Observations and climate reconstructions using data from tree rings confirm that human activity was affecting the worldwide drought risk as far back as the early 20th century.

New research from the NASA Goddard Institute for Space Studies (GISS), Lawrence Livermore National Laboratory (LLNL) and Columbia University shows that greenhouse gas emissions in the first half of the century (1900-1949) significantly affected temperature and rainfall and caused large hydrological shifts over land. The research appears in the May 1 edition of the journal Nature.
