More Hot Air

Now according to the Government, Carbon Dioxide, which we exhale everyday and is essential for life, is classified as a "pollutant" to be regulated under the Clean Air Act!

New pollution limits seen for cars, big plants

The Environmental Protection Agency took a big step in that direction, concluding that carbon dioxide and five other greenhouse gases are a major hazard to Americans' health.
...
The court case, brought by Massachusetts, focused only on emissions from automobiles. But it is widely assumed that if the EPA must regulate emissions from cars and trucks, it will have no choice but to control similar pollution from power plants and industrial sources.

And why does it necessarily stop there? You now officially breathe out a pollutant.

Everyone who wants to save the planet, stop breathing.

Look at this chart:



Another blogger refers to that chart and points out cogently:

The sharper-eyed among you will notice that the great civilisations of the Ancient World arose and spread during a period of global warming a great deal worse than Al Gore's worst-case-scenario predictions.

Presumably Agamemnon drove everywhere in his 747.

The Goreite priesthood must therefore logically deduce that polar bears sprang out of the Void into existence about the same time Jesus did. Because the earth was too hot for them to survive before then.

And then they did so again after they were all wiped out ~1,000AD.

Persistent little bastards, aren't they?

THE IPCC’S FAILURE OF PREDICTING THE TEMPERATURE CHANGE DURING THE FIRST DECADE

The global average temperature stopped increasing after 2000 against the IPCC’s prediction of continued rapid increase. It is a plain fact and does not require any pretext. Their failure stems from the fact that the IPCC emphasized the greenhouse effect of CO2 by slighting the natural causes of temperature changes.

The changes of the global average temperature during the last century and the first decade of the present century can mostly be explained by two natural causes, a linear increase which began in about 1800 and the multi-decadal oscillation superposed on the linear increase. There is not much need for introducing the CO2 effect in the temperature changes. The linear increase is the recovery (warming) from the Little Ice Age (LIA), which the earth experienced from about 1400 to 1800.

The halting of the temperature rise during the first decade of the present century can naturally be explained by the fact that the linear increase has been overwhelmed by the superposed multi-decadal oscillation which peaked in about 2000.
...
The high temperatures predicted by the IPCC in 2100 (+2~6°C) are simply an extension of the observed increase from 1975 to 2000, which was caused mainly by the multi-decadal oscillation. The Global Climate Models (GCMs) are programmed to reproduce the observed increase from 1975 to 2000 in terms of the CO2 effect and to extend the reproduced curve to 2100.

It is advised that the IPCC recognize at least the failure of their prediction even during the first decade of the present century; a prediction is supposed to become less accurate for the longer future.

More details from Dr. Akasofu here.

He states:

Some of the weak points in the present IPCC Report are:

--There has recently been so much attention focused on the CO2 effect, the Little Ice age has been forgotten. The recovery rate from the Little Ice Age may be as much as 0.5°C/100 years, comparable to the present warming trend of 0.6°C/100 years. The warming caused by the linear change must be carefully evaluated and subtracted in determining the greenhouse effect.

--There was no critical analysis of the mid-century change; the temperature rose between 1910 and 1940, similar in magnitude and rate to the present rise after 1975. Further, the temperature decreased from 1940 to 1975, in spite of the fact that the release of CO2 increased rapidly. At that time, we had similar debates about imminent “global cooling” (the coming of a new ice age) in the 1970s.

--It is crucial to investigate any difference between the 1910-40 increase and the increase after 1975, since the former is likely to be due to natural causes, rather than the greenhouse effect.

--The most prominent warming (twice the global average) took place in the Arctic, particularly in the continental arctic, during the last half of the 20th century, as stated in the IPCC Report, but it disappeared during the last decade or so. Further, the IPCC models cannot reproduce the prominent continental warming, in spite of the fact that the measured amount of CO2 was considered. This particular warming is likely to be part of multi-decadal oscillations, a natural cause.

--It is also important to know that the temperature has been increasing almost linearly from about 1750, or earlier, to the present, in addition to multi-decadal oscillations, such as the familiar El Niño. These are natural changes.

--Both changes are significant. Until they can be quantitatively more carefully examined and subtracted from the present trend, it is not possible to determine the manmade greenhouse effect. Therefore, there is no firm basis to claim “most” in the IPCC Report.

--The IPCC should have paid more attention to climate change in the Arctic.

--The mid-century (1940-1975) alarm of a coming Ice Age teaches a very important lesson to all of us, including climate researchers. It is not possible to forecast climate change (warming or cooling) in the year 2100 based on a few decades of data alone.

--Further, it is very confusing that some members of the media and some scientific experts blame “global warming” for every “anomalous” weather change, including big snowfalls, droughts, floods, ice storms, and hurricanes. This only confuses the issue.

At the International Arctic Research Center, which was established under the auspices of the “US-Japan Common Agenda” in 1999, our researchers are working on the arctic climate change issues mentioned in the above, in particular, in distinguishing natural changes and the manmade greenhouse effects in the Arctic. The term “most” is very inaccurate.

We must restore respectability – by that I mean scientific rigor - to the basic science of climatology. We must also stop “tabloid” publications in science. Only then, can we make real progress in projecting future temperature change. Although I have been “designated” by the news media as “Alaska’s best known climate change skeptic,” I am a critic, not a skeptic. Science without criticism could go astray.
