Figure 3: (a) The mean air-sea CO₂ flux density and (b) trend in the CO₂ flux density 1958–2019 in the historical simulation (simulation A) (c–f) The effects of the rising atmospheric CO₂ concentration and climate change on the trend in the CO₂ flux density obtained as the difference between two simulations with and without interannual variability and trends in the respective variable(s): (c) Atmospheric CO₂ concentration, (d) full climate variability and trends, (e) winds and (f) global warming. Positive values denote a trend toward more oceanic outgassing or less oceanic uptake, respectively. Hatched areas in (b–f) indicate a low significance of the trend (p-value > 0.05 applying a two-sided Wald Test with t-distribution).

My latest: Polar scientists warn that the White House and NSF are planning to terminate the Nathaniel Palmer, the only US research icebreaker capable of handling Antarctic extremes, this October.

So far the plan has seen minimal pushback from Congress.

They want to close the NOAA lab (GML) that brings you this, the most iconic time series in the environmental sciences.

gml.noaa.gov/ccgg/trends/

$A scientific line graph titled “Atmospheric CO₂ at Mauna Loa Observatory.” The graph displays the atmospheric carbon dioxide (CO₂) mole fraction measured in parts per million (ppm) from the year 1958 to 2025. The x-axis represents the year, ranging from 1958 to just past 2020. The y-axis represents CO₂ mole fraction in ppm, ranging from 310 to 430. The data is represented by a jagged red and black line that shows both seasonal fluctuations and a long-term upward trend. Key observations: CO₂ mole fraction starts at around 315 ppm in 1958. The graph shows a steady upward trajectory, with seasonal oscillations (up and down) superimposed on the trend. By 2025, the CO₂ level exceeds 420 ppm.
