India – The heaviest rainfall in over a century caused massive flooding across Tamil Nadu, driving thousands from their homes, shutting auto factories and paralysing the airport in capital Chennai. The national weather office predicted three more days of torrential downpours in the southern state of nearly 70 million people. No deaths were reported and the extent of damage would only become clear when the floodwaters recede. Air and rail traffic has ground to a halt.

South Africa – A heat wave has claimed the lives of two people in a shopping mall in Cape Town. Two people died in Khayelitsha Shopping Mall as the mercury reached 34°C.


Wildfires – Brazil

Wildfires are raging through the Brazilian Amazon, destroying vast areas of forest on the eastern fringes of the “earth’s lungs”. The outbreak of the fire coincides with the start of the international COP21 climate summit in Paris and threatens one of the last un-contacted peoples on earth.

The fires are reportedly being started by illegal loggers, in retaliation for tribal people’s efforts to defend their territories and keep the invaders out. They threaten one of the few remaining areas of pre-Amazon forest in Brazil, the last environment of its type in the world.

This forest is home to the Awá tribe, one of the most vulnerable peoples on the planet. The Awá depend completely on the land for their survival.

In October, fires destroyed almost half of a nearby indigenous territory known as Arariboia, also home to uncontacted Awá. It is not known whether the two incidents are connected, or if they indicate that loggers are adopting a new strategy to claim land from tribal people.

Survival International, the global movement for tribal peoples’ rights, is calling on the Brazilian government to put out the fire, protect the Awá’s land and save them from extinction.


Roundup of Global Volcanic Activity

Zhupanovsky (Kamchatka, Russia): After its re-awakening 3 days ago, a strong explosion occurred from the volcano yesterday at 13:50 local time and produced a plume that rose to approx. 30,000 ft (9 km) altitude and drifted SE. It was clearly visible even from the capital Petropavlovsk. Whether it was a phreatic (no magma involved), or phreato-magmatic or even magmatic eruption remains unclear at the moment. The aviation colour code of the volcano was raised to orange.

Awu (North Sulawesi & Sangihe Islands): Last week, PVMBG raised the alert level of Indonesia’s northernmost known active volcano a notch, as small signs of new unrest had been detected recently: mostly, this is an increase in shallow seismic activity since the summer and more pronounced since the middle of November. On the other hand, gas measurements still show low values for SO2 and CO2, typical magmatic gasses of deeper origin. An eruption is currently not expected in the near future, but increased vigilance about the volcano is in place.

Colima (Western Mexico): Intermittent explosions of small to moderate, sometimes large size continue to occur at the volcano. Attached image from 25 Nov shows a moderately large event.

Santiaguito (Guatemala): A phase of elevated activity has started at the volcano since 29 November. The largest event so far occurred this morning at 07:07 local time, when a strong explosion produced an ash plume that rose approx. 2-3 km and (probably) a small pyroclastic flow. Ash fall occurred in nearby villages and towns including San Marcos Palajunoj, and Finca La Florida. During the preceding days, several smaller, but significantly larger than average explosions occurred from the Caliente lava dome, which on average had only been producing 2-3 small explosions per day before.

Fuego (Guatemala): The 12th paroxysmal eruptive phase of the volcano during 2015 has ended over night. During its peak yesterday, lava fountaining from two summit vents fed 5 lava flows on the volcano’s western, southern and eastern sides reaching lengths of 1.5-3 km. According to INSIVUMEH, this episode was the largest of the 12 eruptions in 2015 by lava output volume, but remarkably only generated smaller pyroclastic flows headed towards barranca Honda.

Momotombo (Nicaragua): A series of at least 4 small explosions occurred at the volcano this morning, at 07:49, 08:17, 08:42, and 08:55 local time. The eruptions, in particular the last and largest one, produced steam and ash plumes that rose up to approx. 1 km from the summit. Light ash fall was observed in the community of El Papalonal and near the Momotombo geothermal plant to the SW of the volcano.

Turrialba (Costa Rica): A small eruption occurred from the volcano’s western crater this morning at 06:38 local time.

Copahue (Chile/Argentina): Activity at the volcano continues to slowly increase. Over the past days, continuous explosive activity at the summit vent has been producing a plume of dark ash that reached 1-2 km height and drifted into easterly directions. Glow is often visible at the crater during the night.

Oman – A landslide in Tawi Al Nisf in Samayil province in Oman has claimed the life of a worker on Monday afternoon when a truck was hit by the debris that crashed down from a mountainside.

Sumatra, Indonesia – Torrential rain has caused landslides in parts of West and North Sumatra, cutting off access and disrupting economic activity. He said the heavy rain that had drenched the region in the past three days had triggered floods and landslides in a number of locations in the regency. At least 500 homes were engulfed by over 50 centimetres of floodwater and eight homes were reportedly damaged by a landslide on Sunday morning.


Angry Birds? Seagulls Implicated in Baby-Whale Deaths

At least 626 right whale calves died off Península Valdés off the coast of Argentina between 2003 and 2014, and seagulls may have played a role in their deaths, a new study suggests.

While you might think of seagulls as mere pests — squawking masses of feathers that loom over the beach, waiting for dropped potato chips — these birds pose a serious threat to several species of animals, including the southern right whale (Eubalaena australis).

Gull harassment of right whales off Argentina’s Península Valdés has been observed since the 1970s. That’s when kelp gulls (Larus dominicanus) were first seen pecking the skin and blubber off the backs of adult female whales that use this sheltered spot off Argentina’s Atlantic coast as a calving ground. Since then, researchers from universities and conservation institutions in Argentina and the United States have monitored the gulls’ behaviour. Their most recent observations of the gulls’ continued harassment of right whales — and this behaviour’s potential link to soaring calf deaths — were published last month (Oct. 21) in the journal PLOS ONE.

