Climate’s link to plague
Scientists have correlated changes in long-term Pacific Ocean temperature patterns with the incidence of a deadly bacterial pestilence, one spread by fleas living on and around mice and other rodents.

Academies recommend that IPCC make changes
The Intergovernmental Panel on Climate Change, an authoritative scientific organization set up in 1989 to assess climate science, took some heat today from a group that it commissioned to investigate its credibility. The oversight group reported findings procedural weaknesses that preclude IPCC from responding nimbly to events — or from reliably identifying errors in its assessments.

EPA rejects climate-change deniers’ petitions
A number of people challenge that climate change is real, that it's due to greenhouse gases released by human activities and that it's a threat to human health and the environment. On July 29, the Environmental Protection Agency formally rejected those claims as it turned down 10 petitions asking the Obama administration to reconsider EPA’s “endangerment finding.”

EPA issues greenhouse-gas rules for new factories and more
EPA released new rules on greenhouse-gas emissions for new power plants, factories and oil refineries — any big new facility, really that emits huge amounts of carbon dioxide, methane, nitrous oxide, or any of several other classes of chemicals. Existing facilities can continue to spew greenhouse gases at current levels.
