You Are About to See a Whole Lot About Climate Change On-line and On-Air and it is Long Overdue

American Geophysical Union - 5 hours 58 min ago

Many on-air and online news outlets are going to do a lot of climate change coverage this week. This came out of a meeting I attended a few months back at Columbia University and it was sponsored in part by the Columbia Journalism Review. The press, especially TV news, has done a horrible job of covering climate change. Mainly by ignoring it. When they have covered it, the stories were …

Friday fold: crinkled schist from Italy

American Geophysical Union - Fri, 09/13/2019 - 8:55am

AGU’s Chief Digital Officer Jay Brodsky offers up a fresh European fold for you today — and this one is on rather a smaller scale than Jay’s last Friday fold contribution… Click through for a bigger version. These are lovely crinkly folds in highly foliated rocks. I love boxy little crenulations like these. Jay tells me that this is from Graines, Italy, in one of the valleys of the Val …

Glacier Crevasses As A learning Tool

American Geophysical Union - Thu, 09/12/2019 - 4:35pm

Guest Post by Clara Deck Instagram: @scienceisntsoscary   Crevasses on mountain glaciers are large cracks in the ice which often propagate from the surface downward. The initial break will happen when stress exceeds the inherent ice material strength. This article will focus on surface crevasses, though this basic physical understanding also applies to basal crevasses or large-scale rifts in ice sheet and shelf settings.   In mountain glacier systems, crevassing …

Lightning flashes illuminate storm behavior

American Geophysical Union - Thu, 09/12/2019 - 11:38am

Anybody who has ever tried to photograph lightning knows that it takes patience and special camera equipment. Now, a new study is using those brief but brilliant flashes to illuminate cloud structures and shed light on storm cell behavior, giving weather forecasters new tools for predicting lightning hazards.

Lightning ‘superbolts’ form over oceans from November to February

American Geophysical Union - Tue, 09/10/2019 - 3:00pm

The lightning season in the Southeastern U.S. is almost finished for this year, but the peak season for the most powerful strokes of lightning won't begin until November, according to a newly published global survey of these rare events.

How to Manage Your Job Search as a Full-Time Student

American Geophysical Union - Tue, 09/10/2019 - 1:29pm

Senior year of college is stressful enough without the additional pressure of finding a job or impressive internship to start immediately after graduation. Between challenging classes, on-campus jobs, senior thesis research, and trying to savor fun moments with friends, you will probably find yourself pressed for time in every area of your life. As someone who struggled with this balance, I am here to offer some advice on how to …

Sol 2523: Picking Up Where We Left Off

American Geophysical Union - Tue, 09/10/2019 - 9:00am

Today is our first planning sol following solar conjunction. For the past few weeks, Mars and Earth have been on opposite sides of the Sun, preventing routine communications with Curiosity. Our rover spent most of the time sleeping, with some routine environmental monitoring with REMS and RAD and occasional Hazcam images like the one shown.

Shedding light on the invisible: addressing potential groundwater contamination by plastic microfibers

American Geophysical Union - Tue, 09/10/2019 - 7:00am

Until recently, the topic of plastic pollution was relatively unknown to the general public, although the problem was already under everyone’s very eyes. Indeed, plastic pollution has become one of the most debated issues over the last few years, in some cases even overshadowing the concerns about climate change, and with particular concern about the effects of microplastic (i.e. plastic particles smaller than 5 mm in length) in the natural environment.

NWS Director and Chief Science Officer at NOAA Back NWS Hurricane Tweet; Who Wrote NOAA Friday Statement??

American Geophysical Union - Tue, 09/10/2019 - 1:27am

In a (not really) surprising turn of events, Monday, the Director of the National Weather Service Louis Uccinelli and NOAA’s chief science officer publicly backed a tweet issued by the NWS office in Birmingham on Sept. 1st. That tweet (which was scientifically accurate) told residents that Hurricane Dorian would not be a threat to Alabama. It was posted after their phones melted with rumors that Alabama would be hit much …

AGU supports scientific integrity and the critical work of government scientists

American Geophysical Union - Mon, 09/09/2019 - 11:00am

AGU believes in science free of interference and political influence. We support our members and all scientists at federal agencies in the U.S. and around the world who make decisions and announce findings based on evidence and incontrovertible facts. These scientists, including those at NOAA and the National Weather Service, frequently provide research that protects our lives, communities, economy, and security. Interference with their work can impact lives and property …
