Yes, you are right. When the sea ice around Antarctica goes, then the ice that is on the peninsula will melt as well which will increase sea levels. BTW, it is also true, despite some people claiming it is not happening, that geothermal and volcanic activity under our oceans is increasing. Heck, we have seen an upsurge in volcanic and geothermal activity also on land. Not to mention the other discoveries made that underwater volcanoes have been indeed melting areas of the Antarctic.

Underwater volcanoes, not climate change, reason behind melting of West Antarctic Ice Sheet

But it has been also happening in the Arctic.




The Gakkel ridge, stretching ,1,800 km across the eastern Arctic Basin, is the ultraslow-spreading end-member of the global mid-ocean ridge (MOR) system, and in 1999 the Global Seismic Network (GSN) detected the largest MOR earthquake swarm ever recorded 6 on the ridge at 85 (degree). Several lines of evidence suggest that the swarm was associated with a major volcanic event 6–10, but our ability to characterize volcanic processes in this region has been lim-ited by its remote location and ice cover.
...
The maximum extent of the pyroclastic material is not known, because the deposits were observed to cover every portion of the sea floor that we surveyed (,20 linear kilometres within an ,5310 km region).
A series of eight dives across the Oden and Loke volcanoes suggests that the ubiquitous cratered volcanoes may be source vents for pyr-oclastic eruptions, possibly including vulcanian explosions. These volcanoes contain most of the fresh lava flows observed in our survey, which consist primarily of pillows but also include ropey sheet flows, covering small areas (,100–200 m^2) on the top and around the outer edges of the constructional features. The mixture of young and old lava flows that we observed demonstrates that the high-acoustic-backscatter region imaged in 1999 does not represent a single, fresh lava flow 8.
...
These results provide a new perspective for interpreting the 1999 seismic swarm and volcanic event at the 85 (degree) site. The seismic swarm began with extensional events, but after three months the earthquakes changed to sources with large volume changes (implosions) 6. Large-volume-change events are rare at MORs, but they are consistent with the rapid evacuation of explosive material from a deep-lying magma chamber.
...
Multiple episodes of explosive volatile dis-charge over a prolonged period are required for producing the variations in apparent age and thickness of the deposits we observed, and we note that small-magnitude explosive acoustic signals were detected by local (ice-mounted) seismic networks at the eruption site more than two years after the 1999 seismic swarm 19. Explosive volatile discharge has clearly been a widespread, and ongoing, process at the 85 (degree) segment.

People seem to forget the earth and everything in it moves in cycles. The planet cools and heats by itself. If humans have any thing to do with it the earth will fix the problem. There is nothing anyone on earth can do to cool the planet. All this was foretold to happen.

the size of Tasmania,


Now that is a measurement tool we use daily lol WTF

Already posted nearly a week ago. And well discussed. It is not a volcano. See Phage's links for a good explanation.

Try using search here too.

As far as i can read Phage made a hypothesis, which doesn't equal to "it cannot be geothermal/volcanic activity." More so when several research papers say the contrary and Phage has been known to claim those research papers do not say so despite the clear statements made in said papers.

Then there is this.

Antarctic sea ice levels hit record low, but experts are not sure why

Scientists discover 91 volcanoes below Antarctic ice sheet

i know the above link does not prove that volcanic/geothermal activity has increased, however it shows that there are more underwater volcanoes in Antarctica than previously thought.

And it's been happening in Greenland. (Yes i know Greenland is to the north, and Antarctica to the south, just showing that there is plenty of evidence showing that there has been an increase in geothermal and volcanic activity pretty much all over the globe.

Not to mention, didn't you read/listened to the claim from Professor James Renwick claiming that this has been caused by atmospheric heat caused by the industrial revolution supposedly transferred the heat down to 1,000 meters+ and the heat somehow transferred again back to the surface within a time frame of less than 165 years, which is simply not possible. The majority of the heat from the atmosphere that has been transferred into the ocean has not reached those depths. It's simply not possible, yet like Phage, Renwick wants to blame mankind and makes up some impossible theory simply because he cannot let go of the AGW claim, just like some other people here.

(there was another thread where I posted several other papers pointing to the fact that geothermal activity, volcanic activity, and even earthquake activity has been increasing worldwide. Trying to find that thread with the links)


edit on 16-10-2017 by ElectricUniverse because: add and correct comment.

Except that the warming the Earth has been experiencing started in the early 1600s, over 250+ years before the height of the industrial revolution.


Except that it didn't. We know that vulcanos caused the little ice age and the temperatures recovered afterwards.
Looking at all the data, we can see the temps slowly adjusting to those of the Medieval warm period over a few centuries. Actually, you're out on a limb to state that this wasn't a recovery but the start of global warming.



As well as the dramatic changes that have been occurring to Earth's magnetic field, and the dramatic changes occurring in the Sun which point to the fact that Earth's interior has also been changing dramatically which would be the reason why Antartica and other regions have been experiencing and increase in geothermal and volcanic activity.


Dramatic changes in the sun should be tangible and I don't see any. Also, vulcanic activities might be increasing but your hypothesis lacks convincing data.

You are the one making the false equivalency claim.


Due to the fact, that the warming during both periods you mentioned isn't really comparable with the one we see now. Yes.

In their attempt to keep trying to blame mankind for all the changes Earth is undergoing, their argument is crumbling in the face of facts.




First, plenty of other posters understoodcwhat I wrote on page 1, but you did not. Perhaps you have a reading comprehension problem.

No one is blaming man for all the changes. To make such a claim is frankly stupid.

Someone else already posted about this. But you had to make your own post where you write AGW is a lie in the OP...kind of low brow on an otherwise good OP.

When someone critcizes you, you are quick to bring out attacks and insults.

We are all wrong sometimes....
