Prof. Roger A. Pielke Sr seems to be one of the few scientists who raise his voice if an incomprehensible scientific terminology is used that may lead to serious confusion or misunderstanding. In a contribution to SCITIZEN in April 2007[1], he addressed the confusion between the terms ‘global warming’ and…

The UNFCCC (United Nations Framework Convention on Climate Change) is based on missing, or weak and misleading terminology. To understand why, a brief look back on how the text of the Convention had been processed by the assigned Intergovernmental Negotiating Committee (INC) may help to understand its shortcomings better. As…

The Climate Change Convention of the United Nations (UNFCCC) has been of interest to Prof. D. Bodansky from the very start of the negotiation process in 1991, until the completion of the Convention. In 2001 he presented two papers in the book “International Relations and Global Climate Change” [1], which…

Text from 1994 The opportunity to carry out the industrialization of the earth in harmony with the preservation of the climate system has been missed for over a hundred years. Even now it is not recognized that the climate and the sea are a synchronous entity. Instead, there is already…

Roger A. Pielke Sr Research Group Weblog[1] started in July 2005 A great weblog closed down after two years in operation. Roger A. Pielke Sr. was highly praised for his objectivity, tenacity and patience [2]. ‘Whatisclimate.com’ fully endorse the appraisal. Because ‘Whatisclimate’ regards necessary to press for clarification: What is…

Has climate research made any substantial progress since the debate in the 1970’s as to whether the world would slide into global warming or global cooling? One can doubt that if one takes Leonardo da Vinci’s (1452–1519) assessment seriously: Water is the driver of nature. No! …

Let’s face it. The word climate has managed to become the most magical common term in modern time. The word has a several thousand year’s history, but during the last few decades science uses it as ‘it fits best’ to underline the impression of competence, and in a similar way…

Climate is a layman’s term since ever. Science uses the word, but is reluctant to define it a proper academic matter. The UNFCCC United Nation Framework Convention on Climate Change (1992) either avoids clarifying what ‘climate’ stands for. …

If one wants to put a definite date as to when the study of atmospheric processes began to become a science, it was the main explosion of the Krakatoa volcano in August 1883 in the Indonesian archipelago. If you now look at three recently published essays on “volcanic effects on…
