California’s finally wet enough that the Metropolitan Water District of So Cal could store this year

Inkstain (John Fleck) | 17 January, 2017
This is a big deal: The Metropolitan Water District of Southern California, which gathers water for 19 million people in the region, expects it can now begin storing water for future years. In recent years, it had been using up its water reserves. It...

How darkness and cold killed the dinosaurs

Geospace | 17 January, 2017
Roughly 66 million years ago an asteroid slammed into the Yucatan peninsula. New research shows tiny droplets of sulfuric acid formed high up in the air after the impact, shown here in an illustration, cooling Earth's climate for years to come.Credit: NASA.

Mount Sulzer – a series of dramatic, and extremely large, debris and ice avalanches

The Landslide Blog | 17 January, 2017
Michael Loso of Wrangell-St. Elias National Park and Preserve in Alaska has kindly provided details of an amazing series of debris and ice avalanches that have descended from the flanks of Mount Sulzer in recent years. The Google Earth image below shows the location.  On the left is the site of these major landslides.  The next valley to the west (on the right in this image) has also suffered a glacier surge in the 2015-16 period, but that is not the focus here.

Magnitude 5.7 Earthquake in North Sumatra.

Sciency Thoughts | 16 January, 2017
The United States Geological Survey recorded a Magnitude 5.7 Earthquake at a depth of 10 km, about 18 km to the northeast of the town of Kabanjahe in North Sumatra Province, Indonesia slightly after 7.40 pm Western Indonesian Time (slightly after 12.40 pm GMT) on Monday 16 January 2017. There are no reports of any damage or casualties associated with this quake, but people have reported feeling it across North Sumatra and Peninsula Malaysia.

Shear zones in Scottish gabbros

Mountain Beltway | 16 January, 2017
In 1970, John Ramsay and Rod Graham published a paper about shear zones1. I cited their foundational work of these structures, essentially "ductile faults," in my M.S. thesis, despite the fact that the Ramsay & Graham example shear zones were in otherwise homogenous plutonic rocks, and were a few centimeters wide. In contrast, my study area was the Sierra Crest Shear Zone System, a broad ribbon of deformation several kilometers wide and 100+ kilometers long, and deforming dozens of different lithologic units.

Geochemistry Networking Event held in December 2016... by Ginnie Panizzo

On the 16th December 2016 the Centre for Environmental Geochemistry (CEG) held a Networking event between key female geoscience researchers the British Geological Survey (BGS) and the University of Nottingham (UoN). The main impetus behind the event was to encourage collaboration between Anne McLaren Research Fellows of the UoN from the Schools of Biosciences, Geography, Chemistry and Faculty of Engineering, with other female researchers at the BGS. The invitation was extended to other early and mid-career researchers at the School of Archaeology, due to the strong research linkages with the Stable Isotope Facility at BGS.

The NASA data conspiracy theory and the cold sun

When climate deniers are desperate because the measurements don't fit their claims, some of them take the final straw: they try to deny and discredit the data.

How much water does Arizona need?

Inkstain (John Fleck) | 15 January, 2017
The question of the headline, which was the title for the talks I gave last week in Phoenix was, I admit, a little cheeky. I'm just some schlub from New Mexico with an academic title and a book. That doesn't mean I know the answer to the question. But to the extent I have an answer, it is this - Arizona (and lots of other places) probably don't need as much water as they think.

Neoliberals know the price of everything and the value of nothing

Resource Insights | 15 January, 2017
My father likes to say that some people know the price of everything and the value of nothing. The same could be said of the neoliberals of the world, who--in case you missed my previous piece--are now transcendent in most policy circles across the world.
