Earth Changes
Take a few signs from last week alone.
Australia's pre-eminent academic geologist, Prof Ian Plimer, published Heaven and Earth, challenging the gospel that the world is warming dangerously and that human-caused gases are to blame. In fact, says Plimer, what warming we saw until a decade ago was not unusual, not dangerous and most likely caused mainly by solar activity. What's more, temperatures now seem to be falling.
The quake struck around 5:25 a.m. today and could be felt all around Birmingham.
The quake's epicenter was 7 miles north of Centreville near the intersection of highways 5 and 219. The depth was 8.8 miles below the earth's surface.
The earthquake was 25 miles southwest of Alabaster, 30 miles east southeast of Tuscaloosa and 40 miles south southwest of Birmingham.
In a presentation to the Society for General Microbiology meeting at Harrogate International Centre March 30, Dr Heike Schmitt from the University of Utrecht, the Netherlands described how antibiotics passed from the animals in manure that was then spread on farmland. Although higher organisms, such as earthworms, would only be affected at unrealistic concentrations of antibiotics, changes in soil bacterial communities have been found repeatedly using molecular microbiological techniques.
After all, it's become nearly impossible to open a magazine, unfold a newspaper or turn on the television without being scolded about the selfishness of your energy consumption and the damage your unworthy existence does to the planet. And yet, Friday's Rasmussen found that forty-eight percent of all likely voters attribute climate change to long-term planetary trends, not their so-called carbon-footprint. That's up 4% in less than three months.
The gospel of high-tech genetically modified (GM) crops is not sounding quite so sweet in the land of the converted. A new pest, the evil pigweed, is hitting headlines and chomping its way across Sun Belt states, threatening to transform cotton and soybean plots into weed battlefields.
In late 2004, "superweeds" that resisted Monsanto's iconic "Roundup" herbicide, popped up in GM crops in the county of Macon, Georgia. Monsanto, the US multinational biotech corporation, is the world's leading producer of Roundup, as well as genetically engineered seeds. Company figures show that nine out of 10 US farmers produce Roundup Ready seeds for their soybean crops.
Corn and soybeans modified to resist insects and the herbicide glyphosate haven't been proven to boost yields, the Cambridge, Massachusetts-based group says in a 44-page report. The modified plants have increased the number of glyphosate-resistant weeds that compete for soil nutrients and moisture, reducing production, the group says.
There was no threat of tsunami from the quake at 4:19 a.m. (1919 GMT). It centred in the remote and sparsely populated Kuril Islands northeast of Hokkaido, the Japan Meteorological Agency said on its website (www.jma.go.jp).
No tsunami alert was issued.
'Tremors are felt in the area but not significant ones. There's no report of damage,' agency official Suharjono told AFP.
Zinchenko's vessel, the Spirit of Enderby, was commissioned in January last year to retrace the steps of the great Antarctic explorer Ernest Shackleton, marking the century of his Nimrod expedition of 1907-09.
Spirit of Enderby was blocked by a wall of pack ice at the entrance to the Ross Sea, about 400km short of Shackleton's base hut at Cape Royds. Zinchenko says it was the first time in 15 years that vessels were unable to penetrate the Ross Sea in January. The experience was consistent with his impression that pack ice is expanding, not contracting, as would be expected in a rapidly warming world. "I see just more and more ice, not less ice."
Two of the Arctic ice sites show April 16 ice at recent record levels. The Japanese site IJIS has a seven year April record going back to 2003, and reports 2009 levels at the highest extent on record for the date: 13,649,219 km2.
The Danish Meteorological Institute has a five year database, and also shows April 16 ice extent as the highest in their short record.
