Threat to the ozone layer by future volcanic eruptions greater than previously thought

As the CFCs slowly degrade over the coming decades, so too should the volcano’s ozone-destroying power. However, new research shows that the volcanic risk to the ozone layer will persist for decades longer than previously believed.

Mountain glaciers recharge vital aquifers

Small mountain glaciers play a big role in recharging vital aquifers and in keeping rivers flowing during the winter, according to a new study. It suggests that the accelerated melting of mountain glaciers in recent decades may explain why arctic and subarctic rivers have increased their water flow during the winter even without a correlative increase in rain or snowfall.

Greenland’s summer ocean bloom likely fueled by iron

Iron particles catching a ride on glacial meltwater washed out to sea by drifting currents is likely fueling a recently discovered summer algal bloom off the southern coast of Greenland, a new study finds. Microalgae, also known as phytoplankton, are plant-like, marine microorganisms that form the base of the food web in many parts of the ocean.

Extraordinary storms caused massive Antarctic sea ice loss in 2016

Antarctic sea ice – frozen ocean water that rings the southernmost continent – has grown over the past few decades but declined sharply in late 2016. By March of 2017 – the end of the Southern Hemisphere’s summer – Antarctic sea ice had reached its lowest area since records began in 1978. Puzzled scientists wanted to know why.

New study evaluates efficiency of oceans as heat sink, atmospheric gases sponge (plus video)

A new study is one the first to estimate how much and how quickly the ocean absorbs atmospheric gases and contrast it with the efficiency of heat absorption. Using two computer models that simulate the ocean, scientists found that gases are more easily absorbed over time than heat energy.

Some clouds filled with ice lollipops

A cloud full of lollipops may sound like the most delicious carnival treat ever… except this cloud’s lollipops are made of ice. Scientists spotted the lollipop-shaped ice crystals during a research flight in southwest England. The researchers flew through a large cloud system in 2009 to better understand how ice forms at relatively mild temperatures.

Offshore wind turbines vulnerable to Category 5 hurricane gusts

Offshore wind turbines built according to current standards may not be able to withstand the powerful gusts of a Category 5 hurricane, creating potential risk for any such turbines built in hurricane-prone areas, new University of Colorado Boulder-led research shows. The study, which was conducted in collaboration with the National Center for Atmospheric Research in Boulder, Colorado and the U.S. Department of Energy’s National Renewable Energy Laboratory in Golden, Colorado, highlights the limitations of current turbine design and could provide guidance for manufacturers and engineers looking to build more hurricane-resilient turbines in the future.

Study sheds new light on future of key Antarctic glacier

Thwaites Glacier’s ice loss may not progress as quickly as thought By Carol Rasmussen The melt rate of West Antarctica’s Thwaites Glacier is an important concern, because this glacier alone is currently responsible for about 1 percent of global sea level rise. A new study finds that Thwaites’ ice loss will continue, but not quite as rapidly as previous studies have estimated. The new study, published in Geophysical Research Letters, …

What caused the most toxic algal bloom ever observed in Monterey Bay?

In late spring 2015, the West Coast of North America experienced one of the most toxic algal blooms on record. A new study shows that, at least in Monterey Bay, California, the diatoms in this bloom became particularly toxic because of an unusually low ratio of silicate to nitrate in the waters of the bay.

Scientists discover new mode of ice loss in Greenland

A new study finds that during Greenland’s hottest summers on record, 2010 and 2012, the ice in Rink Glacier on the island’s west coast didn’t just melt faster than usual, it slid through the glacier’s interior in a gigantic wave, like a warmed freezer pop sliding out of its plastic casing. The wave persisted for four months, with ice from upstream continuing to move down to replace the missing mass for at least four more months.
