not a smidgen of evidence

To be clear: many now are claiming, in effect, that the world's best scientists, thousands of them, who have contributed to framing the statements on global warming issued by our own and most other governments, the IPCC, National Academy of Sciences, Royal Society, American Physical Society, and on and on, have been engaged for many decades in a massive, secret conspiracy. I don't think the stolen emails and computer code provide a smidgen of evidence for that.
