Larger Pacific Climate Event Helps Current La Nina Linger

Posted By dane307 in Fluid Mechanics

Boosted by the influence of a larger climate event in the Pacific, one of the strongest La Niñas in many years is slowly weakening but continues to blanket the Pacific Ocean near the equator, as shown by new sea-level height data collected by the U.S.-French Jason oceanographic satellite. -

New Atlases Use NASA Data to Chart Ocean Winds

Posted By dane307 in Fluid Mechanics

Several new atlases of ocean wind patterns around the globe, based on data from NASA's QuikScat satellite, are benefiting a wide range of users, from those who sail the seas to those responsible for managing their precious resources. -

Principal Hydrologic Responses to Climatic and Geologic Variability in the Sierra Nevada, California

Posted By dane307 in Hydrology

Sierra Nevada snowpack is a critical water source for California's growing population and agricultural industry. However, because mountain winters and springs are warming, on average, precipitation as snowfall relative to rain is decreasing, and snowmelt is earlier. The changes are stronger at mid-elevations than at higher elevations. The result is that the water supply provided by snowpack is di -

Holocene Climates and Connections between the San Francisco Bay Estuary and its Watershed: A Review

Posted By maplover in Fluid Mechanics

Climate over the watershed of the San Francisco Bay Delta estuary system varies on a wide range of space and time scales, and affects downstream estuarine ecosystems. The historical climate has included mild to severe droughts and torrential rains accompanied by flooding, providing important lessons for present-day resource managers. Paleoclimate records spanning the last 10,000 years, synthesize -

Climate Models Overheat Antarctica, New Study Finds

Posted By goopsgoops in Hydrology

Computer analyses of global climate have consistently overstated warming in Antarctica, concludes new research by scientists at the National Center for Atmospheric Research (NCAR) and Ohio State University. The study can help scientists improve computer models and determine if Earth's southernmost continent will warm significantly this century, a major research question because of Antarctica's po -

2050 How soon is now?

Posted By aqua in Miscellaneous

A 2004 Pentagon report warns the U.S.A. President that an abrupt climate change will take Planet Earth on the brink of anarchy and nuclear war for access to basics resources like food and water.

'2050 How soon is now?' approaches the issue of Climate Change from the perspective of the consequences for our civilization and the short time we have to react. -

Geoengineering Could Slow Down The Global Water Cycle

Posted By Kaveh in Hydrology

As fossil fuel emissions continue to climb, reducing the amount of sunlight hitting the Earth would definitely have a cooling effect on surface temperatures. However, a new study from Lawrence Livermore National Laboratory, led by atmospheric scientist Govindasamy Bala, shows that this intentional manipulation of solar radiation also could lead to a less intense global water cycle. Decreasing sur -
