Living with anthropogenic climate change: Learning from environmental history to question narratives of doom,hope, and crisis

We are living with anthropogenic climate change and must address the causes and reduce the negative impacts on our planet, humans, and other species. This commentary offers a brief review of environmental history from deep time to recent waves of environmentalism demonstrating that climate change has occurred before; that people have faced perceived end times; and that predictions of doom have helped us to act to avoid that potential scenario. These are important lessons for how we may live today and into the future, given the shift from climate change denial to narratives of impending doom because we have already failed to act. The commentary presents a matrix of positions adopted in relation to climate change and environmentalism more generally, highlighting narratives of hope, doom, and urgency. While not exhaustive, these summarised positions alert us to possibilities and are intended to generate wider discussion about how we may live with anthropogenic climate change. We have to learn to live with anthropogenic climate change while addressing the causes and reducing the negative impacts on our planet, humans and on other species.     

Understanding ethnic differences in perceptions,attitudes, and behaviours: a study of domestic water use in Sydney

There is growing realisation among environmental and social studies researchers that people's decision‐making about water use conforms to their internal norms and beliefs, which are developed in social and cultural contexts. Little research, however, has addressed the possible impacts that ethnic and cultural diversity may have on domestic water use and management. This paper presents the results of a study conducted in Sydney, with specific reference to questionnaire findings. Among respondents from different ethnic and cultural backgrounds, significant differences were observed in terms of perceptions, specific knowledge, attitudes, and self‐reported behaviours in relation to water use and conservation. The disparities identified were not masking socio‐demographic and economic characteristics but were the result of a series of constructs closely tied to ethnicity, including cultural value, environmental experience, language preference, and information access. As a factor explaining variation in the engagement of pro‐conservation behaviour, ethnic status was found to be more useful than some socio‐economic factors. The study highlights the importance of including ethnicity and cultural sensitivity issues in the decision‐making process of environmental management.     

Palynology and archaeological inference: bridging the gap between pollen washes and past behavior

Credible interpretation of pollen recovered from archaeological sites hinges upon understanding how pollen becomes deposited by both the environment and human behavior. The environmental role has been studied to some extent, but how the activities of people have formed the pollen assemblages at archaeological sites is usually just assumed rather than considered explicitly. Moreover, the complexity involved in the interaction between human behavior and pollen ecology is seldom considered. An archaeological case study of grinding tool pollen washes highlights the ambiguities of standard practice because the results confound common assumptions about pollen washes. A series of experimental seed and grinding tool washes designed to test the relationships between the processing of seeds and the deposition of pollen help explain why, for most situations, artifact pollen washes do not provide direct or even faithful records of plant processing. These results highlight the need for further experimental research with pollen so that we are warranted in making behavioral inferences from palynology. This conclusion is easily extended to other microbotanical data classes that archaeologists regularly employ.
