Calentamiento global

¡Este calentamiento global me está matando! BTW, las temperaturas mínimas en el valle de Guatemala andan por los 8 y 10 grados centígrados; en tanto que en Quetzaltenango van entre 0 y 2 grados.

Calentamiento global y consenso

Existe un amplio consenso acerca del calentamiento global, ¿verdad? No. No es así.

De mi amigo Cris Lingle recibí la siguiente información importante, basada en datos comprobables y no en especulaciones basadas en perceciones, ni en consignas:

In 2004, history professor Naomi Oreskes performed a survey of research papers on climate change. Examining peer-reviewed papers published on the ISI Web of Science database from 1993 to 2003, she found a majority supported the “consensus view,” defined as humans were having at least some effect on global climate change. Oreskes’ work has been repeatedly cited, but as some of its data is now nearly 15 years old, its conclusions are becoming somewhat dated.

Medical researcher Dr. Klaus-Martin Schulte recently updated this research. Using the same database and search terms as Oreskes, he examined all papers published from 2004 to February 2007. The results have been submitted to the journal Energy and Environment… The figures are surprising.

Of 528 total papers on climate change, only 38 (7%) gave an explicit endorsement of the consensus. If one considers “implicit” endorsement (accepting the consensus without explicit statement), the figure rises to 45%. However, while only 32 papers (6%) reject the consensus outright, the largest category (48%) are neutral papers, refusing to either accept or reject the hypothesis.

¡Ups, fue sólo un error pequeño de la NASA!

Durante años, los alarmistas del calentamiento global han citado descubrimientos de la NASA, que aseguran que 1998 fue el año más caliente en los Estados Unidos de América; y que nueve de los 10 años más tórridos han ocurrido desde 1990. James Hansen, de la NASA, incluso ha asegurado que el gobierno gringo lo censura. Pero resulta que, ¡Ups!, siempre no, según un informe del National Center for Policy Analysis.

“Hansen got his math wrong. NASA has now quietly corrected
the records. The warmest year (out of the last 127 years) is
1934! And six out of the 10 warmest years occurred before 90
percent of the recent growth in greenhouse gases.

This story has been largely ignored by the mainstream press. The
Washington Post
did cover it, but their piece was mostly a defense
from Hansen, arguing that this was no big deal. If this error
had been the other way around, NASA would have issued news releases
and it would have been front page news in every paper in the country.

The Post story doesn’t even quote Stephen McIntyre, the researcher who
found NASA’s error. Nor does it give the backstory of how Hansen
wouldn’t share his data. Rather than raising serious questions about Hansen’s other claims, the Post“.

Si usted quiere leer la historia de forma más objetiva, por favor leala en The Toronto Star. Si usted ya tiene sus ideas hechas y no quiere ser confundido con hechos, ignore esta nota. La NASA no sólo hace volar astronautas bolos, también esparce bolas.

Humor y calentamiento global

Al Gore no inventó la Internet; pero si inventó el calentamiento global.

Calentamiento en Marte y calentamiento en la Tierra

El calentamiento del planeta Tierra es un hecho; pero, si hay calentamiento en Marte y también aquí, ¿qué estamos aprendiendo sobre ese fenómeno? He aquí hechos muy interesantes publicados por National Geographic.

Calentamiento global, ¿qué tanto sabes de eso?

Del amigo y lector Roberto Ibarra recibí el Global Warming Test y sirve muy bien para averiguar qué tanto sabe uno acerca del calentamiento global.

Como es entretenido y educativo lo comparto con ustedes y les recomiendo que lo hagan.

Observaciones de Pedro sobre Al Gore

De mi amigo y lector, Pedro, he recibido estas observaciones en el contexto de The Great Global Warming Swindle:

Esta semana Gore tuvo la oportunidad de declarar ante el Congreso de los Estados Unidos sobre este tema. En mi opinión no le fue muy bien. El tenía que entregar un depostion de sus declaraciones 48 horas antes de declarar y no las entregó sino hasta ese mismo día en la mañana. Cuando se inició la sesión, los republicanos la abrieron con unos opening statements durante los cuales Gore optó por no estar presente. Al finalizar sus declaraciones se inició un período de preguntas, algunas de las cuales Gore optó por no responder, poniéndose a hablar de otra cosa relacionada al tema de global warming pero sin responder a la pregunta específica. En mi opinión lució muy mal. Por aparte, el artículo que apareció en The New York Times recientemente haciendo ver el punto que la evidencia sobre global warming no es concluyente, sino que al contrario existe mucha evidencia que refuta el sobre calentamiento, también afectó mucho a Gore. Sobre todo tomando en cuenta el medio en el que fue publicado. Considero que si Gore está haciendo todo esto para relanzar su candidatura esta semana no consiguió el springboard deseado.

