Is it natural to change timing of natural events ?

Climate change is a ‘heated’ issue at the moment and we all now know that average temperatures have already risen roughly by 1° and are predicted to rise more by up to 6° by the end of this century. The already apparent changes in our ecosystems are geographical range shifts, phenology of organisms, ecosystem functioning and composition.

Latitudinal and altitudinal limits of many species are dictated by climate. Thanks to pre- and post-glacial projections, we know that in the past whole biomes had shifted – New York used to be tundra but now is covered in temperate deciduous forest, and tundra moved further north. With current temperature rise, changes like these might not stay only a legacy of the past…
