Hello, everyone. I feel that there isn’t very much to say after Irena Lauzadiene’s post, which basically summarised the most important things we can do for the environment. However, I personally feel that the most important factors to affect the environment and our carbon dioxide emissions are to reduce our travelling costs and reduce how much meat we eat. After playing around a little bit with the carbon footpint calculator I realised that changing the amount of meat eaten drastically affects the amount of carbon dioxide you release into the atmosphere. Therefore, reducing our consumption of meat should be one of our main priorities when talking about carbon dioxide.
Transportation is obviously also an important factor; reducing the time we spend on airplanes should also be one of the things we prioritise when helping the environment.
Dear People of the ISCFC.
You will not save this planet by installing low-emission lights.
What is happening to the earth is a global problem (hence the name “Global warming”), and must be treated as such. What we need to do is not turn off the water when we brush our teeth, but rather put the resources we as humans possess to use in research concerning sustainable energy.
Even the time and effort put into creating this web page could instead have been used to help the environment.
Don’t take this the wrong way, but if we aim to save the environment by closing windows to conserve heat and expect that to make a significant difference, we’re doing it wrong. We’re deluding ourselves believing that we will make a change like that.
The most CO2 emissions in the world come from transports, and this is what we should focus on. If humans in power actually got off their butts and seriously invested into sustainable transport methods, such as geothermally-charged lithium batteries (yes, these exist. There have been motorcycles designed running solely on lithium-battery strength.)
I believe we’re fighting on the wrong axis. While showering in cold water and eating less meat certainly is cute, it will do little to improve the actual health of our planet. This planet needs brains that can figure out how to lessen our carbon emissions where we have the most, not self-gratifying students who believe they are changing anything.

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.
