- More than half of the world's largest lakes and reservoirs are losing water — and climate change and human consumption are the main drivers. International researchers looked at 250,000 lake-area satellite images taken from 1992 until 2020 to examine 1,972 freshwater bodies. https://cires.colorado.edu/news/satellites-reveal-widespread-decline-global-lake-water-storage 69 comments science
- U.S. Fires Four Times Larger, Three Times More Frequent Since 2000. The amount of land burned each year increased from a median of 1,552 to 5,502 square miles (4,019 to 14,249 km2) in the West and from 465 to 1,295 square miles (1,204 to 3,354 km2) in the Great Plains. https://cires.colorado.edu/news/us-fires-four-times-larger-three-times-more-frequent-2000 12 comments science
- Air pollution triggered by use of common chemicals, fuels may kill 10 times more people than previously recognized. Air pollution caused by “anthropogenic secondary organic aerosol” causes 340,000-900,000 premature deaths. https://cires.colorado.edu/news/particles-paints-pesticides-have-deadly-impact 9 comments science
- Antarctica's northern George VI Ice Shelf experienced record melting during the 2019-2020 summer season compared to 31 previous summers of dramatically lower melt. Using satellite observations that detect meltwater on top of the ice, the researchers found the most widespread melt of any season https://cires.colorado.edu/news/extreme-melt-antarctica%E2%80%99s-george-vi-ice-shelf 4 comments science

- One sweaty, exercising person emits as many chemicals from their body as upto 5 sedentary people. Notably, those human emissions, including amino acids from sweat or acetone from breath, chemically combine with bleach cleaners to form new airborne chemicals with unknown impacts to indoor air quality https://cires.colorado.edu/news/sweat-bleach-gym-air-quality 27 comments science
- Unexpected Wildfire Emission Impacts Air Quality Worldwide. Nitrous acid levels in wildfire plumes worldwide are two to four times higher than expected. Hydroxyl radicals can degrade greenhouse gases, and can accelerate the chemical production of ozone pollution—by as much as 7 parts per billion https://cires.colorado.edu/news/unexpected-wildfire-emission-impacts-air-quality-worldwide 3 comments science
- An anticipated rise in carbon dioxide concentrations in our indoor living and working spaces by the year 2100 could lead to impaired human cognition. At 1400 ppm, CO2 concentrations may cut our basic decision-making ability by 25 percent, and complex strategic thinking by around 50 percent https://cires.colorado.edu/news/continued-co2-emissions-will-impair-cognition 164 comments science

- Violent crime rates rise in warmer winters in study that compared temperature and crime patterns since 1979. Researchers attribute the correlation to warmer weather leading to more people being out thus creating more opportunity for criminals. https://cires.colorado.edu/news/violent-crime-rates-rise-warmer-winters 4 comments science
