Antarctica faces increasing rainfall threats leading to sea level rise and penguin colony collapse.

Very little is known about rainfall in Antarctica; precipitation falls as snow on the bitter cold ice-covered continent. But during the austral summer of 2013-2014, an Adélie penguin colony near Dumont d’Urville station on coastal Adélie Land experienced “unusual and dramatic rainfall event that occurred on January 1, 2014, and that was...

Thwaites glacier is in extreme peril as warm water is discovered, eroding critical pinning points.

“We might (and I stress might) have already reached and passed a point where there is really no turning back for Thwaites, no matter what we as humans do to our climate,” Alastair Graham, the University of South Florida and co-author of the study. New data from under the ice stream...

The Brunt ice shelf calved an iceberg that is one mile thick and the size of London.

The rift on Antarctica’s Brunt ice shelf has torn itself away from the glacier resulting in a massive iceberg that is known as A74. British Antarctic Survey has been monitoring the glacier for years. The shelf was at its largest extent for over 100 years. The Brits have relocated their research station twice...

Antarctica researchers have become alarmed by a new finding that shows sub-glacial lakes under the Thwaites glacier are draining a significant amount of water to the bedrock under miles thick with ice. Once the lake water reaches the bedrock, it lubricates the glacier enough to create frictional heat at the bed...

Our obliteration of the natural world’s habitats create ideal conditions for pathogens to emerge.

A small remnant of Tallgrass Prairie in Sugarcreek Metro Park, Ohio, The first pioneers found western Ohio’s open tracts of warm season grasses and colorful summer wildflowers quite formidable. Dense seas of vegetation grew as tall as a person on horseback and the often wet conditions bred mosquitoes and other biting insects. Prairie was initially ignored for farming and development due to its lack of trees. The early thought was any land that didn’t support forest was infertile and not worth the time or effort to tame. Once that mindset was reversed and the prairie’s deep, rich black soil was bitten into by the steel plow, it wasn’t long before it had all but disappeared. Ohio Department of Natural Resources

Seismic events claw at the Doomsday glacier by rolling icebergs slamming into the fragile ice shelf.

Scenarios for iceberg calving at fast tidewater glaciers. Buoyancy-driven calving is likely to produce icebergs with small width-to-height ratios that will capsize against the terminus front. The generated iceberg-to-terminus contact force is responsible for the production of glacial earthquakes.

The most menacing glacier for coastal regions worldwide is the Thwaites glacier, aka the doomsday glacier, located in the active climate tipping point region of West Antarctica. Recently a new study found that Thwaites glacier’s marine extension’s underbelly is melting on all sides by warming ocean water. Researchers found that...
