PHOTOS REVEAL CLIMATE CHANGE ON MARS - CAUSED BY CHANGES IN THE AXIS OF ROTATION, NOT MAN-MADE CO2


ESA announced on Thursday that Mars Express has taken images of a crater on Mars which may show evidence that the planet underwent fluctuations in its climate due to changes in its rotation axis.  
ESA’s spacecraft used its high-resolution stereo camera at the Arabia Terra region of Mars on June 19, 2011 to image the Danielson and Kalocsa craters. Danielson crater is filled with layered sediments, and within the crater are peculiarly layered buttes, which are known as yardangs. Yardangs are hills carved from bedrock or any consolidated or semi-consolidated material by abrasive dust and sand particles carried in the wind. These structures are seen on Earth in desert regions, with examples in North Africa, Central Asia and Arizona. 
ESA believes the sediments in Danielson crater were cemented by water, maybe from an ancient reservoir. Scientists theorize that strong north-northeasterly winds both deposited the original sediments and then caused their subsequent erosion in a drier period later on in Martian history. The 18.50 mile-long field of dunes can be seen bisecting the yardangs and is thought to have formed at a later epoch, according to ESA. Danielson’s crater floor shows evidence for a series of alternating sedimentary layers with uniform thickness and separation. 
Some scientists believe this indicates periodic fluctuations in the climate of Mars, which is triggered by regular changes in the planet’s axis of rotation.

SEEMS LIKE CLIMATE CHANGE IS NATURAL TO ALL PLANETS, SO THE ECO-NUTSIES SHOULD STFU AND WE SHOULD END ALL CO2PHOBIC REGULATIONS.
