These tools just give ammunition to the climate sceptic crowd and annoy everyone else. I wish the media wouldn't give them attention for stunts like this.
They seem to take the 'ignore to avoid encouraging them' approach with streakers at football games etc, I think they should apply the same approach here. Or if the actual protest might be noteworthy (like vandalising the painting) then acknowledge it happened, maybe state their group affiliation and move on. Certainly don't invite them for interviews on a talkshow FFS.
Just perpetuates one of the problems with our media where sensible experts get sidelined by people with extreme views on either end of an issues who get interviewed as though they represent the two (yes, only two) 'sides' of an issue.
Rather than getting some rational discussion of the likely progression and impact of climate change and options to reduce it, we end up with mindless pronouncements and rage filled rants.
