Take a look at the sequence of images below (I recommend clicking through to enlarge, Tumblr Dashboard folks). Works best if you stare at the dot:
Color? Or black and white?
The rods and cones of your retina respond to the illumination (black-white) and color of a scene, respectively….

Ice Caves Around the World
Ice caves come in two forms. A cave formed entirely of ice is actually called a glacier cave and as the name implies, forms in glaciers. Water runs through or under the glacier and forms a cave.
The other type of ice cave can be any cave type (limestone, lava tube, etc.) that has ice in it year round. These caves trap cold air. Water entering the cave freezes and stays frozen year round.
Glacier caves can be found in the Pacific Northwest and ice caves are found in many locations where temperatures drop below freezing. Once cold air enters the cave, it generally stays there.

Climate Change Models Prove Accurate
In a recent paper published in Nature Geoscience, scientists compared global temperatures of the last 15 years to that of a model that was developed in 1996. The results show that climate change and global warming predicted were accurately predicted to within a few hundredths of a degree. The good news is that these models are a useful tool, the bad news is that the feared change occurred.
