Terrestrial warming and cooling: Either or both?

Cooling Flows or Warming Rays?

The radiative cooling time of the X-ray-emitting plasma near the center in many clusters of galaxies is shorter than the age of the cluster, but neither the expected large drop in central temperature –nor the expected mass flow towards the pressure-depleted cluster centers– are observed. We propose a solution to these “cooling flow” problems wherein energy is supplied to the plasma by hadronic ...

Is the climate warming or cooling?

[1] Numerous websites, blogs and articles in the media have claimed that the climate is no longer warming, and is now cooling. Here we show that periods of no trend or even cooling of the globally averaged surface air temperature are found in the last 34 years of the observed record, and in climate model simulations of the 20 and 21 century forced with increasing greenhouse gases. We show that ...

Reference Ontologies - Application Ontologies: Either/Or or Both/And?

The distinction between reference ontologies and application ontologies crept rather unobtrusively into the recent literature on knowledge engineering. A lot of the discourse surrounding this distinction – notably, the one framing the workshop generating this collection of papers – suggests the two types of ontologies are in some sort of opposition to one another. Thus, Borge et al. [3] charact...
