An article from the Uruguay-based English-language Merco Press says:

Patagonia is undergoing the strongest warming process ever in the last four hundred years according to a report jointly elaborated by Argentine and Chilean scientists, and published in the latest edition of the Dutch magazine, Climatic Change.

The report, “Long term climatic changes in the Southern Andes: variations in the XX century in the context of the last 400 years” consists in the reconstruction of temperature patterns in north and south Patagonia since 1640 based on the growth rings of autochthonous trees particularly the Nothofagus Pumilio, locally known as lenga, which grow from northern Neuquén to Tierra del Fuego. ...
