...Science (ICESS). Phytoplankton grow faster in a cool ocean and slower in a warm one, said Siegel. The scary part is that the oceans are warming now probably caused by our emissions of greenhouse gases like carbon dioxide. These microscopic plants are predicted to grow even slower in the warmer ocea...Global warming will reduce ocean productivity, marine life
...th the end of the El Nino, global climate began to cool and there was a surge in ocean phytoplankton productivity that peaked in late 1999. The second climate event was a long-term warming trend that started in 2000 and continues today. Over this period, the ocean sea surface became overall warmer and...The Milky Way shaped life on Earth
...ivity coincided with high star formation rates and cool periods in Earth's climate. Conversely, during a billion years when star formation was slow, cosmic rays were less intense and Earth's climate was warmer, the biosphere was almost unchanging in its productivity. This reveals a link more subtle tha...Climate changes are linked between Greenland and the Antarctic

This result suggests a general link between long-term climate changes in both hemispheres via this Bipolar Seesaw as a result of Atlantic Meridional O......r Treatments for Lice Were Studied "The cool thing about the machine is, it works unlike many other treatments that haven't been rigorously tested," Clayton says.

During the PETM, temperature differences from the tropics to the poles were lower, reducing rainfall between the subtropics and the North Pole and increasing the amount of water transported to the Arctic, said Pagani.

Attempts to cool the brain to reduce injury from stroke and other head trauma may face a significant obstacle: current cooling devices can't penetrate very deeply into the brain.
