Climate change has already caused huge changes to weather patterns in the Great Lakes and worldwide, strongly impacting ecosystems and challenging human infrastructure that was built for the less extreme climate of the 20th century. Climate change impacts will accelerate in the coming years, and the weather will grow hotter and more extreme until all emissions of heat-trapping greenhouse gases end. In this presentation, Jeff Masters will review how the climate of Michigan has changed in recent years, and make predictions on what the future of climate change will bring to the Great Lakes and to the world.
