Spring plant phenology and false springs in the conterminous US during the 21st century

Highlights Spring onset will occur earlier throughout the conterminous US by the year 2100. Projections of earlier spring onset indicate that recent historical trends may continue, but not everywhere. The averaging of many models canceled out the effects of the simulated internal variability and emphasized the role of greenhouse-forced climate change. Future changes in false … More Spring plant phenology and false springs in the conterminous US during the 21st century

U.S. Winter Outlook: Strong El Niño sets the stage. NOAA Climate Prediction Center – Seasonal Outlook

Strong El Niño conditions remain in place across the equatorial Pacific Ocean as represented by both ocean and atmospheric data. The ongoing El Niño event is expected to peak in strength in late autumn or early winter with seasonal average sea surface temperature (SST) anomalies in the Nino 3.4 region near or exceeding +2.0 degrees … More U.S. Winter Outlook: Strong El Niño sets the stage.

Hydrologic issues associated with nuclear waste repositories

A schematic of the hydrologic issues related to the disposal at Yucca Mountain. Abstract Significant progress in hydrology, especially in subsurface flow and solute transport, has been made over the last 35 years because of sustained interest in underground nuclear waste repositories. The present paper provides an overview of the key hydrologic issues involved, and … More Hydrologic issues associated with nuclear waste repositories

Increased threat of tropical cyclones and coastal flooding to New York City during the anthropogenic era

“The flood risk for New York City due to tropical cyclones and their resultant storm surges has increased significantly during the last millennium. Mean flood heights increased by >1.2 m from ∼A.D. 850 to A.D. 2005 due to rising relative sea levels. Additionally, there were increases in the types of tropical cyclones that produce the … More Increased threat of tropical cyclones and coastal flooding to New York City during the anthropogenic era
