Science of Global Warming and Climate Change – Why is it Important?

Posted on: Nov 15, 2022

Human activities are causing climate changes which appear to be determining the biologic future of Earth. These attributions are possible because of the study of the science of climate change. It is possible to forecast the implications of future human activities on climate, the environment and nature, and develop strategies to avoid the most undesirable outcomes and develop adaptation strategies for those outcomes that cannot be avoided. Failure to respond in a timely fashion will result in the next great extinction of life the Earth, the Holocene or sixth extinction. This is a legacy the current generation does not want. The ability to limit the impacts of climate change requires the global community minimize and possibly eliminate the use of fossil fuels – replacing them with renewable energy sources and so stop the emission of greenhouse gasses and aerosols that are causing global warming and climate change. This endeavor comes at a cost that requires support from all citizens of the global community and is only possible if the citizens are informed.
