Volcanoes have incredible effects on the weather; eruptions create localized weather phenomena like acid rain and violent volcanic lightning.
Scientists are just now unlocking the amazing secrets of how rain is made; some raindrops form around micrometeorites from outer space, others are created by bacteria that float into the upper atmosphere.

Science in Antarctica will shut down for the winter. Scott Base has plenty of logistics to manage in order to send teams out to finish their missions for the season. The USS Coast Guard crew is challenged by their aging ship as they try to finish cutting a channel in the ice before they escort the ship in. The Mt. Erebus team struggles to salvage as much data as they can before they go home.

The air around us is not just empty space; it is an integral part of the chemistry of life. Plants are made from carbon dioxide, nitrogen nourishes the soil and oxygen gives us the energy we need to keep our hearts pumping and our brains alive. But how did we come to understand what air is made of? How did we come to know that this invisible stuff around us contains anything at all?
From space, Earth is a kaleidoscope. Turquoise plankton blooms trigger a feeding frenzy, China turns yellow with rapeseed flowers, and mysterious green lights appear in the ocean.
