Love or hate Obama, but to do this to ANYONE is inhuman.
The Atlanta Braves have been deluged with hate mail after baseball great Hank Aaron's recent comments about racism in America and President Obama's critics.

Including blockade running and wampa slicing as events.
 
If Bioware sponsored the Winter Olympics, it would probably look something like this

Do not come to my house with the following statements

- I'm just doing my job.
- I've got 20 years in with the department, I'm afraid to lose my pension.
- Please, don't make me break the door in.

Et al.

White Mars

This is Mars as it might have appeared during the height of its last ice age! 

Of all planets in the Solar System, Mars has the climate most like ours.   Both Mars and Earth are sensitive to small changes in the shape of its orbit and the tilt of its axis. 

On Earth, when the axis tilts more, the poles warm up and ice ages end.  But a 2003 paper in Nature did simulations and found that Mars works the other way!  When its axis tilts more, the poles warm up, and the polar ice caps start to evaporate... bringing more water to the whole planet.  But since Mars is below freezing most of the time, that brings ice all the way down to 30° latitude in both hemispheres, as shown here.

From about 2.1 million to 400,000 years ago, the increased tilt of Mars' axis made its poles warmer.   But the tilt has been less since then.  This is making the poles colder, so water vapor has been leaving the zone between 30° and 60° latitude, and collecting in the ice caps. 

If you haven't read Kim Stanley Robinson's trilogy Red Mars, Green Mars, Blue Mars, you really should.  It's a sprawling tale of the terraforming of Mars, packed with fascinating digressions.  Now I want White Mars.

It was prepared for the December 18, 2003, cover of the journal Nature.   The simulated surface deposit is superposed on a  map based on altitude measurements by Global Surveyor and images from NASA's Viking orbiters of the 1970s.

The paper is here:
