Climate Change Denier comes in from the cold: SCIENCE!!!

You are an idiot.

Who was the lecturer? What was the topic? In what contexts was Gaia mentioned? Is this true?

Are you really this stupid?

You don't come right out and say it, but this implies that you believe that sea level rise will be the same everywhere (ignoring tides, storms, etc.). Likely you don't believe that since you live on an island continent where 85% of the population lives within 30 miles of the ocean, your member name is Dredge, and your avatar is a lake/harbor dredge.Anyway, whatever you believe, here's some information. The ocean is not just a giant swimming pool with the level the same all around the pool. There are a lot of factors at work.You probably already know tidal changes are not the same everywhere. As you travel a coastline the magnitude of the tidal change can vary enormously, governed by a number of factors. Some parts of the world have very small tides, like the Mediterranean and the Caribbean, while the Bay of Fundy's tide change is about 38 feet.Like tides, the amount of sea level rise will vary widely around the world. Ignoring lunar tidal influences, sea levels around the world vary according to currents, temperature, saltiness and land configuration. Because of these factors some coastlines will experience greater sea level rise than others. NOAA ( National Oceanic and Atmospheric Administration) projects that the US coastline will experience sea level rise that averages 10-12 inches in the next 30 years, varying regionally (see Projections through 2150 for all U.S. coastal waters). And at Sea Level Rise Technical Report the NOAA explains why sea level rise varies around the world:

The first driver, stereodynamic sea level change, refers to changes in the ocean’s movement (circulation and currents) and its climate (temperature and saltiness). Trade winds and currents can push water higher, or lower, in different regions. Freshwater added from melting ice sheets and glaciers can shift ocean circulation patterns in different regions by changing the saltiness, temperature, and density of the water.
...
Changes in land ice and solid Earth – also called gravitational, rotational, and deformational changes – can also affect regional sea level. When ice sheets and glaciers melt or lose mass, this adds freshwater to the oceans and changes the gravity, deformation, and rotation of the Earth, which then contributes to higher sea level rise at locations farther away from the ice melting source than locations close by. These patterns of sea level rise are known as “fingerprints” and are the reason that ice mass loss from distant Antarctica will impact the U.S. coastline more so than ice mass loss from Greenland.

Tuvalu is only one of the more dramatic examples and definitely not the sole victim of climate change that has been written about. Here's a brief report on how Woodbridge, a coastal community in New Jersey, is dealing with sea level rise with a home buy-back program. This from my Message 62 in the Who's the bigger offender: Conservatives or Liberals? thread from last year: Even if Tuvalu didn't exist, even if there were no low lying oceanic island complexes, it wouldn't change the fact of sea level rise. It's not possible you don't know about the amount of water and ice flowing into the ocean from glaciers around the world, mostly in Greenland and Antarctica. Sea level cannot help but rise. Rising and falling sea levels have happened many times in geologic history. Around 18,000 years ago you could walk from Asia to Australia.--Percy

Over half the sea level rise during the past 25 years is due to thermal expansion. This component of SLR is projected to increase to over 70% in the future. The oceans are heating up rapidly.

I found sites on the Internet that also said this, and I found a link to an IPCC report where the claim originates: Climate Change 2007This motivated me to do a little math. Average ocean depth is 2.29 miles, and at 50 degrees a 1°F increase in temperature causes a .00899% increase in volume (for pure water, couldn't find a figure for ocean water), which causes a 4.35 inch rise in ocean level, assuming vertical shorelines instead of the actual sloping ones. Surface ocean temperatures are supposed to rise around 2°F by 2050, so the accompanying estimated 1 foot rise seems right in the ballpark, with around 9 inches from thermal expansion of water and 3 inches from melting ice.All of Greenland's ice melting would cause a 21 foot increase in sea level, and Antarctica's would add maybe another 200 feet, and the rest of the world's ice maybe 15 more feet, but we know sea levels have changed hundreds of feet in the past. Even though thermal expansion of water is a currently a significant contributor to sea level rise, that can't be true in the long term because a hundred degree change in water temperature is only 36 feet. So I assume the geologic uplift and subsidence were also contributors.--Percy

Edited by Percy, : Mistakenly said "feet" instead of "meters" in part of last paragraph, so I've fixed it and rewritten the latter part of the paragraph to make sense in light of the new figures.

