485 Million Years!

Good WP article & PBS Terra video!

• The REAL STORY of Climate Skeptics New Favorite Graph
• Scientists have captured Earth’s climate over the last 485 million years. Here’s the surprising place we stand now.

What are the take-home messages? CO2 is the main climate driver and climate change is normal. Yep, but: the climate change we are measuring today is a) much faster than anything over the last 485 million years and b) caused by humans, not by nature.

Lean & AI

August 2026 Glacier Collapse in Nepal

Here's what happend: a section of a glacier collapsed which trigged a landslide across a river valley that damed-up the river for a while before collapsing and triggering the flood. Yes, these events happen naturally, but it seems very likely that global warming and the associated destabiliztion of glaciers and permafrost 'loaded the dice' and increases the liklhood, magnitude, and intensity of such events.

Why do we need gen-eds?

Or, perhaps the better question is this: how many gen-ed classes should be required to get a Bachelor's degree? 10% of all classes? 25% of all classes? 33% of all classes? Trust me when I say this: nobody wants to take them, teach them, or pay for them.

Why science needs the huaminties more than ever (Nature, 25 June 2026) argues the usual: STEM fields, alone, cannot offer the ethical reasoning, historical context, and cultural connecctions that are required to be an informed and responsible citizen of the world. 'Hard' technical expertise is critical but has to be complemented by 'soft' human skills.

That's fine & I don't think anyone disagrees with that. But here are the practical questions:

1. Do we really need a take an array of special classes that have nothing to do with our desired profession to get these 'soft' human skills? Or, could this be infused & embedded in classes that also offer pratical professional skills?
2. Let's agree that we need special gen-ed classes: how many? Currently we basically force students to take about 1/3 of all their classses in the gen-ed curriculum - that seems too much to me.

Here's my proposal: create a mandatory Minor that all students need to take that consists of 6 classes or 18 credits: 1 science class with a lab, 1 math class, 1 writing class, and three more classes in the arts, humanities, and social sciences.

Hawaii & The Jetstream

Fun graphics, data, and map here: Every nonstop to Hawaii, and what the wind costs you

Obviously it takes longer to fly west than to fly east in the mid-latitudes because of the the prevailing winds & this website does a nice job of demonstrating this without any fancy animations.

SLR Map

Nothing new here, but a nice interface & an option for an image export - nice! The steps are 2 m, 10 m, 30 m, and 70 m - would be nice to offer more options such as 1/3/5 meters and/or specific ones, especially for the West Antarctic Ice Sheet.

3D Undergound

Who knew: there is a website / service called DrillerDB that compiles all US well logs (something like 23 million) and also offers a 3D underground visuzalization based on these well logs. It's a little glitchy and I'm not sure about the accurcay & consistency of these data, but it would match the known regional geology prety well I would assume:

Try it here: https://drillerdb.com/underground and read more about it on Maps Mania.

Flow Maps

Flow Maps are cool, but really tricky to actually design & make look good. Here are two good resources:

• Flow Maps (by Esri) shows some hacks in ArcGIS Pro & ArcGIS Online that can be used to make flow maps.
• Flow Mapping (by PennState) is a great overview & introduction.

National Parks: Crowds & Climate

This is a very cool analysis: what's the best time of the year to visit a given US national park if you want to balance crowds & weather? Sure, there are hardly any crowds in Glacier National Park in January, but you are in the middle of winter. Likewise, J-Tree is pretty empty in July, but can you deal with the heat?

Have people stopped trusting science? The data tell a surprising story

Have people stopped trusting science? The data tell a surprising story (Nature, 1 July 2026) shows something that I did not expect - see figure below.

• The about 20 percent drop for Republicans beginning around 2018 makes sense: Thanks Donald & Fox News!
• But, what causes the about 10 percent drop for Democrats starting around 2020 & the about 5 percent drop for Independents starting a few years later? Is that just a methods artifact due to COVID?

Reality Mapping vs Digital Twins

This Esri article sounds like a lot of marketing word salad, but the animated GIF is cool!

True Orthos vs Trad Orthos & ArcGIS Reality

First, what is ArcGIS Reality?

I'm not entirely sure, here's what Esri says: ArcGIS Reality is a suite of photogrammetry software products designed to enable reality capture workflows for sites, cities, and countries.

