New Climate Change Forecasts for the Nation
The most current projections of climate change and its impacts, as well as
recommendations for future actions, are available in a new U.S. Global
Change Research Program report. Climate change is currently happening at
an unprecedentedly rapid rate, and there is substantial confidence that
human activities are the primary cause. Climate changes and impacts
include a mean global temperature increase of 1.5 degrees Fahrenheit over
the past 50 years, frequent downpours and flooding, less winter
precipitation and snowpack in the mountains, sea level rise along our
coastlines, and glacier melt and permafrost thaw. Conclusions are broken
down for every region of the country, so you can see how climate is
changing in your own area. For a podcast interview about this report with
Virginia Burkett, USGS Chief Scientist for Global Change Research, listen
to USGS CoreCast
episode 99. For more information, visit the
United States Global Change Research Program Web site or contact
Jessica Robertson at
jrobertson@usgs.gov or (703) 648-6624.
Energy in the Arctic: Quantities, Ownership and New
Insight
Do you want new insight on the future of petroleum? How about geographic
details of the Arctic’s energy assets or insight on potential
environmental impacts in this area? New maps and interpretations, detailed
statistical results and descriptions of the research methodology are now
available regarding the Arctic’s energy resources. This research builds
upon the initial results of the USGS Circum-Arctic Resource Appraisal that
were released last summer, estimating that 13 percent of the world’s
undiscovered oil and 30 percent of undiscovered gas may be north of the
Arctic Circle. Interest in the Arctic is growing due to the recent retreat
of polar ice and the rising global demand for energy, so check out the new
research published in the journal
Science at. For more information, please contact Jessica
Robertson at jrobertson@usgs.gov
or (703) 648-6624.
Paddling for a Purpose: Tribal Journey in the Salish
Sea
The Coast Salish Nation and the USGS will embark on their second Tribal
Journey together from July 21-August 3 to study and improve water
resources in the Salish Sea. The media are invited to attend a celebration
of blending traditional knowledge with USGS science as canoes land on
Lummi Shores, WA on July 26. Water quality has deteriorated significantly
across the Puget Sound and the Strait of Georgia in recent decades. Last
year, water quality probes towed behind canoes identified areas with
unexpected water quality patterns, which may threaten many habitats and
ecosystem functions. This year, the project will study even more features
and will collect information critical for identifying causes of water
quality impacts and detecting trends during changes in land use and
climate. Check out last year’s maps, videos and photos by visiting the
2008 Coast Salish
Water Quality Project Web site. Journalists are welcome to set up
interviews with USGS scientists throughout the journey by contacting
Jennifer LaVista at jlavista@usgs.gov
or (703) 648-4432.
What Makes Fireworks Colorful?
Every Independence Day, Americans celebrate by gazing into the night sky
to watch spectacular fireworks displays. But what makes the colors in
fireworks so vivid? It’s minerals — each color is produced by a specific
mineral compound. Bright greens are from barium, blues come from copper
and yellows require sodium. More colors are made by mixing compounds. The
role of minerals in fireworks is just one example of our society’s
reliance on minerals for making products ranging from automobiles to
toothpaste. Want to know more? Visit the
Minerals Information Web site
for statistics on production, trade and resources for about 90 mineral
commodities from around the world. Also, enjoy fun mineral facts at the
Mineral Facts and
FAQ's Web site. For more information, contact Jessica Robertson at

Weeding Out Alien Invaders
It’s the growing season, and it seems as if nothing grows better than
invasive plants. But where will they appear, and can they be stopped? The
ability to map current species distributions and forecast which habitats
are most vulnerable to these alien invasions is now possible. USGS
scientists, in collaboration with Colorado State University and NASA,
developed a new tool that helps public land managers document, map and
predict the spread of harmful invasive species of plants (as well as
animals and diseases). This will help decision makers take appropriate
preventive measures where possible. Invasive Species Awareness Week, from
July 5-11, is the perfect time to learn more about the "Advanced Invasive
Species Modeling Room," and you can do so at the
Developing Ecological Forecasting Models Web site. You can also
contact Tom Stohlgren at
stohlgrent@usgs.gov
or
(970) 491-1980.
