As La Nina slowly comes on, the prospects of a droughty and hot summer are increasing. Historically this has especially been the case after El Nino winters. Drought and heat would of course be blamed on global warming but the historical plots of drought show there is no tendency for a steadily increased frequency of drought during the last century.
