Large solar proton event explains 774-775 CE carbon-14 increase

Tree ring records indicate that in 774-775 CE, atmospheric carbon-14 levels increased substantially. Researchers suggest that a solar proton event may have been the cause. In solar proton events, large numbers of high-energy ...

Evaluating the seismic risk of mineral carbon sequestration

Geologic carbon sequestration, in which carbon is captured and stored underground, has been proposed as one way to mitigate the climatic effects of carbon dioxide emissions. One method of geologic carbon sequestration is ...

Distinguishing drought and water scarcity
