Some commentators claim that the oil market has achieved within a few months what international bureaucrats have struggled to obtain in a decade of international climate negotiations. The fallacy of the oil price argument is that substitutions and income e ...
Precise information on the relative timing of north-south climate variations is a key to resolving questions concerning the mechanisms that force and couple climate changes between the hemispheres. We present a new composite record made from five well-reso ...
This paper analyzes the proportion of snowfall days relative to precipitation days, in order to assess the impact of changing temperatures on snowfall, while minimizing the impact of variations in precipitation frequency and intensity. We analyzed the rati ...
A numerical model to compute the dynamics of glaciers is presented. Ice damage due to cracks or crevasses can be taken into account whenever needed. This model allows simulations of the past and future retreat of glaciers, the calving process or the break- ...
Catalase and methaemoglobin have very similar haem groups, which are both ferric, yet catalase decomposes hydrogen peroxide to water and oxygen very efficiently, while methaemoglobin does not. Structural studies have attributed this behaviour to their diff ...
Multi-objective optimisation methodology is ideally suited to incorporate environmental objectives in the optimal design of energy conversion systems. It is also desirable to optimise life-cycle emissions rather than local emissions only. However, using LC ...
Web 2.0 portals have made content generation easier than ever with millions of users contributing news stories in form of posts in weblogs or short textual snippets as in Twitter. Efficient and effective filtering solutions are key to allow users stay tune ...
How is vulnerability to climate change spatially distributed? Which are its causes and its effects? Which are the major climate change vulnerability hotspots in which the implementation of adaptation ...
A central issue in climate dynamics is to understand how the Northern and Southern hemispheres are coupled during climate events. The strongest of the fast temperature changes observed in Greenland (so-called Dansgaard- Oeschger events) during the last gla ...
The storage of 'cold' with ice slurries-a special type of thermally multi-functional fluids or phase change slurries (PCS)-is discussed. At first an example of a calculation of a thermal energy storage tank in an ice slurry system with a peak load demand i ...
