An Open Letter to World Leaders

There is an open letter from young climate activists to world leaders stating their demands of governments. It was written by Greta Thunberg, Luisa Neubauer, Anuna de Wever van der Heyden and Adelaide Charlier. They sum up the global situation with admirable clarity and to me their demands are sensible. They are seeking more signatures to this letter.

Please read the letter and sign it. The more of us do so the more the media and world leaders will pay attention. Thank-you.

The Disunited State of America

It is with a huge sense of relief that the Trump presidency is over. It is too early to say how things will work out under President Biden, but his actions over these past few days seem very positive. He has signed up to the Paris climate agreement, cancelled the Keystone XL pipeline, and rejoined the World Health Organisation and a host of other good initiatives.

Commentators are discussing the deep divisions in American politics. Many are saying that these go back to the 1960’s the Vietnam War and the liberalizing of social values. I think that the roots of division go very much further back.

Ever since its inception the USA has been a country of bizarre contradictions. It was founded upon colonialism, slavery and the genocide of Native Americans and it remains a country of extreme inequalities. Yet it often portrays itself as a beacon of peace, justice and democracy. These contradictions run deep.

USA has long trumpeted democracy while covertly backing coups and installing far right regimes abroad, often with the backing of UK and other governments. Jason Hickel lists some of them: Iran in 1953, Guatemala 1954, Congo 1961, Brazil and British Guiana in 1964, Ghana 1966, Indonesia 1967 and Chile 1973, to name but a few.

What is much less well known is the history of the American’s Nazis during the 1930’s and of a plot led by several wealthy businessmen to overthrow the democratically elected government of Franklin D Roosevelt in 1933.

Far right extremists have long played a major role in American politics. In 1898 in Wilmington, North Carolina, white supremacists burned the offices of the first black owned newspaper, murdered black people and forced the State government to resign, and because they essentially got away with it, this allowed the subsequent growth of the Klu Klux Klan. Much of the Christian church in USA is deeply racist, and reminds me of the Dutch Reformed Church in Apartheid era South Africa.

In a very interesting article the political economist Blair Fix analysis American history through the lens of class struggle. Over the last forty years inequality has rapidly grown more extreme, with mass impoverishment accompanied by extreme and excessive increases in wealth for a tiny minority. It is high time for the neo-liberal era to come to an end.

The inauguration of Joe Biden and Kamala Harris was a day to celebrate. The young poet Amanda Gorman’s stirring poem ‘The Hill We Climb’ captured this joyous moment in the tangled history of America. Let us hope that America can move forward in the spirit of reconciliation and hope that Gorman calls for. The extent of the climate and ecological emergency, mass impoverishment and deep social divisions are all major challenges requiring a bold new direction, and early indications of the new administration are looking very promising. However the forces of the far right will oppose their actions every step of the way, in ways that may be democratic or deadly.

My person of the year is… many millions

Maria Kalesnikava, one of the many brave women leaders in Belarus, currently in prison

This year my person of the year accolade goes not to one person, or to a few, but to the many millions of people around the world active in trying to make it a better place. To all the people who are striving for justice: social justice, economic justice, climate justice, ecological justice, every kind of justice. Thank-you!

Many of the big powerful countries have been dominated by ghastly politicians over the last few years; the very best in terms of national governments have tended to be small countries, very much less covered by the media. If Trump, Putin, Bolsonaro, Duterte, Modi and our very own Boris Johnson represent all that is bad, who represents all that is good? Finland’s Sanna Marin, Iceland’s Katrin Jakobsdottir and New Zealand’s Jacinda Ardern I think are the three outstanding Prime Ministers currently in office. However each of these is governing a small country with a long history of democratic governance. Obviously it is much harder to take over a country which has had a long history of corruption and poverty. Maia Sandu is the new Prime Minister of Moldova and she seems to be trying to set the country onto a better path.

Yesterday there was a global wave of relief as the inauguration of President Biden and Vice President Kamala Harris put an end to the Trump presidency. It is not to Biden or Harris that I want to pay tribute today, but to the millions of activists who have worked for this change over the last four years.

Recent days have seen extraordinary scenes in Russia. Alexei Navalny, the opposition leader poisoned with polonium by Putin, returned from Berlin to Russia and was immediately arrested. Along with the young Russian climate activist Arshak Makichyan, these are two very brave and inspirational Russians.

