Meanwhile, accusations of climate change censorship are now reaching the halls of the Smithsonian National Museum of Natural History in Washington. The Washington Post reports museum directors took steps to downplay global warming at an Arctic exhibit to avoid a political fallout. Museum director Cristián Samper imposed last-minute changes to the exhibit’s script that raised “scientific uncertainty” about climate change. The move came after Samper held up the project for six months, ordered reviews from other government agencies, and moved a climate change discussion in the exhibit to less prominence.
