A nuclear war between India and Pakistan could, over the span of less than a week, kill 50-125 million people—more than the death toll during all six years of World War II, according to new research.
A new study conducted by researchers from CU Boulder and Rutgers University examines how such a hypothetical future conflict would have consequences that could ripple across the globe. Today, India and Pakistan each have about 150 nuclear warheads at their disposal, and that number is expected to climb to more than 200 by 2025.
The picture is grim. That level of warfare wouldn’t just kill millions of people locally, said LASP atmospheric scientist Brian Toon, who led the research published today in the journal Science Advances. It might also plunge the entire planet into a severe cold spell, possibly with temperatures not seen since the last Ice Age.
How did the Red Planet get all of its clouds? LASP scientists may have discovered the secret: just add meteors.
Astronomers have long observed clouds in Mars’ middle atmosphere, which begins about 18 miles (30 kilometers) above the surface, but have struggled to explain how they formed.
Now, a new study, published on June 17 in the journal Nature Geoscience, examines those wispy accumulations and suggests that they owe their existence to a phenomenon called “meteoric smoke”—essentially, the icy dust created by space debris slamming into the planet’s atmosphere.
The University of Colorado Boulder’s cross-campus Grand Challenge initiative this week announced the selection of three new additions to its portfolio starting this fall. The call for proposals, which was announced in June, funded one large research initiative at approximately $1 million per year and two smaller projects at $250,000 per year, each for at least three years. LASP will collaborate on the research initiative and on one of the two smaller projects.
The selections augment the current Grand Challenge portfolio, building on the accomplishments of Earth Lab, Integrated Remote and In Situ Sensing (IRISS), the university’s space minor, and the Center for the Study of Origins.
A solar instrument package designed and built by LASP, considered a key tool to help monitor the planet’s climate, has arrived at NASA’s Kennedy Space Center in Florida for a targeted November launch.
The instrument suite is called the Total and Spectral solar Irradiance Sensor (TSIS-1) and was built for NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The contract value to LASP is $90 million and includes the dual instrument suite and an associated ground system to manage TSIS mission operations.
