today.  It wiped out 95% of ocean life forms and almost 75% of terrestrial species."

Extinction Rates, Today vs History - May 0110 - PDF


    Graph at below is from page 4

"Species extinction rates, expressed as extinctions per 1,000 species per 1,000 years.  The fossil record tells us that, in the distant past, less than one mammal went extinct every 1,000 years.  In the recent past, the number of extinctions has increased 3 orders of magnitude higher than that of the fossil records."
    That is, mammal extinction rates are hundreds of times (200-500 x) background rates.

Extinctions from Warming 0705

     Only 3 of the 21 large animal species found around San Diego near the end of the most recent ice age are still found there.

     5 more are still found elsewhere.  

     But 62% are now extinct, in only about 10,000 years.
