Taking a Closer Look: The Last Ice Area

Posted on by

“I’m melting…I’m melting!!!” (Wicked Witch of the West, Wizard of Oz). This article takes a closer look on how the extreme melting of polar ice caps in the arctic have over-arching effects on several animal species, people and will have long term consequences for our environment.

It has become apparent that this cycle of melting is moving in a clear direction “an ice-free arctic.” There have been projections that the Arctic will experience its first ice-free winter in 2015; what will this mean for the animals and people who depend on this ice environment for survival?

The three major species that will be affected are polar bears, seals and walruses. Polar bears, who have a unique way of hunting seals and fish through gaps and holes in the ice need the sea ice for survival. Without it, polar bears have been driven to dire straits, swimming upwards of 500 miles to find icy hunting grounds, and others resorting to cannibalism for survival.

In terms of other species, it is predicted that the arctic habitat will overlap with that of the grizzly bears by 2040—creating additional threats for animals like walruses and seals. Forced into the Last Ice Area, this small number of remaining various species are clustered extremely close, raising competition levels and making it nearly impossible to find adequate food needed in order to carry on and reproduce.

For the people of the arctic, though warm temperatures might seem as a nice change to many of us, this actually is not the case. These warmer temperatures are in fact destroying their environment, livelihood and economies. With a warmer climate, as “ice melts, shore lines are becoming increasingly unstable, threatening entire towns with rapid erosion and rising sea levels.” Ice trails, important for crossing the ice in the past are disappearing, and as the arctic animals dwindle in population, so thus do the economies of these arctic towns, who depend on these species for the success of their market and general sustenance. As animal species are being forced to move closer and closer inward towards the coast due to the destruction of their icy habitats, this results in “more dangerous interactions between humans and animals.”

This article relates to many of the topics we have discussed in class this semester, showing the very real effects that global warming is having on our environment, and demonstrates what the future holds if we do not take global warming seriously and begin to take substantial action to reduce global emissions. If we do not, ice caps, polar bears and other arctic animals may soon be a thing of the past.

Polar Bears are Dying. EVERY COMMENT SAVES 1,000 POLAR BEAR CUBS!

Posted on by

Rapid loss of sea ice is leading a plummeting polar bear population. Why should we care?

1)    Polar Bears are at the top of the artic food chain.  If they become extinct then the food web will alter drastically.  Certain species, free of competition for food and/or no longer with a main predator, will flourish.  However, the environment, as a whole, will suffer.  Anthony Ives, a zoologist from the University of Wisconsin, has shown through experimentation that, in general, when a species becomes extinct, the community’s ability to tolerate environmental degradation lessens.

2)    So, the extinction of polar bears would prove bad for the overall artic biosphere.  Unfortunately, scientists estimate only 20,000 to 25,000 bears are currently living.  That number is expected to shrink to as low as 6,500 by 2050.

3)    And most importantly, polar bears are not only adorable but they manufacture 30% of the entire world’s supply of Coca-Cola.

Leading scientists hope that if the melting of sea ice is slowed significantly then the polar bear population will stabilize and even start to increase.  Unfortunately, slowing the melting of sea ice will require drastic measures.

Comment! What can be done to stop the melting of sea ice? How will dying polar bears affect the artic ecosystem? How much more efficient would polar bears be at manufacturing Coca-Cola products if they had opposable thumbs?

Milan’s Vertical Forest

Bosco Verticale

Milan, Italy is one of the most polluted cities in Europe. One radical idea to mitigate this problem is creating the “greenest” building possible. The Bosco Verticale (Vertical Forest) looks like something out of a futuristic movie and will easily be the greenest building in Milan upon completion. The architectural masterpiece was designed by Stefan Boeri Architects as part of their BioMilano initiative to convert about 60 abandoned farms around the city into a greenbelt of environmentally-friendly buildings. The Bosco Verticale will have a green façade on every side with dense forest systems planted on each floor. These forests will serve as a microclimate for the building filtering out the polluting dust particles from the city. The fully-functioning and living bio-canopy will also absorb CO2, moderate extreme temperatures, lower noise pollution, and oxygenate the air all without electricity. On top of all those perks, the building will provide (somewhat) natural aesthetic beauty that is so often absent from cityscapes, and lower the living or working costs for the occupants.

Architecture PlansProjects such as the Bosco Verticale provide hope for the polluted cities in the world and the green movement, especially if sufficient funding and support is provided. This short article is pertinent to our class discussions of the atmosphere and biosphere. More specifically, the building provides an excellent example of how plants regulate a variety of processes on Earth.

Discovery News – What Can You Discover?

