Tributes have been flowing in recognition of the immense contribution to our movement made by Michael Mariotte, who died on May 16 after a long struggle with pancreatic cancer.  The Executive Director and then President of Nuclear Information and Resource Service, Mariotte was a keenly perceptive observer, savvy public advocate, and thorn in the side of the nuclear industry, its regulators, lobbyists and government lackeys.  He was also a leader in efforts to keep nuclear power off the table as a climate change solution.  Michael was a fearless, committed campaigner and a compelling and insightful writer who worked almost to his final days on his GreenWorld blog, calling out the corruption and collapse of the nuclear industry.
