Climate prediction is difficult stuff.   As you know, it's impossible to predict the weather 10 days from now much less six months and aside from "it will get a lot worse" no one can say with any degree of certainty what Earth's climate could look like in the future given changing kinds of pollution conditions and nature itself.

Introducing presumed consent or opt-out system may increase organ donation rates, suggests a new systematic review published in the BMJ (British Medical Journal).

There is currently insufficient supply of donor organs to meet the demand for organ transplantations in the UK but the number of patients registered for a transplant continues to increase. In March 2008, 7,655 patients were on the active transplant list and 506 died in the years 2007-2008 while waiting for their transplant.

At present the UK has an informed consent legislative system where individuals opt-in if they are willing for their organs to be used after death. However, only a quarter of the UK population are on the NHS donor register. 

With record low temperatures, winter blizzards and warming that isn't really global, people aren't taking climate change very seriously these days, but that doesn't mean pollution gets a free pass if we want to continue to enjoy nature as we know it.   Temperature change in the Arctic can still happen regardless of what is happening in cold spots of the world and  it may be happening at a greater rate there than other places in the Northern Hemisphere.

As a result, glacier and ice-sheet melting, sea-ice retreat, coastal erosion and sea level rise could continue even if it doesn't feel warmer in Chicago.

That's how many mated pairs will need to have survived the extensive habitat loss that occurred during the early 1900's for the ivory-billed woodpecker to still be around today.

Do they exist?   No one knows, though in the last few years people have claimed to see them.   But people have claimed to see Bigfoot too.

Take heart, parents.   If your teenager is brandishing a virtual shotgun in their new video game, you're not raising the next Columbine kid.    If they're enjoying themselves, it's because of the healthy pleasure of mastering a challenge rather than from a disturbing craving for carnage. 

A new Commonwealth Fund study says that the United States should adopt the policies of Switzerland and the Netherlands.    Those countries have near-universal coverage, though they have to subsidize up to 40 percent of families since individual health coverage is mandated by law.

The result?  Both countries effectively cover all but one percent of their population, compared with 15 percent uninsured in the U.S.
