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 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 […]
7 April 2021 (NOAA) – Levels of the two most important anthropogenic greenhouse gases, carbon dioxide and methane, continued their unrelenting rise in 2020 despite the economic slowdown caused by the coronavirus pandemic response, NOAA announced today. The global surface average for carbon dioxide (CO2), calculated from measurements collected at NOAA’s remote sampling locations, was […]
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 […]
2 March 2021 (IEA) – The Covid-19 crisis in 2020 triggered the largest annual drop in global energy-related carbon dioxide emissions since the Second World War, according to IEA data released today, but the overall decline of about 6% masks wide variations depending on the region and the time of year. After hitting a low in […]
Dr. Robert Rohde 17 March 2021 (Twitter) – Due in large part to the burning of fossil fuels, carbon dioxide levels in the atmosphere have now risen about 50 percent above the preindustrial level. At recent rates of growth, we would reach double the preindustrial by around 2075. Dr. Robert Rohde on Twitter
By Eimi Yamamitsu 10 March 2021 IWAKI, Japan (Reuters) – With a moment of silence, prayers, and anti-nuclear protests, Japan on Thursday mourned about 20,000 victims of the massive earthquake and tsunami that struck Japan 10 years ago, destroying towns and triggering nuclear meltdowns in Fukushima. Huge waves triggered by the 9.0-magnitude quake – one […]
By Laura Sanicola and Erwin Seba 21 February 2021 NEW YORK/HOUSTON (Reuters) – The largest U.S. oil refiners released tons of air pollutants into the skies over Texas this past week, according to figures provided to the state, as refineries and petrochemical plants in the region scrambled to shut production during frigid weather. An arctic […]
![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.
