Beechey Island update

 A previous blogpost here almost 7 years ago showed how to use a niche product to create detailed elevation model of Beechey Island. Posted on Google Earth here (download & open it in Google Earth, see 'GE' below), it allowed to add a Parks Canada photo of the Franklin Expedition landing site: it was the first one uncovered by University of Alberta's Owen Beatty in 1984, the year before I spent a summer in the Arctic 'nearby' the other side of King William Isl. on the west shore mid-Boothia Peninsula... We were in fact told to report any unusual findings!

See a fascinating 2021 report on the Franklin Expedition at Heritage Portal here.

I stated in the previous post that:  

GE is not great for sharing, it only offers facilities to email place-mark [...] so I posted them and the whole data set under CC BY-SA 3.0 on Google Drive. Also created a YouTube video of same:

Well to remedy that, I recently found a QGIS project where I created the contours and posted it on free Qgis Cloud (zoom out to locate yourself in the Canadian Arctic Islands):

London Thames Barrier update

Update: here is the transcript of Hansen's latest "in plain English" (here if PDF download fails)

Two weeks ago I recreated Sea Level Rise (SLR) and Risk of Flooding (RoF) maps for the lower Thames River near the Thames Barrier (blog) for a WhatsApp Group considering the future of its ageing infrastructure w.r.t. recent climate extremes. This week came a global and urgent update affecting Sea Level Rise, by James Hansen who sounded the alarm ~ 35 yrs ago (go to 1981 & 1988 in Medium): a paper incl. supplementary materials "Global Warming Has Accelerated" (Columbia) c/w companion webinar (Columbia).
