As James wrote in the previous blog post, you're welcome to join us for our Special Session at the AAS meeting next Wednesday (7th January) at 12:30-14:00 in Room 4C-3. We'll be starting the new year with ideas and plans for addressing climate change issues in class and with the media.I work at the University of California, San Diego, and I'm taking the train up the Pacific coast to Seattle via LA, the Bay Area, Sacramento, and Portland. I'm traveling nearly 1500 miles (2400 km)--nearly the entire distance from the southern to northern border of the US. As I wrote on on my own blog, Amtrak trains expend 1,600 BTUs of energy per passenger per mile, while planes use 2,500 and cars use 3,900. Trains are much more energy efficient than planes, cars, and buses, and by not flying to Seattle, I'm saving tons of carbon dioxide emissions. This is just a start, but I am trying to view flying as a luxury or necessary evil that I will avoid and reduce when possible.
We encourage anyone who is interested in the Sustainability Committee to contact us and get involved. We will post resources on this website for teaching and discussing climate change with journalists.
It's important for astronomers to try to make observatories, telescopes, university department buildings, and computer centers as energy efficient as possible, but our largest environmental impact and carbon footprint comes from airplane flights to meetings, conferences, workshops, etc. According to a New York Times article, air travel emissions account for about five percent of global warming, and that fraction is projected to rise significantly as the volume of air travel is increasing much faster than gains in flight fuel efficiency.
It would help this situation to develop better resources and technologies for videoconferencing and remote observing, and these are areas where we should continue to make improvements. In addition, long-distance travel can be difficult for some people, such as for those with families and those in relatively remote locations, and videoconferencing and webcasts can make conferences more accessible to more people.
Nonetheless, long-distance travel is sometimes necessary, including for early-career scientists who need to advertise their work and network at conferences. I joined the Sustainability Committee in 2014, and one thing I am trying to do and trying to encourage others to do is to take more trains. In the US, long-distance trains can be very useful depending on where one wants to travel. They are not always the fastest mode of transportation, but they are comfortable, convenient, have nice views, and have wireless access if you need to work. And importantly, they save energy.
In any case, I'm excited to be part of the new and improved Sustainability Committee, and if you're interested, join us at the AAS and make an effort in 2015 to reduce your and your institution's carbon footprint.
After a brief respite and following excellent leadership by former chair Kartik Sheth, the Sustainability Committee has been reconstituted (see About Us for new membership). We will hold a Special Session at the Seattle AAS meeting in January:
12:30 - 2:00, Wed. Jan 7
We'll focus on two topics: 1. teaching climate change in Astro 101; and 2. communicating about climate change with the media and with climate skeptics/deniers. For part 2, we'll do a role-play exercise in which we stage a mock debate. Join us, and bring your best debate skills!
The Sustainability Committee has posted an article, Traveling Virtually, to the AAS web site with advice about how to work effectively in virtual environments, especially for meetings and observing, so that astronomers can reduce travel, make the best use of ever tighter funding, and help reduce astronomy's per capita carbon footprint.Please post additional ideas or experiences here!
Time to resuscitate this blog! The AAS Sustainability Committee, after a short sabbatical, has renewed its commitment to its mission, and with it, to maintaining this web space. One way we will do this is by significantly increasing the traffic on this blog, and by significantly, I mean at least one blog post per month (I know, crazy, huh?). So don't worry, still well within the safe range for your inbox, but somewhere above "non-existent".
And we'd love to have some help. So if you'd like to be a guest blogger, please add a comment or send a message to email@example.com to volunteer. Any topic related to our missionis welcome.
Please watch this space for more posts coming soon, and do get in touch if you have something to say. We look forward to hearing from YOU! Thanks!
We'll be posting announcements, minutes of our meetings, calls for input from the community and so on here, on the Sustainable AAS blog. Comments will always be open (but moderated) - please do add your voice!
