Climate continues to change.

A localized weather anonomly five years ago is in climate change when it supports Phro's religion.

Pretty powerful politician with a the ability to alter "climate" globally and retroactively. Don't you dullards ever get tired of embarrassing yourselves?

What is cool here and might have been missed is the steel industry working towards hydrogen based steel instead of carbon.

Only as far as possible fuel sources. It still takes a certain amount of carbon to get the metallurgy correct in the production.
 
^^^^ Look at that...the amt of 2019 ice is less than min/max of 10 year average for 5 out of the last 7 months. Sure, there was a slight gain over the last month, but it was still less than average. I bet you would only expect that if the water was actually warmer maybe? So tell me, what is the probability of likelihood seeing the observations we saw in 2019 assuming the 10 year average is accurate? 1 time out of hundred? 5 times out of hundred? Zero times out of hundred?

More importantly, what we see is sea ice decreases in summer. Who ever would have guessed that? Wow...but it has lines at least. Moron.
 
It's almost always the case that trysail doesn't understand the science information that he posts, and mistakes it for supporting his anti-science agenda.
 
I'm super amused at how Try plays you. He could post literally anything and one of three clowns will show up to say how dumb it is. You know he's laughing at you, right?
 
What ever you say Boomer. I am confident his laughter is a weak attempt to cover his embarrassment.

Zero carbon steel is zero carbon...even in the metallurgy. Amazing the power of Google

Zero carbon is not steel, it's pure iron. Which is not steel. Iron does not have the properties that are desired. It has relatively low tensile strength, it's too malleable and does not have the durability. To get steel you still have to add or subtract carbon to get the correct ratio of iron to carbon. The chemistry of steel doesn't change. It still has to have the carbon in the proper ratio to be to even be considered mild steel.

To say that they can have "zero carbon steel" is at best a misnomer and at worst chemically, scientifically and intellectually dishonest.

What the articles you posted are talking about is changing the FUEL process. The fuel process under the current models tends to produce a considerable amount of CO2 as one of its by-products. What I gather they are talking about is developing a method to reduce that particular by-product. Which is fine. The process has always changed if you read anything about the history of steel and how it is made. Each advancement has changed the quality, quantity and efficiency (thus lowering the cost) for a given amount of material and energy input. When that process becomes cost effective enough to produce steel in the quantities required and at a reasonable price point then it will become industry norm.

The articles are about PROCESS. Not the actual chemical nature of steel in and of itself.

No it is not. Coke is used in steel to reduce the iron into pig iron. During the process, some of the carbon is picked up and retained. However, there are other ways to reduce the iron. This is chem 121. Steel is made from pig iron by injecting oxygen to blow off the carbon. Of course, if the iron is already reduced, you dont need the last step...you can go right into making alloys directly. If you had read the second link, this is thoroughly described.
 
Direct quote:

"The production of pig iron, which is later made into crude steel, uses iron ore as a basic material together with what is referred to as a reducing agent, which removes oxygen from the iron ore. Traditional pig iron manufacturing processes usually use coke as a reducing agent. However, in doing so carbon and oxygen produce the climate-damaging gas carbon dioxide.

The aforementioned new production process uses hydrogen instead of coke, which also reacts with the oxygen in the iron ore, but the result is water vapour rather than carbon dioxide. The hydrogen itself is produced climate-neutrally with electricity from renewables. As such, the process could ultimately produce genuinely ‘green steel’."

Edit: paragraphs 4 and 5 of the article highlighted by the second link. Now if what the steel industry is calling steel, isnt steel...who is that on? The greenhouse gases that are problematic are produced in the reduction phase of the process.

Sorry stumpy, but yes it is.

A36 (ASTM spec for mild steel) contains .25% to .29% carbon.
The 4140 QT I just built some loader bucket pins out of has .43% carbon.
If it doesn't have carbon, it ain't steel stumpy. Fact.
Too much carbon, and it is brittle. Blast furnaces, take the carbon out of the iron.
Huh....maybe why it's called low and just carbon steel and carbon steel alloys?

Yes, stumpy, it is the process that creates the most carbon, but steel, still contains carbon. That was his point, that you seemed to miss.

It's the process......now give it a rest.
 
You liberal fuckshits just don't get it, Americans will never believe scientists because we as Americans know better than them. We know when it's hot out and we know when it's cold out. When have scientists ever been right about anything? Blood lettings? Burning women because they thought they were witches? Scientists aren't even sure that gravity is real and insist it's just a theory.

High carbon steel is high carbon steel for a reason. It is needed in springs and takes an edge well.

Modern steel is already lower in carbon than the steel blacksmiths traditionally worked with

Also: why would low or no <sic> carbon steel be desirable to the faithful? Carbon IN the steel is carbon OUT of the atmosphere permanently.

. . .and SOME of that carbon ends up IN the steel. Which is good for the steel.
 
Jesus fucking christ. High carbon steel is not the only kind of steel.

The carbon that produces carbon dioxide is a result of the reduction phase of the process. Period. You can deny this all you want. Doesnt change chemistry.

Of course stupid people dont believe scientists. They are stupid for a reason. Doesnt change anything.

Edit...dumbed it down more for our less capable friends

The steel industry alone accounts for at least 6% of all greenhouse gases. ( see prior links for data). If that is eliminated by this new process....is that not a good thing? Of course...it is still cheaper to buy our steel from china even w tariffs...which have already said they are transitioning away from the CO2 producing reduction process. Why would they do that?

Climategate: Utangling Myth and Reality Ten Years After

"...Climategate did not arise from a few emails being taken “out of context”. It was exactly the opposite. The emails provided behind-the-scenes and very disquieting context for troubling statistical and scientific practices which had, for the most part, already been identified by us and others in published articles in scientific journals and blogs.The contemporary whitewashing and ultimate sanitization by climate academics is itself an interesting and mostly untold story. Climategate exposed bad practices; the fake inquiries whitewashed them, and now the story is being retold so the villains are not only innocent but are to be embraced as heroes..."
