I examined my GHG footprint, and flying was what tipped my contribution well beyond sustainability. I still occasionally fly because all of our family are 3000+ miles away and I haven’t found an affordable alternative, but I have vowed to eliminate short-haul flights, unnecessary flights, and fly a lot less.
I am a paleoclimatologist working to understand climate variability over the last 1000 years, to put modern changes in context and to improve our ability to project future climate variability.