La gran estafa del calentamiento global

El canal 4, de Gran Breteña produjo un documental titulado La gran estafa del calentamiento global o The Great Global Warming Swindle. En él, científicos distinguidos, especializados en el clima, se refieren en términos sencillos (y en inglés) a aquel fenómeno. El documental todavía no es transmmitido en los EUA; pero ya está en la Web. Además, Thomas Sowell, en The Atlasphere escribió un ensayito al respecto y ese lo pueden encontrar aquí, debajo del documental citado.

Opinion Editorial
Global Warming Swindle
By Thomas Sowell*
Mar 23, 2007

Britain’s Channel 4 has produced a devastating documentary titled “The Great Global Warming Swindle.” It has apparently not been broadcast by any of the networks in the United States. But, fortunately, it is available on the Internet.

Distinguished scientists specializing in climate and climate-related fields talk in plain English and present readily understood graphs showing what a crock the current global warming hysteria is.

These include scientists from MIT and top-tier universities in a number of countries. Some of these are scientists whose names were paraded on some of the global warming publications that are being promoted in the media — but who state plainly that they neither wrote those publications nor approved them.

One scientist threatened to sue unless his name was removed.

While the public has been led to believe that “all” the leading scientists buy the global warming hysteria and the political agenda that goes with it, in fact the official reports from the United Nations or the National Academy of Sciences are written by bureaucrats — and then garnished with the names of leading scientists who were “consulted,” but whose contrary conclusions have been ignored.

There is no question that the globe is warming but it has warmed and cooled before, and is not as warm today as it was some centuries ago, before there were any automobiles and before there was as much burning of fossil fuels as today.

None of the dire things predicted today happened then.

The British documentary goes into some of the many factors that have caused the earth to warm and cool for centuries, including changes in activities on the sun, 93 million miles away and wholly beyond the jurisdiction of the Kyoto treaty.

According to these climate scientists, human activities have very little effect on the climate, compared to many other factors, from volcanoes to clouds.

These climate scientists likewise debunk the mathematical models that have been used to hype global warming hysteria, even though hard evidence stretching back over centuries contradicts these models.

What is even scarier than seeing how easily the public, the media, and the politicians have been manipulated and stampeded, is discovering how much effort has been put into silencing scientists who dare to say that the emperor has no clothes.

Academics who jump on the global warming bandwagon are far more likely to get big research grants than those who express doubts — and research is the lifeblood of an academic career at leading universities.

Environmental movements around the world are committed to global warming hysteria and nowhere more so than on college and university campuses, where they can harass those who say otherwise. One of the scientists interviewed on the British documentary reported getting death threats.

In politics, even conservative Republicans seem to have taken the view that, if you can’t lick ‘em, join ‘em. So have big corporations, which have joined the stampede.

This only enables the green crusaders to declare at every opportunity that “everybody” believes the global warming scenario, except for a scattered few “deniers” who are likened to Holocaust deniers.

The difference is that we have the hardest and most painful evidence that there was a Holocaust. But, for the global warming scenario that is causing such hysteria, we have only a movie made by a politician and mathematical models whose results change drastically when you change a few of the arbitrarily selected variables.

No one denies that temperatures are about a degree warmer than they were a century ago.

What the climate scientists in the British documentary deny is that you can mindlessly extrapolate that, or that we are headed for a climate catastrophe if we don’t take drastic steps that could cause an economic catastrophe.

“Global warming” is just the latest in a long line of hysterical crusades to which we seem to be increasingly susceptible.

The Great Global Warming Swindle

* Thomas Sowell is a Senior Fellow at The Hoover Institution at Stanford University in California. He has published dozens of books on economics, education, race, and other topics. His most recent book is Black Rednecks and White Liberals, in which he argues that “internal” cultural habits of industriousness, thriftiness, family solidarity, and reverence for education often play a greater role in the success of ethnic minorities than do civil-rights laws or majority prejudices.

An Inconvenient Doubt

From a Rapt Audience, a Call to Cool the Hype, es el título del reportaje publicado por la sección científica de The New York Times. En él se exponen las dudas expresadas por algunos científicos debido a imprecisiones, exageraciones y errores contenidos en An Inconvenient Truth, el laureado documental de Al Gore. Esas imprecisiones “razonables para un político”, es bueno conocerlas para poner en su justa dimensión el alarmismo que ha desatado el citado documental.
