Changing climate: 10 years after An Inconvenient Truth

 Science News, April 2016

More than 25 years before the star-studded Los Angeles premiere of An Inconvenient Truth, glaciologist Lonnie Thompson was about as far away from the red carpet as possible. It was 1978, and high in the rugged Andes, Thompson and fellow scientists were witnessing the first glimpses of a pending worldwide disaster. Rising temperatures were melting ancient titans of ice and snow. Mammoth glaciers were disappearing at unprecedented rates and withering to the smallest sizes in millennia. The delicate balance of Earth’s climate was upset.

Sea levels could rise twice as fast as previously predicted

 Science News, April 2016

Antarctica’s meltdown could spur sea level rise well beyond current predictions. A new simulation of the continent’s thawing ice suggests that Antarctic melting alone will raise global sea levels by about 64 to 114 centimeters by 2100, scientists report in the March 31 Nature.

Dome effect leaves Chinese megacities under thick haze

 Science News, April 2016

Airborne black carbon, also called soot, can cause the dome effect by warming the atmosphere’s top layer and blocking sunlight that would otherwise warm the surface air. The reduced temperature difference between the two layers lowers the boundary between them. This effect traps pollution around major cities, worsening air quality, new research suggests.

One of Earth’s missing minerals found locked inside meteorite

 Science News, March 2016

The last of a group of dense minerals that make up much of Earth’s crust and upper mantle has been found tucked inside a meteorite that slammed into Australia 135 years ago. The newly discovered mineral, a variety of majorite, is potentially abundant in sinking tectonic plates and could help illuminate the behavior of the deep Earth, its discoverers say.

Quake risk in parts of central U.S. as high as in fault-filled California

 Science News, March 2016

Northern Oklahoma is just as susceptible to a damaging earthquake within the next year as the most quake-prone areas of California. That’s because earthquakes are no longer just a natural hazard, the U.S. Geological Survey says. In its new quake hazards forecast released March 28, the agency for the first time has included artificially triggered seismicity.

Beware of rockfalls in warm weather

 Science News, March 2016

As the weather warms, watch for falling rocks. While monitoring a cracked cliff in Yosemite National Park, researchers watched the fissure widen as temperatures rose. The risk of rockfalls could increase as climate change cranks the thermostat, one scientist predicts.

Wine quality subject to climate change

 Science News, March 2016

Be wary, wine lovers: Climate change can muck with your merlots. By tracking the timing of French and Swiss grape harvests from 1600 through 2007, scientists have discovered that the link between high temperatures and drought conditions — a combination crucial for fine wine production — has broken down since 1980.
