These two books draw attention to the role of Canada's oil-producing provinces—“petro-provinces” for Angela Carter and “carbon provinces” for Douglas Macdonald—in the politics of energy, environment and climate change, but they do so in very different ways. Carter's volume examines the erosion of environmental protections in the oil-rich provinces of Alberta, Saskatchewan, and Newfoundland and Labrador, while Macdonald's focuses on the way interest-based conflicts rooted in regional energy political economies have driven federal/provincial dynamics around energy and climate policy. Both books are well written (not always a given in academic publishing), and they should interest anyone concerned with the politics of energy, environment and climate change in Canada.

Climate change will impact several ecosystems, and the resilience of the weakest links of the ecological networks may be decisive in maintaining the ecological structure. The assessment of tendencies in the distribution and resilience of endangered medicinal species against global change can be an excellent tool to predict and minimize future negative effects, even more so if we consider that these species may be useful to us. Spain is one of the richest countries in plant diversity along the Mediterranean basin, and many representatives of the Spanish flora are medicinal plants. Under scenarios of climate change, the distribution ranges of many of these species are likely to alter. In this paper we used ecological niche modeling to predict future changes in the distribution of 41 medicinal plants included in the 2013 assessment of threatened species in Spain. We generated climate-based niche models for each medicinal species and projected them for each decade from 2010 until 2080. Our results identified and prioritized the most vulnerable species and areas to future predicted changes. These results should be useful for conservation planning and especially for prioritizing areas for protection.

O Ozônio troposférico é um poluente secundário que se forma a partir da quebra de óxidos de nitrogênio pela ação da radiação solar e da presença de compostos orgânicos voláteis na atmosfera. Analisaram-se tendências para o ozônio troposférico e para o dióxido de nitrogênio através de dez anos de dados horários em dois locais distintos da cidade de Curitiba, região sul do Brasil. Em ambos os pontos, observou-se uma forte tendência ao crescimento do O3 e um decréscimo nos níveis de NO2. A hipótese aqui defendida indica que o crescimento do O3 observado em Curitiba, não acompanhado pelo NO2 seria uma repercussão de alterações na dinâmica climática da região, credenciando-o como um desafio neste novo século. Palavras-chave: Mudanças Climáticas, Curitiba, ozônio troposférico  Abstract The tropospheric ozon it’s a secundary pollutant that is formed by the separation of nitrogen oxydes due to the action of solar radiation and the presence of volátil organic compounds in the atmosphere. Future trends for tropospheric ozone and dioxide nitrogen were analyzed throught ten years of hourly data in two diferent points of Curitiba, South region of Brazil. In both of then, a strong growing trend of O3 and a decrease on the NO2 were observed. The hypothesis defended here is that the increase of O3 observed in Curitiba, not followed by the NO2 would be a repercusion of a change on the climate dinamic of the region, accrediting it as a challenge of this new century. Keywords: Climate Change, Curitiba, tropospheric ozon.
