For those who did not get a chance to attend the Esri Geodesign Summit 2013 in Redlands, Calif. or who didn’t get to all of the sessions they would’ve liked to attend, here are a number of videos taken at the Summit of various talks.
Eric Webster, vice president of Exelis Weather Systems, talked recently about the company’s efforts along with NASA Langley Research Center to evaluate an Exelis instrument to determine its effectiveness for measuring CO2 from space.
DMC International Imaging (DMCii) is in the business of helping The Algerian Space Agency (ASAL) to predict the spread of locust plagues across North Africa. This effort is part of an aggressive approach to tackle the age-old problem of locust infestation using satellite imagery.
Geodesign is a set of techniques and enabling technologies for planning built and natural environments in an integrated process, including project conceptualization, analysis, design specification, stakeholder participation and collaboration, design creation, simulation, and evaluation (among other stages). “Geodesign is a design and planning method which tightly couples the creation of design proposals with impact simulations informed by geographic contexts.” – Wikipedia
After just having celebrated its 10th anniversary of service on 1 March 2012, ESA’s Envisat stopped sending data to earth. The last contact between the satellite and the ground station in Kiruna, Sweden was established on Sunday, ever since no data has been received. ESA’s mission control is working to re-establish contact with the satellite. Launched in 2002, Envisat has orbited Earth more than 50 000 times delivering thousands of images and other data used for example for climate change studies or natural disaster mitigation supporting more than 4000 projects in over 70 countries.

Already this spring there have been wildfires reported in the western states. According to the National Interagency Fire Center<http://www.nifc.gov/>, more than 82,000 wildfires occurred across 10 million acres in the U.S. last year.
According to several top scientists, the March heat wave that has shattered records across a wide swath of the U.S. bears some of the hallmarks of global warming.
In email conversations, those same scientific researchers who specialize in studying the role climate change plays in influencing individual extreme events — a burgeoning field known as “extreme event attribution” — said global warming may have made March’s soaring temperatures more likely to occur, although they add that natural variability has played a key role as well.

New estimates published this week in the online edition of the journal of Nature reports that Alaska glaciers have been shedding about 46 billion tons of ice each year, making America’s Arctic state the world’s single biggest contributor to glacier-fed sea level rise outside of Greenland or Antarctica. Still, Alaska remains a wee player in the global ice frappe, producing only about 8.5 percent of the world’s annual glacier shrinkage of 526 billion tons, according to the study, led by a team at the University of Colorado at Boulder.
