Thunderstorms directly above two of the world’s busiest shipping lanes are significantly more powerful than storms in areas of the ocean where ships don’t travel, according to new research.
A new study mapping lightning around the globe finds lightning strokes occur nearly twice as often directly above heavily-trafficked shipping lanes in the Indian Ocean and the South China Sea than they do in areas of the ocean adjacent to shipping lanes that have similar climates. 

The National Science Foundation is funding the largest marine seismic-monitoring effort yet along the Alaska Peninsula, a region with frequent and diverse earthquake and volcanic activity. Involving aircraft and ships, the new Alaska Amphibious Community Seismic Experiment will be led by Cornell University in Ithaca, New York, with partners at the University of Washington and seven other research institutions.
“This effort will really change the information we have at our disposal for understanding the seismic properties of subduction zones,” said Emily Roland, a UW assistant professor of oceanography and one of nine principal investigators on the project. 

The Northern Rocky Mountain ecosystem includes huge swaths of federal lands, two national parks and some of the most spectacular wild spaces in the country. University of Washington researchers are helping managers of those lands prepare for a shifting climate.
“Climate Change and Rocky Mountain Ecosystems,” a book published in August, was edited by Jessica Halofsky, a UW research ecologist in the School of Environmental and Forest Sciences, and David Peterson, a senior research biologist with the U.S. 

While winter sea ice in the Arctic is declining so dramatically that ships can now navigate those waters without any icebreaker escort, the scene in the Southern Hemisphere is much different. Sea ice around Antarctica has actually increased slightly during winter — until last year.
About a year ago, a dramatic drop in Antarctic sea ice during spring in the Southern Hemisphere brought its maximum area to its lowest level in 40 years of record keeping. 

Warming of the planet by 2 degrees Celsius is often seen as a “tipping point” that people should try to avoid by limiting greenhouse gas emissions.
But the Earth is very likely to exceed that change, according to new University of Washington research. A study from lead-author and Professor of Statistics and Sociology Adrian Raftery and Associate Professor of Atmospheric Sciences Dargan Frierson uses statistical tools to show only a 5 percent chance that Earth will warm 2 degrees or less by the end of this century. 

New research finds that large earthquakes can trigger underwater landslides thousands of miles away, weeks or months after the quake occurs.
Researchers analyzing data from ocean-bottom seismometers off the Washington-Oregon coast tied a series of underwater landslides on the Cascadia Subduction Zone to a 2012 magnitude-8.6 earthquake in the Indian Ocean — more than 8,000 miles away. These underwater landslides occurred intermittently for nearly four months after the April earthquake. 

Inventor and entrepreneur Jerry Paros and University of Washington scientists are monitoring undersea faults for movements and signs of the next catastrophic earthquake. A recent Nature article looks at Paros, who has donated $2 million to the UW, and the collaborative project he’s working on with researchers including the School of Oceanography’s Emily Roland and William Wilcock. Over the course of his career, Paros developed an ultra-precise quartz sensor for oil, gas and other industry applications. 

John E. Vidale, a University of Washington professor of Earth and space sciences, is among 84 new members and 21 foreign associates elected this week as members of the National Academy of Sciences. Academy members are recognized for their distinguished and continuing achievements in original research, according to a news release from the academy.
Vidale studies Earth’s interior, including earthquakes and volcanoes. 

The mountain pine beetle has destroyed more than 40 million acres of forest in the western United States — an area roughly the size of Washington state.
The beetles introduce a fungus that prevents water and critical nutrients from traveling within a tree. They also lay eggs under the conifers’ bark, and their feeding larvae help kill trees — sometimes just weeks after the initial attack. 

The U.S. Geological Survey and university, public and private partners held an event April 10 at the University of Washington to introduce the ShakeAlert earthquake early warning program as a unified, West Coast-wide system. The event also introduced the first pilot uses of the earthquake early warning in Washington and Oregon.
The first Pacific Northwest pilot users of the system are Bothell, Wash.-based RH2 Engineering, which will use the alerts to secure municipal water and sewer systems so these structures remain usable after a major quake.
