9:00 AM | Images of Guatemala (9) – Conflict and Disasters
Until 1996, Guatemala was in the midst of a brutal Civil War. This sculpture in the Presidential Palace of Guatemala City is a reminder of that troubled past and symbolic of a hopeful peaceful future. In the same way that conflict/disasters can hamper and set-back development efforts, conflict can also set-back disaster risk reduction and management. Even once finished, past conflicts can erode trust between different groups. High levels of trust are a crucial factor in both […]

7:07 AM | Sideshow Apatosaurus sans background
I made these for my own use in talks, and then thought, why be selfish? Like everything else on this blog, these images are now released to the world under the CC-BY license. Have fun with them. You can read my review of the Sideshow Apatosaurus here; the TL;DR is that it’s awesome. And if […]

11:57 PM | Geo 1095: January 22, Day 752: Unrooted Roots
This is a big-leaf maple down the creek a ways (maybe a mile or so?) below North Falls. Hardwoods like this don't add girth, generally speaking, as quickly as similar-aged conifers, so I'd guess this tree is in the neighborhood of a century old or so. When it was a mere sapling, it sent roots out in many directions to find water and the nutrients it needs. One of those became well established near what I'd presume was the then current soil level. In the past 100 years or so, soil has been […]

The Doomsday Clock is just three minutes from midnight due in part to climate change.

10:50 PM | Gravity Wave Ripples on The Satellite
The wave clouds on this image over Virginia are caused by winds flowing over the mountains. As the winds lift they form a cloud, and as they fall back down the air warms and dries out (and the cloud dissipates). These ripples happen because the air is fairly stable and does not want to go too high or low from its original height. So, after it goes over the mountains …

4:50 PM | DNews: Stashing CO2 Deep Underground: Does It Work?
All that CO2 and where to put it...? How about underground? But would a catastrophe ensue? Would the planet explode? For answers, Julian looks at work being done by Archer Daniels Midland in the, er, groundbreaking area of underground CO2 storage.

3:23 PM | MS Student Aims for Career in ESG Measurement
Current Master of Science in Sustainability Management (MSSM) student Divya Bendre had just completed postgraduate work in Policy Studies and was working in management consulting in Singapore when she stumbled upon an article by Steve Cohen entitled “Educating Sustainability Professionals” that changed the trajectory of her career path. Divya joined the program because she felt the flexible curriculum would help her to combine her interest in sustainability with her academic and […]

3:23 PM | Museum of Northern Arizona to Offer Adult Learning Classes on the Colorado Plateau
The Museum of Northern Arizona will offer three different courses this winter/spring related to the natural history of the Colorado Plateau. This is an excellent opportunity for those who live within the Flagstaff area to expand their knowledge of this beautiful landscape. The price of each course is a fantastic deal as well. The courses will be taught by experienced and passionate instructors who have many years of formal training and educational experience on the Plateau. General information […]

3:20 PM | “This is not a wet place.”
The University of Arizona’s Mike Crimmins: But the real answer might be for Arizonans and other people of the southwest to adapt to living under drought conditions. “We expect it to be a lot wetter than it is and it should be,” Crimmins said. “Just look around, the landscape tells the story. This is not ...Continue reading ‘“This is not a wet place.”’ »

2:59 PM | The lip of the caldera
One last post from my September trip to Greece. Here’s a look north along the inside wall of the central caldera of Santorini, taken from the deck of the Santos Winery. It’s not hard to imagine the volcanic edifice that filled the space to the left (west) prior to The Big One.

