The Sydney Morning Herald reveals – Sydney area an ‘urban heat island’ vulnerable to extreme temperatures 14 Jan 2016 – It is welcome that such basic facts can be spoken about.
Research by the BoM 15 years ago found measurable urban effects in small Victorian centres Hamilton, Camperdown-Cobden, Colac. The BoM paper can be downloaded as a 216KB pdf-
HT Anthony Watts – In the Sydney Morning Herald and other papers in the Fairfax stable if you Google the headline – Distorted universities need a reality check – it is repeated in The Age too.
Time to revist the progress of solar cycle 24 –
SIDC Brussels have produced a Version 2 series of sunspot numbers that looks very close to SWO NOAA.
SWO have a prediction out to end 2019 using the Version 1 RI numbers.
Does anybody know of any predictions for the timing of the next minima?
This research by Chinese scientists in Hefei is reported in Nature – Partially oxidized atomic cobalt layers for carbon dioxide electroreduction to liquid fuel
and Popular Mechanics – Breakthrough Material Is a Better Way To Turn CO2 Into Clean-Burning Fuel.
Could a process such as this be a basis for making CCS (Carbon Capture & Storage) more worthwhile?
ABC news today WA bushfire tears through Yarloop; homes destroyed

747 SuperTanker can carry 76 metric tons being refurbished in the USA.
The link is here Modulation of Ice Ages via Precession and Dust-Albedo Feedbacks.
His earlier paper was discussed – Albedo regulation of Ice Ages, with no CO2 feedbacks. And on a related subject I posted – Some climate sanity after Paris COP21 blabfest – drawing attention to The book “The Chilling Stars” by Henrik Svensmark & Nigel Calder sums up 12,000 years of Holocene cosmic & solar driven “climate change” in the North Atlantic. Ralph tells me he is in touch with Henrik Svensmark.
We present here a simple and novel proposal for the modulation and rhythm of ice ages and interglacials during the late Pleistocene. While the standard Milankovitch-precession theory fails to explain the long intervals between interglacials, these can be accounted for by a novel forcing and feedback system involving CO2, dust and albedo. During the glacial period, the high albedo of the northern ice sheets drives down global temperatures and CO2 concentrations, despite subsequent precessional forcing maxima. Over the following millennia CO2 is sequestered in the oceans and atmospheric concentrations eventually reach a critical minima of about 200 ppm, which causes a die-back of temperate and boreal forests and grasslands, especially at high altitude. The ensuing soil erosion generates dust storms, resulting in increased dust deposition and lower albedo on the northern ice sheets. As northern hemisphere insolation increases during the next Milankovitch cycle, the dust-laden ice-sheets absorb considerably more insolation and undergo rapid melting, which forces the climate into an interglacial period. The proposed mechanism is simple, robust, and comprehensive in its scope, and its key elements are well supported by empirical evidence.
The ABC have this article claiming – Rooftop solar producing more energy than WA’s biggest turbine – Curtin University sustainability professor Peter Newman said – “It’s nearly 500 megawatts and it’s growing rapidly,..” Yet when I check NemWatch for WA I can only ever find a little over ~250MW for WA small solar. Is this because about half the output is used in the homes of the owners of these rooftop solar systems?
And of course the article seems to forget that these solar systems only work in the sunny hours – they make no electricity at night while the coal fired generators chug away 24/7. I wonder to what extent the WA grid can keep on accommodating increasing solar and wind power yet remain stable. I also wonder what is the cumulative cost of all the small scale solar subsidies paid out by the various Australian Governments.
I like the way the Greens leader Dr Richard Di Natale says the policy “lacks evidence”. Careful Richard – if you apply that guideline the Greens may soon have no policy left.
North Korea has been busily developing nuclear and missile capabilities for a few decades now. All the evidence points to a growing potential for North Korea to eventually be able to mate a nuclear weapon with a viable missile or other delivery system. This Timeline from The Arms Control Association makes for sobering reading.
