Seth Dixon's curator insight, February 5, 2013 3:05 PM

This set of maps and articles help to explain why sea level rise is such an issue for many major metropolitan areas.  In coastal cities with substantial economic development, much of the current coastal areas where once underwater until landfill projects filled in the bay.  During storm surges (or if and when sea levels rise) these will be the first places to flood.

James Hobson's curator insight, September 10, 2014 3:18 PM

Here's somehing to "Swett" over for those who live along the coast:

"Coastal cities are now living in what Brian Swett calls a “post-Sandy environment.” In this new reality, there is no more denying the specter of sea-level rise or punting on plans to prepare for it. And there is no more need to talk of climate change in abstract predictions and science-speak. We now know exactly what it could look like."

Keep in mind that as globalization expands, urbanizaion does as well, putting more and more people at this type of risk.

What Does Your City Look Like From Space?

" Who isn’t moved by images of the Earth at night?

 

In the contrast it shows between nature and settlement—in the civilizational network it reveals—it gestures at the mystery of human society. These composites are referenced in movies and in art and, especially, in data visualizations.

 

And I had assumed unthinkingly that the images above and below, last updated by NASA in 2012, were about as much as existed. A new database shows how much more there is. "

Volcanic islands can seem to appear out of nowhere, emerging from the ocean like breaching monsters of the deep. Below, Mika McKinnon explains how these odd geological formations are born, how they evolve, and how they eventually vanish back beneath the waves.

Matthew Richmond's curator insight, December 2, 2015 3:30 PM

Re-scooped from Professor Dixon, pretty cool story on the formation of islands in the south Pacific. A couple of them look like the island visible from the beach in Rincon, Puerto Rico where I stayed. The island is one giant rock so nobody lives there and it's a naval base for the U.S. military. This, however, is a different situation when you realize that not only do people live here, but kind of a lot of people live here.

Matt Ramsdell's curator insight, December 14, 2015 9:00 PM

What causes the death and the caldera in a volcano? One thing that happens in a deceased volcano is the center of the volcano starts to either erode or the inside finally caves in. Once this happen a caldera takes shape and the ocean starts to take over. As the waves eat away at the shores it will eventually create a island that is shaped like a "U". After this happens that island will someday retreat back into the ocean and someday form a barrier reef.

Adam Deneault's curator insight, December 14, 2015 10:52 PM

Based on general knowledge, I know that the taller a volcano is, the younger it is and the shorter it is, the older it is. The reason they start to get short is from erosion. Hot spots in the Earth's crust make small islands from molten rock. Young islands can be very dangerous, because if they are inhabited, they have the possibility of erupting, whereas an old island does not since the volcano is lnactice and eroding. Over time the inactive volcano will crumble and a caldera will take shape and after even more time, that caldera will slip under the ocean and become a reef.

C'est un outil unique de suivi et d'analyse de l'évolution de l'occupation des sols franciliens. Réalisé à partir de photos aériennes de toute la région Île-de-France, le Mos distingue les espaces agricoles, naturels, forestiers mais aussi les espaces urbains (habitat, infrastructures, équipements, activités économiques, etc.) selon une classification en 81 postes.