In neighbouring Belarus we are now into the 165th day of continuous street protest. These protests have represented something powerful: well organized, brave, creative and peaceful protest actively supported by the majority of the population, and led by some truly remarkable women. Hopefully sooner, rather than later, Lukashenko will fall.

Worldwide there are millions of great climate activists and today I’d just like to acknowledge the tireless campaigning of three young women from Africa, Patricia Kombo from Kenya, Kaossara Sani from Togo and Oladosu Adenike from the Lake Chad Region.

Thank-you one and all.

My technology of the year

One of GivePower’s new solar desalination projects

On this blog at about this time of year I usually choose my ‘technology of the year’, and a person of the year. Today I’ll cover my technology of the year and in a few days I’ll write a blog about my person of the year.

My technology of the year is the solar photovoltaic panel. Of course, these panels have been around for decades. This year the very long term falling price has passed a critical threshold, and now solar is the cheapest form of electricity in most parts of the world. Costs are predicted to keep falling for years to come. The implications for every part of the global economy are profound. Oil, coal, gas and nuclear industries will become increasingly uncompetitive, their assets will become stranded, and bankruptcies are inevitable.

Photovoltaics will have many new uses. I’ve blogged before about numerous ground breaking solar technologies, from the first solar powered ship and plane to circumnavigate the Earth to the first car with integrated solar cells. Today I want to highlight three uses of solar that I think will be significant.

The first is the new Aptera solar powered car launched a few weeks ago in San Diego, California. It is very light weight, super aerodynamic, covered in photovoltaics, and, it is claimed, can travel one thousand miles without the need to stop and re-charge. It is very much more energy efficient than just about any car I can think of, with the possible exception of the Riversimple Rasa. If both cars and humans are to have any future, this is the way they all must go.

Solar powered desalination is as yet a tiny industry, but I think it will grow massively in the near future. An organization called GivePower has recently installed a few systems, including a couple in Kenya at Kiunga and Likoni, each capable of providing water for up to 35,000 people all day every day, using solar panels, batteries and a reverse osmosis desalination unit. There is a vast global need for this kind of technology to provide the approximately one billion people who do not currently have access to clean water with it.

How we integrate solar power into our agricultural landscape is going to be an important issue. The goal is to grow more and better food, and to produce clean energy, off the same land. This is our best hope for creating space for rewilding, tackling climate change and feeding humanity. BayWa and Groen Leven are developing clear photovoltaic panels under which crops can be grown. They are working with Wageningen Research centre and five Dutch fruit farms to test different levels of translucency on various types of fruit. Early results are looking promising. This system may well replace polytunnels as the maintenance costs look lower, the agricultural productivity higher and the ecological impact less damaging. These photovoltaic panels may replace ordinary glass in greenhouses, just as global greenhouse use expands rapidly.

Brexit and the Bigger Picture

The UK has left the EU. The Brexiteers have had their way. The media coverage of the EU and the forces that pushed for us to leave it has been woeful for decades.

George Monbiot, I think quite correctly, sums up the drive for Brexit as being one aspect of a war within capitalism. What he refers to as housetrained or domesticated capitalism has just lost one major battle in its struggle against the forces of warlord capitalism. Watch this excellent 6 minute video or read this blog from George.

Mark E Thomas in his book ‘99% Mass Impoverishment and How We Can End It’ examines this struggle within capitalism. His chapter four, on what he refers to as ‘market fundamentalism’ is more or less what Monbiot refers to as Warlord capitalism, and it is an ideology that has chilling ramifications. Market fundamentalism sees democracy and the needs of the vast majority of humanity as a burden. It prioritizes wealth accumulation of the richest few over absolutely everything else.

To my mind market fundamentalism, or warlord capitalism to use Monbiot’s term, is a terrifying philosophy, the logical outcome of which is total impoverishment for billions of people. Now our challenge is to overcome this evil through concerted action.

In a blog written just after the Brexit vote in 2016 I contrasted the strongly pro EU stance of Scotland under Nicola Sturgeon’s leadership with the chaos that Brexit was about to unleash on the UK, and how these divergent paths would probably lead to the break-up of the UK. The paths Scotland and the UK are on continue to be ever more divergent.

