Hubris in climate change

Hubris in global climate science scares me. As a scientist, I often carry a British coin that bears Isaac Newton's statement "standing on the shoulders of giants" as a reminder of humility. I try to remember that most of what I know and understand comes from the work of others before me and a larger reservoir of existing knowledge. Considering this, and hoping knowledge leads to wisdom, it becomes very important to seek wisdom in the climate-change discussion.

Consider geology. From the recent G8 discussions, it is apparent that we are intent, as humans, to mitigate global climate change. During a recent climate-change forum, I heard a distinguished International Panel on Climate Change scientist state that "113 distinguished scientists" agreed that the earth is warming. This statement was made, rather emphatically, to a room filled with hundreds of geologists who did not react at all. The fact is that geoscientists worldwide, and possibly many archaeologists, would agree.

Bush Fires Blaze Around Southern Europe

Bush fires raged across swathes of southern Europe Friday, with a prolonged spell of hot weather turning woodland around the Mediterranean coastline tinder dry. Hundreds of fires in Spain, France, Italy and Greece have killed at least seven people this week, destroying thousands of hectares of forest and gutting dozens of homes.

Spain has been the worst hit and authorities said Friday thousands of villagers have had to be evacuated to escape wildfires that have killed five firefighters. Thousands of police and soldiers had been drafted in to help combat seven serious fires in the south and east of Spain.

Indonesia: Drought severely hits rice paddies

Months before another El Ni*o, expected to deepen drought around the country, hundreds of rice paddies have already produced failed harvests. Data from the Agriculture Ministry showed that 26,388 hectares of rice paddies suffered from drought in the April to June period due to water shortages.

"However, the figure is still far lower than it was in the 2003 to 2007 period when an average of 82,472 hectares of rice paddies suffered from drought each year," Ati Wasiati, director for the protection of food crops at the Agriculture Ministry told The Jakarta Post on Thursday.

She remained optimistic about the target to plant rice in 5 million hectares up until September despite the expected impacts of the El Ni*o phenomenon.

Nature not man responsible for recent global warming

Three Australasian researchers have shown that natural forces are the dominant influence on climate, in a study just published in the highly-regarded Journal of Geophysical Research. According to this study little or none of the late 20th century global warming and cooling can be attributed to human activity.

The research, by Chris de Freitas, a climate scientist at the University of Auckland in New Zealand, John McLean (Melbourne) and Bob Carter (James Cook University), finds that the El Niño-Southern Oscillation (ENSO) is a key indicator of global atmospheric temperatures seven months later. As an additional influence, intermittent volcanic activity injects cooling aerosols into the atmosphere and produces significant cooling.

Alien-Wasp Swarms Devouring Birds, Bugs in Hawaii

Wasps

Attacking from nests as big as pickup-truck beds, invasive western yellowjacket wasps in Hawaii are munching their way through an "astonishing diversity" of creatures, from caterpillars to pheasants, a new study says.

Adult yellowjackets consume only nectar. But they kill or scavenge prey to deliver needed protein to their growing broods.

"They basically just carry it in their mandibles - you see them flying with their balls of meat," said lead study author Erin Wilson, who just finished her Ph.D. at the University of California, San Diego.

In their native habitat in the western U.S., the wasps die off in winter. But in Hawaii the wasps survive the winter, possibly due to mild year-round temperatures or subtle genetic changes.

5.6 Earthquake Jolts Tibet

An earthquake measuring 5.6 on the Richter scale hit Nyima county in Nagqu prefecture, southwestern China's Tibet Autonomous Region, at 11:11 a.m. on Friday, according to the national seismological network.

No casualties have yet been reported.

At a depth of 33 kilometers, the quake struck on the line between Nyima and Coqen county of Nagri prefecture, according to the regional seismological bureau of Tibet.

The epicenter was located at Ceri township in Coqen county, where telecommunication links were cut, the regional bureau said.

Sogrin, deputy head of the bureau, said the quake caused cracks in some houses made of sun-dried mud bricks at the county seat of Coqen, but no tremor was felt at the county seat of Nyima.

West of the United States faces water 'catastrophe'

A new study projects that all reservoirs along the Colorado River -- which provide water for 27 million people in seven Western states, including Utah -- could dry up by 2057 because of climate change and overuse.

If warming led to a 10 percent reduction in the river's flow, it would create a 25 percent chance of depletion, according to the University of Colorado research released this week. Warming resulting in a 20 percent reduction would raise the chance of depletion to 50 percent, the study found.

"In the short term, the risk is relatively low," said Balaji Rajagopalan, associate professor of civil environmental and architectural engineering at the university and lead author on the study, which was accepted for publication by the American Geophysical Union.

Study Finds Chimps Die From Simian AIDS, Dispelling Widely Held Belief

For the first time, scientists have shown that chimpanzees in the wild become sick and die from the simian version of AIDS.

The finding upsets a widely held scientific belief that chimpanzees, the closest relatives to humans, can get the virus that causes simian AIDS but without harm.

It also suggests that an outbreak of AIDS is contributing to the declining chimpanzee population in Africa, said the leader of the research team, Dr. Beatrice Hahn of the University of Alabama at Birmingham.

Met Office winter 'forecast' 2009-10 attacked as 'reckless misleading nonsense

"It should be ignored absolutely. The opposite to whatever the Met Office says in long range has been what happened for the last three years!" Piers Corbyn, astrophysicist of WeatherAction said today, 23 July:

"The Met Office long range forecast attempts at seasonal and world developments totally failed to predict ANY of the 5 notable weather developments since 2007. They predicted the opposite to what occurred for the wet summers 2007, 2008, and 2009, the icy snowy winter 2008/09, and world temperature decline over recent years. On the other hand our WeatherAction Solar Weather Technique predicted all these major situations correctly and did it ahead of the Met Office prognoses.

Their score of zero out of five is lamentable. It could not be worse. They should stop issuing these reckless 'forecasts' which only serve to mislead the public, commerce and emergency authorities and cause unnecessary misery, danger and possible death.

Their forecast for a mild winter in 08/09 disarmed the emergency services and Councils and led directly to the UK running out of road salt, transport chaos and extra road accidents when the snow deluges predicted by us at WeatherAction hit Britain and Ireland. The Met Office stupidity cost the economy billions of pounds. "The recent heavy rains and weather prospects spell failure for the Met Office forecast of a 'barbecue summer' which we advised our own forecast users would fail. For how much longer will government, 'opposition' and much of commerce continue to follow failed methodology which is without scientific basis?

Pacific Northwest Snow Pack - the True Story

Washington Governor Gregoire recently sent a letter to the Washington House delegation in which she stated that the snow pack has declined 20% over the past 30 years: "Last month, a study released by the University of Washington shows we've already lost 20% of our snow pack over the last 30 years."

Actual snow pack numbers show a 22% INCREASE in snow pack over the past 33 years across the Washington and Oregon Cascade Mountains.
