The Sound Of Settled Science

Unsettled Science 26 Comments

It’s Alex Jones’ world and we’re just living in it.

Researchers in Canada found women who drank fluoridated tap water while pregnant had children with slightly lower IQ scores than women who lived in non-fluoridated cities.
 
The message from public health experts, however, is “don’t panic”.
 
While the authors of the study claim the research “raises possible concern”, other researchers say the findings don’t move the needle much — if at all — on the question of fluoride safety.
 
“The overwhelming body of evidence is still supporting water fluoridation,” said Matt Hopcraft, associate professor of dental public health at the University of Melbourne.
 
“Here’s a single study that points a little in the other direction. I think we just need to be cautious.”
 
Water fluoridation began in Australia in the 1960s as a way to help prevent dental decay. It’s been heralded as one of the greatest public health achievements of the 20th century.

Now do birth control pills and testosterone.

A Circular Plastic Future?

Science 21 Comments

…a team of researchers at the U.S. Department of Energy’s (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) has designed a recyclable plastic that, like a Lego playset, can be disassembled into its constituent parts at the molecular level, and then reassembled into a different shape, texture, and color again and again without loss of performance or quality. The new material, called poly(diketoenamine), or PDK, was reported in the journal Nature Chemistry. […]
 
Unlike conventional plastics, the monomers of PDK plastic could be recovered and freed from any compounded additives simply by dunking the material in a highly acidic solution. The acid helps to break the bonds between the monomers and separate them from the chemical additives that give plastic its look and feel.
 
“We’re interested in the chemistry that redirects plastic lifecycles from linear to circular,” said Helms. “We see an opportunity to make a difference for where there are no recycling options.” That includes adhesives, phone cases, watch bands, shoes, computer cables, and hard thermosets that are created by molding hot plastic material.

Hope it works.

Y2Kyoto: Our Disappearing Wetlands

John Pomeroy warns (Saskatoon Star Phoenix) on June 15th, 2006;

Following is the opinion of the writer, a geography professor at the University of Saskatchewan and director of the centre for hydrology. He holds a Canada Research Chair in Water Resources and Climate Change.
 
Streams, sloughs and wetlands may not be sustainable under climate change, and the slightly milder winters anticipated under global warming may dry out the Prairies. […]
 

 

On June 5, the United Nations Environment Programme announced a study that shows the world’s desert and arid regions are at risk of becoming even more parched. Research at the University of Saskatchewan supports this, showing the Canadian Prairies could be drying out due to more moderate winters.

Well, it’s 2019 and what do ya know?

A leading Canadian water security expert says a recent Environment and Climate Change Canada report highlights the need to change how Saskatchewan designs and builds communities and infrastructure. […]
 
Pomeroy said his research and that of his colleagues shows some of the effects the process has already had on Saskatchewan.
 
He noted the province now sees 50-per-cent more multi-day rainstorms in the summer months than it did in the 1950s and pointed to the 2014 floods that caused billions of dollars of damage.
 
He said what stands out in particular about those floods was that they happened in June and July and were caused entirely by some 200 millimetres of rainfall, whereas most flooding has historically come with the spring melt.
 
“We simply never had flooding of that nature ever reported before since the western settlement of the region, nor is it noted in the traditional knowledge of the Indigenous peoples in the area,” Pomeroy said.

That’s right. He’s the same quack whose dire drought prediction I’ve been mocking for the last ten years.

Y2Kyoto: Make Greenpeace Great Again!

Leftie twitter is apoplectic, but this one kindly posted the video.

Bumped for update: Greenpeace has gone into full blown denier mode, claiming Moore was never a co-founder.

The Wayback Machine says otherwise.
