At the UNFCCC Climate Change talks currently under way in Bonn the US Envoy Todd Stern has unequivocally announced the role the US will be playing in the time ahead.  It is an extraordinary transformation. The hopes raised by Obama still look strong. Some extracts follow. First, the opening remarks:

Telling porkies to Parliament

by Gareth March 24, 2009

The Emissions Trading Scheme Review committee has released the first batch of submissions it has received — those made by organisations and individuals who have already made their presentations to the committee. There are some heavy hitters in there: from New Zealand’s science and policy community there’s the Climate Change Centre (a joint venture between […]

Hit somebody! (The hockey song)

by Gareth September 2, 2008

Expect a renewed interest in the shape of hockey sticks, as a new paper in the Proceedings of National Academy Of Sciences (PNAS) by Michael Mann (et al) finds that the last decade was the warmest for at least 1,300 years. The BBC headlines the story “Climate “hockey stick” is revived”, which rather stretches the […]

Move on up

by Gareth August 18, 2008

Sometime in the next day or so, Hot Topic will be moving to a new server and getting a spiffy new look. I’ll do my best to ensure that there’s little or no break in service, but given that my techno-competence is strictly limited there may be a hiatus – with luck only brief. There’s […]

Celia of the seals

by Gareth August 13, 2008

It appears that my wish is someone’s command. Last month, blogging on the continuing break-up of the Wilkins ice shelf, I noted a reference to “seal hats” as data gathering devices and expressed a wish to see them. And here they are! Little devices glued to the heads of elephant seals that gather data as […]

The Arctic summer sea ice cover could be reduced by 2013 to “a few outcrops on islands near Greenland and Canada between mid-July and mid-September”, according to new research reported in The Observer [UK] today.

You’re the (NZ) first, the last, my everything

by Gareth August 6, 2008

So what’s happening to the Emissions Trading Scheme legislation? It seems to be stuck in the parliamentary back rooms, presumably because the government is struggling to put together enough votes to get the bill (or a version of it) passed before the election. No Right Turn has been keeping tabs on progress, and is of […]

Ice ice baby

by Gareth August 5, 2008

The fat lady’s not yet in the building, but her limo’s outside the theatre. There’s another five or six weeks of melting to go, but there’s more than just sea ice melting in the Arctic, and more than my few meagre wagers riding on how summer turns out ‘oop North. Here’s a compendium of interesting […]

Ballad of broken seas

by Gareth August 3, 2008

The Ministry for the Environment released an updated Coastal Hazards and Climate Change manual for local government last week, based on work done by NIWA. It incorporates the latest NZ thinking on where sea-levels are heading. If you’re planning to build something that has to last until the end of the century (and that covers […]
