The reduced net carbon uptake over Northern Hemisphere land causes the close-to-normal CO2 growth rate in 2021 La Niña
La Niña climate anomalies have historically been associated with substantial reductions in
the atmospheric CO2 growth rate. However, the 2021 La Niña exhibited a unique near …

Analysis of oil and gas ethane and methane emissions in the southcentral and eastern United States using four seasons of continuous aircraft ethane measurements
In the last decade, much work has been done to better understand methane (CH4)
emissions from the oil and gas (O&G) industry in the United States. Ethane (C2H6), a gas …
