2020 tied for warmest year on record, NASA analysis shows — ScienceDaily

Earth’s global average surface temperature in 2020 tied with 2016 as the warmest year on record, according to an analysis by NASA. Continuing the planet’s long-term warming trend, the year’s globally averaged temperature was 1.84 degrees Fahrenheit (1.02 degrees Celsius) warmer than the baseline 1951-1980 mean, according to scientists at NASA’s Goddard Institute for Space […]

Broiling 2020 was the hottest year ever, NASA climate scientists say

2020 was a dumpster fire in more ways than one: The planet was literally hotter than ever before, with the year ranking alongside 2016 as the planet’s hottest since record-keeping began in 1880, NASA scientists recently reported. Researchers with the National Oceanic and Atmospheric Administration (NOAA) concluded in a separate assessment that 2020 was the […]

Life expectancy at birth will shorten by more than one year — ScienceDaily

The COVID-19 pandemic, which claimed more than 336,000 lives in the United States in 2020, has significantly affected life expectancy, USC and Princeton researchers have found.

Machine learning could lop a year off technology design cycle — ScienceDaily

If everything moved 40,000 times faster, you could eat a fresh tomato three minutes after planting a seed. You could fly from New York to L.A. in half a second. And you’d have waited in line at airport security for that flight for 30 milliseconds. Thanks to machine learning, designing materials for new, advanced technologies […]
