The ocean is becoming too loud for oysters

The upper panel depicts the coastal forest pre-tsunami, while the lower panel illustrates the forest post-tsunami. Each column represents the percentage decrease in coastal tree cover resulting from the tsunami event (1: no change, 5: 41-50%, 10: 91-100%). In cases where there was a 91-100% decrease in tree cover, indicated by the inset with the black frame in the bottom right image, nearly all trees were toppled by the tsunami. It is important to note that we magnified the satellite images/aerial photographs to assess the percentage decrease in coastal forest cover attributable to the tsunami event.

Mixed forests protect coastal areas from tsunami impacts better than monoculture forests

Artificial light is luring birds to cities and sometimes to their deaths

Five consecutive rainfall season failures in the Horn of Africa caused the region’s worst drought in 40 years (with Ethiopia, Kenya and Somalia particularly hard hit), contributing to reduced agricultural productivity, food insecurity and high food prices (WMO, 2023)

Drought data shows “an unprecedented emergency on a planetary scale”

Antarctic extremes ‘virtually certain’ as world warms

This map of red oak seed sources provides an example of a major threat to an important effort against climate change: major government and private funding is being invested in planting trees as a powerful tool to fight local and global warming. But new research in the journal Bioscience, from which this map is adapted, shows a troubling bottleneck that could threaten these efforts: U.S. tree nurseries don’t grow close to enough trees—nor have the species diversity needed—to meet ambitious planting goals.

Small isolated wetlands are pollution-catching powerhouses

A startling analysis from Globe at Night — a citizen science program run by NSF’s NOIRLab — concludes that stars are disappearing from human sight at an astonishing rate. The study finds that, to human eyes, artificial lighting has dulled the night sky more rapidly than indicated by satellite measurements. The study showcases the unique contributions that citizen scientists can make in essential fields of research. This graphic illustrates how the greater the amount of light pollution, and therefore skyglow, the fewer the stars that are visible.
