BBC Science and Environment

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.

What’s YOUR Ecological Footprint?

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!

Nasa’s Climatological Website

Well, hello there gang!

If you ever happen to be looking for information or topics on large scale climate issues then look no further than Nasa’s climatological website. As soon as you visit the site’s homepage you see a wealth of information on a variety of climate issues. How about arctic sea ice levels? Yep, they have that. Carbon Dioxide information? Of course. Sea levels and global temperatures? You bet. How about land ice, do they do land ice? Most definitely.

There are also tabs on the homepage related to key indicators like carbon dioxide concentration, evidence like sea level rising, causes like greenhouse gases, effects like weather intensification, and uncertainties like the effects of solar output on Earth.  The tabs for each of these climatological phenomena are easily accessible in the event that any skeptics visit the site at any point. If you ever need to make an argument for the existence of climate change, this website is a fantastic place to start your research for such an arguement.

Perhaps the most persuasive and fascinating aspect of Nasa’s climate website is the wide selection they have of satellite imagery obtained by one of their three Earth orbiting satellites (called “Grace,” “AIRS,” and “Jason-1”) like this:

Of the images on the website, Nasa also has a wide array of photographs taken from people in the field like this:

Whether you’re doing research in order to debate against a climate change skeptic, for school, or for your own personal interest, Nasa’s climate website ought to be your first stop!

Science Daily

Hey everyone! It took me a while to decide on a geography related website to post in the blog. Ironically, the site I finally chose, sciencedaily.com, has been a favorite repository of random scientific facts and knowledge for a while now for both myself and my father (it is my dad’s homepage, so every time I use dad’s computer I am greeted with the latest interesting scientific news. My dad does not qualify as a scientist (he sells beer for a living), but every time he finds something cool on Science Daily he emails it to me. Like literally every time haha). Anyway, when you log on to Science Daily you immediately see the days top headlines in the scientific world. For example, today’s top stories include titles such as Ancient Stars Shed Light On the Milky Way, Whiskers: Milestone in Evolution of Mammals,  The Strange Rubbing Boulders of the Atacama, and Bats Can Rapidly Change Ear Shapes. Everytime that I log on I tend to unconsciously dedicate 15 to 20 minutes of my time sifting through novel discoveries.

Today’s most interesting topic was about the unique boulders of the Atacama Desert, which ties in nicely with out recent study of the lithosphere and weathering processes. The large , smooth boulders found in the driest desert on earth were dislodged from hills surrounding the various basins located in the desert. Due to frequent seismic activity and earthquakes, the boulders, which have been in the basin for nearly 2 million years, rub against each other many times over the course of geologic time which creates their characteristic smooth sides. This process of weathering is extremely rare, and can only be found in areas of extremely low rainfall and high seismic activity, two conditions characteristic of the Atacama Desert. A picture of the boulders taken from the article is shown below.

The website contains a lot of other cool features that allow you to find articles regarding specific topics. These topics vary temendously and include a myriad of topics associated with the atmosphere, hydrosphere, lithosphere and biosphere. For instance, one of today’s articles, titled Evidence of Ancient Lake in California’s Eel River Emerges, credits a past catastrophic landslide with the creation of a lake that affected, and still today affects, the gene’s of the region’s steelhead trout. It is a fascinating study that connects changes in the lithosphere and hydrosphere dictating changes in the biosphere. This article could be found under 3 different tabs (Plants & Animals, Earth & Climate, Fossils & Ruins), further proving the interconnectedness of the science of physical geography. Geography itself is a topic tagged in many of the posts, including an article about the spatial distribution of long-term carbon storage in the Ganges Basin. This website is really interesting, and like I said, if you spend a couple of minutes searching through the varying articles you are bound to learn something really interesting!

 

 

 

 

 

THE MOST INTERESTING BLOG EVER-PLEASE COMMENT!

About Project Noah: http://www.projectnoah.org/about

I came across the website through an advertisement on the National Geographic Website. Clicking on the link soon lead me to an interesting project that four NYU graduates have created. Entitled “Project Noah”, the experiment attempts to build a fun, location-based database mapping out wild-life intercations all around the world. The way Project Noah works is that anywhere at anytime, if you come across an organism, you take a picture of it, post it on the website, and attribute a location to where you spotted it. Oftentimes, members do not know the “official” names of the organisms that they take pictures of- but that is where the social networking aspect of Project Noah comes in. On the website, you can post and comment on the pictures by writing the name of the organism or general feelings toward the picture.

