Tuvalu gains land mass

The Pacific nation of Tuvalu—long seen as a prime candidate to disappear as climate change forces up sea levels—is actually growing in size, new research shows.

A University of Auckland study examined changes in the geography of Tuvalu's nine atolls and 101 reef islands between 1971 and 2014, using aerial photographs and satellite imagery.

It found eight of the atolls and almost three-quarters of the islands grew during the study period, lifting Tuvalu's total land area by 2.9 percent, even though sea levels in the country rose at twice the global average.


Co-author Paul Kench said the research, published Friday in the journal Nature Communications, challenged the assumption that low-lying island nations would be swamped as the sea rose.

"We tend to think of Pacific atolls as static landforms that will simply be inundated as sea levels rise, but there is growing evidence these islands are geologically dynamic and are constantly changing," he said.

"The study findings may seem counter-intuitive, given that (the) sea level has been rising in the region over the past half century, but the dominant mode of change over that time on Tuvalu has been expansion, not erosion."

It found factors such as wave patterns and sediment dumped by storms could offset the erosion caused by rising water levels.

Cool, another climate change thread. Is this like some sort of fetish for a lot of you? Bringing up a topic that you know you're not going to change anyone's mind on? This goes for both sides of this black hole argument.

Until this stops: http://www.worldometers.info/world-population/ you can reduce carbon or whatever anyone thinks is causing a problem in this world and it really won't matter at some point in the future. Call it Malthusian or whatever, but the hockey stick in that link is probably more important than any other data line.

If it takes 200 years, 2,000 years, 20,000 years, I'm not sure what difference it makes taking a line from Hillary. Without population controls/limits, this all ends rather nasty. Not necessarily extinction, but massive population losses will need to occur at some point to keep us humans going.

Yes

40 years, the sea level hasn't changed at the same places I've gone to.

How's that?


My guess is your eyes are unable to tell the change as it's small


"My guess" is that the sea level change is so small, that's why it can't be seen. Thanks for admitting that the hoax about sea level change is just that, a hoax by the alarmists, and so small, it's unmeasurable.

Is NYC underwater yet?

compared to the changes due to tidal forces.


Who said anything about tidal changes? Further up the thread it made references to changes in water levels due to wind, and the erosion that came from it, not tidal changes.

Sea levels aren't.


Sea Levels have been rising ever since the last ice age ended.

The prediction models have been way off. The actual measurements show not much happening, as a global average.

I did. If you're trying to measure sea change with the naked eye, you have to account for tidal forces. Not sure how one would be able to do this.

Which is why we have scientists who actually use tools to measure sea level and don't rely on their eyes.

Exactly. And their direct observations are contrary to the computer models. See the Telegraph article for more.

Great, so now we can add wind, causing higher water along with tidal changes, which caused the erosion and disappearance of those islands.

Makes perfect sense, thanks for clarifying that.

The Alarmists aren't going to be happy though, how can they blame the disappearing islands on melting ice? Their narrative was just wrecked, again.

I don't think you are understanding the point. It's not that tidal forces have changed over time. It's that in order to measure a difference in sea levels, you have to have a baseline to measure against. But the baseline sea level changes due to tidal forces so you and your naked eye will never know what the baseline is that you are measuring against, and will never be able to tell if it has risen or fallen.

It's global warming! It's evaporating the ocean!!!

Do you suppose that since science can measure gravity waves from a billion light years away they just might be able to figure out how to compensate for tides in their measurements of sea levels?