Boris Johnson is the puppet clown front man, behind which the forces of market fundamentalism are destroying the institutions of the UK. Meanwhile Scotland has linked up with Iceland, New Zealand, Wales and Finland to form the Wellbeing Economy Governments partnership (WEGo). It is the very antithesis of everything the market fundamentalists believe in. The two forces are in conflict. Which one wins may well determine humanity’s future. The market fundamentalists care not a jot about the climate and ecological emergency, WEGo is our best hope to tackle these issues and to do so in a caring and compassionate manner. (I shall write more about WEGo over the coming months)

Molly Scott Cato, one of our finest MEP’s, together with the German MEP Terry Reintke, posted a blog looking forward to a better future and a time when the UK rejoins the EU. I for one remain both European and British, locally Herefordian and globally engaged. Brexit is not over now, nor will it ever be. I look forward to us rejoining the EU.

There is a global struggle of epic proportions. On the one side the market fundamentalists and on the other an emerging network of activists and governments promoting planetary and human wellbeing. In a way the break-up of the UK or our membership of the EU are minor skirmishes in this epic struggle.

Carbon Emissions: have they Peaked?

In an article published today in Grist Shannon Osaka considers if global carbon emissions peaked in 2019.  2020 saw emissions fall by 7%, or 2.4 billion metric tons. Clearly 2020 has been a weird year, and the fall may be due mainly to the Covid19 pandemic. As the above graph shows emissions have sometimes dipped in certain years, due to various crises, only to rebound the following year. It is of course too early to say for sure if emissions have peaked and if and how quickly they will then descend.

In December 2015 I wrote a blog wondering, and hoping, that carbon emissions had peaked in that year. Instead they rose again from 2016 to 2019. In that blog I posted two graphs, the first highlighting the small decrease in emissions in 2015, the second from the UN assuming a peak in emissions in 2030 and what the UN called an impossibly steep cut in emissions thereafter.

The fall in emissions in 2020 has been dramatic. Most opinion is that post Covid there may be some rebound toward higher emissions, or that emissions may jog along not going up or down a great deal. There is of course another possibility that emissions will plummet every year from now on until we reach net zero, and then into net negative, where the Earth is sequestering more carbon than is being emitted.

If we look at the graph below it shows how various energy technology costs have changed over the last decade. Solar photovoltaic panels have been coming down in price for many years. Between 1976 and 2019 the price of solar modules has fallen by 99.6%., and as the graph shows the fall in the last decade has been 89%.

Wind, both onshore and offshore, concentrating solar thermal and many forms of energy storage such as batteries and green hydrogen have all also fallen in price by considerable amounts. Fossil fuels and nuclear are slowly pricing themselves out of the market. Worldwide more coal power stations are closing than are being built, and this trend will only accelerate.

Of course to get to net zero as soon as possible will require more than just market forces. We need to change almost every aspect of our global turbo charged capitalist throw-away society. More and more people understand this and are busy creating the new economy. Millions of activists are raising their voices in calls for change. Most of our politicians are utterly inadequate for the task at hand, but even they may move in the right direction. Some better politicians are emerging in many countries, and over the coming months I’ll highlight a few of the best.

For now I just want to stress that the Covid pandemic, combined with falling costs of renewable energy, give us a window of opportunity to reconsider our collective future as a species. Let us cooperate to rapidly bring down emissions, and build a better future. We live in a multifaceted emergency, out of which something better may just be beginning to emerge.

The Wye, Reimagined!

Extinction Rebellion activists hold a vigil for the River Wye, Saturday 19th Dec 2020

The River Wye, like so many of Britain’s rivers is in a sorry state. It is suffering from decades of damage caused by poor farming practices. Phosphate pollution is a major issue stemming from intensive poultry units, excessive use of artificial fertilizers and old and poorly functioning sewage works and septic tanks. Excessive ploughing is leading to soil erosion after heavy rain. Maize, unsustainably grown for bio-digesters, is especially vulnerable to soil erosion. These are just some of the problems affecting the Wye catchment area. Herefordshire Wildlife Trust’s Andrew Nixon gives his list of what is wrong here. Helen Stace, the Trust’s director, writes about a recent act of ecosystem vandalism by a local farmer on the River Lugg. Investigative journalist Nicola Cutcher writes about pollution on the Llynfi, a Welsh tributary of the Wye. Yesterday Extinction Rebellion held a vigil on the old bridge in Hereford to draw public attention to the crisis affecting our rivers. George Monbiot, Franny Armstrong and Nicola Cutcher are crowdfunding for what I am sure will be a fascinating live documentary to be called Rivercide.

