In a new paper, Hughes et al. (2014) have shown that there is a the remains of a large rock avalanche at Arroumd in the Atlas Mountains of Morocco. Dating suggests that this might have been triggered by an earrthquake on a nearby fault about 4500 years ago.
I have mentioned the lectures you can buy from the Teaching Company before here, and one of those lecture sets is a six lecture series called The Inexplicable Universe, by Neil deGrasse Tyson. It’s worth the money IMHO, but before you buy it, Netflix has made available this entire series for its customers. That’s a pretty good deal. Now, this series does not have all the flash bang the COSMOS …

A group of researchers from Texas A & M University have a paper in the Proceedings of the National Academy of Sciences (PNAS) this week that is getting a lot of attention. Cloud droplets and rain drops need something to form on, and without dust and other aerosols in the atmosphere we would see a lot less of both. Sometimes though, the addition of particulates can cause tiny cloud droplets …
Last week I got to spend a couple of days in lovely Boulder, CO for a meeting (fortunately right before Sunday’s snow). The meeting (which was for the Thriving Earth Exchange’s Advisory Board – keep an eye out for updates!) kept us inside a lot, but the NCAR facility that hosted us has some fantastic views of Colorado’s Front Range and the famous Flatirons. The boulders in the foreground and …

The Dart River landslide in New Zealand is an unusual case of a complex landslide that has generated valley-blocking debris flows. A new GNS Science report provides the details.

Today I’m continuing with my series of posts about my October 2013 visit to the small town of Sutherland in South Africa’s Northern Cape province. Sutherland is home to a South African Astronomical Observatory (SAAO) research station that contains many telescopes, including the Southern African Large Telescope (SALT). You can read Part I of this series here and Part II of this series here. Today I’m going to share some pictures from our visit to the SAAO Visitor …

Science fiction can be a really cool gateway for sharing science fact. Earth science is imaginative, and can draw on pop culture, like the HBO show Game of Thrones. My graduate school friend and Generation Anthropocene co-producer, Miles Traer, recently brought science fact and science fiction together over this show in a hilariously awesome and super fun project.
I’ve written before here about how pervasive the myth is that science is divided about the reality of and the threat of man-made interference with our climate system. It truly is the number one science myth out there. Just by writing this post, I’ll get the usual comments with links to the usual rabid political sites (with unflattering pictures of Al Gore) telling me that thousands of scientists disagree, and …

With some trepidation, we knocked on the first climate scientist’s door. Although we’re seasoned science writers at major research institutions, the request we were about to make was far different from our usual ones for interviews or images from field expeditions. We had decided to create a 2014 Climate Models wall calendar, using climate scientists as models, in the belief that humor can be used to deliver serious messages in a less serious, but still meaningful way.

What causes this? Very good website about it here: It was a bit chilly with an onshore sea-breeze, but sparkling early spring sunshine in spite of it being 10° C. I got a decent pic of the Ocean City pier that was damaged by a February nor’easter. Also notice the Jet contrails over the Eastern Mediterranean today. This image from the NASA Terra satellite about 600km up. Dust blowing off …
On the last day of my visit to Scotland, my advisor and her husband (both former UB volcanology folks) took me on a hike to Holyrood Park to visit Arthur’s Seat, Edinburgh’s volcano.

Research published this month in Geophysical Research Letters, a journal of the American Geophysical Union, calculates the environmental impact of phasing down hydrofluorocarbons, or HFCs, under the Montreal Protocol. The landmark 1987 agreement phased out the use of ozone-depleting refrigerants, like chlorofluorocarbons (CFCs), leading to increased used of replacements that include HFCs.
The March Sea Ice Record is downward at 2.6% /decade. The melt season is now extending by 5 days per decade. Most of the ice is very young ice so the melt will likely be rapid, depending on weather conditions.

The northern coast of Chile has been struck by a Great earthquake this evening, shaking the South America continent for hundreds of miles and thrusting a tsunami onshore and across the Pacific Ocean. Notably, this earthquake occurred in a well known seismic gap, the sole reach of South America’s Pacific coast subduction zone that did not rupture in the 20th (or 21st) century. In that sense, this was one of …
There has been some speculation as to whether the Oso (Steelhead) landslide in Washington could, and should, have been foreseen. The answer is yes!
NOTE: I wrote this just after 8 PM on the first not the second. That’s APRIL FIRST..hint! (The date tag uses GMT so it showed as April 2nd) The State Dept. accused Bubba Brothers Coal Company in Mudville, WV today of selling technology to China to hide its cities and military installations from spy satellites. The view (from NASA Satellites) above shows how effective it has been, and shows evidence …

Most of the public is turned off by scientists’ overly accessible and personalized descriptions of their work, new research shows.

There are so many ways that repositories for canisters of nuclear waste can leak that at least one country, Sweden, is engineering the canisters themselves to last a million years. In general, however, the integrity of nuclear waste repositories depends on a host of geologic factors, Jean Bahr, a professor of geoscience at the University of Wisconsin-Madison said at a briefing earlier this month on Capitol Hill.
Check out the immense climbing ripples preserved in surge deposits at Hunt’s Hole (a maar volcanic crater in southern New Mexico) and imagine the strong currents couples with an extraordinary amount of entrained pyroclastic material.
