The alarmist talking point insisting human CO2 emissions and \u201cclimate change\u201d have been driving and will continue to drive the Earth\u2019s 6th Mass Extinction event is not supported by the evidence.<\/strong><\/h4>\n\n\n\n

Twenty years ago it was claimed climate change (global warming) would drive the extinction of one million species by 2050<\/a><\/strong>. This presumes human-induced rates of warming are so accelerated and unprecedentedly fast that species cannot adapt quickly enough.<\/p>\n\n\n\n

It\u2019s odd to believe ecosystems can withstand seasonal \u00b115\u00b0C temperature swings from summer to winter, or within a span of 6 months, but not the 0.005\u00b0C per year change since 1860<\/a><\/strong>.<\/p>\n\n\n\n

A new study<\/a><\/strong> indicates the megafauna extinctions over the last 50,000 years \u2013 mammoths, giant sloths, giant armadillos, as well as the extinction of Arctic-dwelling horses, rhinos, bison, and camels \u2013 occurred primarily due to human occupation and predation in regions we had never been before.<\/p>\n\n\n\n

The climate changes over the last tens of thousands of years (for example, the 4-5\u00b0C warming across the Northern Hemisphere within a few decades<\/a><\/strong> 14,700 years ago, or the 24 abrupt 10-15\u00b0C warming events within decades or less across Greenland<\/a><\/strong>, had a negligible to non-existent impact on megafauna extinctions.<\/p>\n\n\n\n

\u201cHence, 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.\u201d<\/em><\/p>\n\n\n\n

Perhaps alarmist claims about mass extinction from climate change<\/em> are, as they say, going the way of the dodo.<\/p>\n\n\n\n
