Climate & ecological emergency (CEE) from global to local

David Brower, founder of Friends of the Earth, 1970s environmental slogan “think globally, act locally” needs to be recast ½ c. later to “think globally, observe locally” in order to better act locally: that is why I push Citizen Science  thru this blog & provide tools, say, to build your own maps here; see the banner map on the desktop not mobile blog here. 

Mapping Arctic Boreal Peatlands

This follows on East Anglia environment in a global context. A recent article, Peatlands across the Arctic are expanding as the climate warms, research shows  via @physorg_com, made me look to map data for that. I posted a fair bit on East Anglia peatlands in this blog. I also recently used polar Arctic basemaps N of 50°lat., like Arctic Waterfront, a measure of geopolitical stakes, amongst this blog's Arctic coverage. Next post is Mapping Arctic Boreal Peatlands, cont..

Henry VIII Dissolution of Monasteries in England

This continues history posts from Roman Roads vast network and local effect, to medieval travels by Richard I and by Samurais.

Inspired by National Archives' story map: Discover the Dissolution of Monasteries by Henry VIII from 1536 to 1540, here is its intro:

 Henry VIII's break from Rome and the creation of the Church of England set in motion a revolutionary chain of events that resulted in the closure of almost 900 religious houses, displacing 12,000 people from their religious orders. While some were allowed to remain or convert, many were given pensions to surrender their churches and many still were simply evicted with no compensation. The dissolution changed the kingdom's schooling, medical care, land ownership and powerful figures - but why did it happen, and how did it affect your local area?

A Belgian holiday

 This picks up from A Roman Holiday about aspects of Roman Roads. A friend pointed out this YouTube video, How A Roman Road Changed Belgium Forever, here is their synopsis:

Why does Belgium speak two languages? The answer is a 2,000-year-old Roman road.

In this video, I explain how the Via Belgica, a highway built by the Roman empire around 50 BC, created a language border that still divides Belgium today. The road ran from Tongeren to Bavay, separating Romanized Gaul in the south from Germanic tribes in the north. That linguistic divide has persisted through the Middle Ages, Spanish rule, Austrian rule, French occupation, and Belgian independence.

Today, Dutch speakers live north of the line, French speakers live south of it, and the border is still influenced by that ancient Roman road. Even Belgium's election results are decided by this 2,000-year-old line.

Having mapped Roman Roads, I recreated a focussed map on the region, adding the Belgian Wallonie region in green. As roads were unidentified in the AWNC database, I selected them per video. I found a source (no metadata in arcgis.com) that put Via Belgica right along it, confirming my choice.

East Anglia environment in a global context

This follows on blogposts about East Anglia in general here. It continues on Arctic peatlands news here.

The last post on infrastructure affected by sea level rise is here. Contrast below Environment England's Risk of flooding from river and from sea at left for waters coming naturalls from onshore & offsore, and my Seal level rise model by simply intersecting various sea level elevations and Ordnance Survey topogaphy (intro here and workshop here). Think of it below as fresh water largely going NE to the North Sea at left, and at right as sea water encroaching largely SW onto the land:

A Roman Holiday

This follows on a map story here. Next history map is here. 

Update : check out below how a new map, itiner-e, updated the Roman Roads view.

Update 2: speaking of malaria in second map, appended maps on trade routes that triggered the Black Plague in the 14th c. Mediterranean.

Update 3: And here is a news story on Alexander the Great's port rediscovered in So. Iraq, well inland today of the then Persian Gulf.

Not William Wilder's 1953 Gregory Peck & Audrey Hepburn flick (Wikipedia)! When drawing up a map of Apostolic Palestine for local Catholics, I ran across Ancient World Mapping Center (AWMC) at UNC-Chapel Hill. While their web app (ArcGIS Online) is a cool one-stop-shop for their rich data set - for ex. I cannot do point clustering (Comet Assistant) with my standard Argis Pro desktop license -  I loaded, picked apart an re-sorted some of their data for some interesting insights. 

