All European airports were open this morning after ash concentrations over the continent dispersed, but ash may head back towards Portugal and Spain this afternoon, causing more problems.
Here we report a high-resolution molecular stratigraphic record of chlorin concentrations over the past 350,000 years in a sediment core from the subtropical Atlantic continental margin.
During the lateral injection process, each biosensor was visible from the surface as we varied the pH, glucose, and electrolyte concentrations over the ex vivo pig skin model.
We find that surface radiation trends, which have been largely explained by changes in atmospheric aerosol loading, caused a cooling that masked approximately one-third of the continental warming due to increasing greenhouse gas concentrations over the past half-century.