2:44 PM | From the Contracting Earth to early Supercontinents
“What are they?Creations of mind?- The mind can make Substance,and people planets of its own With beings brighter than have been, and give A breath to forms which can outlive all flesh.”“The Dream“, Lord Byron (1788-1824)Already when the first maps of America were published (1507 and after), geographers and naturalists alike noted the similar shape of the west-coast of Africa and the east-coast of South America.In 1620 the English philosopher Francis […]

The Earth once had a frozen shell of ice encasing oceans, land, from pole to pole. The mystery: what process could suffice To kiss Snow White, rouse cryogenic soul. One theory says volcanic CO2 Would slowly warm the Earth until the thaw As ice breaks up, the air and water brew: Carbonic acid forms: paleo-spa. The isotopes of boron measure bases. Post-glacial carbonates record the change As acid

11:30 AM | Field Photos: Basalt Landscapes Around Fort Ghangad Near Pune
Its that time of the year when I go wandering in the basalt countryside around Pune. Its always a fine day off exploring the myriad valleys and mountain ranges. Last Sunday I had gone with some friends to fort Ghangad about 80 km west of Pune, situated near the backwaters of the Mulshi  Dam.The interactive map below shows the location of the fort and a synoptic view of the landscape and geology too (more on that later).Fort Ghangad- A small mesa landform. You can see the ramparts at the […]

10:00 AM | The wrinkled retainer returns with a Peer-reviewed Peer
There is much ado at Tannochbrae Manor, because the Laird has once again disproved global warming. One equation is all it takes! And an article in a new Chinese science journal with some friends, and lo! Take away that inappropriate and misapplied equation, remove the unjustifiable tripling and the climate “crisis” vanishes. You couldn’t make […]

7:52 AM | Wie passen 10 km Rohr auf ein Schiff?
Die JOIDES resolution kann extrem tief bohren: selbst in 9000 Meter Wassertiefe kann sie noch 1000 Meter in den Meeresboden hinein bohren. Das bedeutet, dass bis zu zehn Kilometer Bohrrohr vom Schiff nach unten gelassen werden können! Das Bild rechts verdeutlicht die extremen Größenverhältnisse. read more

6:43 AM | The oceans are warming so fast, they keep breaking scientists' charts
Ocean heat content data to a depth of 2,000 meters, from NOAA. Wow, was this a bad year for those who deny the reality and the significance of human-induced climate change. Of course, there were the recent flurry of reports that 2014 surface temperatures had hit their hottest values ever recorded. The 2014 record was first called on this blog in December and the final results were reported as well, here. All of this happened in a year that the denialists told us would not be […]

6:24 AM | Risk-Based Land Use Canada
New Westminster, BC and the Fraser RiverI'm presenting a short talk on lessons learned or not on landslides at a Risk-Based Land Use Workshop. The workshop is associated with a Risk-based Land-use Guide: Safe Use of Land, Based on Hazard Risk Assessment (Geologic Survey of Canada Open File 7772). Being non Canadian, I am coming at this as a bit of an outsider which means I am learning a lot.As for lessons I am pushing: landslide run out and LiDAR.Debris flow run out, Whatcom County, […]

1:24 AM | Curiosity update, sols 814-863: Pahrump Hills Walkabout, part 2
Curiosity has spent the last two months completing a second circuit of the Pahrump Hills field site, gathering APXS and MAHLI data. The work has been hampered by the loss of the ChemCam focusing laser, but the team is developing a workaround. Over the holidays, the rover downlinked many Gigabits of image data. The rover is now preparing for a drilling campaign.

11:25 PM | non-geology spam
Environmental geology is a pretty small corner of the scientific world, I know. And the vast majority of applied scientists out working in industry today are likely in some corner of the (human) biology world.I get more biological spam than I do environmental or geology spam. And I've been to enough conferences that I'm on just about every environmental mailing list out there. Today, it was an international (very prestigious, they swear) journal of medical science that wanted submissions from […]

11:05 PM | Geo 1095: January 21, Day 751: A Landscape in a Creek Bed
Here we have another exercise like this one from the tail end of last year. "The point is, if all you could see was the sediment in the creek- no horizon, no vegetation, no location- you could still infer much of the environmental setting, just from the nature and arrangement of the sediment itself." We do see some vegetation, and the shadows from the bridge, constructed of 4x4s and 2x4s, give a convenient scale. But by and large, all we can see is the stream sediment.What can we say about […]
