You can track the rise of carbon dioxide and greenhouse gases on our Global Climate Dashboard.

We wrote about the importance of reducing our carbon dioxide emissions, even if other countries don’t do the same and explained why, if carbon dioxide hits a new high every year, isn’t every year hotter than the last. Carbon dioxide peaked at 424 parts per million in May at NOAA’s Mauna Loa Atmospheric Baseline Observatory, which is more than 50% higher than before the industrial era. According to the Global Carbon Budget report, there is an urgent need to significantly reduce emissions to meet global climate targets and avoid severe and deleterious effects of climate change.

In May 2023, carbon dioxide hit 424 ppm-a new record. At Mauna Loa, the highest monthly value each year occurs in May. The long-term trend of rising carbon dioxide levels is driven by human activities. The seasonal cycle of highs and lows (small peaks and valleys) is driven by Northern Hemisphere summer vegetation growth, which reduces atmospheric carbon dioxide, and winter decay, which increases it. This graph shows the station's monthly average carbon dioxide measurements since 1958 in parts per million (ppm). The modern record of atmospheric carbon dioxide levels began with observations recorded at Mauna Loa Observatory in Hawaii. Several heat waves impacted the United States this summer bringing life-threatening conditions to Puerto Rico, prolonged triple-digit heat to Texas in June, and record temperatures to portions of the Southwest in July. Meanwhile, the Arctic experienced a record-warm summer which contributed to the continued decline of sea ice across the region, according to this year’s Arctic Report Card. Antarctic sea ice experienced a record-low summer minimum AND record-low winter maximum this year. The oceans experienced record high temperatures globally for many months, which lead to a historic heat wave and widespread coral bleaching throughout the Florida Keys. There is an all but certain chance ( greater than 99%) that 2023 will rank as Earth’s warmest year on record according to NOAA’s long-term record. NOAA graph, based on data from NOAA National Centers for Environmental Information. Septembers have grown warmer at a rate of nearly 1 degree Fahrenheit (0.6 degrees Celsius) per century over the modern temperature record. September temperature compared to the 20 th-century average from 1850 to 2023. California gets another honorable mention this year, when former Hurricane Hilary in August caused the National Hurricane Center to issue its first ever tropical storm watch (and later warning) for the state. To date, the drought across the West has improved for many locations and California remains drought-free, according to the U.S.

This series of events significantly improved drought conditions across a large chunk of the western United States and provided California with 80 percent of their average seasonal snowpack.

Where best to start than in January? A series of NINE atmospheric rivers in the first few weeks of the year dropped FEET of rain and snow across California and other parts of the West Coast.

Places where precipitation was less than 100 percent of the 1991-2020 average are brown places where precipitation was 300 percent or more than average are blue-green.
