  1. (A) Statement I: Higher temperatures give rise to a more active water cycle,
    which means more evaporation and precipitation as well as more extreme
    weather events.
    Statement II: Some of the fastest-warming regions on the planet include
    Alaska, Greenland, and Siberia. These Arctic environments are highly
    sensitive to even small temperature increases, which can melt sea ice, ice
    sheets, and permafrost. This can also lead to changes in Earth’s reflectance
    (“albedo”).
    Statement III: Air pollution can take the form of fine particles called
    “aerosols,” which both absorb and scatter the sun’s radiation. Both natural
    and man-made aerosols, such as dust, sea salt, soot, and sulfates, affect the
    climate by reflecting radiation that is transmitted through the atmosphere.
