Increasingly, researchers are doing the numbers, and saying, yes, if present trends continue, a mass extinction is very likely underway.
And the crap just keeps on coming. Clearly, you jump on any bandwagon that is driven by a liberal and meets your political standards without regard to any facts. Did you actually do any research on this topic, or did you just link to the first google hit that supported your claims?

In case you need assistance with the math, 1960 would be 50 years ago. So lets look at your "evidence" for the "fact" that extinctions today are the highest they have been for "millions of years".
Tasmanian Tiger – extinct in 1936 but its extinction started long before that. It was eliminated from the mainland 3,000 years ago.

Southern Plains Zebra – Not extinct at all.

Passenger Pigeon - The last one died in 1914

Golden Toad – Last seen in 1991; a victim of chytridiomycosis. . How about that, you got one but it has nothing to do with CO2. I suspect that as we go down the list, there won’t be a single extinction due to climate change.

Caribbean Monk Seal – Last sighted in 1952 although descriptions by uneducated fishermen seem to suggest that it is not, in fact, extinct.

Pyrenean Ibex – The last one died in 2000 although the population was down to 100 by 1900. Hardly a surprise, but lets give you that one as well. 2

Bubal Hartebeast – The last known specimen was killed in the 1920’s
Javan Tiger – May have become extinct in the 1980’s. 3

Tecopa Pupfish – 1978. It was driven into extinction by bath houses being built on the hot springs were it lives. Interesting to note that with one exception (not attributable to man) none of your species have gone extinct due to climate change which was your original premise.
Baiji River Dolphin – Not extinct.

Steller's Sea Cow – The last one was reportedly killed in 1768. Missed the mark there by almost two and a half centuries.
http://www.petermaas.nl/extinct/speciesinfo/stellersseacow.htm
Caspian Tiger – Possibly not extinct (sightings in turkey) and DNA analysis suggests that the Caspian tiger is one in the same as the Siberian tiger.
http://www.petermaas.nl/extinct/speciesinfo/caspiantiger.htm
Clip: Recent genetic research even suggests that the Caspian Tiger never became extinct, but that they are one and the same as the surviving Siberian Tigers (Driscoll et al. 2009).
West African Black Rhino - Once again, hunted to extinction. You do realize don’t you that animals hunted to extinction in no way suggest any sort of mass extinction. Same for animals that are crowded out. Your claims of imminent mass extinction are falling flat. 4
Craugastor escoces - a toad in the forests of Costa Rica - Most likely went extinct due to a disease; chytridiomycosis.
Holdridge's Toad – Again, a victim of chytridiomycosis.
Spix's Macaw – Not extinct.

Black-faced Honeycreeper – Again, dead due to forest cutting and predation by cats. 5
Hawaiian Crow - extinct in the wild- Again, not extinct, and not extinct in the wild.

Shall we mark this down as a fail? Most of your extinctions happened more than 50 years ago, none of them can be attributed to climate change, and some of them aren't even extinct. The claim of extinctions at a rate not seen in millions of years is just one more claim you can't support.
Unbelievable. Do you meditate on this mantra every time someone points out a fact? My statement was that all organic life is composed of inorganic elements and compounds. How is this, in any way, unsupported? For instance, take a look at this diagram of the organic compound benzene:
Do you, or do you not have any rational explanation for how life might have risen from non living substances? Yes or no? We both know the answer is no because we both know that there is no rational explanation. The fact that life is made largely of non living substances is not an explanation for how life might have sprung from non living ingredients.
You have failed yet again. You have not yet successfully substantiated a single point in all these pages.
