Don’t Like The Science- Make up Your Own Alternative Science

4 hours 36 min ago
Make up your own science and then send it to 200,000 teachers. This will turn out to be a real waste of money for Heartland, and the reason is that most Earth science teachers will toss this in the waste bin. That’s a good place for it, but before you do, you could use it to explain what real peer-reviewed science is compared to an opinion based on worldview. It’s also …

Vallunaraju Glacier Retreat, Peru 1992-2016

7 hours 4 min ago
Vallunaraju Glacier comparison in Landsat images from 1992, 1995 and 2016.  Red dots represent the 1992 margin and yellow dots the 2016 margin The Cordillera Blanca, Peru has 27 peaks over 6,000m, over 600 glaciers and is the highest tropical mountain range in the world. Glaciers are a key water resource from May-September in the region (Carey, 2010).  Mark Carey describes the importance of glacier runoff to the Andean society in …

Robopocalypse, by Daniel H. Wilson

12 hours 36 min ago
Okay, let’s get this out of the way up front: In no no way is Robopocalypse of anything like the caliber of Our Final Invention or Superintelligence. Though written by an author who holds a PhD in robotics from Carnegie Mellon, this is an adventure novel. It explores some interesting aspects of a AI vs. humanity conflict, but it’s basically constructed in a way that’s very much mano a mano, …

New study shows how impacts generated Martian tsunamis

13 hours 10 min ago
A study published last year interpreted images of the red planet and suggested the deposits were made by impact-generated tsunamis more than 3 billion years ago. In a new study, Costard and his colleagues independently build on that work by including the geological characteristics of the deposits and modeling how impact-generated tsunamis could have created them. They conclude the deposits may have come from asteroids slamming into a northern ocean billions of years ago, generating waves 300 meters (nearly 1,000 feet) high.

How stories captivate an audience

Tue, 03/28/2017 - 11:42am
How do stories captivate an audience? Here, I’ll identify the relevant story parts of one documentary film and describe how the story contributes to the film's success. Then I'll discuss one film where storytelling is virtually absent.

Sol 1650: Let the scooping begin!

Tue, 03/28/2017 - 10:27am
Over the weekend, Curiosity bumped to our scooping location at “Ogunquit Beach.” We have a wheel scuff in the left side of our workspace and a sinuous ripple crest in the right side of the workspace, which according to today’s Geology Science Theme Lead Michelle Minitti is “everything a dune lover could want!”

The Fake Climate Debate and The Real One

Tue, 03/28/2017 - 3:31am
I just finished reading a paper by Michael Mann, Stefan Rahmstorf et.al in Nature Reports today that is getting some deserved press attention. It’s rather complicated (OK, for non-atmospheric science geeks, it’s a brick) but in plain language, it indicates that the warming of the climate is doing what many of my fellow forecasters have been suspecting for quite some time: changing the upper-level wind flow and therefore changing our …

Believe the Positive…It’s Probably True

Mon, 03/27/2017 - 4:58pm
Confidence is a powerful thing, and as it turns out, a lack of confidence is a debilitating thing.  Years ago, Saturday Night Live’s Stewart Smalley encouraged us all to say, “I’m Good Enough, I’m Smart Enough, and Doggone It, People Like Me!”  It’s a self-affirmation that we could all use from time to time. Many new graduates, and even more students, fear that they aren’t all that they need to …

Look Up and Say Hello to Altocumulus Asperitus and Cirrus Homogenitus

Sat, 03/25/2017 - 7:54pm
It was Luke Howard, a Fellow of the Royal Society, who first gave us the cloud names like cirrus, stratus, and cumulus (that we still use today), and that was way back in 1802! This is important because to understand something, you first have to observe and classify it, and this is true of all science, not just meteorology. So, it’s big news when we add some new cloud names, and if …

Creating a Scientific Poster in PowerPoint: A Video Tutorial

Fri, 03/24/2017 - 6:17pm
As part of our continuing series designed to help participants in the Virtual Poster Showcase, we’ve created a video tutorial showing how to create a scientific poster. The video specifically shows the steps needed to create a scientific poster using PowerPoint. Though the video is intended for AGU Virtual Poster Showcase participants, the same steps can be applied to creating posters for any conference. This video will walk you through the steps …

5 Things to Know About the New House Earth & Space Science Caucus

Fri, 03/24/2017 - 12:45pm
What is a caucus and why is it important? A caucus is a way for members of Congress to show support or interest in an issue outside of the committees on which they serve. Some caucus are well-known such as the Congressional Black Caucus or the Oceans Caucus. The Earth & Space Science (ESS) Caucus seeks to increase understanding amongst Congress of the sciences’ impact on policy and to facilitate …
