Abstract Recent surveys of the literature on climate change and migration emphasize the important diversity of outcomes and approaches of the empirical studies. In this paper, we conduct a meta-analysis in order to investigate the role of the methodological choices of these empirical studies in finding some particular results concerning the role of climatic factors as drivers of human mobility. We code 51 papers representative of the literature in terms of methodological approaches. This results in the coding of more than 85 variables capturing the methodology of the main dimensions of the analysis at the regression level. These dimensions include authors' reputation, type of mobility, measures of mobility, type of data, context of the study, econometric methods, and last but not least measures of the climatic factors. We look at the influence of these characteristics on the probability of finding any effect of climate change, a displacement effect, an increase in immobility, and evidence in favor of a direct vs. an indirect effect. Our results highlight the role of some important methodological choices, such as the frequency of the data on mobility, the level of development, the measures of human mobility and of the climatic factors as well as the econometric methodology.

AbstractTakotsubo syndrome (TTS) is an acute heart failure syndrome with significant rates of in and out-of-hospital mayor cardiac adverse events (MACE). To evaluate the possible role of neoplastic biomarkers [CA-15.3, CA-19.9 and Carcinoembryonic Antigen (CEA)] as prognostic marker at short- and long-term follow-up in subjects with TTS. Ninety consecutive subjects with TTS were enrolled and followed for a median of 3 years. Circulating levels of CA-15.3, CA-19.9 and CEA were evaluated at admission, after 72 h and at discharge. Incidence of MACE during hospitalization and follow-up were recorded. Forty-three (46%) patients experienced MACE during hospitalization. These patients had increased admission levels of CEA (4.3 ± 6.2 vs. 2.2 ± 1.5 ng/mL, p = 0.03). CEA levels were higher in subjects with in-hospital MACE. At long term follow-up, CEA and CA-19.9 levels were associated with increased risk of death (log rank p < 0.01, HR = 5.3, 95% CI 1.9–14.8, HR = 7.8 95% CI 2.4–25.1, respectively, p < 0.01). At multivariable analysis levels higher than median of CEA, CA-19.9 or both were independent predictors of death at long term (Log-Rank p < 0.01). Having both CEA and CA-19.9 levels above median (> 2 ng/mL, > 8 UI/mL respectively) was associated with an increased risk of mortality of 11.8 (95% CI 2.6–52.5, p = 0.001) at follow up. Increased CEA and CA-19.9 serum levels are associated with higher risk of death at long-term follow up in patients with TTS. CEA serum levels are correlated with in-hospital MACE.

The relative importance of ancient demography and climate in determining worldwide patterns of human within-population phenotypic diversity is still open to debate. Several morphometric traits have been argued to be under selection by climatic factors, but it is unclear whether climate affects the global decline in morphological diversity with increasing geographical distance from sub-Saharan Africa. Using a large database of male and female skull measurements, we apply an explicit framework to quantify the relative role of climate and distance from Africa. We show that distance from sub-Saharan Africa is the sole determinant of human within-population phenotypic diversity, while climate plays no role. By selecting the most informative set of traits, it was possible to explain over half of the worldwide variation in phenotypic diversity. These results mirror those previously obtained for genetic markers and show that ‘bones and molecules’ are in perfect agreement for humans.

Stress Cardiac Magnetic Resonance

Takotsubo syndrome is an acute, profound but reversible heart failure syndrome of unknown aetiology, usually but not always triggered by physical or emotional stress. Cardiac magnetic resonance has become an important tool for the non-invasive assessment of the syndrome, allowing for a comprehensive, safe and reproducible assessment of functional and anatomical myocardial properties, including perfusion, oedema and necrosis. This review focuses on the emerging role of cardiac magnetic resonance for the characterisation, differential diagnosis as well as risk stratification of patients with Takotsubo syndrome.

The Creation

Two climatically different areas on granitic materials near Phalaborwa and Pretoriuskop in the Kruger National Park were pedogeomorphologically compared and the influence of climatic factors on soil and hillslope development in the two areas was assessed. The examination of 18 hillslopes and their soils showed that while the two areas have many broad similarities, there are specific soil and hillslope differences between them with the result that each area has its own distinctive pedogeomorphic character. While comparable parent material, situation and age appear to be responsible for similarities between the areas, the differences could in most cases be accounted for by the disparity in rainfall between the two areas. It was, however, also necessary to note the role of past (and possibly current) cycles of erosion and deposition in the creation of the two types of simple hillslopes occurring in the areas.

Mountain communities are adapting their livelihoods to a complex combination of social, political and economic changes and associated risks. Despite recognition of adaption in response to multiple changes in sustainable livelihood and critical climate change literature, risks attributed to biophysical effects of climate change have increasingly assumed importance. Consequently, diversification is promoted as an adaptive approach to reduce such risks. However, understanding livelihood adaptation from the vantage point of climate change alone might lead to a limited understanding of non-climatic factors also shaping it. This paper proposes understanding adaptation through analysing long-term livelihood changes and using society rather than climate change as a conceptual starting point. It argues that such an approach has better potential to highlight a broader range of dynamic drivers operating over decades and to inform contextually grounded rural livelihood adaptation policies. Changes are traced in the overall livelihood trajectories among four rural communities in Nepal, in living memory, to understand the role of adaptation in shaping it. Qualitative life narratives were collected and complemented by key informant interviews, field observations and the analysis of official documents. The findings suggest that livelihoods have shifted not only from subsistence towards income generation but also from engagement in diverse livelihood sectors towards specialisation; the opposite of the advocated diversification. The role of political, economic, social and cultural processes within and outside the community has been prominent in shaping this trajectory.
