By Elizabeth Howell 5 November 2021 (Space.com) – A new NASA video highlights the giant ozone hole that opened over Antarctica this year. A cold Southern Hemisphere winter, and possible effects of global warming, have caused the hole to grow to its 13th-largest extent since 1979. The ozone depletion you see in the NASA video is monitored by three […]
By Molly Taft 2 November 2021 (Gizmodo) – A new satellite image of Turkey’s Lake Tuz is gorgeous—and, if you know more about what it’s portraying, worrying. The stunning capture from the European Space Agency’s Sentinel-2 satellite shows Turkey’s second-largest lake has completely dried up this year, exposing a haunting expanse of salt. While Lake Tuz, one of the world’s largest saltwater lakes, […]
By Andrew Roth 20 July 2021 MOSCOW (The Guardian) – Every morning and evening for the last few days, shifts of young villagers have headed out into the taiga forest around Teryut with a seemingly impossible task: to quell the raging fires that have burned closer and closer for a month, shrouding this remote eastern […]
By Adam Voiland 23 July 2021 (NASA) – While plumes of wildfire smoke from western North America have passed over the northeastern U.S. and Canada multiple times each summer in recent years, they often go unnoticed. That is because smoke that spreads far from its source typically moves at a fairly high altitude—between 5 and 10 kilometers—as […]
By Lucy Kafanov, Leslie Perrot, and Eliott C. McLaughlin 17 July 2021 Great Salt Lake, Utah (CNN) – Great Salt Lake is also known as America’s Dead Sea — owing to a likeness to its much smaller Middle Eastern counterpart — but scientists worry the moniker could soon take new meaning. Human water consumption and […]
By Kate Larsen, Hannah Pitt, Mikhail Grant, and Trevor Houser 6 May 2021 (Rhodium Group) – Each year Rhodium Group provides the most up-to-date global and country-level greenhouse gas (GHG) emissions estimates through the ClimateDeck (a partnership with Breakthrough Energy). In addition to our preliminary US and China GHG estimates for 2020, Rhodium provides annual estimates of economy-wide emissions—including all […]
26 May 2021 (NOAA) – […] The atmospheric abundance of CO2 has increased by an average of 1.85 ppm per year over the past 41 years (1979-2020). This increase in CO2 is accelerating — while it averaged about 1.6 ppm per year in the 1980s and 1.5 ppm per year in the 1990s, the growth rate increased to […]
By Raja Razek and Alaa Elassar 4 April 2021 (CNN) – Response teams in Manatee County Florida are trying to prevent a “real catastrophic flood situation” in the Piney Point reservoir area, Gov. Ron DeSantis said Sunday after taking an aerial tour the area. The governor assured the public that the water being discharged to […]
By Ben Quinn 24 March 2021 (The Guardian) – A scientist with one of the world’s largest chemical firms took the difficult decision to speak out publicly when “a new generation” of managers rejected concerns about a mass-produced weedkiller that he had been expressing for decades. Going public has been a “relief”, says toxicologist Jon […]
By Luana Souza 24 March 2021 (Bloomberg News) – Illegal gold and diamond mining is proliferating in Brazil’s Amazon rain forest and threatening South America’s largest group of native people who still live in relative isolation, the Yanomami. Criminal mining groups are encroaching on the indigenous territory that straddles Brazil and Venezuela, polluting rivers, bringing diseases […]
![Annual Greenhouse Gas Index (AGGI), 1750-2020. For 2020, the AGGI was a record high 1.47, representing an increase in total direct radiative forcing of 47 percent since 1990. This increase in CO2 is accelerating — while it averaged about 1.6 ppm per year in the 1980s and 1.5 ppm per year in the 1990s, the growth rate increased to 2.4 ppm per year during the last decade (2009-2020). Pre-1978 changes in the CO2-equivalent abundance and AGGI based on the ongoing measurements of all greenhouse gases reported here, measurements of CO2 going back to the 1950s from C.D. Keeling [Keeling et al., 1958], and atmospheric changes derived from air trapped in ice and snow above glaciers [Machida et al., 1995, Battle et al., 1996, Etheridge, et al., 1996; Butler, et al., 1999]. Equivalent CO2 atmospheric amounts (in ppm) are derived with the relationship between CO2 concentrations and radiative forcing from all long-lived greenhouse gases.
