Annual rings are acclaimed in representing natural climate archives. For the temperate latitudes it is known that the growth of these annual rings depend mainly on temperature and precipitation. In ...
In the today's issue of the journal Nature, climate researchers including Jonathan Woodruff of the University of Massachusetts Amherst show that the frequency of intense hurricanes in the Atlantic ...
... in at least 2,000 years. New research in the journal Science provides new evidence that the Arctic would be cooling if not for greenhouse gas emissions that are overpowering natural climate patterns.
... and the results of theoretical climate model simulations suggest an important role for natural drivers of climate such as volcanoes and changes in solar output in explaining the past changes. The ...
The World Meteorological Organisation said Tuesday that 2008 was proving a year of respite from natural climatic phenomena identified by scientists as causing havoc with weather patterns.
