The Drying of the Sahara Desert

paulg — Thur, 08 May 2008 22:08:40 GMT

Hi Everybody,

This comes to us from Kelly Beatty...very interesting!

Paul

The Drying of the Sahara:

The transition of northern Africa from a

"green Sahara" to the world's largest hot

desert was a slow transition rather than an

abrupt change, and the extremely arid

landscape of the Sahara today was established

about 2,700 years ago, researchers say. Most

of the physical records documenting the

evolution of the Saharan landscape have been

lost to time, but by studying one of the

largest Saharan lakes, Lake Yoa in remote

Northern Chad, an international research team

led by Stefan Kropelin was able to construct

a continuous and well-dated record of climate

and ecosystem change in that location over

the past 6,000 years. The study took into

account data from high-resolution sediment

sequencing and geochemical readings, as well

as biological indicators such as pollen,

spores, and the remains of aquatic organisms.

The results provide evidence that the

transformation of the Saharan landscape over

the past 6,000 years involved a gradual

reduction in the abundance of tropical

vegetation, followed by the loss of grass

cover, and the eventual establishment of the

modern desert plant community. These findings

are in opposition with some previous modeling

results that indicate a rapid vegetation

collapse and sudden end to the African Humid

Period. A related Perspective by Jonathan A.

Holmes discusses the disparities and

similarities between the results of this

experiment and other associated studies.

May 5th meteor shower

paulg — Tue, 29 Apr 2008 18:02:52 GMT

Hi Everybody,

The annual Eta Aquarid meteor shower is usually not talked about, as it's a better southern hemisphere show. However, this year's predawn sky will be moonless, so it's worth letting your viewers know about looking low in the east-southeast in the pre-dawn hours of May 5th.

Although we see fewer of these meteors than our friends in the "other" hemisphere, these meteors are particularly spectacular (sometimes with long lasting tails) and are worth looking for.

Wishing you clear skies,

NHC to Use NCAR's VORTRAC for Hurricane Season

Emilie — Fri, 11 Apr 2008 13:50:18 GMT

The National Center for Atmospheric Research (NCAR) just put out a press release that the The National Hurricane Center will implement VORTRAC (Vortex Objective Radar Tracking and Circulation). VORTRAC continually monitors landfalling storms in the United States. The system, which relies on existing coastal Doppler radars, provides details on hurricane winds and central pressure every six minutes, indicating whether a hurricane is gathering strength in its final hours before reaching shore.

Discoveries and Breakthroughs Inside Science did a story on this in Sept. 2007. Check out our website (http://www.aip.org/dbis/stories/2007/17103.html) for ideas on how you can use this information for a "station scientist" segments during hurricane season.

April 2, 2008
The Moon's stellar companion
Twilight sets a perfect stage Tuesday evening, April 8, when our Moon passes the beautiful Pleiades star cluster.

WAUKESHA, WI The night sky will deliver one of its greatest spectacles April 8 when a crescent Moon will appear against the colorful tapestry of a twilit sky. Add the Pleiades star cluster to the mix and the stage is set for a performance no skygazer will want to miss.

Mark your calendar for Tuesday, April 8. Head outside no later than an hour or so after sunset (roughly 8:30 p.m. local daylight time), and look to the west. Your eyes should land immediately on the slender crescent Moon, oriented with its cusps standing nearly straight up from the horizon.

Binoculars will reveal a stunning sight. "Point them at the Moon," says Astronomy Senior Editor Richard Talcott. "The bright Pleiades star cluster sparkles like a clutch of tiny diamonds accenting the primary jewel the Moon."

Flooding and Climate Change

Media Advisory Friday, March 21, 2008

Flooding and Climate Change Resources for Journalists and Station Meteorologists

Ongoing flooding in the mid-western and north-eastern United States is consistent with expectations of heavier rainfall and snowfall events related to a warming climate as projected in the consensus reports issued last year by the Nobel-prize winning Intergovernmental Panel on Climate Change (IPCC).