Corals in Decline — USGS to the Rescue
An estimated 20 percent of the world’s coral reefs are damaged, perhaps
irreparably. They could be progressively lost over the coming decades as
they continue to face harmful fishing practices, disease, coastal
developments, pollutants and greenhouse gas emissions, which lead to
increased sea level, ocean acidification, and water temperatures. Coral
ecosystems are worth hundreds of billions of dollars to the global
economy, and millions of people rely on healthy coral ecosystems for food,
recreation, storm protection and more. Some 25 percent of all marine life
is also linked directly to coral ecosystems. Additional research is needed
to more accurately explain natural processes and forecast human-induced
change. The USGS provides decision makers with assessments of coral
ecosystem history, ecology, vulnerability and resiliency to help them
develop mitigation and adaptation strategies. As Coral Reef Awareness Week
(July 20-24) approaches, it’s the perfect time to learn more by viewing
the USGS
Coral Science Plan (PDF) or listening to a
podcast interview on coral
reefs. You can also contact Gary Brewer at
gbrewer@usgs.gov or (304) 724-4507.
Pinpointing Drought Coast to Coast
Drought is a devastating natural hazard, affecting more people than any
other natural hazard and costing the United States an average of $6 to 8
billion annually. By being able to monitor droughts, society and its
decision makers can take action early to mitigate the detrimental affects
and thereby minimize costs. For that reason, the Vegetation Drought
Response Index, also known as VegDRI, is a valuable addition to the field
of drought monitoring. VegDRI combines information from historical and
current satellite observations, climate indicators, ecological settings,
and soil characteristics to show drought’s effect on vegetation. This
system is particularly important to the agricultural community and can
provide detailed information over broad regions of land as it reassesses
the entire conterminous 48 states every other week. Ultimately, VegDRI
promises to make drought response and mitigation more effective. For more
information, visit the
Vegetation
Drought Response Index Web site or contact Jon Campbell at
joncampbell@usgs.gov or (703)
648-4180.
How a Major Piece of the Rockies Took Shape
The geologic history of Colorado’s Rocky Mountain National Park turns out
to be a bit different than scientists previously thought. A new USGS map
and report have updated information, covering over 90 percent of the park
and nearby wilderness areas, national recreation areas and national
forests. Insight on the area’s history helps in understanding hazards such
as landslides and flooding; resources such as metals, oil and gas, coal,
construction materials, and water; and land-use considerations including
development, dam/reservoir construction, resource extraction, and
conservation. The Rocky Mountains’ high, rugged appearance is described as
the long-term result of geologic processes such as uplift, faulting,
volcanism, weathering, glaciation and erosion. A better understanding of
current climate conditions and impacts is also possible with new insight
on climate change’s influence on the formation of the Rockies and other
landforms. To view the map, visit the
Geologic Map of the Estes Park
30’ x 60’ Quadrangle, North-Central Colorado Web site. For more
information, contact Heidi Koontz at
hkoontz@usgs.gov or (303) 202-4763.
Pesticides Found in Florida Lakes
Pesticide compounds and elevated levels of nitrate have been found in
lakes in Florida’s Lake Wales Ridge region. This is a major citrus
producing area where pesticides are applied multiple times per year. When
that’s combined with a wet climate, soils lacking in materials to filter
or break down substances, and porous drinking water aquifers, the water
system must be closely watched. Even though none of the pesticide and
nitrate concentrations in lake samples exceeded benchmarks for drinking
water or aquatic life, the combined effects of these chemicals may be of
concern. It is important to continue efforts in early detection,
monitoring, and understanding of the chemicals and their impacts. The USGS
is helping state agencies develop a sampling network to detect
contaminants as they enter the aquifers. A new
report was authored by
the USGS in cooperation with the Florida Department of Environmental
Protection and the Southwest Florida Water Management District. For more
information, visit the
Monitoring
Pesticides in Water: Lake Wales Ridge Web site or contact Anne
Choquette at achoq@usgs.gov or (615)

Story Seeds (points to ponder or
investigate)
What Can You Make With 80 Tons of Copper?
