It's hard to take the article seriously when they say something like,
STEM is an academic enrichment program that encourages girls — and other minorities — to pursue careers in the fields of engineering, computer science, science, business management, entrepreneurs, and mathematics.
The real problem was the Democratic Mayor of Flint got cheap and didn't want to pay the Democratic Mayor of Detroit for clean treated water, so they got the water out of a cesspool called the flint river and didn't put any of the EPA required corrosion inhibitors in the water.
Just about any city in the US is one "Forgot to add the corrosion inhibitors" away from being the next Flint.
However, any reactor design which requires external power to scram is inherently unsafe and should be decommissioned immediately, because unforeseen events occur, and develop into unforeseen consequences.
Westinghouses AP 600 and AP1000 have a passive cooling system which will activate without operator intervention if necessary, requires no external power, can cool the reactor for 72 hours without power and can be replenished.
Yes actually it was an unsafe design, It had a positive void coefficient of 4.7 beta, which means the reactor increases power if the coolant boils and it had graphite tipped control rods the reaction literally has to increase before it starts to shut down. These control rods make the RBMK reactors unstable at low power. Additionally the positive void coefficient makes the RBMK very susceptible to xenon oscillations. With a safer design that had a negative void coefficient, the same "test" would have been much more difficult to impossible.
In HVAC the inductive impedance is much more significant than the resistance, the AC also needs about 23% more peak voltage and amperage to achieve the same KVA as HVDC would. Where HVDC really shines is connecting to grids with slightly different phases. Wind turbines have alternators that output AC, but that is converted to DC, then inverted back to AC in sync with the power grid. If the rectifier bridges in switching power supplies were beefed up, they'd be able to run on anything from 110 - 240 volts, AC or DC.
But 1950's technology should not be propagated or even used to replace old nuclear reactors. There should be a working model for non-fissile (thorium) nuclear reactors which then can be propagated commercially, modern designs that make nuclear meltdowns near impossible, and a sustainable program to reprocess and safely dispose of nuclear waste.
Depending on what happens in Bankruptcy Court, that may never happen, Westinghouse was major manufacturer of Gen III and Gen III+ reactors.
Sorry wrong word substitute Caustic for Corrosive. Still the ocean has numerous powerful buffer systems involving sodium bicarbonate, sodium carbonate, sodium sulphate, Calcium Carbonate, calcium sulphate, magnesium carbonate and magnesium sulphate; any pH changes from CO2 are going to be minuscule and buried in natural diurnal variations. Corals and mullusks have survived much higher and much lower CO2 levels over the millions of years they've been on this planet.
oh for fucks sake, how many times "A tree is NOT a thermometer!", Too many interdependant variables to extract fucking temperature.
here's a few:
Amount of animal piss/shit around tree - changes growth (non linear)
Water too much - changes growth (non linear)
Water too little - changes growth (non linear)
Cloud cover - changes growth (non linear)
Amount of light - changes growth (non linear)
Cold - changes growth (non linear)
Heat - changes growth (non linear)
Amount of Co2 - changes growth (non linear)
Oxygen levels - changes growth (non linear).and even more.......
So how exactly do you find the exact reading of all the rest, just to pull temperature?
I don't disagree, but you have to assume that if Dr Mann thought the tree rings were a valid proxy for thermometers, then plotting both tree ring data and thermometer data would lend support to that; by splicing without notice Dr. Mann shows even he had doubts and may have obscured the change for political reasons rather than scientific.
Then maybe he was malicious, because his "hide the decline" was totally unethical if he knew what he was doing.
That's the way I assumed it, but I was trying to maintain a neutral voice and let the facts speak for themselves. Dr Mann is a bit thin skinned and has demonstrated a tendency to be litigious.
Cool a video by a Scientist who when having something pointed out to him using modern and novel visualization technique, assumes it's unprecedented because He has never seen it before; and otherwise completely supports my point.
...some tree ring series started showing declines in temperatures that weren't matched in observations by actual thermometers...
Slow down there, cowboy!
Tree ring data is used to estimate temperature changes occurring during the past before there were thermometers (or humans for much of Earth's past history for which tree-ring data is used, for that matter).
Can't be comparisons between two data sets when one set does not exist!
Now that is just ignorant, we still have trees, we have thermometer, Mann could easily plotted the tree proxy data, and the thermometer data as two coexisting dataset and an observer could visual judge thee correlation between the two plots. Instead he spliced the two and presented them as if they were one; many people interpret this as an act of wilful deception.
Dr. Mann worked at the University of Virginia in the United States, It was Dr Jones at the CRU, Climatic Research Unit, in the University of East Anglia in England. Dr. Mann has a degree in mathematics and presumably took one or more courses in statistics. Dr. Jones supposedly can't even use an excell spreadsheet.
Your Neighbor told you your house is on fire because he saw the fireplace was lit through the window.Do you:
A. Call the fire department? B. Accuse the neighbor of telling you your house is on fire that "Fire is just somebody's religion!" C. Convene a study to determine if the house really is on fire, and if so, if it was due to spontaneous combustion or if there's a arsonist about? D. "Blame Liberals!" E. Post to Facebook or instagram?
This is just more bullshit, a pathetic attempt of Mann to make believe he is still relevant. The exact same jet stream patterns happened during the 1997–98 El Niño.
Or we could, you know, work to reduce CO2 emissions. In the end we'll have to do it anyways, so why not start now? Why just build higher levies and give the middle finger to brown-skinned people unlucky enough to have been born in developing nations?
We did reduce CO2 Emissions and in fact our emissions are trending down as well; now China on the other hand seems to get a free pass by alarmists.

Mr Westinghouse also invented the Air Brake, without that all of our trains and heavy trucks would run away and crash.

Don't know if you know this, but coal is buried carbon deposits from millions of years ago.
In other words, natural trash.
Coal is dying, it's was more a matter of Trump allowing a graceful natural death or Obama's accelerated forced death.

The ocean is not acidic, it is moving toward being minutely less corrosive.

Careful, you're making sense. You see the point is not to fix the supposed climate change, but to continue to study it.
but its gonna suck when summer is 107 instead of 97.
Cool, too hot to fuck, population crisis averted, Malthus bitch slapped again!
Seriously, using The Union of Concerned Scientists as a reference isn't going to advance your point with your targeted audience.

No Real Scientist uses the term "law" any more; even Newton's "Laws" of Motion only yield correct solutions under limited conditions.
