On May 4, 1700 the town of Salamanca made prayers to the Virgen de la Vega for rain. This fact, apparently just reached the category of historical anecdote may be part of a line almost unexplored climate research: the historical record. Miguel Angel Fuertes, scientist in the Department of Geology at the University of Salamanca, has followed this trail in the records of capiturales chapter of the Cathedral of Salamanca, a faithful witness of all types of incidents, including weather.
 “The idea is to obtain paleoclimatic data from different sources,” says Miguel Angel Fuertes. “Recent data from high resolution,” ie less spaced in time that they can provide other data, such as looking at marine sediments his new roommate.
To do this, ideally you have data of temperature or atmospheric pressure taken with instruments, but are only reliable from the mid eighteenth century, so “if we try to study long-term changes in climate, we need information that goes beyond” explains the expert.

After impact the asteroid that hit the earth’s surface 65 million years ago, nearly 80% of marine life became extinct and the climate cooled dramatically. An international team of researchers in Science now reveals that the ocean, marine productivity or photosynthesis recovered in less than a century.
The new geochemical study by researchers at the University of Bremen (Germany), the Massachusetts Institute of Technology (MIT, its acronym in English), and the University of Jena (Germany) shows that photosynthesis, the basis of the marine food web, was only interrupted for 100 years, so that his recovery was “surprisingly” fast.
“The oceans were able to recover quickly after the environmental disaster associated with impact of the meteorite, and apparently could reorganize ecosystems very rapidly,

New research that reconstructs the extent of ice cover since the thirteenth century to the present day in the sea area located between Greenland and Svalbard, Norwegian archipelago in the Arctic Ocean, said that during that time there has never been so little ice now.