Posted on by

After browsing through several not-so-interesting geography websites, I stumbled upon the Discovery News site.  Associated with The Discovery Channel, this site immediately caught my eye with its incredible pictures and interesting headlines.  The site is conveniently divided into seven categories ranging between physical geography topics (Earth, Space, and Animals), more cultural geography (Human and History), and just random super cool stories (Tech & Gadgets, Adventure, and Autos).  The website is truly engaging because of its numerous videos, photo galleries, and vast array of exciting science articles.  Below are some of my favorite stories so far:  

1)      This incredible series of photographs explores the phenomenon of visual color warnings in plants and animals.  The story explains that certain colors, patterns, and visual characteristics can communicate danger. 

 2)      This video talks about a recent eruption of an underwater volcano.  It relates to the discussions we had about the lithosphere in class and the difficulty of predicting when volcanoes will erupt.  Scientists were however, successfully able to give an 8-year time frame in which the volcano would erupt.  Scientists said this site was easier to predict because the crust was thinner and there was a huge supply of magma.  The video also gives a cool look at the underwater site.

3)      In relation to Matthew Sturm’s article about the changes in tree distribution as a result of climate change, this article discusses the movement of seaweed as a result of global warming.  Scientists believe that a profound amount of Australian seaweed is actually moving south in order to find cooler environments.

 4)      Last but not least, you can even take a look at the “Be as Manly as Bear Grylles Guide” because let’s be honest, who doesn’t love Bear Grylles?

“The Green Pope?” Religion and Science?

Posted on by

http://www.huffingtonpost.com/2011/11/27/pope-climate-change-conference-durban_n_1115016.html?ref=green

The pope and climate change? The church and the global climate? Religion and science? Are these all really coming together here??? You better believe it. Here we have an article talking about Pope Benedict XVI and his hopeful influence on the UN Climate Change Conference which starts today November 28, 2011! Delegates from nearly 200 countries are meeting to see what they can salvage from the wreckage of the Kyoto Protocol. That 1997 agreement aimed to cut greenhouse gas emissions from rich countries to an average of 5 percent below the levels they emitted in 1990.

 

A link is provided below to the actual conference website,

The Pope’s greatest concern seems to be the poor and the future, “I hope that all members of the international community can agree on a responsible, credible and supportive response to this worrisome and complex phenomenon, keeping in mind the needs of the poorest populations and of future generations,” the pope said.

This has not been posted for any reasons of specific religion. This is simply to look at a rarely seen connection between religion and science that I saw as interesting and worth reading. The Huffington Post  provides many more articles and even videos and picture slides that deal with climate change and news and are worthy of looking into as well, while on the website.

 

 

 

 

 

Hobbit-holes, not just for hobbits anymore

Posted on by

Geoff Weathersby

http://www.simondale.net/house/

If you’re like me then a small part of you wants to live in the Shire. There’s something very settling about how hobbits live. Tolkien made them very communal beings that didn’t waste much. Everything they took they gave back, and then some. Last year, I was fumbling around on the internet and happened to find a group of people who made real-life habitable hobbit holes. Needless to say, I was instantly intrigued.

They guy behind it all is a man named Simon Dale and he calls his creations “low-impact woodland homes.” For Simon, it’s all about environmental sustainability. He says that we need to start taking real action to cut off our dependence on fossil fuels and he says we can do it by relying on land as we did before the industrial revolution. This, he says, is the answer to the climate change problem. We need to establish self-reliant local networks that operate both mentally and physically closer to the land. He writes, “Climate change is a clear imperative to curtail our fossil fuel use.” He suggests we do this by planting edible perennial food, eating less meat, using wood for fuel by setting up lots for rotational wood harvesting, and learning basic handiwork skills. By doing so, we will create communities sustainable within themselves that take a whole lot less from nature and replace a whole lot more.

 To the left is a view from inside one of Simon’s low impact homes. It was made with a hammer, chainsaw and a chisle, cost 3,000 pounds, and took about 1500 man hours. It is 50 square meters in size, which is just under 550 square feet from our point of view. It is heated by a wood burning stove, gets water that flows down the hillside, is naturally lit by a skylight seen in the picture, and has solar panels that provide electricity. You can’t get much more sustainable than that.

I believe this has special relevancy for our class given our focus on the interplay between human life and our planet’s many systems. These low-impact homes, in a way, embody what I believe the take home message from our class to be. Earth is a closed system and we must plug into it. Burning fossil fuels, as well all know, is not a sustainable practice. As it is speculated that we have reached our oil peak, we all have to take a little responsibility in the quest for alternative energy. In the meantime, we need to look at how we’re currently living and examine how much we take that we don’t give back.  This is what drove Simon’s work and it needs to drive ours as well.

BBC Science and Environment

Posted on by

For years BBC news was the easiest and fastest source of world news for me. I usually use the Russian version of the website thought, which is slightly different. Recently, I discovered the Science and environment section on the BBC website.

