    Gregory Wrightstone: exposing the mass extinction lie

    Reposted from Fabius Maximus Website Larry Kummer, Editor Climate change 24 May 2019 Summary: The latest chapter of the climate campaign consists of warnings about a coming mass extinction of species. Here is a stunning analysis of these claims by Gregory Wrightstone. This made a big impact at Wednesday’s House hearings. I doubt you will…
    I trump WUWT garbage by raising it with science.

    Modern rates of vertebrate extinction were much higher than a background extinction rate of 2 E/MSY. Among the vertebrate taxa evaluated by the International Union of Conservation of Nature (IUCN), 338 extinctions have been documented since 1500 [“extinct” (EX), Table 1]. An additional 279 species have become either “extinct in the wild” (EW) or listed as “possibly extinct” (PE), totaling 617 vertebrate species summed over the three categories. Most extinctions have occurred in the last 114 years (that is, since 1900; Table 1). Our estimated “highly conservative” (that is, using data for EX species only) and “conservative” (that is, by including EX, EW, and PE) modern extinction rates for vertebrates varied from 8 to 100 times higher than the background rate (Table 2). This means, for example, that under the 2 E/MSY background rate, 9 vertebrate extinctions would have been expected since 1900; however, under the conservative rate, 468 more vertebrates have gone extinct than would have if the background rate had persisted across all vertebrates under that period. Specifically, these 468 species include 69 mammal species, 80 bird species, 24 reptiles, 146 amphibians, and 158 fish....

    Our results indicate that modern vertebrate extinctions that occurred since 1500 and 1900 AD would have taken several millennia to occur if the background rate had prevailed. The total number of vertebrate species that went extinct in the last century would have taken about 800 to 10,000 years to disappear under the background rate of 2 E/MSY (Fig. 2). The particularly high losses in the last several decades accentuate the increasing severity of the modern extinction crisis.

    I thought you were gaslighting. Sufficient to say, that is an opinion that is hotly disputed. The length of time it takes to generate hydrocarbons is purely of academic interest and of no practical use. The air is cleaner now than a generation ago. This is pretty much all spin with no substance inside.

    I was hoping for better.

    Nah, I made sure to not drop it on his head, just let it fall down by his feet.

    False. My citation was legit. His was WUWT, a farce site.

    When one is too ignorant to distinguish between quality sources and bad sources... they are just the suckers that the denial industry wants.
    Many Trump supporters have lots of problems, and those deplorables are bringing those problems to us. They’re racists. They’re misogynists. They’re islamophobic. They're xenophobes and homophobes. And some, I assume, are good people.

    Is vertebrate extinction rates indicative of mass extinction though? What about the proliferation of vertebrates species like Rats and House Sparrows? Are ecological niches being left vacant, which would trigger trophic cascade, or are they being filled by invasive organisms?
    And there's no need to worry since everything is mostly nothing;
    or so I'm told by an angel in a white lab coat

    If species going extinct were being replaced by new species, you would have a point. But, what we are seeing is a whittling down of biodiversity.

    It's like leveling the island of Borneo, for example, and replacing ten thousand species of plants with one giant grove of rubber trees. Sure rats and cock roaches are filling gaps left by whatever died out. But, that just means more rats and cockroaches, not more diversity.

    No, your OP has that distinction.
