Mixed forests can reduce the risk of forest damage in warm climates
According to extensive data analyzed by researchers, mixed forests reduce damage to trees. Credit: Jan Bengtsson Forests with few tree species are at much greater risk of damage, and introduced lodgepole pines are particularly vulnerable. This is the result of a new study published in Ecosphere by researchers from Umeå University and the Swedish University of Agricultural Sciences (Uppsala). The…

Kitchen renovations could reduce household air pollution and save lives in rural China
Correlation analysis between kitchen characteristics (mechanical ventilation and separate kitchen in this study) and several influencing factors, including socio-economic and physical geographical factors. The heatmap on the left shows the correlation between each factor, and the diagonal bar chart shows the distribution of each factor. The numbers on the right are the corresponding correlation coefficients between those factors. Credit: Environmental…

Research: Even if warming is kept below 1.5°C, wildfires will significantly reduce the amount of carbon absorbed by land.
The percentage of burned area at 1.5°C and 2.0°C for each GFED region will change from the current time. Credit: Nature Geoscience (2024). DOI: 10.1038/s41561-024-01554-7 One of the objectives of the Paris Agreement was to “continue our efforts” to keep global warming below 1.5°C, but even this ambitious goal will continue to grow as wildfires become more intense and frequent.…
