Animations, graphs and data from the USGS Open File Report 2013-1081 and the USGS project "Modeling Sea-Level Rise in San Francisco Bay Estuary" can be found online.

This photo shows a USGS researcher surveying marsh topography using a RTK GPS measuring unit, collecting data that was used to build the sea level rise forecasts for this USGS Open File Report.

USGS and University of Pennsylvania research shows that ancient pollen and charcoal preserved in deeply buried sediments in Egypt's Nile Delta document the region’s ancient droughts and fires, including a huge drought 4,200 years ago associated with the demise of Egypt's Old Kingdom, the era known as the pyramid-building time.

Despite some widespread similarities in climate change trends, climate change will affect specific water basins in the U.S. differently, based on the particular hydrologic and geologic conditions in that area. See how the Sprague River Basin, Oregon will be impacted.

USGS research of the Yukon River has had a long term goal of determining the source and fate of organic carbon transported by the river to the Bering Sea and ultimately the Arctic Ocean.

Results of recent analyses identified old carbonin the Yukon River, but also indicated that the chemical source was not derived from ancient plant material stored in the glacier, but from fossil fuel sources derived from atmospheric deposition. This add new complications to the interpretation of carbon sources and sinks in high latitudes and of the apparent sources of old organic carbon exported by arctic rivers.

]]> <![CDATA[Agricultural Field in the Great Plains Region of Montana]]> http://gallery.usgs.gov/photos/12_01_2011_bfv2YmkXXS_12_01_2011_0 Agricultural fields and an abandoned farmstead in eastern Montana in the Great Plains region. The Great Plains region of the United States has experienced significant land-use change since European settlement, with vast swaths of grasslands converted to agricultural lands. Access to water, technological changes, a growing biofuels industry, fluctuating demands for agricultural products, and government policies have resulted in periodic historical shifts in land use in the region and may drive major land-use changes in the next several decades. Land use and land management in the region have significant implications for carbon storage and greenhouse-gas fluxes.

]]> <![CDATA[Meltwater Stonefly (Lednia tumana)]]> http://gallery.usgs.gov/photos/03_15_2011_os37MaxLLG_03_15_2011_0 Loss of glaciers and snowpack due to climate warming in alpine regions is putting pressure on a rare aquatic insect, the meltwater stonefly, according to a U.S. Geological Survey study.

In the study, scientists with the USGS, the University of Montana, U.S. Fish and Wildlife Service and National Park Service illustrate that alpine aquatic insects can be ideal early warning indicators of climate warming in mountain ecosystems. The glaciers in Glacier National Park are predicted to disappear by 2030 and, as its name infers, the meltwater stonefly (Lednia tumana) prefers to live in the coldest, most sensitive alpine stream habitats directly downstream of disappearing glaciers, permanent snowfields and springs in the park.

Recent climates, and General Circulation Model results of future climates, portray this area as being suitable for the survival and expansion of Joshua trees.

During the prior year, this area received only 17 percent of its average precipitation and was 4 degrees F warmer than average -- conditions that are projected to become even more frequent in models of future climate. Seedlings and saplings in this southerly stand of Joshua trees are rare to non-existent.

Cerro Gaillardo stands to the left of the monument. The vegetation is Chihuahuan Desert Grassland that has a scattering of shrubs within it. The smaller shrubs are probably broom snakeweed; the larger shrubs are velvet mesquite. Elev. 4,000 ft. (D. R. Payne).

The mesquite, occurring here near the upper limits of its range, has remained short, probably as the result of catastrophic freezes that have visited the area. Bush muhly is found beneath some of the mesquites. (Raymond M Turner).
