Again, taking the corona crisis as an example, what we are doing now is trying different available antiviral drugs, convalescent plasma therapy and undertaking vaccine trials. In our hypothetical scenario with forest and climate change, the Klimawald (“Climate forest”) concept is like a combination of two methods: antiviral drugs and convalescent plasma therapy. Wherein the former is about using a certain combination of existing drugs to treat the disease, and, the latter involves transfusion of plasma from a COVID-19 recovered patient into an infected patient. Thereby, the antibodies present in the plasma of the recovered patient helps to neutralize the SARS-CoV-2 virus in the infected patient. Similarly, in our climate forest, a species is selected to be planted for its ability to tolerate drought or the ability to enhance the resilience of the forest in future climatic conditions. We planted 11 species of conifers and broad-leaved trees; 7 of them are native; 4 come either from Southern Europe, the Mediterranean mountains or from North America.

Now, let us move on to the real world, where things are more complex and challenging. Just like it is not easy to convince people to adopt social distancing, it is not easy to bring people from diverse backgrounds and different interests for a common cause. “Why did we build Klimawald?”, “What was the need?” and “How far we have succeeded?” were some questions we asked ourselves. We acknowledge the responsibility of maintaining the beauty of this planet in a way that it was given to us. Centuries ago, Ludwig van Beethoven said, “How happy I am to be able to walk among the shrubs, the trees, the woods, the grass, and the rocks! For the woods, the trees and the rocks give man the resonance he needs.” We hope our future generations will be able to describe the beauty of forests as he did.

The project Klimawald began under the title “Carbon Offset Week” in which we – the initiators –  wanted to organize a planting campaign for people who wish to offset their carbon emissions. When the Office of Land, Forest, and Agriculture (AELF) and Hospitalstift willingly offered a hectare of land for plantation, the concept of “Carbon Offset Week” was revised. Now, the aim was not only to plant trees, but also to restore a damaged forest, and, therefore, with Dr. Gregor Aas and Dr. Birgit Thies we developed the concept of Klimawald (“Klima” meaning climate and “wald” meaning forest in German). We identified four major threats to German forests: low species diversity, long and intensive droughts, the velocity of climate change and the dispersal rate of trees. Klimawald model suggests thinning, planting diverse species, and selecting future-oriented species. We built Klimawald to acknowledge our carbon footprints, take responsibility for the impact of human-induced climate change and contribute to prepare forests for future scenarios.

Ecologist Eugene P Odum once said, “The future belongs, not to those who have the most, but to those who do the most with what they have”. In our case, we had one hectare of forest land which was converted from spruce-pine forest to mixed forest with the help of scientists, forestry practitioners, students, and citizens. Apart from the human resources, the financial resources for the project were covered through donations and support from our partners. The success of a project depends on how an action is followed up by another. In the case of Klimawald, the planting event in spring was followed by two watering events in summer. The average survival rate was about 90% at the end of August 2019.

What we learned from this project is that the knowledge can be translated into action when individual interests synergize. Klimawald also showed us a way to hold dialogue with different sections of our civil society. Some of our partners and supporters who had never worked together found common grounds to cooperate. The idea of Klimawald not only generated interest among the citizens of Bayreuth, but it has moved beyond its borders and motivated students from Höxter to develop their own Klimawald Höxter. It also led to the development of a similar project by our team members in South Korea. In the meantime, the Klimawald site has become a spot for excursion and environmental education. The project also stirred a debate on the model of climate forests. In the forthcoming year, we want to improve the project, build close networks and take further actions.

Overall, the experience of developing an idea of Carbon Offset Week into a Klimawald project was very enriching. According to a Korean proverb, “고생 끝에 낙이 온다 (gosaeng kkeute nagi onda)”, delights come at the end of hardship (English translation), and a delightful moment has arrived in the journey of Klimawald. Out of 160 projects in Germany, Klimawald is now nominated for the award “Blauer Kompass 2020” of the German Federal Environment Agency. Apart from three jury awards, there is an audience award for which the voting has already begun, and we are in the second spot as of April 15, 2020. Global Change Ecology (GCE) is an international study program and so is our team. The diversity of nationalities is a strength of GCE students. And to confront a global problem like COVID-19 or climate change, we need this strength!

We hope that the help and support received during the planting and the watering event will be showered on us again for the “Blauer Kompass 2020” competition. Klimawald was built with your participation and will stand the test of time with your participation. Because the story has just begun…

Could you imagine a world in which we just consume less energy, instead of having better technology?

