Peatlands release more methane when disturbed by roads

Roads built through acidic wetlands may make greenhouse gas emissions from the wetlands spike by damming natural water flow, according to a new study in AGU’s Journal of Geophysical Research: Biogeosciences.

Can Arctic ‘ice management’ combat climate change?

Both sea ice retreat and global warming could be slowed by millions of wind-powered pumps, drifting in the sea ice, to promote ice formation during the Arctic winter. Researchers have now, for the first time, tested the concept using a complex climate model.

New study models impact of calving on retreat of Thwaites Glacier

A new study in the AGU journal Geophysical Research Letters modeled how much faster Thwaites, one of West Antarctica’s largest and fastest-retreating glaciers, would retreat in the absence of its ice shelf — the part of the glacier that floats on top of the sea, supporting the thicker ice behind…“Worst-case scenario, it is going to be gone in less than a century. But it may also take much longer.”

New study finds the mix that makes Titan’s lakes spew nitrogen bubbles

In a new study published in AGU’s journal Geophysical Research Letters, researchers simulated Titan’s lakes in a pressurized chamber. They found the right combination of methane, ethane and nitrogen crucial for bubbles to form. It is possible these bubble outbreaks are strong enough to shape river deltas in bodies of liquid on the moon.

Weather in Malaysia provides early forecasts for UK, study finds

“It was once said that the flap of a butterfly’s wings in Brazil could set off a tornado in Texas, and our study provides new evidence of the remarkable interconnectedness of the world’s weather” – Robert Lee, University of Reading

Geoscientists develop technology to improve forecasting of earthquakes, tsunamis

University of South Florida geoscientists have successfully developed and tested a new high-tech shallow water buoy that can detect the small movements and changes in the Earth’s seafloor that are often a precursor to deadly natural hazards, like earthquakes, volcanoes and tsunamis.

Size of thunderstorm dome clouds may predict tornado intensity

The size of a bulge at the top of a thunderstorm’s anvil-shaped cloud may allow researchers to forecast the strength of tornadoes that spawn from such storms, according to a new study in AGU’s journal Geophysical Research Letters.

For the first time in the history of space exploration, scientists have measured the seasonal changes in the gases that fill the air directly above the surface of Gale Crater on Mars. As a result, they noticed something baffling: oxygen, the gas many Earth creatures use to breathe, behaves in a way that so far scientists cannot explain through any known chemical processes.

Advancing spring warmth could disrupt species migration, development

In a new study in the AGU journal Geophysical Research Letters, scientists found that in many areas of the U.S. springtime temperature thresholds important for plant and animal life cycles occur between six to 20 days earlier in the season than they did 70 years ago.

Satellite tracking shows how ships affect clouds and climate

By matching the movement of ships to the changes in clouds caused by their emissions, researchers have shown how strongly the two are connected.
