Solar levelized cost of electricity is 29% lower than any fossil fuel alternative

... just because we can harness power from the sun or wind means it is really that much "greener" than other stuff, when the entire picture is considered...
Well said, but you also have to look at getting coal or gas out of the ground, the costs of refining it, the costs of shipping it, and the efficiency. For example, we burn some percentage of crude oil just to refine it. Gasoline engines waste about 70% of the gas put into them (e.g., not converted into miles).
... "the science is settled!" - no, science is never "settled."...
You're right about that:
  • Is the Earth Round - Still not settled, Flat Earthers say it ain't so.
  • Earth is the Center of the universe - Still not settled as no matter where you point a telescope there's something out there at the edge.
  • Germ Theory Disease - Heavily disputed by believers in the 3 second rule
  • Heliocentrism - I'm sure there are geocentrists out there somewhere (or will be after they look up what it means ;-)
But who are you going to trust, politicians and fuel companies with a vested interest? Or Scientists from around the world?
Did you know Fossil Fuel companies knew about it before it became "accepted" science in the 90s? See https://www.npr.org/2023/01/12/1148...ere-accurate-decades-ago-still-it-sowed-doubt

The original book called Merchants of Doubt exposed the facts around why cigarettes causing cancer was disputed for decades by the tobacco industry. How do you keep the science unsettled? One example was they hired scientists to do research, since scientists were still doing research, how could the issue be settled? Fun huh? Oh, the fossil fuel guys hire the same PR firms.

All the mining equipment burns fossil fuels, and all the EV's are charged with Coal.
Not all, plus we could convert them to electric and power them with renewables. Will Prowse's EVs are solar powered, so are mine! ;)
 
All ?
Most. Please do without all the products in the list I attached before anyone preaches about petroleum products. Or start your own company making alternatives first.

Also, how much does that electric dump truck cost, how many of them are there, and how did they mine the materials to build it( Kids in the congo using bare hands?)
I hope there is no PLASTIC or rubber in it or on it, and the tires are made of wood.

Can we see a graph of the world market for climate scientists vs. year?

Kind of like stuffing the Supreme Court to get the majority to say what you want.

Control the narrative. Use the phraseology that best works on people's psychology.


We've heard of the internal communications, meetings, funding which were used to bury the initial belief that Covid could have leaked from Wuhan lab. Don't expect anything less when it comes to the big money surrounding "climate change". Or "fossil fuel". Trust no-one. "Do your own research" ? :ROFLMAO:
 
Its numbers match up with other observations and they're not unaware of the problems being on a volcano. You might be interested in: https://gml.noaa.gov/ccgg/about/co2_measurements.html

After I helped develop an Atomic Mass Spectrometer (RGA, gas analyzer), the guys said the were able to detect the ppm level of Krypton present in air. I said, "Didn't you spill 200 cubic feet of Krypton in the lab?"

But it later was also detected in our Tokyo facility, which had never used bottled Krypton.

When we first saw the peaks, it had all 5 peaks, isotopes of the atom. But some were at the wrong atomic mass. My RF oscillator was unstable, causing mass-axis shifts and showing peaks that didn't exist. After I improved that, the low-level side peaks were seen in the correct locations. (need log scale to resolve all)

really ?
we're down to tornado's now ?

i mean mass flooding, snow loads going wild in europe , forrest fires on an unseen scale...

i know it it all a bit scary, but putting ones head in the sand, and keep doing what we have been doing won't help here

You just rattled off a bunch of stuff without qualifying anything you said.

I can't fathom why someone wouldn't understand that an increase in the cost of a given disaster in a given wouldn't increase as the number of households, businesses and infrastructure in the area increased.

It's a manipulation tactic and it works on the easily manipulated who instantly think it's because the disasters are getting worse and increasing in number and won't bother looking at the data corresponding with the magnitude instead of the fact that a normal hurricane in Florida will now be more expensive VS what it was 50 years when the population was a 1/4 of what it is now and of course the fact that houses have gotten more expensive (which isn't taken into the inflation number)

Not that the Global Warming enthusiasts will understand that.

