IPCC Studies And Reports Have Nothing to Do with Climate Change
By Dr. Tim Ball Monday, September 20, 2010
Most people have no idea what the Intergovernmental Panel on Climate Change (IPCC) actually studies. They believe their reports are complete reports of climate change. This misconception is mostly because the IPCC arranged it and does little to correct it. In fact, they only look at that portion of climate change caused by humans. Here’s how they limit their study.
“The definition of climate change 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 of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods’. The UNFCCC thus makes a distinction between climate change attributable to human activities altering the atmospheric composition, and climate variability attributable to natural causes.”
The problem is you cannot determine the human portion of climate change if you don’t know how much it changes naturally – and we don’t. The IPCC assumes humans cause most of the changes that are occurring and set out to prove that is true.
Everything they’ve done is contrary to normal scientific practices yet is presented to the public as solid science. The IPCC has done nothing to publicly or formally disavow claims that the science is settled. It is not settled because it never began, or worse, was deliberately diverted.
Explosion of knowledge over the last 200 years forced traditional disciplines to split into increasingly small areas. Academia became more detached from the real world and moved from the broad divisions of natural sciences and humanities in the 19th century through the addition of social sciences in the early 20th century into narrowly defined departments. Within these specialized areas the focus narrowed even more until information was vast, but understanding became further removed from reality. The dictum in academia and society became that to generalize is the mark of foolishness, to specialize the mark of genius.
By the 1970s problems developed as the new approach no longer worked – it didn’t fit society. Academia responded with the growth of inter-disciplinary departments for everything from child development studies to environmental studies. Systems analysis evolved to help interrelate segments of complexities.
Continues with, "Climatology is a generalist discipline in this age of specialization".
