A new Special Report (https://doi.org/10.1093/biosci/biaf175) published in the journal BioScience warns that long-term ecological and evolutionary research faces severe threats from lack of recurring funding and governmental/institutional support, to data manipulation and political interference, even as these studies become more crucial for addressing issues of broad societal importance, such as biodiversity loss and climate change.

MIT scientists identified a key atmospheric condition that determines how hot and humid a midlatitude region can get, and how intense related storms can become. The results may help climate scientists gauge a region’s risk for humid heat waves and extreme storms.

This special issue examines the multifaceted impact of climate change on business and finance, bringing together eight studies that explore how climate risks, opportunities, policies, and sentiment shape corporate behavior, investment decisions, and market dynamics. Key findings reveal that state ownership and environmental regulations significantly influence corporate environmental investment, while climate opportunity exposure can lower firms’ cost of capital in emerging markets. The research also highlights how climate policy uncertainty drives ESG performance improvements, and how both physical and transition climate risks amplify volatility in cryptocurrency markets. These insights underscore the growing integration of climate considerations into financial decision-making and point to actionable strategies for firms, investors, and policymakers navigating a climate-conscious economy.

In a paper published in SCIENCE CHINA Earth Sciences, a team of researchers conducted a comprehensive analysis of historical changes in the frequency and spatial extent of hot droughts at multiple timescales across global land areas, as well as anthropogenic influences on these changes. They also showed that hot droughts at different timescales are projected to increase in the future. Findings of this study can be useful for developing adaptation strategies to cope with threats from extremes in a warmer future.
