Three lessons from that Antarctic ice study
Three lessons from that Antarctic ice study
A satellite study that found Antarctica is gaining ice contrasts previous findings.
By Lonnie Shekhtman, Staff November 4, 2015
Research from retired NASA Goddard Space Flight Center scientist H. Jay Zwally made headlines this week for finding that contrary to popular belief Antarctica is gaining more ice than its losing ... for now. But Dr. Zwally warned in a NASA announcement that, It could take only a few decades for the ice melt in Antarctica to outweigh the ice gains. Zwally didnt dispute that sea levels are rising, telling The Christian Science Monitor in an interview, its definitive, theres no question about that." But theyre not rising because of ice melt on Antarctica, he says.
.....snip........Some scientists, like Ted Scambos, senior researcher at the National Snow and Ice Data Center in Boulder, Colo., say that ICESat data is inaccurate.
Theres no real way to reconcile this paper with the finding of half a dozen labs using the GRACE satellite, which consistently indicate that Antarctica is losing mass overall, he points out in an e-mail to the Monitor.
....snip......the lessons~
1.
Measuring land ice in Antarctica is hard........
2.
Sea levels are rising Sea levels are rising at double the rate (3.2 millimeters per year) of the 20th century, UN's Intergovernmental Panel on Climate Change (IPCC) says. And its virtually certain that this trend will continue for many centuries.
Up until this century, ice melt on land has made only a small impact on sea level rise. About two-thirds of it has come from thermal expansion, or ocean thats heating up from a warmer climate and causing the water to expand, according to Julien P. Nicolas, an atmospheric scientist at Ohio State University.....
3. The globe is still warming....
