Climate change: can hummingbirds take the heat?

by Marlowe HOOD Agence France Presse PARIS, France (AFP) — Extreme heat sometimes forces hummingbirds to seek shade instead of foraging for food, researchers said Wednesday, warning that global warming could test the tiny birds’ capacity to adapt. With hearts beating more than 1,000 times a minute, hummingbirds need to feed constantly, which means they can ill afford to spend time dodging sunshine, according to a report in the journal Royal Society Open Science. “They […]

Global warming outpacing current forecasts: study

by Marlowe Hood Agence France Presse PARIS, France (AFP) — The UN’s forecast for global warming is about 15 percent too low, which means end-of-century temperatures could be 0.5 degrees Celsius higher than currently predicted, said a study released Wednesday. The prediction makes the already daunting challenge of capping global warming at “well under” 2.0 degrees Celsius (3.6 degrees Fahrenheit) — the cornerstone goal of the 196-nation Paris Agreement — all the more difficult, the […]

Australian dogs trained to sniff out endangered species

SYDNEY, Australia (AFP) — Australian dogs are being trained to sniff out the droppings of endangered animals in a scheme that offers greater understanding of threatened species through the less-intrusive method of canine tracking. Emma Bennett, a PhD candidate at Monash University in Melbourne, is working with environmentally-conscious dog owners who have volunteered their pets in a rainforest region of Victoria state to track the scats, or droppings, of the endangered tiger quoll, a small […]

India, Sri Lanka cyclone death toll rises to 26

COLOMBO, Sri Lanka (AFP) — Thousands took to relief camps in Sri Lanka and southern India on Saturday to escape rising floodwaters after a cyclone killed at least 26 people. Cyclone Ockhi has left 13 people dead in Sri Lanka and killed an equal number in India’s Kerala and Tamil Nadu states since Friday as it churns in the Arabian Sea. Eleven people, mostly fishermen, remained missing in the two countries as nearly 9,000 people […]

Scallops have 200 eyes, which function like a telescope: study

MIAMI, United States (AFP) — Scallops may look like simple creatures, but the seafood delicacy has 200 eyes that function remarkably like a telescope, using living mirrors to focus light, researchers said Thursday. Most creatures’ eyes have lenses that focus light. But scallops have concave mirrors at the back of their eyes. Scientists have known since the 1960s that Pecten scallops see by reflecting light off these concave mirrors onto the retina above, said the […]

65-million-year-old turtle fossil found in Mexico

SALTILLO, Coahuila, Mexico (Reuters) — The fossilized remains of a turtle thought to be 65 million years old has been discovered in Mexico’s arid north, shedding new light into life into the once lush desert areas of Coahuila. The turtle fossil dubbed the “Yelmochelis rosarioae” is one of the smallest animals to have roamed this ancient area, measuring just 10 centimeters (under 4 inches). Despite its size, the thickness of its shell and its ability […]

Scientists discover resilient ‘heart’ of Great Barrier Reef

MIAMI, United States (AFP) — Australia’s Great Barrier Reef is in peril from climate change and widespread bleaching, but scientists said Tuesday a small portion may be resilient enough to keep much of the rest alive. About three percent of the World Heritage site — home to the planet’s largest collection of coral reefs with 3,800 in all — has so far emerged relatively unscathed from a host of threats, from warming waters to pollution […]

Fur flies as cheetah races electric Formula E car

WESTERN CAPE, South Africa (Reuters) — The cheetah is renowned for being the world’s fastest mammal but is also one of its most endangered species. Recently the organizers of the environmentally-friendly Formula E racing series set up a race between one of their cars and a tame cheetah to highlight the impact of climate change on the African predator. With an acceleration of 0-100 kph (62 mph) in three seconds the African predator is about […]

Large iceberg breaks free from glacier in southern Chile

MAGALLANES, Chile (Reuters) — A large iceberg broke off from the Grey glacier in southern Chile, authorities said on Tuesday (November 28), adding that the cause of the rupture was unclear. Chile’s CONAF forestry service shared photos on social media of the enormous block of blue-white ice, which measured 350 meters (1,148 feet) long by 380 meters (1,247 feet) wide, as it floated free in waters of a glacial lagoon near the southern tip of […]

Indonesia: the world’s volcanic hotspot

JAKARTA, Indonesia (AFP) — Indonesia, where more than 40,000 people have been evacuated over fears of an imminent volcanic eruption at Mount Agung on Bali, is the world’s most volcanic area. The Southeast Asian archipelago of more than 17,000 islands and islets — and nearly 130 active volcanoes — is situated on the Pacific “Ring of Fire”, a vast zone of geological instability where the collision of tectonic plates causes frequent quakes and major volcanic […]
