Scientists from Cardiff University have found that Britain's urban rivers are the cleanest they've been in over two decades.
The 21-year study of over 2,300 rivers measured the presence of clean-river invertebrates - a yardstick for river health - which during the days of heavy industry and poor sewage treatment had declined considerably, but now appear to be making a comeback.
Although climate change has warmed British rivers by around 1-2 degrees over recent decades, the findings suggest that improved pollution control has managed to offset its damaging effects on river ecosystems. This indicates that society can prevent some undesirable climate change effects on the environment by improving habitat quality.

The virus that causes Middle East respiratory syndrome (MERS) has been found in camel milk. Scientists don’t know whether infected milk can sicken people, but experts say the results are reason enough to warn against drinking raw camel milk, a widespread tradition in the Middle East. The Qatari government has already issued new guidelines recommending that milk be boiled before consumption.
The new findings come from a group of researchers at Qatar's Supreme Council of Health; the country's Ministry of Environment; Erasmus MC in Rotterdam, the Netherlands; and the Dutch National Institute for Public Health and the Environment. They were announced at a press conference in Doha on Wednesday, and a paper about them was submitted to the journal Eurosurveillance today, says Erasmus MC virologist Chantal Reusken, the first author.

Astronomers have discovered a rocky planet that weighs 17 times as much as Earth and is more than twice as large in size. This discovery has planet formation theorists challenged to explain how such a world could have formed.
"We were very surprised when we realized what we had found," said astronomer Xavier Dumusque of the Harvard-Smithsonian Center for Astrophysics, Cambridge, Massachusetts, who led the analysis using data originally collected by NASA's Kepler space telescope.

A call by Brazilian scientists to protect the endangered mascot of the 2014 World Cup, the Brazilian three-banded armadillo, seems to have been heeded by the Brazilian government. On 22 May, the Brazilian government published an action plan to conserve this armadillo, which is unique to Brazil. The document proposes increasing the protected areas where the armadillo lives, enhancing financial incentives to prevent three-banded armadillo hunting and increasing education about the importance of protecting this species.

Coal consumption in China is likely to dwindle rapidly, writes Alex Kirby, leaving its own mining sector and foreign coal exporters in serious trouble. Australia and Indonesia are at greatest risk as China may soon stop importing any coal at all.
Investors need to dispel any belief that Chinese coal demand is insatiable, and integrate this transition into their decision-making.
Analysts believe that China - the world's largest producer and consumer of coal, accounting for almost half of global consumption - could be close to making an abrupt, drastic change of track.

The European Union’s greenhouse gas emissions have fallen by 19.2% compared to 1990s levels, according to the European Environment Agency.
EU emissions dropped 1.3% in 2012, reaching their lowest level ever recorded, according to data reported to the United Nations by the EEA. The bloc's greenhouse gas output decreased by 1082 megatonnes since 1990, more than the combined emissions of Italy and United Kingdom in 2012.

Populations of the popular Monarch butterfly have been declining in recent years and a new study is citing habitat loss on US breeding grounds as the main culprit. The eastern North American monarch population is known not only for its iconic orange and black colors, but also for its late summer migration from the United States to Mexico, a migration covering thousands of miles. And despite the long-held belief that monarch butterflies are most vulnerable to disturbances on wintering grounds in Mexico, new research from the University of Guelph shows lack of milkweed in the US which provides breeding grounds for the species is playing more of a role for species decline.

Barbados, a small Caribbean island at the cutting edge of the fight against climate change, will be hosting this year's World Environment Day, leading United Nations-wide efforts to draw attention to the plight of the world's small islands potentially in peril of being lost to sea-level rise.
"On World Environment Day, millions of individuals, community groups and businesses from around the world take part in local projects –from clean up campaigns to art exhibits to tree-planting drives," Secretary-General Ban Ki-moon said in his message for the Day, marked every year on 05 June.
