There is no "study that promotes alarmism", if there were, I would have a good look at it and if it did not fit the mainstream, I would largely ignore it unless some one brings it up.
Deniers here are allarmist when they claim that the science is a hoax and that it is a tax grab or that we all have to live in caves.
Global warmers would be people who want the global temperature to be warmer. Other then Kano, I can not recall any one advocating for a warmer globe.
You didn't provide a link to the quote, (quite typical of people with a hidden agenda) so let me provide the first one the search showed up. [1]
If Zwally’s study is correct, it raises another question: Where did the sea level rise attributed to Antarctic ice melt originate?
In recent decades, the world’s oceans have risen an average of 2.8 millimeters (0.11 inch) per year, according to a 2013 report by the IPCC. That rise is attributed to Antarctic and Greenland ice sheets melting, to disappearing glaciers and to thermal expansion — when heat from climate change causes the ocean to expand, therefore causing a sea level rise.
“The good news is that Antarctica is not currently contributing to sea level rise, but is taking 0.23 mm per year away,” Zwally said last week in a press release.
“But this is also bad news,” he said. “If the 0.27 mm per year of sea level rise attributed to Antarctica in the IPCC report is not really coming from Antarctica, there must be some other contribution to sea level rise that is not accounted for.”
