"We began by asking our 18- to 20-year-old respondents (82.4 percent of whom reported attending public schools) whether they had ever been taught in class or heard about from an adult at school each of six concepts—four of which are central to critical race theory." A survey based on an blatantly flawed methodology since the questions suggest an answer. The proper questions would have been an open ended one: Where did you learn that etc...?

Concentrations of ozone-damaging aluminum oxides in Earth's atmosphere could increase by 650% in the coming decades due to a rise in the number of defunct satellites burning up during reentry, a first-of-a-kind study has found. And, as satellite megaconstellations continue to pique the interests of private companies, this could be pretty bad news for our planet's protective shield known as the ozone layer. The authors of the study say rising concentrations of satellite-induced pollutants could cause "potentially significant" ozone depletion and thus thwart the ozone layer's slow and steady recovery. https://www.space.com/megaconstellations-threat-to-ozone-layer-recovery It's not a sure thing that this could be the case, as the final paragraph in the article indicates, but obviously it's worth further investigation.

So many words without any kind of evidence. Truly a remarkable achievement.

Thanks, tiger.

Paris has actually gone a long way towards lowering the number of private cars entering the city. Lots of roads now for pedestrians and bike riders only. Less parking spaces. They also held a referendum on keeping cheap ebike rentals available. That was voted down. Too many ebike riders flouted the law by riding on sidewalks. That's an idea that will probably have to wait until new rules take effect that will further reduce auto traffic in Paris. So, then, riding on sidewalks won't be such a temptation.

In a related topic, timber companies claim that they are replacing the forests they cut down with new forests. But what they are actually doing is replacing forests with a tree plantation. A monocrop. It makes no more sense to call that replacement a forest than it does to call a field of corn a meadow.

When petroleum is turned into products not meant for burning, it's not a fue. It seems a quibble but it really isn't. It gives denialists undeserved semantic license. Much in the same way that they claim not to deny climate change but claim that climate is always changing. The fact is that petroleum is used overwhelmingly as a fuel. About 15% is used as a feedstock https://www3.uwsp.edu/cnr-ap/KEEP/Documents/Activities/Energy Fact Sheets/FactsAboutOil.pdf In the case of natural gas, it's even less: In 2015, about 5% was used as a feedstock. https://www.sciencedirect.com/science/article/abs/pii/S0140988320303248 So cutting them out of the fuel industry would drastically lower their polluting affect. And it should be noted that fossil fuel pollution of the air is a major cause of disease and deaths worldwide. https://pubmed.ncbi.nlm.nih.gov/38030155/#:~:text=An estimated 5.13 million (3.63,by phasing out fossil fuels.

If I can save just one poor soul.... That said, I do wonder about why I bother. Clearly, some (most? all?) of them are terminal Take this reply from Novacova to the comments of the three of us It sounds like something out of a grade D Kung Fu movie. Actually, the kind of hokey grandiosity generally voiced by the arch-viilain in the film. Just before he gets his comeuppance How about the claim that there are "the trillions of cracks in the Earths mantle emitting co2". First I've heard of that. It sounds like something out of Jules Verne's Journey to the Center of the Earth. Scientists do know that volcanoes emit CO2 and they are able to measure how much thanks to the greater percentage of C13 in the emissions from volcanoes. Maybe that's what was meant by Novacova in a garbled way? Scientists also know that fossils fuels lack C14. So they know what percentage of atmospheric CO2 and other organic atmospheric gases can be sourced to fossil fuels. The rest of it is just more grandiose argle-bargle. More of the kind of stuff the arch villain or mad scientist spouts in low budget sci-fi films.

