USA – Record-breaking cold gripped the eastern United States on Monday while an icy winter storm crippled the nation’s central states and then ploughed into the mid-Atlantic, dumping snow ahead of Tuesday’s morning commute. Heavy snowfall and ice moving from the Southern Plains eastward pounded Missouri, Arkansas,southern Illinois, Tennessee, Kentucky, Indiana and Ohio. With the storm headed east and sleet and freezing rain expected to also take a swipe at the South, states of emergency were declared in North Carolina, Virginia, Mississippi, Georgia, Kentucky, as well as in Washington, D.C.

Global Warming

Ocean Acidification

Ocean acidification can now be seen from space, highlighting an ongoing danger of climate change and revealing the regions most at risk.

Seawater absorbs about a quarter of the carbon dioxide, a greenhouse gas, that humans release into the atmosphere each year, mostly from the burning of fossil fuels, according to the National Oceanic and Atmospheric Administration (NOAA). This process has slowed the warming of the globe, as all of that carbon is locked up in the ocean’s “carbon sink” rather than floating freely in the atmosphere. But when seawater takes up carbon dioxide, it becomes more acidic. According to NOAA, the surface pH of the ocean has become 30 percent more acidic since the end of the Industrial Revolution.

A map created from the results of satellite gathered information shows the variation apparent across the globe. The redder the colour, the more alkaline, or basic — the opposite of acidic — the region is. The more basic the seawater, the more room it has to absorb carbon dioxide without becoming overly acidic. Open regions of the ocean show this resilience, while many coastal regions appear less alkaline. The northeastern United States looks particularly vulnerable — a finding that echoes 2013 research using on-the-ground measurements.

Ocean acidification eats away at the shells of mussels, oysters and crabs, and baby oysters are already dying in some regions from it. These detrimental effects can carry up the food chain. Meanwhile, researchers worry about direct impacts on non-shelled ocean life as well. A 2013 study published in the journal Proceedings of the Royal Society B found that fish kept in acidic water acted more skittish than fish in normal seawater, which could affect their survival in the wild.

Volcanos

Roundup of Global Volcanic Activity

Chikurachki (Paramushir Island): Ash emissions and explosions of smaller size than the initial one on Sunday evening continue to occur. Ash plumes reported rose to 12-15,000 ft (3.6-4.5 km) altitude.

Colima (Western Mexico): Explosive activity remains elevated. At intervals of tens of minutes to few hours, small to moderate vulcanian explosions occur, often producing ash plumes rising 1-2 km above the crater.

Villarrica (Central Chile): Activity from the summit vent has increased, with an average of 5 strombolian-type explosions per minute observed recently. Bright incandescence is visible above the crater. Yellow preventive alert for the communes Villarrica, Pucón and Curarrehue remains in place by Civil Protection (ONEMI). Access to the crater is closed at the moment.
