Cambridge, MA- Adding particles to liquids to make currents visible is a common practice in the study of fluid mechanics. The approach was adopted and perfected by artist Paul Matisse in sculptures he calls Kalliroscopes. Matisse’s glass-enclosed …
An International research team has discovered that seasonal temperatures in Europe, above all in winter, have been affected over the past 500 years by natural factors such as volcanic eruptions and solar activity, and by human activities such …
CORVALLIS, Ore. — A new analysis of the Northern Hemisphere’s “albedo feedback” over a 30-year period concludes that the region’s loss of reflectivity due to snow and sea ice decline is more than double what state-of-the-art climate models esti…
Scientists studying a column of Antarctic ice spanning 650 years have found evidence for fluctuations in biomass burning–the consumption of wood, peat and other materials in wildfires, cooking fires and communal fires–in the Southern Hemisph…
Clouds play a major role in the climate-change equation, but they are the least-understood variable in the sky, observes a Texas A&M University geoscientist, who says mid-level clouds are especially understudied. The professor, Shaima Nasiri, is mak…
ESA GlobSnow project led by the Finnish Meteorological Institute uses satellites to produce up-to-date information on global snow cover. The new database gives fresh information on the snow situation right after a snowfall. Gathering this informatio…
Just as vegetables are essential to balancing the human diet, the inclusion of vegetation may be equally essential to balancing Earth’s climate models. Scientists at MIT who were trying to create accurate models of climate change in the southern portion of the Sahara desert found that including a realistic component of vegetation growth and decay was absolutely essential. Without including the vegetation as a variable (rather than a fixed parameter), the models were not able to show the region’s transformation from a fertile expanse of vegetation 6,000 years ago to an arid stretch of mostly sand and mountains today.
