A Dendrochronological Investigation of the Effects of Climate on Latewood Growth in Bohuslän, Sweden
As climate change becomes a more important issue all over the world, information about past climate is of high relevance to better understand what is changing and different from the past. Tree rings can provide information about past climates and has been of value for paleoclimate research and the s...
