Wind turbines contribute to climate change: study

WASHINGTON, United States (AFP) — Wind turbines, designed as an alternative to fossil fuels, still contribute to climate change due to the way they redistribute heat and moisture in the atmosphere, according to a study published Thursday. Researchers from Harvard University found that powering the entire United States with wind energy would cause a 0.54 degree Celsius ground temperature rise in the area where the turbines were located, and a 0.24C increase across the continental […]

Thai bay made famous in ‘The Beach’ shut indefinitely

BANGKOK, Thailand (AFP) — The glittering Thai bay immortalized in the movie “The Beach” will be closed indefinitely to allow it to recover from the impact of hordes of tourists, an official said Wednesday, as a temporary ban on visitors expired. Maya Bay, ringed by cliffs on Ko Phi Phi Ley island, was made famous when it featured in the 2000 film starring Leonardo DiCaprio. It was initially shut for four months in June due […]

New species of hummingbird identified in Ecuador

QUITO, Ecuador (AFP) — A team of ornithologists in Ecuador has identified a new species of hummingbird: a lovely blue-green creature that lives in a cold, barren highland area and is danger of extinction. Team leader Francisco Sornoza saw one of the birds through binoculars a year ago and had a hunch that it was a previously unknown species. The bird is about 11 cm (four inches) long and has a stunning, deep blue neck, […]

Earthquake fear ends Dutch gas boom

by Charlotte VAN OUWERKERK Agence France Presse ZEERIJP, Netherlands (AFP) — The Dutch are proud of the way they have created a country by fighting back the ocean — but when they started making their own earthquakes it proved a step too far. The tiny village of Zeerijp in the northern Netherlands looks ordinary on the surface, yet closer inspection reveals cracks in homes, schools and historic buildings. A series of quakes caused by extractions […]

Propping up glaciers to avoid cataclysmic sea level rise

by Marlowe HOOD Agence France Presse PARIS, France (AFP) — As global warming outpaces efforts to tame it, scientists have proposed building massive underwater structures to prevent an Antarctic glacier the size of Britain from sliding into the sea and lifting the world’s oceans by several meters. The more modest of two engineering schemes — which is still on the scale of a Panama or Suez Canal — to shore up Thwaites Glacier would require […]

Even moderate warming could melt Antarctic ice sheet: study

by Patrick GALEY Agence France Presse PARIS, France (AFP) — Moderate global temperature rises of just two degrees Celsius could still be enough to melt parts of the largest ice sheet on Earth and raise sea levels by several metres, experts warned on Wednesday. As the pace of climate change rapidly outstrips mankind’s attempts to rein it in, scientists delved into the distant past of glaciers in eastern Antarctica to predict what lay in store […]

Air pollution linked to higher risk of dementia: study

PARIS, France (AFP) — Urban air pollution, mostly from vehicles, is associated with an increased risk of dementia, according to research published Wednesday. The link remained even after heavy drinking, smoking and other well established risk factors for dementia were ruled out, the researchers reported in medical journal BMJ Open. Worldwide, about seven percent of people over 65 suffer from Alzheimer’s or some form of dementia, a percentage that rises to 40 percent above the […]

Microplastics may enter foodchain through mosquitoes

  PARIS, France (AFP) — Mosquito larvae have been observed ingesting microplastics that can be passed up the food chain, researchers said Wednesday, potentially uncovering a new way that the polluting particles could damage the environment. Microplastics — tiny plastic shards broken down from man-made products such as synthetic clothing, car tyres and contact lenses — litter much of the world’s oceans. Hard to spot and harder to collect, they can seriously harm marine wildlife […]

Germany rolls out world’s first hydrogen train

BREMERVORDE, Germany (AFP) — Germany on Monday rolled out the world’s first hydrogen-powered train, signalling the start of a push to challenge the might of polluting diesel trains with costlier but more eco-friendly technology. Two bright blue Coradia iLint trains, built by French TGV-maker Alstom, began running a 100-kilometer (62-mile) route between the towns and cities of Cuxhaven, Bremerhaven, Bremervoerde and Buxtehude in northern Germany — a stretch normally plied by diesel trains. “The world’s […]

Melting permafrost threatens climate rescue plan: study

by Patrick GALEY Agence France-Presse Global targets aimed at warding off runaway planetary warming could be breached sooner than expected, experts warned Monday, as gases released by melting permafrost threaten to undermine human efforts to avert climate disaster. Under the current rescue plan, outlined in the 2015 Paris climate treaty, countries have agreed to limit global temperature rises to “well below” two degrees Celsius, and 1.5C if deemed possible. That course of action assumes that […]

Researchers turn to oysters as pollution-tracking sentinels

by Régine LAMOTHE Agence France Presse ARCACHON, France (AFP) — French researchers hoping to get an early warning on pollution in the ocean have found an unlikely ally in a mollusk more often destined for the dinner table. Their findings reveal that much like canaries in a coal mine, oysters stationed near offshore oil platforms can detect minute amounts of hydrocarbons as each one constantly filters dozens of gallons of water every day. That could […]
