Giant snakes warming to U.S. climes
Some were pets whose bodies and appetites apparently got too big for their owners to support. Most are probably descendants of released pets. Today, thousands of really big non-native snakes — we’re talking boa constrictors, anacondas and pythons — slither wild in southern Florida. And there’s nothing holding them in the Sunshine State. Which is why a report that was released today contends they pose moderate to high ecological threats to states on three U.S. coasts. Indeed, the homelands of these snakes share climatic features with large portions of the United States — territory currently inhabited by some 120 million Americans. Based on comparisons of the temperatures, rainfall and land cover found in the snakes’ native range, it’s possible that these slithering behemoths could stake claims to territory as far north as coastal Delaware and Oregon.

EPA: Greenhouse gases still endanger health
In April, the Environmental Protection Agency announced that based on its reading of the science, greenhouse gases threaten public health. Since then, the public and legions of interest groups have weighed in on the subject, shooting EPA some 380,000 separate comments. “After a thorough examination of the scientific evidence and careful consideration of public comments on the ruling,” EPA today reiterated its so-called “endangerment” assessment of greenhouse gases