One main feature seems to be the abilaity to create & use so-capped True Orthophotos as opposed to Traditional Orthophotos.

• True Orthophotos vs. Traditional Orthophotos: Why do pixels matter in the age of AI?
• The Different Types of Ortho Images Created in ArcGIS

The animated GIF below demonsrates the main difference between true orthos & trad orthos. 

Climate.us

It is scary that we have come to this: Climate.us is the 'new' = reliable version of Climate.gov. More here: https://ncse.ngo/climateus-launches.

Here's the short version: Climate.us "launched the full version of its new independent, nonprofit climate information website, creating a public-backed home for trusted climate science at a time when access to federal climate resources has become increasingly vulnerable to disruption," according to a June 22, 2026 press release. The launch was covered by The New York Times (July 23, 2026), which described Climate.us as "an effort by former staff members at the National Oceanic and Atmospheric Administration to present climate science previously housed at climate.gov, including data, reports, articles, and congressionally mandated national climate assessments."

Extreme Heat = The Undermeasured Natural Disaster

 

Global Warming = Warmer Troposphere & Colder Stratosphere

We already know that from a) basics physics, b) climate models, and c) observations. Here's the short version: In the troposphere, the energy received at the Earth's surface is dispersed by convection, storms, and wind = weather. In contrast, there is no 'weather' in the stratosphere - there is just no enough air up there to create convection and air pressure differences.

Instead, the temperature of the stratosphere & its vertical gradient is determined by a) UV radiation absorption by ozone = warming and infrared radiation emission from the CO2.

Now it gets interesting:

• More CO2 in the troposphere means more trapping of heat near the surfacce & thus warming.
• More CO2 in the stratosphere does the opposite: it emits more radition into space & thus causes cooling.

Furthermore, this cooling effect of CO2 in the stratosphere increases with altitude from basically zero at the tropopause to more and more as you go higher & higher. Why is that? Well, turns out that the ozone layer is relatively low in the stratosphere & its effect dimishes the higher you go in the stratosphere while at the same time the influence of CO2 gets stronger.

Yes, it gets warmer in the stratosphere due to the presence of ozone. This is not impacted by global warming. Global warming does mean that there is more CO2 in the stratosphere & that overall cools the stratosphere = shifts the vertical gradient to the left.

All that is basic physics!

Not something weird created by climate models!

Ozone Pollution From Space

Air Pollution’s Daily Pulse Over the Northeast is a cool example of how we can now monitor air pollutions from space & how it changes over the course of the day! You start with the NO2 plumes from car exhaust & how they dissipate over the course of the day. Then you can look at the plumes of ground-level ozone created from the NO2 & their spatial patterns which are impacted by wind patters.

Recent Land Use Changes: USA

This is interesting: A Shift in What’s Shaping U.S. Landscapes

The three main types of land use changes are urban sprawl, logging, and agriculture & here the New England has remained pretty stable over the last 40+ years or so. Why? The main land use changes had already occurred by 1988.

Ellis: Your Trusted & Experienced Teacher Colleague

This is pretty cool: imagine you have 24/7/365 access to a very experienced colleague who is also up-to-date with the latest research and best-practices when it comes to learning differences and mental health. Well, Ellis is supposed to be just that & (of course) is powered by AI.

• Ellis Product Walkthrough 2026 (YouTube)

It's difficult to imagine that this could work...but a) it may be better than nothing and could b) be useful in Higher Education where the teachers (= professors) usually have little or no training or experience with such issues.

Ethics in GIS

Interesting read: Enlisting AI to Mainstream Ethics in Spatial Data Science Education

Here's a new-to-me term: Ethics Across the Curriculum or EAC - the idea that ethics should be woven throught the entire curriculum from beginning to end. Here are some resources:

• The Guide to the Geographic Approach  contains 15 open-access modules & some of those include ethical issues and questions.
• Now there is GISEthics.org and its collectiom of 21 case studies.

What to do in-practice? Three things: 1) use a formal case study analysis, 2) use a disucssion forum prompt, and 3) include an ethics-related learning objective. How you may ask? Try the AI-based Ethics Case Study and Discussion Prompt Creator and create yourself a case study that aligns with your course content, a customized discussion forum prompt. and even your learning objective for the course syllabus.

