* Ooops! Has Global Warming Stopped?
I think you may find the little graph I have just produced [above, and in full below] of interest. It illustrates an intriguing mini-phenomenon: since 1998, ‘global warming’ appears to have - wait for it - stopped. The data is taken from the UK Met Office’s ‘HadCRUT3’ dataset, a globally-gridded product of near-surface temperatures, consisting of annual differences from 1961-90 normals. The full data set is available here, covering the period from 1850 to the present. The coloured ribbon shows the best estimate data from this set. But, what does it mean?
Of course, little can be gleaned from such a short data run of only 10-years [“‘Global warmers’ also please note, thank you”], but the temperature anomaly has clearly dipped, and then flat-lined below its 1998 anomaly peak - and for nine years now. In other words, since 1998 there has been no global warming [not even any ‘global warming’]. Yet, atmospheric CO2 has continued to rise, from c. 368 ppmv in 1998 to c. 384 ppmv in November, 2007 [see: ‘CO2 Signals From The Past’, February 1]. Moreover, politicians persist in claiming that temperature is rising faster than at any other time in the history of the whole Earth..... but then, we always believe our politicians, don’t we?
So, does this mean to say that other factors may actually be driving climate and temperature? Oh me, Oh my! What a shock! Perhaps with all those shredders in our offices and homes, there are just too many tiny bits and bobs of credit cards floating up into the air and cooling the atmosphere? Or, weddings may have increased in number, and particulate confetti is having an unknown effect? Or, then again, the rise out of the ‘Little Ice Age’, which ended c. 1880, might just be stuttering a tad? Who knows?
Time to get my skates on. But, whatever it is - for the moment, at least - Global Warming Has Stopped!
Shout it from the rooftops, from your PCs, and from your Apple Macs.
Brrr! Time for a single malt to celebrate. “Slàinte!”

* Conviene investigar, cada uno con la información que caiga en sus manos hasta el agotameinto si quieres aclarar algo. Con la gran manipulación que existe hoy en los medios de comunicación tradicionales, ya no te puedes fiar ni de los telediarios de algunos medios, donde meten cuñas publicitarias pagados por los intereses, como si fuesen noticias cuando son inyecciones phiscológicas encubiertas. Se han prostituido hasta tales límites, que te lo puedes creer hoy todo, en materias de corruptelas. ¡Gracias por hacernos pensar en frio! Desde Oviedo.

De hecho el supuesto calentamiento global se está convirtiendo en enfriamiento. Este invierno fue muy duro en muchos país del mundo, donde se han batido records : por primera vaz hubo nieve ¡ en Bagdad !
Y se sabe que no ha subido la temperatura promedia del mundo desde 1998. Tampoco suben los oceanos.
Científicos con reputación internacional se vuelven cada vez más numerosos en contra del IPCC y de sus incompletos modelos que pretenden predecir el clima.
La estafa del calentamiento se da la mano con el timo de la energía eólica, y ahora de la solar, la cual cuesta 10 veces más que la energía tradicional. ¡ A ver que pasará con las facturas de luz ! Y cuando pasa una nube, ¡ apagón ! Así que construir también centrales de carbón para no tener apagones.
¡ Vaya desproposito !

Pero la mayor fuente de CO2 son los océanos con diferencia? Afortunadamente, son los mayores sumideros de CO2 del mundo...

* Temperature Monitors Report Widescale Global Cooling
Michael Asher (Blog) - February 26, 2008 12:55 PM
Twelve-month long drop in world temperatures wipes out a century of warming.
Over the past year, anecdotal evidence for a cooling planet has exploded. China has its coldest winter in 100 years. Baghdad sees its first snow in all recorded history. North America has the most snowcover in 50 years, with places like Wisconsin the highest since record-keeping began. Record levels of Antarctic sea ice, record cold in Minnesota, Texas, Florida, Mexico, Australia, Iran, Greece, South Africa, Greenland, Argentina, Chile -- the list goes on and on.
No more than anecdotal evidence, to be sure. But now, that evidence has been supplanted by hard scientific fact. All four major global temperature tracking outlets (Hadley, NASA's GISS, UAH, RSS) have released updated data. All show that over the past year, global temperatures have dropped precipitously. A compiled list of all the sources can be seen here. The total amount of cooling ranges from 0.65C up to 0.75C -- a value large enough to wipe out most of the warming recorded over the past 100 years. All in one year's time. For all four sources, it's the single fastest temperature change ever recorded, either up or down. Scientists quoted in a past DailyTech article link the cooling to reduced solar activity which they claim is a much larger driver of climate change than man-made greenhouse gases. The dramatic cooling seen in just 12 months time seems to bear that out. While the data doesn't itself disprove that carbon dioxide is acting to warm the planet, it does demonstrate clearly that more powerful factors are now cooling it. Let's hope those factors stop fast. Cold is more damaging than heat. The mean temperature of the planet is about 54 degrees. Humans -- and most of the crops and animals we depend on prefer a temperature closer to 70. Historically, the warm periods such as the Medieval Climate Optimum were beneficial for civilization. Corresponding cooling events such as the Little Ice Age, though, were uniformly bad news.
Update 2/27: The graph for HadCRUT (above), as well as the linked graphs for RSS and UAH are generated month-to-month; the temperature declines span a full 12 months of data. The linked GISS graph was graphed for the months of January only, due to a limitation in the plotting program. Anthony Watts, who kindly provided the graphics, otherwise has no connection with the column. The views and comments are those of the author only.

La variación de temperatura terrestre oscila en términos razonables debido a la actividad solar y es previsible que siga así. Nuevos yacimientos se suman a los ya explotados o en explotación incitandonos a derrochar, pero la tendencia de consumo de recursos es a la baja, somos austeros. La desforestación se debe a las variables climáticas, donde es obra del hombre apenas tiene relevancia y se debe a minifundios familiaries de explotación agrícola. Nuevas especies animales,vegetales y fungi surgen por doquier(se ha descubierto una nueva rana en la cuenca amazónica). La natalidad también sigue una tendencia a la baja aun cuando está probado que el planeta tierra puede mantener 700.000.000.000 de seres humanos más. Todo va estupendamente.
