Thursday’s Reads

David Biello summarizes two recent papers that conclude that within 40 years, we’ll add as much CO2 to the atmosphere as we’ve added since 1750 — a scenario that is likely to result in catastrophic climate change.

Tim O’Reilly’s and Sarah Milstein’s “The Twiiter Book” published in PowerPoint and previewed on slideshare.

The virology blog describes the three ways influenza virus’s can be transmitted: (1) by direct contact with infected individuals; (2) by contact with contaminated objects; and (3) by inhalation of virus-laden aerosols.

Green Technology in Education

without comments

Further and higher education establishments could save money and decrease CO2 emissions by introducing simple measures, according to a report issued today by the UK’s Joint Information Systems Committee (JISC). The report presents the findings of JISC’s Green Technology report. It outlines ways in which the intelligent use of technology can create savings of cost, energy or carbon output. The Green Technology Briefing Paper and Strategic Overview are available to read online now.

Carbon Cost of a Google Search

with one comment

Harvard physicist Alex Wissner-Gross claims that a typical Google search on a desktop computer produces about 7g CO2.

However, these figures were disputed by Google, who say in the official Google Blog that “one Google search is equivalent to about 0.2 grams of CO2″.

The complete story is on the BBC Website: ‘Carbon cost’ of Google revealed.

Jesus Leon Santos — grass roots ecology in Oaxaca

with one comment

I’m in Oaxaca, Mexico for a few days — enjoying the weather, the food and the people. It’s one the most beautiful places in the world, but very poor. Like many poor places,  people often deal with daily necessities at the expense of a sustainable environment. In the Mixteca Alto, a 6,000 square kilometer region in northern Oaxaca State, grazing, agriculture and forestry practices focused on short term needs have turned what were once lush forests into eroded fields.

Jesus Leon Santos took on this problem 20 years ago and this week he’ll be recognized as one of the winners of the Goldman Environmental Prize. I don’t know Leon Santos. I only came across his story because I’m in Oaxaca, but I find it instructional and inspirational. Several government programs had failed in the region. Leon Santos took a wholistic approach, involving people in reforestation, changing agricultural practices and even changing their eating habits to emphasize locally grown food. The efforts are paying off — there are over a dozen nurseries in different villages; trees are getting planted; ecologically sound drainage ditches are getting built and people are even shifting from raising goats to sheep to protect the trees.

I did get an offer from T-Mobile today — if I switch to paperless billing they will pay to have a tree planted. I was feeling slightly positive about “my tree” until I read what people can really do to affect their environment.

A much more complete description of what Leon Santos is doing is on the Goldman Prize Website.

Human Impact to the World’s Oceans

without comments

Google Earth view of upper US AtlanticFor a really “big picture” view of how we are impacting the our planet’s oceans, download the KML file from UC Santa Barbara’s National Center for Ecological Analysis and Synthesis: www.nceas.ucsb.edu/GlobalMarine

Load it into Google Earth and circle the planet. The data is the result of a study that concludes “over 40% of the world’s oceans are heavily affected by human activities and few if any areas remain untouched”. Our ecological footprint is not only large, it’s also very wet.
