By Ned Rozell As another major rainstorm hit California in February, downtown San Francisco surpassed its normal rain total for an entire year. Reservoirs in the high country were spilling over. So ended a five-year drought in the state that some people attributed to human-caused climate change. Those pictures of dried-up California lakes bothered Syun-Ichi Akasofu, who recently gave a talk “The Forthcoming Ice Age” at the University of Alaska …

A stalagmite collected from a remote cave in the Middle East has revealed that recent droughts there were more severe than previously thought, and therefore possibly an important contributing factor for the turmoil in Syria. A research team traveled to Iraq to collect the stalagmite and used it to present the first ever detailed climate reconstruction of the Fertile Crescent extending back 2,400 years.

Surfers aren’t the only people trying to catch big waves. Using decades of global climate data generated at a spatial resolution of about 25 square kilometers (10 square miles), researchers were able to capture the formation of tropical cyclones and the extreme waves that they generate. Those same models, when run at resolutions of about 100 kilometers (60 miles), missed the tropical cyclones and the big waves up to 30 meters (100 feet) high.

A team of scientists led by postdoctoral researcher Takatoshi Sakazaki, from the University of Hawaiʻi at Mānoa’s International Pacific Research Center (IPRC), has analyzed satellite-based observations and computer model simulations of tropical rainfall variation throughout the day in an effort to determine the root cause of the temporal patterns. Their results, accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union, show that daily tropical rainfall distribution is significantly shaped by heating of the upper atmosphere.

The breakdown of methane hydrates due to warming climate is unlikely to lead to massive amounts of methane being released to the atmosphere, according to a recent interpretive review of scientific literature.
A new study finds evidence that the last time Earth was as warm as it is today, cold freshwater from a melting Greenland Ice Sheet circulated in the Atlantic Ocean as far south as Bermuda, elevating sea levels and altering the ocean’s climate and ecosystems.

A team of oceanographers has developed a new model for ocean wave energy, using an 1883 account of how a ship’s crew dumped oil into stormy seas and calmed the waves enough to save the crew of a sinking ship.

Urban plants offer city dwellers many benefits, such as improved health and decreased crime and pollution. And now we have even more reason to green our cities. A new study from the Water Sustainability and Climate project at the University of Wisconsin-Madison indicates that adding more greenery to the urban landscape could help urban vegetation cope better with the summer heat and a warming climate. In other words, the more plants in a city, the merrier they all are.
New climate index based on atmospheric pressure produces more accurate predictions of storm wave conditions
A method based on the north-south atmospheric pressure gradient along the Atlantic coast of Europe could lead to enhanced forecasting of extreme wave conditions and increased preparedness within coastal communities, a new study suggests.

Dust released by an active coal mine in Svalbard, Norway reduced the spectral reflectance of nearby snow and ice by up to 84 percent, according to new research.
