A study by the Global Warming Policy Foundation (GWPF) finds little evidence purported human-caused climate change is increasing the number or intensity of droughts or heatwaves in the United Kingdom or worldwide.

Citing research in Nature Scientific Data from scientists at the University of California, the GWPF study notes, if anything, there has been a slowly declining trend in drought since 1982. Even the Intergovernmental Panel on Climate Change (IPCC) has found it almost impossible to attribute changes in drought since the mid-twentieth century to anthropogenic warming.
