A couple of geology and climatology stories today.
Earth science rocks!
Greenland’s newly discovered ice crater, here. Who knew?
********
Unlucky dinosaurs, here. My own theory is that the dinosaurs were wiped out not by post-Chicxulub-impact soot, but by the well-documented health hazards of cigarette smoke. But that’s just me – and Gary Larson, I guess.
********
California’s recent fires and air quality, here. I can tell you that the air around Sacramento has been so bad of late that you can’t even see to the end of Midstream Lane – pictured here in happier times of clearer air.
********
Last but not least – bear with me now, folks – cosmogenic nuclide dating of glaciation, here.
Especially cool is the video from the American Museum of Natural History’s Science Bulletins, here, which follows geologists on a rock-harvest expedition much like the one I went on a few years back with a geologist friend from Colorado College. Our trip was to the Snowy Mountains of southern Wyoming. The one in the video was in New Zealand. But the underlying scientific principles and procedures are the same. What will they think of next?
Interesting to note, sample analysis post-harvest can take literally years due to the big backlog on high-tech equipment needed to determine nuclide levels. One would almost say, the pace of publishing research findings in this field is, well, positively glacial.