Copper is a metal for the ages — it was used for coins
and ornaments around 8000 B.C., and 80 tons of copper were hammered to a
thickness of two U.S. pennies during the 1880s to create the Statue of
Liberty. Copper was one of the first metals ever extracted and used by
humans, and today it has a variety of domestic, industrial, and
high-technology applications. A new
USGS publication
highlights how and where copper resources form and concentrate in Earth’s
crust; how this mineral interacts with the environment to affect human and
ecosystem health; trends in the supply and demand for copper in the
domestic and international markets; and where future copper resources
might be found. For more information, contact Jessica Robertson at
jrobertson@usgs.gov or (703)
648-6624.
Want Information About Protected U.S. Lands?
Fifteen percent of the United States’ land area (more than 347 million
acres) is highly protected conservation lands, and understanding
conservation efforts in these areas just became a lot easier! Information
about the more than 22,000 protected areas in this acreage is now
available online at the
Protected Areas Database of the United States. This comprehensive
database is essential for species and habitat conservation decisions and
other open space management decisions. It provides the most current
information on geographic boundaries, land classification (federal, state,
city or private), land owner or manager, management designation and much
more. This database is hosted by the USGS National Biological Information
Infrastructure. For more information, contact John Mosesso at
john_mosesso@usgs.gov or (703)
648-4079.
Protecting Tortoises by Understanding Their Habitat
The recovery of the threatened desert tortoise population depends on the
protection and conservation of the species’ natural habitat. Scientists
use habitat modeling as an essential tool to simulate and predict the
potential distribution of the desert tortoise and its habitats. This
allows land managers to better plan conservation efforts, monitor changes
in the quantity and quality of available habitat, and minimize and
mitigate disturbances such as urbanization and infrastructure, off-road
vehicle use, wildfires and more. For additional information, visit
Modeling Potential Habitat of the Desert Tortoise. You can also
contact Ken Nussear at
knussear@usgs.gov or (702) 564-4515, or Todd Esque at
todd_esque@usgs.gov or (702)
564-4506.
Climate Change in the Rocky Mountains
Summer seems to be coming earlier in the Rocky Mountain West, and climate
change may be the culprit. USGS scientists are studying ecosystem
responses to climatic variability in the Western United States to
understand what’s happening now and what might occur in the future.
Research includes climate impacts to native fish, wildlife species and
mountain ecosystems; how climate may control burn patterns of forest
fires; and how climate change may impact the denning times of grizzly
bears. The USGS is also developing a web-based system where federal
agencies can share resources and information regarding variability and
change throughout the Northern Rockies landscape. To learn more, see
NOROCK Climate Change & Ecosystem Science (PDF) or contact Jeff
Kershner at jkershner@usgs.gov or
(406) 994-5304.
USGS in NEON: Illuminating Environmental Trends
Nationwide
Large-scale environmental influences such as climate change, land use, and
invasive species are fast becoming top-priority concerns for public land
and resource managers. To help prepare for and mitigate adverse impacts to
our natural treasures, managers need scientifically sound ecological
forecasts of what is likely to happen. The USGS and others are
collaborating with NEON Inc. to develop the National Ecological
Observatory Network (NEON), sponsored by the National Science Foundation.
NEON calls for 60 observation stations across the continental U.S.,
Hawaii, and Puerto Rico to identify and track ecological change. USGS
involvement includes helping develop protocols for collecting data on
long-term, large-scale environmental changes. Standard field procedures
improve the quality of data used to forecast ecosystem responses to such
changes. For more information visit NEON
or contact Tom Stohlgren at
stohlgrent@usgs.gov or (970) 491-1980.
