Casting and global warming

[Tenbender]

We have failed to learn from the Martians. The insisted on driving their gas-guzzling SUVs and refused to control CO₂ emissions from all their industries, and look what happened to the atmosphere of their planet. What a shame. I'm sure there were liberal sophisticates in the Martian government and education systems warning of the coming disaster for years, but none of the greedy industrialists or selfish consumers payed any attention.

I bet the USA sent the Mars probe there to steal a set of hub caps off one of those Martian SUV's ?

It was 82 here today, had to open the windows in the house, might have to run the AC tonight. Thank you guys for keeping all that white cold stuff to yourselves.

82 Degrees F?
I currently live in a valley. My home is located on a southwest facing slope about 200 feet above the valley floor. The valley is 900 feet deep.
This creates a micro climate that is measurably warmer in summer and colder most days during the winter.
There have been summers when 80F was a rare event.
The micro climate is such that folks can grow corn and it will mature several weeks prior to the first frost of the year.
On my property 7 miles from my home and less than 5 miles west of the edge of the valley (Property elevation is just under 2000 feet) any day the temperature reaches 75F in the summer is an extremely rare event.

The first missionaries came through here over 200 years ago with the fur trade. All were here to counsel the natives and show them the light of Christianity. All described the fires of Hell. It is really difficult to convince folks living in skin tents and heating those tents with a small fire that eternal flame and heat was a bad thing at temperatures hovering between -30 and -40F. Hell does not have to be hot.
I recall mention of early traders and missionaries recording stories in their journals of folks found frozen to death less than half a mile from warmth and safety.
In the days prior to electricity my father would keep track of an older gentleman who had a cabin two miles away. My father would walk 1/4 mile to a hilltop where the cabin could be seen and look for smoke from the chimney just before sunrise and sunset during the winter. No smoke meant a trip to visit to ensure the gentleman was alive and well. One morning there was no smoke, we went to the home immediately, and discovered the fire had been out all night. The gentleman had a small stroke early the evening before and could get out of bed to keep the fire going. He was alive in bed - the wool quilts he used in the winter were enough to keep him warm. The water in the reservoir on the side of the wood stove had almost an inch of ice on it.
His first words as we came in the door were "Boys, am I ever glad to see you! I thought I was going to die..."

I envy you your warm days...

I do not like to be cynical but I will. I like to think I know something about human nature since it is a key bit of knowledge for the profession I have been successful in for over 30 years.

With that above it is my view this whole "Global Warming" thing is an egregious exaggeration on the part of liberal academics who are trying to gain some recognition with liberal politicians who are eager to make rules/pass laws that just vest more control with government: Creating solutions in search of a problem are their hallmark then we are stuck with the idiocy of their decisions.

Climate change has taken place since the beginning of time and will continue after the human species is long gone.

IMHO

The cold is ..... but I need good ventilation before I cast. Fans blowing , windows open, so really cold stuff doesn't work for me. But it should be warming up this week.

Global warming isnt a liberal thing. Its science. Extreme summers and extreme winters are signs. While the earth does naturally change climate, the fact that we are speeding it up a lot is still a very bad thing for us humans. That people would deny scientific fact for political and monetary gain is the worst kind of ignorance in my opinion.

Do me a favor and read your statement again! "Global warming isnt a liberal thing. Its science. Extreme summers and extreme winters are signs." You cannot even get your definitions right. So your extreme winters are "global warming"? Now all of you idiots have changed it to climate change! Guess what? Right now it is 50 degrees and tomorrow it will be 65. Wow, how did you know my climate would change?

Interesting statement.
I live in an area of the world that was covered by over a mile of ice some 15,000 years ago.
That ice was part of a glacier that covered the north half of North America. There was also a Glacier covering Northern Europe that was just a significant.
There was also a glacier that extended from the south pole into the Atlantic, the Pacific and South America.
Sea levels were some 80 meters lower at that time.
All of this ice melted over a 1200 year (or less) time frame. It melted fast enought that every culture in the world has aural legends of a "great flood". Hey, every one lived on the sea coast where the climate was better and food was more plentiful. But the glaciers did melt fast and the sea levels did rise very quickly - giving rise to the "great flood" legends.

That being said , calculate the volume of ice that the top 80 meters of sea water would produce that was tied up in the glaciers. Consider that 1 calory of heat will warm 1 cc of water 1 degree centigrade. Consider that the latent heat of fusion ( the ammount of heat it takes to break the electron bond of 1 CC (.88 gram of ice) is 84 calories.
So to take ice from -1c to water at +1C will take 86 calories of heat.
When you consider the amount of heat needed to melt the ice from the last glaciation - the energy pouring over the earth (heat energy) must have been astronomical.
There is evidence that the Arctic ocean was ice free 4000 years ago. and that the Perma frost in Northern Europe and Northern Alaska and Canada hass only been permafrost for less than 5000 years.
The global warming idea is a great way to strike fear and get grant money to study climate.
The history of the world shows the earth has been through more extreme climate changes that were not caused by man.

The climate changes - that is a fact. When science tells us why the last ice age melted so quickly then maybe they can tell us how to deal with that amount of heat if it happens again.
BTW: the salinity of the ocean was extremely high up to 12,000 years ago - look at the marine life that survived the dilution of of the oceans because those glaciers melted.
