There’s a scene in Jerry Maguire where the title character, at his wits’ end following a particularly bad day at the office, laments, “Okay, just jump right into my nightmare. The water is warm.”

See, that warm water is the problem.

Leigh Steinberg, the real-life sports agent to the stars whom Jerry Maguire was based on, is worried. Worried about carbon emissions. Worried about global warming. Worried about being part of the first generation of humans in history to pass on a degraded quality of life to the next generation. Worried that the water is getting too warm. “As the poles break up and oceans rise and hurricanes intensify and weather changes and diseases reemerge … it’s incumbent on us to improvise methods of restructuring our lifestyles,” warns Steinberg.

Clearly, Steinberg—whose agency recently announced the formation of the Sporting Green Alliance (SGA), “the sporting world’s first and only environmental activism organization focused on ‘greening-up sports”—isn’t your everyday agent. He has no qualms holding forth on the perils facing our planet with Bill Nye the Science Guy fervor. For years, the nightmare was no one seemed to be listening. “I’ve been concerned about the imminent specter of global warming, species in peril, and the posture of denial as to the true and dire nature of the threat for some time,” says Steinberg. “We’ve only been here 130,000 years as a species, and as the dinosaurs had prodigious bodies but limited intellect, they couldn’t adapt to comet storms and environmental changes and thus went extinct. Humans, on the other hand, have prodigious intellects but greed and politics and multinational organizations have blinded us to the real nature of how rapidly global warming has occurred, and how urgent the need is to adapt.”
