Epidemics of dengue are linked to high temperatures brought by the El Niño weather phenomenon, a University of Florida scientist working with an international team of researchers has found.
New research shows that butterflies in Greenland have become smaller in response to increasing temperatures due to climate change.
'People intuitively know that frost can be bad,' said Amy Betz, a professor in mechanical engineering at Kansas State University. Betz and her colleagues have created a surface that can significantly delay frost formation, even at temperatures of down to 6 degrees Celsius below freezing. The surface is biphilic, meaning it repels water in some areas and attracts it in others. The researchers describe their results in a paper in the journal Applied Physics Letters.
New research by University of York academics reveals that living 'green' walls may have adverse health effects on office workers living in hot, polluted climates.
The more ice is melted of the Antarctic Filchner-Ronne shelf, the more ice flows into the ocean, and the more the region contributes to global sea-level rise. Unlike some some other parts of Antarctica, this region is not characterized by instabilities which, once triggered, can lead to persistent ice discharge into the ocean even without a further increase of warming. So for the Filchner-Ronne ice, this is a tiny bit of good news.
If the warming trend continues as projected in the Northern Rockies of the American West, the large wildfires of recent years could be just the start of more extensive and devastating blazes.
A new study assessing the influence of species diversity of canopy trees on the amount of ozone precursors a forest emits suggests that atmospheric chemistry models in use now may underestimate the importance of tree species mix and size to ozone pollution, says lead author Alexander Bryan, a postdoctoral fellow in the Northeast Climate Science Center at the University of Massachusetts Amherst.
In forests worldwide, drought consistently has had a more detrimental impact on the growth and survival of larger trees, new research shows. In addition, while the death of small trees may affect the dominance of trees in a landscape, the death of large trees has a far worse impact on the ecosystem and climate's health, especially due to the important role that trees play in the carbon cycle.
The sensitivity of leaf unfolding phenology to climate warming has significantly declined since 1980s, according to a study recently published in the journal Nature by an international collaboration of scientists. Earlier spring leaf unfolding is a frequently observed response of plants to climate warming. Many deciduous tree species require cold temperatures, in other words 'chilling', for dormancy release, and the warming-related reductions in chilling may counteract the advance of leaf unfolding in response to warming. Empirical evidence for this, however, was very limited.
Despite climate change, sea ice in the Northwest Passage remains too thick and treacherous for it to be a regular commercial Arctic shipping route for many decades, according to new research out of York University. Prior to this research, there was little information about the thickness of sea ice in the NWP. Next to ice coverage and type, sea ice thickness plays the most important role in assessing shipping hazards and predicting ice break-up.
