(NOAA Headquarters) NOAA scientists plumbed the deep ocean, probed the heights of the stratosphere, and surveyed some of the fiercest storm systems on Earth in meeting 2011′s scientific challenges. Their discoveries are paying off in longer storm warning lead times, better understanding of our climate, and new knowledge about environmental disasters.

(University of Colorado at Boulder) Two University of Colorado Boulder researchers who have adapted a three-dimensional, general circulation model of Earth’s climate to a time some 2.8 billion years ago when the sun was significantly fainter than present think the planet may have been more prone to catastrophic glaciation than previously believed.

(University of California – Davis) The impact of deforestation on global warming varies with latitude, according to new research from a team of scientists representing 20 institutions from around the world. The finding, which researchers say calls for new climate-monitoring strategies, will be published in the Nov. 17 issue of the journal Nature.

(Yale University) Deforestation, considered by scientists to contribute significantly to global warming, has been shown by a Yale-led team to actually cool the local climate in northern latitudes, according to a paper published today in Nature.

(Woods Hole Oceanographic Institution) Woods Hole Oceanographic Institution (WHOI) scientists have discovered that bacterial communication could have a significant impact on the planet’s climate.

(Helmholtz Association of German Research Centres) Earth warming will presumably not lead to a permanent El Nino state in the South Pacific Ocean. This is the conclusion drawn by an international team of researchers after it investigated 50-million-year-old clam shells and wood from the Antarctic. The growth rings of these fossils indicate that there was also a climate rhythm over the South Pacific during the last prolonged interglacial phase of the Earth’s history resembling the present-day interplay of El Nino and La Nina.
