Farmers have spoken out about worrying levels of lamb and calf losses on their farms.

It follows reports from scannersthat they are seeing unusually high numbers of barren animals, failed pregnancies and dead foetuses on some farms this season.

An Oxfordshire beef producer scanned 80 suckler cows two weeks ago and was shocked to discover that 43 were in calf and 37 were empty.

"We're a closed herd and we have never had this problem before," he said. "It was painful doing the PDs (pregnancy diagnostic tests) - it felt like having your teeth pulled out with no anaesthetic."

The farmer is not putting the losses down to poor nutrition as, despite this year's bad weather, there has been plenty of grass.

Authorities are warning north Queensland residents of potential flooding after heavy rains from a former cyclone continue to fall.

Emergency Management Queensland (EMQ) says the downpours are expected to continue for several days as far south as Rockhampton.

EMQ Assistant Director General Bruce Grady says with the state's far north already saturated, residents further south needed to start stocking emergency supplies in preparation.

That really depends on how you define pollutant. For the purposes of this column, let's put aside greenhouse gases and the eventual effects of climate change and focus on more tangible pollutants, starting with the ones that make their way from industry into communities nearby. A nonprofit group called the Blacksmith Institute reports on these at the end of every year.

The group's most recent study examined key pollutants at toxic sites in 49 countries and concluded that lead pollution from mining, smelting, and recycling (the latter often done from car batteries) accounted for the most pervasive risk to human health in 2012. The group estimates that lead affects at least 16 million people around the world.

Excessive lead exposure can lead to kidney problems, reduced IQ or learning disabilities, growth impairments, and nerve disorders. Acute poisoning may result in seizures and death. The only upside of environmental lead is that unlike, say, emissions of CO2, it may be on the wane.

Many countries have already phased out leaded gasoline, and others are soon to follow. Old cathode ray tubes were full of lead, but we're moving away from those as well.

David Attenborough: 'Humans are a plague on Earth'

Sir Attenborough said commentary from presenters like himself are becoming less necessary as camera work is able to tell a story.

The television presenter said that humans are threatening their own existence and that of other species by using up the world's resources.

He said the only way to save the planet from famine and species extinction is to limit human population growth.

"We are a plague on the Earth. It's coming home to roost over the next 50 years or so. It's not just climate change; it's sheer space, places to grow food for this enormous horde. Either we limit our population growth or the natural world will do it for us, and the natural world is doing it for us right now," he told the Radio Times.

Sir David, who is a patron of the Optimum Population Trust, has spoken out before about the "frightening explosion in human numbers" and the need for investment in sex education and other voluntary means of limiting population in developing countries.

"We keep putting on programmes about famine in Ethiopia; that's what's happening. Too many people there. They can't support themselves - and it's not an inhuman thing to say. It's the case. Until humanity manages to sort itself out and get a coordinated view about the planet, it's going to get worse and worse."

10 volcanic earthquakes rattle Philippines's Taal Volcano: Activity increases in the last 24 hours


The Extinction Protocol

The Philippine Institute of Volcanology and Seismology said Tuesday the seismic activity of Taal Volcano in Batangas province has increased in the past 24 hours. Phivolcs Director Renato Solidum, Jr. said the agency has recorded 10 volcanic quakes from 7 a.m. Monday to 7 a.m. Tuesday. But Solidum said no steaming has been observed in the past 24 hours and water temperature at the main crater lake decreased from 31.7 to 30.9 degrees Celsius.

The Phivolcs chief noted the volcano's Alert Level 1 will be maintained as "10 volcanic quakes are still appropriate for a volcano that is under abnormal level." He said that a volcano under Alert Level 1 means that abnormal volcanic activities are observed, though a hazardous eruption is not imminent. Since January 18, Solidum said Taal Volcano was relatively calm, with its seismic network recording "zero to eight" volcanic earthquakes in a day. - MST

Strong 5.8 magnitude earthquake kills 1 in Indonesia


The Extinction Protocol
Tue, 22 Jan 2013 07:50 UTC

Indonesia's meteorology and geophysics agency put the preliminary magnitude at 6.0 (5.9 USGS) and said the inland quake caused no tsunami. It was centered southwest of the city of Banda Aceh and 10 miles (6 kilometers) beneath the earth's crust, according to the U.S. Geological Survey. The quake hit about 5:22 a.m. (22:22 GMT Monday), rattling people awake in towns and villages across the Sumatra Island's northern tip. A magnitude-4.7 aftershock quake followed a few minutes later. Sarjani Abdullah, the district head of Pidie, said a 9-year-old girl was found dead in the ruins of her home. At least seven other people, including a 3-year-old, suffered cuts and broken bones.

