    Flying into the cold unknown

    Typically, pilots avoid flying where icing conditions can occur, but researchers are flying into extremely cold weather in order to study an Arctic phenomenon known as marine cold air outbreaks (CAOs). CAOs and the clouds they generate may have far-reaching climate impacts and scientists are hoping to understand more about the role they are playing in the rapid warming of the Arctic.

    Northern tropical Africa not the significant carbon source satellite data suggests

    The forests and grasslands of northern tropical Africa take in about as much carbon dioxide in the wet season as they release in the dry season, according to a new study based on observations from aircraft. The findings contradict earlier research that relied on satellite data and found that these ecosystems may be adding significantly more carbon to the atmosphere than they absorb over the course of a year.