All this is about what is wrong, with just a little about some of the small things that could be done to mitigate the damage. I want us to now re-imagine the whole Wye catchment differently. We could utterly transform the whole ecosystem, producing more food while also massively benefiting wildlife. Here’s how.

Protecting and rebuilding soil is of critical importance, and the scope for solving multiple problems is immense. Gabe Brown, a farmer from North Dakota, has been a pioneer in regenerative agriculture. He has five principles of soil health: ‘no-till or minimal tillage, keeping the ground covered, diversity in plant and animal species, keeping living roots in the soil as much as possible, and the importance of integrating animals.’ By applying these principles he has managed to increase his soil organic matter from 1.9% in 1991 to 6.1%, so increasing the rate at which water can percolate down into the soil from half an inch per hour in 1991 to eight inches per hour now. This increase in permeability massively reduces risks of both flooding and drought. The raised level of organic matter also increases fertility while sequestering carbon. Imagine if all farmland in the Wye catchment adopted these methods.

We could go further, as agroforestry pioneer Martin Wolfe demonstrated at Wakelyns farm over the last 25 years. Now several others are developing the most amazing farms utilizing agroforestry alley cropping. Outstanding among them is George Young of Fobbing in Essex. He is planting rows of the most extraordinary variety of fruit and nut trees, with a great diversity of nutrient rich grains and legumes grown in the alleys and is now integrating red pole cattle into the system. He, like most regenerative farmers, is gradually reducing all his chemical inputs and slowly converting to organic systems.

If we return to reimaging the Wye catchment where the entire area was converting to systems of organic agroforestry, with a very much greater diversity of trees and bushes, arable crops and livestock all integrated into each acre. As we did so we could close down all intensive poultry units and replace or repair all malfunctioning sewage works and septic tanks. We would then have massively reduced the risks of flooding and of drought, of pollution and of soil erosion. We could of course go further still. Many areas would benefit from rewilding. Some farms might want to follow the extraordinary example of rewilding set by Isabella Tree and Charlie Burrell at Knepp farm in Sussex. The reintroduction beavers would have a very positive effect, acting to slow the river, reduce erosion and create a wonderful network of habitats for more species to colonize. The Wye could once again have the biodiversity and health it had hundreds of years ago, and it could simultaneously produce more and better food than it ever has.

Carbon Emissions & the Scale of Change

Carbon Emissions need to fall to below zero. Historically prosperity has led to high emissions. That needs to change.

Atmospheric carbon dioxide levels are today at 413.66 parts per million (ppm). A healthy biosphere would ideally be at around 285 ppm, which is roughly what it has fluctuated around for the past 10,000 years, or the entire duration of human civilization. Climate scientists often talk of 350 ppm as a safe upper limit. The Paris Climate Agreement was signed five years ago in an attempt to reduce emissions, but it has failed. Emissions need to drop to zero and then we need to sequester massive amounts of carbon dioxide back out of the atmosphere. Most governments talk of reducing emissions, and in some sectors of the economy they may succeed, but no country is yet at zero emissions, let alone the required net negative emissions.

If we look at the graph above it shows the extent of our challenge. Historically increases in wealth have only come about with rising emissions. The countries with the smallest carbon footprints are all very poor whereas all the richest countries have higher carbon footprints.

It seems to me entirely possible to have prosperity for all 7.8 billion of us human beings, and to do so in a way which is carbon negative. To achieve that everything needs to change. This is not just about how we generate and use energy, or about how we farm or about ending our throwaway culture. Yes, all those things need to change, but so too does the distribution of power and money.

A recent report by Oxfam stated that the carbon emissions of the richest 1% are more than double the emissions of the poorest half of humanity. Richer countries, and especially richer individuals, have a huge moral responsibility to reduce emissions.

