He has been studying the effects of climate change and land-use on the Lamprey. Analysis of local weather history has shown that the number of extreme weather events has been increasing in the last 60 years. More rain falls more quickly, overwhelming the land’s ability to absorb water. The amount of rainfall in a severe storm has been up to four times the amount that once fell. Less snow is falling in winter, and, instead, more rain has been falling. What snow does accumulate melts earlier in the spring. The Lamprey, as a result, has experienced three severe floods in the past ten years, floods that historically have occurred only once in about a hundred years. These floods have damaged buildings and public infrastructure, such as roads and bridges.
