Canceled Experiment to Block the Sun Won’t Stop Rich Donors from Trying

A botched geoengineering experiment to limit the amount of sunlight hitting Earth hasn’t dimmed donors’ enthusiasm for funding the research

CLIMATEWIRE | Wealthy philanthropists with ties to Wall Street and Silicon Valley are unbowed by a botched climate experiment to limit the amount of sunlight hitting the earth, vowing to continue bankrolling future solar geoengineering tests as temperatures catapult upward.

POLITICO contacted a dozen people or groups who funded a controversial program by the University of Washington to reflect sun rays by altering clouds. Those who responded indicated that it’s worth pushing through the public skepticism surrounding efforts to determine how to best deploy the last-ditch global warming fix — if at all.

“The Pritzker Innovation Fund believes in the importance of research that helps improve climate models and enables policymakers and the public to better understand whether climate interventions like marine cloud brightening are feasible and advisable,” Rachel Pritzker, the fund’s founder and president, said in a statement. “We will only get answers to these questions through open research that can inform science-based, democratic decision-making.”

The funders’ comments came after two high-profile experiments were shutdown following public backlash, pointing to the challenges of conducting controversial research that could result in weather disruptions or other unintended consequences. The latest experiment was derailed earlier this month when local officials in Alameda, California, rejected a request by Washington researchers to restart a test to brighten clouds from the deck of a decommissioned aircraft carrier in San Francisco Bay.
