Changing temperatures increase pesticide risk to bees

A new study suggests that climate change could lead to increased pesticide toxicity on bee populations and their pollination services. Environmental temperature can influence the degree to which pesticides affect bees' behavior, with certain temperatures causing a 'tipping point' in their ability to tolerate pesticide exposure.

Sea level rise poses particular risk for Asian megacities

A new study highlights Asian megacities like Chennai, Kolkata, Yangon, Bangkok, Ho Chi Minh City, and Manila as facing significant risks from sea level rise by 2100. The research incorporates natural sea level fluctuations to show how climate change amplifies this effect, leading to more frequent extreme flooding events.

Skin samples reveal where southern right whales feed

Researchers analyzed chemical isotopes in 1002 skin samples to study the distribution of southern right whales and long-term environmental changes in the Southern Ocean. The study shows that the whales' foraging grounds have shifted, reflecting changing prey distributions, and that climate change has driven recent shifts.

Climate change, urbanization drive major declines in L.A.’s birds

A new study reveals that climate change and urbanization have dramatically impacted bird populations in Los Angeles and the Central Valley. In L.A., more than one-third of bird species have declined over the past century, while the Central Valley saw a mix of winners and losers. The study used current and historical bird surveys to ana...

Study finds sinking tundra surface unlikely to trigger runaway permafrost thaw

Researchers used a high-performance computer simulation to study the impact of soil subsidence on permafrost thawing in the Arctic tundra. They found that uneven land subsidence leads to a drier landscape, which limits the process's acceleration through the end of the century.

Forest management will have a stronger effect than climate change on the supply of ecosystem services

Researchers from University of Jyväskylä found that forest management has a stronger effect on the supply of ecosystem services than climate change. The study suggests that forest management planning should account for biogeographic diversity, and climate change mitigation measures are particularly suited for northern Finland.

Devastating cost of future coastal flooding for many developing nations predicted in new study

A new study predicts devastating socioeconomic impacts of future extreme coastal flooding on developing nations caused by climate change. Without adaptation measures, the number of people affected could increase from 34 million in 2015 to 246 million by 2100, with expected annual damage costing over five percent of national GDP.

Lifestyles of the fast and slow (bacteria): in the wild, most live in the slow lane

A recent study published in The ISME Journal reveals that the majority of bacteria living in wild soil are slow growers, contrary to previous lab-based frameworks that suggested a dichotomy between fast and slow growing microbes. This finding highlights the importance of testing field-based ideas with data from nature.

Climate warming reduces organic carbon burial beneath oceans

A new study reveals that climate warming can reduce the burial of organic carbon beneath the ocean, leading to increased atmospheric carbon release. Researchers analyzed over 50 years of seafloor sediment cores, finding a significant decrease in organic carbon burial during certain periods, particularly during the mid-Miocene era.