Well, in my lectures I had some discussion of the limits to growth movement and the idea that we should learn to live within the ecological limits or constraints. I was very critical about it, pointing out, that the thesis is often formulated in terms of resources and the idea that we are depleting sort of non-renewable resources and we should learn to live within our means. But even people who are in this literature, recognize that the issue is actually not about resources, it is all about energy. Because almost any resource that we consume could be recovered and turned back into that resource with enough energy. And that is certainly the case in climate change. We can take atmospheric carbon dioxide and turn it back into fossil fuel – with enough energy. So, it’s all about energy. Then you have to look at how much energy we are consuming and also what the energy budget of the planet is. The most striking statistic in this area is that the total human energy consumption right now on the planet is about 18 Terawatts. The energy budget that is available to us in the form of just solar radiation is over 89 000 Terawatts. Therefore, there is absolutely no scarcity of energy on this planet. The problem is that humans are not very good at harvesting that energy. Most of our energy systems are parasitic upon plants. Plants through photosynthesis are able to capture solar energy and turn it into a high energy chemical bond. And we rely upon that for our food systems directly, but then with fossil fuels we are relying upon that indirectly. That’s all energy that is captured by plants. We capture a bit of it with wind power, and differential heating with solar energy, with water power, like rain and so on, this all comes from solar energy. And of course the direct solar energy. But the amount that we are capturing directly is less than half a Terawatt maybe. We humans apparently haven’t tried very hard. Because plants capture it and that has always been sufficient. We had horses and cattle that ate the grass and then we used the horses and the cattle as our machines to plough our fields and so on. And then fossil fuel got discovered and it’s like: Oh, plants aren’t just doing this now. Plants have been doing this for millions of years and it’s all stored up onto the ground. So, we just discovered this incredible convenient way of harvesting past deposits of solar energy. So, what we have to learn is how to capture ambient solar energy and transform it into a useful form. But the amount of solar energy that’s available is mind-bogglingly large. There is a kind of purity about that we should just learn to live within our means or learn to live with less energy. That’s actually like saying: You should learn to use less water. And in Canada, there is water everywhere. This planet is not lacking water. And anyway, there is no reason to learn to use less water if you can do desalination and stuff like that. So, water is plentiful. There is no reason why we should have to limit our consumption of water. But similarly, energy is even more plentiful than water. And there is just is not any principled reason why we should have to use less of it rather than more.

Except for the point that we are not able to harvest the solar energy efficiently right now.

A lot of the debates of the limits to growth and lot of the discussion about environmentalisms – what they really come down to, is optimism versus pessimism about human ingenuity. About whether or not people are kind of clever enough to figure how to do these things, whether or not the rapid technological progress that we have seen in the last two hundred years can continue. And I am an optimist.Let’s use China as an example: you have a country with a billion people, many of them very, very smart. If you look at the innovations about technology – it’s almost all come from the Western countries, from Europe and North America, and the amount of technological innovation that has come from other parts of the world is extremely small. Largely just because of development. As other countries are developing – which they are – then more humans are available, more people will have scientific and technological training to think about these questions.  If China started being technological innovative that would just transform the human condition. So, I just don’t see the case for pessimism.

Do you think there are also implications for every single one of us?

Yes – and I like to emphasize that because sometimes I talk to students and activists, who sometimes want to treat climate change as though it is one of these bad guy stories of corporations wrecking the world. Students at my university are trying to push for a boycott of oil companies, as though climate change is caused by evil corporations. And I like to point out to them that there is a fact of the matter as to whether or not large social problems are caused by corporate misbehaviour or not. For example the 2008 financial crisis was caused by corporations, there was nothing in the world or in the average person’s behaviour that contributed to their crisis. It was the fault of the banks, in part because of the bankers having inappropriate incentives. That is something you can actually blame corporations for. But climate change is something that every single one of us contributes to, with few exceptions. But every single one of us, living in a first world country contributes to it, because every aspect of our life relies upon energy that relies on fossil fuel. Therefore every single person can do something about it because every single person is complicit in the problem. Other than in the financial crisis where I actually couldn’t do anything about it. With climate change we are all guilty and that’s actually why everyone of us should do something about it.

Do we have a moral obligation to take the wealth of future generations into account, when thinking about climate action?

