Washington, D.C. – Hot and dry. NASA says these are the watchwords for large fires. While every fire needs a spark to ignite and fuel to burn, it’s the hot and dry conditions in the atmosphere that determine the likelihood of a fire starting, its intensity and the speed at which it spreads. Over the past several decades, as the world has increasingly warmed, so has its potential to burn.
Since 1880, the world has warmed by 1.9 degrees Fahrenheit, with the five warmest years on record occurring in the last five years. Since the 1980s, the wildfire season has lengthened across a quarter of the world’s vegetated surface, and in some places like California, fire has become nearly a year-round risk.
Pasadena, CA – NASA’s newest carbon dioxide-measuring mission to launch into space, the Orbiting Carbon Observatory-3 (OCO-3), has seen the light. From its perch on the International Space Station, OCO-3 captured its first glimpses of sunlight reflected by Earth’s surface on June 25th, 2019.
Just weeks later, the OCO-3 team was able to make its first determinations of carbon dioxide and solar-induced fluorescence – the “glow” that plants emit from photosynthesis, a process that includes the capture of carbon from the atmosphere.
Washington, D.C. – NASA says that for more than a billion people, Asia’s high mountain ranges, Himalaya, Karakoram, and Hindu Kush, are the names of their most reliable water source.
Snow and glaciers in these mountains contain the largest volume of freshwater outside of Earth’s polar ice sheets, leading hydrologists to nickname this region the Third Pole. One-seventh of the world’s population depends on rivers flowing from these mountains for water to drink and to irrigate crops.

Washington, D.C. – A NASA-led, international study finds Asia’s high mountain glaciers are flowing more slowly in response to widespread ice loss, affecting freshwater availability downstream in India, Pakistan and China. Researchers analyzed almost 2 million satellite images of the glaciers and found that 94 percent of the differences in flow rates could be explained by changes in ice thickness.
For more than a decade, satellite data have documented that the glaciers were thinning as the melt rates on their top surfaces increased.
Austin Peay State University (APSU)
Clarksville, TN – Smartphone photos are fine for most tourists, but when Austin Peay State University (APSU) student Amir Elraheb first experienced the splendor of Madrid, Spain, he pulled out his watercolors to truly capture the city.
“It’s sort of like a photograph, but when you are painting you have to pay attention to the details of whatever you’re looking at so much harder, so scenes are engrained in my head,” Elraheb, an Austin Peay State University foreign language major, said.
American Heart Association reports Heart disease, Stroke less widespread among Foreign-Born vs. U.S.-Born Adults
Journal of the American Heart Association Report
Dallas, TX – Foreign-born adults living in the United States had a lower prevalence of coronary heart disease and stroke than U.S.-born adults in nationally representative data spanning 2006-2014, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.

Nashville, TN – This month, House Speaker Pro Tempore Curtis Johnson (R-Clarksville), State Representative Jay Reedy (R-Erin), and the Tennessee Department of Education announced that Montgomery County Schools has received district growth funding to support education initiatives in Montgomery County.
Specifically, Montgomery County received $3,566,500.
This funding is a direct result of a Republican-led effort to not only fully fund education in Tennessee but also provide an additional $18 million to towards school district growth.
These significant investments in many Tennessee school districts will allow growing schools to maintain the necessary resources, so that they can continue offering quality education for our state’s young leaders.
Tampa, FL – Gas prices seemed to find level ground over the weekend after increasing for more than two weeks. Before the weekend, gas prices rose an average of 12 cents in 19 days, nationwide; 13 cents in 14 days, in Florida; 13 cents in 18 days, in Georgia; and 14 cents in 20 days, in Tennessee.
“Gas prices rose the wave of rising oil prices last week, pushing pump prices slightly higher in some regions before eventually stalling out over the weekend,” said Mark Jenkins, spokesman, AAA The Auto Club Group.
Clarksville, TN – Shiloh Industries is gearing up for new product production in Clarksville-Montgomery County’s Corporate Business Park with the first new die cast machine expected to be installed this week.

Greenbelt, MD – The movements of the stars and the planets have almost no impact on life on Earth, but a few times per year, the alignment of celestial bodies has a visible effect.
One of these geometric events — the spring equinox — is just around the corner, and another major alignment — a total solar eclipse — will be visible across America on August 21st, with a fleet of NASA satellites viewing it from space and providing images of the event.
To understand the basics of celestial alignments, here is information on equinoxes, solstices, full moons, eclipses and transits:
