Abstract The Montreal Protocol and its successive amendments have been successful in curbing emissions of ozone-depleting substances potent greenhouse gases via production/consumption controls. Here we show that the radiative forcing equivalent effective chlorine from hydrochlorofluorocarbons has decreased 61.75 mW m − 2 321.69 ppt, respectively, since 2021, 5 years before most recent projected decrease. This important milestone demonstrates benefits for mitigating climate change...
Ethane-based chlorofluorocarbons and hydrochlorofluorocarbons can have multiple isomers that are difficult to separate using gas chromatography with detection by electron capture (GC-ECD) or even mass spectrometry (GC-MS). Examples include CFC-113 CFC-113a; CFC-114 CFC-114a; CFC-112 CFC-112a; HCFC-124 HCFC-124a.  As a result, atmospheric histories reported in the past most laboratories for more abundant isomer represent an ill-defined combination of both chemicals.  This is...
Abstract —J. Blunden and T. Boyer In 2023, La Niña conditions that generally prevailed in the eastern Pacific Ocean from mid-2020 into early 2023 gave way to a strong El Niño by October. Atmospheric concentrations of Earth’s major greenhouse gases—carbon dioxide, methane, nitrous oxide—all increased record-high levels. The annual global average carbon dioxide concentration atmosphere rose 419.3±0.1 ppm, which is 50% greater than pre-industrial level. growth 2022 was 2.8 fourth highest record...
Abstract —J. BLUNDEN, T. BOYER, AND E. BARTOW-GILLIES Earth’s global climate system is vast, complex, and intricately interrelated. Many areas are influenced by global-scale phenomena, including the “triple dip” La Niña conditions that prevailed in eastern Pacific Ocean nearly continuously from mid-2020 through all of 2022; regional phenomena such as positive winter summer North Atlantic Oscillation impacted weather parts Northern Hemisphere negative Indian dipole Southern Hemisphere; more...
