Global Warning/Climate Change

[Robert]

But no, global atmospheric CO2 has never been 20x what it is now. Not even close.

Oh, contrare. They have been higher for most of the history of the planet then they are now. During he Cambrian, it was 20%+ of the atmosphere, not the .04% it is today.



You can also see that global temps were way higher than now. During the Jurassic, it was close to 10 deg C higher than now. Guess why we find so much petroleum in the ground? It is because of all the CO2 captured by plants and algae during those times it was so much higher.

Let's just ask this one simple question:
At times in the past CO2 concentration in the atmosphere has been as much as 20 time greater than it is now.
Why then have we not experienced the feared runaway global warming that we supposedly can prevent by driving Prius' and replacing our incandescent light bulbs with compact florescents LEDs?
Is there something missing from the models (equations) that somehow result in predictions that don't match the data?

My son loves trees and spends much if his time reading about them. Then he goes in the yard and trims, cuts, plants, and etc.

He takes cut down trees and branches and rubs Aloe Vera on the cut and tries to replant them.

Today he says, "Dad look at this spruce tree I planted after I found it cut down and left at the public wooded park."

Me, "Was there a stump nearby?"

"No."

- "Son, you found someones Christmas tree.".

From the start of wind farms, as i’ve driven by miles+miles of these giant monstrosities across the prairies, thoughts of “future” magnificent SALVAGE business occur. (What goes up, must come down.)

The future is already here. It’s labeled, “decommissioning” costs. A lot is written.
One example:

“Three estimates” ..

Years ago, i asked my mechanical engineering son about buying a Prius. They are common around the nearby state university campus. He advised no, because making the batteries pollutes.

Once a person sees, say, a billion dollars in their future, they are likely to do or say anything to get it.

More ugly junk to clutter up the earth.

As usual, no mention of pollution resulting from manufacture, installation, maintenance, “decommissioning.” No mention if each turbine requires its own (robot?) No mention of cost of starting-stopping blades, or increased wear on blades. No mention of the size of the study. Cost of study to taxpayers.

Killing eagles is a federal offense. Every FEATHER/feather shed is protected.
Individuals face harsh punishments. Corporations are smart. They lobby for special protections, AND taxpayer funding. Today’s most coveted business model.

According to federal law, it's illegal to take a feather shed from an eagle.
The Bald and Golden Eagle Protection Act of 1940 prohibits the possession of eagle feathers by non-Native Americans.

Anyone convicted of violating the law could face a fine of up to $100,000 and a year in jail.

Do you have any idea how many birds are killed by the coal industry? You can look it up yourself. Or here is one US News & World Report Article: https://www.usnews.com/news/blogs/data- ... l-on-birds

Solar: Anywhere from about 1,000 birds a year, according to BrightSource, to 28,000 birds a year, according to an expert at the Center for Biological Diversity.

Wind: Between 140,000 and 328,000 birds a year in the contiguous United States, according to a December 2013 study published in the journal Biological Conservation. Taller turbines tend to take out more birds.

Oil and Gas: An estimated 500,000 to 1 million birds a year are killed in oil fields, the Bureau of Land Management said in a December 2012 memo.

Coal: Huge numbers of birds, roughly 7.9 million, may be killed by coal, according to analysis by Benjamin K. Sovacool, director of the Danish Center for Energy Technologies. His estimate, however, included everything from mining to production and climate change, which together amounted to about five birds per gigawatt-hour of energy generated by coal.

Nuclear: About 330,000 birds, by Sovacool’s calculations.

Power Lines: Between 12 and 64 million birds a year are felled by transmission lines, according to a study published July 3 in the journal PLOS ONE.

That's plenty of birds. But there's no more effective bird killer than species' lifelong enemy: cats. All told, felines kill 1.4 to 3.7 billion birds a year. Sylvester would be proud.

Here is scientific study that concludes wind power kills about birds about about 15-50 times lower rates per kilowatt hour than coal and nuclear: https://www.tandfonline.com/doi/pdf/10. ... 012.746993

And here is a recent study from Norway which found that bird kills can be reduced by 70% by the simple measure of painting one of the three blades black, which increases visibility to birds and increases their ability to avoid being struck: https://www.bbc.com/news/science-environment-53909825

i agree, all bird lives matter.

regarding above references, i believe taxpayers have every reason to “call foul” regarding specific Eagle species (and raptors, and bats) after decades of taxpayer dollars and legal policies have been dedicated to protecting them on federal, state and local levels, INCLUDING major penalties and incarceration for even minor violations -

for any offender, EXCEPT “specially” protected and funded CORPORATIONS.
these corporate violations are either defended or receive a big YAWN. or both.

as far as cats. well, yeah. birds, mice, squirrels.
references are not made whether the biggest feline violators are wild or domestic. i’m not sure how many eagles are victims of wild or domestic cats each year. maybe vice versa ..

Apr 29, 2016 — I've known several people to have seen bald eagles swoop down and kill their own or wild cats lol. So yeah, they do eat cats.

Anecdotal evidence/hearsay, only, Read the article; ...

There are very few animals that can prey on bald eagles, mainly due to the bald eagle's large size and their own predatory prowess. However, some animals, such as squirrels, raccoons, ravens and great horned owls, will attack nests and feed on eggs or nestlings.

just attempting to clarify.

regarding Norway’s paint job idea:
techy folks won’t like it. how much are they into taxpayers for R+D so far? they’re not going away empty handed. and, everything has a price:

Paint and coating manufacturing operations can produce hazardous air pollutants, including heavy metals. ... Chemicals in these substances can react in the air to form ground-level ozone (smog), which has been linked to a number of respiratory effects.

Many folks are dismayed that no attempt at balanced facts/info is attempted.
This breeds mistrust.

People don’t appreciate being railroaded.
