One sign that the world is warming up is when insects that normally live in the south start arriving in areas with colder climates. This is happening already in the U.K., where the stink bug?familiar in the American South?is now living. “I’m always reluctant to invoke global warming but it’s the only explanation,” says Max Barclay, curator of beetles at the Natural History Museum.

These insects regularly arrive in the U.K. along with loads of fruits and vegetables, but this is the first time they’ve decided to stay and breed, because it’s always been too cold for them before. Besides the U.S., it was once found only in the Mediterranean, the Middle East, Australia and Africa.

Cars powered by hydrogen fuel cells look like they could bring us clear skies tomorrow, because we’d no longer have to worry about either CO2 emissions or an oil shortage.

But if we start with oil, how will that change things?

Crop circles aren’t new and people have been seeing them made (and not by other people, either) for over 50 years. Alec Randall of Wiltshire, England describes looking into a field with his girlfriend in 1955 and seeing a “distortion of the air, like a thick haze of heat” 20 feet above a wheat field. They heard a “cracking noise like an electric shock noise?an electrical bang.” When the haze lifted 20 minutes later, there was a circle in the field.

Nick Redfern writes that the resulting shape was a perfect circle about 8 feet in diameter. The wheat was flattened in a “beautiful swirl but with a smell of burning metal in the air which lasted for a few minutes or until we got used to it.”

In the Yukon village of Teslin, Bigfoot has been seen at a construction site near the airport. Conservation Officer Dave Bakica says the two people who saw it “claim they thought it was a person standing beside the road, but couldn’t tell from all the dust. By the time they turned around to look back they said this person was completely covered in hair and took just two strides to get across the whole Alaska highway.” And one Bigfoot researcher is determined to bring back photographs of a Yeti from Sumatra.
