Centennial Collection:

1. Grassroots Group Commended for Work on Flooding by Virginia House

Stop the Flooding NOW was founded by Virginia Beach residents who wanted to take action to address the chronic flooding in their community.

Climate Change:

1. Reframing Sensitivity Analysis in Earth System Models

According to a new study, the performance metric–based methods currently used to evaluate dynamical model sensitivity are based upon faulty reasoning and need to be reenvisioned.

2. Carbon Could Soon Reach Levels Not Seen in 56 Million Years

New research finds the pace of today's warming far outstrips any climate event that has happened since the extinction of the dinosaurs.

3. Simplifying How (and When and Where) Snow Turns into Flow

A Montana researcher has developed a map for predicting how climate change may alter the water supply.

4. Bridging the Weather-to-Climate Prediction Gap

A task force of researchers set out to bridge the gap between the 2-week weather forecast and long-term climate predictions; their findings could help in forecasting the likelihood of extreme events.

5. Rising Temperatures Reduce Colorado River Flow

Hotter conditions have played a much greater role in reducing flow during the ongoing Millennium Drought than in a mid-20th century drought.

6. Brief, Repetitive Floods in Coastal Cities Cause Economic Losses

A case study in Annapolis is one of the first assessments of the effects of high-tide flooding on local revenue.

7. Can We Predict River Flows from Just a Few Observations?

Improving Discharge Data for Water Resources Management—Hydraulic Modelling as a Tool for Rapid Rating Curve Estimation; Stockholm, Sweden, 8 November 2018

8. Downhill All The Way: Monitoring Landslides Using Geophysics

Developments in geophysical methods used to monitor surface and subsurface changes prior to landslides can lead to improved prediction and early warning.

9. When Floods Cross Borders, Satellite Data Can Help

With so many eyes in the sky, residents living downstream from dams now have many ways to see—and prepare for—potential dangers.

Space & Planets:

1. Asteroid Mission Attempts Touchdown, Sample Grab

Hayabusa2 will fire a metal bullet into the asteroid surface to eject material that will then be collected. The mission will return the samples to Earth in late 2020.

https://eos.org/articles/asteroid-mission-attempts-touchdown-sample-grab

2. New Tiny Moon of Neptune Discovered

The moon's size and orbit point to it being the remnant of a collision with Neptune’s moon Proteus.

3. How Long Can Celestial Bodies Retain Ice?

A new model suggests that many objects in the outer asteroid belt may still harbor deposits that formed around the time of their accretion.

Atmospheric Sciences:

1. Windy Weather in the Thermosphere

The weather in the thermosphere includes winds that buffet spacecraft as they orbit the Earth, but how well can these winds be modeled?

2. Global Impacts of ENSO Reach into the Stratosphere

El Ni?o events have significant global impacts on weather and climate, but these reach up into the stratosphere, beyond the troposphere where most of Earth's weather takes place.

https://eos.org/editors-vox/global-impacts-of-ensos-reach-into-the-stratosphere

Biogeosciences:

1. Baltic Bacterial Blooms Over the Millennia

Eutrophication not only is a present-day anthropogenic phenomenon in the southern Baltic but also occurred over the past few millennia, with cyanobacterial blooms during times of climate warming.

https://eos.org/editor-highlights/baltic-bacterial-blooms-over-the-millennia

Ocean Sciences:

1. Route for Upwelled Kuroshio Waters into East China Sea Shelf

A simple algorithm obtains short-term variations in upwelling, which show that the subsurface Kuroshio waters can upwell directly into the East China Sea shelf under the advection of the Kuroshio.
