We'll have to wait and find out, I guess. There is so much potential energy stored in very complex systems, and the stored energy is becoming greater. I don't know what the outcome will be. I suspect recent extreme weather conditions may be an indication of future weather that could only get much worse.

"He said 57 percent of climate scientists “don’t buy off on the idea that CO2 is the knob that’s turning the climate.” This is based on a flawed reading of a survey of 1,868 scientists; one of that survey’s authors has called Santorum’s claim “absolutely false.”

He called the oft-cited 97 percent consensus figure “bogus,” and said it was based on a survey of only 77 scientists. In fact, several surveys involving thousands of researchers have all found that the level of consensus that human activity is primarily responsible for warming is as high as 97 percent.

Factcheck.org? A fancy name doesn't equal credible. Every time you get challenged you ignore the challenge, change the subject, or post some more propaganda. How about you share some of your own thoughts beyond your canned "we will see" response.

Consensus is not science. 97% or more of scientists can be, and have been, wrong on several occasions. Of course, despite the blurbs from that joke of a fact checking site you quoted the percentage of climate experts that agree with the theory of anthropogenic global warming is not anywhere close to 97%.

 

[TugboatEng]

I got booted out of the pub and banned from Nextdoor for daring to observe that COVID vaccines did not prevent infection.

The consensus was wrong.

 

[BridgeSmith]

I got booted from the pub due my unpopular political views, mostly regarding racial issues.

 

[GregLocock]

The 97% figure is extremely dodgy.

Here's how they got it.

Based on reading abstracts discarding all those that made no judgement of human causes (66%)
Of the remaining 34% 33% thought humans contributed (to some extent) to global warming.

33%/34%= 97%

Tada.

And you fell for it. Because it suits your agenda.



Cheers

BridgeSmith and TugboatEng,

You both were booted from the Pub because some there support censorship. If you wish, ask management to be readmitted. I sense that censorship is not quite as prevalent now.

I've never been booted out of any pub ... just saying, didn't realise it was a badge of honour.

It's not the heat that gets you, it's the humidity... This summer could be interesting with the ENSO.

"According to official data, heat claimed almost 300 Australian lives and sent 7,000 people to hospital in the past decade.
But an Australian National University study argues the true numbers are vastly under-reported because death certificates only record certain information. It found heat had contributed to 36,000 Australian deaths between 2006 and 2017."

Wind turbines in wood...

“From the outside, there is little obvious difference between the Modvion wooden turbine and its steel cousins.
Both have a thick white coating to protect them from the elements and blades made primarily from fibreglass attached to a generator, which produces electricity when it turns.
It is only when we go inside the tower that the differences becomes clear. The walls have a curved raw wood finish, not unlike a sauna.”

This is hilarious. There is a thread in the hobby forum complaining about the high cost of wood due to lack of availability. The forests can't keep up with demand. Maybe we should fertilize them? Oh wait, there is a urea shortage too? As climate change causes forest fires, apparently, there won't even be forests to build these turbines. A 500 foot tall structure to make 2MW of power? What a waste.

Dik, you should be mindful of what you post here. We're smarter than your average climate alarmist. You aren't helping your cause posting such ridiculous stories.

 

[TugboatEng]

Hokie, I guess I'll stay out. This forum is too valuable to
risk losing because a few people don't like my observations.

 

[hokie66]

Your choice, but there are times when your input in the Pub would be appreciated. Dik's climate alarmist forum is best avoided.

I wonder at times and sometimes have to give my head a shake...

Carbon footprints of common building material:

https://pliteq.com/news/building-vs-carbon-footprint/

1. Rammed Earth - With an average of 48kg embodied carbon per m³.
2. Softwood Timber - Softwood timber emits on average 110kg embodied carbon per m³.
3. Cross Laminated Timber - Averaging about 219kg embodied carbon per m³ in emission.
4. Stone - Stone emits about 237kg embodied carbon per m³.
5. Clay Brick Wall - Averaging on 345kg embodied carbon per m³.
6. Reinforced Concrete - With an average of 635kg embodied carbon per m³.
7. Glass - Glass on average produces 3600kg embodied carbon per m³.
8. Steel Section - Steel carries on average 12090kg of embodied carbon per m³.
9. Aluminum - Aluminum brings on 18009kg of embodied carbon per m³ on average.

Plastics for the blades are likely down near the bottom of the list... not included as a common building material. Take a look at the earlier chart showing the growth in use of wind turbines.

[TugboatEng]

It's entirely worthless to compare carbon per m3 of various building materials without comparing the m3 required to construct. The image in your article shows a wooden structure with a wall thickness of ~18 inches where the same structure in steel would be ~1/4 inch.

How does that affect your interpretation of your data?

 

[dik]

I just read that into the numbers... knowing that the steel project will use far less steel than the concrete one... I've not been able to come across values for completed projects as a cost per square foot (in carbon values, or something relevant).

There is a reason those studies don't exist.

It'll be curious to see what the end of 2024 is like... more of the same, or worse?

California just banned portable chainsaws so expect our wildfire season to get substantially worse, all in the name of climate change.
