Extreme climatic events such as droughts, heat waves, and cold spells not only modify hydro-meteorological conditions but also alter the underlying characteristics (e.g., wildfires due to droughts changing the vegetation cover). Intense human activities, such as river channel modifications, afforestation, deforestation, industrialization, and urbanization, further amplify the variability of...
Elevated surface ozone concentrations in China are posing a significant threat to both human health and crop yields. Extreme heat can greatly exacerbate ozone pollution through both complex chemical and physical processes. For example, extreme heat is often accompanied by stagnant weather conditions, which can lead to the accumulation and subsequent elevation of ozone.
A study led by the Leibniz Centre for Agricultural Landscape Research (ZALF) and published in the journal Ecological Economics provides important insights into the future of food labeling in the EU. By analyzing expert opinions from the food industry, the study identifies a broad consensus on the need for new food labels to encourage farmers to provide more ecosystem services.
Legislators love bundling things together. It lets them accomplish more with less hassle and attempt to make legislation more appealing to a broader group. But a new study in the journal Climatic Change suggests that this can sometimes backfire. The authors found that pairing climate policies with other policies does not necessarily increase their popular appeal, and can actually reduce public...
