Melting is taking place where there is no geothermal heating. The destabiliation of the WAIS ice shelf is due to warm ocean water melting it from below. That water is not being warmed by volcanos. The volcanos found under the WAIS may be accelerating the sheet's movement to the sea, but multiple studies have concluded their effect is minimal and the largest factor in that acceleration is the loss of the shelf that had been blocking the sheet's movement off the coast. And, as the OP's linked study tells us, the geological record indicates that at no time in the past 45 million years has Antarctica been able to support an ice shelf with CO2 above 400 ppmThe main cause of todays localized melting is due to active Volcanoes which you and other warmist/alarmist loons ignore continually as it has been posted in this forum many times.
And set a new all time high back in March, 37.2 degrees Centigrade (67F) warmer than usual. That would make a cool 70 degree spring day 137 degrees.The region as a whole is simply too cold to melt much of any on the surface and the Continent whole continent just endured the COLDEST summer then winter on record last year.
South Pole froze over in coldest winter on record
You need to drop this stupid infatuation of a feeble trace gas with negligible warm forcing effect at the 400-ppm level as most of it was already done in the first 100 pm level thus any additional CO2 at the 430 level is simply negligible.
You are probably the most snookered warmist/alarmist in the forum.
