Brazil in LIA

At https://phys.org/print451717673.html … isotopic records obtained from caves show how rainfall distribution in Brazil was affected by the Little Ice Age (Geophysical Research Letters, July 2018). They are defining the LIA as AD1500-1850 when average temperatures were lower than at present. In the 17th and 18th centuries climate in parts of Brazil was much wetter – but in the NE is was much drier. The same speleotherm data showed climate in Brazil was drier between AD900 and 1100, the so called Medieval Warm Period, and all this seems to reflect shifts in the equatorial rain belt.
