The Worst Part of Climate Change
David Biello of Scientific American on climate change possibly lengthening the day:
In the extremely distant future, such lunar tidal friction will actually slow the Earth’s spin until a day is as long as a month (though the sun might swallow up the Earth-moon system before that ever happens). In the shorter term, warming the world’s oceans might actually make the day go by a little quicker.
This is where it gets very, very bad; from the Daily Mail in the U.K.
Human beings probably developed in Africa between one and two million years ago, but red never only appeared once they had settled in the cooler climates of Europe, possibly as recently as 20,000 years ago.
Red hair is considered genetically less advantageous because ‘gingers’ commonly have fair skin, which makes them more susceptible to sunburn and skin cancer.
In scorching Africa, that would have seen the ginger strain die out in large populations.
But when small tribes began to move north through Europe, where summer days are cooler and winters longer, the small gene pools ensured redheads became more common, and were able to survive in the more hospitable environment.
Redheads are our most precious commodity, apart from chubby babies. This can not become reality.
