It’s on. Abbott dumps Paris, speaks science and ramps it up against Turnbull

by JoNova, July 4, 2018


Nine years ago the Australian Liberals were on the verge of splitting. Turnbull was about to give the Labor Party a free pass on the Emissions Trading Scheme and sell Australia out to the EU. Climategate broke (thank you FOIA) and the party rebelled and tossed out Turnbull. Now, after three elections where the people voted No to carbon taxes every time they could, we have an emissions trading scheme, a Renewable Energy Target,  and one of the most crippling Paris targets of any nation. This is despite our rapidly growing population, huge distances and massive resources and the failure of almost every other nation to even achieve their Paris goals.  We are The Global Patsy, obediently sacrificing competitive advantage, GDP, and lifestyle – all so Julie Bishop and Malcolm Turnbull get invited to the right parties. Economic carnage in a glorious quest to make the weather nicer.

Coal, a dying industry, just became Australia’s number one export (again)

by JoNova, July 2, 2018


Coal is a dying industry, but luckily for the Australian economy, the rest of the world is not as smart as The Australian Greens and Labor Party and they are still buying it.

Coal is set to regain its spot as the nation’s biggest export earner amid higher prices and surging demand from Asia, sparking fresh calls from the Turnbull government for Labor to end its “war on coal”.

The Department of Industry, Innovation and Science figures show total coal exports are forecast to reach $58.1 billion in 2018-19, overtaking iron ore ($57.7bn) for the first time in almost a decade. (…)

Can Universities Lawfully Bully Academics into Silence?

by Jennifer Marohasy, June 19, 2018


Dr Peter Ridd has taken James Cook University to court protesting his sacking for what he says is, primarily, speaking-out about the lack of quality assurance in Great Barrier Reef science.

Dr Ridd spoke out initially about there being no quality assurance of Great Barrier Reef science – science that is arguably misused to secure billions of dollars of tax-payer funding. When the University tried to stop Dr Ridd doing this, Dr Ridd spoke out against University management – making all the documentation public including on his new website.

Rise and fall of the Great Barrier Reef

by University of Sydney, May 28, 2018 in ScienceDaily


Over millennia, the reef has adapted to sudden changes in environment by migrating across the sea floor as the oceans rose and fell.

The study published today in Nature Geoscience, led by University of Sydney’s Associate Professor Jody Webster, is the first of its kind to reconstruct the evolution of the reef over the past 30 millennia in response to major, abrupt environmental change.

The 10-year, multinational effort has shown the reef is more resilient to major environmental changes such as sea-level rise and sea-temperature change than previously thought but also showed a high sensitivity to increased sediment input and poor water quality. (…)

Aussie PM: Coal to Hydrogen Plant Part of the Seamless Transition to Clean Energy

by Eric Worrall, April 13, 2018 in WUWT


h/t Geoff Sherrington – Coal is being rehabilitated as an essential component of the clean energy future.

Coal to hydrogen is not a new idea, the Water-gas shift reaction was discovered in 1780 by Italian Chemist Felice Fontana.

There are still some kinks to be worked out. The process to generate hydrogen from coal produces a monstrous amount of CO2 – far more CO2 per unit of useful energy than simply burning the coal would produce. But with hydrogen production, unlike hydrocarbon combustion, all the CO2 is produced in one place. This creates an opportunity for carbon sequestration, when technologies to sequester carbon on such an impressive scale are developed.

Mystery solved : Rain means satellite and surface temps are different. Climate models didn’t predict this…

by JoNova, March 18, 2018


A funny thing happens when you line up satellite and surface temperatures over Australia. A lot of the time they are very close, but some years the surface records from the Australian Bureau of Meteorology (BOM) are cooler by a full half a degree than the UAH satellite readings. Before anyone yells “adjustments”, this appears to be a real difference of instruments, but solving this mystery turns up a rather major flaw in climate models (…)

Australia overdoes carbon reduction by 294mt: could cool world by 0.0002C extra (maybe)

by JoNova, January 3, 2018


Other countries are failing to meet their targets, but we’re not only achieving them, we’re overdoing it. And this is despite our obvious handicaps: like that we have rapid population growth, are further from everywhere and anywhere* except for Antarctica, and we’re the largest coal exporter in the world;

Tropical Cyclone Trends

by Australian Gov. Bureau of Meteorology, September 2017


Tropical cyclones in the Australian region are influenced by a number of factors, and in particular variations in the El Niño – Southern Oscillation. In general, more tropical cyclones cross the coast during La Niña years, and fewer during El Niño years.

Analysis of historical tropical cyclone data has limitations due to a number of changes in observing practices and technology that have occurred over time. With new and improved meteorological satellites our ability to detect tropical cyclones has improved, as has our ability to differentiate tropical cyclones from other tropical weather systems such as monsoon depressions, which in the past may have been incorrectly named as tropical cyclones. A particularly important change occurred in the late 1970s when regular satellite images became first available from geostationary satellites above the Earth’s equator.

TEMPERATURE READINGS PLUNGE AFTER AUSTRALIA’S BUREAU OF METEOROLOGY ORDERS END TO ‘TAMPERING’

by  Graham Lloyd,   August 4, 2017 in Marc Morano, ClimateDepot


Recorded temperatures at the Bureau­ of Meteorology’s Thredbo Top automatic weather station have dropped below -10C in the past week, after action was taken to make the facility “fit for ­purpose”.

A record of the Thredbo Top station for 3am on Wednesday shows a temperature reading of -10.6C. This compares with the BoM’s monthly highlights for June and July, both showing a low of -9.6C.

The BoM said it had taken immed­iate action to replace the Thredbo station after concerns were raised that very low temperatures were not making it onto the official record.

Prof Peter Ridd: the Great Barrier Reef recovers, our science institutions are failing us, science needs to be checked

by Alan Jones, interviews peter Ridd, July 28,  2017 in JoNova


Corals have a little thermometer built in them, when you take a core of them from many years ago we know what the temperature of the water was back when Captain Cook sailed up the coast, it was actually about the same temperature then. It was colder 100 years ago, but it has recovered from that. The temperatures on the reef are not even significantly warmer than average on a hundred year timescale.

Corals that bleach in one year will be less susceptible to bleaching in following years

On Sunday, Goulburn got colder than the BOM thought was possible (and a raw data record was “adjusted”)

by JoNova, July 2017


The BOM got caught this week auto-adjusting cold extremes to be less cold. Lance Pidgeon of the unofficial BOM audit team noticed that the thermometer at Goulburn airport recorded – 10.4°C at 6.17am on Sunday morning, but the official BOM climate records said it was -10.0°C. (What’s the point of that decimal place?) Either way this was a new record for Goulburn in July. (The previous  coldest ever July morning was -9.1°C. The oldest day in Goulburn was in August 1994 when it reached -10.9°C).
