To mark National Earthquake Day, the Nepal Times has a series of articles entitled Future Shock that examines the failure to learn from the 2015 earthquake

There are about 33 million cattle in Mexico, where a few scientists are experimenting to concoct a cow diet that will reduce methane emissions.
On the western coast of Islay, Saligo Bay showcases turbidites of the Neoproterozoic Colonsay Group. The Smaull Graywacke shows Caledonian (late Ordovician) folding and cleavage superimposed on world-class graded bedding. There’s also a nice dolerite dike to examine.
Changing atmospheric conditions may contribute to stronger ocean wave activity on the Antarctic Peninsula
A new study provides important details on the extent of sea ice, which can protect ice shelves from the impacts of ocean storms, in the Antarctic Peninsula.
I could not make it this year, but the Glen Gerberg Weather Summit (that my friend Dave Jones at StormCenter Communications hosts each January) is one of the best science seminars I’ve ever attended. One of the speakers on Wednesday was Dr. Jim White, who I spent two weeks with (as his guest) on top of the Greenland Ice cap at NEEM. Jim is a GREAT science communicator, with an …

Landsat Image of glaciers examined in the Himalaya Range: Chapter 10 that straddles a portion of Sikkim, Nepal and Tibet, China. Notice the number that end in expanding proglacial lakes. This January a book I authored has been published by Wiley. The goal of this volume is to tell the story, glacier by glacier, of response to climate change from 1984-2015. Of the 165 glaciers examined in 10 different alpine …

After the drive and the post-drive imaging needed to plan Sol 1578 activities, Navcam will acquire a panorama and search for dust devils and clouds.
The challenge lies in how satellites estimate where underwater volcanic mountains might be located. This is achieved by detecting slight changes in the distance between the satellite and the surface of the ocean, which is ever so slightly bulged up due to water piling directly above the seamount, sometimes predicting the location about 1 km from where it actually lies.
Since I showed off the 3D kimberlite intrusion breccias yesterday, I feel as if I owe you some other photos from that lovely exhibit at the IGC. I apologize for the poor quality of these photos – the gorgeous samples were behind glass and brightly lit, which made photography difficult. But the rocks are sooooooooo pretty, I think you’ll enjoy viewing them just the same. Let’s start with a gargantuan …
But the real answer at least for me lies in the fact that as I have bounced through six decades of life and entered my seventh, a time when so many would argue that they have “seen it all,” I increasingly realize how little I have actually seen, experienced and learned.
The 1906 Haverstraw landslide This week marked the 111th anniversary of the disastrous Haverstraw landslide in Rockland County, New York, which killed 19 people. The disaster was caused by the folly of humans, chasing wealth to be made from the excavation of glacial blue clay, ideal for brick making. At the height of the industry there were an estimated 3,000 labourers making 350 million bricks per year in Haverstraw. Over …

Curiosity planning started 2 hours later than usual today because the Sol 1575 data needed for planning weren’t expected until almost 10 AM PST. Unfortunately, the news was not good: An arm fault prevented the MAHLI full suite from completing, leaving the camera close to the surface with its dust cover open.
The first week of the #MappinTheFloor transit/cruise brings the team closer to the Johnston Atoll and time for many of the team to learn new skills, as well as connecting with students across the world. Check out this video and get an inside look into the activities onboard R/V Falkor.
For many, emojis have become a part of everyday life. They act as signatures – smiley faces, frowns, you name it. Personally, I never really strayed far from those two, but there are hundreds, if not thousands out there. And, even though there are so many and such diversity, the sciences are not well represented. We’re out to change that.
Only 2012 was hotter than 2016 in the U.S., by .5 degrees F. It will not be official for a few more days but 2016 will be the hottest year globally as well for the third consecutive year. NASA will have their data out first and then NOAA. and the Arctic Sea ice looks to be in a free fall…. via GIPHY

After a 25-meter drive on Sol 1574, Curiosity again has bedrock exposed in her arm workspace. To balance desires to sample the composition of the rocks along the traverse and to make good progress toward the south, contact science and another drive are both planned for Sol 1575.
Remember a couple of months ago when Google Earth Timelapse got updated? I didn’t spend a lot of time looking at it back then, but I’ve taken it for a spin since then and – being a volcanologist – decided to look at volcanoes. And it turned out to be a lot of fun.
A Landsat image from 1989 and a Sentinel 2 image from2016 illustrate the retreat of Coronation Glacier. Red arrows indicate the 1989 terminus and yellow arrows the 2016 terminus location. Purple numbers 1-5 indicate locations of tributary retreat or thinning. Purple numbers 6-9 are icecaps that did not retain snowcover in 2016. Coronation Glacier is the largest outlet glacier of the Penny Ice Cap on Baffin Island. The glacier has …
