I posted the organizational structure of the IPCC and it's meanderings within the scientific community and world governments a few pages back. Morgan seems to have ignored that and is yet again overdosing on those amnesia pills. Blame it on the western medicine, I guess.
I prefer the decline of reason...the level of scientific literacy is low, though to be fair you don't even need to be at a basic level of scientific literacy to review the structure of an organization.
Here's a fine example of horrid reporting by the media.
Here's the WSJ article:
Climate of uncertainty-
Global warming science is still evolving; will future IPCC reports reflect that?
I mean they can't even get past the sub-heading without asking a question that is easilly answered. The rest of the article follows from the false notion that these uncertainties aren't acknowledged.
See for yourself.
The first assessment report, in 1990:
We are certain of the following: Emissions resulting from human activities are substantially increasing the atmospheric concentrations of the greenhouse gases: carbon dioxide, methane, chlorofluorocarbons (CFCs) and nitrous oxide. These increases will enhance the greenhouse effect, resulting on average in an additional warming of the Earth’s surface.
Our judgment is that: Global mean surface air temperature has increased by 0.3 to 0.6°C over the last 100 years, with the five global-average warmest years being in the 1980’s.
The size of the warming over the last century is broadly consistent with the prediction by climate models, but is also of the same magnitude as natural climate variability…. The unequivocal detection of the enhanced greenhouse effect from observations is not likely for a decade or more.
So, they are actually quite explicit about the state of the science in 1990. Some warming, consistent with models, but indistinguishable from the natural variability in the climate system.
Fast forward, to 1995, and the second assessment for policymakers:
Global mean surface air temperature has increased by between about 0.3 and 0.6°C since the late 19th century; the additional data available since 1990 and the re-analyses since then have not significantly changed this range of estimated increase.
More convincing recent evidence for the attribution of a human effect on climate is emerging from pattern-based studies, in which the modelled climate response to combined forcing by greenhouse gases and anthropogenic sulphate aerosols is compared with observed geographical, seasonal and vertical patterns of atmospheric temperature change. These studies show that such pattern correspondences increase with time, as one would expect, as an anthropogenic signal increases in strength. Furthermore, the probability is very low that these correspondences could occur by chance as a result of natural internal variability only. The vertical patterns of change are also inconsistent with those expected for solar and volcanic forcing.
Our ability to quantify the human influence on global climate is currently limited because the expected signal is still emerging from the noise of natural variability, and because there are uncertainties in key factors. These include the magnitude and patterns of long-term natural variability and the time-evolving pattern of forcing by, and response to, changes in concentrations of greenhouse gases and aerosols, and land surface changes. Nevertheless, the balance of evidence suggests that there is a discernible human influence on global climate.
The understanding has evolved, more evidence has accrued, but the uncertainty is still limiting unequivocal attribution because "the expected signal is still emerging from the noise of natural variability".
Fast forward now to the third assessment report, in 2001:
Since the release of the Second Assessment Report (SAR4), additional data from new studies of current and palaeoclimates, improved analysis of data sets, more rigorous evaluation of their quality, and comparisons among data from different sources have led to greater understanding of climate change
....
The global average surface temperature (the average of near surface air temperature over land, and sea surface temperature) has increased since 1861. Over the 20th century the increase has been 0.6 ± 0.2°C5, 6 (Figure 1a). This value is about 0.15°C larger than that estimated by the SAR for the period up to 1994, owing to the relatively high temperatures of the additional years (1995 to 2000) and improved methods of processing the data. These numbers take into account various adjustments, including urban heat island effects. The record shows a great deal of variability; for example, most of the warming occurred during the 20th century, during two periods, 1910 to 1945 and 1976 to 2000.

Climate Change 2001: The Scientific Basis is the most comprehensive and up-to-date scientific assessment of past, present and future climate change. The report:
- Suggests gaps in information and understanding that remain in our knowledge of climate change and how these might be addressed.
So, again, more understanding, and identifies areas of uncertainty which need to be addressed, and even suggests how to do so.
And finally, the fourth assessment released in 2007:
Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level.
The updated 100-year linear trend (1906 to 2005) of 0.74°C [0.56°C to 0.92°C] is therefore larger than the corresponding trend for 1901 to 2000 given in the TAR of 0.6°C [0.4°C to 0.8°C].
Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations. This is an advance since the TAR’s conclusion that “most of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations”. Discernible human influences now extend to other aspects of climate, including ocean warming, continental-average temperatures, temperature extremes and wind patterns.
Very clearly, as new studies, new sources of data, and most importantly perhaps, as time has progressed, the understanding of our climate has evolved. Many of the uncertainties have been identified and addressed, some remain.
The WSJ article is simply false. Yet it will undoubtedly just reinforce the ignoramuses out there who have never once decided to look for themselves at the actual reports.
