BTW, remember when AOC say the world was going to end in 12 years because of climate change? That was June 2019. Here we are 4 years later. We should all be asking her where she plans to be in eight years (2031) when the world ends?
 

That too... I hope it diminishes the effects, but it may not.

and there was a Bible cult that thought it was going to end before now... So what? No need to distract from our current situation.

It does that for sure... independent of whatever life forms are affected. [pipe]

Hydrogen may not be all it's cracked up to be... because of the smaller molecule, it more difficult to stop 'leaks'.

"The global warming effect of leaked hydrogen is almost 12 times stronger than CO2, shows a new study by CICERO, a climate research center, published in Communications Earth & Environment.

The study fills a gap in our knowledge about the climate effects of hydrogen, a central technology in the energy transition.

Unlike exhaust from burning coal and gas that contains CO2, burning hydrogen emits only water vapor and oxygen. Rather, it is the leaking of hydrogen from production, transportation and usage that adds to global warming.

Hydrogen is not a greenhouse gas, but its chemical reactions in the atmosphere affect greenhouse gases like methane, ozone, and stratospheric water vapor. In this way, emissions of hydrogen can cause global warming, despite its lack of direct radiative properties."

Improved solar cells:

"Chinese scientists have successfully boosted the efficiency of a new generation solar cell to 28% in a race with foreign rivals who achieved the result in December 2018 and have since pushed that level to 33.2% in April this year.

Not waiting for solar perfection, some Chinese firms, including a company established by China’s leading researcher, already have gone into production of perovskite and silicon tandem solar cells (PSC).

This so-called third-generation solar cell is said to be able to convert 50-75% more sunlight into electricity than the traditional silicon photovoltaic (PV) cell.

The product is also 95% cheaper than the silicon solar cell as its key raw material is methylammonium lead iodide, making it a potential great option for countries that want to switch to solar power to meet their carbon neutrality targets."

It's a bit of a start... if the government isn't going to act...

"A Surrey woman will take her fight over a local oil drilling permit to the Supreme Court on Wednesday in a challenge that could spell the end of new fossil fuel projects in the UK.

Judges will decide whether permission for oil extraction in Horse Hill was legally granted.

Sarah Finch is challenging the drilling of four oil wells on climate change grounds.

Surrey County Council told BBC News that it followed planning law.

Ms Finch is bringing the case against Surrey County Council on the grounds that it did not consider some climate impacts of burning the oil when it granted planning permission. Environmental lawyers say the landmark case could affect projects nationwide.

The climate impacts in question - called 'downstream emissions' - are the greenhouse gas emissions released when the oil is used. Ms Finch says these are estimated to be 10 million tonnes of carbon dioxide over 20 years."

LOL, I don't think anyone cited C02 emissions as the basis for their end of days bible belief. The bible has NOTHING to do with the concept of Anthropogenic Global Warming. Any suggestion of this is merely a deflection / distraction.


"Our Current Situation" is exactly the same as it was when AOC said those things. It is a great example of the exaggeration of this issue for political purposes. "This is our WWII" is what she said, isn't it? Suggesting that we need to completely turn our economy over to our government to solve an existential crises.... Like Nazis, Fascists, Authoritarians trying to take over the world after already conquering most of Europe, Asia and the Pacific. If we kept our head in the sand for 12 years, there is a good chance Hitler would have taken over all of Europe and the middle east.

This current situation is, it's gotten a little warmer without and demonstrable damage from such warming. We're justifiably worried that future warming will cause a good amount of damage. That's VERY, VERY different. Think about South Korea or Taiwan (which live with aggressive, totalitarian neighbors who have nuclear weapons and want to take over their countries). You think Global Warming is more of a realistic threat to the lives of people there than what they're currently dealing with. You think poor people in 3rd world nations care more about global warming than they do about ensuring they (and their children) have access to clean water and such.

Imagine trying to convince folks in Venezuela who are digging through trash, eating rats and bugs that the prospect of another 1 Celsius temperature increase is the most important thing in the world.

 
Here is another example. They won't rebuild our local power because of "climate change".


You have to get to the end of the article to see the real reason:

The last sentence said:
State Parks is grappling with a maintenance backlog of over $1 billion, according to the San Francisco Chronicle.

That's right, they don't have the money and don't want anybody asking why.
 
This might be the beginning... This could become a common occurrence.

"Tens of millions in the southern and southwestern United States are under extreme heat advisories. Some cities in Texas have seen temperatures jumping over 45 degrees Celsius. Meteorologist Derek Van Dam takes a look at the forecast for the next 24 hours."

Using my pre-Obama search technique I have found a clear and specific definition of heat wave:


Currently, the definition is much more vague.


Instead of specific heat indexes it is now "abnormally hot" that triggers a heat wave.

Interesting not, the first article says that they observed heat waves becoming less frequent in the south over their period of study starting in the 1960's.

That's pretty much what climate armageddonism is. A religious cult screaming Repent! Repent! The end is nigh!
 
They don't just scream. They deliberately interfere with commerce by blocking roads, bridges, railways, city centres, etc. There needs to be stricter enforcement of laws against these type activities, with minimum sentencing provisions.
 

Rather than repent, maybe try to fix? Not being overly religious, I suspect climate armageddon is more likely... [pipe]

They threw suffragettes and blacks in prison... problem is still not fixed. How about protestors of any kind? Where do you stop. There is the remote possibility that they may be correct. End of this discussion... [pipe]

The activist magistrates will put a stop to that.
 
Dik, you forgot to include the Canadian truckers in your list of persecuted.
 
I didn't forget... that's Turdeau for you...

Is there a need to be concerned? [ponder]

"Ocean temperatures have been off the charts since mid-March 2023, with the highest average levels in 40 years of satellite monitoring, and the impact is breaking through in disruptive ways around the world.

The sea of Japan is more than 7 degrees Fahrenheit (4 degrees Celsius) warmer than average. The Indian monsoon, closely tied to conditions in the warm Indian Ocean, has been well below its expected strength.

Spain, France, England and the whole Scandinavian Peninsula are also seeing rainfall far below normal, likely connected to an extraordinary marine heat wave in the eastern North Atlantic. Sea surface temperatures there have been 1.8 to 5 F (1 to 3 C) above average from the coast of Africa all the way to Iceland."

Improved propulsion for high speed rail.

"A fascinating eVTOL project is about to come out of stealth, showcasing a "breakthrough HyperDrive propulsion technology" that MagLev Aero claims is "dramatically more quiet, efficient, safe, sustainable and emotionally appealing to the mass market."

Representatives from the Boston-based company have made their way to the Paris Air Show, where they're preparing to reveal a very different approach to electric vertical lift aircraft, drawing on the magnetic levitation technology used in high-speed trains.

What we appear to have here is an annular lift fan arrangement. The aircraft's cabin appears to be surrounded by a huge ring-shaped duct, into which at least one large-diameter, many-bladed fan is mounted.

This circular rotor is kept frictionlessly separated from its enclosure using permanent magnets, so it's free to spin when driven. It's driven by a series of distributed, redundant electromagnetic propulsors around the rim."
