Tracking media attention to climate change and global warming, by MeCCO

Sat, 09/28/2019 - 8:53pm

The coverage of global warming and climate change in world media is moving in a promising direction, and bringing students back (or for the first time) to newspapers, radio and TV can expand their sources and information literacy.

Searching for the “biggest” mountain in the Appalachians…and why is “biggest” in quotes?

Sat, 09/28/2019 - 11:58am

A recent visit to Cattail Peak (6,583 ft/2,006 m), a summit in North Carolina’s Black Mountains, left me wondering where the most topographically prominent peaks and biggest possible summit climbs in the Appalachians are located.

Raccoons, wild pigs and other bad ideas

Fri, 09/27/2019 - 11:53am

After reading my column about biologists who once stocked a Southeast Alaska island with wolves, a reader mailed me a book. In it, the author detailed peoples’ attempts to import raccoons, wild pigs and other creatures to Alaska. In addition to well-known events like the recent introduction of wood bison to the Innoko River country, Tom Paul wrote about smaller creatures people have over the years let loose onto beaches and into the woods of Alaska.

So, you wanna host a Twitter takeover (…of our account)?

Fri, 09/27/2019 - 9:51am

Recently, a new word has entered my lexicon: rocur. I've actually had discussions with colleagues responsible for copy editing and marketing about using this word, mainly along the lines of, "that's not a word." This has made me realize I've migrated from one bubble of scientific research in conservation biology to another that's focused on communication, policy, and social media.

Groundwater and a ‘green drought’

Wed, 09/25/2019 - 12:18pm

Here in New South Wales (NSW) in southeastern Australia, a long-running drought continues. The government’s water minister Melinda Pavey noted recently that “This drought is more severe than NSW has ever experienced” and some of the worst in living memory.

AGU’s Journal Space Weather to Become Open Access

Wed, 09/25/2019 - 10:29am

As we celebrate our Centennial year, AGU strives to promote and support the Earth and space sciences, and this includes increasing access to journal content. Starting 17 October, the AGU journal Space Weather: The International Journal of Research and Applications (SWE), devoted to the understanding and forecasting of space weather, will transition to an open access model with all articles accepted after that date accessible free of charge to readers. Space …

Historic earthquakes suggest Trans-Mexican Volcanic Belt’s quiet regions are active

Wed, 09/25/2019 - 9:00am

Seemingly low-hazard seismic regions in Mexico have experienced multiple, strong earthquakes since the 1500s, new research finds, suggesting the regions have many unmapped, active fault lines. The areas are inside the Trans-Mexican Volcanic Belt, home to roughly 40 percent of Mexico’s population, who may be unaware of the land’s seismic history.

Sols 2536-2537: SAM Wet Chemistry Experiment

Tue, 09/24/2019 - 7:00pm

Searching for organic molecules in rocks on Mars is no easy task. Curiosity's Sample Analysis at Mars (SAM) instrument is designed to analyze the chemical composition of gases, which it creates by slowly heating rock samples in an oven.

AGU Releases Report to Address Flooding in Communities

Tue, 09/24/2019 - 8:08am

AGU’s global community of Earth and space scientists has contributed research and expertise to our understanding of—and solutions for—climate change, natural hazards, and their related impacts on people. Climate change, the increasing severity of extreme weather, and resulting floods are health and economic crises that we cannot ignore. To highlight the role that science plays to help address and mitigate issues such as flooding in communities across the United States, …

Organizing a Climate Impact Teach-In

Tue, 09/24/2019 - 6:56am

So what did I learn from organizing and hosting a Climate Impact Teach-In the day before the Global Climate Strike? In short, people want to know what is happening, people want to ask questions and share their own knowledge, and people want to contribute and get involved.

A new analysis of the deadly Anak Krakatau flank collapse

Tue, 09/24/2019 - 1:43am

A paper (Williams et al. 2019) published in the journal Geology provides an analysis of the deadly 2018 Anak Krakatau flank collapse. Interestingly, the landslide was surprisingly small to have generated such a large tsunami.

Response of Orasbreen (O), Glopeken (G) and Holmstrombreen (H) to climate change as indicated by 1995 and 2019 Landsat images.  Red arrow is 1995 terminus, yellow arrow 2019 terminus, pink arrows a deepening supraglacial stream channel and purple dots the snowline. Orsabreen terminates in an expansing prolgacial lake, Trebrevatnet, that is shared with a glacier it has separated from Holmstrombreen. The glacier shares an accumulation zone with Kronebreen, a glacier …

Ice islands on Mars and Pluto could reveal past climate change

Mon, 09/23/2019 - 11:51am

Many of the craters of Mars and Pluto feature relatively small ice islands unattached to their polar ice caps. These ice islands could be records of past climate change on Mars and Pluto, and could also provide clues about the workings of Martian water and ice, according to a new study in AGU’s Journal of Geophysical Research: Planets.
