If you are interested in sea level rise news, you have a busy week. First we learn from a Nature Climate Change publication that the Greenland ice sheet is already gone. Then earlier today two studies published in Environmental Research … Continue reading →
Nearly four million Americans, occupying a combined area larger than the state of Maryland, find themselves at risk of severe flooding as sea levels rise in the coming century, new research suggests.
Figure 4 - 2nd of two Environmental Research Letters SLR publications. Sea level rise storm surge flooding risk along US coast. For the ensemble average estimate of relative SLR at each gauge, projected return periods, by 2050, for floods currently qualifying as 100 yr events.
Our most important source for knowledge about past life is the fossil record. But how exact is it in telling us about the history of life? According to a new study in Science the evolution of marine life over the … Continue reading →
Researchers of Utrecht University say the Greenland ice sheet may be more stable now than during the Eemian, the previous interglacial period, which lasted from 130,000-114,000 years BP. It turns out back then Arctic insolation was bigger – although still … Continue reading →
Last week we learned 5 percent of the Eemian sea level rise was thermal expansion of the oceans. Today we learn the slightly higher temperatures led Greenland to ‘only’ add an extra 1.6-2.2m. Do we fail to spot the Antarctic … Continue reading →
Sounds like there’s new food to calibrate our oceans’ sea level sensitivity. In red the image shows inundations around the Gulf of Mexico under Eemian sea levels. That’s ‘bye bye Houston, New Orleans, Miami.’ Two days ago we looked at … Continue reading →
In March we learned ice sheet formation is two-sided. On Sunday, sipping coffee whilst reading the latest Nature Geoscience, we learned the same might go for ice sheet melting. If so, melting would likely accelerate over this century and sea … Continue reading →
Comparing previous interglacial periods, like the Eemian, to the present geological epoch, the Holocene, shows slight average temperature rises are strongly magnified around the poles. Even under the 450 Scenario 21st century sea level rise could reach multiple meters. “Current … Continue reading →
