While many species are migrating toward the poles as the climate warms, many North American and European bee species are failing to colonize new habitats, according to a new study. “Climate change is crushing [bumblebee] species in a vice,” says ecologist Jeremy Kerr, the study's lead author. “There's no way you can nail a bee with neonicotinoids, invasive pathogens, and climate change and come out with a happy bee.”

If you take a healthy 20 year-old, force them to sit all day, and refuse to let them do any physical labor out of fear they might hurt themself, it would cause them to “age” extremely rapidly. We need to promote more, not less physical activity for our elders. The next time you consider telling your grandmother to sit down, think about whether that’s really in her best interest.

In recent decades, of course, the Republicans have lurched rightward on many topics and now regularly attack scientific findings that threaten their political platforms. In the 1980s, they generally questioned evidence of acid rain; in the 1990s, they went after ozone science; and in this century, they have launched fierce attacks not just on climate science, but in the most personal fashion imaginable on climate scientists.

Dr. Oreskes’s core discovery, made with a co-author, Erik M. Conway, was twofold. They reported that dubious tactics had been used over decades to cast doubt on scientific findings relating to subjects like acid rain, the ozone shield, tobacco smoke and climate change. And most surprisingly, in each case, the tactics were employed by the same group of people.

If a study doesn’t even list how many people took part in it, or makes a bold diet claim that’s “statistically significant” but doesn’t say how big the effect size is, you should wonder why. But for the most part, we don’t. Which is a pity, because journalists are becoming the de facto peer review system. And when we fail, the world is awash in junk science.