Another aspect of Project Noah is that it conveys the vast biodiversity around the world. With over 120,000 participants, and over millions of pictures uploaded, Project Noah serves as a catalog for speicies diversity and dispersion. Members can also participate in “missions”, which link all the classified organism pictures into a central location such as the National Saguaro Park. This helps scientists count and identify the certain species in the Park.

Project noah’s most notable feature is that it can be downloaded as an app, so pictures and categroizations can be uploaded easily and at any time. I see this whole project as a way to encourage people to reconnect with nature, documenting local wildlife, and creating “citizen-scientists”.

Banff Wildlife Crossings Project

This summer I visited Banff National Park in Alberta, Canada and we spent a lot of time driving on the Trans-Canada Highway. All along the TCH in Banff National Park, there are wildlife overpasses and underpasses that allow wildlife to safely cross the road without risking collision with vehicles on the road. I took a picture of one of the two overpasses currently in the park (it’s a little blurry). Having learned about habitat fragmentation and the importance of corridors in other classes, I decided to look more into this specific case.

The purpose of wildlife underpasses and overpasses is not only to protect the animals from the immediate risk of road mortality caused by park infrastructure, but also to help maintain a stable and diverse wildlife population. Because the Trans-Canada Highway is so large and heavily used, it has become a huge barrier for wildlife, which restricts their movement and habitat area, and eventually leads to a less diverse population because they are confined to a smaller habitat patch, and eventually can lead to extinction. Road mortality can also have an effect on a species’ population in a shorter amount of time (1-2 generations) than edge effects caused by the road. The project created is called The Banff Wildlife Crossings Project and was started in 1996.

In Banff National Park, they have created various measures of wildlife crossing structures in order to attempt to solve this problem. There are two wildlife overpasses that span 50-m wide over the highway. They monitored the effects of these wildlife over and underpasses for five years. From this they discovered that they have reduced all road-kill by 80%. As to determine the effect of the over and underpasses on reducing habitat fragmentation, a longer-term study is needed. However, overall the project has been a success.

 

Chesapeake Bay Shows Signs of Improving Health

Link: http://www.ens-newswire.com/ens/nov2011/2011-11-03-093.html

According to research being performed by scientists at Johns Hopkins University and the University of Maryland Center for Environmental Science, the efforts to clean up the Chesapeake Bay are proving successful.  Water samples compared to those over the last several decades show that the nation’s largest estuary is getting healthier in a sense.

This has come about as a result of reduction of the flow of fertilizers, waste, and other pollutants, which has in turn reduced the overall size of the oxygen-starved dead zones (uninhabitable areas for plants and animals) in the body of water.  Rebecca Murphy, who is part of the Department of Geography and Environmental Engineering at Johns Hopkins, believes that there is a direct correlation between the two occurrences, which seems a good sign for the future of the Chesapeake Bay and other vital water bodies.

The effort to clean up the bay really took hold in the 1980s with the federal Chesapeake Bay Program, which focused on restoring the previous condition of the water.  While this past year did not present the  best data regarding shrinking volume of dead zones, the overall trend in recent years has been positive in that these oxygen deprived areas have been decreasing.  Some scientists were concerned as there have been reports of early summer jumps in dead zone activity, but this has been shown to be a result of climate forces such as heavy rains, wind, salinity, and the sea level of the water.  If not for the efforts to decrease the flow of the contaminants into the Chesapeake Bay, the prevalence of the oxygen starved zones would surely have been worse.

IN SUMMARY: While overall climate change has been having negative effects on the Chesapeake Bay, localized monitoring and pollutant reduction has lessened the issues. Hooray for a positive (or at least less negative) development!

 

Economic Prosperity at the Environment’s Expense: Different Resource, Same Outcome?

Two Rivers: The Chance to Export Power Divides Southeast Asia

By Jeff Smith (National Geographic)- 10/25/11

River picture: A person wades in the Irrawaddy River. http://news.nationalgeographic.com/news/energy/2011/10/111026-mekong-irrawaddy-hydropower-dams/

Despite being two separate waterways, the Mekong and Irrawaddy Rivers are crucial to both the human and animal population that currently rely on it to survive. As China continues to grow industrially at its current rate, on a continent that is“energy hungry,” Laos and Burma are in the midst of determining the economic benefits and environmental downfalls of constructing hydropower dams on the rivers.

