Research Spotlight: Soil temperature trends in Canada



[1] Global warming increasingly is becoming a concern for society. Most reported warming trends are based on measured increases in air temperatures. However, trends in soil temperatures, also an important indicator of climate change, are less often reported.Qian et al. analyzed soil temperature data from 30 climate stations across Canada covering the period from 1958 to 2008; the data cover soil temperatures at several depths up to 150 centimeters. They also analyzed air temperature, precipitation, and snow cover depth at the same locations. (Journal of Geophysical Research-Atmospheres, doi:10.1029/2010JD015012, 2011)
