As temperatures rise due to increasingly severe global warming, the effect of high temperatures on wildlife, including green sea turtles, is one of the issues that must be addressed to ensure the conservation of biodiversity. In the current study, we found that green sea turtle cell death due to apoptosis occurred at 37 °C, which suppressed cell proliferation. We also found that high temperature-induced heat stress led to the accumulation of DNA damage in green sea turtle cells.

Increased global nitrogen (N) and phosphorus (P) inputs caused by human activities can significantly impact methane (CH) uptake in terrestrial ecosystems. Forest soils, as the largest CH sink among terrestrial ecosystems, play a crucial role in mitigating global warming. However, the effects of long-term N and P additions on CH sink and the associated microbial mechanisms in subtropical forest soils remain unclear.

Climate warming and frequent incidents of extreme high temperatures are serious global concerns. Heat stress induced by high temperature has many adverse effects on animal physiology, especially in aquatic poikilotherms. Chinese mitten crab (Eriocheir sinensis) is sensitive to high temperatures, this study evaluated the harmful effects of heat stress on the neurotoxicity, intestinal health, microbial diversity, and metabolite profiles.

Shifting community assembly dynamics are an underappreciated mechanism by which warming will alter plant community composition. Germination timing (which can determine the order in which seedlings emerge within a community) will likely shift unevenly across species in response to warming. In seasonal environments where communities reassemble at the beginning of each growing season, changes in germination timing could lead to changes in seasonal priority effects, and ultimately community composition.

Natural gas (NG) is a promising alternative to diesel for sustainable transport, potentially reducing GHG and air quality emissions significantly. However, the GHG benefits hinge on managing methane slip, the unburned methane in the exhaust of NG engines, which carries a significant global warming potential. The CH slip from NG engines is highly dependent on engine type and operation, and effective greenhouse gas emission mitigation requires that the actual operation of real-world engines is monitored.
