Lee Hannah

Lee Hannah is a conservation ecologist and a Senior Fellow in Climate Change Biology at Conservation International’s Center for Applied Biodiversity Science. Hannah is one of many authors who published an article predicting that by 2050, between 15% and 37% of species will become extinct (6) .

Biography

Lee Hannah received his B.A. in Biology with High Honors in June 1978 from the University of California at Berkeley. His honors thesis was “Renewable Energy: Systems and Implications.” He received his M.S. in Physiology in June 1980 from the University of Hawaii John A. Burns School of Medicine. Hannah received his Doctorate in Environmental Science and Engineering from UCLA in June 1985. His dissertation was “Protection of Hawaii’s Native Birds in Geothermal Energy Development,” with his major advisor being Richard Perrine (2). Since 2000, Hannah has been a Senior Fellow in Climate Change Biology at Conservation International’s (CI) Center for Applied Biodiversity Science (CABS). Since 2004, he has also been working as a visiting researcher and adjunct associate professor at Bren School of Environmental Science and Management at the University of California at Santa Barbara. His classes include Climate Change Biology, Landscape Ecology, and Conservation Planning (2). Hannah is also collaborating with the National Botanical Institutes at Kirstenborsch (in Cape Town) to study biodiversity changes as a result of global warming (4).

Hannah is involved in four societies, the American Association for the Advancement of Science (AAAS), the Ecological Society of America, National Geographic Society, and the Society for Conservation Biology. He holds many honors and awards, including being a National Merit Scholar in 1974; Environmental Science and Engineering Class President in UCLA from 1981-82; the American Institute of Biological Sciences Congressional Fellow in Washington D.C. from 1986-87; and the American Association for the Advancement of Science, a Science and Diplomacy Fellow, in Washington D.C. from 1987-89.

Work

Hannah’s work is primarily centered on how climate change affects biodiversity. He uses that research to see how climate change is affecting conservation efforts. Because of his work, he infers climate change needs to be strongly considered when planning conservation. Lee Hannah strongly supports creating protected areas such as parks and reserves. He is also an advocate of habitat corridors and believes they are necessary for the survival of animals (3). Hannah argues that each species have a certain tolerable range of temperature that they can handle. If a certain area that once was hospitable to the species becomes too hot, the species will migrate to a cooler area. Thus, habitat corridors are needed so animals will be able to make their migrations (4). Finally, Hannah supports lowering greenhouse gas emissions (4).

One of Hannah’s most notable publications was in the January 2004 edition of Nature. In the article, Extinction risk from climate change, Hannah and his coauthors attempt to predict how biodiversity will be affected by climate change (6). The study was done purely by computer simulations and based on the ecological law of the species-area curve, which amounts to the bigger the piece of livable land, the more species that are on it (7). It predicted that the change in climate will cause the earth to heat up. Most areas will become too hot to live, so most organisms will travel up in altitude where it will be cooler. In these few hospitable and high-altitude spaces left, there will be intense competition (7). As a result of climate changes that will take place from now till 2050, between 15% and 37% of species will be on a path to extinction (6). Thus, all of those species will not be extinct by 2050, but extinction will be inevitable for them. Likewise, the study is based on the assumption that climate change will continue at its current pace. If climate change starts leveling-off, it would affect the conclusions of the study (7). Critics of the study point to the all-computer simulation, saying too many unknowns in computers give skewed results. Likewise, some believe that just because living area shrinks, it is not necessarily indicative of the exact number of species that will go extinct (7). These critics point to the fact that plants and animals are able to adapt, and though there will be an impact on life, there will not be as great an impact as this study predicts (7).

Hannah also co-edited a defining book with Thomas Lovejoy on climate change, Climate Change and Biodiversity. It was honored by Choice magazine as one of the “Outstanding Academic Titles” in 2005. It is written to cater to both specialists and those not in the scientific field. It is separated into six parts: Introduction, Present Changes, Learning From the Past, Understanding the Future, Conservation Responses, and Policy Responses (5)