False The benefit of using the ERA5 is that this dataset is publicly available, which is particularly important for Saudi Arabia, where access to data from weather stations is limited. ERA5 near-surface temperature and dewpoint temperature data correlate well with weather station observations globally (Li et al. 2020; section 3 of the online supplemental material) and over key cities in Saudi Arabia (section 2 in the online supplemental material). Furthermore, our reanalysis allows investigations of climate changes in the locations where instrumental temperature records have been insufficient or absent. https://journals.ametsoc.org/view/journals/apme/60/8/JAMC-D-20-0273.1.xml

Heartland Institute, which is now at the lead of climate change denialism, for years took money from the tobacco industry to deny the ill effects of second hand smoke. "The Heartland Institute is an American conservative and libertarian 501(c)(3) nonprofit public policy think tank known for its rejection of both the scientific consensus on climate change and the negative health impacts of smoking.[2] Founded in 1984, it worked with tobacco company Philip Morris throughout the 1990s to attempt to discredit the health risks of secondhand smoke and lobby against smoking bans.[3]: 233–234 [4] Since the 2000s, the Heartland Institute has been a leading promoter of climate change denial.[5][6]" https://en.wikipedia.org/wiki/Heartland_Institute

I think someone else needs to inform this person that computers are not made even in part from fuel. Fuel is stuff for burning. Be it petroleum or wood. If you have a house made of wood, would that be a house built out of fuel? It's only fuel if it's used for burning.

Someone else who apparently doesn't understand the difference between climate and weather.

It is the overwhelming consensus of climatologists. So, if you're looking for quackery, you might try searching closer to home.

Which is not the same thing as saying that such things are made from fossil fuels.

No. Medical equipment might consist in part or in whole of chemicals made from petroleum. But not if they were burned as fuel.

And think how much we owe to horses and oxen. There wouldn't have been major world civilations without them. And so what. Just because something got you to where are now, does that mean you're obliged to stick with it forever?

I guess you don't understand the concept of rate of change, it would be nonsense. Otherwise not.

More empty insults from you. You've got nothing.

It's a good thing that there are no such things as tides otherwise your evidence would be worthless.

You gotta get out more.

The world's largest auto market is China China’s EV sales now over 50% https://carnewschina.com/2024/04/20/chinas-ev-sales-now-over-50/

I make it a point not to ask or answer personal questions. Given that we are all anonymous here, there is no way of checking their truthfulness. And even if we could count on the answers, so what? What bearing does that have on the data? I notice that you seem to suffer from the same linking disability that afflicts so many right wingers in this forum. As for Americans wanting to switch back to ICE vehicles, given that the majority sold in the US are Teslas, and they are notorious for the poor quality of their build, I'm not surprised. And the American car market is no longer the world's largest.

Not taking into account the concept of rates seems to be a nearly universal characteristic among denialists.

I think a certain kind of respect should be accorded to Alina Habba. She's a lawyer who, through her demonstrable past incompetence, has actually managed to further blacken the reputation of her profession.

First off, the urban heat island effect has little to do with your claim that air conditioners are emitting more heat. Actually, had you actually read the articles, you might have noticed this: "The urban heat island effect is generally strongest in areas with temperate and humid climate conditions as well as dense rural vegetation. In contrast, where rural surroundings have only scarce vegetation, particularly in deserts, cities, like Cairo in Egypt, often show cooler surface temperatures in summer than their neighbouring non-urban areas." https://joint-research-centre.ec.europa.eu/jrc-news-and-updates/cities-are-often-10-15-degc-hotter-their-rural-surroundings-2022-07-25_en It [Riyadh] is the largest city on the Arabian Peninsula, and is situated in the center of the an-Nafud desert, on the eastern part of the Najd plateau. https://en.wikipedia.org/wiki/Riyadh#:~:text=It is the largest city,part of the Najd plateau. As for the other article.. "The results demonstrate the rise degree is 2.56 °C under inversion conditions and 0.2 °C under normal conditions, which indicates that thermal pollution is serious at stable atmosphere." https://en.wikipedia.org/wiki/Riyadh#:~:text=It is the largest city,part of the Najd plateau. While a/c can have a strong effect on cities where there is an inversion effect, Riyadh is on a plateau surrounded by deserts. So no inversion effect. https://www.sciencedirect.com/science/article/abs/pii/S1359431108001725 And as these graphs show, the increase in heat is not confined to the cities. Quite the contrary, in fact. The top figures show measurement from 1979. The bottom from 2019 Linear trends in (top) monthly maximum of daily maximum (TXx) and (bottom) monthly minimum of daily minimum (TNn) temperature change for (a),(c) the whole year and (b),(d) summer only.
