World may not be warming, say scientists

Quote:The United Nations climate panel faces a new challenge with scientists casting doubt on its claim that global temperatures are rising inexorably because of human pollution.

In its last assessment the Intergovernmental Panel on Climate Change (IPCC) said the evidence that the world was warming was “unequivocal”.

It warned that greenhouse gases had already heated the world by 0.7C and that there could be 5C-6C more warming by 2100, with devastating impacts on humanity and wildlife. However, new research, including work by British scientists, is casting doubt on such claims. Some even suggest the world may not be warming much at all.

“The temperature records cannot be relied on as indicators of global change,” said John Christy, professor of atmospheric science at the University of Alabama in Huntsville, a former lead author on the IPCC.

...more...

This is worth emphasis:

Quote:Terry Mills, professor of applied statistics and econometrics at Loughborough University, looked at the same data as the IPCC. He found that the warming trend it reported over the past 30 years or so was just as likely to be due to random fluctuations as to the impacts of greenhouse gases. Mills’s findings are to be published in Climatic Change, an environmental journal.

The corrections to the IPCC reports are building up steam.

It is factually “unequivocal”!

[Derek]

"human pollution" a phrase "they" are very fond of, and the press has not got to grips with yet.
This is becoming more and more transparent to most people.

Real "greens" emit CO2, because,
CO2 is plant food, NOT (human) pollution, with no proven effect upon climate.

Well, maybe to the IPCC, the word "unequivocal" means "doubtful, with the possibility of not at all"?

Opposing scientists should say to hard liners... Don't just talk about humans causing global warming... Prove it!!!

Scientists who make off the wall doomsday statements with no credible proof should face a criminal investigation if proven wrong. Then, maybe others would be more careful in the future.

Of course not... Temperature indicators can't be a hundred percent accurate, and a hundred percent accuracy that's what scientists must have to prove their wild doomsday theories.

despite how i like to rub it in the IPCC's face about global warming, i wish it was true given all the snow and cold temps that keep persisting

Agree. I'm certainly rooting for a return to past climate optimums.

We call them optimums for a reason. Don't you just know that AGW supporters wish climate optimums weren't already named by the time they arrived on the scene? What an inconvenient name!

New research confirms that Earth's upper atmosphere is cooling off.

Quote:The highest levels of our atmosphere are poorly understood, especially the thermosphere. At an altitude between 60 and 180 kilometers, it is the region where the Sun's energy begins to interact with atmospheric particles. Just how this dynamic relationship proceeds is still under investigation, but according to a recent press release from the the University Corporation for Atmospheric Research (UCAR), the thermosphere has experienced a tenfold decline in temperature since 2002.

Things are happening in the atmosphere/biosphere nobody understands or can predict.

Indeed they are, and its a travesty that some scientists haven't the humility to admit they actually know very little about the climate and its internal processes.

What we know about climate: 5%
What we don't know about climate: 5%
What we don't know we don't know about climate: 90%

Seems like the URL in Post #8 above has changed. Apologies.

This one seems to be the archived URL:

Thank you Richard111, a very interesting link,
and if I may take an excerpt from it..

" It has long been known that temperatures in the thermosphere are dependent on solar radiation.
Extreme ultraviolet light is absorbed by the residual oxygen and becomes electrically charged, with increasing molecular motion.
Fast molecular motion is known as heat, so even though a household thermometer would register temperatures below zero in the thermosphere,
it is considered hot, sometimes reaching over 1500º Celsius during solar maximum.

Since there are fewer molecules in the thermosphere, the amount of thermal energy per cubic centimeter is lower than it is at the surface
—there is not enough contact between molecules to transfer heat. "

So, what does the image actually depict, because it is not temperature as we experience it at the earth's surface.



I would of thought / tentatively suggest a profile of energy (mole movement x number of moles) per cubic metre would be a far more useful plot / visualisation,
than the "version" of temperature as plotted.