Hey SVETZ, are Solar Panels and windmills manufactured without fossil fuels?

If yes, provide examples and if not please tell us why. Thanks.
 
So, we should stop all mining immediately? I guess I don't understand why coal mining is good, but lithium mining is bad.
We burn the coal and oil. We dont burn the lithium.

Holy crap.

I didn't say stop mining everything immediately. I also didn't say lithium mining is bad and coal mining is good. Don't put words into my mouth. Strawman argument much?

I simply said to look at the big picture and realize all this stuff has its ecological impacts. From there we can make judgements and decisions to be smart about it, reduce impacts, etc.

The big picture ... if everything that solar replaces comes from mining, then using mining as an arguement not to expand solar seems kind of stupid.
 
But solar panels are useless at night, so you need either batteries or some other form of generation when dark/cloudy/etc.
also quite true, you need storage, "batteries" really just mean storage which can be pumped hydro, which would not require any mining of lithium. Some locations are well suited to pumped hydro, others are not.
I ordered a 12 and 24 volt Sodium battery last month to try them (not arrived yet), to test the low temperature capability. Sodium is one of the most plentiful elements on earth, including all the oceans.

I believe Watts247.com sells Sodium batteries, but he calls them Silicate batteries. They are supposedly great for low temp environments, and do not need a BMS, so probably good in an EMP also.
The only drawback is the lower cycle count (3000 at 60%).
 
...Trust no-one. "Do your own research"
Very wise words! Fortunately, I did and encourage everyone to do their own research as it's a pretty important topic.

I used to think that climate change was noise and BS until I set out to research and possibly disprove it. Looking into all the flaws I knew of I found they were all bogus or were accounted for in the model. Looking into the proofs, I found they were more complex than I had thought. Looking into the models I found they have been spectacularly accurate over the last ~30 years. For example, here's the 2005 forecast/hindcast with me putting red dots for the actual measured values for the future forecast (the outer lines are the range of accuracy for the model):

The models are only as good as what the scientists know about. Sadly, there are a boatload of unknown things that aren't in the model that people have heard of as Tipping points, e.g., if/when the AMOC stops, melting of ice with trapped methane.

But that's just me. I agree people should look into on their own, although from my experience I can tell you it isn't easy. Scientists don't argue much about if it's happening, but happily argue about nitty gritty. The PR firms have innuendo and misleading information everywhere that's easy to fall prey to. Basically, I advise just picking one thing at a time and digging into it. For example, one of the ones I always hear is it went from global warming to climate change because they couldn't sell global warming. But that's just a misleading untruth. This NASA article talks about it, they're not the same thing. Global warming was where the question started in the 90s to see if the greenhouse effect was really affecting the Earth. Once that was unequivocally proven to be true (see graph below), governments from around the world, via the UN, established the IPCC to see how global warming would change the climate. It only got twisted into a joke by the PR mills and fossil fuel companies, like the tobacco companies, started spreading doubt that it wasn't settled science (settled in the sense we know for a fact that the temperature is rising and it's from more than things like volcanos, not settled in that it's more like the theory of relativity in that it fits most of what we know, but doesn't explain everything). Five different institutions below calculating the global temperature, and not one of them agree! Obviously not settled. ;)

Does that mean information from the scientist is pure? I don't think so. I believe there is government coercion in the IPCC reports. Mainly because a panel of political bodies gets to review and adjust the 'language'. But, to me, it seems like the coercion is to downplay the threat. That is they get to change the language, not the numbers.

Given how out of context the news is just to be sensational (e.g., Florida will be underwater, it's true if we do nothing... it will happen in a hundred+ years, but right now it's just a few millimeters a year and only very low areas are affected) I can see why they want to make it less alarming. But, I dislike that it's been politized and the government is doing so little because it's like accruing debt. The more we accrue the more expensive it will be to undo it.

