Three years to safeguard our climate

Source: Adapted from UNEP Emissions Gap Report 2016 Climate Action Tracker and Climate Central - click for full size image

Christiana Figueres and colleagues set out a six-point plan for turning the tide of the world’s carbon dioxide by 2020.

In the past three years, global emissions of carbon dioxide from the burning of fossil fuels have levelled after rising for decades. This is a sign that policies and investments in climate mitigation are starting to pay off. The United States, China and other nations are replacing coal with natural gas and boosting renewable energy sources. There is almost unanimous international agreement that the risks of abandoning the planet to climate change are too great to ignore.

The Uninhabitable World

Famine, economic collapse, a sun that cooks us: What climate change could wreak — sooner than you think.

It is, I promise, worse than you think. If your anxiety about global warming is dominated by fears of sea-level rise, you are barely scratching the surface of what terrors are possible, even within the lifetime of a teenager today. And yet the swelling seas — and the cities they will drown — have so dominated the picture of global warming, and so overwhelmed our capacity for climate panic, that they have occluded our perception of other threats, many much closer at hand. Rising oceans are bad, in fact very bad; but fleeing the coastline will not be enough.

Indeed, absent a significant adjustment to how billions of humans conduct their lives, parts of the Earth will likely become close to uninhabitable, and other parts horrifically inhospitable, as soon as the end of this century.

2015-01-14 Saving Electricity in Appliances and Lighting

Energy usage monitor
This presentation is based on my study of saving electricity in my own home, and was given to a meeting of the South Essex Area of the I.Mech.E., the I.E.T., and the Chelmsford Science and Engineering Society.

2012-05-25 Condensing Boiler with Annual Efficiency of 96%

For a seminar held in London, I prepared – but did not give – this presentation. It drew on my work on 'Measuring the Heat Losses and Solar Gains of Buildings' and explained briefly how such a high annual efficiency had been achieved.

2004-07-30 Energy Solutions for 60% Carbon Reduction – Part II

This study was prompted by the Royal Commission on Environmental Pollution Report No. 22, "Energy - the Changing Climate", and by the U.K. Government Cabinet Office Performance and Innovation Unit (PIU) Energy Review. It adopts the target of a 60 % reduction in UK carbon emissions by 2050.

2010-05-03 Pathways to Renewable Transport Fuels

I and Dr Richard Pearson were invited to a meeting held by Air Fuel Synthesis. In connection with this, I produced a roundup of renewable fuel plants in Europe, finding seven, and synthetic renewable fuel activities in the USA, finding two.

2014-01-16 NHK Fukushima 'Meltdown' Documentaries

There have been many official enquiries into the Fukushima disaster (2011-03-11). However NHK, the leading Japanese broadcaster, waited a year or more until people were ready to talk, interviewed over 300, later 400, of those directly involved and outside experts, and collected huge amounts of data. This has enabled realistic re-enactments of the sequence of events. So among many other programmes on the Fukushima disaster, NHK has produced three 'Meltdown' documentaries in English, first broadcast on 2012-01, 2012-08-18, and 2013-03-05. This last was about 24 months after the disaster

Avoiding Climate Change Disaster

A short paper on the actions we must take soon in order to meet a carbon budget target which will limit global warming to 2 degrees and to arrive at a viable sustainable energy scenario thereafter.

2017-07-10 Climate and Energy Topics

Topic 1) emphasises the urgency of energy transition.

Topic 2) is the main focus of the document, with the paper by Sgouridis et al, 2016.
This identifies the relationship between the remaining fossil fuel emissions cap, the transition time, and the required investment in Renewable Energy (RE) supply plant.

Topics 3) and 4) refer to the initial conditions prior to the energy transition.

Topic 5) compares the Energy Return on Investments (EROIs) of Renewable Energy (solar and wind power) supply measures with the weighted average value of 20 assumed by Sgouridis et al.
Topic 6 is concerned with the global limits of renewable power sources.
Where Topics 3) and 4) deal in UK quantities, Topic 6) deals in Global quantities. However, the UK must expect to use only a proportionate share - e.g. equal per capita.

Topics 7) and 8) consider energy demand measures as complements of the supply measures assumed by Sgouridis et al. They refer to two papers by Cullen and Allwood et al, 2010 and 2010.
Including energy demand measures will greatly ease an energy transition within the constraints, such as 2 C global warming.
