Climate Assembly: Weekend 2

Climate Assembly: Weekend 2

The programme for the second weekend of the Climate Assembly can be seen here

https://www.climateassembly.uk/meetings/weekend-2/

There’s a message up at the moment saying: “Stay Tuned. We are live at 1915 GMT,” which is about thirty minutes ago, I think.

Subjects to be covered this weekend are: How we travel; In the home; and What we by, land use, food and farming.

Barry Woods has already given some useful information on participants in comments under the Alex & Andy post. I’ll update this as and when, without necessarily announcing the changes.

Record snowfall in B.C.

Eclipses previous record.

On Wednesday, Feb, 5, Environment Canada measured 13.8 cm of snowfall at the airport, a new record for that date, eclipsing the 10.7 cm of snow that fell on Feb. 5, 1959.

Snowfall amounts were significantly higher in the higher elevations of Kamloops, including Juniper Ridge, Aberdeen and Pineview Valley.

Light snow is forecast to continue through Friday, followed by sunshine and highs above freezing to start the week.

What happens to all the old wind turbines?

Apart from becoming school playground novelty items, what else is there?
One process requires pyrolysis: ‘After first chopping up the blades, pyrolysis breaks up the composite fibres in ovens with an inert atmosphere, at about 450-700C.’
But: ‘The problem is significant amounts of energy are needed to activate the pyrolysis, which might limit its environmental usefulness.’
Indeed, if you’re obsessed with avoiding burning fuels.
Some newer turbine blades are now nearly 100m. long.

Welcome to the wind turbine graveyard, says BBC News. It stretches a hundred metres from a bend in the North Platte River in Casper, Wyoming.

Between last September and this March, it will become the final resting place for 1,000 fibreglass turbine blades.

These blades, which have reached the end of their 25-year working lives, come from three wind farms in the north-western US state.

Each is about 90m (300ft) long, and will be cut into three, then the pieces will be stacked and buried.

Turbines from the first great 1990s wave of wind power are reaching the end of their life expectancy today. About two gigawatts worth of turbines will be refitted in 2019 and 2020. And disposing of them in an environmentally-friendly way is a growing problem.

Burying them doesn’t sound very green. Can they not be recycled?

Wind power goes as far back at least as 9th Century BC Persia, where sails were used to grind grain and draw up water on the windy Sistan plains.

Scottish professor James Blyth built the first windmill to make electricity in 1887, powering his holiday home in Marykirk.

His second powered the Lunatic Asylum, Infirmary and Dispensary in Montrose (later Sunnyside Royal Hospital).

Instead of using cloth to catch the wind like Prof Blyth and the ancient Iranians, today’s turbine blades are built from composite materials – older blades from glass fibre, newer ones from carbon fibre.

Such composite materials might be light and strong, but they are also extremely hard to recycle.

That doesn’t mean they have to go into landfill, according to Don Lilly, chief executive of Global Fiberglass Solutions in Bellevue, Washington.

Mr Lilly has been transforming fibreglass composites into small pellets he calls EcoPoly.

The pellets can then be turned into injectable plastics, or highly waterproof boards that can be used in construction, he says.

Mr Lilly has received interest from “several manufacturers” for his pellets.

He’s also developed a programme to track blades throughout their life cycle, and make it easier to recycle them at the end.

Earth about to enter ‘Mini Ice Age,’ expert warns

No surprise, I’ve been saying this for years. But now we’re starting to hear it from the main-stream media.

Earth about to enter ‘Mini Ice Age,’ expert warns

Robert W Felix

As power-hungry politicians ramp up their man-made global warming propaganda, some scientists warn that a far different type of climate change is headed our way.

We should be bracing for a prolonged solar minimum that could last for decades, until the 2050s, says Prof. Valentina Zharkova, a professor of mathematics at Northumbria University in Newcastle, England.

Zharkova is not alone in saying that the earth is headed into a solar minimum. According to NASA, the Sun will reach its lowest activity in over 200 years in 2020.

“The Sun is approaching a hibernation period,” says Professor Zharkova, who has published multiple scientific papers on solar minimums.

“Less sunspots will be formed on the solar surface and thus less energy and radiation will be emitted towards the planets and the Earth.”

This could cause global temperatures to drop by one degrees Celsius, says Dr. Zharkova, who also has a doctorate in astrophysics.

While a one-degree drop may sound insignificant, it could trigger a slow down in agricultural production. Agricultural seasons could be shorter for several decades.

“This would dramatically effect food harvests in middle latitudes, because the vegetables and fruits will not have enough time for harvesting.”

Those shorter growing seasons could lead to food shortages and famine, according to Zharkova. “It could lead to a food deficit for people and animals, as we have seen in the past couple of years when the snow in Spain and Greece in April and May demolished the veggie fields, and the UK had a deficit of broccoli, and other fruits and veggies.”

Zharkova also pointed to recent unusual chills in Canada and Iceland as evidence of the Grand Solar Minimum (GSM) already taking hold.

“We can only hope that the mini ice age will not be as severe as it was during the Maunder minimum,” Zharkova said.

The Maunder Minimum, known as a Grand Solar Minimum (GSM), occurred from the mid-16th century until the early 17th century, and coincided with a time on Earth known as the Little Ice Age, when millions – millions! – of people died of starvation.

“The reduction in temperature will results in cold weathers on Earth, wet and cold summers, cold and wet winters,” said Zharkova. “We will possibly get big frosts as is happening now in Canada where they see [temperatures] of -50C.

One solar scientist, Matthew Owens from the University of Reading, believes that any cooling effect of a GSM will be “vastly offset” by anthropogenic global warming.

Although this warning was published in The Sun and The Express, which many of my readers ridicule, it was also published in The New American and on msn.com, indicating to me that the idea of mini ice age is slowly working its way into the mainstream media.

One of the things I found laughable was The Sun’s assertion that “Most of the effects will be harmless.”

Famine and mass starvation are “harmless”?
