 The summer of 2019 found the North Cascade Glacier Climate Project in the field for the 36th consecutive summer monitoring the response of North Cascade glaciers to climate change.  This long term monitoring program was initiated partly in response to a challenge in 1983 from Stephen Schneider to begin monitoring glacier systems before and as climate change became a dominant variable in their behavior. The field team was comprised …

There is an old saying among forecasters that “There is almost always a hurricane on the Atlantic weather map on Labor Day.” Well, Dorian exploded into a hurricane this morning, and it now looks ever more likely there will be a major hurricane near the Florida Coast early Monday (Labor Day). A big hat tip to Katherine Hayhoe for this link about how climate change is impacting hurricanes.

An increase in hotter, drier years in the coming decades due to climate change may worsen water scarcity issues in the Upper Nile Basin. These impacts are likely to cause an increase in agricultural failure in Ethiopia and may potentially lead to civil strife, according to the authors of a new study published in Earth’s Future, a journal of the American Geophysical Union.

A special kind of streaked aurora has been found to track disturbances in near-Earth space from the ground. Known as structured diffuse aurora, it was recently discovered, with the help of NASA spacecraft and instruments, that these faint lights in the night sky can map the edges of the Van Allen radiation belts — hazardous concentric bands of charged particles encircling Earth.

The Solar wind-Magnetosphere-Ionosphere Link Explorer (SMILE) mission is still four years away from launch, but scientists are already using existing ESA satellites, such as the XMM-Newton X-ray observatory and the Cluster mission studying Earth's magnetosphere, to pave the way for this pioneering venture.

Ship emissions caused more than 1,200 ozone-related and 2,500 particulate-related premature deaths in the Pearl River Delta region in 2015, according to new research in the AGU journal GeoHealth. The new study also predicts that implementing new coastal emission controls could reduce mortality due to fine particulates by 30 percent and ozone by 10 percent by 2030.

I don’t think we can over-emphasize the importance of learning student names and the correct pronunciation of their names in our courses. Our introductory-level geoscience classrooms are especially important for recruiting new majors and producing Earth science-literate citizens. If we don’t have a class identity as a supportive and inclusive community for learning and working together, what impact can and will that have for our departments, the discipline, and society as a whole?

Glaciers at Point A and B have melted completely away. The commemoration of a single disappearing glacier in Iceland, Okjokull has brought attention to what is quite a common event this decade, glacier disappearance. Here we report on a number of glaciers in the southern part of the Cumberland Peninsula, Baffin Island  that have either disappeared or separated into several parts  from 2002-2019. Way (2015) noted that on the next peninsula …

Where scientific findings have not conveniently fit into the ideological preferences of political leaders around the world, science and scientists are increasingly under attack. In a symposium on human rights threats to scientists at the 2018 AGU Fall Meeting in Washington, DC, an Iranian environmental scientist shared a chilling story about learning of his imminent arrest if he were to return home from an international trip. Other participants shared stories …
