14-06-21 Global warming is generally expected to bring spring forward but, as a new study at Ludwig-Maximilians-Universitaet (LMU) in Munich shows, a concomitant（相伴的） influx of plant species from warmer southern latitudes could counteract this effect. C...

14-06-16 Climate change is unlikely to lead to more days of extreme cold, similar to those that gripped the USA in a deep freeze last winter, new research has shown. The Arctic amplification phenomenon refers to the faster rate of warming in the Arctic compa...

14-06-12 For the last 2.5 million years, our planet has experienced cold and warm, millennia-long cycles that collectively have become known as the Ice Age. During cold periods, continental-scale ice sheets blanketed large tracts of the northern hemisphere....

14-06-11 New research reveals that Caribbean corals and the algae（海藻） that inhabit them form a remarkably stable relationship -- new knowledge that can serve as an important tool in preserving and restoring vital reef-building corals. A scientific paper...

14-06-08 Hi, everybody. I'm here at Children's National Medical Center in Washington, D.C., visiting with some kids being treated here all the time for asthma（哮喘） and other breathing problems. Often, these illnesses are aggravated（加重，恶化） by air po...

14-06-06 Scientists know that wildland fire emissions play a significant role in the global carbon cycle and that its principal component -- carbon dioxide -- is a primary driver of climate change. But predicting and quantifying the effects of potential futu...

14-06-06 Fish and aquatic（水生的） life living in the high seas（公海） are more valuable as a carbon sink than as food and should be better protected, according to research from the University of British Columbia. The study found fish and aquatic life remo...

14-05-28 Butterflies and dragonflies（蜻蜓） with lighter colours are out-competing darker-coloured insects in the face of climate change. In a new study published in Nature Communications, scientists from Imperial College London, Philipps-University Marburg...

14-05-23 Whether an insect will have a male or female offspring depends on the weather, according to a study led by Joffrey Moiroux and Jacques Brodeur of the University of Montreal's Department of Biological Sciences. The research involved experimenting wit...

14-05-21 Many have assumed that warmer winters as a result of climate change would increase the growth of trees and shrubs（灌木） because the growing season would be longer. But shrubs achieve less yearly growth when cold winter temperatures are interrupted...
