Gareth Renowden Jan 15, 2011

All of the major global temperature series — surface and satellite — report that 2010 is tied for first place as the warmest year in the long term record.

Another local climate change denial meme - Open Parachute

Ken Perrott Dec 24, 2010

I commented in Painted into a corner? that the release of NIWA’s report of the recalculation of New Zealand’s 7-station  long term  temperature series had called the local climate change deniers’ bluff. It was time for them to apologise, withdraw their … Continue reading → … Read More

NIWA’s new NZ temperature series: plus ça change… - Hot Topic

Gareth Renowden Dec 16, 2010

How to be a denier: lesson #1 (shrivel and die) - Hot Topic

Gareth Renowden Nov 17, 2010

One of Hot Topic’s favourite sceptics is NZ C”S”C member Roger Dewhurst, best known for turning up from time to time to unload links to the denier meme du jour (and for his carefully cultivated grumpy old man persona). Yesterday morning he sent me a link to this “interesting” document prepared by Dr David Evans, [...] … Read More

Keep right on to the end of the road - Hot Topic

When one spends a good deal of time following what scientists working on climate change are saying, it’s hard to understand how the community at large and politicians in particular can appear so unaffected by the prospect ahead if we don’t radically reduce our greenhouse gas emissions. The only conclusion is that they haven’t yet [...] … Read More
