It is a point of view at least original. A Danish researcher explains that it is necessary to keep reservations of hydrocarbons to struggle against next glacial age.
In Geophysical research letters of February 11th, 2009, Gary Shaffer, the University of Copenhagen, itemises his calculations and envisages that a climatic warming of five degrees in one
Know past to include the gift better and to imagine the future. An international team offers to study the ancient climates from size and from corpulence of the snakes. By studying giant's fossil (13 metres long for a ton) dating about 59 million years, she draws a new vision of climate [...]
It has the air of nothing, but there is a deposit of natural gas which does not reject carbon dioxide, or almost. The systems of illegal securement of the methane of In Salah (Algeria) separate gases and re-inject CO2 in basement. Every year, these would be not less than eight hundred thousand tons of this gas [...]
While the European Union had to soften its "packet-climate" to satisfy all States, the techniques of géo-engineering of climate appear more and more as an appeal to struggle against climatic warming. But in Australia, a report of the co-operative Research centre on Antarctic climate and ecosystem (ACE-CRC) casts doubt on [...]
Can the thirst for black gold be made at any price? The extraction of the colossal reservations of bitumeux sands in the north of Alberta (Canada) makes the object of deep protests on behalf of scientists and of environmentalists. Last there dates, a report of the American Council of defence of natural resources (NRDC) gets worried about threat of [...]
Reality sometimes takes amazing positions. While they often recall the programmes of methane caused by the thaw of the boreal soil, researchers show that the Nordic marshes also liberate some gas when they freeze, in autumn.
The humid lands of high degrees of latitude are an important source of programme of methane in the atmosphere. A consequence of [...]
They begin knowing about it a little more about the evolution of the polar floe this summer in the big North. The American Centre of data on the snow and the ice (NSIDC) published on Wednesday its first analyses. The surface of ice of Arctic sea got closer to the historical minimum of last year, without [...]
It is sometimes good to search databases. While going about things as well an international team calls into question an idée reçue on the ancient forests. While they thought that they cease sequestrating some carbon, playing neutrality in exchanges of carbon dioxide with the atmosphere, the ancient forests of temperate zones [...]
He is even too early to be sure there, but year 2008 could be the most cold of this century. It is what estimate the climatologists of the British weather forecast, contacted by BBC, on the evidence of measures performed since the beginning by the year.
More cold of the century? Yes, but of the XXIth Coach if conditions of [...]
What's happening above our heads when soots produced by the combustion of the coal and of the oil get old in the atmosphere? A suèdo-American team brings the beginning of answer, in the Annals of the American Academy of sciences (1). By getting old, soots suffer chemical and geometric transformations which reinforce their capacity in [...]
