2023 NCF-Envirothon New Brunswick

 The earth’s climate is constantly changing and has been doing so for billions of years. Although long-term fluctuations in temperature are normal and greenhouse gasses are emitted to the atmosphere from both natural and human-generated sources, the vast majority of climate scientists agree that the global warming observed since the mid-20th century (1950s) is cause for immediate concern. Human-induced emissions of greenhouse gasses are being released at a quicker rate than natural processes can remove them¹. Not only do climate models project an increase in temperature, but the models also predict increases in the frequency of hot days above 30⁰C (86⁰F) as well as changes in precipitation, extreme weather events, sea level rise, water stress, and ocean acidification. As a result, disruptive changes to ecosystems, the economy, and society are expected to occur on both local and global scales.

The changing climate is one of the most complex issues facing the world today. It spans many disciplines and aspects of everyday life: science, socio-economics, environment, health, politics, as well as moral and ethical values. The impact on New Brunswick’s economy and quality of life for its citizens will depend on how effectively we plan and prepare for the complex challenges and changes that will occur.

Students will learn about factors contributing to a changing climate, the effects of these changes on the environment and natural resources, and the unique challenges facing natural resource dependent communities. As they explore the impacts on human social and economic systems, they will learn about management strategies for mitigating and adapting to a changing climate, and the roles of innovative technologies and programs in responding to local and global changes.
