Thinking about climate change: look up and look around!

A Fresh Look at Climate Change

Recently The Economist (2013a), a prominent journalistic advocate of strong policies to control CO2 emissions, expressed their puzzlement on the absence of warming over the last 15 years. They observed that this flat period of global average temperature occurred despite that CO2 emissions from human sources continued at an increased rate. The total human-produced CO2 emissions in that period of...

A Closer Look at Climate Change Skepticism

Looking around to look forward.

Monitoring should be an obsession in the management of mechanically ventilated patients. The control of vital signs and respiratory parameters must guide the ICU professional in responding with precision to the patient’s needs. The setting of mechanical ventilation parameters is a very important issue in the management of a critically ill patient, and the setting of the ideal PEEP level is a pa...

Look up Table Based Low Power Analog Circuit Testing

In this paper, a method of low power analog testing is proposed. In spite of having Oscillation Based Built in Self-Test methodology (OBIST), a look up table based (LUT) low power testing approach has been proposed to find out the faulty circuit and also to sort out the particular fault location in the circuit. In this paper an operational amplifier, which is the basic building block in the ana...

Another Look at Climate Sensitivity

We analyze here a classical energy balance model (EBM) with nonlinear feedbacks and revisit in this context a recent claim that — in a model-independent sense — the climate system may exhibit an asymmetric, large-amplitude response to normally distributed forcing; such a response would imply irreducible uncertainty in climate change predictions. We show that equilibrium climate sensitivity in a...
