Explore the world’s new coastlines if sea level rises 216 feet.
If all the ice in the world melted, we wouldn't have a post-apocalytic scenario like Kevin Costner's "waterworld," but it still would have an enormous global impact. This interactive feature highlights the locations of places that would be submerged in the most extreme example of hypothetical sea level changes. What would some of these changes be?

This is perfect for a unit on climate change and global warming. I would definitely recommend this in geography classes because it is a wake up call. Students can see the effects of climate change and draw their own conclusions about what they believe about this. I would use this with in coorelation with a video about global warming, or even use this as a webquest activity.

Aside from the mass devastation i think it would be pretty cool of all the ice melted. As the interactive map shows there would be in inland sea in australia which i can turn into the AUs great lakes. Also imagine the possiblility of being able to take a vacation to antartica and not having to dress for absurdly negative tempatures, all the undiscovered land and preservated fossils. It would be a interestling link to the past that only in the future we could experience.
"Two things that helped make this rainfall historic are breadth and duration. Colorado can get much higher rainfall rates for brief periods and over small areas."
Our thoughts are with our colleagues and friends in Colorado as they are dealing with the impact of this historic weather event. The geographic factors that contributed to this flooding are explained in this article from the University Corporation for Atmospheric Research (UCAR). Some are calling this a millennial flood, as it is well past the 100-year stage of flooding. You may view the areas impacted on an ESRI storymap. and in this NASA imagery.

The devastating flooding in Colorado has impacted so many. The rainfall Colorado has experienced makes it the most on record. The massive amounts of flooding and devestation in areas like Boulder are caused by the highly populated valley areas.
Almost seems like a perfect storm scenario. Large amouts of rain over a long perod of time over a large area. This combined with a late summer/early fall heat wave and tons of moisture in the air, with climate change all contributed to the disater in Colorado. They also believe the changes made by people to the physical geography over the last hundred years or somade have contributed to teh flooding in the area. Development can effect the way a place floods. Where there were once open fields and trees, there are now parking lots and houses which just can't absorb rainfall. Makes you ask the question, shouldn't there be more study of where we exapnd our cities and what effect this will have in case of a major rainfall, earthquake, blizzard, etc?
What was interesting about this particular deluge was how much rain fell and how it happened in such a short time. Meteroligist high wet density levels of vapor that rose to high altitutdes and was able to condense into water and help in a perfect combination of weather to create a powerfully dangerous flash flood.
The article recounts a former major colorodo flood that occured in 1978 and had killed over 150 people during a centenial celebration.
After this occurence warning signs were put up beside the roads to warn travelers of flash flood possiblities and to promote safety. These floods do not happen in Colorado often and are usually a surprise. They do not when the nextmajor flash flood may occur in the boulder region but they know through historical patterns that it will happen again.
This article stood out to me because I have friends that live in these areas and had to run for safety and move their cars to prevent damage in these same areas. The good thing is that the people that I know from this area are doing ok.
From the food we eat to the energy, transportation, and water we all need, a warmer world will bring big changes for everyone.
B Sinica: This article touches every aspect of geography from culture to climate [considering] how the growing population plays the biggest role in determining the future of life on Earth. People need to recognize the problems and potential future issues with global warming and the rapidly changing environment. Though not many issues can be prevented or even solved, the least we can do is try to lessen the severity of devastation and prolong the current conditions as much as possible before the world becomes too extreme to manage.
Some tangible ways that climate change can impact us in the future:

Climate change is going to affect how we live in the future. It will cause lack of food, energy sources, health risks, climate changes, drought etc. It is because of our growing population and the amount of people the world has to take care of for all of us to survive. We are also using too many of its resources too quickly. What could we do now to try to slow down the process of it happening?
For years, researchers have puzzled over why Viking descendents abandoned Greenland in the late 15th century.
As the climate began to cool the diet of the Greenland settlers changed dramatically. Originally their diets consisted of about 20-30% seafood, but as farming became nearly impossible on this increasingly marginal land, it jumped up to about 80%. The economic livelihood of the settlements was in danger and the solution lay in a cultural transition, but one that they didn't want to make. "They saw themselves as farmers and ranchers rather than fishermen and hunters...[and were] worried about the increasing loss of their Scandinavian identity." In essence they abandoned Greenland in part because they chose not abandon their Viking heritage to embrace a culture that would have be more like that of the Inuits. Cultural factors may have mattered more than economic limitations.

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.

An in-depth, multimedia look at climate change, its global impact, and efforts to combat it.
This guide on climate change from the Council on Foreign Relations (independent think tank) covers many of the geopolitical, economic and environmental issues that confront the Earth as global temperatures rise. Rather than produce a full length feature film, they have organized the this as an interactive video, allowing the user to get short (a couple of minutes) answer to specific questions about the science, foreign policy or economic ramifications of adapting to climate change.

This is an inflammatory article from an environmental organization that is speculative in nature (in other words, take it with a grain of salt). Yet, this type of thinking about the future and thought exercises is worthy of our investigation. What do you foresee in the future given the current conditions?

