Meta-Analysis on the Effects of Global Economic Growth on Birds in the Nations of the Three Poles
Economic and population growth as well as global macroeconomic policies are contributing to increasing global greenhouse gas (GHG) emissions. Climate change effects are more pronounced in cold regions such as the ‘Three Poles’ (the Arctic, the Antarctic and the Hindu Kush-Himalaya regions) than anyw...

Economic and population growth as well as global macroeconomic policies are contributing to increasing global greenhouse gas (GHG) emissions.

In the Three Poles, many species depend on ice and snow habitats, but these species are competing with human activities for space and resources on a finite globe.
