Quote:Daniel B. Botkin, a world-renowned ecologist, is Professor (Emeritus), Department of Ecology, Evolution and Marine Biology, UC Santa Barbara, and President of The Center for The Study of The Environment, which provides independent, science-based analyses of complex environmental issues. The New York Times said his book, *Discordant Harmonies: A New Ecology for the 21st Century* is considered by many ecologists to be the classic text of the [environmental] movement.” His Environmental Science, now in its Sixth Edition, was named 2004′s best textbook by the Textbook and Academic Authors Association.”

Since 1968 I have published research on theoretical global warming, its potential ecological effects, and the implications for people and biodiversity. I have spent my career trying to help conserve our environment and its great diversity of species. In doing so I have always attempted to maintain an objective, intellectually honest, scientific approach in the best tradition of scientific endeavor. I have, accordingly, been dismayed and disappointed in recent years that this subject has been converted into a political and ideological debate. I have colleagues on both sides of the debate and believe we should work together as scientists instead of arguing divisively about preconceived, emotionally based “positions.” I hope my testifying here will help lead to a calmer, more rational approach to dealing with not only climate change but also other major environmental problems. The IPCC 2014 report does not have this kind of rational discussion we should be having. I would like to tell you why.

The IPCC 2014 report is actually a series of reports, each long, complex in organization, and extensive in scope. Since it’s not possible to discuss the Summary Reports for Policymakers in detail today, I will highlight some of my thoughts for you here as they relate to the reports, hoping to bring a saner, more sober approach to this highly charged issue.

To characterize where we are with this report and this issue, I would like to quote James R. Schlesinger, the first U.S. Energy Secretary, who said: “We have only two modes — complacency and panic.”—commenting on the country’s approach to energy (1977)

Now to my major points.

1. I want to state up front that we have been living through a warming trend driven by a variety of influences. However, it is my view that this is not unusual, and contrary to the characterizations by the IPCC and the National Climate Assessment, these environmental changes are not apocalyptic nor irreversible.

2. My biggest concern is that both the reports present a number of speculative, and sometimes incomplete, conclusions embedded in language that gives them more scientific heft than they deserve. The reports are “scientific-sounding” rather than based on clearly settled facts or admitting their lack. Established facts about the global environment exist less often in science than laymen usually think.
