Polar bears could start attacking humans more frequently due to global warming, a Russian scientist said Friday.
Polar bears are carnivores that mainly live on seals, but can also feed on birds, shellfish, rodents and walruses - anything they can catch and kill. They are more likely to hunt humans than other bears and attacks could, for instance, happen at hunting camps or weather stations.
"Sea ice [the area covered by ice in the Arctic] is decreasing, and this is the polar bear's main habitat... In a search for food, the bears could end up at coastal areas and approach villages on the sea shore," Oleg Anisimov, a professor at the State Hydrology Institute under Russia's hydrometeorology service, told a news conference.
Earth Changes
Researchers are forecasting a one-in-three chance that the extent of sea ice covering the Arctic will reach an all-time record low this year.

Keep that in mind these days, where 'global warming' is IN and the political consensus has already made it's mind up.

Australia has warned that it will have to switch off the water supply to the continent's food bowl unless heavy rains break an epic drought - heralding what could be the first climate change-driven disaster to strike a developed nation.
The Murray-Darling basin in south-eastern Australia yields 40 per cent of the country's agricultural produce. But the two rivers that feed the region are so pitifully low that there will soon be only enough water for drinking supplies. Australia is in the grip of its worst drought on record, the victim of changing weather patterns attributed to global warming and a government that is only just starting to wake up to the severity of the position.

At least four earthquakes with a magnitude of about 6.0 on the Richter scale shook the East China Sea early Friday.
High temperatures can reverse the sex of dragon lizards before they hatch, turning males into females.
The finding, detailed in the April 20 issue of the journal Science, could have implications for the development of life as the planet's climate warms.
The research reveals that extreme temperatures could inactivate a gene on the male sex chromosomes of dragon lizards and thus turn male embryos into females. The sex-reversed lizards look female and have female organs but genetically they are male, said lead author Alexander Quinn of the University of Canberra in Australia.

When conservation officer Steve Peterson got a call that a timber wolf was chasing vehicles on a country road near Brimson, he thought it was prank or a misidentified German shepherd. But then he saw it firsthand.
"I couldn't believe it. It was like a dog chasing cars,'' Peterson said. "It looked like a big, healthy male wolf. No mange.''
Responding to the call last Friday, Peterson saw the animal hide in the ditch as a pickup approached and then come bounding out to chase it.
The wolf did the same when Peterson drove to that spot, where he stopped his vehicle.

NEIVA, Colombia - Thousands of people were evacuated after a long-dormant volcano erupted late Tuesday and again early Wednesday, provoking avalanches and floods that swept away houses and bridges.
The storm that walloped the Northeast on Monday, April 16, was the culmination of a five-day weather event and left behind significant conditions.
