Long-term sea level rise could cost Washington, D.C., billions
A study by University of Maryland Civil and Environmental Engineering Professor Bilal Ayyub, Haralamb Braileanu, and Naeem Qureshi, of the Clark School of Engineering’s Center for Technology and Systems Management, looks at possible long-term effects of projected sea level rise on Washington, D.C., real-estate property and government infrastructure. They conclude that over the next 100 years, con ... read more >>
Groundwater inundation doubles previous predictions of flooding with future sea level rise
Scientists from the University of Hawaii at Manoa (UHM) published a study today in Nature Climate Change showing that besides marine inundation (flooding), low-lying coastal areas may also be vulnerable to "groundwater inundation," a factor largely unrecognized in earlier predictions on the effects of sea level rise (SLR). Previous research has predicted that by the end of the century, sea level ... read more >>
Why Antarctic sea ice cover has increased under the effects of climate change
The first direct evidence that marked changes to Antarctic sea ice drift have occurred over the last 20 years, in response to changing winds, is published this week in the journal Nature Geoscience. Scientists from NERC's British Antarctic Survey (BAS) and NASA's Jet Propulsion Laboratory (JPL), Pasadena California explain why, unlike the dramatic losses reported in the Arctic, the Antarctic sea ... read more >>
Climate modeler identifies trigger for Earths last big freeze
For more than 30 years, climate scientists have debated whether flood waters from melting of the enormous Laurentide Ice Sheet, which ushered in the last major cold episode on Earth about 12,900 years ago, flowed northwest into the Arctic first, or east via the Gulf of St. Lawrence, to weaken ocean thermohaline circulation and have a frigid effect on global climate.
Now University of Massachuset

Enhanced melting of Northern Greenland in a warm climate
In a new study from the Bjerknes Centre for Climate Research, scientists show how the northern part of the Greenland ice sheet might be very vulnerable to a warming climate.
The study is based on simulations with a state of the art global climate model and a dynamic ice sheet model of the last interglacial warm period. This period (~126 thousand years before present) is the most recent in Earth'

North Carolina Sea Level Rise Accelerating, Researchers Report
This summer the North Carolina Senate passed a bill banning researchers from reporting predicted increases in the rate of sea level rise. But the ocean, unbound by legislation, is rising anyway — and in North Carolina this rise is accelerating, researchers reported here yesterday (Nov. 6) at the annual meeting of the Geological Society of America.
On the coast of North Carolina and at other so-c

Global Warming Supercharged by Water Vapor?
Evaporated H2O is a known greenhouse gas—a gas that absorbs and re-emits infrared radiation in Earth's atmosphere, thereby increasing temperatures (see our global warming fast facts).
But only now has a study uncovered evidence that water vapor is a major public enemy in Europe.
According to a team of Swiss scientists, heat from other greenhouse gases is causing more water to evaporate, rel

The surface energy balance and actual evapotranspiration of the transboundary Indus Basin estimated ...
The surface energy fluxes and related evapotranspiration processes across the Indus Basin were estimated for the hydrological year 2007 using satellite measurements. The new ETLook1.0 remote sensing model infers information on actual Evaporation (E) and actual Transpiration (T) from combined optical and passive microwave sensors, which can observe the land-surface even under persistent overcast c ... read more >>
Parameterization of Rainfall Models with Emphasis on Extremes
Temporal rainfall is usually represented as a series of storms with different duration D and average intensity , separated by dry periods. Inside each storm, rainfall intensity fluctuates, producing different average values in different intervals of duration d {less than or equal to} D. We consider storm models of this type to predict the distribution of the annual maximum of . Of special importa ... read more >>
Projected climate change impacts on the hydrology and temperature of Pacific Northwest rivers
A Dominant River Tracing based streamflow and Temperature (DRTT) model was developed by coupling stream thermal dynamics with a source-sink routing model. The DRTT model was applied using 1/16 degree (~6 km) resolution gridded daily surface meteorology inputs over a ~988,000 km2 Pacific Northwest (PNW) domain to produce regional daily streamflow and temperature simulations from 1996 to 2005. The ... read more >>
