Studies have documented climate change–induced shifts in species distributions but uncertainties associated with data and methods are typically unexplored. We reviewed 240 reports of climate-related species-range shifts and classified them based on three criteria. We ask whether observed distributional shifts are compared against random expectations, whether multicausal factors are examined on equal footing, and whether studies provide sufficient documentation to enable replication. We found that only ~12.1% of studies compare distributional shifts across multiple directions, ~1.6% distinguish observed patterns from random expectations, and ~19.66% examine multicausal factors. Last, ~75.5% of studies report sufficient data and results to allow replication. We show that despite gradual improvements over time, there is scope for raising standards in data and methods within reports of climate-change induced shifts in species distribution. Accurate reporting is important because policy responses depend on them. Flawed assessments can fuel criticism and divert scarce resources for biodiversity to competing priorities.

Over Time

Interactions between plants and microbes have important influences on evolutionary processes, population dynamics, community structure, and ecosystem function. We review the literature to document how climate change may disrupt these ecological interactions and develop a conceptual framework to integrate the pathways of plant-microbe responses to climate over different scales in space and time. We then create a blueprint to aid generalization that categorizes climate effects into changes in the context dependency of plant-microbe pairs, temporal mismatches and altered feedbacks over time, or spatial mismatches that accompany species range shifts. We pair a new graphical model of how plant-microbe interactions influence resistance to climate change with a statistical approach to predictthe consequences of increasing variability in climate. Finally, we suggest pathways through which plant-microbe interactions can affect resilience during recovery from climate disruption. Throughout, we take a forward-looking perspective, highlighting knowledge gaps and directions for future research.

Standardized Protocol

Climate change and other global change drivers threaten plant diversity in mountains worldwide. A widely documented response to such environmental modifications is for plant species to change their elevational ranges. Range shifts are often idiosyncratic and difficult to generalize, partly due to variation in sampling methods. There is thus a need for a standardized monitoring strategy that can be applied across mountain regions to assess distribution changes and community turnover of native and non-native plant species over space and time. Here, we present a conceptually intuitive and standardized protocol developed by the Mountain Invasion Research Network (MIREN) to systematically quantify global patterns of native and non-native species distributions along elevation gradients and shifts arising from interactive effects of climate change and human disturbance. Usually repeated every five years, surveys consist of 20 sample sites located at equal elevation increments along three replicate roads per sampling region. At each site, three plots extend from the side of a mountain road into surrounding natural vegetation. The protocol has been successfully used in 18 regions worldwide from 2007 to present. Analyses of one point in time already generated some salient results, and revealed region-specific elevational patterns of native plant species richness, but a globally consistent elevational decline in non-native species richness. Non-native plants were also more abundant directly adjacent to road edges, suggesting that disturbed roadsides serve as a vector for invasions into mountains. From the upcoming analyses of time series even more exciting results especially about range shifts can be expected. Implementing the protocol in more mountain regions globally would help to generate a more complete picture of how global change alters species distributions. This would inform conservation policy in mountain ecosystems, where some conservation policies remain poorly implemented.

Over Time

Assumptions that local communities have an endogenous capacity to adapt to climate change stemming from time-tested knowledge and an inherent sense of community that prompts mobilisation are becoming increasingly common in material produced by international organisations. This discourse, which relies on ahistorical and apolitical conceptions of localities and populations, is based on ideas of timeless knowledge and places. Analysing the water-place nexus in Ladakh, in the Indian Himalayas, through a close study of glacier practices as they change over time, the article argues that local knowledge is subject to change and must be analysed in light of changing conceptions and experiences of place by the state and by local populations alike.

Addressing climate change requires coordinated policy responses that incorporate the needs of the most impacted populations. Yet even communities that are greatly concerned about climate change may remain on the sidelines. We examine what stymies some citizens’ mobilization in Kenya, a country with a long history of environmental activism and high vulnerability to climate change. We foreground efficacy—a belief that one’s actions can create change—as a critical link transforming concern into action. However, that link is often missing for marginalized ethnic, socioeconomic, and religious groups. Analyzing interviews, focus groups, and survey data, we find that Muslims express much lower efficacy to address climate change than other religious groups; the gap cannot be explained by differences in science beliefs, issue concern, ethnicity, or demographics. Instead, we attribute it to understandings of marginalization vis-à-vis the Kenyan state—understandings socialized within the local institutions of Muslim communities affected by state repression.

AbstractCities around the world are confronted with the need to put in place climate adaptation policies to protect citizens and properties from climate change impacts. This article applies components of the framework developed by Moser and Ekström (2010) onto empirical qualitative data to diagnose institutional barriers to climate change adaptation in the Municipality of Beirut, Lebanon. Our approach reveals the presence of two vicious cycles influencing each other. In the first cycle, the root cause barrier is major political interference generating competing priorities and poor individual interest in climate change. A second vicious cycle is derived from feedbacks caused by the first and leading to the absence of a dedicated department where sector specific climate risk information is gathered and shared with other departments, limited knowledge and scientific understanding, as well as a distorted framing or vision, where climate change is considered unrelated to other issues and is to be dealt with at higher levels of government. The article also highlights the need to analyze interlinkages between barriers in order to suggest how to overcome them. The most common way to overcome barriers according to interviewees is through national and international support followed by the creation of a data bank. These opportunities could be explored by national and international policy-makers to break the deadlock in Beirut.
