The light, bright, oxidized martian surface soil reflects a significant amount of solar radiation, tending to keep Mars cool, just as wearing white on a hot summer’s day is cooling. The darker, more absorbent subsurface soil, revealed after a windstorm or dust devil passes through on Mars, retains more heat, just as wearing dark clothes will on that same hot summer’s day here on earth. The result of more exposed dark soil is that the temperature of Mars has gone up between one and two degrees over the last two decades. </SPAN></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/F292DE70-CD9E-4F7F-85A1-B0AB118244C3/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
