Rising temperatures along the bottom of the Atlantic Ocean will force American lobsters farther offshore and into more northern waters, a new study finds. Climate models project that ocean bottom temperatures in the Atlantic along the U.S. East Coast may rise by up to 4.3 degrees Celsius (7.7 degrees Fahrenehit) by the end of the century. The new study’s results show these rising temperatures will likely make conditions in the American lobster’s southernmost range—less hospitable in the future for juveniles, pushing them farther north and into habitats farther offshore.

Scientists have shown for the first time that volcanoes emit distinctive pulses of gas a few hours before erupting, which could lead to real-time forecasting of dangerous volcanic eruptions that are difficult to predict, according to the researchers.

Alaskan residents rely on sustenance species like salmon, caribou, and moose, but their needs can be at odds with companies mining natural resources and conservationists. The state’s future will depend on collaboration between these various stakeholders, and scientists can help bridge the gap between these groups, according to researchers at Southern Oregon University.

Earth’s surface is constantly shifting, expanding and compressing in response to atmospheric and hydrologic forces from aboveground. A new study finds that compression of Earth’s crust is correlated with heavy rainfall from hurricanes and typhoons, known collectively as tropical cyclones. The added weight of all that water likely causes the ground underneath the storm to deform, according to the study’s authors.

Microbes like bacteria aren’t conscious enough to form memories, but a group of scientists in Texas developed a new way for them to do so at the genetic level. Researchers report they’ve successfully engineered microbes to report on their environments and form genetic “memories” of the event. It’s a tool that could help scientists better understand chemical cycling on Earth and how microbes share information like antibiotic resistance with one another, according to the researchers.
Wildfires continue to scar California beyond the normal fire season in what’s been a particularly catastrophic year for natural disasters across the U.S. But a new big-data solution for predicting wildfire spread is also heating up, and it may become a useful tool in the firefighters’ arsenal, according to wildfire researchers attending the 2017 American Geophysical Union Fall Meeting.

Scientists find the lifetime of organic aerosols in the upper atmosphere is on the order of 10 days, far shorter than scientists previously assumed.

Speeding through the atmosphere high above Jupiter’s equator is an east–west jet stream that reverses course on a schedule almost as predictable as a Tokyo train’s. Now, a NASA-led team has identified which type of wave forces this jet to change direction.

Researchers have developed new, high-resolution climate models that may help policymakers mitigate the effects of climate change at a local level.
A global view of some well-known deformation features on Venus’s surface may indicate it’s capable of crustal motion, and that motion might even be happening today, scientists report.
