From Wikipedia, the free encyclopedia

I started editing here in the fall of 2006. I was initially very skeptical of the ability of wikipedia to be accurate and useful. However, I have been somewhat convinced and given its high visibility I figured I might as well try to help out where I could since so many people are relying on it for information.

I'm a professional planetary scientist http://www.jaredespley.org/Espley_cv.pdf

[edit] Working copy of Martian Global Warming

Recent evidence shows that the ice at the south pole of Mars decreased in size between consecutive Martian summers [1]. This led to speculation that Mars is experiencing a global increase in temperature similar to the global warming that the Earth is experiencing. However, there is no evidence for such global warming at Mars. In order make such a statement, scientists would need comprehensive temperature measurements across the Martian globe like we have for Earth and would need to more fully understand the numerous long term [2], multi-seasonal [3], and seasonal climate cycles [4] that are still highly uncertain at Mars. Instead what is clear is that Mars is experiencing on-going climate change [5].
