Global Warming: Human Intervention in World Climate
2010
In the preceding chapter, we described climate changes that have occurred over very long geological periods. We concluded that Earth is currently in an interglacial interval within a rather long period of glaciations. Indeed, average carbon dioxide concentrations in the atmosphere have been slowly decreasing over the past 600,000 years, with accompanying cooling (Fig. 6.3). There have been, of course, many periodic changes in the CO2 concentrations and average temperature over this period (see Fig. 7.1). However, very recently, something quite unique and startling has occurred. As Fig. 7.1 shows, there has been a remarkable increase in CO2 levels, actually during the past 200 years, from 28…
MULTIPLE CLIMATE-DRIVEN CASCADING ECOSYSTEM EFFECTS AFTER THE LOSS OF A FOUNDATION SPECIES
2021
Abstract Climate change is evolving so fast that the related adverse effects on the environment are becoming noticeable. Thus, there is an urgent need to explore and understand the effects generated by multiple extreme climatic events (MECEs) on marine ecosystem functioning and the services provided. Accordingly, we combined long-term in-situ empirical observations in the Mediterranean Sea with a mesocosm manipulation to investigate the concurrence of increasing temperature and hypoxia events. By focussing on a foundation mussel species, we were able to detect several cascade events triggered by a mass mortality event caused by stressful temperature and oxygen conditions, and resulting in a…
Global warming and tourism: chronicles of apocalypse?
2012
PurposeGlobal warming is a huge challenge faced by the mankind in the twenty‐first century and beyond. The paradox of ecology lies in the pervasive attitude of lay people who overtly condemn pollution but do not alter their individual practices. Unfortunately, the scientific community has still not reached unanimous conclusions about the causes or impacts of global warming. To close this gap, the present paper aims to stimulate discussion in two main senses: the relationship between industry and global warming; and the role of tourism in the coming decades.Design/methodology/approachBased on reading and criticism of many works, this paper provides a conceptual framework for readers to under…
