Scientists say they are seeing cicadas pop up across the Midwest and South this year – including in the Chicago area.
The periodical cicada brood – known as Brood 13 – arrives once every 17 years to engage in a month-long mating ritual. During that ritual, they shed their skin, and in the words of researchers,"sing."
The 17-year cicadas appeared in 1973, then again in 1990, and once more in 2007. So that means they shouldn't be back until May of next year – 2024.The good news is cicadas are harmless, and not too many of the periodical cicadas will be around this year. The periodical cicadas are different form annual dog-day cicadas – which come around every year in the Chicago area, and sing at dusk and sometimes even during the day between July and early October.

Greenland Ice Sheet melting faster than previously thought, scientists sayScientists have determined that in the last 10 to 20 years of steady global warming, the ocean has played an 'important role' in the evolution of glaciers, Eric Rignot, professor of system science at the University of California, Irvine, and author of the study, told ABC News. Melting at the interface between ice sheets and the ocean in the Arctic is much more extensive than previously estimated, according to a study published Monday in Proceedings of the National Academy of Sciences. What is happening at the grounding line -- the junction between a grounded ice sheet and the ocean -- led the researchers to discover much more melting that previously thought at Petermann Glacier in Greenland, according to the paper.
