New Evidence of Global Warming

It keeps getting more difficult for climate change deniers to explain away all the evidence. A new NASA study shows how warm ocean currents are responsible for the majority of melting of Antarctic ice. Ice floating in the oceans around Antarctica is reducing in both extent and thickness. We have very good measurements of this using both radar and laser altimeter. Most of these measurements were made by instruments on ICESat, which flew between 2003 and 2009. ICESat 2 is scheduled to be launched in 2016. I'm sure it will be startling to compare the measurements of the second mission to the measurements of the first one with a gap of over seven years. Will we see the thinning continue? Or, will we see it reverse itself and get thicker? ICESat isn't the only way we have of measuring ice cover and those missions are showing the thinning trend continues.

The study showed that the ice is getting a double whammy. Warm air from global warming is melting it from above and warm currents are melting it from below.

So, explain to me how it is that both the air and ocean around Antarctica are getting warmer if we are not experience global warming? The scientific data is there. Any contrary explanation must take it into account. I am willing to post any explanation for this data that opposing viewpoints might propose. Just send it to me.

The silence is deafening.