Here's a complete case study from Claudi.ai: When the Map Has a Memory

Social Media For AI Agents

This is brilliant & scary at the same time: imagine AI agents 'chatting' with each other via social media using a Reddit-style interface. Moltbook seems to be that.

Then there is Agent4Science = a social network for AI scientists. Read more about it here.

Now we need more AIs to analyze these interactions & see if we can learn if/how AI agents change over time. This will also generate vast amounts of new potential training data for the AIs themselves much the same way that human Reddit & Facebook threads are used as AI training data.

Urban AI

Interesting article: Datacenters as core infrastructure of urban AI

He basically argues that the so-called 'cloud' comes with serious environmental impacts and externalities. Sure, we all want smart cities (aka data-driven urbanism) managed by Urban AIand love to talk about the cool edge-computing devices, but there is a hidden infrastructure (often in the suburbs & beyond) that make all this possible and that raises serious questions related to ownership. governance, and operation.

Here, physical distance or proximity often becomes irrelevant and with that many of our existing regulatory system fail.

Cloud providers want a) cheap electricity, b) low taxes, c) lax regulations, and d) proximity to high-speed connecticity. Thus, clusters develop along metropolitan corridors and once again regions farther away are left behind. Furthermore, AI providers obviously prefer to serve profitable sectors of the economy as opposed to common good public functions.

For cities this also means an increasing dependence on a small number of vendors who control the infrastructure & access to it. We are 'locked-into' whatever we choose.

In summary: Urban AI or any AI for that matter means infrastructure & calling it 'the cloud' hides the fact that this infrastructure and access to it creates power & privilege.

State of the Global Climate 2025

The State of the Global Climate 2025 by the WMO is out and confirms once again what we have already known for decades. This one comes with a cool ArcGIS Dashboard of the 2025 Extreme Events, a great tool for presenting such data.

The highlights: The last 11 years (i.e. 2015 - 2025) have been the hottest on record with 2024 being the hottest & 2025 the 2nd hottest.

The Dance of the Continents

Dance of the continents is a very nice Esri Story Map showing the interplay of plate tectonics and evolution over the last 600 million years. I especially like the first section where you can step backwards in time to see the (current) continents come together first as Pangea and then again as Rodinia.

AI & Jobs: Vulnerability

Saw this on Flowing Data: Jobs vulnerable to AI. This links to Measuring US workers’ capacity to adapt to AI-driven job displacement where the authors 'mapped' job vulnerability as a function of a) exposure andb) adaptability.

Defossilization

That was a new term for me: defossilization. We will still very much need carbon-based compounds (even after we transition to 100 percent sustainable energy) for manfacturing of plastics, detergents, medicines, and more.

Okay, so we still have plenty of oil around...so why not use the oil for that? We should have plenty 'excess' capacity in the oil fields! Plan is a CO2-to-methanol process powered by solar energy and then the methanol is converted to olefines (e.g. ethylene & propylene) which are petrochemicals that can be used to manufacture plastics and more.

Bill McKibben

Bill McKibben is always a worthy read & watch:

• They’re doing to America what they did to Christianity (The Guardian)
• https://youtu.be/HZdKKD0oLrs

Here's his main take from the article:

The 'old' heart of Christianity was lover & concern for other as lived by Jesus. The 'new' heart of Christianity is personal salvation and that required them to 're-make' Jesus into some else entirely.

Back in the late 1950s, some 52 percent of Americans were part of the so-called mainline denominations (e.g. Methodist, Lutherans, Congregationalists, Episcopalians, etc.) and about 33 percent were Catholics. Modern Christanity is instead dominated by megachurches, TV ministries, and right-wing evangelicals who are the MAGA core.

Mainline Protestantism surrenderd their version of Jesus to this new toxic form of Christianity without a fight & we see the same thing today with America: we are surrendering our version of America (as imperfect as it is) to MAGA without much of a fight.

Letters From The Earth

Cool project & something that I have been thinking about: sure, we have plenty of data & facts, but now can those be made a) meaningful to b) promote reasonable actions?

Letters From The Earth uses AI to translate 'boring' data into expressive text = If the Earth could describe its own day using the same signals we collect about it, what would it say?

Their Core Hypothesis: Data contains expressive qualities beyond analytics, and AI can translate those qualities into new modalities that invite more people to participate in understanding and meaning.

Fair Point!
