In light of some of the discussion of how habitat destruction and biodiversity reduction has lead to emergence of zoonoses, this article profiles Nathan Wolfe, a biologist who studies infections that have dire consequences for human beings. His work is in trying to prevent viral transmission to the human host.

Arctic Sea Ice Volume: PIOMAS, Prediction, and the Perils of Extrapolation
Filed under: Arctic and Antarctic Climate modelling Climate Science — group @ 11 April 2012
Guest Commentary by Axel Schweiger, Ron Lindsay, and Cecilia Bitz
We have just passed the annual maximum in Arctic sea ice extent which always occurs sometime in March. Within a month we will reach the annual maximum in Arctic sea ice volume. After that, the sea ice will begin its course towards its annual minimum of both extent and volume in mid-September. This marks the beginning of the ritual of the annual sea ice watch that includes predictions of the extent and rank of this year’s sea ice minimum, as well as discussion about the timing of its eventual demise. One of the inputs into that discussion is the “PIOMAS” ice-ocean model output of ice volume – and in particular, some high-profile extrapolations. This is worth looking at in some detail.
Welcome to new teachers and students joining us from Bolivia, Brazil, China, Cote d’Ivoire, Croatia, Egypt, Ghana, France, Slovenia, Spain, Sweden, the United States, and Venezuela. Participating in the ISCFC seems like a wonderful way to celebrate Earth Day, April 22nd!
Dear ISCFC teachers-
We now have our first April 2012 pin on the world map representing the student footprints and statistics from Ian Heathcote’s Environmental Science class at Escuela Campo Alegre in Caracas, Venezuela!
Which schools across the world will be next?
My name is Ann Smart. I teach Environmental Science in New Orleans, LA, USA, and am VERY NEW to this program. I just heard about it last week and got registered as soon as I heard about it. My students will begin calculating their footprints on Monday. I think they will be in for a very rude awakening. They think they are doing well if they place a piece of paper into the recycle box in the classroom. I can’t wait for them to do the calculations and to see what students in other countries are doing for the Earth. Thanks for this program
