general slowly warming, but that the mean martian surface temperatures are not expected to increase by more than 0.2 K over the next 500 years. Finding 2-1: Modern Mars environments may contain molecular fuels Revised Finding 2-1: Modern Mars environments and oxidants that are known to support metabolism and cell division of may contain chemical compounds that are used chemolithoautotrophic microbes on Earth.

However, there are suggestions aw unknown, and perhaps variable. As such they meet the criteria that they are due to the seepage of liquid water for Uncertain Regions, to be treated as Special Regions.

Although some recent results have strengthened that conclusion for non-RSL slope streaks, other recent reports suggest that there are problems explaining all dark slope streaks by dry granular flow, and therefore aqueous processes cannot be definitely excluded for all dark slope streaks. Finding 4-9: Polar dark dune streaks are considered extremely unlikely Revised Finding 4-9: A conservative interpretation to involve liquid water warmer than 253 K (–20°C)
