“Not inconsistent with man-made global warming” !!

January 15, 2011

Climate Science – if there is such a thing – had long ago abandoned science to become a lobby for “global warming theory”. But the “scientists” are plumbing new depths.

It has not taken long for “climate scientists” to claim that all extreme weather events (heat wave in Russia, floods in Pakistan, coldest December in 100 years , droughts in Australia and now floods in Brazil and Australia)  are all “not inconsistent with global warming” implying by some strange, convoluted logic that all these weather events (which are also consistent with history repeating itself) somehow add to the body of “evidence” which “proves” that man-made global warming is happening. There have even been crack-pot scientists with such a vested interest in the “man-made global warming” ideology  who have found it possible to blame volcanic activity and even the earthquake in Haiti on “global warming”!!!

The current strength of the La Ninã conditions are perfectly consistent with other theories based on ocean variation and the frigid winters are quite consistent with the quiet Sun (which went spotless again yesterday). All current weather is also consistent with man-made effects being totally negligible and instead being dominated by the sun’s cycles and with the oceans as the primary vehicle for transporting heat around the globe. Weather is not climate and in fact none of the “extreme” weather events  are outside the range of weather variations that have been experienced over the last 1000 years.

The floods in Brazil have claimed over 500 lives and in Australia – which is far better prepared – the death toll will likely be between 20 – 30. In Australia where a higher flood occurred in 1974 in Brisbane voices are beginning to be raised that the “global warming” lobby have actually prevented the use of dams and implementation of proposed water management policies which could have been able to better manage these regular and recurring flood conditions.

The history of floods in Brisbane is telling:

Highest annual flood peaks for Brisbane

Highest annual flood peaks for Brisbane

The floods this year in Queensland are nothing new. Why would this flood be evidence of man-made global warming but not the floods of the 1800s? In fact the history of these weather conditions in Brisbane is not inconsistent with global cooling, the coming of an ice-age or an apocalyptic end to the earth in 2012!

Any scientist who is concerned with science and not with religion, politics or defending his past conclusions would know that being “not inconsistent” with some theory carries no weight in a scientific proof – but it does sound so credible in a TV sound-bite.

But we can expect that over the next few years that every natural disaster or extreme weather event will be taken by the members of a dying religion as being “not inconsistent with” and therefore as proof of man-made global warming.

La Niña Strengthens further

October 25, 2010

The NOAA has released its annual winter outlook.

The Pacific Northwest should brace for a colder and wetter than average winter, while most of the South and Southeast will be warmer and drier than average through February 2011. A moderate to strong La Niña will be the dominant climate factor influencing weather across most of the U.S. this winter.

“La Niña is in place and will strengthen and persist through the winter months, giving us a better understanding of what to expect between December and February,” said Mike Halpert, deputy director of the Climate Prediction Center – a division of the National Weather Service. “This is a good time for people to review the outlook and begin preparing for what winter may have in store.”

“Other climate factors will play a role in the winter weather at times across the country,” added Halpert. “Some of these factors, such as the North Atlantic Oscillation, are difficult to predict more than one to two weeks in advance. The NAO adds uncertainty to the forecast in the Northeast and Mid-Atlantic portions of the country.”

This seasonal outlook does not project where and when snowstorms may hit or total seasonal snowfall accumulations. Snow forecasts are dependent upon winter storms, which are generally not predictable more than several days in advance.

The beneficial effects of La Niña on the Indian monsoon have already been seen this year. But after the very cold winter in the Southern Hemisphere it remains to be seen if warm and dry conditions  are established in the South American summer now approaching.

From The Canadian Encyclopedia:

La Niña normally exerts much less of a global impact than El Niño, enhancing conditions that are more or less normal. Thus, under La Niña’s grip, normally wet Indonesia becomes wetter, and winters in Canada are often colder and snowier than normal. However, the weather associated with La Niña tends to be quite variable depending on such factors as its strength, the depth and geographic extent of the cool waters and the pre-existing atmospheric circulation. Among the normal weather effects of La Niña are wetter monsoons and flooding on the Indian subcontinent; torrential rains and floods in southeast Asia and northern and eastern Australia; cool and wet winters in southeastern Africa; and warm and dry conditions along the coast of Peru and Ecuador.

La Niña favours the formation of more and intense hurricanes in the North Atlantic Ocean. Three recent La Niña periods – 1988-89, 1995-96 and 1997-98 – were among the most active periods this century for Atlantic hurricanes.

North America typically feels the effects of La Niña during the winter and early spring. Wetter-than-normal conditions occur across the Pacific Northwest, British Columbia and Alaska. On the other hand, it delivers drier, warmer and sunnier weather along the southern tier of the United States from California through Texas to Florida. Northern states west of the Great Lakes generally experience colder and snowier winters. During La Niña episodes, there is also a greater risk of wildfires in Florida and dryness in the North American plains. The great dust bowl drought of the 1930s is thought to have been caused by a decade of La Niña-like conditions and was likely responsible, in part, for the severe drought in the American midwest in 1988.

During La Niña winters in Canada, the jet stream assumes its more normal mid-continental location. Because the mild air and cold air are never too far away, winters usually comprise alternating bouts of freezing and thawing. Overall, in Western and Central Canada, most La Niña winters tend to be colder than normal by 1 to 2°C, and snowfall amounts are greater than normal from the interior of BC to the St Lawrence Valley. During 8 La Niña episodes since 1950, 6 of the winters across Canada were colder than normal (2 were near-normal) and 7 were snowier than normal.
