BigPicture.TV Lecture Series

This BigPicture.TV set of video recordings covers the key aspects of Climate Dynamics. It was originally recorded in February 2007. The illustrated text can also be accessed as html presentation and pdf.
July 07Presentation 1: Climate Feedback This video presentation explains how the future of our climate will be affected by feedback mechanisms that may amplify global warming. Of the 20 feedback mechanisms that have been identified, this describes the most significant - the Albedo Effect (or the way in which ice reflects solar radiation back into the atmosphere); water (for instance how water vapour amplifies the greenhouse effect); and why the acidification of the world's oceans can hamper the absorption of carbon dioxide.
July 07Presentation 2: Climate Uncovered

Part 1

Part 2
This two part-series examines the components of our climate system. The carbon cycle, relating to the amount of carbon in the atmosphere, is of fundamental importance, but there are other critical factors driving climate change, including the roles that the oceans and vegetation play.
July 07Presentation 3: Feedback Dynamics

Part 1

Part 2
There are around 20 feedback mechanisms that could potentially accelerate climate change. This two-part series examines three main categories of feedback. The best known of these is the the carbon cycle feedback, driving an atmospheric increase in CO2. Hybrid feedbacks constitute a second category and are driven by a combination of increased CO2 levels and higher temperatures. The third feedback category is purely temperature-driven.
July 07Presentation 4: Tipping Points and Critical Thresholds The climate cycle fluctuates between alternating ice and warm ages. However, unprecedented levels of greenhouse gas concentrations now threaten to distort historic patterns. Amplifying feedbacks may trigger a tipping point that accelerates global warming, threatening an era of climate chaos. Beyond such a point our efforts to stem the tide of climate change may prove ineffectual.
June 07 Climate Stabilisation Positive feedbacks are now accelerating global warming and threatening to send it out of control. Stabilisation of the Climate in this complex system with long time delays now requires a strategic intervention that turns off the heat before it is too late (i.e. reduces "radiative forcing" to zero). This paper highlights the scale of the task ahead.
June 07 Address to the Club of Rome, October 2005 This paper, delivered in October 2005, outlines the current context of climate change and introduces the work on Feedback Dynamics. The imperative of mobilising effective action changes the role of science from pure information provision to applied change agency. Recognition of the "State of Global Emergency" leads into an outline agenda of the scientific response. This section, the origins of the "Apollo-Gaia Project", also raises the critical question concerning an appropriate institutional locus. The address concludes with a brief reflection on the psycho-dynamics of social change.
Mar 07The Climate Escalator

(YouTube mini-presentation)
A vivid parabolic illustration of feedback dynamics and the acceleration of climate change.
Mar 07Critique of IPCC Report & Introduction to Apollo-Gaia

(YouTube mini-presentation)
Introduces evidence of the 'dumbing down' of the text of the Summary for Policy Makers of the current IPCC Report, followed by an outline of the need for a global response (the Apollo-Gaia Project).
Mar 07 Political Corruption of the IPCC Report? Analysis of changes in the Final Text of the "Summary for Policy Makers" of the Fourth Assessment Report, WG1: The Physical Science Basis, throws light on the direction in which political and economic interests have influenced the presented scientific material.
Mar 07 Feedback Dynamics and the Acceleration of Climate Change A condensed update of current scientific analysis.
Feb 07Climate Sensitivity: A Whole-Earth Dynamic Approach This brief working paper moves away from the world of computer modelling to examine the Vostok ice-core data for information that could throw new light on the issue of climate sensitivity. If the sensitivity figures indicated in this study of the Vostok data can be trusted, we face an urgent and radical re-evaluation of the current strategic response to global warming.
Dec 06Response to Dr. Malte Meinshausen whose work is currently being used as a foundation for the European response to climate change. The task faced by the global community is now the avoidance of catastrophic climate change, let alone dangerous climate change. Meinshausen severs the relationship between the goal of relating to the fundamental realities of the global climate and what he describes as "policy-goals" - determined by political, economic and other vested interests - without recourse to the fundamental science. Even within the terms of reference of the attempt to achieve "policy-goals" Meinshausen's approach is fatally flawed. The realistic problems we face in the mitigation of dangerous and catastrophic climate change are far too important to allow this kind of work to be used as a basis for policy formulation and strategic action, whether at national, European, G8 or global levels.
Dec 06Update to David Wasdell bio-note  
Nov 06 Apollo-Gaia Project Outline of the Apollo-Gaia Project. Its target is the stabilisation of the climate of "Gaia", the whole-earth system. Presented at the Washington Summit on Climate Stabilisation and subsequently as part of the Aurelio Peccei lecture to the European Chapter of the Club of Rome in Brussels.
Nov 06Climate Change navigation page New navigation page giving access to Beyond the Tipping Point, The Feedback Crisis in Climate Change, Global Warning, Feedback Dynamics Model, and the Apollo-Gaia Project pages
Oct 06Beyond the Tipping Point: Towards the Anthropocene Extinction Event Positive Feedback and the Acceleration of Climate Change: further revision in preparation for the Washington Summit on Climate Stabilisation.
July 06Beyond the Tipping Point: Towards the Anthropocene Extinction Event Positive Feedback and the Acceleration of Climate Change presentation made to The Foundation for the Future, Humanity 3000 Workshop, Seattle, April 2006, updated and revised and presented to the Campaign Against Climate Change, June 2006, and the UBS Seminar on land usage, July 2006.
Apr. 06Feedback Dynamics Project Details of the Project convened in order to establish a global analysis and modelling capacity, to test the conceptual climate feedback model, to quantify the complex feedback system and to determine the time-frame of its behaviour. Replaced by the Apollo-Gaia Project - see above.
Mar. 06Feedback Model Addition of html version of the underlying conceptual model behind 'The Feedback Crisis in Climate Change', accessible from various pages within the 'Feedback Crisis' paper.
Jan. 06Of Clarity and Climate Change This review of James Lovelock's new book "The Revenge of Gaia" highlights the fundamental scientific analysis of the dynamics of climate change that lies at the heart of the book. Lovelock's weakness in the field of social science is identified as the source of his inappropriate despair and the book is hailed as a clarion call to effective collective action.
Jan. 06Feedback Model Addition of PowerPoint Presentation of the underlying conceptual model behind 'The Feedback Crisis in Climate Change', accessible from various pages within the 'Feedback Crisis' paper.
