The effects of climate change on agricultural productivity are influenced by a range of factors including changes in temperature, precipitation, humidity, and frost and carbon fertilisation. Recent literature on the sensitivity of the agriculture sector to climate change highlights the need for understanding the way climate change influences the distribution of productivity impacts. These impac...

Introduction Peer assessment is utilized extensively in digital learning, and many studies have examined the positive influences of online peer assessment on learning (eg, Tseng & Tsai, 2007). However, other studies indicate that this type of activity has negative influences. For example, students may question the fairness of an assessment or disagree with others’ assessments (eg, Kaufman & Sch...

A frequently cited atmospheric CO2 threshold for the onset of Antarctic glaciation of ∼ 780 ppmv is based on the study of DeConto and Pollard (2003) using an ice sheet model and the GENESIS climate model. Proxy records suggest that atmospheric CO2 concentrations passed through this threshold across the Eocene–Oligocene transition ∼ 34 Ma. However, atmospheric CO2 concentrations may have been cl...

Adolescents, especially females, have been identified as a group at risk of poor health due to their declining level of physical activity.

The UK government’s recent Climate Change Bill set an ambitious target of an 80% reduction in emissions by 2050. This level of response to climate change has profound implications for individual choices and behaviour, as well as for the social structures in which these operate. With over one third of many nations’ carbon emissions coming from private travel and domestic energy use, individuals ...
