Earth’s various ecosystems, with all their plants and animals, will need to shift about a quarter-mile per year on average to keep pace with global climate change, scientists said in a study.How well particular species can survive rising worldwide temperatures attributed to excess levels of heat-trapping “greenhouse” gases emitted by human activity hinges on those species’ ability to migrate or adapt in place.

A weak cosmic infrared radiation field that reaches Earth from all directions contains not yet deciphered messages about the evolution of galaxies. Using first observations with the PACS Instrument on board ESA’s Herschel Space Telescope, scientists from the Max Planck Institute for Extraterrestrial Physics and other institutions have for the first time resolved more than half of this radiation into its constituting sources. Observations with Herschel open the road towards understanding the properties of these galaxies, and trace the dusty side of galaxy evolution.
