"NASA will host a media teleconference at 1 p.m. EDT Wednesday, Aug. 22, to discuss the upcoming launch of the Ice, Cloud and land Elevation Satellite (ICESat-2), which will fly NASA’s most advanced laser altimeter to measure Earth’s changing ice. The teleconference will stream live on NASA’s website.

ICESat-2 is scheduled to launch Sept. 15 on a mission to provide critical, precision measurements of Earth’s ice sheets, glaciers and sea ice, which will help scientists better understand how changes at the poles will affect people around the world."

While an ice-free Arctic would be a major landmark, another landmark would be open water at the North Pole. Since the thickest ice is not at the pole this is likely to occur significantly earlier, with ice hanging on along the CAA. When do you think this might be? The University of Bremen ice concentration map is already showing rather low concentration near the pole.

This poll will run for 30 days. You may change your vote.

Arctic background / UK Orders New Icebreaker.

"UK science is to get one of the biggest, most capable polar research vessels in the world.

The £200m investment in an icebreaker is to be announced by Chancellor George Osborne in a speech on Friday.

The ship is likely to be 130m long, and sport a helipad, cranes, onboard labs, and have the ability to deploy subs and other ocean-survey and sampling gear."

A canyon running for at least 460 miles (750 kilometers) has been discovered under Greenland's ice. This could influence the melting of the ice. "...the newly discovered canyon could boost the breakup of one of the coastline's briskly retreating glaciers."

"Liberal Democrats are committed to achieving zero net greenhouse gas emissions from the UK
economy by 2050. Our aim is that emissions in the UK should broadly be balanced by greenhouse
gases sequestered in the UK. "

Note that they say zero emissions, rather than zero fossil fuel consumption. I think the UK will have great difficulty producing all its energy without fossil fuel!
