Beaches are facing off against a changing climate, and they’re losing ground. Literally. Waves, currents, storms and people all move the sand that make beaches, well, beaches. But a combination of rising sea levels, stronger coastal storms and coastal development means that sandy shorelines are increasingly disappearing, leaving the millions who live there facing major challenges in a warming world… “Sea level rise of one foot or a foot and a half per century is basically inundating and drowning the shoreline,” Norbert Psuty, professor of coastal geomorphology at Rutgers University, said… A common solution to beach erosion is beach nourishment, a process that pumps sand from dredging ships offshore to replace the lost sand on the beach. But this process is time consuming and costly and often needs to be repeated every few years to maintain the beach… “As a short term solution, it’s OK if you’re doing this to allow for changes to be made to reduce the infrastructure and to allow the system to return to quasi-natural state,” Psuty said.
Scientists Pore Over Warm West, Cold East Divide
From blooming flowers to twittering birds, the signs of spring are popping up and the miseries of winter are becoming a distant memory for many. But not for some climate scientists… The curiosity of a growing group of researchers has been piqued by t…
Cold Air Invasion Coming: What’s the Role of Warming?
Temperatures are set to drop to levels that are low even for the middle of winter across the eastern U.S. starting Thursday and again over the weekend as Arctic air makes repeated surges southward. Temperatures Sunday morning could be below freezing as far south as Florida… Rutgers University sea ice researcher Jennifer Francis was one of the first to suggest a link between the steady decline of Arctic sea ice caused by warming and the extreme twists and turns that the jet stream- the fast-moving river of air miles up in the atmosphere- can take northward and southward… “We’re learning that there are different mechanisms at play in different regions and seasons,” Francis said.
