A few tips on flying green

Time/Asia had a short article on how to fly green a couple of weeks ago. This is something that is constantly on my mind given the large amount of travel I do for my job as a scientist speaking at conferences and teaching workshops mostly in the Northern Hemisphere. From New Zealand you know you are doing some damage going on these flights.. The article makes a couple of points about flying direct and so forth. But it seems to neglect the most important thing to do if you have to fly: it is actually not that expensive to completely offset your carbon dioxide emissions using the services of companies like MyClimate. Carbon neutral travel is a reality. Do it :-)
