Seth Dixon's insight:
Pictured above is Lake Hillier, located on a small island south of Western Australia. Around the world there are many pink lakes; most of them can attribute their hue to their high salinity composition. Some algaes that thrive in salt water produce organic pigments with a reddish/pinkish coloration. This particular lake's coloration is a mystery.

Coastal and low-lying areas that would be permanently flooded in three levels of higher seas. This interactive feature is designed to answer a simple, yet profound set of questions. What areas (in over 20 cities around the U.S.) would be under water if the ocean levels rose 5 feet? 12 feet? 25 feet? The following set of maps show "coastal and low-lying areas that would be permanently flooded without engineered protection." Delete the scoop?

One of the nation’s most influential groups of engineers said it presented detailed warnings that a devastating storm surge in the region was all but inevitable and proposed ways to prepare.
MH: Hey, you know what? A bunch of engineers accurately predicted the kinds of damage the East Coast would face from a strong storm surge. Maybe we should give that science stuff a little consideration in our future plans in designing our cities. Delete the scoop?

Today, a country’s marine economic area is defined by its Exclusive Economic Zone (EEZ), a 200-nautical mile-wide (370 km) strip of sea along the country’s national coast line (hi-res image). This regulation, which was installed by the ‘UN Convention on the Law of the Sea’ in 1982, grants a state special rights to exploit natural (such as oil) and marine (for instance fish) resources, including scientific research and energy production (wind-parks, for example). Questions to ponder: how does this series of buffer zones around the Earth's land masses impact politics, the environment and local economies? Where might the EEZs be more important to the success of a country/territory than other regions?

Brace yourselves, East Coasters....
Thinking spatially, it's important to remember that not all places will be impacted equally. Even among coasts, not all spots would receive equal sea level rises when the ocean's systems are dynamic.

I have been to North Carolina and many of the other places mentioned in this article and have seen the damages of the water levels rising. One example of the water rising is a road in North Carolina going to Cape Hatteras that is now completely submerged underwater. There is now a make-shift bridge that runs over the underwater road.

I knew that the sea level was rising but I didn't know it was happening so quickly. I think that people living in the hot spot are should take this seriously. When I go to the beach there use to be a lot more beach between the road and ocean. but because of the rising sea level, the land between is becoming shorter and shorter.

The sea level is rising rapidly and I had no idea how serious it is and how much of an impact it's taking on the world. People living in the hot spot need to realize how serious of a problem this can turn into and that the sea level will have a big effect on the land as time goes by.

Indonesia has the largest share of the world's mangroves — coastal forests that have adapted to saltwater environments. They play important environmental and ecological roles.
Mangroves play a key role of acting as an ecological buffer in coastal region that provide the area with resilience against tsunamis, hurricanes and other forms of coastal flooding. Their role in carbon sequestration is also vital as energy emissions globally continue to rise. So let's jump scales: how are global issues locally important? How is the local deeply global? How can stakeholders at either scale find common ground with the other? Delete the scoop?

While city lights at night serve as a good proxy for population density, North Korea provides a dark exception.
Seth Dixon's insight:
This image is appears to be a regional inset of the classic Earth at Night composite image however this nighttime remote sensing image was taken from Sept. 2012. The Earth at Night image is typically used in classrooms to discuss what this actually means for human geography (Population density? Development? Consumption? Where? How come?). However, this particular portion of the global image focused on the Korean Peninsula highlights two other specific issues:

This cliché image of "North Korea in the dark" reinforces preconceived ideas about the "totalitarian" state and how terrible life must be without electricity. Well, one aspect of this political geography is the effect of US-backed sanctions against North Korea and the severe ecological and energy crisis under which it has struggled for the last two decades. Just as electricity is not simply a "natural" resource, neither is energe consumption nor shortage.

It also regurgitates troubling metaphors of darkness as backwardness.

However, this particular portion of the global image focused on the Korean Peninsula highlights two other specific issues: the impact of a totalitarian state can actually be seen from space as South Korea has a per captia income level 17 times higher than that of North Korea. the Exclusive Economic Zones (EEZs) can be seen in the Yellow Sea as fishing vessels form a line approximately 200 nautical miles off the coast of South Korea.Tags: economic, political, resources, water, sovereignty, coastal, territoriality, states, unit 4 political, remote sensing.

Fulgurites are the rocks that form when lightning strikes sand (there are other types as well) and it creates a hollow tube. Think of it as petrified lightning--super cool!

I have never heard of these before. I thought it was really interesting how they a made. It is confusing however how the article talks about lighting being able to create these almost every time it strikes then how come they are not more common?

If you want to see how to coax nature into producing these things while watching a rom-com, see "Sweet Home Alabama" w/Reese Witherspoon.

I find this article very interesting, I have never heard about or seen this in my life. I had no idea that these types of things could be formed from a lightning strike. The article is a little confusing however saying that these can happen all the time. Maybe it’s because I’ve never seen a lightning bolt directly hit the ground in front of me and see the reaction of the earth. I just find it hard to see as this being the first time I would come across something like this.

Competing territorial claims have led to maritime disputes off the coast of Asia. See a map of the islands at issue. This is an nice interactive map that allows the reader to explore current geopolitical conflicts that are about controlling islands. This is an good source to use when introducing Exclusive Economic Zones, which is often the key strategic importance of small, lightly populated islands.

Yesterday was Earth Day, a time set aside to increase awareness of the natural environment and the impact of our collective actions...
This is a gorgeous set of 39 images that are all view the Earth and captures images for above. These aerial photography and remote sensing images focus of a wide range of topics such as the cultural landscape, the environment, earth science, cultural ecology and urban systems. The photo above is of Mont-Saint-Michel, a tourist attraction and UNESCO world heritage site in northwestern France that is the world's premier example of the tombolo landform. Via M. Roman

Its interesting how patterns in this world repeat themselves, whether in nature or man-made objects. The pictures of the shanty town in Venezuela and the floating ice sheets in Germany are similar in their layers, overlapping, and repetitiveness.

"The threat of climate change is an increasingly important environmental issue for the globe. Because the economic questions involved have received relatively little attention, I have been writing a nontechnical book for people who would like to see how market-based approaches could be used to formulate policy on climate change. When I showed an early draft to colleagues, their response was that I had left out the arguments of skeptics about climate change, and I accordingly addressed this at length."
This is an excellent summary of the scientific basis for anthropogenic climate change as a scientific reality. It addresses the concerns of climate change skeptics, point by point and notes flaws in the logic, data or reasoning.

Flood Map shows the map of the area which could get flooded if the water level rises to a particular elevation.
Still in work in progress, but in essence this is a GIS layer showing which areas are at risk for flooding. You can set the elevation level to monitor where the threat is greatest and where it will infrequently occur as well. Delete the scoop?
