Mars Is Coming Out Of An Ice Age (reuters.com)

Taco Cowboy quotes a report from Reuters: An analysis of radar images that peered inside the polar ice caps of Mars shows that Earth's neighbor is coming out of an ice age that is part of an ongoing cycle of climate change, scientists said on Thursday. Using images taken by satellites orbiting Mars, the researchers determined that about 20,872 cubic miles (87,000 cubic km) of ice has accumulated at its poles since the end of the ice age, mostly in the northern polar cap. Scientists are keenly interested in piecing together the climate history of Mars, which contains strong evidence that oceans and lakes once pooled on its surface, bolstering the prospects for life. From the perspective of an Earthling, every day on Mars may feel like an ice age. According to NASA, temperatures on Mars may hit a high at noon at the equator in the summer of roughly 70 degrees Fahrenheit (20 degrees Celsius), or a low of about minus-225 degrees Fahrenheit (minus-153 degrees Celsius) at the poles. The Martian ice began its retreat about 370,000 years ago, marking the end of the last ice age, according to the research published in the journal Science

Except in Earth's case, Earthlings and their civilization are somehow to blame for the temperature rising and not the natural cycles the planet has gone through in the past, long before humans were a gleam in Darwin's eye.

TFA:

The climate cycles are triggered by changes in Mars' orbit and tilt, which affect how much sunlight reaches the planet's surface.

The shifts are particularly dramatic on Mars because theplanet's tilt changes by as much as 60 degrees, compared to variations in Earth's tilt of about 2 degrees.

Since we've already accounted for the effect of Earth's orbit and tilt (which run on 100,000 and 20,000 year cycles), unless you have a bitchin' theory for how Mars' orbit and tilt afffect the climate of the Earth, we're still pretty damn confident that it's the humans.
