Based on high-resolution models, we investigate the change in climate extremes and impact-relevant indicators over Europe under different levels of global warming. We specifically assess the robustness of the changes and the benefits of limiting warming to 1.5°C instead of 2°C. Compared to 1.5°C world, a further 0.5°C warming results in a robust change of minimum summer temperature indices (mean, Tn10p, and Tn900p) over more than 70% of Europe. Robust changes (more than 0.5°C) in maximum temperature affect smaller areas (usually less than 20%).

Wind power is a near-zero-emissions source of energy. Although at present wind turbines are placed on the Earth’s surface, high-altitude winds offer greater possibilities for power generation. This study uses a climate model to estimate power generation for both surface and high-altitude winds, and finds that the latter provide much more power, but at a possible climate cost. However, there are unlikely to be substantial climate effects in meeting the present global demand.

As long as the present generation of the powerful, whether the rulers in Washington or in New Delhi, persists with the practice of depending on its armed infrastructure to lord over the political space and establish hegemony over civil society, and fails to learn that such a policy invariably escalates a cycle of violence, the language of discourse in the relationship of the powerful and the powerless will be dominated by violence. In India today, how can there be a non-violent resolution of the major confl icts that are plaguing our society?

The communication by Singh et al. on single nucleotide polymorphisms among the Jarawas of the Andaman Islands appears to be a purely academic endeavour. The evident outcome of the study is the discovery of polymorphism in two genes. The authors have not elaborated on the significance of the discovery for the Jarawa populations investigated. It is also difficult to comprehend how any population genetics-based epidemiological study could be undertaken without information on the parent-offspring relationships in the samples.
