Water that drips from aboveground into caves to form stalactites and stalagmites carries with it paleoclimate signatures in isotopic ratios. Now, researchers say this geochemical record may be altered by fires, which could add complexity to paleoclimate interpretations (Hydrol. Earth Syst. Sci. 2016, DOI: 10.5194/hess-20-2745-2016). From 2005 to 2011, a team led by Andy Baker, Gurinder Nagra, and Pauline C. Treble of . . .
