Attribution and projection of the compound extreme event based on the risk-based approach. (a) GEV distributions of the compound index in the Hist2020 (red) and HistNat2020 (blue) simulations from the HadGEM3-GA6-N216 model. The dashed and solid lines represent the intensities of the 2016 and 2020 events, respectively. The gray line shows the fraction of attributable risk (FAR; see y-axis on the right side of the panel). (b) The FAR value (bottom axis,…

Credit: Unsplash/CC0 Public Domain Anthropogenic aerosols—aerosols originating from human activity—and greenhouse gases, or GHGs, have helped modulate the storage and distribution of heat in oceans since the industrial age. Isolating and quantifying the effects of both forcers using coupled climate model simulations, a University of California, Riverside-led team has found that anthropogenic aerosols and GHGs have played…

Vanadium has been widely recognized as a…

Desert dust was assumed to be the primary contributor to elevated air pollution across the Middle East. Now, an international team of scientists including researchers from KAUST has shown that pollution from anthropogenic sources contributes to health risks and is an…

The replacement of vegetation zone toward to high-altitudes. It is about 167m lift in the vertical dimension when the temperature increases 1°C. Accordingly, vegetation redistribution and species migration will take place. Note that the altitudes of the three representative vegetation zones, that is, subtropical forest, temperate forest, and alpine tundra are according to the references (Colwell et al., 2008; Díaz-Varela et al., 2010; Jump et al., …