2050 Scenario? Atlantic Meridional Overturning Circulation (AMOC)

This follows on a map story here.  The next one is here.

After revisiting a number of topics for just over a year here, let's address an item of some urgency: stalling the Gulf Stream may end Western Europe's historic privilege; to be a warm enclave between two 'normal' bands at its latitudes. It's not an Ice Age but think how much colder New York and Montreal are than London or Paris. 

It may be hard to wrap our minds around cooling at a time where climate warming hits the headlines - and rightfully so -  and before climate deniers jump on this, please consult the scientific consensus behind all this under two Microsoft Copilot headings at the bottom: AMOC update, a political declaration of Nordic countries affected and estimated timeline of its collapse.

Update 1: AMOC collapse effect presented at the National Emergency Briefing last week in London here HT YouTube @JustHaveaThink

Update 2: data support my graphics under Precisions just before Bonus at the bottom.

More maps, in 3D now

Update 3: follow on next post "Even more maps, with a twist" here.

Update 2: found a textbook example of  "carving upstream" in this gorgeous video of the Uinta Mountains of Wyoming.

Update 1: more offshore canyons crowning Antarctica found with new digital terrain data and give us a beautiful map @ bottom.

This follows on the previous map story here. The next one is here for maps & here for geomorphology. 

Another map request

Update 2: added a new map post here in my ongoing series of revisiting here

Update 1: added at bottom a new map adding to an existing Antarctic project

Pyrénées

When visiting the nearby village of Pontacq (Flickr & village site), the glorious sunshine showed the Pic do Midi de Bigorre (Wikipedia) so clearly we could see the observatory atop! It's the left peak in the central massif below.

East Anglia Peatlands revisited

Update1: see clipped oroginal and working vector datasets posted as detailed at bottom.

Update 2: added DIY map-mapping workshops & notes to help citzen science

Update 3: here at the end is the relevance of this sort of effort in a broader context

Update 4: worrying revisit of peatlands degradation with increased drought & extreme weather here: increased heat degraded carbon absorption, and that is mirrored in tropical forests turning into carbon emitters seen here

Update 5: see follow-on here: East Anglia environment in a global context

This follows on previous Peatlands blog posting here, last of the Community Engagement Series.

As news abounds about Arctic Permafrost & Peatlands degrading faster than thought (Copilot), this may be a good time to bring back some Natural England and Environment Agency data under Open Government License (OGL, National Archives). The upshot is that returning peatlands to their original state is the biggest climate change mitigator in the UK detailed here & here: briefly, peatlands either degraded thru neglect or converted to farm land, not only shrinks & stops being floodwater catchment, but it converts carbon sinks through sphagnum moss into carbon emitters thru windborne dried peat. In other words, re-watering peatlands dwarf efforts from other mitigation of climate change (see sources at bottom).

A brief web history of mine

Update: re: my last paragraph, I restored my personal portfolio as a re-post of my original www.zolnai.ca here and my professional portfolio as a free-tier for developers here. Remaining socials are on desktop not mobile blog here.

As I wind down my blog posts and I quit socials, perhaps this may be a good time to reflect on my Web journey that started almost 40 years ago (a recap of my IT journey is here)...

But wait... Tim Berners-Lee didn't invent it til just over 35 years ago (Wikipedia)! That's because I had a site dubbed HTTP in 1986, see inset below:  "world wide web" hadn't been coined yet, but I knew as a student at late 70's University of Calgary of Ted Nelson's failed Project Xanadu (Wikipedia), to try and link all forms of knowledge via hypertext; it failed partly due to Nelson's eccentricity,  partly because there was no global network to carry it. 

Senegal delta sea level rise map

Five friends at Arts & Metiers engineering school in Paris took a ten month leave to sail around the North Atlantic: Lez'Arts Marins (here) sail south from Britanny past the Azores & Madeira to Senegal for a moth humanitarian aid project, west across to Martinique and northeast N of Scotland to Scandinavia and back.