Hydropower dams have potentially devastating consequences for migratory fish and wetland ecology along the rivers. They redistribute water with the mindset that producing energy is the main goal. Generally speaking, dry season river flows tend to increase while the wet season peak flows tend to decrease in order to maintain the proper levels of energy production. While this would seemingly lead to a more hands on approach to flood control that is not the main priority of these dams, and thus, not a guarantee.

The risks for these projects are straightforward: besides from the obvious environmental disruption, it threatens the ecology and animal habitats it supports.  Additionally, it threatens to disrupt the livelihoods of fishermen and farmers alike who rely on its flow to support  their families and are the economic engine for small villages along the river. Contrastingly, a hydropower dam will generate potentially billions of dollars by exporting the megawatts of energy it produces to countries such as China and other neighboring countries where energy is in high demand.

Intriguingly, Laos has seemingly accepted the risks and has moved forward with construction of a dam on the Mekong River whereas in Burma, the government has ceased work on the construction of the dam in the Irrawaddy River. The Irrawaddy has significant spiritual significance for much of the Burmese population who were surprised by the government’s democratic acceptance of the public’s outcry.  Although many activist groups in Laos are fighting intensely to have the government overturn its decision to move forward with the project it is likely that both countries are still in limbo. It will be interesting to see what the near future holds.

 

Hopefully, we can get a conversation started about the following environmental ethics debate.

*As the world is demanding more and more energy and there is an increasing global push for alternative  forms of energy (rather than fossil fuel), is risking the ecology and habitats of these rivers a worthwhile investment environmentally speaking? Clearly the economic incentive is there, but as the fossil fuels of the world continue to decrease while simultaneously affecting our climate, is hydroelectric power a reasonable, if not, crucial alternative in the coming years?

 

What’s Your Pollution Scorecard?

Coal-fired power plantDespite the success of national legislation like the Clean Air Act, the Clean Water Act, and the Federal Insecticide, Fungicide, and Rodenticide Act, pollutants still enter the environment at alarming rates. We can easily identify obvious sources of pollution—sulfur dioxide is bound to be coming out of a coal-fired power plant’s smokestacks—yet often less-obvious sources go unnoticed.

When pollution from any of these sources enters the environment, the substance likely enters either the air, local ground or surface water, or the soil; some of these substances may remain in these locations for many years. These chemicals have obvious effects: human and environmental health suffer in a variety of ways.

Nevertheless, the landscape of the region and the physical distance from a polluter means that some locations will experience only minimal levels of a pollutant. Wind and other weather patterns could transport a pollutant away from region and toward another; a city-dweller living next door to a factory will inhale many more toxic chemicals than will a rural farmer living kilometers away.

Luckily (or not, depending on your perspective) there is an online tool to determine which polluters exist in your locality. By visiting Scorecard, you can input your home or current zip code and get a list of polluters in your locality, the location of those polluters, how much pollutant they emit, and which pollutants are most prevalent where you live. For instance, I learned a company was emitting lead-based compounds from what I thought was an office building adjacent to the suburban neighborhood where I grew up! You can also see if any Superfund sites exist near you, determine the cleanliness of your local water, and learn what percentage of homes in your area have risk for hazardous levels of lead.

How many polluters are in your locality? Are you surprised at what you find out? Let us know in the comments!

THE ART OF GLOBAL WARMING coal + ice photography exhibition open at three shadows

 Chongqing, China picture taken from: http://sites.asiasociety.org/coalandice/photographers/ , picture credit information taken from: http://www.prixpictet.com/2009/view/605/5211

An art exhibition open Sept. 24 – Nov. 28 at the renowned Three Shadows Photography Art Centre in Beijing features the works of 30 photographers hailing from across the globe including the United States, the United Kingdom, China, Norway, Russia, Italy, Canada, Malaysia and Germany.

These artists’ photographs tell a story from the base of the coalmine to the peaks of the Himalayas.

Photographs, including those taken by American photographer and filmmaker David Breashears, who co-directed the first IMAX film shot on Mount Everest, demonstrate how the use of coal emits greenhouse gases that are warming high-altitude climates like the Himalayas, where rapidly melting glaciers are affecting river currents, which in turn play havoc with the lives of downstream residents.

The photographs span an “arc” of phases showing how greenhouse gases resulting from coal use go up into the atmosphere causing the glaciers to melt, thus affecting the hydrologic cycle. The exhibition also includes time-lapse photos that show the changing landscape.

The goal of the exhibition is to promote environmental awareness as well as tell a beautiful, yet haunting visual story.

For more information, and to watch a behind the scenes video with commentary from the curators see the gallery’s Web site: http://sites.asiasociety.org/coalandice/
