An Inconvenient Graph updated for May 2009

Al Gore / AIT Index: Global temperatures plunge further; have dropped .63°F (.35°C) since Al Gore released An Inconvenient Truth


The truth is getting ever more inconvenient for Al Gore.

Once again, as we do each month, GORE LIED has taken significant liberties with Dr. Roy Spencer’s monthly UAH globally averaged satellite-based temperature of the lower atmosphere.  We’ve marked it up with a red marker to more fully illustrate the really inconvenient truth – that temperatures have dropped significantly,  .63°F (.35°C), since Al Gore released his science fiction movie, An Inconvenient Truth at the Sundance Film Festival on January 24, 2006.

UK Met Office: Coldest Winter in over a decade but would have been even colder without global warming February 26, 2009

UK Met Office: Coldest Winter in over a decade but would have been even colder without global warming

By the  blogowner, honestclimate, February 26, 2009

Extract from UK Met Office news report:

Mild weather is expected to see out what remains of winter. Despite this, it is expected to be the coldest UK winter since 1995/96, according to provisional Met Office figures.

The low temperatures have also been accompanied at times by heavy snow. During early February, the heaviest snowfall for 18 years was experienced over many areas of the UK.

Reading further along

Natural variability of climate means that the UK will continue to see spells of colder weather at times. Although, if it had not been for the general warming already observed in global temperatures, this winter may well have been even colder.

Yes, thank goodness for global warming!

Satellite Data Show No Warming Before 1997. Changes Since Not Related to CO2 February 20, 2009

Satellite Data Show No Warming Before 1997. Changes Since Not Related to CO2

By Arno Arrak

Posted on ICECAP

A full analysis of satellite-measured lower tropospheric temperatures indicates that none of the global temperature variations from 1978 to 2008 can be attributed to the effect of carbon dioxide as a greenhouse gas. The record shows global climate oscillations with a period of three to five years and a peak-to-peak amplitude of 0.4 to 0.5 degrees Celsius about a common, fixed mean temperature that lasted from 1978 to 1997. Since this mean
temperature did not change for twenty years the late twentieth century warming touted by IPCC and others simply did not happen. The cause of these newly discovered climate oscillations is large-scale periodic movement of ocean waters from shore to shore, part of the El Nino � Southern Oscillation (ENSO) system. It is accompanied by a massive, periodic transfer of heat from the oceans to the atmosphere and back again which was previously
unsuspected and which is detectable even in land-based records. This major atmospheric phenomenon is missing from all IPCC Global Circulation Models (GCMs) and thereby invalidates conclusions drawn from their climate models. Satellite records show that this oscillatory period ended with a giant warming peak known as the “super El Nino of 1998.”

This unusual peak does not belong to the oscillatory ENSO system but interrupts it and could well be of cosmogenic origin. After it subsided the interrupted ENSO oscillation continued. But it had been energized from that warm peak and in three years the global temperature rose to a plateau 0.2 degrees above previous peaks. The expected climate downturn that should have followed failed to occur and temperature stayed up there for six years. It lasted from 2001 to 2007. This “twenty first century high,” together with the warming peak that preceded it, accounts for recent accelerated loss of arctic ice. Contrary to carbon dioxide theory the world temperature did not increase but stayed the same during this period. The period ended with a climate downturn in 2007.

Carbon dioxide cannot explain the lack of warming in the eighties and nineties, nor any of the abrupt warmings that followed, nor the stasis of the twenty first century high, nor the temperature downturn that followed it in 2007 and bottomed out in 2008. A direct comparison of these satellite data with ground-based measurements is also possible. Comparing satellite (UAH MSU LT) and land-based (HadCRUT3) data for the eighties and nineties gives HadCRUT3 a warming trend of 0.1 degrees Celsius per decade (one degree per century) while lower tropospheric satellite data show no warming at all. This is compounded by the fact that satellite measurements of midtropospheric temperature show a long-term cooling effect for this period. Looking for sources
of error in ground-based data one is led to the usual suspect, the urban heat island effect.

Fatal computer errors in IPCC climate models derive from the fact that none of the abrupt warmings and coolings on the record, especially since 1998, can be attributed to the greenhouse effect. Hence, all IPCC models purporting to predict (project??) climate a hundred years into the future are invalid and their predictions/projections must be discarded. To summarize: existing theory used by the IPCC can neither explain the observed climate nor predict the future. Carbon dioxide warming has been shown to be non-existent in the eighties and nineties, and the warming since 1998 is not carbonaceous in origin. It follows that Quijotic carbon dioxide policies like the Kyoto Protocol and the cap-and-trade laws should be abandoned. See post here.

Updated Al Gore / AIT Index: Globally averaged temperatures have decreased -.14°F (-.08°C) since An Inconvenient Truth was released

From Gore Lied, February 20, 2009

GORE LIED has been tracking the globally averaged temperatures since Al Gore’s science fiction movie, An Inconvenient Truth was released.

As we do each month GORE LIED has marked up in red Dr. Roy Spencer’s UAH Globally Averaged Satellite-Based Temperature of the Lower Troposphere monthly report, to show in vivid color Gore’s real inconvenient truth.

This month’s report:

Globally averaged temperatures have dropped approximately .14°F (.08°C) since An Inconvenient Truth was released.

That’s not all, a quick glance at the graph shows globally averaged temperatures have remained below the January 24, 2006 benchmark (when Gore’s movie was released at the Sundance Film Festival) except for the first few months of 2007.

Taking a Time Machine Ride Back to the 1960s or 1800s? February 9, 2009

Taking a Time Machine Ride Back to the 1960s or 1800s?

From ICECAP

By Joseph D’Aleo, CCM, AMS Fellow

There are signs our weather is taking a time machine ride back to the regimes of the 1960s or even the late 1700s early 1800s. Our climate operates in cycles, which favors different regimes of weather. We have come out of a few decades that thanks to a warm Pacific resulted in a dominance of El Ninos and its typical southern storm tracks and warm, dry western North America.

The Pacific has cooled and now favors La Ninas, which have dominated the last two winters. This has resulted in a more northern storm track (and as we reported in earlier stories (here and here and here), record monthly or seasonal snows).

See how cold PDOs of the 1947 to 1977 led to mainly La Ninas

The Atlantic is cooling too. The AMO has declined from its 2004/05 peak. The sum of the PDO and AMO we have shown correlates well with US annual temperatures.

In earlier reports, we have shown how the solar cycles also have a profound affect on climate (for example here and here). An active sun through direct and indirect factors leads to warming oceans and through them the land, and a quiet sun to cooling of oceans and land.

In the last century, we are with the cooling of the oceans, and a quiet sun most like the 1960s (graph below), a cold era as shown in the graph above.

Longer term the sun is behaving like it did in the last 1700s and early 1800s, leading many to believe we are likely to experience conditions more like the early 1800s (called the Dalton Minimum) in the next few decades. That was a time of cold and snow. It was the time of Charles Dickens and his novels with snow and cold in London (hmmmm).

During these cold modes, more La Nina winters like this occur, El Ninos occasionally develop, tend to be briefer and weaker and thus colder and snowier than the El Ninos of the warm eras. If a major volcano occurs, the cold deepens. See the complete story as posted on Intellicast here.
