Oh... wait.
Collapse is common when the engineers are incompetent. From today:

At least 14 killed as billboard collapses in Mumbai during thunderstorm

The billboard collapsed on some houses and a petrol station next to a busy road in the eastern suburb of Ghatkopar following gusty winds and rain. Mumbai’s municipal corporation said 74 people were taken to hospital with injuries following the accident, of which 31 were discharged.

No conclusion can be drawn about solar power from the collapse of solar collectors in the wind or the collapse of a billboard, other than being a cheapskate causes failure.

Well yeah... that's bad. It's also probably not engineers but low skilled workers with a day or two of training putting these things together.

But the real probem with solar is that despite costs coming down it's still a very expensive technology and requires a large footprint for the relatively small output. And the fact that it needs the sun to work means it needs to be exposed to the elements 24/7. So even if it were installed with premium parts by actual skilled engineers, it's requires a lifetime of regular maintenance labor costs to keep operational until it ends up in a landfill.

This is yet another idea with great potential in the future that was forced into regular usage before it was ready to be.

Many plans that are eating up money are fueled by wishful thinking rather than by rational thought. Let’s have a look.

The Federal Aviation Administration reauthorization bill approved Wednesday by the U.S. House of Representatives includes language allowing Boeing an extra five years to produce 767 freighters for FedEx and UPS beyond the date when international standards mandating cleaner engine types kick in.

The bill gives Boeing (NYSE: BA) a bridge, in case the express carriers need extra capacity, until it can develop a new freighter next decade. Multiple industry sources familiar with the process said FedEx (NYSE: FDX) and UPS (NYSE: UPS), via surrogates, joined Boeing in lobbying Congress for a reprieve from the Jan. 1, 2028, production deadline. The legislation previously passed the Senate and will be sent to President Joe Biden to sign into law.

At face value, a split from international consensus would limit operation of freighters produced between 2028 and 2033 to the domestic U.S. market, but it’s possible some countries could permit access, according to experts. Freighters delivered before the end of 2027 aren’t covered by the enhanced carbon emission rules and won’t face any restrictions.

Under International Civil Aviation Organization (ICAO) agreements, commercial aircraft manufacturers effectively can’t sell aircraft that don’t meet the 2028 carbon emissions standards. The U.S. Environmental Protection Agency adopted the fuel efficiency standard in 2021 with the FAA following suit in February.

UK breakthrough could slash emissions from cement – May 22, 2024

https://www.bbc.com/news/articles/cxee01m5yero

Scientists say they've found a way to recycle cement from demolished concrete buildings.

Cement is the modern world's most common construction material, but it is also a huge source of planet-warming gas emissions.

That is because of the chemical reactions when you heat limestone to high temperatures by burning fossil fuels.

Recycling cement would massively reduce its carbon footprint. Researchers say that if they switched to electric-powered furnaces, and used renewable energy like wind and solar rather than fossil fuels, that could mean no greenhouse gases would be released at all.

And that would be a big deal. Cement forms the foundation of the modern economy, both literally and metaphorically.

It is what binds the sand and aggregate in concrete together, and concrete is the most widely used material on the planet after water.

It is also a major driver of climate change. If cement was a country, it would be the third biggest source of emissions after China and the US, responsible for 7.5% of human-made CO2.

The problem is the material’s uniquely polluting chemistry.

It is made by heating limestone to up 1600 Celsius in giant kilns powered by fossil fuels.

Those emissions are just the start. The heat is used to drive carbon dioxide from the limestone, leaving a residue of cement.

Add both these sources of pollution together and it is estimated that about a tonne of carbon dioxide is produced for every tonne of cement.

The team of scientists, from Cambridge University, has found a neat way to sidestep those emissions.

It exploits the fact that you can reactivate used cement by exposing it to high temperatures again.

The chemistry is well-established, and it has been done at scale in cement kilns.

The breakthrough is to prove it can be done by piggybacking on the heat generated by another heavy industry – steel recycling.

When you recycle steel, you add chemicals that float on the surface of the molten metal to prevent it reacting with the air and creating impurities. This is known as slag.

The Cambridge team spotted the composition of used cement is almost exactly the same as the slag used in electric arc furnaces.

They have been trialling the process at a small-scale electric arc furnace at the Materials Processing Institute in Middlesbrough.

The BBC was present when the first high grade, or “Portland”, cement was produced.

They are calling it “electric cement” and described the event as a world first.

The lead scientist, Cyrille Dunant, told the BBC it could enable the production of zero-carbon cement.

“We have shown the high temperatures in the furnace reactivate the old cement and because electric arc furnaces use electricity they can be powered by renewable power, so the entire cement making process is decarbonised.,” he said.

He said it also makes steel recycling less polluting because making the chemicals currently used as slag has a high carbon cost too.

Mark Miodownik, Professor of Materials and Society at University College London, described the way the Cambridge team have combined cement and steel recycling as “genius” and believes, if it can be made to work profitably at scale, it could lead to huge reductions in emissions.

“Can it compete against the existing infrastructure that is very unsustainably going to keep pumping cement into our lives”, he asks.

“Cement is already a billion-dollar industry. It’s David and Goliath we are talking about here.”

