Rising seas will cut off many properties before theyโ€™re flooded

Climate change produces lots of risks that are difficult to predict. While it will make some eventsโ€”heatwaves, droughts, extreme storms, etc.โ€”more probable, all of those events depend heavily on year-to-year variation in the weather. So, while the odds may go up, it's impossible to know when one of these events will strike a given location.

In contrast, sea level rise seems far simpler. While there's still uncertainty about just how quickly ocean levels will rise, other aspects seem pretty predictable. Given a predicted rate of sea level rise, it's easy to tell when a site will start ending up underwater. And that sort of analysis has been done for various regions.

But having a property above water won't be much good if flooding nearby means you can't get to a hospital or grocery store when you need to or lose access to electricity or other services. It's entirely possible for rising seas to leave a property high, dry, but uninhabitable as rising seas cut connections to essential services. A group of researchers has analyzed the risk of isolation driven by sea level rise, and shows it's a major contributor to the future risks the US faces.

Major earthquake devastates areas of Southern Turkey and Northern Syria

A major earthquake and a series of strong aftershocks shook Southern Turkey and other parts of the Middle East on Monday. The most powerful of these registered 7.8 magnitude, placing it among the five most powerful earthquakes recorded during the 21st century in the world.

This first earthquake, at 4:17 am local time in Turkey (Sunday evening in the United States), was followed later in the day by another powerful temblor hundreds of kilometers away, at magnitude 7.5, as well as additional aftershocks. These earthquakes appeared to be occurring along the East Anatolian Fault, which divides the Eurasian tectonic plate to the north from the Anatolian plate to the south.

Earthquakes of this magnitude produce violent shaking of the ground and landslides and can level buildings. They are terrifying and deadly events for people living nearby. Early death counts, as of Monday, had already exceeded 1,600 people, The New York Times reports.
