The year 2023 was the warmest year on record, the World Meteorological Organization (WMO) confirmed in a report released this week, titled “”Our State of the Climate Report 2023.”
Some highlights from the report
#Global average near-surface temperature was at 1.45 °Celsius (with a margin of uncertainty of ± 0.12 °C) above the pre-industrial baseline.
It was approximately 1.45 ± 0.12 °C warmer than the pre-industrial (1850-1900) average.
#The shift from La Niña, which lasted from mid-2020 to early 2023, to fully developed El Niño conditions by September 2023 likely explains some of the rise in temperature from 2022 to 2023.
#Carbon dioxide: 417.9ppm ± 0.2 = 150% of pre-industrial levels.
Methane: 1923±2 ppb = 266% of pre-industrial levels.
Nitrous oxide: 335.8±0.1 ppb = 124% of pre-industrial levels.
#It was approximately 1.45 ± 0.12 °C warmer than the pre-industrial (1850-1900) average.
#Around 90% of the excess energy that accumulates in the earth system due to increasing concentrations of greenhouse gases, goes into the ocean.
#The sea has risen approximately 3.4 ± 0.3 mm per year over the past 30 years of the satellite altimeter record.
Global mean ocean pH has been steadily declining at rates not seen for at least the past 26,000 years.
