Radioactive Spike

Tiny amounts of radioactive iodine were detected in the air along Norway’s border with Russia following a deadly explosion that occurred during a secret rocket engine test in northern Russia’s Arkhangelsk region.

Russia’s meteorological agency said radiation levels in the city of Severodvinsk spiked by up to 16 times following the nearby blast.

U.S. experts believe Russia was testing a nuclear-powered cruise missile when the explosion occurred, killing five research staff and military personnel.

Four of the five stations in Russia that scan for radionuclide particles in the air for the Comprehensive Nuclear Test-Ban Treaty Organization went silent for days following the blast.

Rain Tree

A team of Chinese and international researchers say they have developed an inexpensive solar-powered “tree” that desalts enough water each day from the sea to provide clean drinking water for at least three people per “leaf.”

The scientists say roots made of cotton fibers soak up water and send it up a metal stem, where leaves made of black-carbon paper convert sunlight into heat.

After the water is heated by the leaves to nearly 122 degrees Fahrenheit, the resulting water vapor is cooled and condensed back as fresh water.

The technology could be deployed in small communities or on remote islands to help ease water shortages.

Wildlife

Wildlife summit votes down plan to allow sale of huge ivory stockpile

An attempt to allow a huge sale of stockpiled elephant ivory has been defeated at an international wildlife conference. The rancorous debate exposed deep divisions between African nations with opposing views on elephant conservation.

About 50 elephants are still being poached every day to supply ivory traffickers and all countries agree the world’s largest land animal needs greater protection. But southern African nations, which have some of the largest elephant populations, want to allow more legal sales of ivory to fund conservation and community development. But 32 other African nations argue all trade in elephants must end, including the trophy hunting legal in some states.

The new sale proposal was comprehensively voted down by 101 votes to 23.

Giraffes to be protected as endangered species for the first time

The Cites nations did give new protection to the giraffe by voting to end the unregulated international trade in the animal’s parts.

There are fewer giraffes alive than elephants and their population has plunged by 40% since 1985 to just 97,500. However, this debate also exposed the same north-south divide in the continent.

The proposal was passed when countries voted by 106 to 21.

New Mexico proposes ban on wildlife trapping near cities

New restrictions on wildlife foot traps and wire snares were proposed Thursday by regulators seeking to resolve conflicts over trapping traditions and evolving attitudes about animal suffering.

The New Mexico Game and Fish agency outlined a proposal to ban traps and snares on select tracts of public lands outside of Albuquerque, Santa Fe, Las Cruces and Taos, along with a half-mile no-trapping buffer at officially recognized hiking trailheads.

The proposal includes mountainous areas east of Albuquerque that are popular for outdoor recreation, along with swaths of national forest along mountain highways leading to ski areas near Santa Fe and Taos. Trappers would be required to attend training. Also, design specifications for traps and snares are being suggested to reduce the risk of animals being maimed by snares and to ensure they don’t walk away with traps attached.

Environment

Global Temperature Extremes

The week’s hottest temperature was 121 degrees Fahrenheit (49.4 degrees Celsius) in Basra, Iraq.

The week’s coldest temperature was minus 107.0 degrees Fahrenheit (minus 77.2 degrees Celsius) at Russia’s Vostok base, Antarctica.

Temperatures were tabulated from the more than 10,000 worldwide synoptic weather stations. The United Nations World Meteorological Organization sets the standards for weather observations, and provides a global telecommunications circuit for data distribution.

Wildfires

Wildfires – Australia

Firefighters are working to contain a bushfire north of Brisbane but have warned they may not be able to protect every property in the semi-rural area and conditions could get worse.

Meanwhile Pilots flying over Bribie Island’s northwestern beaches were met by a heartbreaking scene this afternoon. Numbers of dead kangaroos were spotted from the air. They had been killed fleeing the bushfires. The bushfires at Bribie Island engulfed campsites on Wednesday and Thursday, with water bombers deployed from helicopters top douse the remaining flames today.

Wildfires – Bolivia

Bolivian authorities warned this week that 70% of the department of Santa Cruz — where more than a quarter of the country’s population lives — is under “extreme risk” from forest fires.

According to the government, nearly 500,000 hectares of forest have now been turned into ashes.

According to Brazil’s space research centre (INPE), 72,843 fires have hit the country’s side of the Amazon — an 83% increase on last year and the highest number registered since records began in 2013. The smokes from the wildfires on Wednesday caused an hour-long blackout in Sao Paulo, located 2,700 kms away.

Greenpeace has blamed the record number of wildfires in the Brazilian Amazon on deforestation. It also warned that it could have severe meteorological consequences for the region but also for the globe.

Disease

Anthrax – Armenia

Armenia health ministry officials reported three additional human cutaneous anthrax cases in the village of Geghhovit, Gegharkunik Province, bringing the total cases to eight. All the patients are receiving treatment, the ministry said. The Food Safety Inspectorate has reported the outbreak has been linked to a single unvaccinated, diseased cow.

West Nile Virus – Las Vegas, USA

In the Las Vegas/Clark County area, health officials have declared an outbreak of West Nile virus (WNV) after receiving reports of 28 cases of the disease in humans – the highest case count in a season since the virus was first detected in the state in 2004.

African Swine Fever – South Africa

Gauteng officials have warned farmers of a new outbreak of African swine fever, after it was detected in an informal set up in the Swaniesville area. A group of about five pig owners were affected. There are around 1 000 pigs in the area and the culling process was still pending.