Cumbria classic revisited, Appleby-in-Westmoreland

Almost four years ago, a story map here showed the Skelworth Fold area of the Lake District for a friend, using advanced mapping and Environment Agency digital elevation.

"AI for the rest of us", Part VII

Update: the last of a series, follow my recap blog post here incl. Medium Channel posts on AI.

Note: the last post on my personal Medium channel shows how I used Copilot AI to good effect for fact-checking. 

Last we showed here how to create "quick & dirty" graphs while chatting on ur mobile. Now we'll see how we can create summaries, not from "text to hand", but from that cribbed off the internet. 

Having left socials, I'm down to corresponding at Extinction Rebellion "Media Tell the Truth" WhatsApp group. Jon Fuller there is also at "Climate Genocide Act Now" here. I was a scientist for Extinction Rebellion, and blogged here about the pandemic against the lies of the British government, as well as about floods and rising sea levels in East Anglia. I didn't know GCAN, however, as I'm no longer active.

Global sea level rise revisited

Update: so follow-on here with definions and relationsips among these topics

I posted here 3 yrs. ago among a series of DIY map notes to encourage Citizen Science, how to use NOAA global digital elevation data to model sea level rise data on straight geometry. See also here for an explanation referring to East Anglia. Here is what it looks like from the DIY document:

A return to my roots

Updates: mapping climate data from historic ships & global harmonization follow respectively here & here.

 "You can get Andrew outa maps, but you can't get maps outa Andrew" quipped a GIS map friend when I left Kuwait a dozen years ago... Well after quitting socials, Esri(UK) graciously helped me recover my desktop app. While I lost my story maps and web maps content, I maintained a free dev account - story maps and maps&data - this was chiefly to preserve my Living Atlas content inspired by John Nelson. 

Community engagement and social prescribing

Community Engagement 1,... 20, 21, 22, 23, 24 & 25

This follows an update on this blog here, where I announced my move away from Cambridge. This is also a good place to end the Community Engagement series. I will however continue on topics as they arise like re: AI here, or Sea Level Rise here & updated Thames Barrier starting here. Follow also the Blog Archive to the right-hand side of the desktop version here, as well as the right-hand side of the Banner Menu atop.

We recently rebranded Cottenham.info to Cambridgeshire.ai: the domain name is acquired but page not done yet finished; we have a prospectus as an evergreen document, meaning ever evolving.

Our community involvement over 5 years in March is one object of this blog starting  here (follow the links) and listed here. We engaged with various community interest  parties at the impact of climate change then the pandemic on social isolation in East Anglia.

Community Interest Company blog recap

Community Engagement 1,... 20, 21, 22, 23 & 24

As I move away from Cambridge to SW FR in my family home, I will also exit socials and rethink my online engagement, where I lost all my pensions! I have also moved my domain to a new provider: it preserves this blog, Personal & Professional Portfolios and My Year+ in Kuwait in my web (not mobile) blog banner menu here; it loses the superseded web page and my email now on Yahoo. I do, however, stay engaged with my Community Interest Company Cambridgeshire.ai at right. See following post here.

AI Prompt Engineering Trial 2

Community Engagement 1,... 20, 21, 22 & 23

Update 2: next blog installment is here.

Update1: Medium prof channel reflects this here.

My post here, starting my experiment to convert my CIC (non profit) from Cottenham.info to Cottenham.ai, showed how can we use AI (Wikipedia) for good. My CIC started to address rural isolation in East Anglia in light of climate change and the pandemic (here and here). After a COVID hiatus forced this reassessment, the advent of AI piqued our interest beyond the hype in the press - see my companion Medium series on this topic, following four posts from The future is digital… only it’s not what you think! here - this lead into a curious interaction and my partner finding a new direction.
