Here’s a superb high resolution supercomputer visualisation from NASA’s Goddard Space Flight Center of the flows of CO2 in the atmosphere around the planet. Apart from being beautiful to look at, it shows the major sources of CO2 emissions in the northern hemisphere, and the seasonal change in CO2 levels as the northern hemisphere summer plant growth makes the planet “breathe in”. All the major features of the flow of weather around the planet are shown in great detail. The visualisation was produced by a new very high resolution global climate model called GEOS-5. The NASA press release explains:
…the visualisation is part of a simulation called a “Nature Run.” The Nature Run ingests real data on atmospheric conditions and the emission of greenhouse gases and both natural and man-made particulates. The model is then is left to run on its own and simulate the natural behaviour of the Earth’s atmosphere. This Nature Run simulates May 2005 to June 2007.
It is a very high resolution model:
The resolution of the model is approximately 64 times greater than that of typical global climate models. Most other models used for long-term, high-resolution climate simulations resolve climate variables such as temperatures, pressures, and winds on a horizontal grid consisting of boxes about 50 km wide. The Nature Run resolves these features on a horizontal grid consisting of boxes only 7 km wide.
With high resolution comes the need for a lot of computing power:
The Nature Run simulation was run on the NASA Center for Climate Simulation’s Discover supercomputer cluster at Goddard Space Flight Center. The simulation produced nearly four petabytes (million billion bytes) of data and required 75 days of dedicated computation to complete.

The Kickstarter campaign to get climate documentary Thin Ice shown on public TV in the USA is closing in on its target. At the time of writing, the total pledged stands at NZ$21,199 — just over 75% of the way to the $27,500 needed with 4 days to go. The film’s producer, professor Peter Barrett, is pleased with the progress:
We are enormously grateful to our 156 supporters thus far. It’s proving to be a challenging journey, but it will be worth it if we can get Thin Ice tailored for American Public TV for the most influential people in the world on this issue.
For an idea of just how good Thin Ice is, have a look at the video above — scientists talking about why they do science. Dave Harwood defines science, Nancy Bertler and Ros Rickaby talk about what turned them on to it, Wally Broecker says what’s important for him, Liz Sikes explains why she enjoys it, and Ray Pierrehumbert gives some reasons for trusting the scientific process.
If have any spare cash for a good cause, get over to Kickstarter and make a pledge. And spread the word: there’s not far to go, but there are only 4 days left to hit the target. Let’s make it happen!
The National Business Review — New Zealand’s biggest-selling business weekly — provides a happy media home for climate deniers of all stripes. Columnists like former ACT Party leader Rodney Hide and right wing spin doctor Matthew Hooton are given free rein to rant and rave about climate issues, but occasionally editor Nevil Gibson offers its august platform to others so that they can spout fatuous piffle. Last week’s issue featured an opinion column by Chris de Freitas, in which he waxes lyrical about his recent paper on the NZ temperature record — the shonky one that claims to find warming to be only one third of what real experts calculate.
The NBR hides most of its material behind a paywall, so I can’t link directly to the text — but the less scrupulous chaps at the NZ Climate “Science” Coalition are happy to host a pdf lifted from the NBR site.
As you might expect, de Freitas doesn’t restrict himself to narrow concepts of truth and factual accuracy. He mentions the cranks’ court case…
The High Court ruled against the trust and ordered it to repay court costs.
… but neglects to point out that the trust has since failed to pay those costs. It has of course been put into receivership, thus allowing the trustees to escape the $90,000-worth of financial consequences of losing their crackpot case.
de Freitas also misrepresents the membership of the trust.

Minister knows of water woes, but public information tap is turned off
Finance Minister Bill English has been told something about fresh water — but the public isn’t allowed to know what it is. Last month, Ministry for the Environment officials were forced to admit they were wrong to say that the quality of our waterways is “stable or improving”.
Deal or no deal — can China and the US deliver?
It’s been called an historic agreement — a game changer in the battle to combat climate change. But can China and the US fulfil the promises in their announcement of plans to cut carbon emissions?
Does this climate deal let China do nothing for 16 years?
“As I read the agreement it requires the Chinese to do nothing at all for 16 years while these carbon emissions regulations are creating havoc in my state and around the country.” — US Republican Senate leader Mitch McConnell, November 12, 2014.

Today’s news that the US and China have agreed a long term policy to reduce carbon emissions is being hailed as a “game-changer” in international climate negotiations. China has agreed to cap its emissions in 2030 — the first time it has committed to anything more than a reduction in the carbon intensity of its emissions, while the US will aim to cut emissions by 26-28% on 2005 levels by 2025, up from its current target of 17% by 2020. [BBC, Guardian, Climate Progress.] Meanwhile, NZ’s third term National government is being warned by its own civil servants that its current emissions policy settings commit the country to substantial emissions increases over the same time frame.
With the world’s two largest emitters — between them they account for 45% of total emissions — agreeing to work together for the first time, prospects for a global deal in Paris next year look brighter than before. However, the cuts on the table do not look like enough to keep the planet on a trajectory to 2 degrees of warming or less. Associate professor Peter Christoff of the University of Melbourne explains (via The Conversation):
These commitments will frame the levels of ambition required of other states at Paris next year. Climate modellers will no doubt now be rushing to determine what these new commitments, if delivered successfully, will mean for combating global warming.
The US and Chinese cuts, significant though they are, will not be enough to limit the total increase in the atmospheric carbon dioxide unless other states engage in truly radical reductions.
In other words, global emissions are likely to continue to grow, probably until 2030, which will make it impossible to hold global warming below the world’s agreed limit of 2ºC above pre-industrial levels.
In New Zealand the briefings for incoming ministers in the new government — same as the old lot, in climate relevant ministries — have been remarkably blunt in their assessment of the task the country faces. [now read on…]
Canadian Tom Rand is an enthusiastic promoter of the clean technologies which are fully capable of saving us from the worst ravages of climate change. He’s also an investor in the field – a capitalist, he happily acknowledges. And importantly for his readers he’s a lively and thoughtful writer with a knack for striking observation. Waking the Frog: Solutions for our Climate Change Paralysis [Amazon] is partly an attempt to understand why we have stepped back from what looked in the early 1990s like a promising start to rein in greenhouse gas emissions. It is also an affirmation that we have the means to move rapidly away from fossil fuels if we have the will.
Rand hopes that the fact that he is a capitalist operating within the system he critiques will lend credibility to his criticisms.
