Published Black summer bushfires in Australia wiped $2.8 billion from tourism supply chain



First input-output economic analysis of the 2019-20 Australian fires also found 7300 jobs were lost. The study highlights economic vulnerabilities to extremes of climate change.
Published Geoengineering may slow Greenland ice sheet loss



Modeling shows that stratospheric aerosol injection has the potential to reduce ice sheet loss due to climate change.
Published New research shows how pollutants from aerosols and river run-off are changing the marine phosphorus cycle in coastal seas



New research sheds light on how pollutants from aerosols and river run-off are impacting coastal seas. The research identified an 'Anthropogenic Nitrogen Pump' which changes the phosphorus cycle and therefore likely coastal biodiversity and associated ecosystem services.
Published Some plastic straws degrade quicker than others



Not all plastics are created the same, and some last longer in the ocean than others. Scientists have been working for years to quantify the environmental lifetimes of a wide range of plastic goods to see which have the shortest and longest lifespans in the ocean. To determine what plastics persist in the ocean, the team tests different products in large tanks that recreate the natural ocean environment.
Published Rising sea levels could lead to more methane emitted from wetlands



A Bay Area wetlands ecosystem that was expected to serve as a carbon sink is emitting surprisingly high levels of methane, a potent greenhouse gas. The study suggests factors governing carbon cycles in these habitats are even more complex than we thought.
Published First-ever sighting of a live newborn great white



Great whites, the largest predatory sharks in the world with the most fatal attacks on humans, are tough to imagine as newborn babies. That is partially because no one has seen one in the wild, it seems, until now.
Published How waves and mixing drive coastal upwelling systems



Large coastal upwelling systems along the eastern margins of the Atlantic and Pacific Oceans are among the most biologically productive and biodiverse regions of the world's oceans. Typically, the strength and timing of upwelling in such systems are linked to the prevailing winds. Interestingly, in some tropical regions, high levels of productivity occur even when the upwelling favorable winds are weak.
Published Achieving sustainable urban growth on a global scale



An international group of leading scientists call for an urgent change in the governance of urban expansion as the world's cities continue to grow at unprecedented rates.
Published West Nile virus emergence and spread in Europe found to be positively associated with agricultural activities



The spread of West Nile virus in Europe is strongly linked to agricultural activities, urbanization, and bird migration, according to new research.
Published Tiny ant species disrupts lion's hunting behavior



Data gathered through years of observation reveal an innocuous-seeming ant is disrupting an ecosystem in East Africa, illustrating the complex web of interactions among ants, trees, lions, zebras and buffaloes.
Published Unexpected biodiversity on the ocean floor



Hydrothermal vents and manganese nodule fields in the deep oceans contain more biodiversity than expected.
Published Global warming has a bigger effect on compact, fast-moving typhoons



A group has found that larger, slow-moving typhoons are more likely to be resilient to the effects of global warming. However, more compact, fast-moving storms are more likely to be sensitive. These findings suggest an improved method for projecting the strength of typhoons under global warming conditions.
Published War in Ukraine severely limits ability to track Arctic climate change



Scientists no longer have direct access to data from Russian Arctic research stations. Without this data, our view of climate changes in the region is increasingly biased, new research shows.
Published Paper provides a clearer picture of severe hydro hazards



A new study now provides a global examination of drought-pluvial volatility -- or the tendency to shift from one weather extreme to another.
Published A large percentage of European plastic sent to Vietnam ends up in nature



Despite strict EU regulations on plastic recycling, there is little oversight on plastic waste shipped from the EU to Vietnam. A large percentage of the exported European plastic cannot be recycled and gets dumped in nature, according to recent research.
Published Marine heat waves trigger shift in hatch dates and early growth of Pacific cod



Marine heat waves appear to trigger earlier reproduction, high mortality in early life stages and fewer surviving juvenile Pacific cod in the Gulf of Alaska, a new study shows. These changes in the hatch cycle and early growth patterns persisted in years following the marine heat waves, which could have implications for the future of Gulf of Alaska Pacific cod, an economically and culturally significant species.
Published When conditions cool down, a bacterial prey species becomes the predator



In a new study, two species of bacteria grown in a lab reversed their predator-prey relationship after one species was grown at a lower temperature.
Published Three-year population study supports fight to save Cameroon's Kordofan giraffe



Crucial new data about the numbers of Critically Endangered Kordofan giraffe living within Cameroon's B nou National Park has been released, supporting conservation efforts to save the subspecies from extinction.
Published Blue tit population booms with moths on the menu



Researchers found that years when moth numbers were up resulted in increased population growth for the blue tit.
Published Gulls swap natural for urban habitats, machine-learning study finds



The study is the first of its kind to compile a three-year dataset using a citizen science-based, opportunistic research method to include a large sample of gulls and other sub-Arctic birds in urban Alaska. The study provides a current snapshot of the habitat shift to an urban landscape.
