Retraction?
I don't think it's anyone else's job but mine to retract. And I don't feel much like retracting anyway. We still see Mars as a cold arid world, most of the time and most places. The "water" hat has been found is mostly ice or evidence of strongly acid waters that could still flow at present-day temperatures.
The case for CO2 flows is still valid, although they may be less likely given new evidence. In particular, the near-polar gullies are still evidence for CO2 phase change being involved in gas-supported flows in these and perhaps all gullies.
When I get some spare ime, I'll rework the White Mars website...
