Leah and I watched the An Inconvenient Truth on 4th of July with a couple of friends. It was both nothing new and revelation to me. Nothing
new because all the facts Al Gore presents in the movie, I've
previously read in New Scientist
over the course of perhaps a decade. Revelation because having Al Gore
summarised all the facts and evidences in a coherent argument brings a
much greater impact than each individual items.
As for how carbon neutral we are, using the Carbon Calculator,
Leah and I are both emitting less than the national average (9900 for
me, 13000 for Leah, US national average is 15000 pound/year). This is
still much higher than I thought we are emitting, taking into account
of us not owning a car and having a very small electricity bills. The
majority of our emission is from the trans-Atlantic flights that we
take to UK every year. I guess we just have to cut down our European
visit in the name of saving the planet!