The drought footprint cover 63% of the contiguous states during the hottest month in American history. It's the hottest 12 month stretch (August 2011-July 2012) on record for the lower 48, making it the fourth consecutive month to set a new record (i.e. old record was July 2011-June 2012).The biggest difference from other hot months is the nighttime temperature have been exceptionally high. The most current drought monitor map can be found at the University of Nebraske website.
"Citing higher cheese prices, Colbert states it plainly:..."
Although in America today only about 2% of the workforce is involved in agriculture, crop cultivation is still tightly integrated within our economy affecting a much wider range of people and industries. According to the US Department of Agriculture we our currently experiencing one of the worst droughts in our nation’s history rivaling the Dust Bowl of the 1930’s. On a national scale, prices in gas, meat, dairy and other products that depend on crops will likely increase. However, since the U.S is a major producer of crops such as wheat and corn, the global economic consequences of this will be felt around the world. How will an increase in food prices effect people in countries were a quarter or more of their income goes towards groceries? How will a decreasing agricultural yield effect economic and political stability around the world? This is a humorous look at a very serious problem.

The Maldives is a small country in the Indian Ocean composed of 1,200 islands. Virtually every spot in this country is under 8 feet in elevation. Pictured above is the capital of Malé, which has the largest population (explore these islands on a variety of scales).
Questions to Ponder: What physical forces and processes account for the presence of these islands in the Ocean? In a geological time scale, what does the future hold for these islands. What would be the main economic assets of the Maldives? What would be the main economic and environmental concerns of this country?

The Maldives is an interesting country located in the Indian Ocean. It was not originally made up of the 1200 islands that it has now. Many of those islands are uninhabited and miniscule on a map. The country is dominated by tourism which is important for the country. What is also important to the country is its geographical future. Many of the islands might vanish in years to come because of rising sea levels. New islands can form as well as so many already have. The future of this country merely relies on what is happening underwater.
The photos we viewed in class have inspired me to add this to the list of places to visit over the course of my lifetime. The accomplishment of building up such a small piece of land on this scale is somewhat rare and often reserved for megacities on the larger continents.
Maldives might be hard to keep for many years due to the fact that it is in the middle of the ocean. Eventually overtime the waves would ruin whatever is on that land. It does not seem like a pratical place to live.
Did the Arctic region break a heat record?
The Siberian Times is reporting a record heatwave for towns such as Norilsk that are both North of the Artic Circle and built on permafrost. While on the global scale the climatic shifts are quite alarming, there are many in Siberia that see global warming as a mixed bag. In what some would have you believe is an unrelated news item, the North Pole is experiencing the formation of large meltwater ponds.

Global warming...no...Siberia is supposed to be a cold dark place...according to my Dad!
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.
Earth systems are inherently dynamic; however a change to system such as climate change can upset the system dramatically.

Energy conservation starts at home....
This interesting National Geographic article emphasizes how consumption patterns in the home are connected to some of the serious global issues that we currently face. This article becomes an exploration into how to go about creating a more environmentally sustainable home.
The best energy is the one we don´t consumpt!!
TED Talks As Vicki Arroyo says, it's time to prepare our homes and cities for our changing climate, with its increased risk of flooding, drought and uncertainty.
Our major cities are suceptible to environmental catastrophes for a whole host of reasons. Cities depend on a smooth of goods, money and services provided by infrastructure that we take for granted and assume will always work 24/7. Presented in the video are some ideas about how we should rethink our cities with a different ecological paradigm to protect our cities more in the future.

Governements around the world are slowly but surely creating new plans to ensure the safety of the people. They have already worked on evacuation plans and tranportation for getting people out but, they also need to think about where would people go and how will they adapt to their new enviornment. I'm glad that some places started working on plans to build houses, highways, and churches at a higher elevation, but other countries also need help figuring this stuff out. They need a solution to better secure homes and lives. Everyone needs to work together to prepare for climate change and natural disasters, especially those places where are most likely to hit.
UNAVCO, a non-profit university-governed consortium, facilitates geoscience research and education using geodesy.
"Researchers at the University of Colorado Boulder and the University Corporation for Atmospheric Research have been using what is typically considered an error in the GPS signal to measure snow depth around GPS receivers. A GPS receiver records both direct and reflected signals from a satellite. A reflected signal bounces off of whatever is around the GPS station before being recorded, and therefore can contain information about the ground surface close to the station.
Traditionally snow depth has been measured by hand. In other words, someone had to go out with a measuring stick to whatever location they were interested in. GPS snow depth measurements solve both of these problems: once a GPS unit is installed, it can function on its own throughout the winter, and will make a measurement every two hours, which is then averaged for a daily position, or in this case, snow depth."

Water scarcity's effect on food production means radical steps will be needed to feed population expected to reach 9bn by 2050...
This article represents a good example of neo-Malthusian ideas concerning population growth and food production. The recent drought and subsequent food shortage/spike in global food prices has renewed interest in these ideas.
From this article I can tell that the lack of water is getting more and more out of hand, affecting our food supply. It will not be a surprise for humans to become vegetarians as the lack of meat is apparent. Having a vegetarian diet is the only way for us human to have enough water for our own consumption. , I think it is not that bad to be a vegetarian, after all vegetarian leads a healthier lifestyle compared to people who always eat meat. Vegetables are good for our health after all. This makes me wonder, considering our lack of water and food supply, what will happen if people refuse to co-operate? And continues to waste resources, will we really be the cause of our own extinction?
It is increasingly clear that we already live in the era of human-induced climate change, with unprecedented weather and climate extremes.
I don't delight in sharing the bad news. So is this drought just a freak anomaly or a sign of a new normal?

NASA researchers are expressing concern about something they've never seen before: the melting of ice across nearly the entire surface of Greenland earlier this month.
Climate changes are afoot in the Arctic and the Greenland ice sheet. For more on the Arctic. In related news, Texas and Louisiana have introduced education standards that require educators to teach climate change denial as a valid scientific position. South Dakota and Utah passed resolutions denying climate change. Tennessee and Oklahoma also have introduced legislation to give climate change skeptics a place in the classroom.
