An India-Pakistan nuclear war could kill millions, threaten global starvation

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.

From concept to satellite instrument in three months

In the wake of an unfortunate event, two University of Colorado Boulder (CU) graduate students have accomplished a remarkable feat in space science: they’ve designed and built a new satellite instrument in less than three months.

Bennet Schwab, a graduate student in the Department of Aerospace Engineering Sciences, and Robert Sewell, a graduate student in the Department of Physics, have been on an emotional roller coaster ride over the past few months. One extended peak in that ride came during the preparation and launch of the NASA Miniature X-ray Solar Spectrometer, or MinXSS-2, CubeSat on December 3, 2018, and the subsequent successful observations of X-rays from the Sun. This initial success was soon followed by a setback, when there was a loss of communication with the CubeSat on January 7, 2019.
