Guardian scribe can’t cope with complex scientific arguments unseating his cognitive faculties: (and wealthy nations de-developed and the wealth transferred to poorer nations of course) “Climate Change is Man Made” and lots of money must change hands to stop it. Which is a messy and incommunicable combination. See also Climate variability Detection and Attribution” The UNFCCC thus makes a distinction between climate change attributable to human activities altering the atmospheric composition, and climate variability attributable to natural causes. Note that the United Nations Framework Convention on Climate Change (UNFCCC), in its Article 1, defines climate change as: ‘a change of climate which is attributed directly or indirectly to human activity that alters the composition ofthe global atmosphere and which is in addition to natural climate variability The composition of the atmosphere or in land use. Climate change may be due to natural internal processes or external forcings, or to persistent anthropogenic changes in “Climate change refers to a change in the state of the climate that can be identified (e.g., by using statistical tests) by changes in the mean and/or the variability of its properties, and that persists for an extended period, typically decades or longer. Which does at least acknowledge uncertainty as to the predominate climate drivers (they don’t know – we do) Climate change may be due to natural internal processes or external forcings, or to persistent anthropogenic changes in the composition of the atmosphere or in land use.” “Climate change refers to a statistically significant variation in either the mean state of the climate or in its variability, persisting for an extended period (typically decades or longer). “a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over a comparable time period”Īnd Is substantially different to (can’t remember where I got this from): The 1992 definition has a biased nuance (they don’t entertain the notion that natural cycles forcings just might be the major climate drivers) : In reality there are several other causes of changes of climate, some by humans, such as urban development, energy emissions, and land use change, and some natural, such as the sun, volcanoes, El Niño ocean changes and cosmic rays, not present in the models, which means that they are all of very limited use.’ It gives the impression that ALL “Changes of Climate” are caused by human emitted greenhouse gases, and encourages the use of climate models that are based on that assumption. This definition has the following unfortunate consequences. The definition is “a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over a comparable time period”. Yes as Dr Gray says ‘There needs to be part of the “Introduction”, or even a separate section, discussing the problems and ambiguities that have been caused by the definition of “Climate Change” in the Framework Convention on Climate Change 1992. International treaty, and you cannot just change it like this.’įor lay people like me the site is certainly educational It is no useĬlaimimg that the IPCC hacve changed this definition. Scientists to study the climate before they have been able to attribute any possible cxause. This is a very restricted definition which makes it impossible for Is defined, legally by the Framework Convention on Climate Change as exclusively concerbed with changes First, you should avoid using the term “climate change” altogether, because it This is one comment I like from his review of Ch 9 ‘Paragrapg 5.1.1. Dr Gray’s bio is also on site and his reviews are certainly worth a read even without comparing them line by line to the report. Which contains extensive material by Malcolm Roberts and John Maclean (their bios are on site) and also reviews of the UN IPCC’s 2007 report by chapter by Dr Vincent Gray (UN IPCC Expert Reviewer,) (PhD chemistry, Cambridge) who has reviewed every UN IPCC Assessment Report and Summary for Policy Makers: 1991, 1995, 2001, 2007.) There is also a link to the 2007 report and its chapters.
