Does the Mars melt relate to what is happening on Earth??

One scientist is going against the grain by claiming that global warming on Earth may be solar, and not human related. Does this mean man is really the cause of global warming here on Earth, or is the cooling and warming of naturally occurring because the wobble in a planets orbit around the sun?

The conventional theory is that climate changes on Mars can be explained primarily by small alterations in the planet's orbit and tilt, not by changes in the sun.
"Wobbles in the orbit of Mars are the main cause of its climate change in the current era," Oxford's Wilson explained. (Related: "Don't Blame Sun for Global Warming, Study Says" [September 13, 2006].)
All planets experience a few wobbles as they make their journey around the sun. Earth's wobbles are known as Milankovitch cycles and occur on time scales of between 20,000 and 100,000 years.
These fluctuations change the tilt of Earth's axis and its distance from the sun and are thought to be responsible for the waxing and waning of ice ages on Earth.

Is Dr.Abdussamato's theory valid, or does the fact that Dr.Abdussamato's omit greenhouse gas emissions as causes for global warming invalidate his theory??