The hope is electric cement will be cheaper to manufacture because it uses what is essentially waste heat from the steel recycling process.

Spanish company Celsa will attempt to replicate the process in its full-scale electric arc furnace in Cardiff this week.

The Cambridge team estimate, given current rates of steel recycling, their low carbon cement could produce as much as a quarter of UK demand.

But the use of electric arc furnaces is expected to increase in the future, potentially allowing more “electric cement” to be produced.

And, of course, the process could be duplicated all over the world, potentially cutting the emissions from cement dramatically.

Two new studies reveal signs of fundamental climate shifts in Antarctica

A steep decline of Antarctic sea ice may mark a long-term transformation in the Southern Ocean, and seawater intrusions beneath the Thwaites Glacier could explain its melting outpacing projections.

By Bob Berwyn | May 20, 2024

https://insideclimatenews.org/news/20052024/antarctica-fundamental-cli
mate-shifts-studies/

Antarctica’s vast ice fields and the floating sea ice surrounding the continent are Earth’s biggest heat shields, bouncing solar radiation away from the planet, but two studies released today show how global warming is encroaching even on the sunlight reflector in the coldest region on the planet.

Research by scientists with the British Antarctic Survey focused on last year’s dizzying sea ice decline. During the austral winter of 2023, Antarctic sea ice extent was about 770,000 square miles below average, an area bigger than Alaska.

Lead author Rachel Diamond said the modeling study showed that such an extreme decline would be a one-in-2,000-years event without climate change, “which tells us that the event was very extreme,” she said. “Anything less than one-in-100 is considered exceptionally unlikely.”

In a separate paper, another team of scientists documented how strong tides push seawater surprisingly far beneath the tongue of the Thwaites Glacier in West Antarctica, reinforcing concerns about the glacier’s melt speeding up and adding to sea level rise.

“Pressurized seawater intrusions will induce vigorous melt of grounded ice over kilometers, making the glacier more vulnerable to ocean warming, and increasing the projections of ice mass loss,” the authors wrote in the paper, published in the Proceedings of the National Academy of Sciences.

“The worry is that we are underestimating the speed that the glacier is changing, which would be devastating for coastal communities around the world,” said coauthor Christine Dow, professor in the Faculty of Environment at the University of Waterloo in Ontario, Canada.

Economic damage from climate change six times worse than thought

A 1C increase in global temperature leads to a 12% decline in world gross domestic product (GDP), the researchers found, a far higher estimate than that of previous analyses. The world has already warmed by more than 1C (1.8F) since pre-industrial times and many climate scientists predict a 3C (5.4F) rise will occur by the end of this century due to the ongoing burning of fossil fuels, a scenario that the new working paper, yet to be peer-reviewed, states will come with an enormous economic cost. https://www.nber.org/papers/w32450

A 3C temperature increase will cause “precipitous declines in output, capital and consumption that exceed 50% by 2100” the paper states.

Electricity production from renewable sources increased by 11.4% y-o-y at 320.0 TWh in February 2024.

Electricity generation from fossil fuels amounted to 397.3 TWh in February 2024, exhibiting a decline of 5.2% (equivalent to 21.8 TWh) compared to February 2023. The reduction is largely driven by lower electricity output from coal. Use of coal experienced an 8.3% year-on-year decrease, followed by gas with a decrease of 3.3% year-on-year. The decrease in coal-fired electricity generation was evident across all OECD regions, with OECD Europe experiencing the most significant decline at 20.3% year-on-year, followed by OECD Asia Oceania at 4.0% year-on-year and the OECD Americas at 3.3% year-on-year. The drop in natural gas electricity production was observed in OECD Europe (-26.4% y-o-y) and OECD Asia Oceania (-3.5% y-o-y), whereas the OECD Americas witnessed a 5.9% y-o-y increase. Overall, fossil fuels accounted for 45.7% of the electricity mix.

The White House on Tuesday will announce steps to modernize a major roadblock to the clean energy transformation: America’s aging electrical infrastructure.

The new initiative between the feds and 21 states aims to make faster fixes and improvements to the grid, committing to build a bigger and more modern grid as part of a larger effort to reduce power outages and increase electrical transmission capacity – a massive hurdle to getting more clean energy on the grid and reducing the planet-warming pollution causing the climate crisis.

Wait.

Wasn't $7 billion just spent on improving EV charging?

Just in general, if we'll be facing hotter and more extreme weather, we SHOULD be upgrading our grid, making it easier to shuttle electricity from one region to another, more efficient (less line losses) and safer, more resilient to storms and able to isolate outages quickly.

Starting with EV charging stations ... and spending about a billion dollars on each location ... seems bass akwards. But I'll bet SOMEBODY made a metric crap ton of money!

So, when is DC gonna get off their various hobby- horses and pork- barrel "solutions" to global climate change, and get serious about this?

Or are they gonna keep spending hundreds of billions on wars of choice?

How much has the USA spent on nukes and delivery vehicles and preparation for all-out war, without any achievements since Aug 6, 1945 – Aug 9, 1945? About $34 trillion (adjusted for inflation and including the time cost of money) which is approximately the size of the National Debt. This year's "defense" budget plus the Veterans Administration budget ($369.3 billion) will be over $1 trillion.
