Concentrations of the three main greenhouse gases – carbon dioxide, methane, and nitrous oxide – reached record highs in 2021. The annual increase in methane concentration was the highest on record. Real time data from specific locations show levels of the three gases continued to increase in 2022.
Global mean temperature in 2022 is currently estimated to be 1.15 ± 0.13 °C above the 1850-1900 average. The eight years 2015 to 2022 are likely to be the eight warmest years on record, with 2022 most likely to be 5th or 6th warmest.
La Niña conditions have continued with short interruptions since late 2020 and are expected to continue through late 2022. This would mark the third consecutive year of La Niña. Such a triple-dip La Niña is unusual and has kept global temperature low for the second year in a row.
Sea level continued to rise in 2022, reaching a new record high. Since January 2020, global mean sea level has risen by nearly 10mm, approximately 10% of the overall rise in sea level since satellite measurements began in 1993.
