The climate change consensus extends beyond climate scientists

Another fun test of induced electromagnetism:
If you have a copper pipe, like an old piece of plumbing, and a magnet that fits inside it - hold the tube vertical and drop the magnet in.
It will take several seconds to descend through the tube!

The reason is that the magnetic field induces a current going round the tube, creating a magnetic field opposing that of the falling magnet. As the copper has some electrical resistance the currents die down, the field drops off and the magnet sinks down, but by doing so increases the magnetic field further down the tube.

Now if you cut a slit alongside the tube so the current can't go round you'll see in that part it will hardly impede the magnet at all. There will still be local currents, but no longer the strong one going round. It will still impede the magnet slightly, but the difference is enormous.

This principle is used in frictionless shock absorbers. By replacing the tube with coils and controlling the current one can control the level of dampening and venture into active suspension or even temporary ride height adjustment.

Seeking out the above Ars Technica sprung a video about variance in global sea level rising on me:

Stunning how we up North would suffer greatly from Antarctic ice melting but might benefit slightly from melting Greenland glaciers, while things are the exact opposite down south...

A maintenance guy at my previous job told me to take his crescent wrench and walk down the stairs from the 2nd story to the 1st, near the superconducting silicon ingot "pullers". The wrench resisted movement as I held it out from me, and I still have no idea how that works.

Had a death grip on the thing since procedure is to remove all ferrous metal before entering the room, and one guy had a jack get away from him and destroy some protective railing. I'd hate to delay 100,000 Intel chips because I was goofing off with magnets.

Magnetism? You don't know the half of it.

I just don't get how the superconducting magnets can cause objects to be attracted, resist any movement, or repel. What parameters were different to cause a jack to be yanked from a guy? I'd have hated to meet those conditions.

[freebeard]

It's a question that's been asked before: https://duckduckgo.com/?q=icp+magnets

With the jack it was probably going inadvertently going over-center on a fulcrum point.

I have a better handle on electromagnets than permanent magnets. Look for History and Theory of Electricity (aka The Theory of Anti-relativity) by Eric P. Dollard on Youtube. It's 3 1/2 hours.

Oceans Are Warming Faster Than Previously Thought, Research Finds

This is the trend - science has been too conservative on their estimate of time scale and pace of changes in the climate. We are seeing things get worse, at an accelerated rate, than we thought recently.

The oceans are getting 40% warmer than we thought just 5 years ago.

Remember what happens as water gets warmer?

It holds less dissolved gases by volume. So, the ocean will begin to release the carbon dioxide that it has been absorbing ...

Scott Adams has settled on the oceans as a known unknown.

The latest episode (370) has a terse transcript, here's the relevant section:

Why are there gaps in parts of the scientists climate change stance?
The historical data used in the hockey stick graph
It shows an earlier point, before CO2, same hockey stick
ClimateGate emails are a conspiracy theory, completely debunked
Data discrepancies from the past, tree ring experts and proxies
From 1960 to present, tree rings don’t track temperatures
Tree ring data was good in the past…but not now?
Challenge responses about William Happer’s claims and validity
Scientists say you can’t look at just some regions, need whole world
NASA site “proof” of warming is the Arctic…one area?
Some places are warming…but not all? Some are cooling?
Can we accurately measure ocean temperatures, today and historically?
How much of the ocean are we measuring, maybe 1%?

I'm sorry I can't preserve his indenting. vBulletin collapses spaces, disallows tabs and 'prettifies' indenting. You can use Quote to see it, else go to Youtube.

I like Scott Adams, so I'll check it out eventually.

The thing that makes GW/GCC believers sound like religious zealots is that any negative event that occurs they will proclaim "see, that's what global warming does". It could be a colder than normal week in Chicago, and we're then told that it's directly attributable to GW, which is directly attributable to human CO2 production.

Thiests make similar proclamations when something complex is attributed to an all-encompassing God did it explanation.

I don't begrudge anyone for behaving that way because people have their reasons for conviction, and if their beliefs are true, it demands a response. They may very well be correct in their broad reflexive proclamation, but the subject deserves as detailed a response as can be articulated. It isn't useful to say "because God" or "because global warming".

That is a reason I keep coming back to this thread though, because plenty of people on here are willing to provide as much info as they can come up with to support their understanding of things.

Today a news commentary informed that there are already a few flatearthers in the course of engineering in a federal university of Brazil (UFMG).

I would like that such people commit suicide. No kinding.
