On Dec. 7, cold Arctic air (dark blue) descended into the Plains states and reached Colorado, Kansas and Missouri. That cold air shifted east on Dec. 9 into the Ohio Valley and New England.Credits: NASA JPL, Ed Olsen Imagery and...
The towering, hundred-year-old Sitka spruce trees growing in the heart of Vancouver Island's Carmanah Valley appear placid and unchanging. In reality, each one is packed to the rafters with evolutionary potential.
Climate-related changes in flower diversity have resulted in a decrease in the length of alpine bumble bees' tongues, a new study reports, leaving these insects poorly suited to feed from and pollinate the deep flowers they were adapted to...
Groundwater pumping in the last century has contributed as much as 50 percent to stream flow declines in some U.S. rivers, according to new research led by a University of Arizona hydrologist. The new...
A new study from The Australian National University (ANU) has shown the impact phosphate mining is having on our coral reefs. The study looked at coral reefs around Christmas Island, where there's been extensive phosphate mining...
Many pesticides that have been banned or are being phased out in the EU, Brazil and China, are still widely used in the USA, according to a study published in the open access journal Environmental Health.
Global temperatures showing the change from pre-industrial times. The global temperatures for January to September 2016 were approximately 1.2°C above pre-industrial levels and 0.88°C (1.58°F) above the average for the 1961-1990 reference period.Credit: NOAA; NASA/ UK Met Office; CRU It...
Feline hyperthyroidism is the most common endocrine-related disease of older cats, and its prevalence has skyrocketed since the first case was diagnosed in 1979. At the same time, new household flame retardants were introduced, and recently, scientists...
A new study led by researchers at the Universities of Bristol, Exeter, and Bath helps to shed light on the winter weather we may soon have in store following a dramatic meteorological event currently unfolding high above...
Researchers at McMaster University who rush in after storms to study the behaviour of spiders have found that extreme weather events such as tropical cyclones may have an evolutionary impact on populations living in storm-prone regions, where...
Wind erosion has been ruled out as the primary cause of methane gas release on Mars, Newcastle University academics have shown. Methane can be produced over time through both geological and biological routes and...
