Extinction linked to global warming
Scientists have long suspected that global warming might cause extinctions. But until a group from the University of Leeds produced an influential model in 2004, 1 "nobody had managed to frame the question," says Chris Thomas, the paper's lead author, now at the University of York. Thomas' group modeled relationships between distributions of 1,103 animal and plant species and their habitats across 20% of Earth's terrain using three climate-warming scenarios. Based on the midrange scenario, with temperature increases of 1.8-2.ᄚC, they concluded that 15-37% of species will be committed to extinction by 2050. "Some of them will be extinct by then. The majority of them will be in decline," Thomas explains. This was "the first time that a group had taken such a large-scale collaborative approach to this problem," says Timothy Baker at Leeds. The paper convinced scientists and policy makers alike to consider climate changes as destructive as human land use. Since then, researchers around the world have turned their attention towards individual species at risk from the changes. A recent study blames the extinction of two-thirds of the 110 harlequin frog species in tropical America on global warming. 2 Based on this, Thomas says, "We are more than on course, unfortunately, to lose the percentage of species that we've projected." 1.

Independent report on global heating on a commission basis defies of experts to deny a hypothesis. by Rafael Lomeᅢᄆa Varo [Comment posted 2007-03-15 15:57:01] [Translation made by automated means in Google]
[To Him request excuses to possible errors] The only thing that we know is that nobody knows for sure towards where the climate goes, but please, we do not commit a folly. It is necessary to be blind not to see the harmful interference of the man in the global warming, for that reason, we continue investigating and working to improve, although he is little, perhaps insufficient. But sometimes I think that saddest of all this, it is that after many months investigating by my account the phenomenon from a new perspective, nobody could imagine that the difficult thing would not be to discover a possible "agent direct cause" of the complex phenomena of the climatic change and the ACCELERATED global heating, but be able the most mini mediatic cover to accede, at least, to a revision of my hypothesis on the part of a commission of several experts. The one of the heating already seems a question difficult to justify, for example, in Spain, the brown bear no longer hiberna. The one of the antropogᅢᄅnico factor seems that also it begins to signal of "consensus" in accordance with little published on 4ᅡᄎ report that the IPCC will make public at the end of this year (2007). Nevertheless, it is paradoxical which certain variables directly involved like are the excess of forest fires on global scale (according to the few estimations to that I could have had access, between 30 and 55 million hectares of forest (30 mill. hectᅢᄀ. = 300 thousands Km2 = complete surface Italy) they are losing every year in the occasion of forest fires), follow forgotten in darkroom the trastero of the investigations. If they want to see the consequences of these facts and some simple calculations on the matter, can be documented in my personal Web: + LINK Also I inform to them that I have been months trying that some means publish the information, but is impossible. Good, in case to some it interests to him, this is my news, in primicia, to which the means insist on ignoring. TO TITLE: Independent report on global heating on a commission basis defies of experts to deny a hypothesis. A recent independent report on climatic change and global heating elaborated by a nontie investigator absolutely with no corporative nor governmental being, tries to warn the scientific group that the measures adapted in this sense when ignoring itself are not being taken factors that can be determining on the phenomenon. The report specially points at the excess of forest fires like direct coagent cause of the effect conservatory and its possible impact in the increase of extreme meteorological phenomena at global level. Although the author of this report is not excluding with any of the present lines of investigation as well as the policies of reduction of antropogᅢᄅnicas gas emissions conservatories, the same one alleges with rotundidad the alarming indifference that apparently are being granted to the factor of the forest fires and the possible repercussions that these can be already affecting in the phenomenon of the climatic change, in addition to the urgent necessity of cocienciaciᅢᄈn on the matter on the part of all the social agents, fundamentally average of diffusion and governmental beings. Also, the document analyzes the real possibilities to fight the phenomenon of the global heating through the control, prevention and partial eradication of forest fires on global scale. The access to the complete report as well as other documents and calculations of interest for the reader can be in: + LINK (Report - spanish) + LINK (simulator and other book calculations for Microsoft Excel - spanish) "... NOTE: It would be thankful to them that they did not publish the complete report, but the news that them envio, since in such case would have to authorize to them specifically in writing. Rafael Lomeᅢᄆa (Spain) Globalwarming Awareness2007 by Brad [Comment posted 2007-01-24 18:08:04] Taking the appropriate measures today will help to move us away from the models predictions. We must find a new, clean source of energy within the next couple of years to help with this.
