  Revised 1996 IPCC Guidelines
UNFCCC COP3 held in 1997 in Kyoto reaffirmed that the Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories should be used as "methodologies for estimating anthropogenic emissions by sources and removals by sinks of greenhouse gases" in calculation of legally-binding targets during the first commitment period.
The Revised 1996 IPCC Guidelines contain three volumes, each of which provides assistance to the analyst in the preparation of national GHG inventories.
These instructions are intended for all users of the IPCC Guidelines and provide the primary means of ensuring that all reports are consistent and comparable.

  IPCC's most essential model errors
IPCC's CO increment to 700 ppm is by a factor 1.6 higher.
IPCC argues that at tropopause level the water vapor density is negligible, which is true – but in reality the forcing stems from absorption and back-radiation within the lower troposphere near ground where we find the bulk of water vapor.
IPCC authors so far refused to disclose details about the modelling assumptions and computation of their core parameter, demanding us to believe in their results – which is an unprecedented offence against rules in public funded science, and the TAR again follows this line.

 IPCC
IPCC Working Groups and Task Forces are mandated to have clearly-defined and approved terms of reference and work plans as established by the Panel, and are open-ended.
IPCC activities, including travel costs for experts from developing countries and from countries with economies in transition, are financed through voluntary contributions from governments as well as to a small degree from the UNFCCC.
The first IPCC Guidelines for National Greenhouse Gas Inventories were prepared in close collaboration with the OECD and the IE in 1994 and adopted by the UNFCCC-COP in 1995 as guidelines for the preparation of national communications by developed country (Annex I) Parties.

 HDP-Intergovernmental Panel on Climate Change   (Site not responding. Last check: 2007-10-10)
The IPCC is charged with assessing various scientific components of the climate change issue, such as potential effects of greenhouse gas emissions and modification of the Earth's radiation balance.
IPCC also examines the environmental and socioeconomic consequences of climate change and evaluates possible response strategies for the management of climate change.
In addition to its role as an international scientific body, IPCC serves as the scientific advisor to The Framework Convention on Climate Change.

 The IPCC Carbon Dioxide Predictions are Errorneous
The IPCC predictions do not seem to be the result of any computer simulation, they seem to be calculated from the emission scenario directly by a simple mass balance using the wild guess of a constant airborne fraction of 50% for the next hundred years.
Every prediction of what is going to happen in the future is very uncertain, but it seems obvious that the IPCC model overpredicts the carbon dioxide concentration for the year 2100 with the scenario IS92a by at least 100 ppm.
The IPCC carbon dioxide predictions are cited in mass media all over the world as the scientific truth although they tell a different story than the real measurements do.

 The IPCC Assessment of Global Warming 2001
The IPCC carries out major assessments of the state of knowledge and understanding about every five years, the first in 1990, the second in 1995, and the third was completed in early 2001.
In 1995 the IPCC assessment concluded that "the balance of evidence suggests that there is a discernible human influence on global climate".
Thus the headline in IPCC (2001) is "There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities".

 IPCC Third Assessment Report - Wikipedia, the free encyclopedia
Statements of the IPCC or information from the TAR are often used as a reference showing a scientific consensus on the subject of global warming.
The TAR estimate for the climate sensitivity is 1.5 to 4.5 °C; and the average surface temperature is projected to increase by 1.4 to 5.8 Celsius degrees over the period 1990 to 2100, and the sea level is projected to rise by 0.1 to 0.9 metres over the same period.
IPCC predictions are based on the same models used to establish the importance of the different factors in global warming.

 Climate scientists issue dire warning | Science | Guardian Unlimited
The IPCC's removal of the upper temperature estimation is posited on new predictions about how the atmosphere would react to the carbon blanket wrapped around it.
The most recent IPCC report, published in 2001, said this would increase global temperatures by between 1.4 and 5.8C by 2100, and that sea levels would rise by between 0.09 and 0.88 metres.
The IPCC findings mirror a British report on avoiding dangerous climate change published last month, in which Mr Blair admitted that the risks may be more serious than previously thought.

