Be gone all you gas cookers and heaters in Victoria! We need colder weather. Seriously?

Evil weather-destroying equipment will be banished:

Victorians building new homes will be denied the choice to pick their preferred heating and cooking appliances in the hope that this will stop storms and droughts for their great grandchildren.

As household prices rise, the money that could have been used for holidays, health, or education will be used to enrich a few corporations and make a small percentage of the population feel important and calmer.

If only the low carbon revolution was clean, green and cheap, no one would have to ban anything.

Suffer the children:

Push to turn off gas to help reach state’s climate goal

Tom Cowie and Nick O’Malley, The Age

Gas appliances including heaters, hot water services and cooktops would be phased out under a proposed moratorium on new gas connections to Victorian households to help the state achieve its 2030 target to cut carbon emissions by up to 50 per cent.

Victorians are the nation’s biggest users of natural gas for heating, hot water and cooking due to the state’s historically cheap and plentiful supply piped in from Bass Strait since the 1970s.

A cloud of Covid variants circles the globe

Mutations of SARS2 are roaming. Currently there are 19 million active (known) cases of Covid. Due to copying errors, mistakes are accumulating in the genes of the virus. It’s a relentless process of trial and selection. A trillion monkeys on keyboards blindly working its way around vaccines, and immune systems. To beat this, we need to understand it.

Below is a map of known variants created from the samples which have had full sequences done. This is the remarkable “Nextstrain“ — an opensource tool. I have labelled a few clusters by their “country names”, (though we’re not supposed to do that. Let’s all say “WuFlu”.)

The family tree of SARS-Cov-2 starts at the bottom left corner with two samples from Wuhan around Christmas 2019. This is called the 19A clade, which appears to have almost died out now, though there are still remnants left of this original virus in corners like Iran and PNG. Otherwise, the Wuhan 19A virus has been superseded by its children.

The branches and time marches to the right.

The code for one full virus is 29,000 bases long and as best as I can tell, all the dots […]

China is the Fastest growing Nuclear Power in the world

The CCP say that China has to stay with coal, but The West ought pay attention more to the rapid growth of nuclear power. Last September I noted that China was poised to be the largest global nuclear power by 2030, overtaking the USA in the next nine years. In the last twenty years, China has increased its fleet of nuclear power reactors from three to 49, with 17 more plants under construction. That means it will soon surpass France which has 57 reactors. At the rate the USA is closing plants, China may hit the No 1 spot faster than expected.

China has also opened an experimental fusion reactor called the Artificial Sun, while the ITER international consortium keeps delaying the opening of the French fusion experimental reactor.

Rise of Nuclear Power in China.

It is sobering to know that despite the rapid growth of nuclear, it is still only 5% of the total energy supply in China.*

Electricity generation in 2019 increased by 5% compared with the previous year, to 7.3 PWh, according to figures published by the China Electricity Council. That from fossil fuels was 5045 TWh (69%), from hydro 1302 TWh (18%), […]

Zuckerberg uses “climate change” as a shield to cover for his obscene wealth

“Climate change” is just the handy branding for the uber rich to hide behind

Mark Zuckerberg, the Facebook chief who deletes people to save The Earth, is also apparently working on owning a Hawaiian island by suing the hapless natives who were in the way. His holiday house on Kauai Island is apparently worth $80 million, is 57,000 square feet, and has 8 bedrooms and nine baths.

Mark Zuckerberg, Priscilla Chan pick up 600 more acres in Hawaii

Conor Skelding, New York Post

The Big Tech billionaire and wife Priscilla Chan snatched up 600 additional acres on the island of Kauai — and an existing online petition demanding that Zuckerberg stop “colonizing” the Aloha State is now well over 1 million signatures as of Saturday.

The pair purchased the land for $53 million from the local nonprofit Waioli Corp., according to Pacific Business News.

The couple now owns more than 1,300 acres on Kauai, known as the “Garden Island” for its extensive tropical rainforests.

The online petition, with 1,014,219 signatures, says, “Mark Zuckerberg is the sixth richest man in the world … and he is suing Native Hawaiians in […]

Chinese official says solar and wind are too intermittent and unstable. They must use coal.

China seems to operate in its own bubble of rules

Imagine the apoplexy if our ecology minister said we’d fund coal power in the third world? Why is it only China that gets to build coal at home and abroad? What kind of developing nation can’t afford to run on “solar and wind” but is rich enough to be helping build coal plants in other nations too?

China has ‘no other choice’ but to rely on coal power for now, official says

Evelyn Cheng. CNBC

“China’s energy structure is dominated by coal power. This is an objective reality,” said Su Wei, deputy secretary-general of the National Development and Reform Commission. CNBC translated his Mandarin-language comments, which he made late last week following Xi’s separate remarks at a U.S.-led global leaders climate summit.

“Because renewable energy (sources such as) wind and solar power are intermittent and unstable, we must rely on a stable power source,” Su said. “We have no other choice. For a period of time, we may need to use coal power as a point of flexible adjustment.”

He added that […]

Court rules Germany needs *more carbon action*. Who cares what voters think? Young people have right to climate protection.

German climate change law violates rights, court rules

BBC

Germany’s climate change laws are insufficient and violate fundamental freedoms by putting the burden of curbing CO2 emissions on the young, its highest court has ruled.

It says the law fails to give enough detail on cutting CO2 emissions after current targets end in 2030. “The provisions irreversibly offload major emission reduction burdens on to periods after 2030,” it found.

Like the EU legislation, Germany’s domestic climate change law provides for a 55% reduction in greenhouse gases by 2030.

But the German Constitutional Court said on Thursday that current measures “violate the freedoms of the complainants, some of whom are still very young” because they delay too much of the action needed to reach the Paris targets until after 2030.

Since when did young people have right to be protected from climate change?

It’s time for other young people to sue the court, and the government. Germany’s climate change laws are wildly expensive and pointless, and will have no measurable […]