IPCC author Kevin Trenberth of the National Center for Atmospheric Research (NCAR) notes that we've recently seen a 20% increase in the heaviest 1% of precipitation events in the U.S. while we've seen about a 7% increase in total precipitation - meaning that more of the rain is coming in the form of heavy downpours - precipitation is less frequent but more intense, which tends to yield both wetter and drier conditions at different times and places.

Trenberth also notes that the water holding capacity of the atmosphere goes up 4% per degree F increase in temperature, and this is observed over oceans but slightly less 2-3% over land. With more water vapor in the atmosphere that is directly attributable to global warming, there is an increase in rainfall of 4 to 8% as a result. . The past winter has had above average temperatures in the southeast and thus an extra moisture supply into storms farther north.

Global warming increases the odds that the United States will see increases in extreme weather. The current flooding is an example of the kind of extreme weather that is exacerbated by a warming climate. The heavy precipitation is an example of the kind of extreme weather that United States is likely to witness even more frequently, if climate change goes unchecked.

Copies and summaries of the IPCC reports are available at www.ipcc.ch.

Excerpts of the IPCC reports related to heavy precipitation and flooding are presented below and are also available at www.ipccinfo.com along with links to resources available at NOAA, NCAR and NASA.

IPCC Consensus Statements on Flooding, Heavy Precipitation, and Climate Change

Key passages from the report by the IPCC's Working Group I:
The Physical Science Basis issued February 2, 2007:
Observed changes

"At continental, regional, and ocean basin scales, numerous long-term changes in climate have been observed. These include changes in Arctic temperatures and ice, widespread changes in precipitation amounts, ocean salinity, wind patterns and aspects of extreme weather including droughts, heavy precipitation, heat waves and the intensity of tropical cyclones."

"The frequency of heavy precipitation events has increased over most land areas, consistent with warming and observed increases of atmospheric water vapour."

Projections of future changes

"It is very likely that hot extremes, heat waves, and heavy precipitation events will continue to become more frequent." (In IPCC terminology, "very likely" means a probability greater than 90 percent and "likely" means a probability greater than 66 percent.)

"Since the there is an improving understanding of projected patterns of precipitation. Increases in the amount of precipitation are very likely in high-latitudes, while decreases are likely in most subtropical land regions...continuing observed patterns in recent trends."

Scientific certainty

"There is now higher confidence in projected patterns of warming and other regional-scale features, including changes in wind patterns, precipitation, and some aspects of extremes and of ice."

Key passages from the report by the IPCC's Working Group II
Impacts, Adaptation and Vulnerability" Issued April 6:

"Based on growing evidence, there is high confidence that the following types of hydrological systems are being affected around the world:

* increased run-off and earlier spring peak discharge in many glacier- and snow-fed rivers;

Current knowledge about future impacts global

"The most vulnerable industries, settlements and societies are generally those in coastal and river flood plains, those whose economies are closely linked with climate-sensitive resources, and those in areas prone to extreme weather events, especially where rapid urbanisation is occurring ."

"Where extreme weather events become more intense and/or more frequent, the economic and social costs of those events will increase, and these increases will be substantial in the areas most directly affected. Climate change impacts spread from directly impacted areas and sectors to other areas and sectors through extensive and complex linkages ."

Current knowledge about future impacts - North America

"Warming in western mountains is projected to cause decreased snowpack, more winter flooding, and reduced summer flows, exacerbating competition for over-allocated water resources ."

Key passages from the report by the IPCC Climate Change 2007: Synthesis Report
Issued November 17th:

The Long-Term Perspective; Reasons for Concern

"The five 'reasons for concern' identified in the TAR remain a viable framework to consider key vulnerabilities.

* Risks of extreme weather events. Responses to some recent extreme events reveal higher levels of vulnerability than the TAR. There is now higher confidence in the projected increases in droughts, heatwaves, and floods as well as their adverse impacts.

Volunteers across the Nation to Track Climate Clues in Spring Flowers

Starting this week, citizen-scientist volunteers will be able to help track climate change by observing and recording the timing of flowers and foliage.

Project BudBurst, operated by the University Corporation for Atmospheric Research (UCAR) and a team of partners including the U.S. Geological Surveys USA National Phenology Network, allows U.S. students, gardeners, and other citizens to enter their observations into an online database that, over time, will give researchers a more detailed picture of global climate change.

