THE HOCKEY SCHTICK: New paper finds another non-hockey-stick in Arctic Siberia
A new paper published in Palaeogeography, Palaeoclimatology, Palaeoecology reconstructs temperatures in Arctic Siberia over the past 15,000 years and finds another non-hockey-stick with temperatures ~2C higher than the present during the early to mid Holocene [9,000 to 4,000 years ago].Study: 20,000 ppm CO2 sustained life on Earth 3 billion years ago | JunkScience.com
Another solution to achieving a habitable but slightly cooler climate under the faint sun conditions is for the Archean atmosphere to have contained roughly 15,000 to 20,000 ppm of CO2 and no methane, said Wolf. “Our results indicate that a weak version of the faint young sun paradox, requiring only that some portion of the planet’s surface maintain liquid water, may be resolved with moderate greenhouse gas inventories,” the authors wrote in Astrobiology.Another Day, Another Mile | Real Science
“Even if half of Earth’s surface was below freezing back in the Archean and half was above freezing, it still would have constituted a habitable planet since at least 50 percent of the ocean would have remained open,” said Wolf. “Most scientists have not considered that there might have been a middle ground for the climate of the Archean.
They only have another 1,500 miles to cover in the next six weeks – and are screaming along at one or two miles per day. And they are still in the river delta nowhere near the ice.Lomborg: “Electric Cars Don’t Solve The Automobile’s Environmental Problems…Are More Polluting”
I’ve always wondered about all the huge mining operations that would be necessary to get the materials to manufacture hundreds of millions of huge batteries. Never mind the storage systems needed for storing electricity for the home. Caterpillar is probably drooling over the potential.
Of course we need to develop this technology, but God forbid we force a technology that is nowhere near ready and end up doing real damage to the planet.