The great flud(s)?

From memory, I think the Antarctic ice is good for about 70 meters (200 feet)

Thanks, I was reading meters and thinking feet. I'm going to fix my post.--Percy

When you read "meters", think "yards". Should be close enough.Part of a page I'm working on for my website, "How to Learn to Think in Metric".

According to research I did back when and posted on CompuServe in 1990 (GEOLOGICAL EVIDENCE OF AN ANCIENT EARTH), the melting of the ice sheet at the end of the last ice age, the Wisconsinan Ice Age:

As promised earlier:

​

      Question: "Is there any evidence of a single world-wide flood?"
      Answer: "YES, and it is still going on!"

​

During the ice ages, the sea level would subside due to the amount of water that would be trapped in the ice caps rather than being in the oceans. During the last great ice age, the Wisconsinan, the sea level was about 200 feet lower than it is now. This means that ocean bottom shallower than 200 feet was dry land and a number of land bridges, such as the one across the Bering Strait were open. Judging from my atlas, most of the Persian Gulf should have been dry land.

​

Then about 11,000 to 17,000 years ago, the Wisconsinan Ice Age ended, the ice melted, and the sea level rose, flooding the lowlands. Since human populations tend to concentrate along the shorelines and in the lowlands, this catastrophic flooding could not have gone unnoticed. Indeed, it would be very surprising NOT to encounter flood stories world-wide.

​

So not only do we have here an example of a single world-wide flood produced entirely by natural causes, but it is still going on; the flood waters have not subsided! Indeed, if the world climate warms up as we fear it will, then we would be faced with still worse flooding as the sea level rises another 150 feet (if the entire Antarctic ice cap were to melt).

ABE:
So we are still in the middle of that world-wide flood; the waters have not receded! And now the "flood waters" are getting even higher.Since then, I learned of the Wallace Line in Indonesia:

quote

---

The Wallace Line or Wallace's Line is a faunal boundary line drawn in 1859 by the British naturalist Alfred Russel Wallace and named by English biologist Thomas Henry Huxley that separates the biogeographical realms of Asia and Wallacea, a transitional zone between Asia and Australia. West of the line are found organisms related to Asiatic species; to the east, a mixture of species of Asian and Australian origin is present. Wallace noticed this clear division during his travels through the East Indies in the 19th century.

​

The line runs through Indonesia, between Borneo and Sulawesi (Celebes), and through the Lombok Strait between Bali and Lombok.

---

Using Google Earth (which also displays sea depth), I found the depths of the Java Sea to be under 200 feet, similar to the depth of the Persian Gulf, which would be indicative of a land bridge during the Wisconsin Ice Age. However, between Bali and Lombok (through which the Wallace Line runs) sea depth is 2000 to 3000 feet deep, hence no land bridge for there. Same between Borneo and Sulawesi (about 5000 feet deep).Also, on a "Discovery"-type channel, they reported about an ancient sea-side temple complex somewhere on the coast of India. It stands there half submerged about a quarter mile out from shore (if I recall correctly).

Oh, I get it - you have next to nothing to offer as evidence that rising sea levels are problematic, so you've resorted to trying to change the subject.If "global warming" were causing alarming rises in sea levels, two countries especially would be screaming blue bloody murder - the Netherlands and Bangladesh. But what do we hear from them? Sweet bugger-all.

Dredge, I know you are just a troll trying to have some fun with us, but this 2017 NYT article might interest you. It reads in part: I guess "screaming blue bloody murder" is an Australian thing. Others use their ingenuity to deal with reality.

Having grown up in Australia, I guess I'll come to their defense. They recently voted out their previous government (which seemed to think like Dredge). And global warming was one of the major issues in that election.