The project, which will be launched on Feb. 15, will operate year-round so that early- and late-blooming species in different parts of the country can be monitored throughout their life cycles. Project BudBurst (http://www.budburst.org) builds on a pilot program carried out last spring, when a thousand participants recorded the timing of the leafing and flowering of hundreds of plant species in 26 states.

The Chicago Botanic Garden, University of Montana, and the USA National Phenology Network (USA-NPN) are collaborators on Project BudBurst, which was funded in part with a grant from the U.S. Bureau of Land Management and the National Fish and Wildlife Foundation. The project is also supported by the National Science Foundation and Windows to the Universe (http://www.windows.ucar.edu/), a UCAR-based Web site that will host the project online as part of its citizen science efforts.

Climate change may be affecting our backyards and communities in ways that we dont even notice, says project coordinator Sandra Henderson of UCARs Office of Education and Outreach. Project BudBurst is designed to help both adults and children understand the changing relationship among climate, seasons, and plants, while giving the participants the tools to communicate their observations to others. Based on the success of last years pilot program, this project is capturing the publics imagination in a way we never expected.

Project Budburst is one of the citizen-science partnerships of the newly created USA-NPN (www.usanpn.org), which is managed by the U.S. Geological Survey, and includes partners such as the National Science Foundation, the University of Arizona, the U.S. Fish and Wildlife Service and many other agencies. The goal of the USA-NPN is to engage governmental agencies, environmental networks and field stations, educational institutions, and mass participation by citizen scientists in collecting phenological information on plants and animals.

Phenology is the study of periodic plant and animal life cycle events and how these are influenced by seasonal and interannual variations in climate, said Dr. Jake Weltzin, executive director of the USA-NPN. Examples of phenological events include the timing of leafing and flowering, agricultural crop stages, insect emergence, and animal migration.

By observing these cycles through time, researchers can better understand and predict global climate change, and monitor drought conditions, wildfire risk, invasive species, and the spread of infectious diseases, said Weltzin. In the long-term -- and with enough data -- such information can help us better understand, mitigate and adapt to ongoing and future climate change.

The USA-NPN will begin enlisting the help of working professional scientists and training citizen volunteers for more intensive plant-phenology monitoring later this spring. In addition, Weltzin said USA-NPN is closely collaborating with other already-existing networks such as Project Budburst to maximize the data collected.

How Project Budburst Works

As described on the Project BudBurst webpage, each participant selects one or more plants to observe. Participants begin checking their plants at least a week before the average date of budburst -- the point when the buds have opened and leaves are visible. After budburst, participants continue to observe the tree or flower for later events, such as the first leaf, first flower and, eventually, seed dispersal. When participants submit their records online, they can view maps of these phenological events across the United States.

Along with the partners noted above, Project BudBurst collaborators include the Plant Conservation Alliance and the universities of Arizona; California, Santa Barbara; Wisconsin-Milwaukee; and Wisconsin-Madison.

on the morning of February 1st, Venus and Jupiter will be slightly over apart low in the eastern sky before dawn. That's close enough to cover both with your fingertip at arm's length, and also close enough to fit easily in a single telescopic field at 50. at that magnification, you can easily see the disks of both planets, together with at least three of Jupiter's four brightest moons.

they'll still be close together for a few days, and a thin crescent Moon joins the show on feb. 3rd and 4th.

you don't even have to get up all that early 6 a.m. should give you plenty of time at most locations. but make sure the view toward east is reasonably clear.

BREAKING NEWS NEW AGU STATEMENT ABOUT CLIMATE CHANGE

paulg — Thur, 24 Jan 2008 15:48:10 GMT

American Geophysical Union
24 January 2008
AGU Release No. 08-03

Contact: Peter Weiss
+1 (202) 777-7507
pweiss@agu.org

AGU Revises Position on Climate Change

WASHINGTON - A statement newly released by the world's largest
scientific society of Earth and space scientists--the American Geophysical
Union, or AGU--updates the organization's position on climate change: the
evidence for it, potential consequences from it, and how to respond to it.

