How to build AI Agents

This follows on my AI "lessons-learned,  lessons-shared" mainly on my Ongoing Crash Course here, that links all items on my various socials.

Maryam Maradi (LinkedIn) shared on-going how-to's I pay-forward here to the rest of the world. I posted the texts on the links below her excellent posters also in-text (click to enlarge). My (liked) comment on her second post was:

This is so excellent! I'm a geologist & GIS-er of 40-odd yrs., w interest in geophysics in general & seismic in particular. I have never seen such a comprehensive review and sign of hope for disaster response... Thanks!

... Samurais in early 1600s Spain!

This follows on from a map story here. A follow-on is here.

Update: fascinating twist in failed outreach by Elizabeth I to China at the bottom.

I thought that So. Cal. Spanish missions were early (mid-18th c.)... well here's an earlier story of intrepid early diplomats & missionaries - not seasoned sailors as Longest tall ships routes here - after long-distance missionaries of the Apostolic Levant here. Perplexity opens here as:

More map art, Part II

This follows on a map story hereThe next one is here

The original "More map art" is  here: a world map in Natural Earth projection with Mean Annual Climate Temperatures and Natural Earth countries.

Equal Earth vs. Spilhaus projection, masking onshore areas

The original post starts as "a few years ago I used Charlie Frye's online lesson Explore future climate projections to learn how to use NetCDF and map temperature regimes - it's shown below in Patterson & Savaric's Equal Earth Projection..."

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

Longest haul flights, longest rivers, longest tall ships routes & bonus map

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

A series of maps are posted here; they're in desktop and map or poster but not web format as explained herehere; sit back folks, relax & enjoy the map story time...

I repost a cool map on long haul flights: I grew up taking earlier ones over 50 yrs. ago; one of the carriers I used, Qantas just announced here jets that can fly Sydney to New York or London direct! Next is a new map of the longest rivers from a website priding itself of its visualisations: I used previous techniques and cannot decide which works best; perhaps you the reader can help?

Update: added a long section on longest sailing routes by 18-19 c. tall ships (think Cutty Sark here).

Update 2: this post here follows on this series of offline maps
