More than seven in 10 voters insist that they would not be willing to pay higher taxes in order to fund projects to combat climate change, according to a new poll released to coincide with the local elections.

The survey also reveals that most Britons believe “green” taxes on 4x4s, plastic bags and other consumer goods have been imposed to raise cash rather than change our behaviour, while two-thirds of Britons think the entire green agenda has been hijacked as a ploy to increase taxes.

Clearly more brainwashing and propaganda is required.

Writing in Science, Met Office researchers project that at least half of the years between 2009 and 2014 are likely to exceed existing records.

However, the Hadley Centre researchers said that the influence of natural climatic variations were likely to dampen the effects of emissions from human activities between now and 2009.

But over the decade as a whole, they project the global average temperature in 2014 to be 0.3C warmer than 2004.

Currently, 1998 is the warmest year on record, when the global mean surface temperature was 14.54C (58.17F).

Global temperatures for 2008 will be slightly cooler than last year as a result of the cold La Nina current in the Pacific, UN meteorologists have said.

Mr Jarraud told the BBC that the effect was likely to continue into the summer, depressing temperatures globally by a fraction of a degree.

This would mean that temperatures have not risen globally since 1998 when El Nino warmed the world.

A minority of scientists question whether this means global warming has peaked and the earth has proved more resilient to greenhouse gases than predicted.

Experts at the UK Met Office’s Hadley Centre for forecasting in Exeter said the world could expect another record temperature within five years or less, probably associated with another episode of El Nino.

BBC April 2008: Global temperatures ‘to decrease’

The Earth’s temperature may stay roughly the same for a decade, as natural climate cycles enter a cooling phase, scientists have predicted.

A new computer model developed by German researchers, reported in the journal Nature, suggests the cooling will counter greenhouse warming.

However, temperatures will again be rising quickly by about 2020, they say.

BBC 1 May 2008: Next decade ‘may see no warming’

Global warming will stop until at least 2015 because of natural variations in the climate, scientists have said. Researchers studying long-term changes in sea temperatures said they now expect a “lull” for up to a decade while natural variations in climate cancel out the increases caused by man-made greenhouse gas emissions. The average temperature of the sea around Europe and North America is expected to cool slightly over the decade while the tropical Pacific remains unchanged. This would mean that the 0.3°C global average temperature rise which has been predicted for the next decade by the UN’s Intergovernmental Panel on Climate Change may not happen, according to the paper published in the scientific journal Nature.

Editor’s Summary: Decadal climate prediction

Warming Antarctic waters begin to cool

Antarctica’s deep ocean waters are getting colder after years of warming, say researchers who have just returned from a Southern Ocean voyage aboard the German research vessel Polarstern.

PASADENA, Calif. – Boosted by the influence of a larger climate event in the Pacific, one of the strongest La Niñas in many years is slowly weakening but continues to blanket the Pacific Ocean near the equator, as shown by new sea-level height data collected by the U.S.-French Jason oceanographic satellite.

This La Niña, which has persisted for the past year, is indicated by the blue area in the center of the image along the equator. Blue indicates lower than normal sea level (cold water). The data were gathered in early April.

The image also shows that this La Niña is occurring within the context of a larger climate event, the early stages of a cool phase of the basin-wide Pacific Decadal Oscillation. The Pacific Decadal Oscillation is a long-term fluctuation of the Pacific Ocean that waxes and wanes between cool and warm phases approximately every five to 20 years. In the cool phase, higher than normal sea-surface heights caused by warm water form a horseshoe pattern that connects the north, west and southern Pacific, with cool water in the middle. During most of the 1980s and 1990s, the Pacific was locked in the oscillation’s warm phase, during which these warm and cool regions are reversed. For an explanation of the Pacific Decadal Oscillation and its present state, see: http://jisao.washington.edu/pdo/ and http://www.esr.org/pdo_index.html .

A La Niña is essentially the opposite of an El Niño. During El Niño, trade winds weaken and warm water occupies the entire tropical Pacific Ocean. Heavy rains tied to the warm water move into the central Pacific Ocean and cause drought in Indonesia and Australia while altering the path of the atmospheric jet stream over North and South America. During La Niña, trade winds are stronger than normal. Cold water that usually sits along the coast of South America is pushed to the middle of the equatorial Pacific. A La Niña changes global weather patterns and is associated with less moisture in the air, and less rain along the coasts of North and South America.

“This multi-year Pacific Decadal Oscillation ‘cool’ trend can intensify La Niña or diminish El Niño impacts around the Pacific basin,” said Bill Patzert, an oceanographer and climatologist at NASA’s Jet Propulsion Laboratory, Pasadena, Calif. “The persistence of this large-scale pattern tells us there is much more than an isolated La Niña occurring in the Pacific Ocean.”

Sea surface temperature satellite data from the National Oceanic and Atmospheric Administration also clearly show a cool Pacific Decadal Oscillation pattern, as seen at: http://www.cdc.noaa.gov/map/images/sst/sst.anom.gif . The shift in the Pacific Decadal Oscillation, with its widespread Pacific Ocean temperature changes, will have significant implications for global climate. It can affect Pacific and Atlantic hurricane activity, droughts and flooding around the Pacific basin, marine ecosystems and global land temperature patterns.

“The comings and goings of El Niño, La Niña and the Pacific Decadal Oscillation are part of a longer, ongoing change in global climate,” said Josh Willis, a JPL oceanographer and climate scientist. Sea level rise and global warming due to increases in greenhouse gases can be strongly affected by large natural climate phenomenon such as the Pacific Decadal Oscillation and the El Nino-Southern Oscillation. “In fact,” said Willis, “these natural climate phenomena can sometimes hide global warming caused by human activities. Or they can have the opposite effect of accentuating it.”

Jason’s follow-on mission, the Ocean Surface Topography Mission/Jason-2, is scheduled for launch this June and will extend to two decades the continuous data record of sea surface heights begun by Topex/Poseidon in 1992. JPL manages the U.S. portion of the Jason mission for NASA’s Science Mission Directorate, Washington, D.C.