Aceh province's disaster mitigation agency said at least 30 houses and a mosque were ruined in Pidie Jaya district and hundreds of people were moved to temporary shelters as authorities surveyed the extent of the damage. Some electricity poles were knocked down in Tangse village, crashing into homes and causing blackouts. "It's scared us. ... We are still traumatized by the earthquake. My wife was screaming, my children crying," said Masriadi, a Tangse resident. Fearing aftershocks, many people refused to go back inside for hours. Indonesia straddles a series of fault lines that makes the vast archipelago prone to volcanic and seismic activity. - ABC

Strong 5.8 magnitude earthquake strikes off east coast of Brazil - quake from a previously unknown fault?


The Extinction Protocol
Tue, 22 Jan 2013 07:46 UTC

A rather shallow 5.8 magnitude earthquake struck the ocean floor just off the coast of Brazil, south of the popular tourist destination of Natal. The eastern coast of Brazil is relatively free from faults and is not located on the border of any major tectonic plates. So this earthquake is quite unusual. If we look at the seismic hazard map of Brazil (below), it's clear to see that most of Brazil's seismic hazards lie in the western part of the country. See local quake map of Brazil.

Unusual: Is this quake from a previously unknown fault this close to the shoreline or might other factors be at work here...like the area of growing weakness of the planet's magnetic field in the South Atlantic Anomaly? Natal is virtually near the epicenter of the SAA. The South Atlantic Anomaly (SAA) is an area where the Earth's inner Van Allen radiation belt comes closest to the Earth's surface dipping down to an altitude of 200km (124mi). This leads to an increased flux of energetic particles in this region and exposes orbiting satellites to higher than usual levels of radiation. The effect is caused by the non-concentricity of the Earth and its magnetic dipole, and the SAA is the near-Earth region where the Earth's magnetic field is weakest. -The Extinction Protocol

Eruptive activity on the rise at two sites on Big Island's Kilauea volcano


The Extinction Protocol
Tue, 22 Jan 2013 07:42 UTC
Eruptive activity at the Big Island's Kilauea volcano is picking up at the Pu u Oo vent and Halemaumau Crater. At the Pu u Oo vent, situated in the volcano's East Rift Zone, lava flows are sporadically spilling onto the east flank of the vent. The volume of lava streaming to ocean entry is increasing slightly, with small entry points now spread along the coastline near Kupapu Point on both sides of Hawaii Volcanoes National Park. The current ocean-entry flow has been under way since mid-November. This month marks the 30th anniversary of Kilauea volcano's ongoing East Rift Zone eruption. During its first three years, spectacular lava fountains spewed from the Pu u Oo vent.
Image
Since then, nearly continuous flow has built a vast plain of slow-moving pahoe hoe lava stretching from the volcano's rift zone to the Big Island's shoreline. Also, in recent months, at Kilauea volcano's summit caldera, the lava lake swirling in Halemaumau Crater has been rising to record levels. Since March 19, 2008, when an explosive eruption formed the lava lake, its surface level has remained mostly below the inner ledge (about 100 feet below the floor of Halemaumau Crater).

Eruptions of Papua New Guinea's Mt Tavurvur have forced some flights in and out of New Britain to be cancelled. The ash and vapor blowing from the volcano affected flights to Tokua Airport. Air Niugini says the flight suspension came into effect on Monday and will continue for an indefinite period. Newspaper reports say low to loud roaring and rumbling noises were heard on Sunday night when the volcano erupted. Tavurvur is an active volcano that lies near Rabaul in Papua New Guinea. It is a sub-vent of the Rabaul caldera and lies on the eastern rim of the larger feature. The volcano is most well known for its devastating eruptions over Rabaul. Mt Tavurvur is the most well known volcano in Rabaul caldera, and has erupted as recently as January 2009. The last time the volcano erupted was in 2011. - Radio New Zealand Wikipedia
