Climate change is affecting the world in many ways. But attempts to directly link local changes in species distribution and biodiversity to climate warming hold little promise, ecologists warn in Nature Climate Change. First author Camille Parmesan, a population biologist at the University of Texas in Austin, explains why.
In his popular 2008 book Climate Wars, the US journalist and military historian Gwynne Dyer laid out a daunting scenario. Climate change would put growing pressure on fresh water and food over the coming century, he wrote, triggering social disorder, mass migration and violent conflict.
The humble Antarctic krill (Euphausia superba) bears a heavy burden. It may be just a small, shrimp-like crustacean, but its sheer abundance makes it one of the largest protein sources on Earth, eagerly sought by fish, penguins, whales
Driven by efforts to curb fossil-fuel use and concerns about the security of energy supplies, the number of applications for renewable-energy patents is booming. But the patents are scattered across many databases, in different formats that are not readily searchable, leading to a lack of clarity over who owns specific energy-technology patents, and in which regions.
Like any other field, research on climate change has some fundamental gaps, although not the ones typically claimed by sceptics. Quirin Schiermeier takes a hard look at some of the biggest problem areas.
