I. Climate change:

1. U.S. Wildfire Smoke Deaths Could Double By 2100

A new study simulating the effects of wildfire smoke on human health finds continued increases in wildfire activity in the continental United States due to climate change could worsen air quality over the coming decades.


2. Dramatic Stratospheric Warmings Carved a Hole in the Ionosphere

A new study of sudden temperature spikes in Earth’s stratosphere could improve space weather forecasting.


3. Landslides Send Carbon-Rich Soils into Long-Term Storage

Earthquake-triggered landslides move soils down steep slopes and deposit the sediments near rivers, sequestering the carbon contained within them for millions of years.


Ⅱ. Hazards & Disasters:

1. an We Build Useful Models of Future Risk from Natural Hazards?

Natural hazards cause thousands of deaths and inflict tremendous societal damage every year. The database of the United Nations Office for Disaster Risk Reduction shows that the United States alone experienced 212 disasters between 2005 and 2014, worth $443 billion in damage. Worldwide over that same period, 700,000 people were killed, and 1.7 billion people were affected by disasters. As a priority for action, the United Nations Sendai Framework urged a fundamental switch from merely responding to disasters after the fact to a proactive strategy of planning and resilience to reduce vulnerability to disasters before they occur.


2. Lightning: A New Essential Climate Variable

Lightning is a symptom and a cause of climate change. A recently established task team is working to make lightning data available and useful for climate science and service applications.


3. We Can Work It Out: Avoiding Disasters

Strengthening societal resilience by focusing on the interactions between natural hazards, the built environment, and human societies.


4. Endocrine Disruptors Found in Bottlenose Dolphinsiono

Evidence of exposure to phthalates, chemical compounds used in hundreds of consumer products, has been found in bottlenose dolphins in Sarasota Bay, Florida. Some phthalates have been linked to reproductive problems in humans.


Ⅲ. Space & Planets:

1. Webb Telescope May Detect Minerals from Shredded Worlds

The upcoming James Webb Space Telescope should be able to measure the composition of vaporizing exoplanets, giving clues about the makeup of their cores, mantles, and crusts.


2. ramatic Stratospheric Warmings Carved a Hole in the Ionosphere

A new study of sudden temperature spikes in Earth's stratosphere could improve space weather forecasting.


Ⅳ. Education:

1. Helping Geoscience Students Thrive in Graduate School

Ten factors that help liberal arts undergraduate students succeed could also increase the odds for student success in geoscience graduate programs.


2. Budgeting Ozone-Depleting Emissions from Coastal Tidal Marshes

Brackish wetlands and their salt-tolerant vegetation are significant methyl halide emitters. The natural emissions add chlorine and bromine to the stratosphere, which break down ozone.


Ⅴ. Geology & Geophysics:

1. Successful Testing of Technique to Measure Seafloor Strain

A new optical fiber interferometry strain sensor tested off the Oregon coast holds promising prospects for seafloor geodesy.
