Study Shatters Alarmist Claims: Climate Change Not Behind Megafauna Extinctions

The alarmist talking point insisting human CO2 emissions and “climate change” have been driving and will continue to drive the Earth’s sixth mass extinction event is not supported by the evidence. [emphasis, links added]

Twenty years ago it was claimed climate change (global warming) would drive the extinction of one million species by 2050.

This presumes that human-induced rates of warming are so accelerated and unprecedentedly fast that species cannot adapt quickly enough.

It’s odd to believe ecosystems can withstand seasonal ±15°C temperature swings from summer to winter, or over six months, but not the 0.005°C per year change since 1860.

A new study indicates the megafauna extinctions over the last 50,000 years – mammoths, giant sloths, giant armadillos, as well as the extinction of Arctic-dwelling horses, rhinos, bison, and camels – occurred primarily due to human occupation and predation in regions we had never been before.

The climate changes over the last tens of thousands of years (for example, the 4-5°C warming across the Northern Hemisphere within a few decades 14,700 years ago, or the 24 abrupt 10-15°C warming events within decades or less across Greenland) had a negligible to nonexistent impact on megafauna extinctions.

“Hence, the global analyses strongly support human causation, and even indicate little or no interaction with climate change, neither in the severity of extinction and decline nor in the timing.”

Perhaps alarmist claims about mass extinction from climate change are, as they say, going the way of the dodo.

    The rapid and extreme temperature changes that caused the Younger Dryas were too extreme. Something hit the Northern ice sheet and threw the pallet out of the glacial period prematurely. In short order the planet dove back into the glacial period until it came out naturally, leading to the Holocene Optimum. The major large species were maladapted to so many changes in such a short time, being spread too thin during the warm period of the Younger Dryas.

    People make this so, so complicated. Look at the amount of Life in the Hot Tropics and the lack of life in the freezing Poles. Nuff’ said.
