The use of digital tracking of individuals throughout the coronavirus 2019 (COVID-19) pandemic renewed societal debates on the efficacy and ethics of digital surveillance to mitigate collective crises. While digital emissions tracking is being used to support climate-mitigation strategies, to date there has been limited exploration of the opportunities and challenges of deploying it at the individual level. Here, we assess temporal and regional differences in levels of support for the use of digital surveillance in times of crisis, such as climate change. Results from a global survey indicate moderate support for the use of digital tracking, including for personal carbon footprints. Response varied regionally, with the lowest support in North America and Europe. This study raises key questions-if digital surveillance tools could be part of a socially acceptable response to the climate crisis, is it worth exploring? Or is this an unacceptable risk for society?

Debates about the likelihood of conspecific care for disabled individuals in ancestral hominins rely on evidence from extant primates, yet little is known about social treatment (positive, neutral or negative) of physically disabled individuals in nonhuman primates. A group of free-ranging Japanese macaques ( Macaca fuscata ) at the Awajishima Monkey Center (AMC) in Japan presents a unique opportunity to investigate the relationships between physical impairment and social behavior, in the context of congenital limb malformation in adult nonhuman primates. We collected behavioral data on 23 focal animals, taking 30-minute continuous time samples on disabled and nondisabled adult female Japanese macaques during three consecutive birth seasons (May–August 2005, 2006, and 2007). Disabled females were less social overall compared with nondisabled controls, a pattern that was evident from a variety of measures. Disabled females rested significantly more and socialized significantly less compared with controls, had fewer adult female affiliates, fewer adult female grooming partners, and spent less time engaged in grooming with adult females. Some measures suggested that the social differences were the result of behavioral flexibility on the part of disabled females compensating for their disabilities with lower levels of social involvement and more rest. Disabled females were as successful at groom solicitations as were nondisabled females and the ratio of disabled and nondisabled affiliates was similar among focal animals; there was no strong preference related to the disability status of affiliates. Disabled females were also bitten and chased less frequently. Overall, there was little evidence either for conspecific care or for social selection against disability. In general, there was a socially neutral response to disability, and while neutral social context allows for the possibility of care behaviors, our findings emphasize the self-reliant abilities of these disabled primates and suggest caution when inferring conspecific care for even very disabled ancestral humans.

With increasing the solar reflectance of urban surfaces, the outflow of short-wave solar radiation increases, less solar heat energy is absorbed leading to lower surface temperatures and reduced outflow of thermal radiation into the atmosphere. This process of “negative radiative forcing” effectively counters global warming. Cool roofs also reduce cooling-energy use in air conditioned buildings and increase comfort in unconditioned buildings; and cool roofs and cool pavements mitigate summer urban heat islands, improving outdoor air quality and comfort. Installing cool roofs and cool pavements in cities worldwide is a compelling win–win–win activity that can be undertaken immediately, outside of international negotiations to cap CO2 emissions. We review the status of cool roof and cool pavements technologies, policies, and programs in the U.S., Europe, and Asia. We propose an international campaign to use solar reflective materials when roofs and pavements are built or resurfaced in temperate and tropical regions.

The National 12th Five-Year-Plan for Social and Economic Development (2011–2015) (national development policy) in China requires knowledge of ecological complexity to better guide policy development for adaptation strategies and mitigation to complex climate change. The thinking of human–environment interactions supplements climate change related policies in supporting sustainability through adaptation and mitigation. Based on a review of the climate change contents of the National 10th and 11th Five-Year-Plan in China, the paper illustrates the complexity of climate changes that have affected China's environmental sustainability now and offers policy viewpoints for the in-preparing 12th Five-Year Plan, with five core areas for the implementation of climate change policy: (A) development of the transition to a low carbon economy, (B) prevention and treatment of urban environmental negative effects caused by climate change, (C) adaptation to sea level rises in coastal zones, (D) maintaining the resilience of natural ecosystems affected by climate change, and (E) prevention and control of climate disaster and environmental risk.
