Newest Element of AGU’s Digital Strategy Focuses on Engagement, Experimentation and Open Data

Tue, 07/25/2017 - 2:23pm
AGU has long been a proponent and leader in open data and open science, not only in our own publications and meetings, but also within the broader research community. I’m pleased to announce that we have taken that commitment to the next level today by launching an Application Program Interface (API) that will open the door for scientists, developers, and others to create innovative applications that advance science and our …

Researchers uncover 200-year-old sunspot drawings in Maine

Tue, 07/25/2017 - 9:46am
In April of 1815, the volcanic eruption of Mount Tambora in Indonesia caused a global decrease in temperatures for the following few years, and 1816 came to be known as the “year without a summer.” New England states were particularly hard hit by these temperature changes, which significantly affected agriculture production and quality of life. Alongside his journal entries, Reverend Jonathan Fisher of Blue Hill, Maine sketched the sunspots during the summer of 1816, thinking they might be responsible for the cold summer temperatures.

Rare Tornado in Queen Anne’s County Maryland

Tue, 07/25/2017 - 3:21am
We rarely see tornadoes on the Eastern Shore, but a strong EF 2 (winds near 125 mph) hit Kent Island just SE of the Bay Bridge at 1:30 AM Monday morning. Tornadoes are rare in Maryland and the last tornado in Queen Anne’s County was in 2012. Some of my thoughts about it: 1. Usually, the Chesapeake Bay weakens storms as they cross over it, but when the Bay is …

Two good new landslide videos have been posted on Youtube: a topple from Pandoh and a wedge failure from elsewhere in Himachal Pradesh in India

NASA mission surfs through waves in space to understand space weather

Mon, 07/24/2017 - 2:00pm
By Mara Johnson-Groh The space surrounding our planet is full of restless charged particles and roiling electric and magnetic fields, which create waves around Earth. One type of wave, plasmaspheric hiss, is particularly important for removing charged particles from the Van Allen radiation belts, a seething coil of particles encircling Earth, which can interfere with satellites and telecommunications. A new study in the Journal of Geophysical Research: Space Physics, a …

Could “cocktail geoengineering” save the climate?

Mon, 07/24/2017 - 11:00am
Geoengineering is a catch-all term that refers to various theoretical ideas for altering Earth’s energy balance to combat climate change. New research from an international team of atmospheric scientists published by Geophysical Research Lettersinvestigates for the first time the possibility of using a “cocktail” of geoengineering tools to reduce changes in both temperature and precipitation caused by atmospheric greenhouse gases. Carbon dioxide emissions from the burning of coal, oil, and gas …

Humanitarian groundwater projects; notes on motivations from the academic world

Mon, 07/24/2017 - 5:00am
Globally, the need for regional hydrologic humanitarian efforts is obvious. Even today, 1,000 children die due to diarrhoeal diseases on a daily basis.

The Cognitive Bias Survival Guide

Fri, 07/21/2017 - 5:39pm
As a reporter in Tampa was doing a story on an Alligator in the road yesterday, someone drove past and screamed “Fake News!”  I suspect the gator was real, and the story was factual, but this is happening rather frequently. You might ask how people can be so deceived that they will accept news only from those who tell them what they want to hear. Unfortunately, this is the America we …

Mountain glaciers recharge vital aquifers

Fri, 07/21/2017 - 10:49am
Small mountain glaciers play a big role in recharging vital aquifers and in keeping rivers flowing during the winter, according to a new study. It suggests that the accelerated melting of mountain glaciers in recent decades may explain why arctic and subarctic rivers have increased their water flow during the winter even without a correlative increase in rain or snowfall.

Friday fold: Sardinia

Fri, 07/21/2017 - 7:52am
My friend Ander Sundell at the College of Western Idaho is the source of today’s Friday fold. It’s from somewhere in Sardinia, and I think you’ll find it visually striking: Ander says: The rocks here are Silurian phyllites generated from mudstones that were deposited on the floor of the rheic ocean basin. The color and grain size variation do an excellent job highlighting compositional layering. They were deformed during the …

Ellsworth Glacier Retreat & Lake Expansion, Alaska

Thu, 07/20/2017 - 5:16pm
Ellsworth Glacier in 1989 and 2016 Landsat images.  Upper yellow arrow marks the west terminus in 2016 and the lower yellow the 2016 east margin.  Purple dots mark the snowline and purple arrows tributaries from the east that are thinning and disconnecting.  Orange arrow marks icebergs in the lake.  Ellsworth Glacier is a valley glacier draining south from Sargent Icefield on the Kenai Peninsula in Alaska. Along with the Excelsior Glacier it …

Dog partner enhances hike across Alaska

District Days: August is Coming!

Wed, 07/19/2017 - 3:39pm
It’s that time of year again. Winter August is coming! Throughout next month (also known as “August Recess”), members of Congress will be home in their state and district offices to host events at home and meet with constituents to talk about their priorities. This is a prime time for you to meet with your legislators and tell them about the value of science to your local community. We know …

CV’s, resumes, & scicomm?

Wed, 07/19/2017 - 11:42am
By Shane M Hanlon I had a discussion the other day with a friend who is in the process of updating her resume as she’s likely to be promoted at her current job. She was lamenting about how time intensive it was and how she couldn’t quite remember everything that she’s accomplished since her last update while also worrying about what to fit into it due to space constraints. I …

A Different Way of Visualizing The Global Temperature Rise

Wed, 07/19/2017 - 3:22am
Gavin Schmidt at NASA GISS posted the graphic below on Twitter Tuesday night and it quickly spread like wildfire. We are used to seeing the graphs with hockey stick endings of the global temperature but showing it in a sequence of normal distributions (bell curves) by month, and ending it with the data of the last two years noted, gives one a new and rather stark perspective. You can see an animation …
