Optimism continues on the other boat blog.mailasail.com/suilven/214"Today we have woken to flat calm and low cloud and a playful walrus that came for a close inspection of us. Ice to the west of us continues to block progress for the time being so we shall wait and see what develops over the next few days. It is surprisingly warm, with the temperature reaching 12 C yesterday afternoon, so hopefully the thaw will happen quite fast now."

They will have a nice couple of days, then the weather turns against them. weather.gc.ca/city/pages/nu-10_metric_e.htmlWith the concentration to their west, via cryosphere today, I don't see this voyage making it this year. But, I have ben wrong before. Look how low I thought the ice area would be, and it has actually started building the last few days.

Arctic sea ice area continues to turn to the right.

Steven Goddard blogs: No Change In Arctic Sea Ice Over The Past 40 Years According to the the 1990 IPCC report, the Arctic sea ice anomaly in 1974 was almost -1.0 million km². Essentially identical to 2014. There has been no change in Arctic ice coverage over the past 40 years. If you have ever wondered why Arctic sea ice graphs now begin in 1979, the 1990 IPCC report makes it clear. 1979 was the maximum ice extent of of the satellite era, and the data from before 1979 wrecks their global warming story.

I thought satellite records were only available from 1979 onwards Where do these records back to 1975 come from?

I thought satellite records were only available from 1979 onwards Where do these records back to 1975 come from? Hi Neil, The full 1990 IPCC report is available here: www.ipcc.ch/ipccreports/far/wg_I/ipcc_far_wg_I_full_report.pdfOn page 224 the above sea ice extent graph can be found with the accompanying text: "satellite observations have been used to map sea-ice extent routinely since the early 1970s." The 1990 IPCC report predates the removal of the Medieval Warm Period. The chart below can be found on page 202, and look there it is that inconvenient MWP. An observation relating to the Northern & Southern hemisphere sea ice graphs (page 224) - the ice in the North diminishes as the ice in the South expands (and vise versa) - just as we're witnessing at present? It appears to me that the current global sea ice extent is very similar to that of the early 70's (low North, high South) & hence nothing to worry about...

myself I think there quiet a bit to worry about .. high ice at the south .. rebounding ice at the north and it's not even begun to get cold yet ...but it still all depends on how quiet the sun will get and for how long

If they decide not to proceed they have to sail south. I presume there will be a fine balance on how long they can wait so far north

]It looks like they may have missed the thaw window thing. Certainly does, MASIE isn't currently supporting the notion of a small craft crossing of the NW Passage: Link: nsidc.org/data/masie/MASIE data from the Sunshine hours blog: Link: sunshinehours.wordpress.com/

It is only first of August. That ice will look very different by mid august. That said though those keeled boats have no ability whatsoever to pass thru even small amounts of lightly compressed ice so its no place to be taking a 14 year old boy if its not plain sailing.
