When the strong winds that circle the Arctic slacken, cold polar air can escape and cause extreme winter chills in parts of the Northern hemisphere. A new study finds that these weak states have become more persistent over the past four decades and can be linked to cold winters in Russia and Europe.
Plant-pollinator relationships are vital to our natural and agricultural ecosystems, with an incredible amount of food crops worldwide dependent on plant-pollinator interaction success. But the advancement of climate change is disrupting plant-pollinator relationships. A special issue of Applications in Plant Sciences -- Studying Plant-Pollinator Interactions Facing Climate Change and Changing Environments -- explores the creative methods being used by researchers to study the effects of climate change on plant-pollinator relationships.
Woody vegetation, such as trees and shrubs, has increased dramatically in Ozark grasslands over the past 75 years, according to a study published this week in the journal Landscape Ecology. If these ecosystems continue to favor woody vegetation, will it be possible to maintain open grasslands for the foreseeable future?
Reducing tourist consumption of reef fish is critical for Palau's ocean sustainability, finds a new UBC study that suggests other small island nations might also consider adopting this strategy.
We must move faster towards a low-carbon world if we are to limit global warming to 2 degrees C this century, experts have warned.
Three-quarters of counties in the contiguous United States present suitable environmental conditions for at least part of the year for either Aedes aegypti or Aedes albopictus mosquitoes to survive if introduced, according to researchers at the US Centers for Disease Control and Prevention. The two mosquito species can transmit viruses that cause Zika, dengue, chikungunya, and yellow fever.
Reducing tourist consumption of reef fish is critical for Palau's ocean sustainability, finds a new Nippon Foundation-UBC Nereus Program study published today in Marine Policy. While climate change is expected to lead to sharp declines in Palau's reefs, the best tourism management strategy includes a more than 70 per cent reduction in reef fish consumption by visitors. These findings are highly relevant for sustainable development in small island developing states under climate change.
The onset of the last ice age may have forced some bird species to abandon their northerly migrations for thousands of years, says new research led by a University of Nebraska-Lincoln ornithologist. Published Sept. 20 in the journal Science Advances, the study challenges a long-held presumption that birds merely shortened their migratory flights when glaciers advanced south to cover much of North America and northern Europe about 21,000 years ago.
The rainfall over the Yangtze River valley in the summer of 2016 was much weaker than that in 1998, despite the intensity of the 2016 El Nino having been as strong as that in 1998. A group of scientists from the Institute of Atmospheric Physics, Chinese Academy of Sciences, have now revealed the remarkable role played by the mid-latitude circulation in this surprising feature.
Sea surface temperature forcing can explain about two-thirds of heat wave variability and the other third comes from atmospheric internal variability during 1979-2008.
