Arctic Feedback Dynamics

As a non-scientist, I have found this presentation by David Wasdell of the Apollo-Gaia Project very clear.

He is only talking about a small part of the now 39 positive, self-reinforcing feedbacks

Arctic Feedback Dynamics Presentation by David Wasdell

The Arctic region is currently showing the fastest moving response to global warming and climate change anywhere on the planet. 

This presentation provides a definitive overview of the situation, drawing together the best available resources from a variety of institutions around the world. 

It combines observations with analysis. Predictions are developed using skills of best visual fit to data trends rather than depending on models or mathematical equations. 

The presentation is divided into two main sections. 

The first deals with observations of temperature, ice area, ice volume and rate of change, and is supported by analysis of the underlying causal feedback mechanisms. 

The second part explores some of the consequences and implications of Arctic Dynamics, for the region itself and for the wider world, both physical and social. 

The language, though scrutinised for scientific accuracy, is free of technical jargon and kept as close as possible to the clarity of spoken English.

Professor Peter Wadhams Discusses Subsea Permafrost Methane Releases And Impacts on Civilisation

In this interview conducted in November 2013, Professor Peter Wadhams of University of Cambridge, UK, explains how methane releases such as those being witnessed in the Arctic could impact life on Earth.
