A study published in Science Advances in 2022 stated that climate-caused changes in atmospheric rivers affecting California had already doubled the likelihood of megafloods since 1920—which can involve 100 inches (250 cm) of rain and/or melted snow in the mountains per month, or 25 to 34 feet (7.6 to 10.4 m) of snow in the Sierra Nevada—and ...
The 2.8 parts per million increase in carbon dioxide airborne levels from January 2023 to December, wasn't as high as the jumps were in 2014 and 2015, but they were larger than every other year since 1959, when precise records started. Carbon dioxide's average level for 2023 was 419.3 parts per million, up 50% from pre-industrial times.

The level of carbon dioxide increase between 2022 and 2023 was 12 percent higher than that of the last decade — and five times greater than that of the 1960s.
Atmospheric carbon dioxide (CO 2) concentrations from 1958 to 2023. The Keeling Curve is a graph of the annual variation and overall accumulation of carbon dioxide in the Earth's atmosphere based on continuous measurements taken at the Mauna Loa Observatory on the island of Hawaii from 1958 to the present day.
Subsequently, about 0.5 °C (0.90 °F) had occurred between 1950 and 2000, with about 0.4 °C (0.72 °F) since 1970, [44] largely matching the survey's "moderate global warming" scenario. 1980s In 1989, David H. Slade had surveyed 21 climate scientists, of whom 17 had expressed "a strong belief" in "the reality of a significant climate change".
An alarming new report from the Scripps Institution of Oceanography shows a record-breaking amount of CO2 in our atmosphere. According to NBC, the new tests show the level of carbon dioxide, a ...
The concentration of carbon dioxide (CO 2) in the atmosphere reached 427 ppm (0.04%) in 2024. [1] This is an increase of 50% since the start of the Industrial Revolution, up from 280 ppm during the 10,000 years prior to the mid-18th century. [2] [3] [4] The increase is due to human activity. [5]
