Birds face longer migration due to climate change, experts warn
Journey could increase by 250 miles, posing serious threat to many species
Migrating birds such as the garden warbler and whitethroat will face longer journeys because of climate change, experts warned today.
A team of scientists led by Durham University has demonstrated that while the birds’ breeding ranges are likely to shift northwards, their wintering areas will not, thus increasing the length of their journeys by up to 250 miles. The study, published in the Journal of Biogeography, has serious implications for many of the birds returning this month to Britain to breed.
The research team used computer simulation models similar to those used by weather forecasters to analyse how climate change might affect the migration patterns of European Sylvia warblers.
Every year these tiny birds – some weighing as little as 12g – travel thousands of miles northwards from their African winter-quarters to breed in Europe and Asia. Up to 500 million birds undertake this epic journey to take advantage of the long summer days and glut of insect food in temperate latitudes.

Who will you vote for this year: Big Oil, Big Casinos, or Wall Street?
Billionaire hedge fund manager - and primary contributor to Rick Santorum's Red, White, and Blue SuperPAC - Foster Friess let the truth slip out about politics in this post-Citizens United age during an interview with Politico. Friess was among several billionaires who attended the Koch brothers secret meeting last month where over a hundred million dollars was pledged to beat President Obama.Trying to get other oligarchs on the side of Rick Santorum - Friess said, "There isn't a person at the Koch brothers events who would not get a good return on their investment by investing in [Santorum] as president, because of what they believe about the free enterprise system." The key word there: investment. These aren't campaign contributions - these are investments that millionaires and billionaires are making to keep their tax breaks, their subsidies, and their lax regulations in place.We no longer have actual people running for President - we have a few very, very rich people like Friess and the Kochs investing in stooges to do their bidding - and hoping to see major returns in their bank accounts. So who will you vote for this year? Big Oil, Big Casinos, or Wall Street?-Thom(Who will you vote for this year? Tell us here.) -

The modern conservative is engaged in one of man's oldest exercises in moral philosophy; that is, the search for a superior moral justification for selfishness.
