OSLO (Reuters) - An accelerating thaw of Antarctica has pushed up world sea levels by almost a centimeter since the early 1990s in a risk for coasts from Pacific islands to Florida, an international team of scientists said on Thursday.
========================================
Trump denies the effects of climate change but asked permission to build a sea wall at one of his gold courses in Scotland or Ireland to mitigate damage from rising water caused by climate change. Hypocrite.

That the sea level is raising is not a effect of CO2 based climate change.
The Sea level has been increasing at the same rate for many decades before the CO2 levels started increasing.

From the link:

". . . Most ice was being lost from West Antarctica and the Antarctic Peninsula, where warmer ocean water is melting floating ice shelves at the end of glaciers, allowing ice pent up on land to slide faster toward the sea, the study said. . . ."

That's where the volcanoes are. This is a matter of geology, not climate.

[h=2]Panic time: a tiny 0.01% of Antarctica, resting on volcanoes, melts five times faster than nothing[/h]
Let this go down as a prime example of Big Meaningless Numbers used to scare you:
Antarctica’s ice melts five times faster than usual Ben Webster – The Times (copied at The Australian)
Antarctica has lost an area of ice the size of Greater London since 2010 as warmer ocean water erodes its floating edge, a study has found. Overall about 1,463 sq km of Antarctica’s underwater ice melted between 2010 and 2016.
What does 1,463 fewer square kilometers of ice mean?
The findings suggest that melting glaciers on the continent could add significantly to long-term sea level rises, with severe implications for thousands of coastal towns and cities.
Your house might wash away. Or not. How close to zero can a number be and still be “a number”?
The total area of Antarctic sea ice averages about 11 million square kilometers. So that’s one part in 7,500 that melted or 0.013%. But volume is what matters and the percentage of volume that melted is even smaller. Let’s assume ice volume was lost to a depth of one kilometer (the depth of the “grounding line” where the ice-sheet meets the earth). The giant Antarctic Ice Sheet [...]

Run for the hills!!! A whole centimeter over 30 years!!! The volcanoes might melt some more as well!!!

Although most of the ice that has melted was ice shelf. Floating ice so did not actually cause any sea level change but why reduce the panic at all?
 
It's always interesting to see what the the IPCC says.

13.4.4.1 Surface Mass Balance Change
Because the ice loss from Antarctica due to surface melt and runoff is about 1% of
the total mass gain from snowfall, most ice loss occurs through solid ice discharge
into the ocean. In the 21st century, ablation is projected to remain small on the
Antarctic ice sheet because low surface temperatures inhibit surface melting, except
near the coast and on the Antarctic Peninsula, and meltwater and rain continue to
freeze in the snowpack ... Projections of Antarctic SMB changes over the 21st century
thus indicate a negative contribution to sea level because of the projected widespread
increase in snowfall associated with warming air temperatures ...

That's right, the IPCC's AR5 says that Antarctica is gaining ice and will not
contribute to sea level rise this century.

So the next time you read in the popular press that Antarctica is melting
and could cause multi-meter sea level rise, you can pretty well dismiss
it out of hand.

Oh dear. You don't know what surface mass balance means, do you? :lamo

Perhaps you should read more than one chapter or a handful of sentences from the IPCC's report (click on the . Hell, the policymakers summary alone is some 14000 words long.
  • Key Statement from the report you cited:
    • "Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia. The atmosphere and ocean have warmed, the amounts of snow and ice have diminished, sea level has risen, and the concentrations of greenhouse gases have increased."
  • Other statements from the same report:
    • "Earth has been in radiative imbalance, with more energy from the sun entering than exiting the top of the atmosphere, since at least circa 1970."
    • See "Detection and Attribution" attached image
    • See "Anthropogenic" attached image
    • "Human influence on the system is clear."
    • "Some regions will become Century more wetter and others become more drier. Extreme precipitation events over wet tropical regions will very likely become more intense and more frequent."
    • "Arctic will be nearly ice-free by the end of the 21stcentury."
    • "Ocean will be more acidic by the end of the 21st century."
    • "Limiting climate change will require substantial and sustained reductions of greenhouse gas emissions."
  • From the policymakers' summary:
    • "Anthropogenic greenhouse gas emissions have increased since the pre-industrial era, driven largely by economic and population growth, and are now higher than ever. This has led to atmospheric concentrations of carbon dioxide, methane and nitrous oxide that are unprecedented in at least the last 800,000 years. Their effects, together with those of other anthropogenic drivers,have been detected throughout the climate system and are extremely likely to have been the dominant cause of the observed warming since the mid-20th century."
    • "Changes in many extreme weather and climate events have been observed since about 1950. Some of these changes have been linked to human influences, including a decrease in cold temperature extremes, an increase in warm temperature extremes, an increase in extreme high sea levels and an increase in the number of heavy precipitation events in a number of regions."

So lets all chip in and cool the earth so billionairs ocean front property will be saved... is that about where the argument is right now? Building on the coast does not guarantee you eternally static water levels. It's didn't work for Atlantis, and it won't work for Mr. Big Bucks Holding Company, either.

  • I have no idea why you posted that link in response to my remarks. You provide no remarks of your own that indicate what be your rhetorical purpose for posting the link in reply to my earlier comments.

It is self-explanatory, and is the best brief takedown of IPCC BS I have seen.

A centimeter of rise since the early 90's? What happened to all the ice will be gone by 2000?

The wall Trump and others asked to be built addressed a current problem, not some pie in the sky crisis to be named later.

Nobody said all the ice would be gone by 2000. That must have been the voices in your head.

In the years 2007, 2008, and 2009, Al Gore made statements about the possibility of a complete lack of summer sea ice in the Arctic by as early as 2013. While Gore attributed these predictions to scientists, they stemmed from a selective reading of aggressive estimates regarding future melting.

Roughly 40% of the world's population live in coastal areas. It's not just the rich who are affected.


Building on the coast does not guarantee you eternally static water levels. It's didn't work for Atlantis, and it won't work for Mr. Big Bucks Holding Company, either.
So on that basis, we should continue polluting? That doesn't add up.