EU climate commissioner Connie Hedegaard

This website is informative as a well as interactive. It has in the news story of the day. For example today  the main article on the page was Climate summit faces big emitters’ stalling tactics, it discussed the efforts of cutting GHG emissions by the nations. It showed that the debate about which countries should do what still continues even after the Kyoto protocol. According to the article developing countries will certainly target rich governments such as Japan, Canada and Russia over their refusal to commit to new emission cuts under the Kyoto Protocol, whose current targets expire at the end of next year. However, the article states that another main topic of the summit will be financial aid to the developing countries through Green Climate Fund, although it is not clear yet who exactly will provide the estimated funding of $10 billion dollars for the developing countries to reduce their GHG emissions. Developing countries say the public coffers of industrialized nations should be the main source, whereas industrialized world believes that private sector must be the primary source. At the end of the article the website provides links to previous articles related to the topic such as why did Copenhagen fail? I find that very useful, especially while starting doing research.

The main webpage of BBC science and environment has other unrelated stories below the main article, concerning different aspects of biosphere, hydrosphere, atmosphere and lithosphere. It also provides links to articles/ blogs by BBC experts on different topics. For example, I found one on marine reserves in Australia called Australia plans huge marine reserve in Coral Sea. The plan is to have fishing commercial and recreational allowed being only in some areas of the reserve, which at its closest point would start 60km (37 miles) from the coast and it extends out to 1,100km to protect the coral reefs.

The website also has great video and audio resources to keep the reader interested and save time. Videos and audios have related articles or text version below in case anyone was interested in keeping written record. Here is a video of an unusual formation beneath the ocean called Icicle of death.

Comment with your water footprint!!

Posted on by

By: Kyle Ragan

As we discussed in class earlier this year the United States has one of the highest water consumption rates in the world. Access to clean drinking water is already an issue to nearly one billion people around the world today. This number is only expected to grow as water may become one of the most fought over resources on earth. The issues around water use are both environmental and social. In class we mentioned the concept of virtual water. Virtual water takes into account your total water footprint for your daily life. While water usage may only take into account water that is consumed or used in your daily life. Virtual water also takes into account the water used to produce the food you eat and to transport this food to where you live. The first step to addressing the water problem facing the world is to better understand our own personal impact on global water.

The website H2o conserve provides tools for better understanding your own individual water usage. There is no perfect way to calculate an individual’s personal water footprint but H20 conserve provides a calculator that can estimate your individual water footprint. Use the calculator to calculate your water footprint. We can all look for ways that we can decrease our water consumption. The website also provides tips for ways that you can decrease your water usage.

We all have a role in helping the water crisis, take the first step and calculate your water usage and look up some tips about how to decrease your water footprint. Comment with your scores so that you can see how you compare with everyone else in the class.

 

 

 

What’s YOUR Ecological Footprint?

Posted on by

By Ruby Shumaker

Hey, everyone!

I’m sure you’ve all heard of the term “carbon footprint,” a measure of the amount of carbon emitted by an individual, an organization, or an activity. However, as I learned from a website from the Global Footprint Network, this footprint model is today often replaced by the Ecological Footprint as the major measure of humanity’s demand on nature.  The Global Footprint Network is a nonprofit organization established to enable a sustainable future on the Earth. The organization recognizes that in order to make this goal a reality, it is important to accurately measure human impact on the Earth to make more informed choices about our actions. For this reason, its mission is to accelerate the use of the Ecological Footprint, providing scientific data to drive large-scale, social change.

The site includes lots of great resources including information on the organization’s current programs and initiatives, links to each of its 90 partner organizations, a blog, and large sections detailing the components of an Ecological Footprint and the science behind it. When I first visited the site, I wanted to know the difference between an Ecological Footprint and a Carbon Footprint. So, I checked out the Carbon Footprint section of the site under the “Footprint Basics” tab. I found out that rather than measuring the amount of carbon emitted in tons, the Ecological Footprint translates the amount of carbon dioxide emitted into the amount of productive land and sea area required to sequester carbon dioxide emissions. This way, the Ecological Footprint shows us how our carbon emissions compare and interact with other elements of human demand, like our pressure on food sources and the amount of land we consume when we pave over it to build cities and roads. While the carbon component makes up 54% of humanity’s overall footprint and is the most rapidly growing component, the Ecological Footprint allows us to address the problem in a comprehensive way.

The Personal Footprint Quiz builds your environment as you answer questions about your lifestyle

There’s lots of information on the site about calculating Ecological Footprints for the world, for nations, for cities, and for businesses, but my favorite part of the site is the Personal Footprint Calculator. It’s a fun, interactive quiz (you even get to design an avatar!) that asks you questions about your lifestyle, such as how often you consume meat, how many miles you drive per week, and how often you recycle, to tell you how much land area it takes to support your lifestyle. At the end of the quiz, it lets you know how many Earth’s we’d need if everyone on the planet  lived your lifestyle (The Average American would require 5 Earths, I got 4), along with a breakdown of how much land you use in various areas of consumption. It also give you suggestions on how to reduce your Ecological Footprint. So, what’s your ecological footprint? Take the quiz and find out!
