Science Discussion

[McLeansvilleAppFan]

Can I mute a topic? I don’t care to be “educated” on YC.

Just don't read it. I don't read every post and thread on YC. It can be done.

Ah, YC Left. Always bringing their “knowledge” to the unwashed masses.

Thinking that science is left or right is pure projection on the part of someone saying that. If those that study the hard sciences are to the left of some on the YC it may be due to them having studied with an unbiased eye and realized certain policies should be in place due to what they have learned.

I am literally just asking some basic science questions that relate to climate change. Not everyone has time to read all of this, but to just shut it out behind slogans of "unwashed masses" and one's own political projections is a bit sad coming from people that are educated with a degree from App State. God forbid some people learn a few things in life, especially on important topics.

Again no one is forced to read this thread.

What about the water? I need a bit more details. (I know you are trying to take the piss out of me, but I will play it straight.)

More water?

That is a common misconception and the reason I asked this question first. Most everyone things the melting ice is the reason sea levels are rising but that is not the MAIN reason. Ice melt putting more water in the oceans is indeed part of the reason but there is more to it than that.

Thermal expansion occurs with the water. When things increase their temperature they increase in volume. The water just takes up more space due to higher temperatures. From what I have read from various sources thermal expansion is about 55-60% of the cause of rising sea levels and the increased amount of water due to melting ice is the other part of it. Of course the recently melted water is also going to go through thermal expansion.

I’m no physics teacher but I pretty much took every physics class offered at App that didn’t require advanced math. Loved physics, not good at math. But I credit physics with being the best thing that happened to me at App. It taught me how the reason and problem solve. And if there is one skill everyone should leave college with it’s problem solving. But when you really think about both the expansion of and the addition to could be considered to be more water.

Earth's one full wobble, which looks like a slowly spinning top, happens every 10,000 to 23,000 years, according to astronomer Milutin Milankovic. In 1976, in a landmark study, it was reported that over the past 80,000 years, carbon dioxide levels fluctuated between about 170 parts per million and 280 ppm. I learned about it in a HS earth science class 35 years ago. You don’t hear about this enough because it’s not sexy and is boring news. Basically, sea level rise is a natural phenomenon perhaps being slightly accelerated by humans. With that said, humans are a cancer to the planet the way we abuse it.

Humans are a cancer. Really?

The way 7 billion people pollute, mine, over do everything, yes to the planet we are diminishing its health, that is as basic as it gets. Cancer is a strong word, but to the planet, yes, we are sickening it with our abuse. I’m not saying pop control, it’s just facts, our species is indeed taking at a faster rate than we can recreate. The question was about sea level rise, I don’t think humans are doing that in full, that’s just a natural phenomenon.

Question 1: What is the largest contributor to sea level ocean rise?

I'm going with a solar flair, volcanic eruption, metorite strike or whatever massive thing happened 12,000 years ago to cause the Younger Dryas at the end of the Pleistocene Epoch, with melting of the Northern Hemisphere ice caps, 3000 ft sea level rise, the origin of all the ancient flood myths, extinction of the megafauna, etc

I don't know that much about the Younger Dryas. but temperatures were a bit cooler then. After Younger Dryas there was some sea level rise (Meltwater Pulse 1B) but that was around 28 meters at most it seems. Still a lot of sea level rise after the Younger Dryas. There is a lot of great climate science in all of this with sea level, amount of ice, albedo effects.

It took more than 28 meter of rise to submerge Doggerland. Some spots are as shallow as 15-30 meters, but much of North Sea is 100 to 200 meters deep, and in excess of 700 meters in some places (though that part might not have been part of Doggerland).

I think most of the sea level rise was at the very tail end of the Younger Dryas (10,000-9,900 BC) when the Earth went from very cold to signficantly warmer and the ice caps receeded.

But I am no expert obviously, and most of my interest in that period isn't climatic. I am more interested in how the humans went from "cavemen" to "civilization" within a few afterward.

I agree, cancer was a strong word.

I agree, cancer was a strong word.

The Oxford dictionary has 2 definitions for cancer, number 2:

a practice or phenomenon perceived to be evil or destructive and hard to contain or eradicate.
"gambling is a cancer sweeping across the nation"

It’s a strong word, but appropriate considering the ramifications. I don’t think people are evil, but I do think we are destructive in regard to our planet. Not trying to argue, just making a point. I hope we start taking better care of this place before it’s too late.

Shawn Clark has devastated our program to the degree that our fans are talking about expert opinions on science. My heavens this is humiliating.

Looking for an answer teach. I think I answered correctly with “more water”. Your question was, “what is the largest contributor to sea level ocean rise”. Above you have described the process that creates more water in our oceans but the process doesn’t create the rise, the addition water creates the rise, “ more water”. I believe the correct measurement would in this case be volume. Melting ice puts “more water” in our oceans by volume and thermal expansion also puts “more water” by volume in our oceans. I would like a ruling.

[spacemonkey]

If we could keep "pre existing conditions" that would solve the more water problem and other problems that arise from getting rid of "pre existing conditions".

One. App Physics is really good. Dr. Connelly wrote a column for years in the The Physics Teacher magazine. Dr. Mamola was the editor for a good many years. That is a BIG honor for him and the department. Some of the editing is still housed at App State. My math is not very good either, and I still don't know how I got through 3 semesters of Calculus and then Differential Equations.

I guess the point I was making about the water is that we would still be seeing sea level rise even if there was not ice melt adding liquid water to the oceans. Just the water we have in place in the ocean basins would expand as the water temperature increased.

Costco and a few gas stations were sued and paid out some money a few years ago and I do think it had to due to thermal expansion. I need to look that up as my memory on this may be off but there was something about volume measurements and energy production from the gas being sold.

Since you back up your original statement with a bit more thought I would give you 75% from the original 50%. I really wanted to see thermal expansion in the answer and I think that was missing in the original reply. I doubt I budge off that but that is a passing grade. Now get off your phone before I take it.

I’m going to appeal to the Dean.

I think I remember Dr. Mamola. That was 38 years ago, was he at App then.

[Stonewall]

I remember Mamola. Otherwise disinterested unless we move on to Biology.

[McLeansvilleAppFan]

Dr. Mamola moved to Portland with his wife to be near a daughter and grandson. He posts a lot on Facebook. I know we honored Dr. Mamola in 2014 when the NC Physics Teachers held a meeting in Boone. He moved to Portland some time after that. The honor may have actually been a national honor.

[McLeansvilleAppFan]

Next Question: Melting ice is part of sea level rise though not the largest contributor. However besides, sea level rise the melting ice could cause a feedback loop that makes global climate change even worse. What is the connection to global climate change and the melting ice at the poles. (I am thinking of one thing in particular but there could be two responses I would take as correct. I am not sure if I am wording this correctly.)

[Bootsy]

Nuclear isn’t as dead as people might think. There is a growing interest in nuclear power for two reasons:

• AI/big data farms are growing and have large power needs that traditional plants struggle to supply

• Nuclear plant technology continues to evolve, with much smaller footprints and safer systems being created/deployed

[Saint3333]

Perhaps the biggest energy mistake that we have made as a nation. Gen 3 and now Gen 4 Nuclear is very safe and long-term power costs are lowest depending on how renewables are calculated (subsidies). Probably why China is building 150 nuclear reactors over the next dozen years. Their power costs will provide them an economic advantage over ours.
