Identifying a cyanobacterial gene family that helps control photosynthesis
A new study has identified a family of genes in cyanobacteria that help control carbon dioxide fixation.

Heat waves could increase substantially in size by mid-century
Scientists found that by mid-century, in a middle greenhouse emissions scenario, the average size of heat waves could increase by 50%. Under high greenhouse gas concentrations, the average size could increase by 80% and the more extreme heat waves could more than double in size.
Read moreStudy of past California wildfire activity suggest climate change will worsen future fires
A new study finds that climate has been the dominant controller of wildfire activity in the Sierra Nevada region of the past 1,400 years, suggesting that future climate change is poised to make fires worse.
Read moreDual approach needed to save sinking cities and bleaching corals
Local conservation can boost the climate resilience of coastal ecosystems, species and cities and buy them time in their fight against sea-level rise, ocean acidification and warming temperatures, a study by scientists suggests. In all but extreme situations, these interventions significantly buffer the impacts of climate change and can buy sinking cities and bleaching corals time to adapt until the beneficial impacts of global emissions reductions kick in.
Read moreCosts of natural disasters are increasing at the high end
While the economic cost of natural disasters has not increased much on average, averages can be deceptive. The costs of major disasters like hurricanes Katrina, Maria and Dorian or the massive tornado swarms in the Midwest have increased to a disproportionately larger extent than those of lesser events, and these major disasters have become far more expensive, according to an international team of researchers.
Read moreAncient Maya canals and fields show early and extensive impacts on tropical forests
New evidence in Belize shows the ancient Maya responded to population and environmental pressures by creating massive agricultural features in wetlands, potentially increasing atmospheric CO2 and methane through burn events and farming, according to geographical research.
Read moreNew method gives first global picture of mutual predictability of atmosphere and ocean
Scientists have carried out a novel statistical analysis to determine for the first time a global picture of how the ocean helps predict the low-level atmosphere and vice versa. They observed ubiquitous influence of the ocean on the atmosphere in the extratropics, which has been difficult to demonstrate with dynamic models of atmospheric and oceanic circulation.
Read moreEarly breeding season for some Arctic seabirds due global warming
The breeding season of some seabirds in Arctic regions takes place earlier as a result of the temperature rise caused by climate change, according to a new article.
Read moreAnother casualty of climate change? Recreational fishing
Another casualty of climate change will likely be shoreline recreational fishing, according to new research. The study finds some regions of the U.S. may benefit from increasing temperatures, but those benefits will be more than offset by declines in fishing elsewhere.
Read moreDisappearing Peruvian glaciers
It is common knowledge that glaciers are melting in most areas across the globe. The speed at which tropical glaciers in the Peruvian Andes are retreating is particularly alarming, however. In the first detailed investigation of all Peruvian mountain ranges, a research team has ascertained a drastic reduction of almost 30 percent in the area covered by glaciers between 2000 and 2016.
