For decades, south Louisiana residents have watched coastal landmarks disappear as erosion worsened and the Gulf of Mexico marched steadily inward.

Climate change is dramatically altering the Swiss Alps, where hundreds of bodies of water are being created by melting glaciers. Though the lakes can attract tourists and even generate electricity, local residents also fear catastrophic tidal waves.

A new study using data from a pair of gravity-measuring NASA satellites finds that large parts of the arid Middle East region lost freshwater reserves rapidly during the past decade.
"[This] data show an alarming rate of decrease in total water storage in the Tigris and Euphrates river basins, which currently have the second fastest rate of groundwater storage loss on Earth, after India," said Jay Famiglietti, principal investigator of the study and a hydrologist and professor at UC Irvine. "The rate was especially striking after the 2007 drought. Meanwhile, demand for freshwater continues to rise, and the region does not coordinate its water management because of different interpretations of international laws."

New rules announced last week to allow interceptions of ships in the South China Sea are raising concerns in the region, and in Washington, that simmering disputes with Southeast Asian countries over the waters will escalate.
According to this new announcement, Chinese ships would be allowed to search and repel foreign ships if they were engaged in illegal activities (but that is open to interpretation) if the ships were within the 12-nautical-mile zone surrounding islands that China claims. This makes the disputed territorial claims of China all the more at the center of this geopolitical maneuverings. Much of the South China Sea would then be under Chinese control if this announcement becomes the new reality.
Questions to Ponder: Why is China making this announcement? Is China within their rights to make this declaration? Who might oppose this?
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.

Experts say Hurricane Sandy is wider and stronger than Hurricane Irene, which caused more than $15 billion in damage in 2011, and could rival the worst East Coast storm on record.
This is a quick visual comparison of remote sensing images that lets you slide to compare the superimposed images.

National Weather Service Advanced Hydrologic Prediction Service...
When the Pawtuxet River flooded in Rhode Island, I was watching this site to get a sense of how bad the flooding was and to put it in historic context (the National Weather Service has links to live data at many locations). This particular station in NYC at the Battery is important to keep an eye on with Hurricane Sandy because if the strom surge is over 10 feet, the subway system could flood and the issues confronting New York would be devastating. As meterologist Andy Lesage noted, "During Irene it got to 9.5ft, 8-12 inches shy of flooding the subway system so if the Battery gets to something like 10.25+ ft, it will indicate massive damage to the cities' infrastructure." For more see, the Weather Underground and Jeff Masters' analysis.

For years, China claimed to hold an estimated 50000 rivers within its borders. Now, more than half of them have abruptly vanished.

As climate change alters rainfall patterns and river flows, tensions are bound to rise between states and countries that share rivers that cross their borders. In the Rio Grande Basin of the American Southwest, that future inevitability has arrived.

There will soon be 7 billion people on the planet. Find out why you shouldn’t panic—at least, not yet.
This whole year, National Geographic has been producing materials on the impacts of a growing global population (including this popular and powerful video). Now that the year has (almost) concluded, all of these resources are archived in here. These resources are designed to answers some of our Earth's most critical questions: Are there too many people on the planet? What influences women to have fewer children? How will we cope with our changing climate? Are we in 'the Age of Man?' Can we feed the 7 billion of us? Are cities the cure for our growing pains? What happens when our oceans become acidic? Is there enough for everyone?

This interactive map of coastal Massachusetts and Rhode Island shows some basic flooding data including: 1) where are the flood warnings (essential the entire coastline), 2) how high the storm surge is, and 3) how high the waves are.
