A comprehensive new study in the Journal of Hydrology finds the Intergovernmental Panel on Climate Change is likely wrong by a factor of 10 or more in its claim precipitation increased in some regions by as much as 1 percent in each decade of the twentieth century. Using more than 1.5 million monthly precipitation totals from 1,000 measuring stations in 114 countries, the researchers determined there has been “No significant global precipitation change from 1850 to present.” While data for some stations extend back to the 1700s, most of the data come from stations that have existed since 1850, with all stations providing data for more than 100 years.
The researchers plotted the percentage of annual precipitation change relative to the years 1961 to 1990 for six continents, as well as for stations at different latitudes and those experiencing low, moderate, and high annual precipitation totals. They found no substantial differences for stations located in northern, tropical, or southern latitudes. From 1850 to 2000 the percentage rate of precipitation change was –1.2 ± 1.7 per century, or less than 0.09 mm per decade – far less than the 1 percent per decade change claimed by IPCC.
