This document discusses the impacts of climate change and outlines two potential scenarios for the future: continuing with business as usual or taking dramatic action to address climate change. It warns that the business as usual approach could have catastrophic consequences, including rising sea levels that flood many coastal cities, more frequent extreme heat waves, changing weather patterns that impact agriculture, and potential tipping points like the melting of ice sheets. It advocates for a major "home makeover" approach with 55 recommendations to improve energy efficiency, reduce emissions, and transition to cleaner energy sources to create a safer and more sustainable future. It asks students what they can do to help address the climate crisis.
