Australia to dump renewable energy subsidies, quit trying to control climate with windmills and solar?

Wow. Australia may dump the RET — the renewable energy target — and stop trying to use our national grid to make global weather nicer for our great grandchildren? This would be legendary.

“Lowering prices will be more important than lowering emissions”

Don’t break out the Moët yet. Note two caveats.

1. The Daily Telegraph “understands” this to be true. Not definitively announced. Not passed through cabinet. Is this just testing the water to see how hot it is?

2. Australia will still try to meet our pointless Paris agreement some other way. Sure.

Will those big complex winner-picking, market fiddling schemes go?

Daily Telegraph

RENEWABLE energy subsidies and emission-reduction targets will be replaced with a focus on lowering electricity prices under the Morrison government.

New Energy Minister Angus Taylor said the federal energy policy has been “a mess” and says the fact prices have soared while blackouts persist means something has “gone terribly wrong”

The complex schemes Mr Taylor refers to are understood to be the Large-scale Renewable Energy Target (LRET), which subsidises the development of renewable energy.

The Daily Telegraph understands emission-reduction [...]

Silence to save the Planet! Stop debates, chuck hissy-fits, and hope no one notices.

The alarmist case is so strong they will Not Discuss It.

Right now, the world is going to hell and expert scientists need to convince the doubting masses that they face a dire threat. They have rock solid evidence. Do they:

Patiently answer questions with graphs and data. or Shout “fire” and ask for 89 trillion dollars, then tar those who disagree as pedophile-nazi-loving-idiots, throw a tanty and refuse to answer questions.

Obviously, expert scientists make mistakes.

Michael Bastasch | The Daily Caller

Climate Alarmists refuse to debate skeptics: “We are no longer willing to lend our credibility to debates over whether or not climate change is real. It is real. We need to act now or the consequences will be catastrophic,” reads the letter signed by 60 self-described “campaigners.”

Beware — balanced articles can kill people, cause floods! Run, Run…

From the letter:

In the interests of “balance”, the media often feels the need to include those who outright deny the reality of human-triggered climate change.

Balance implies equal weight. But this then creates a false equivalence between an overwhelming scientific consensus and a lobby, heavily funded by vested interests, that exists simply [...]

Climate change brings snow to Europe in summer

Good news. Children who don’t know what snow is can now ski in summer.

Heavy Summer Snowfall in European Alps – Austria, Italy, Germany & Switzerland Receive Up To 40cm

Matt Wiseman, Mountainwatch

Heavy snow fell above 1500 metres across the European Alps this weekend with a number of destinations reporting over 40cm of the fluffy white stuff.

While it is still summer in Europe, temperatures dropped over 15 degrees and dipped into the negatives in less than 24hrs

European heatwave comes to an abrupt end

Debbie White, Mail Online

There’s been a dramatic plunge in temperature across parts of Europe where searing heat has suddenly given way to heavy snowfall of up to 40cm – despite it still being summer.

About 25cm of snow was dumped on Germany‘s highest peak, the Zugspitze, where temperatures reached a decidedly chilly 19.4F (-7C) yesterday.

Even Italy gets snow and a minus 8 C freeze

A ski resort in northern Italy was coated with 10cm of snow on Sunday as temperatures plunged to -8C.

Snow is also falling on Calgary and Alberta too.

Locals are a bit surprised:

Another day, another blackout — Lightning is too much for Australian grid now

Last Saturday at 1pm both Queensland and South Australia were cut off from the national grid. In Sydney 45,000 homes lost power for a couple of hours. Shops had to close. Trains were stopped. Passengers were stranded. Traffic signals were not working on major roads. Chaos. Industrial users shut down in a mass of 725MW of load shedding.

Apparently this was due to lightning.

Once upon a time, Australian states were self sufficient, now interconnectors allow us to share problems:

Two states “Islanded” simultaneously

Two vital interstate power interconnectors blew without warning at the weekend, causing blackouts and critical industrial incidents and isolating two states from the national electricity grid, in a dramatic reminder to Scott Morrison just days into his prime ministership of the nation’s energy policy paralysis.

Queensland and South Australia were exporting power across the interconnectors when they were simultaneously tripped on Saturday, forcing power to be cut to big industrial users and retail customers in NSW and Victoria.

The nation’s biggest single-site power user, the Tomago aluminium smelter in the NSW Hunter Valley, lost power without warning, halting two pot lines for up to an hour. Alcoa’s Portland smelter in [...]

Scottish summers not doing anything they haven’t done for 800 years already

Gotta love a long unbroken proxy.

Scientists looked at 44 pines sites across the Scottish Highlands and used their tree rings to create a continuous temperature series for the last 810 years. Showing admirable restraint, they did not paste on adjusted thermometer records to create a hockey stick effect. Instead we can see that Scottish summers were just as warm in the 1300s, the 1280s and around 1500 as well.

The rate of warming is not unprecedented. The temperature is not unusual. But thermometers don’t tell the same story as the tree rings in the last 50 years. They both can’t be right. Either the tree rings are always unreliable thermometers or the thermometers are placed near ice cream trucks and adjusted up-the-kazoo?

Thanks to CO2Science:

Rydval et al. extended “the previously published Scottish dendroclimatic record (Hughes et al., 1984) by nearly 500 years,” in order to create an 810-year-long proxy over the period AD 1200-2010. The reconstruction was derived from a network of 44 Scots pine (Pinus Sylvestris) sites across the Scottish Highlands from both living and subfossil samples that correlated well with summer (July-August) temperatures.

In placing the most recent warming of the instrumental [...]
