The case for optimism on climate change

Human activity pours over 100 million tons of heat-trapping pollution into the atmosphere every day, fueling record storms, droughts, and floods. Yet, renewable energy technologies like wind and solar are now growing exponentially, with costs dropping faster than predicted. The tipping point has arrived where clean energy outcompetes fossil fuels in many places, unleashing a wave of global investment. Facing a moral crossroads, society has the tools and momentum needed to solve the crisis and build a sustainable future.
