What Does David Suzuki See as the Problem Regarding Climate Change?
Life on Earth is possible because of the warmth of the sun. While some of this incoming solar radiation bounces back into space, a small portion of it is trapped by the delicate balance of gases that make up our atmosphere. Without this layer of insulation, Earth would simply be another frozen rock hurtling through space. Carbon dioxide (CO2) is the most important gas in this layer of insulation.
These impacts also pose incalculable economic risks that far outweigh the economic risks of taking action today.
This time can span up to millions of years (Gillard, 12). These changes are caused by biotic processes and solar radiation variation which the earth receives. Other causes of climatic change are volcanic eruptions and plate tectonics. Human activities can also cause climatic change. Nevertheless, in modern times, climate change has come to be known as ‘Global Warming’. The evidence given in response to the changes in the global climate is drying rivers, drying trees and animal deaths as given above. Penguins have tried to adopt in the changing warm weather even though their habitat requires ice. Droughts, famines and other environmental issues have arisen because of global warming. Sicknesses such as some skin disease have been caused by global warming. Lung infections, sight problems and heart disease have also been given as evidences of global warming.
