From the you’ve got to be effing kidding me department come this dead serious essay from “The Conversation”, that hotbed of climate alarmism in Australia which somehow got past bullshit detectors at phys.org.
The money quote sort of tries to talk down the headline, but they leave it wide open as a possibility.

So why don’t we see advanced civilisations swarming across the universe? One problem may be climate change. It is not that advanced civilisations always destroy themselves by over-heating their biospheres (although that is a possibility). Instead, because stars become brighter as they age, most planets with an initially life-friendly climate will become uninhabitably hot long before intelligent life emerges.
The Earth has had 4 billion years of good weather despite our sun burning a lot more fuel than when Earth was formed. We can estimate the amount of warming this should have produced thanks to the scientific effort to predict the consequences of man-made greenhouse-gas emissions.
These models predict that our planet should warm by a few degrees centigrade for each percentage increase in heating at Earth’s surface. This is roughly the increased heating produced by carbon dioxide at the levels expected for the end of the 21st century. (Incidentally, that is where the IPCC prediction of global warming of around 3°C centigrade comes from.)
Is there anything climate change can’t do? I predict effects on black holes next.
On the plus side, Michael Mann must be relieved that the Green Lizards aren’t coming after him.
