Belief That Species Evolve Faster In Tropics Debunked
Vancouver, Canada (SPX) Mar 16, 2007
Researchers have discovered that contrary to common belief, species do not evolve faster in warmer climates. UBC Zoology scientists charted the genetic family tree of 618 mammal and bird species in the Americas over the last several million years. By analyzing the DNAs of species that are closely related to one another, the researchers found that speciation - the process in which one species splits into two - takes place faster in temperate zones than in the tropics ... more

    Statistical Analysis Debunks Climate Change Naysayers
    Kamloops, Canada (SPX) Mar 19, 2007
    Despite the fact that the hundreds of scientists and reviewers on the Intergovernmental Panel on Climate Change announced February 2nd in Paris that global warming is "very likely" caused by human activity, governments and other policy-makers may still justify inaction because of naysayers like Danish weather scientist Henrik Svensmark, who maintains that global climate change can be attributed ... more

    Global Temperature Politics Or Science
    Copenhagen, Denmark (SPX) Mar 16, 2007
    The entire debate about global warming is a mirage. The concept of 'global temperature' is thermodynamically as well as mathematically an impossibility, says professor at The Niels Bohr Institute, University of Copenhagen, Bjarne Andresen who has analyzed this hot topic in collaboration with professors Christopher Essex from University of Western Ontario and Ross McKitrick from University of Gue ... more

    Global Sunscreen Has Likely Thinned
    Greenbelt, MD (SPX) Mar 16, 2007
    A new NASA study has found that an important counter-balance to the warming of our planet by greenhouse gases - sunlight blocked by dust, pollution and other aerosol particles - appears to have lost ground. The thinning of Earth's "sunscreen" of aerosols since the early 1990s could have given an extra push to the rise in global surface temperatures. The finding, published today in the journal Sc ... more
