NASA uses Satellites to Help Forecast Wildlife Migration in Yellowstone National Park

 

NASA - National Aeronautics and Space AdministrationMountain View, CA – The research project looked specifically at how long the growing season lasts in Yellowstone  National Park, from snowmelt in spring to first snowfall in autumn, and the vegetation that covers the land in between.

The satellite data revealed that the season for vegetation growth has been getting longer, likely a result of climate change decreasing the severity of winters and warming average temperatures overall.

Studying national parks is helpful for this type of climate research, because human land use is restricted in these spaces.

A study using data from two NASA Earth science satellites reveals that the season for vegetation growth has been getting longer in Yellowstone National Park. Likely a result of climate change decreasing the severity of winters and warming average temperatures overall, this effect on the productivity of grasslands has contributed to the growing number of bison in the park.

National Christmas Tree’s rich History

 

US Capitol Christmas Tree and Other Forerunners to the National (Community) Christmas Tree

US National Park ServiceWashington, D.C. – The first community Christmas celebration in Washington, D.C. was on December 24th, 1913. The Christmas tree and related pageantry occurred on the East Plaza of the US Capitol on Christmas Eve. It was meant as a celebration for all of Washington, rich and poor, young and old, although a special emphasis was placed on the children.1

The forty-five minute program, replete with angel figures in white robes, nativity tableaux, carols, and Boy Scouts waving American flags, was modeled largely on community celebrations in other cities.

Lamar Alexander: Senate Committee Approves “Restore Our Parks Act”, Biggest Boost to National Parks in 50 Years

 

U.S. SenateWashington, D.C. – United States Senator Lamar Alexander (R-Tenn.) today said a bill he sponsored, along with three of his colleagues, to reduce the maintenance backlog at our nation’s 419 national parks, including the Great Smoky Mountains National Park, is “one step closer to becoming law.” 

“This legislation could do more to restore our national parks than anything that has happened in the last half century, and the reason we need to restore them is so Americans can enjoy the 419 sites – from the National Mall in Washington, D.C., to the Great Smoky Mountains National Park to the Grand Canyon – for generations to come,” Senator Alexander said.

Lamar Alexander, Sherrod Brown, Introduce Bipartisan Legislation to Create National Network of African American Burial Grounds

 

U.S. SenateWashington, D.C. – U.S. Senators Lamar Alexander (R-TN) and Sherrod Brown (D-OH) have introduced bipartisan legislation to create a voluntary, nationwide network of African American burial grounds and to provide federal assistance to ensure the burial sites are preserved and maintained for future generations.

“Earlier this year, I joined a group of leaders to visit Union Baptist Cemetery in Cincinnati, and see all the work that was needed to restore the burial ground to the place of honor that it should be,” said Senator Brown.

NASA maps California Fires to help agencies on the ground

 

NASA Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – For the past two weeks NASA scientists and satellite data analysts have been working every day producing maps and damage assessments that can be used by disaster managers battling the Woolsey Fire near Los Angeles and the Camp Fire in Northern California.

The agency-wide effort also deployed a research aircraft over the Woolsey Fire on November 15th to identify burned areas at risk of mudslides in advance of winter rains expected in the area.

Spearheaded by NASA’s Disasters Program in the Earth Science Division, the team produces a variety of data products largely derived from satellite observations, including maps showing the locations of active fires, damage caused by fires, and burned areas that are susceptible to landslides and mudslides.

NASA research shows Smoke from Wildfires can Impact Climate more than previously thought

 

Written by Joe Atkinson
NASA Langley Research Center

NASA - National Aeronautics and Space AdministrationHampton, VA – The 2017 wildfire season is well underway in the United States with thousands of acres scorched already in Georgia and Florida alone, according to the National Park Service. New research using data collected during NASA airborne science campaigns shows how smoke from this type of wildfire worldwide could impact the atmosphere and climate much more than previously thought.

The study, led by researchers at the Georgia Institute of Technology, found brown carbon particles released into the air from burning trees and other organic matter are much more likely than previously thought to travel to the upper levels of the atmosphere, where they can interfere with rays from the sun – sometimes cooling the air and at other times warming it.
