Communicating the Science and Human Significance of Climate Change

by Ellen Broaddus

Seidler and Stevenson (2017) review two books dealing with the psychological factors that impact the personal and societal undervaluing of humanity’s role in causing climate change and its effects on them. They stress that this is not a new issue: even in 1988 the Intergovernmental Panel on Climate Change (IPCC) emphasized the need for a systemic change in energy production and consumption. Almost 30 years later, CO2 emissions have more than doubled, and it is still unclear whether current efforts such as the Paris Conference (COP) will lead to meaningful action.

The two books, What We Think About When We Try Not to Think about Global Warming and Stolen Future, Broken Present: The Human Significance of Climate Change suggest that our inaction is caused not by a data gap or lack of understanding of the risks but our “psychic habits, social dynamics, and ethical quirks”. In the first book, author Stoknes discussed the need for effective marketing. While studies show that “scary” emotional marketing tactic is successful among almost all audiences, Stoknes poses some important questions about the role of marketing and persuasion: is the societal denial of climate change a result of too few messages? What is the balance between sufficient advertisement and evoking denial and rationalization? Are we presenting enough range of marketing tactics to engage everyone? Continue reading

The Climate Change Challenge and Barriers to the Exercise of Foresight Intelligence

by Ellen Broaddus

In Ross et al. (2016), experts from various academic fields assess some of the barriers that aid today’s denial and inaction combating climate change, even with overwhelming evidence from the scientific community. This hesitancy is traced back to a combination of cognitive shortcomings and the difficulty to work collectively on an issue so complex and seemingly indirect. However, the authors provide examples of strategies used to combat said inaction and their efficacy.    Continue reading

Past Polar Ice-Sheet Mass Loss Contributes to Sea-Level Rise

by Grace Stewart

Understanding of global mean sea level during past interglacial periods has greatly improved, but many challenges remain. By using coastal records and oxygen-18 proxy data, Dutton et al. (2015) determined global mean sea level and the contribution from polar ice sheets during three past interglacial periods. Although the results were uncertain, it was determined that global mean sea level was higher than modern day levels in every interglacial period studied—the mid-Pliocene warm period 3,000,000 years ago, the marine isotope stage (MIS) 11 400,000 years ago, and MIS 5e 125,000 years ago. Previous findings were corrected by taking glacial isostatic adjustment (the adjustment of the earth for a long time after a period of deglaciation), dynamic topography, and ice sheet reconstructions into account.
