The planet Mars is undergoing significant global warming which supports many climatologists’ claims that the Earth’s modest warming during the past century is due to a recent upsurge in solar energy, says James M. Taylor, of the Heartland Institute.
For three Mars summers, deposits of frozen carbon dioxide near the planet’s south pole have shrunk from the previous year’s size, suggesting a climate change in progress, says Taylor. Furthermore, documented changes from 1999 to 2005 show that Mars’ climate is presently warmer, and perhaps getting warmer still, than it was several decades or centuries ago.
But there are not a lot of anthropogenic gas emissions on Mars, so what internal dynamic is warming the planet and what does it mean for Earth? According to researchers:
Furthermore, the warming of Mars adds another level of uncertainty to claims that the Earth’s modest recent warming is a result of human activity, says Taylor.
