Stuffed birds and hot years (Merry Christmas)

The fourth LP I bought (after Sgt Pepper and The Monkees first two albums — this was 1967/8, and I’d just acquired a record player that could handle discs larger than singles) was a Stax sampler called This Is Soul. It triggered a life-long love of that Memphis soul sound, and in particular the voice of Otis Redding. His version of White Christmas is a thing of joy. Play it today, and think not of the fact that this year is likely to set new records for hottest year on many of the global temperature series.

Nick Cave’s take on Christmas is (characteristically) a little gloomier than most, and perhaps more appropriate.

Things down here are fragmented

In fact they’ve exploded all over the room

I think everything’s a little off-center, babe

I do dear, I do

So, dear reader, allow me (and all the contributors to Hot Topic) to wish you the very merriest of whatever season it may be that you are currently celebrating. In the Waipara Valley it looks like it’s going to be a long hot day. A turkey is truffled and soon to be cooked, there is too much good wine to drink ((Considering the supplies laid in for the next week, and my intention to have a dry January, my liver is going to take a hammering. Do not expect much in the way of posts here.)), and Rosie the beagle is looking forward to a break in her post-harvest diet. Nadolig llawen.

PS: If confronted by a climate-denying family member over the holidays, here’s some advice on how to approach them, from The Conversation via the NZ Herald.

Carbon News 15/12/14: smoke and mirrors

English goes silent on carbon deficit costs


The Government is refusing to discuss what impact a 2030 carbon deficit will have on the economy – despite warnings from Treasury. Finance Minister Bill English has confirmed to Carbon News that Treasury is predicting carbon prices of between $10 and $165 a tonne between 2021 and 2030, but he has not answered questions on what that will cost New Zealand.

Climate expert: It’s all smoke and mirrors, Mr Groser


New Zealand is using smoke and mirrors to meet its 2020 emissions reduction target, when it could get there by using clean heating and transport technologies, says one of our leading scientists. Climate Change Minister Tim Groser told Radio New Zealand National this morning that while New Zealand faced some big hurdles in cutting emissions, the country was on target to meet its pledge to cut emissions to 5 per cent below 1990 levels by 2020.

Climate talks off on the rocky road to Paris


A deal struck in Lima between 196 nations today leaves open the possibility of saving the planet from dangerous overheating. But its critics say the prospects of success are now slim.

Fossil fuel probe under way as NZ goes exploring


New Zealand is expanding oil and gas exploration at the same time as Britain probes the likely cost of stranded fossil-fuel assets. Continue reading “Carbon News 15/12/14: smoke and mirrors”

Is earth’s temperature about to soar? (No pause, no hiatus, only warming)

This is a guest post by the statistician who blogs as Tamino, cross-posted from his Open Mind blog with his permission. It’s important reading…

A recent blog post on RealClimate by Stefan Rahmstorf shows that when it comes to recent claims of a “pause” or “hiatus,” or even a slowdown in global surface temperature, there just isn’t any reliable evidence to back up those claims.

Yet for years one of the favourite claims of those who deny the danger of global warming has been “No global warming since [insert start time here] !!!” They base the statement on the observed data of earth’s surface temperature or its atmospheric temperature. Then they claim that such a “pause” or “hiatus” in temperature increase disproves, in one fell swoop, everything about man-made climate change.

They seem a bit worried lately because it is very likely that the data from NOAA (National Oceanic and Atmospheric Administration) will record this year as the hottest on record; we won’t know, of course, until 2014 is complete. A single year, even if the hottest on record, has only a little to do with the validity of such claims, but a lot to do with how hard it is to sell the idea. Perhaps they dread the prospect that if the most recent year is the hottest on record — in any data set — it will put a damper on their claims of a “pause” in global warming. If they can’t claim that any more, it deprives them of one of their most persuasive talking points (whether true or not). Still the claims persist; they’ve even begun preparing to ward off genuine skepticism spurred by the hottest year on record.

I seem to be one of very few who has said all along, repeatedly and consistently, that I’m not convinced there has been what is sometimes called a “pause” or “hiatus,” or even a slowdown in the warming trend of global temperature — let alone in global warming.

Carbon News 8/12/14: NZ’s multi-billion carbon blowout

We’re facing a $3b carbon crisis … and it could be worse

New Zealand has a $3 billion carbon headache looming – and Treasury says that’s the conservative estimate. Carbon emissions in the period 2021 to 2030 could cost the country as much as $52 billion. Official briefings to the incoming Government acknowledge that the costs of meeting emissions reductions targets after 2020 were likely to rise significantly because “our emissions are forecast to increase and carbon prices are likely to be higher”.

The country needs a carbon budget, says pressure group

A climate change lobby group is calling for a national carbon budget and legally binding emissions reduction targets. The Sustainability Council’s paper comes as it releases figures showing New Zealand is facing a carbon liability of between $3 billion and $52 billion by 2030. Drawing on Government documents and its own work, the research and advocacy trust paints a picture of a country running a creative carbon accounting process, in which carbon liabilities have been shunted off to a time when carbon prices are predicted to be much higher.

Groser has a cunning plan (but he won’t say what it is)

Climate Change Minister Tim Groser says New Zealand will “push the envelope” on post-2020 emissions reductions. But he still won’t say what that means. New Zealand has to announce its 2021-2030 emissions reduction target before the negotiations for a new international climate treaty in Paris late next year. Groser, who is now in Lima for UN climate talks, told TV’s The Nation at the weekend that the target didn’t have to be settled until the middle of next year.

Ocean heat drives surge to global warming record

It’s official, even though it won’t be conclusive for a few months yet: if present trends continue, 2014 will be one of the hottest years on record − and quite possibly the hottest of them all. Continue reading “Carbon News 8/12/14: NZ’s multi-billion carbon blowout”

NZ: pushing the world to go beyond 2 degrees

head-in-the-sandNew Zealand is coming under increasing scrutiny in Lima, not least because it’s our turn to be reviewed by the UNFCCC process.

Early next week our representatives will have to defend our position and our lack of action to 190 governments in our first “multilateral assessment.”

Already, there have been some tough questions, coming especially from the EU and China. New Zealand’s answered them, but will have to more to defend itself than these carefully fudged answers.

Our negotiators have been trying to promote our position around the meeting, including a botched attempt in a science discussion yesterday, when they were interrupted halfway through a blatant PR presentation. They were told to get back to the issue at hand (science, not promotion of a country’s so-called “efforts”), after a number of governments objected to our highjacking the agenda.
