There's good news and there's bad news. Two new studies focusing on ice melt in Antarctica and Greenland have revised down the worst-case scenario for the amount of sea level rise the world could see by 2100, but say the overall climate impacts of melt water entering the oceans could be devastating.
"The sea-level estimates maybe aren't as bad as we thought, but the climate predictions are worse," lead author of one of the studies and Antarctic Research Center of the University of Victoria, Wellington climate scientist Nick Golledge told National Geographic.
Weather and climate aren't the same. It's one thing for people who spend little or no time learning about global warming to confuse the two, but when those we elect to represent us don't know the difference, we're in trouble.
For a U.S. president to tweet about what he referred to as "Global Waming" because parts of the country are experiencing severe winter conditions displays a profound ignorance that would be embarrassing for an ordinary citizen, let alone the leader of a world power.
Greenland is melting about four times faster than it was in 2003, a new study published Monday in the Proceedings of the National Academy of Sciences found, a discovery with frightening implications for the pace and extent of future sea level rise.
"We're going to see faster and faster sea level rise for the foreseeable future," study lead author and Ohio State University geodynamics professor Dr. Michael Bevis said in a press release. "Once you hit that tipping point, the only question is: How severe does it get?"

In the latest troubling study regarding how the climate crisis is affecting the world's iciest regions, a new report by the Scottish Association for Marine Science (SAMS) found that the second-largest ice sheet in the world is currently melting even in winter.
The study follows a report released earlier this month showing that Greenland's ice melt rate is currently faster than it's been in about 7,000 years. The island's 650,000 cubic miles of ice is melting 50 percent faster than it did in pre-industrial times.
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.
