By Adam Beam 17 June 2021 OROVILLE, Califorina (AP) – Each year Lake Oroville helps water a quarter of the nation’s crops, sustain endangered salmon beneath its massive earthen dam and anchor the tourism economy of a Northern California county that must rebuild seemingly every year after unrelenting wildfires. But the mighty lake — a […]
GLASGOW, UK, 4 June 2021 (Global Footprint Network) – Earth Overshoot Day 2021 lands on July 29, Councillor Susan Aitken, the Leader of Glasgow City Council, announced today on behalf of Global Footprint Network and the Scottish Environment Protection Agency (SEPA). “With almost half a year remaining, we will already have used up our quota […]
7 June 2021 (NOAA) – Atmospheric carbon dioxide measured at NOAA’s Mauna Loa Atmospheric Baseline Observatory peaked for 2021 in May at a monthly average of 419 parts per million (ppm), the highest level since accurate measurements began 63 years ago, scientists from NOAA and Scripps Institution of Oceanography at the University of California San Diego announced today. […]
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 Jessie Yeung and Esha Mitra 18 May 2021 NEW DELHI (CNN) – India was slammed on Monday by the strongest storm on record to reach its west coast, hampering authorities’ response to the Covid-19 crisis in some of the country’s hardest-hit regions. Tropical Cyclone Tauktae, a storm with wind speeds equivalent to a high-end Category 3 hurricane that […]
By Jeff Berardelli 8 May 2021 (CBS News) – Just a quick glance at the new U.S. Climate Normals maps published by the National Oceanic and Atmospheric Administration (NOAA) on Tuesday is enough for most climate scientists to say, “I told you so.” And it’s not just because the maps show a warmer and wetter […]
By Haley Brink 9 May 2021 (CNN) – The first tropical storm of the 2021 eastern Pacific hurricane season formed off the southwest coast of Mexico on Sunday. Tropical Storm Andres is the earliest tropical storm to ever form during the satellite era in the eastern Pacific, surpassing Adrian in 2017. Andres also holds the […]
By Mike Hixenbaugh, Suzy Khimm, Perla Trevizo, , Ren Larson, and Lexi Churchill 29 April 2021 HOUSTON (The Texas Tribune) – When Shalemu Bekele awoke on the morning of 15 February 2021, the townhouse he shared with his wife and two children was so cold, his fingers felt numb. After bundling up in extra layers, […]
By Graham Readfearn 22 April 2021 (The Guardian) – Twirling and meandering ocean currents that help shape the world’s climate have gone through a “global-scale reorganisation” over the past three decades, according to new research. The amount of energy in these ocean currents, which can be from 10km to 100km across and are known as […]
9 April 2021 (University of Gothenburg) – For the first time, researchers have been able to obtain data from underneath Thwaites Glacier, also known as the “Doomsday Glacier”. They find that the supply of warm water to the glacier is larger than previously thought, triggering concerns of faster melting and accelerating ice flow. With the […]
![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.
