Peatlands are one of the world’s biggest carbon sinks. Despite covering just 3-4% of Earth’s land surface, they’re thought to store more carbon per area than the world’s forests combined. In honor of World Peatland Day on June 2 here's three recent Mongabay stories on this critical ecosystem...

I think about this map a lot. www.bloomberg.com/graphics/201...
This is a cartogram map of the United States depicting land use by different categories. The map distorts state shapes to represent proportional land usage. Key land use types include cow pasture/range (covering much of the central U.S.), private and federal timberland in the Pacific Northwest, corporate timberland in the Southeast, and urban housing/commercial areas in the Northeast. Other categories include agriculture (livestock feed, wheat exports, ethanol/biodiesel, cotton), protected lands (national parks, federal wilderness, state parks), and infrastructure (railroads, airports, highways). Additional specialized land uses include wildfires, golf courses, Christmas tree farms, and maple syrup production.

Although NOAA's page on atmospheric CO2 levels has vanished, you can still get this vital information from Ralph Keeling's team at the Scripps Institution of Oceanography, UC San Diego keelingcurve.ucsd.edu Please follow bsky.app/profile/keel... for updates and share Don't let science be hidden
A graph of atmospheric carbon dioxide concentrations at the Mauna Loa observatory, Hawaii, from 1958 to 4th February 2025. It shows carbon dioxide levels rising at an accelerating rate over the decades. This is known to be due to emissions of carbon dioxide from human activity, mainly fossil fuel burning but also deforestation. The first CO2 concentration value in March 1958 was 315 parts per million (ppm). The latest daily value is 426 ppm. The graph also shows a seasonal cycle of a few ppm within each year, which is known to be linked to the growing season in the northern hemisphere causing a temporary uptake of carbon in spring and summer and release in autumn. The graph is produced routinely by the Scripps Institution of Oceanography, UC San Diego.

(b) Probability distributions of 24-hr TC intensification rates for the initial period (1979–1999) in blue, later period (2000–2020) in orange and the difference in green. The mean TC intensification rates for the two periods and the corresponding sample sizes, and the mean difference including the p-value, are shown in the figure legend. A Student's t-test for difference of means is used to ascertain statistical significance. The error bars have been estimated using the Monte Carlo method of repeated random sampling. Note that the data have been sub-sampled to ensure that distributions of storm state are statistically similar for the two periods (see “Methods”). TC track data are based on IBTrACS (Knapp et al., 2010).
