Fire Earth

Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Australia: World’s Smallest Continental Dust Bowl

Another Dust Storm Sweeps North Central Australia

Another dust storm blew across Australia’s Northern Territory and Queensland on October 26, 2009, as the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite passed overhead. This true-color image shows the dust plume traveling eastward. In Northern Territory, the dust passes south of Newcastle Waters. In Queensland, the plume skirts a cluster of fires—roughly marked by red outlines—that send their smoke plumes northward.

Washington: Thousands of Tons of Topsoil Lost in Dust Storm

Dust Plagues: An Increasingly Significant Threat as a Collapse Mechanism

Dust Storm in Eastern Washington [NASA Earth Observatory]

DUST wash_TMO_2009277
Visibility dropped to zero in parts of eastern Washington on October 4, 2009, as a large dust storm blew through. This image of the storm was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite shortly after noon (Pacific Daylight Time). According to local news, the storm brought strong winds gusting to 43 miles per hour in places that propelled the dust across the southeast corner of the state. After numerous multi-vehicle accidents, sections of Interstate 90 near the town of Moses Lake and several local roads had to be closed for several hours.

The dust storm persisted for several hours and was still visible when Aqua MODIS flew over the region at 2:00 p.m. local time. The Terra MODIS image shown here is available in multiple resolutions from the MODIS Rapid Response System.

A thick, rippling plume of dust runs northeast to southwest through the center of the image. Dust stretches as far south as the cities of Pasco and Kennewick, which sit on opposite banks of the Columbia River. In the north, the dust seems to rise primarily from the pale golden squares of fields farmed using dryland agriculture, a common practice in arid eastern Washington. The dryland fields are larger and less colorful than the bright green and gold fields of irrigated agriculture near the Columbia and Snake Rivers in the center of the image.

Dryland farmers rely entirely on rainfall to sustain their crops, and as a result, do many things to preserve moisture in the soil. Some of these practices—leaving a field fallow after harvest to allow water to build in the soil for a year or covering the field with dry soil to prevent underlying moisture from evaporating—make dryland agriculture very prone to dust storms. These fields are likely either fallow or newly planted, probably with winter wheat, a common dryland crop in eastern Washington.

    Australia: What can burn, will!

    Posted by feww on September 29, 2009

    ashes to ashes …

    Australia fires and dust_AMO_2009270
    The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this image on the afternoon of September 27, 2009. Red dots and plumes of smoke mark the locations of dozens of fires burning throughout Queensland. The large image provided above has a resolution of 250 meters per pixel, MODIS’ maximum resolution. The image is available in additional resolutions from the MODIS Rapid Response System.

    The thick wall of dust that blew across Australia on September 26, 2009, hung in a slightly thinner veil over the Coral Sea on September 27. Ripples and waves shape the dust in reflection of turbulence in the air. The dust will gradually settle over the ocean, where it will provide a source of iron to phytoplankton, microscopic plant-like organisms that grow in sunlit surface water. The iron acts as fertilizer, making it possible for large phytoplankton blooms to develop. While phytoplankton are an important source of food for marine life, too much phytoplankton can rob the ocean of oxygen, creating dead zones. It is certain that ocean biologists will watch closely to see if and how the immense dust storms of September 2009 will affect Australia’s Great Barrier Reef, visible as blue-green dots in the top center of the image.

    Australia: Uranium Dust Threat Real?

    Posted by feww on September 28, 2009

    Future storms may contain radioactive dust, if mine proposal goes ahead—Environmentalist

    An Australian documentary maker says that  future dust storms in the country may contain radioactive materials, if the mining company BHP Billiton’s proposal to turn a uranium mine into an open-cut mine goes ahead.

    David Bradbury, a renowned filmmaker and environmental activist, who has made four documentaries on nuclear issues, says an  environmental impact study suggest that about 70 million tons of radioactive tailing would be deposited at South Australia’s Olympic Dam uranium mine grounds each year.

    The tailings are contaminated with alpha radiation, he says, which is proven to be carcinogenic to all animals, including humans.

    “My grave concern is that with the open-cut mine expansion that BHP Billiton wants permission from state and federal governments to go ahead with, that the radioactive tailings left behind will blow over the eastern coast centres of the most populated cities of Australia,” he said.

    Bradbury concerns came amid last Wednesday  worst ever dust storm in the Sydney and Brisbane areas as  red dust blown in from the outback shrouded the region, causing problems for people, especially those with asthma, and others with heart and lung conditions.

    “[Since] the dust storms…  originated from Woomera, and which is right next door to the Olympic Dam mine at Roxby Downs, these [storms] could blow those tailings across the face of Australia,” said Bradbury.

    However, Australian scientists are playing down fears, assuring the public that there is nothing to worry about [sic.]

    Barry Noller an Associate Professor from the University of Queensland, whose research projects include Risk Assessment of Mined Land,  was quoted as saying that most of the particles from the uranium mines in the outback are simply too heavy to be carried by the wind over long distances.

    “In a big dust storm, the dust is not going to come from one isolated site, it is going to be mixed in with dust from a [wide] area and diluted considerably,” said Noller.

    FEWW Comments:

    Come again? What if the storms were stronger and blew more sand more frequently, say, twice more, perhaps five times, or ten time as much every year? The recent atmospheric trends and new patterns set by climate change certainly suggest such extreme scenarios as highly probable!

    That’s the most ridiculous comment an Associate Professor could possibly make, even one from the University of Queensland, without quantifying the extent of the problem. The stronger the storms the more dust they carry over populated areas, and with it goes more of the heavier particles.

    Here’s what the Aussies, even their corporate media, should demand to know:

    How much stronger must the storms be, and how frequently must they below before they pose,  (i) some risk, (ii) significant risk to the public health, threatening human and animal well being?

    Should this professor make similarly stupid, biased and unqualified remarks again, the Moderators will have to investigate his role and function as a government scientist with regulatory bias.
