The risk of a severe, multi-decade drought hitting the Southwest United States by the end of the century could reach as high as 99 percent if greenhouse gas emissions continue along current lines, says a paper by a team of scientists from Cornell University, Columbia University and NASA.
Human-induced climate change has doubled forest fire damage in the West over the past 30 years, says a study published online early by the journal PNAS. But human effects on fire extend far beyond climate.
Using a technique called satellite radar interferometry, researchers have spotted millimeter-scale ground uplift surrounding four high-pressure injection wells near the eastern Texas city of Timpson. Two of the wells were located directly above a spate of record quakes that struck Timpson in 2012, topping out with a 4.8 magnitude quake on May 17. The other two were located within six miles of the quakes.
Scientists studying dwarf planet Ceres have found that a 13,000-foot volcano there arose not from silicic magma, but from muddy, salty ice that rose to the ~160 K surface and quick-froze like Smucker’s® Magic Shell.
Finding such a dramatic cryovolcanic process this close to the sun – in the inner asteroid belt between Mars and Jupiter – is unusual, and bolsters the idea that Ceres might have originated in the outer solar system. It also lends credence to the notion that asteroids and comets might be more closely related than once thought.