The kelp gulls’ feisty feeding behaviour has gotten progressively worse since it was first documented.

However, the relationship between gulls and right whales started innocently enough. The birds would hover over the giant mammals as they breached, or jumped out of the water to breathe. When breaching, some of the whale’s dead skin is sloughed off, floating to the surface and providing a tasty snack for gulls, she said. But several decades ago, the gulls adapted this behaviour to include pecking at the whales themselves as they breached.

A graduate student [Peter Thomas] observing the whales noticed that the seagulls had begun to land on top of the mothers and peck at them, making a hole. Then, in subsequent attacks throughout the season, they’d make the hole larger.

These holes, or lesions, grew to be large ovals, sometimes stretching all the way down the centre of the whales’ giant backs. (Female right whales grow to be about 49 feet, or 15 meters, long, from head to tail.) But starting in the 1990s, something changed: Fed-up mother whales started defending themselves against the birds’ attacks by keeping their backs underwater when they breached. This was good news for mother right whales, but bad news for their babies. The zero- to three-month-old calves don’t know how to keep their backs underwater. Their backs are too small to arch, and now, the gulls’ primary targets are the newborn calves.

In the 1980s, when mother whales were still the gulls’ primary targets, the average right whale calf had just two small lesions on its back. But by the 2000s, the average number of lesions on the calves’ backs had grown to 20. One calf that had been repeatedly pecked at by the birds had lesions covering 19 percent of its back, the study found.

The increase in lesions on baby whales in recent years is linked not only to a decrease in lesions on mother whales but also to an increase in the frequency of gull attacks, according to the study, which states that such attacks have increased “dramatically” over the past three decades. Mother-calf pairs may spend 20 percent of daylight hours dealing with such attacks

The study authors also pointed to recent research about the horrid eating habits of kelp gulls in another part of the world. In Namibia, seagulls peck out the eyes of juvenile Cape fur seals, making them highly vulnerable to repeat attacks in which the gulls consume the baby seals’ skin and blubber. This research suggests that attacks by kelp gulls could potentially lead to the deaths of “young marine mammals” that can’t easily recover from injuries caused by the gulls.

Whether the deaths of the young whales can be fully attributed to the behaviour of the gulls remains uncertain, however the constant stress caused by the gulls and the gaping wounds they inflict might also inhibit a calf’s ability to fend off other threats, like dehydration, parasitic infection or even hunger.

Japan whaling fleet sets to sea for hunt

Japan’s whaling fleet set out for the Antarctic on Tuesday to resume a hunt for the mammals after a year-long hiatus, prompting criticism from Australia as well as key ally, the United States.

Japan aims to take more than 300 whales before the hunt ends next year and nearly 4,000 over the next 12 years as part of a scientific programme to research the whales.

The International Court of Justice (ICJ) ruled last year that Japan’s whaling in the Southern Ocean should stop and an International Whaling Commission (IWC) panel said in April that Japan had yet to demonstrate a need for killing whales.

But Tokyo retooled its plan for the 2015/16 season to cut the number of minke whales it intends to take to 333, down by two-thirds from previous hunts.

Japan, which has long maintained that most whale species are not endangered and that eating whale is part of its food culture, began what it calls “scientific whaling” in 1987, a year after an international whaling moratorium took effect.

The meat ends up on store shelves, although most Japanese no longer eat it.


‘Last-Resort’ Antibiotics Fail Against New Superbugs

Some bacteria have finally breached the last wall of humans’ antibiotic stronghold, according to a new study from China. In the study, researchers found a gene in one strain of Escherichia coli (E. coli) that protects these bacteria against one of the antibiotics considered to be a last resort. Moreover, this gene is easily transferred among microbial species, raising the possibility of multiple epidemics that doctors would be unable to treat.

When bacteria become resistant to even the last-resort antibiotics and can share that resistance with other types of bacteria, that leaves the human population extremely vulnerable to a range of infections that would be unstoppable.

In the study, the researchers found the gene, called mcr-1, in samples of E. coli that were taken from pigs, pork products and infected people. The gene protects the bacteria against an antibiotic called colistin. Mcr-1 was most common in the samples taken from animals, suggesting that it originated in livestock, the researchers said. In China, colistin is widely administered to livestock.

Animals that are raised for people to eat are routinely given antibiotics to protect the livestock against infection, and to stimulate their growth. But the constant presence of antibiotics in the livestock diet helps drive the increasing numbers of antibiotic resistant bacteria today, researchers say.

Colistin isn’t a recent addition to the drug arsenal. It was discovered in 1947, and was used widely through the 1960s, but the drug had toxic effects on the kidneys and nervous system. Doctors mostly abandoned colistin after newer and safer antibiotics came along.

But sitting on the shelf for decades is exactly what kept colistin viable in the battle against drug-resistant bacteria. Because microbes had little exposure to colistin, they did not have much opportunity to evolve protection against it. As the list of effective antibiotics has shrunk, colistin has remained one of the last reliable lines of defense against bacterial infection.

That is, until now. In the new study, the researchers found the gene for colistin resistance in bacterial structures called plasmids, which are small circles of DNA that are easily passed from one bacterium to another, and even between different bacterial species.

Researchers have long known that the use of antibiotics, in both agriculture and in medicine, has encouraged bacteria to do what they’ve excelled at for more than 3 billion years: evolve and survive.

The new drug-resistant bacteria have not been found outside of China, the investigators said. But the researchers warned there is a strong possibility this drug-resistance gene could spread.

Right now, preventing bacterial infections with measures such as vaccinations and good hand hygiene are more vital then ever. He noted that antibiotics are useful only against bacterial infections, and that taking antibiotics when they’re not needed just gives bacteria another chance to beef up their drug-resistant defences.
