For the last nine years the United States has dodged the hurricane bullet: No major tropical cyclones have made U.S. landfall. Such a remarkable “hurricane drought” has never been seen before – since records began in 1851. It beats the previous record of eight years from 1861-1868, say researchers who have looked into the probabilities of the unusual streak, what it means for the chances of hurricanes this year and whether or not insurance premiums reflect the risks. Their conclusion: the hurricane drought is mostly a matter of dumb luck.

New research matching different types of underwater volcanic eruptions with their unique sound signatures could help scientists better detect and understand emissions occurring on the seafloor.

Torrential rains inside hurricanes might be acting as a control knob on these giant storms, reducing their intensity by as much as 30 percent, according to a new study.

On Dec. 19, 2006, the sun ejected a small, slow-moving puff of solar material. Four days later, this sluggish Coronal Mass Ejection was nevertheless powerful enough to rip away dramatic amounts of oxygen out of Venus’ atmosphere and send it out into space, where it was lost forever. Learning just why a small CME had such a strong impact may have profound consequences for understanding what makes a planet hospitable for life.

Scientists have come up with an explanation of why the Earth rings like a bell.

A new study shows a ubiquitous type of phytoplankton — tiny organisms that are the base of the marine food web – appears to be suffering from the effects of ocean acidification caused by climate change.

On this expedition, we’re studying sediments that have been eroded from the Himalayas, the highest mountain range in the world. The Ganges and Brahmaputra rivers carry this sediment to the delta in Bangladesh, but what happens next? How does this material get all the way out to the middle of the Bay of Bengal where we’re drilling, almost 2,000 kilometers (1,243 miles) away?

Scientists are using massive amounts of information about the climate, weather and land to develop new tools farmers can use to grow more food without harming the environment.

Hurricanes require moisture, the rotation of the Earth, and warm ocean temperatures to grow from mere atmospheric disturbances into tropical storms. But where do these storm cells originate, and exactly what makes an atmospheric disturbance amp up full throttle?
A new study accepted for publication in Geophysical Research Letters finds most hurricanes over the Atlantic Ocean that eventually make landfall in North America actually start as intense thunderstorms in western Africa.

Why are we studying the mountains by drilling into the seafloor?
