COVID-19: Hockey Sticks

Read this, Boris/Dominic.

Open Mind

Hey! Ron DeSantis!! WE TOLD YOU SO.

Yes, we told you before you did it that this would be the result. By “we” I mean the worldwide community of scientists, especially the experts in the fields of epidemiology and medicine, especially the ones who work in the field at places like CDC and Johns Hopkins, especially the nation’s leaders (like Anthony Fauci) and the people who work for your own state’s department of health.

We told you so, you ignored the warnings, went ahead with your re-opening plans, and the result was this:

It vaguely resembles a “hockey stick.”

Message to Ron Destantis and Greg Abbott: Do Not Remove the Control Rods from a Nuclear Reactor

Open minds: excellent again.

Johnson/Cummings do note this.

Open Mind

I shouldn’t have to say it. But I do.

Nuclear reactors can use “control rods” to control the reaction. Push them in all the way, they’ll slow the reaction so much it will quickly die out. Pull them all the way out, the reaction grows so fast it goes critical — but before it can “go nuke” it melts. Still a disaster.

The “basic” epidemiological model (the SIR model) makes some very basic assumptions, and treats the spread of a disease like COVID-19 in a straightforward manner. It gives rise to the “bell-shaped” curve (the one everyone wants to flatten) we’ve seen in so many news stories.

Of course it’s not “right” — there are too many unaccounted-for factors to believe that. But they also encompass certain purely logical ideas which are known to be correct. Added bonus: the equations are not unlike what you see when you study…

Winter is Here

The OpenMind blog gives some support to the idea that Arctic weather is escaping to bother us with dangerous colds spells. Looks like Jennifer Francis is right. See Why Climate Change is Bringing the Polar Vortex South

Open Mind

The arrival of December marks the beginning of climatological winter (astronomical/calendrical winter begins Deceber 21st this year). We in the USA have seen some cold winters recently, especially in the northern midsection of the country.

“Gagging climate change experts from speaking in the middle of a bushfire disaster is a new low from this government.”

Open Mind

So said Australian Member of Parliament David Shoebridge after bureaucrats attending a climate planning and adaptation conference had been advised not to discuss the relationship between climate change and Australia’s bushfire crisis, the Guardian reports.

Yes, there’s more news of wildfires on the rampage, bringing fear and destruction, made worse by many things including climate change. But the latest isn’t from California; it’s happening in Australia and especially hard hit is the territory of New South Wales. Yes, a lot of things are making wildfire/bushfire worse in California/Australia. Nobody denies that. One of those things is climate change. Those who deny that, are climate deniers.

How bad is beef for the climate?

This is my comment on an interesting post by Tara Garnet on her FRCN blog, Has veganism become a dirty word? There are different views on the effects of methane on climate.

Comment on ‘Has veganism become a dirty word?’ by Geoff Beacon

Actually, methane’s not the problem we thought it was; methane’s temporary, actually methane’s natural.

Tara, this seems to be the view of Myles Allen and Richard Millar  of your Oxford Martin School. As I understand it, their picture is this:

Emissions of methane heat the Earth’s surface for a decade or so before decaying. The rise in the Earth’s temperature causes net heat emissions to space. The long term effect on temperature is small. If keeping Earth’s temperature below a certain threshold is a target, then unless the target is likely in the next decade or so the temporary rise in surface temperature is not important.

There are others that disagree. Continue reading How bad is beef for the climate?

York Plotlands Association (From 2016)

(York Plotlands Association is now defunct)

Background

There are few (if any) examples of lifestyles in Britain which are sustainable. For example, at the new ‘sustainable’ development at Derwenthorpe, York, the carbon footprints of the residents are several times greater than the footprint necessary to avoid dangerous climate change. The York Plotlands Association  promotes action and research into achieving lifestyles that are more sustainable.