 TWENTY FIRST SESSION OF THE IPCC   (Site not responding. Last check: 2007-10-10)
IPCC as a body has always been working on the interface of science and policy making and is required to provide scientific, technical and socio-economic information on policy relevant issues.
The IPCC noted that a Technical Paper would be repetitive with the very limited material covered in the IPCC TAR and it was decided to develop a Special Report on this topic.
The IPCC is aware of the valuable input, which is provided through these other programmes, and is looking forward to a continued fruitful cooperation with the other WMO sponsored climate programmes.

 Intergovernmental Panel on Climate Change - Wikipedia, the free encyclopedia
IPCC reports should be neutral with respect to policy, although they may need to deal objectively with scientific, technical and socio-economic factors relevant to the application of particular policies.
The IPCC concentrates its activities on the tasks allotted to it by the relevant WMO Executive Council and UNEP Governing Council resolutions and decisions as well as on actions in support of the UN Framework Convention on Climate Change process.
Authors for the IPCC reports are chosen from a list of researchers prepared by governments, and participating organisations and the Working Group/Task Force Bureaux, and other experts as appropriate, known through their publications and works ([12], 4.2.1,2).

 The IPCC Assessment Process
The Intergovernmental Panel on Climate Change (IPCC) was established in 1988 under the auspices of the United Nations Environment Programme and the World Meteorological Organization for the purpose of assessing "the scientific, technical and socioeconomic information relevant for the understanding of the risk of human-induced climate change.
It is important to note that although the IPCC is organized within a political institutional framework, it is fundamentally a scientific body—made up and led by leading scientists from around the world.
Because the assessments of the IPCC are the most comprehensive and balanced evaluations of the climate change issue, however, its work is probably the single most important foundation on which climate policy is built [2].

 IPCC: Climate Change Impacts
For the range of scenarios developed for IPCC assessment (assuming no major reduction in greenhouse gas emissions), climate models project the Earth to warm 1.4-5.8 degrees Celsius between 1990 and 2100.
While dependent on many factors besides climate change, IPCC experts expect that even for only a small degree of warming, more people would be harmed than benefited by climate change.
IPCC experts conclude, "[p]olicies that lessen pressures on resources, improve management of environmental risks, and increase the welfare of the poorest members of society can simultaneously advance sustainable development and equity, enhance adaptive capacity, and reduce vulnerability to climate and other stresses."

Part of the strength of the IPCC process are the mutliple stages of review - the report is already significantly improved (in clarity and scientific basis) from the first round of reviews, and one can anticipate further improvements from the ongoing round as well.
The next IPCC report (Assessment Report 4, or AR4) is due in 2007, and in order to update of the state of knowledge it will only consider papers published in peer-review scientific journals between 2000 and papers submitted by May 1st 2005 (must be accepted before December 2005).
This is the first of two pieces on the recent IPCC workshop in Hawaii, This brought together independent researchers from all over the world to analyse computer model simulations of the last 150 years and to assess whether they are actually any good.

 Climate Audit - by Steve McIntyre » IPCC   (Site not responding. Last check: 2007-10-10)
IPCC 1AR (1990) noted evidence for worldwide warmth in the mid-Holocene and cited extended glaciers in the recent past in nearly all alpine areas of the world as evidence for a Little Ice Age, citing the text Grove 1989.
The importance of these findings for IPCC was that IPCC 1990 had said that as long as it was unable to explain past larger warmings, it was unable to allocate a proportion of modern warming to human versus natural causes.
If you recall from IPCC 1990, it left an important oustanding question as to the impossibility of attributing the portion of present warming that it is due to human influences, when the attribution of past warmings of equal or greater size was not understood.

 Jean-Marc Jancovici : climate change - what is the IPCC ?
It's the general assembly that sets up the working programme that the IPCC will follow later on, that is the subjects for which it will have to conduct a reviewing process of the available scientific knowledge, and it is the assembly that approves the most important reports, called "assessment reports", before publication.
The documents produced by the IPCC are used as a reference in the international negociations on greenhouse gases, but, in order to avoid any confusion, the IPCC has no official representative at these negociations.
The official publications of the IPCC have for sole purpose to offer a synthesis of the scientific state of the art, what includes both points that are considered well established and points that are still considered (very) speculative by the authors, without forgetting the limits within which the exposed results are valid.
