Arctic Plants at Risk
Genetic variations within species will determine which plants fare well in warming Arctic habitats and which may struggle.
Species that are able to disperse their seeds via birds or the wind are less likely to lose their genetic diversity when their habitats are altered by climate change, according to a study by the University Centre in Svalbard, Norway. Trees and taller shrubs will likely fare better than species that have little opportunity for gene flow between populations.
The study may affect how species are identified for protections, since loss of habitat may not necessarily threaten a particular species, the researchers conclude.

Why the Future Will Almost Certainly Be Better than the Present
Five hundred years ago there was no telephone. No telegraph, for that matter. There was only a postal system that took weeks to deliver a letter. Communication was only possible in any fluent manner between people living in the same neighborhood. And neighborhoods were smaller, too. There were no cars allowing us to travel great distances in the blink of an eye. So the world was a bunch of disjointed groups of individuals who evolved pretty much oblivious to what happened around them.

Where is the Future?
Like the road you can see ahead of you as you drive on a journey, I suggest the future is embedded in emerging, continuous space-time. Although you’re not there yet, you can see the road in front of you. In the rear-view mirror stretches the landscape of the past, the world you have been through and still remember.
Transparency 2013: Good and bad news about banking, guns, freedom and all that
“Bank secrecy is essentially eroding before our eyes,” says a recent NPR article. ”I think the combination of the fear factor that has kicked in for not only Americans with money offshore, countries that don’t want to be on the wrong side of this issue and the legislative weight of FATCA means that within three to five years it will be exceptionally difficult for any American to hide money in any financial institution.”
