    When to welcome ‘invading’ species

    As climate changes, some environments are becoming hostile to the flora and fauna that long nurtured them. Species that can migrate have begun to move into regions where temperatures and humidity are more hospitable. And that can prove a conundrum for officials charged with halting the invasion of non-native species, notes Jon Jarvis, a biologist who for the past year has headed the National Park Service.

    Warming is accelerating global water cycle

    Fresh water evaporates from the oceans, rains out over land and then runs back into the seas. A new study finds evidence that global warming has been speeding up this hydrological cycle recently, a change that could lead to more violent storms. It could also alter where precipitation falls — drying temperate areas, those places where most people now live.

    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.”
