Science Climate Change and Evolution Introduction The ecological consequences of global climate change are expected to be drastic although not much is known as to how individual species will react to these changes. Irrespective of the causes of climate change, whether anthropogenic or natural, it is imperative that we address these concerns, as they will have widespread impacts on the human species, both directly and indirectly through forcing on other species. The climate is not expected to shift evenly and the ways in which certain species adapt or migrate due to these changes could be erratic and unpredictable. The rate at which the earth’s climate is currently changing is unprecedented and has not been seen in the past 450,000 years. Although many species have simply migrated northward or vertically up mountainsides to escape warming habitats, others do not have this luxury or cannot migrate fast enough to survive. The earth’s temperature has risen by over one degree Fahrenheit over the past century, based on land and sea level measurements.
