We don't know what drives Mars climate or what is supposed to be "normal" climate in Mars. It's an alien world and we just don't know enough of it.
We know enough to note a parallel(with Earth) increase in temperature.
Climate change is a much, much bigger issue than the public, politicians, and even the most alarmed environmentalists realize. Global warming extends to Mars, where the polar ice cap is shrinking, where deep gullies in the landscape are now laid bare, and where the climate is the warmest it has been in decades or centuries.
"One explanation could be that Mars is just coming out of an ice age," NASA scientist William Feldman speculated after the agency's Mars Odyssey completed its first Martian year of data collection. "In some low-latitude areas, the ice has already dissipated." With each passing year more and more evidence arises of the dramatic changes occurring on the only planet on the solar system, apart from Earth, to give up its climate secrets.

The degree of man made influence on GW is debateable. Current alarmism is based
on a premise, & isn't yet conclusive.
More evidence:
Since the late 1970s, the amount of solar radiation the sun emits during times of quiet sunspot activity has increased by nearly .05 percent per decade, according to the study. “This trend is important because, if sustained over many decades, it could cause significant climate change,” said Willson, a researcher affiliated with NASA Goddard Institute for Space Studies and the Earth Institute at Columbia University, and lead author of the study recently published in Geophysical Research Letters.
“Historical records of solar activity indicate that solar radiation has been increasing since the late 19th century,” says Willson. “If a trend comparable the one found in this study persisted during the 20th century it would have provided a significant component of the global warming that the Intergovernmental Panel on Climate Change report claims to have occurred over the last 100 years.”

Who said it could?
