Re: Tony Juniper CBE and others share their thoughts on LinkedIn

[John Nissen]

Hi Peter,

Somebody on LinkedIn has belatedly noticed an anti-geoengineering letter in the Guardian "Opinion Piece", written by Raymond Pierrehumbert, Julia Slingo, Michael Mann and Valerie Masson-Delmotte [1].  Is it worth calling them out? Or should they just be ignored?

Cheers, John
