Charges by critics that scientists won’t release their raw data so that others might independently vet published analyses of climate trends. Taken together, these events have marred the reputations of climate scientists, the Intergovernmental Panel on Climate Change and perhaps science generally. Or so concluded a distinguished panel of science luminaries.
