The promise of Waterless Dyeing
June 13, 2014 07:56 AM - Lydia Heida, Yale Environment360

One of the world's most polluting industries is the textile-dyeing sector, which in China and other Asian nations releases trillions of liters of chemically tainted wastewater. But new waterless dyeing technologies, if adopted on a large scale, could sharply cut pollution from the clothing industry. Each year, one global industry gulps down trillions of liters of fresh water, together with massive amounts of chemicals. The wastewater from that industry is then dumped, often untreated, into rivers that bring its toxic content to the sea, where it spreads around the globe.

Hope for the Indian rhino

The world's stronghold for Indian rhinos—the state of Assam—has seen its population leap by 27 percent since 2006, despite a worsening epidemic of poaching that has also seen 156 rhinos killed during the same period. According to a new white paper, the population of Indian rhinos in Assam hit 2,544 this year up from a nadir of around 200 animals in the early 1900s.

Wasted heat from air conditioners causes warmer nighttime temperatures
June 12, 2014 08:01 AM - Allison Winter, ENN

With summer temperatures fast approaching, households across the country are installing and prepping air conditioning units in anticipation of hot, sticky weather. However, a potentially brutal cycle may be in store if summertime extreme-heat days are projected to become more frequent and intense as a result of climate change. According to a new study conducted in Phoenix by Arizona State University researchers, so much wasted heat is emitted by air conditioning units that it actually raises the city's outdoor temperature at night by 1-2.7 degrees! Consequently, these warmer temperatures may encourage individuals to further their demands and energy use of their air conditioners. The research, published last month in the Journal of Geophysical Research, investigates the effects of air-conditioning systems on air temperature and examines their electricity consumption for a semiarid urban environment.

Using too much fertilizer is bad for crops AND bad for climate!
June 12, 2014 06:30 AM - Roger Greenway, ENN

Using too much fertilizer is a very bad idea. It doesn't help crops, and in fact can be harmful to them. Excess fertilizer runs off and contributes to river and stream contamination and a new study shows that it is bad for the climate too! But farmers sometimes think that if some is good, more MUST be better! Helping farmers around the globe apply more precise amounts of fertilizer nitrogen is a great objective that can improve crop yields, reduce pollution, and combat climate change. That's the conclusion of a study published this week in the journal Proceedings of the National Academy of Sciences. In the paper, researchers at Michigan State University (MSU) provide an improved prediction of nitrogen fertilizer's contribution to greenhouse gas emissions from agricultural fields.

Geothermal heat is causing the West Antarctic glacier to melt faster
June 10, 2014 07:37 AM - University of Texas at Austin via EurekAlert

Thwaites Glacier, the large, rapidly changing outlet of the West Antarctic Ice Sheet, is not only being eroded by the ocean, it's being melted from below by geothermal heat, researchers at the Institute for Geophysics at The University of Texas at Austin (UTIG) report in the current edition of the Proceedings of the National Academy of Sciences. The findings significantly change the understanding of conditions beneath the West Antarctic Ice Sheet where accurate information has previously been unobtainable.

In cutting deforestation, Brazil leads world in reducing emissions
June 9, 2014 08:53 AM - Rhett A. Butler, MONGABAY.COM

Brazil's success in reducing deforestation in the world's largest rainforest has been much heralded, but progress may stall unless farmers, ranchers and other land users in the region are provided incentives to further improve the environmental sustainability of their operations, argues a study published this week in the journal Science.

Bottom feeding fish helping the fight against Global Warming
June 9, 2014 07:48 AM - Steve Williams, Care2

Over-fishing is already a concerning problem, but new research indicates that not only could it mean losing fish species, it could also contribute to global warming more than we'd previously thought. That's because researchers from the Marine Institute and the University of Southampton have found that fish that feed on our ocean floor and do not come to the surface actually act as carbon sinks. Other examples of naturally occurring carbon sinks include forests and, indeed, the oceans themselves. What’s more, the UK-based researchers have found that deep-sea fish might be capturing more than a million tons of carbon dioxide from UK and Irish waters.

Good news for rivers in Britain
June 8, 2014 11:11 AM - Cardiff University via ScienceDaily

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.

China and Coal
June 6, 2014 06:56 AM - Alex Kirby, The Ecologist

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.

CO2 emissions in EU down significantly
June 5, 2014 03:47 PM - EurActiv

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.
