Climate Change -- Has the Earth been cooling?

Video 8 of the Climate Change series is available:

This one covers the "recent 10 year cooling trend" myth and several other ones. Discussion of myth generation dynamics is also interesting. Enjoy.

And please, please do at least some basic research before cut-and-pasting stuff from blogs.

OK, but I don't see how a youtube video, from someone who readily admits that they know nothing about the science, and claim that the sun affect (by NASA) is a myth, really counts, either.

Anyway, just to rebuke the "NASA Myth part":

SUN’S DIRECT ROLE IN GLOBAL WARMING MAY BE UNDERESTIMATED, DUKE PHYSICISTS REPORT

At least 10 to 30 percent of global warming measured during the past two decades may be due to increased solar output rather than factors such as increased heat-absorbing carbon dioxide gas released by various human activities, two Duke University physicists report.



The physicists said that their findings indicate that climate models of global warming need to be corrected for the effects of changes in solar activity. However, they emphasized that their findings do not argue against the basic theory that significant global warming is occurring because of carbon dioxide and other “greenhouse” gases.



Nicola Scafetta, an associate research scientist working at Duke’s physics department, and Bruce West, a Duke adjunct physics professor, published their findings online Sept. 28, 2005, in the research journal Geophysical Research Letters.....

NASA Study Acknowledges Solar Cycle, Not Man, Responsible for Past Warming


Report indicates solar cycle has been impacting Earth since the Industrial Revolution

Some researchers believe that the solar cycle influences global climate changes. They attribute recent warming trends to cyclic variation. Skeptics, though, argue that there's little hard evidence of a solar hand in recent climate changes.

Now, a new research report from a surprising source may help to lay this skepticism to rest. A study from NASA’s Goddard Space Flight Center in Greenbelt, Maryland looking at climate data over the past century has concluded that solar variation has made a significant impact on the Earth's climate. The report concludes that evidence for climate changes based on solar radiation can be traced back as far as the Industrial Revolution....




Both of these studies, done by NASA, show that the Sun and its cycles influence 'Global Warming', so no, it is not a "Myth". Sorry, but I give the guy on that video as much creedence as the folks at 'Loose Change'.

Myth generation falls under the rubric of "cyber-tainment." Kind of like what I'm doing right now. Wasting time posting this message. It beats working.

lol do not copy and paste from blogs... only youtube and wikipedia are considered acceptable sources. I just wanna say it was 50 degrees in New Orleans last night.

double post

I just wanna say it was 50 degrees in New Orleans last night.

I am confused. According to the climate chart on Wikipedia for NO, the average low for March is 52.7 F.

Do you even read your stuff before you post it?

No one in the scientific communites denies that the Sun and its cycles have some influence global warming. The myth is that the Sun's cycles TOTALLY ACCOUNT FOR all the recent changes in global temperature. Your own post explicitly denies that.

Sheesh.

[Kunia5]

I read your post. Both Duke scientists both agreed there is anthropogenic global warming. That was mentioned twice in the article (from 2005). They just add a "possible" variation of between 10 and 30% because of stronger solar activity.

Doesn't really change the debate much.

Sorry, the scientists just agreed that greenhouse gases were adding to the earth's temperature; and not that it was anthropogenic.

Dude you posted a link to the very DailyTech article that the video exposes as a complete fraud

[alexey]

Yes, youtube videos and wikipedia articles THAT CONTAIN REFERENCES.

(things that do not contain references tend to be bunk, as that video demonstrated... do watch it when you get a chance)

Professor Jones told the BBC yesterday there was truth in the observations of colleagues that he lacked organisational skills, that his office was swamped with piles of paper and that his record keeping is ‘not as good as it should be’.

The data is crucial to the famous ‘hockey stick graph’ used by climate change advocates to support the theory.

Professor Jones also conceded the possibility that the world was warmer in medieval times than now – suggesting global warming may not be a man-made phenomenon.

this totally deserves its own thread...

In the 1970s, nearly 600 Canadian weather stations fed surface temperature readings into a global database assembled by the U.S. National Oceanic and Atmospheric Administration (NOAA). Today, NOAA only collects data from 35 stations across Canada.

Worse, only one station -- at Eureka on Ellesmere Island -- is now used by NOAA as a temperature gauge for all Canadian territory above the Arctic Circle.

They say NOAA collects no temperature data at all from Bolivia -- a high-altitude, landlocked country -- but instead “interpolates” or assigns temperature values for that country based on data from “nearby” temperature stations located at lower elevations in Peru, or in the Amazon basin.
