Heat waves and severe air pollution are increasingly occurring together across northern India, exposing millions of people to multiple environmental hazards at the same time. A new study finds that this growing threat is driven not only by local pollution sources, but also by climate-related changes in large-scale atmospheric circulation that favor both extreme heat and intensified particle pollution.

A new study published in Advances in Atmospheric Sciences shows that greening in China generally cools the local climate with more rainfall over southern and northeastern China, while greening in India tends to produce warming and less rainfall. The Co-occurring greening in China and India yields uniform climate feedbacks across over half global lands, producing cooler and wetter southern China, cooler western Eurasia, and warmer northern North America.

In the pollination evolution of angiosperms, oil flowers represent a highly unique group. Approximately 2000 species across 11 families secrete lipids (rather than traditional nectar) through specialized oil glands as floral rewards. Oil-offering plants rely heavily on specialized oil-collecting bees for pollination, with females using specialized brushes on their legs to collect lipids for nest-building and larval provisioning. Among them, Macropis (Melittidae) is a classic genus of oil-collecting bees known for their strict oligolecty on the genus Lysimachia (Primulaceae). However, for decades, studies in Europe and North America generally assumed that Macropis bees primarily associate with oil-secreting loosestrifes, where males also patrol for mates. Prior to this work, specialized visits by Macropis bees—especially males—to non-oil, nectar-bearing Lysimachia species had not been documented.

Greenland ice records human efforts to cut pollution. But after about 1990, different chemical pollutants diverge to different paths.

A new study helps explain why unusually “hot and dry” summers can still occur frequently over a region that has undergone long-term warming and wetting.
