The discussion of climate change is so poisoned by politics that I just can't follow it. So r/askscience, I beg you, can you filter out the noise?

Caution: It is vitally important not to make connections. When you see pictures of rubble like this week's shots from Joplin, Mo., you should not wonder: Is this somehow related to the tornado outbreak three weeks ago in Tuscaloosa, Ala., or the enormous outbreak a couple of weeks before that (which, together, comprised the most active April for tornadoes in U.S. history). No, that doesn't mean a thing. It is far better to think of these as isolated, unpredictable, discrete events. It is not advisable to try to connect them in your mind with, say, the fires burning across Texas - fires that have burned more of America at this point this year than any wildfires have in previous years. Texas, and adjoining parts of Oklahoma and New Mexico, are drier than they've ever been - the drought is worse than that of the Dust Bowl. But do not wonder if they're somehow connected.

"In 2009, the scientific literature caught up with what top climate scientists have been saying privately for a few years now: * Many of the predicted impacts of human-caused climate change are occurring much faster than anybody expected - particularly ice melt, everywhere you look on the planet. * If we stay anywhere near our current emissions path, we are facing incalculable catastrophes by century's end, including rapid sea level rise, massive wildfires, widespread Dust-Bowlification, large oceanic dead zones, and 9°F warming - much of which could be all but irreversible for centuries. And that's not the worst-case scenario! * The consequences for human health and well being would be extreme. That's no surprise to anybody who has talked to leading climate scientists in recent years, read my book Hell and High Water (or a number of other books), or followed this blog. Still, it is a scientific reality that I don't think more than 2 people in 100 fully grasp, so I'm going to review here the past year in climate science. I'll focus primarily on the peer-reviewed literature, but also look at some major summary reports."

Ah what a wonderful world we live in - a world where giant agricultural producers regularly feed arsenic to chickens. This, mind you, isn't how they kill the chicken. No, it's how they make them grow bigger, faster, cheaper. Administered in small amounts, arsenic is one of many compounds found in various drugs routinely administered to chickens in their feed. These same giant agricultural producers have maintained for years that the arsenic never makes its way into the actual chicken meat sold at the supermarket. It all gets pooped out! Or so they say. Yet if that's the case, then why did the FDA recently admit that arsenic does, in fact, show up in supermarket chickens?

Scientists have become increasingly worried that even extremely low levels of some environmental contaminants may have significant damaging effects on our bodies-and that fetuses are particularly vulnerable to such assaults. Some of the chemicals that are all around us have the ability to interfere with our endocrine systems, which regulate the hormones that control our weight, our biorhythms and our reproduction. Synthetic hormones are used clinically to prevent pregnancy, control insulin levels in diabetics, compensate for a deficient thyroid gland and alleviate menopausal symptoms. You wouldn't think of taking these drugs without a prescription, but we unwittingly do something similar every day.  An increasing number of clinicians and scientists are becoming convinced that these chemical exposures con­tribute to obesity, endometriosis, diabetes, autism, allergies, cancer and other diseases. Laboratory studies-mainly in mice but sometimes in human sub­jects-­have demonstrated that low levels of endocrine-disrupting chemicals in­duce subtle changes in the developing fetus that have profound health effects in adulthood and even on subsequent generations. The chemicals an expecting mother takes into her body during the course of a typical day may affect her children and her grandchildren.