Can we see a graph of the world market for climate scientists vs. year?
Sure! This is just the U.S., probably not representative. Although these numbers are "employed" and most companies don't care about doing climate change research (they're probably more for environmental impact assessments and such). Most climate-related papers published are from college professors using slaves unpaid students for the research.

I think what you probably want to really know is how much money is being pumped into promoting climate change versus how much is pumped into anti-climate change rhetoric.

Universities get grants to study things, but mainly that's to keep the universities' doors open. The IPCC is funded by regular contributions from its parent organizations WMO and UNEP, and voluntary contributions from its member governments and the UNFCCC. Obviously, that's a pittance. But, the IPCC doesn't do or fund research, they just take what's published and have experts assemble into their reports and more experts review it... there's so little money those only come out every few years.

On the other hand, the anti-climate change is well funded, no surprise considering it is a multi-trillion dollar industry to protect. Fossil fuels are also always big contributors to politicians; whereas there are few contributors of much smaller amounts from climate scientists. I can find things online about the billions fossil fuels have spent on confusing the public, but they're all climate sites so need to be taken with a grain of salt.

But, right now I think there's very little money on the side that climate change is real, versus a lot of money in saying it's a hoax. That doesn't mean people aren't positioning themselves to make money off it. Fossil fuel companies have been developing carbon capture technology for decades. In fact, even fossil fuel companies now say climate change is real and we need to do something about it:
"We know enough based on the research and science that the risk (of climate change) is real and appropriate steps should be taken to address that risk," Ken Cohen, Exxon's government affairs chief, said in an interview. ref

Breathing contributes to global warming – study​

Methane and nitrous oxide found in human exhalations are worse for the environment than carbon dioxide, scientists say

Human breathing contributes to global warming, according to a study published Wednesday in PLoS One. The authors argued that human respiration’s contribution to climate change has been underestimated and merits further study.

After measuring the gas composition in the exhaled breaths of 328 study participants, the researchers concluded human breath comprises 0.05% of the UK’s methane emissions and 0.1% of its nitrous oxide. Both of those gasses “have a much higher global warming potential than carbon dioxide,” the study notes.

Exhaled human breath can contain small, elevated concentrations of methane (CH4) and nitrous oxide (N2O), both of which contribute to global warming,” the researchers, led by atmospheric physicist Nicholas Cowan of the UK Centre for Ecology and Hydrology, wrote. “We would urge caution in the assumption that emissions from humans are negligible.”

While Cowan explained that “CO2 contribution in human breath to climate change is essentially zero” because plants absorb nearly all the carbon dioxide humans breathe out, the other two gasses are left in the atmosphere. Methane traps 80 times the amount of heat as carbon dioxide during its first 20 years in the atmosphere, though this potency decreases over time.

A detailed analysis of test subjects’ diets failed to yield any indication that meat eaters produced more of either gas. While all test subjects exhaled nitrous oxide, only 31% exhaled methane. These individuals, referred to as “methane producers” in the paper, were more likely to be female and over 30 years of age, though the researchers were unable to determine why this was the case.

The study authors cautioned that their research only looked at breath and called for further research into the total picture of human gas emissions, insisting it could reveal more about the “impacts of an aging population and shifting diets” on the planet.

In recent years, environmental campaigners have focused on methane emissions from cows, whose herbivorous diet is broken down by methane-producing bacteria in their multiple stomachs. Policymakers’ focus on the resulting methane-tainted belches and farts have been the subject of much parody from climate change skeptics.

The UK has legally committed itself to reducing greenhouse gas emissions by 78% by 2035 compared to 1990. Residents have been strongly encouraged to reduce meat consumption in order to achieve this goal, with some estimates placing the share of global greenhouse gas emissions from raising livestock for meat at 15%. However, the researchers behind Wednesday’s study pointed out that shifting to a high-fiber vegetarian diet could potentially cause more methane and nitrous oxide emissions, a phenomenon they called “pollution swapping.”