The statement is the first revision since 2003 of the climate-change position
of the AGU, which has a membership of 50,000 researchers, teachers, and
students in 137 countries. The society adopted the statement at a meeting of
AGU's leadership body, the AGU Council, in San Francisco, California, on
14 December 2007. AGU position statements expire in four years, unless
extended by the Council.

Following is the text of the revised statement (also available online at
http://www.agu.org/sci_soc/policy/positions/climate_change2008.shtml ).

Human Impacts on Climate

The Earth's climate is now clearly out of balance and is warming. Many
components of the climate system--including the temperatures of the
atmosphere, land and ocean, the extent of sea ice and mountain glaciers, the
sea level, the distribution of precipitation, and the length of seasons--are
now changing at rates and in patterns that are not natural and are best
explained by the increased atmospheric abundances of greenhouse gases and
aerosols generated by human activity during the 20th century. Global
average surface temperatures increased on average by about 0.6 degrees
Celsius over the period 1956-2006. As of 2006, eleven of the previous
twelve years were warmer than any others since 1850. The observed rapid
retreat of Arctic sea ice is expected to continue and lead to the
disappearance of summertime ice within this century. Evidence from most
oceans and all continents except Antarctica shows warming attributable to
human activities. Recent changes in many physical and biological systems
are linked with this regional climate change. A sustained research effort,
involving many AGU members and summarized in the 2007 assessments of
the Intergovernmental Panel on Climate Change, continues to improve our
scientific understanding of the climate.

During recent millennia of relatively stable climate, civilization became
established and populations have grown rapidly. In the next 50 years, even
the lower limit of impending climate change--an additional global mean
warming of 1 degree Celsius above the last decade--is far beyond the range
of climate variability experienced during the past thousand years and poses
global problems in planning for and adapting to it. Warming greater than 2
degrees Celsius above 19th century levels is projected to be disruptive,
reducing global agricultural productivity, causing widespread loss of
biodiversity, and--if sustained over centuries--melting much of the
Greenland ice sheet with ensuing rise in sea level of several meters. If this 2
degrees Celsius warming is to be avoided, then our net annual emissions of
carbon dioxide must be reduced by more than 50 percent within this
century. With such projections, there are many sources of scientific
uncertainty, but none are known that could make the impact of climate
change inconsequential. Given the uncertainty in climate projections, there
can be surprises that may cause more dramatic disruptions than anticipated
from the most probable model projections.

With climate change, as with ozone depletion, the human footprint on Earth
is apparent. The cause of disruptive climate change, unlike ozone depletion,
is tied to energy use and runs through modern society. Solutions will
necessarily involve all aspects of society. Mitigation strategies and
adaptation responses will call for collaborations across science, technology,
industry, and government. Members of the AGU, as part of the scientific
community, collectively have special responsibilities: to pursue research
needed to understand it; to educate the public on the causes, risks, and
hazards; and to communicate clearly and objectively with those who can
implement policies to shape future climate.

Adopted by AGU Council, December, 2003
Revised and Reaffirmed, December, 2007

2007 Among Hottest Years on Record:

NASA Scientists Release Global Temperature Analysis

An analysis of 2007 global temperature data undertaken by scientists at Goddard Institute for Space Studies (GISS), New York, reveals that 2007 is tied with 1998 as the second hottest year on record. The unusual warmth of 2007 is noteworthy because it occurs at a time when solar irradiance is at a minimum and the equatorial Pacific Ocean has entered the cool phase of its El Nio-La Nia cycle.

The greatest warming in 2007 occurred in the Arctic. Global warming has a larger affect in polar areas, as the loss of snow and ice leads to more open water, which absorbs more sunlight and warmth. The large Arctic warm anomaly of 2007 is consistent with observations of record low Arctic sea ice in September 2007.

The eight warmest years in the GISS record have all occurred since 1998, with 2005 ranking as the hottest. Barring a large volcanic eruption, NASA scientists predict that a record global temperature exceeding that of 2005 can be expected within the next two to three years.