Many millions of people are active campaigners for climate action and climate justice. We have been on demonstrations, lobbied MP’s and tried to live more sustainable lifestyles. Some people have even set up innovative companies to try and change the technological basis of our society. The global school strikes movement deserve particular praise for keeping the issue in the media spotlight.

For my part I am currently writing a book about the scale of change required, and once every month or two I give a talk on Zoom, the next one being on 6th January. These things have kept me rather pre-occupied during the last few months and so these blogs have been rather less frequent than they used to be: apologies for that. If you want to be added onto the talks and discussions list, which includes my talks, and lots of other interesting things from The Left Bank programme, you can fill out this MailChimp form.

Energy Futures: Belgium

Graph from Federal Planning Bureau in Belgium: but is it correct in its prediction of rising fossil gas use to replace nuclear power?

Belgium has just formed a new government. It is a coalition of seven parties, including both the Belgian Green Parties Ecolo and Groen. One long term policy of most European Green Parties is to phase out nuclear power. The chart above has been produced by the Belgian Federal Planning Bureau and predicts a big rise in the use of fossil gas. This quite naturally is drawing considerable criticism as just when Belgium, like all countries, should be rapidly decarbonising, it threatens to increase emissions.

However I think the graph is wrong. It predicts solar increasing from 5% to 6% between 2015 and 2050, and wind from 8% to 32% over the same period. This to me seems a massive underestimate of both. Solar and wind have been getting steadily cheaper, more efficient and with higher capacity factors for many years, and this trend is predicted to continue. The chart, and much of the debate on Twitter and elsewhere assumes the choice is between nuclear and gas, both of which are already costly, each have environmental downsides and future costs look high.

Belgium is already ramping up its offshore wind farms and has plans for more. Better insulated buildings, more efficient appliances, more walking, cycling, home-working and public transport should all act to decrease overall energy demand. So too will the transition from a throwaway linear economy to a circular economy. Gradually pretty well all new buildings everywhere will have solar panels installed.

Two trends that do not appear on this chart are of significance. The first is distributed local energy storage. Many houses will have batteries, in electric cars and larger static ones. Green hydrogen will also be produced at scale. All these will facilitate the greater take up of wind and solar, so together they will make up more than the 38% predicted in the graph. They may make up 70%, possibly 90%, of Belgian electricity demand by 2050.

The second trend is long distance renewable energy trading. Belgium, like Germany, will probably be a net energy importer, being densely populated, quite highly industrialized and with relatively poor wind and solar resources. Denmark is already planning to export wind power to Holland, Germany and Poland to help them decarbonize. Scotland, Norway and Iceland all look well positioned to be net energy exporters, with their huge wind, hydro and geothermal resources and relatively low energy demand. However the biggest renewable energy exporters are likely to be from the sunniest countries.

North Africa is one huge area where solar will be developed at scale. Morocco’s Ouarzazate solar park is one of the most exciting energy infrastructure projects anywhere on Earth. Many more large solar parks will be built, utilizing both concentrating solar thermal and solar photo-voltaic systems, and will also have on site energy storage with batteries for very short duration of a few minutes to a few hours, solar thermal heat stores for up to 24 hours, and on-site electrolysis for hydrogen production and so energy storage over weeks, months or even years. Energy will be exported via high voltage direct-current cable and as hydrogen using tankers or pipelines.

Germany is investigating purchasing green hydrogen from Australia, and Australian entrepreneur Mike Cannon-Brookes is planning to connect a cable from Australia to Singapore to supply 20% of Singapore’s electricity. The long distance trade in renewable energy is a relatively new phenomenon, and consequently often overlooked by energy planners. It will be a huge global industry very quickly: the economics look good, and it will be vital for global decarbonisation.

So back to Belgium and their new coalition: my advice to them is hold fire on any new investments in fossil gas, even if that means a slower ramping down of existing older gas and nuclear power stations. Invest in demand reduction through changes to buildings, transport, work patterns, circular economy etc. Invest in renewables, energy storage, and interconnection and longer distance sourcing of green hydrogen.

Apologies

I think it is about nine weeks since I posted a blog, so apologies to regular readers. That is I think the longest gap I’ve had in over ten years of blogging. I have been rather engrossed in thinking about a book I’ve wanted to write, and have had several attempts at. Just starting again: daunting and exciting.

I’ll be posting a blog in a few hours…
