Can you show us that this is happening? and like many on the global warming alarmist side, will you use 1975-1982 as a benchmark for making any assertions that we are seeing a major meltoff? I merely ask because this was a relatively cold period that for some unknown (haha) reason ends up being the point of comparison. So we take a 30% relatively colder period and then say things are 30% warmer now with 30% more ice melt now and that proves what exactly? That we are back at Point 0 for averages?
I have heard the ice cap is melting in Greenland but it would still take hundreds of years to completely clear.
I don't pretend to be up to date on the minutiae.
I agree that sea levels rising is not the major issue due to the above fact, storm surges from more powerful weather systems are a much bigger concern currently.
I also agree completely that any conclusion can be skewed by choosing what is the start point and what is the end point. It's something that most journalists and reporters seem to ignore completely, being the dumbed down copy pasters that most of them are these days.
Still if the scientists who study this say we have experienced significant faster warming since CO2 levels increased, then I am going to sit up and take notice. There is also the acidification issue in play.
I'm with finley mostly though as I think we need to deal with particulate pollution as a priority, being forced to live under it for much of the year in Taiwan and China and elsewhere.
