    Clouds A spectrum of droplet sizesH. Jesse SmithMarine stratocumulus clouds, pictured here in northeastern Norway, contain water droplets that vary in size depending on their location in the cloud. PHOTO: BLICKWINKEL/ALAMY STOCK PHOTOClimate models rely on representations of the distribution of cloud water droplet sizes to calculate the radiative effects of those clouds. Assumed droplet-size spectra may not be accurate, however, and could introduce errors into those calculations. Allwayin et al.

    0,0004615 Equipos de investigadores de múltiples disciplinas científicas comienzan a comprender a qué se debe el colapso de la capa de hielo de la Antártida occidental (WAIS, por sus siglas en inglés). Utilizando ADN de pulpo, un equipo de científicos ha descubierto que la capa de hielo de la Antártida Occidental probablemente se derrumbó durante el último periodo interglaciar hace unos 125.000 años, cuando las temperaturas globales eran similares a las actuales.

    Marine Clouds Outlook cloudyH. Jesse SmithNitrate ions made by marine organisms may cause marine aerosol nucleation and enhance cloud formation over the ocean. PHOTO: DAVID BAILEYS/ISTOCK PHOTOOpen in viewerThe possible effects of marine microorganisms on cloudiness above the ocean, and the feedback that such effects might in turn have on climate, have been investigated for years, centering mostly around emissions of dimethyl sulfide. Chamba et al.
