Ice Sheets in Greenland, Antarctica Could Reach Catastrophic 'Tipping Points' if We Don't Limit Warming

Scientists just gave us another terrifying reason to limit global warming to 1.5 degrees Celsius above pre-industrial levels: If temperatures push much beyond that point, both Greenland and Antarctica's ice sheets could reach a point where nothing can stop them from melting.

An international team of researchers published this chilling finding in Nature Climate Change Monday. The researchers set out to study how the ice sheets would fare in a warming world, and the results were urgent.

Video: Freedom to Breathe Tour Bus Visits Communities Across the Country Working on Climate Solutions

By Owen Agnew

Wildfires, sea level rise, air pollution, asthma—you don't have to go far to find communities living with climate change impacts. But there are also climate solutions everywhere you look. This summer, the Freedom to Breathe Tour visited communities across the country that are working to reduce carbon emissions and make their communities healthier and more resilient.

Hurricanes, Water Wars Threaten New High-End Oyster Industry on Gulf Coast

By Daniel R. Petrolia and William C. Walton

For Cainnon Gregg, 2018 started out as a great year. After leaving his job as an installation artist to become a full-time oyster farmer in Wakulla County, Florida in 2017, Gregg began raising small oysters in baskets or bags suspended in the shallow, productive coastal waters of Apalachicola Bay.

Raising oysters "off-bottom" this way takes a lot of time and money, but has a big potential payoff. They are destined for the high-end raw bar market, where offerings are denoted by specific appellations, like "Salty Birds" (Cainnon's oysters), "Navy Coves" (from Alabama) and "Murder Points" (also from Alabama), and can retail for twice the price of oysters harvested from traditional on-bottom reefs.

Iceberg 5x the Size of Manhattan Breaks Off Pine Island Glacier

The Pine Island Glacier, the fastest-retreating glacier in Antarctica, lost another massive chunk of ice earlier this week.

A 115-square-mile section calved off the ice shelf on Oct. 29. That's roughly the five times the size of Manhattan.

Melting Glaciers Dramatically Alter Canada's Yukon

Glaciers in Canada's Yukon territory are melting at an alarming pace, causing bodies of water to dry up and whipping up dust storms in the region, CBC News reported.

Researchers have determined that the rapidly retreating Kaskawulsh Glacier in the Yukon's St. Elias Mountain region cannot compensate for the volume it is losing now each year.

70% of Venice Flooded by Highest Tide in at Least a Decade

The worst flooding in at least a decade swamped Venice Monday as an exceptionally high tide covered around 70 percent of the iconic island city, the Huffington Post reported.

Venice is the Mediterranean World Heritage Site currently most at risk from flooding due to sea level rise, according to a recent study, and the city even has elevated sidewalks ready in case of high tides, but Monday's waters rose higher than the emergency sidewalks.
