Researchers predict areas of mosquito-borne disease risk in Brazil
Tracking human demographic, climate, and environmental data may help scientists predict and prioritize areas with high risk for mosquito-borne diseases, according to new research.
New early warning system could protect vulnerable islands from flooding
A recently developed early warning system can forecast floods on coral-lined coasts worldwide and could help save residents of low-lying island nations from unprecedented disaster, according to researchers.

Penguins! From space
Today at 2 pm EST, AGU is holding a press conference titled “Penguins! From space” at Fall Meeting 2018. New research will be discussed about how studying satellite images of penguin poop, or guano, in west Antarctica can give scientists an idea of how penguin diets changed over decades or centuries. To help you get a picture of the penguin research, check out this beautiful comic, created by JoAnna Wendel.

Wintertime Arctic Sea Ice Growth Slows Long-term Decline: NASA
New NASA research has found that increases in the rate at which Arctic sea ice grows in the winter may have partially slowed down the decline of the Arctic sea ice cover. As temperatures in the Arctic have warmed at double the pace of the rest of the planet, the expanse of frozen seawater that blankets the Arctic Ocean and neighboring seas has shrunk and thinned over the past three decades. The end-of-summer Arctic sea ice extent has almost halved since the early 1980s. A recent NASA study found that since 1958, the Arctic sea ice cover has lost on average around two-thirds of its thickness and now 70 percent of the sea ice cap is made of seasonal ice, or ice that forms and melts within a single year. But at the same time that sea ice is vanishing quicker than it has ever been observed in the satellite record, it is also thickening at a faster rate during winter.

New automated volcano warning system forecasts imminent eruptions
Scientists have developed an automated early warning system for volcanic eruptions, according to a new study. The new system helped government officials warn the public of impending eruptions in Italy and could potentially do the same around the globe, according to the study’s authors. The new research details the new system that monitors volcanic noises and automatically alerts officials if an eruption is imminent. The study’s authors tested this system over a period of eight years on Mount Etna, a volcano on the island of Sicily. Using the new system, the Italian government activated an emergency plan about one hour prior to an eruption for the first time in late 2015.

Study: Climate change could force outdoor workers to wake up far earlier
A new study published in Earth’s Future, a journal of the American Geophysical Union, indicates that if society tries to avoid the economic impacts of climate change on outdoor labor by shifting working hours, outdoor workers in many regions will need to start working well before dawn at the end of this century to avoid the effect of excessive heat stress.

Pacific Ocean typhoons could be intensifying more than previously projected
Changes to the uppermost layer of Earth’s oceans due to rising temperatures are likely causing an increase in intense Pacific Ocean typhoons, suggesting strong typhoons may occur more frequently than scientists project in the coming decades, according to new research.

Oil extraction likely triggered mid-century earthquakes in Los Angeles
Six independent earthquakes and two aftershocks of magnitude 4.4 to 5.1 shook LA between 1935 and 1944, a rate of about one every two years. A new study re-examined historical information about the earthquakes from archived damage reports to refine the earthquake locations identified by early earth-motion sensors, placing them closer to many active oil fields.
