A database created by environmental engineers has analyzed thirty years of data on Artic animal migration and movements. The results show that animals in one of the planet’s coldest regions are changing their behavior because of climate change.
The database used to make this discovery has records from ecologists around the world. It house more than 200 research projects tracking the movements of more than eight thousand land and marine animals between 1991 and present.
Scientists have been watching the warming of the Artic since the 1970s. According to research, the Artic has warmed 2.3 degrees C since then.
Increasing human development, shrinking ice, warmer winters and earlier springs are all affecting how native animals are behaving, according to researchers. An additional three studies using the same data demonstrates long-term, large-scale behavioral changes in caribou, bears, golden eagles, moose and wolves.
While ecologists have been watching specific species and specific animals for years this database is the first comprehensive source in terms of breadth of subjects and time studied. The databases includes data from various academic researchers, private and government organizations.
