The AGU Chapman Conference on water vapour and its role in climate has come to a close, and I have headed back to not so sunny London. In addition to getting scientists out of the lab, the meeting afforded great opportunities for normally independent communities to interact. Pupu platters and Longboard Ales led to a very interesting discussion about the meaning of terms such as mean global precipitation and temperature rise. Are statistics such as these preventing scientists from meaningfully communicating results about climate change? This of course comes back to old faithful argument “if the Earth is getting warmer, why did it snow last week?” Definitely something to think about when preparing press releases or giving interviews.
