 Background

Craig Loehle is the principal scientist with the National Council for Air and Stream Improvement, which was established in 1943 by the pulp and paper industry to “provide technical assistance for the industry’s goal of lowering the ecological impact of its spent pulping liquors.” [2]

Loehle worked in the Environmental Research Division at Argonne National Laboratory 1991-1998 and was a Research Ecologist at Savannah River Laboratory from 1987-1991

Stance on Climate Change

“I am not a 'denialist' and my recent paper… attributes about 40% of recent warming to human activity – estimating that this equates to a no-feedback atmosphere.

“What I would deny is that tree rings are good thermometers, but this is a scientific view based on my knowledge of trees, not a political view.” [3]

Key Quotes

“The climate change “biodiversity crisis” is like a whack-a-mole game (a carnival game where plastic animals pop out of holes and you try to whack them with a mallet), with an almost-daily claim popping up about this species or that at risk from climate change. Not just polar bears and coral reefs, but even avocados are going to disappear! Whacking each silly claim one by one is an impossible task, and the claims get into public consciousness whereas the refutations do not.” [10]

“I am not part of a conspiracy and am not directed by anyone. I have never received money from fossil fuel interests, as Mann states is true of all sceptics. On the contrary, I work for the US wood products industry (which has no official position on climate change and does not tell me what to say or think). This industry is the largest single renewable fuels user because it uses wood waste to generate steam and power at paper mills. It is also the largest recycler (of paper), plants millions of trees every year, and manages millions of acres of forest land to ensure protection of wildlife. Only a fraction of my work concerns climate change.” [3]

“Within the United States, the claim that bad climate effects can 'already' be detected is a totally subjective and unsupported hypothetical.” [4]

Key Deeds

July 7 - 9, 2014

Craig Loehle was a speaker at the Heartland Institute’s Ninth International Conference on Climate Change (ICCC9) in Las Vegas, Nevada. [11]

DeSmogBlog has done in-depth research on the other speakers and sponsors from Heartland's ICCC9, which can be found here.

May, 2012

Craig Loehle was a speaker at the Heartland Institute's Seventh International Conference on Climate Change (ICCC7).

DeSmogBlog researched the co-sponsors behind Heartland's ICCC7 and found that they had collectively received over $67 million from ExxonMobil, the Koch Brothers and the conservative Scaife family foundations.

2011

Co-authored a study (PDF) with fellow climate change skeptic Nicola Scafetta. The study, titled “Climate Change Attribution Using Empirical Decomposition of Climatic Data,” contends that “current models underestimate the strength of natural multidecadal cycles in the temperature records, the anthropogenic contribution to climate change since 1850 should be less than half of that previously claimed by the IPCC.” [5]

March 8 - 10, 2009

Loehle was a speaker at the Heartland Institute's 2009 International Conference on Climate Change (ICCC2).

His presentation was titled “1,500-Year Climate Cycles, Broken Hockey Sticks, and Ocean Cooling.” [6]

DeSmogBlog researched the funding behind Heartland's Second International Conference on Climate Change, and found that sponsor organizations had received over $47 million in funding from energy companies and right-wing foundations, with 78% of that total coming from the Scaife Family of foundations.

2007

Published a paper in Energy & Environment titled “A 2000 Year Global Temperature Reconstruction based on Non-Treering Proxy Data” (PDF) which set out to refute Michael Mann's “Hockey Stick” data.

The original study, which contained numerous issues, was corrected in a subsequent publication. According to RealClimate, the corrected study still contained inappropriate data selection, or the calibration and validation issues. [7]

Loehle commented on the corrected study at Anthony Watts' blog Watts Up With That (WUWT).

 Publications

According to his profile at the Heartland Institute, Loehle has written more than 100 peer-reviewed papers in forestry, ecology, geophysics, modeling, and other fields.

It appears that his only papers related to climate were published in the journal Energy and Environment in 2007 and 2008. The journal commonly publishes the work of climate change skeptics and has been criticized for its peer-review process and publication of sub-standard articles. The current editor of the journal is climate change skeptic Sonja Boehmer-Christiansen.

Aggressively tackling global warming through better public transportation and increased energy efficiencies could increase global GDP by between $1.8 trillion and $2.6 trillion annually, a new report has found.

Released on Monday, the report by the World Bank and the ClimateWorks Foundation said tackling global warming now would also save as many as 94,000 lives a year from pollution-related diseases and reduce crop losses.

The report —...
