Caspian Sea’s rapid decline threatens endangered seals, coastal communities and industry, study warns – Physics.org
Water levels in the Caspian Sea—the world’s largest landlocked water body—are getting lower, as hotter temperatures cause more water to evaporate than is flowing in. Even if global warming is limited to below 2°C, it is likely that the level of the Caspian Sea will decline by 5 to 10 m, but if temperatures rise further, water levels could drop by as much as 21 m by 2100..

They lost their coastal Malibu homes to fire. But should they rebuild along a rising sea? – the Los Angeles Times
“I think we suffer from what I call a short disaster memory. We want to get in there and build and rebuild as fast as we can,” said Gary Griggs, a UC Santa Cruz oceanographer and coastal geologist who wrote “California Catastrophes: The Natural Disaster History of the Golden State.” But the impermanence of coastal construction ”is not something most people are interested in hearing about.”…
