While some people have little anxiety about the Earth's changing climate, others are experiencing high levels of stress, and even depression, based on their perception of the threat of global climate change, researchers found. Psychological responses to climate change seem to vary based on what type of concern people show for the environment, with those highly concerned about the planet's animals and plants experiencing the most stress.
The scrawny black spruce trees that push up through the peat bogs of Canada's boreal forest are valuable indicators of fire risk, say researchers who studied a burned-over area just outside Fort McMurray, Alberta, where a devastating wildfire struck in 2016.
Financial aid to fisheries in developing countries has declined by 30 percent, finds a new study from UBC and Stockholm Resilience Centre researchers, published in Marine Policy. Projects focusing on climate issues in fisheries had a 77 percent decline over the five years studied.
Ocean sediments are a massive storehouse for the potent greenhouse gas methane. But methane only acts as a greenhouse gas if and when it reaches the atmosphere. Environmental scientists at the University of Rochester and their collaborators recently set out to discover whether or not this ancient-sourced methane, which is released due to warming ocean waters, survives the journey from the seafloor and reaches the atmosphere.
California sea lions have fully rebounded under the protection of the Marine Mammal Protection Act, with their population on the West Coast reaching carrying capacity in 2008 before unusually warm ocean conditions reduced their numbers, according to the first comprehensive population assessment of the species.
Uncertainty surrounding the extent of future climate change could be dramatically reduced by studying year-on-year global temperature fluctuations, new research has shown.
Aerosol indirect effect (AIE) can significantly affect climate change and is one of the largest uncertainties in climate change studies. To date, only a few AIE studies using satellite measurements have been carried out in China, and no such study has been done using ground-based measurements. The AIE can only be assessed accurately from aircraft or ground-based measurements. The first comprehensive investigation into the AIE over this polluted region is presented.
Some Antarctic fish living in the planet's coldest waters are able to cope with the stress of rising carbon dioxide levels the ocean. They can even tolerate slightly warmer waters. But they can't deal with both climate change stressors at the same time, according to a study from the University of California, Davis.
Microwaves usage across the EU alone emits as much carbon dioxide as nearly seven million cars according to a new study by the University of Manchester. Researchers at the university have carried out the first ever comprehensive study of the environmental impacts of microwaves, considering their whole life cycle, from 'cradle to grave.'
Climate change has scientists worried that birds' annual migration and reproduction will be thrown out of sync with the seasons. Because birds' songs are correlated with their breeding behavior and are easily identifiable to species, monitoring birdsong can be a good way to keep tabs on this possibility, and a new study from The Condor: Ornithological Applications takes advantage of this approach to provide new baseline data for the birds of northern California.