That’s a very complicated philosophical question, that many people have treated as though it were an easy question. The easy answer is yes. But, if you do that in a too simplistic way, it can actually lead to really absurd implications on the policy front. The reason why there’s a philosophical topic here is that it is not obvious, like we should fix this problem. The reason it’s a philosophical problem, is that question turns out really complicated. What I did over the course of the five lectures was actually to address that kind of problem, in order to show how difficult it is. My answer would be very nuanced and complicated and therefore is probably not worth trying to summarize in one sentence.*

* Here you can watch the livestream of the lectures to learn more about moral obligations to future generations.

Last Question: Can you explain briefly why there should be a discount rate?

(Editor’s note: The discount rate means basically that you would rather have 100 € now that in two months. The decrease in value for you when having 100€ only in two month is called discount rate. Regarding to climate change, having a discount rate means assuming that people in the future will be wealthier (because of economical growth) and can therefore deal better with climate change issues than we can now.)

That’s actually the thing that people from the sciences have the greatest difficulty understanding. It’s very typical for people with technological education. The same issue comes up with the construction of roads for example. Engineers want to build everything out of concrete because that’s the best way to build. It’s the most durable, it’s the most long lasting and so on. So, they submit all the plan of how they want to build the road and then it goes into the accounting office of the local municipality where some accountant then applies a discount rate. And when it comes back, the road gets build out of asphalt. And it drives engineers crazy because they prefer concrete. The problem is that concrete has this higher upfront cost with lower maintenance, whereas asphalt is cheaper to build now but has higher maintenance costs. So, it looks like it’s just a false economy. The discounting thing is actually the most common source of disagreement between people who look at things from a more scientific/technical way and people who look at it from a more economic and social science perspective. There should be a discount rate and there are a variety of reasons. The simplest reason for why there should be a discount rate is simply the fact that people will be richer in the future than people in the present. And as a result, cost is simply not as significant in the future as it is now. The municipality is having to repair a road in ten years. If there is economic growth that means the municipality is going to have more tax revenue in ten years than it has now. And so a million-dollar liability is less of a concern if it can be delayed for ten years. That’s just sort of rational accounting. It gets more complicated than that, but that’s the core rationale for a lot of discounting. And that’s the least controversial aspect of discounting. That is actually a major point of contention. When it comes to climate change, a lot of the people of earth sciences focus on the consequences and don’t see that, in order to translate that in a policy you have to add in a number of other factors that make it more complicated. Economic growth being one factor and what the impacts of economic growth are to the human capacity to adapt to climate change is a major factor. So, you have to be able to have a model that predicts that. And you have to figure out what impact it is going to have on discounting. There is a lot of frustration and I understand the frustration a lot of people in the natural sciences feel discussing how we should respond to climate change. But it is important not to be too propria about the science. Science contributes one piece of the puzzle. But there are a bunch of other very important pieces s well.

Thank you very much, Prof. Heath!

The post “I just don’t see the case for pessimism.” – Interview with Prof. Heath Part 2 appeared first on Global Change Ecology.

Thank you very much for these inspiring lectures. Could you tell us, why you started to address the issue of climate change?

So, I’m from Canada and in Canada this is actually an extraordinarily decisive issue, because Canada has enormous proven oil reserves and fossil fuel production is a major part of the economy. But we also have enormous potential for renewable energy. And so, portions of the country get all the electricity from hydroelectric power and therefore have a minimal carbon footprint. Other parts of the country have just absolutely outrageous carbon emissions by pumping out literally the dirtiest, most polluting oil in the world. (Editor’s note: In Canada tar sands are very common.) There is a very intense political conflict that has a regional dimension in Canada about what we should do about climate change. And of course, being next to the United States, there is a huge temptation to wanting to do nothing about it. I do think we have an obligation to do something about it. But, there isn’t anything like a policy consensus. Anything you say is going to be strongly contested. In part, because there is such a conflict of interest within the country concerning this issue. So, you really have to have good arguments for your policy because there are going to be people disagreeing with anything anybody says on the question. That was how I got interested in this topic. In many ways, it is the most pressing political issue in the country.

What are – in your opinion – the major changes society will face due to climate change?

Well, that’s a good question. It depends on how we respond to it. If we do nothing, and climate change occurs, then I think, the major impact is going to be climate refugees. It’s probably where the most significant damage it’s going to be caused. It is actually one of the damages that is harder to quantify. But if you have a large-scale collapse of agriculture in a state like India or if you would have extreme weather dispossessing millions of people… Just look at the chaos that ten million Syrians refugees have caused and think now about what 200 millions or 400 millions refugees looks like. (Editor’s note: However, Syrian refugees are not climate refugees.) That can easily overwhelm our political systems.  And also, none of our current refugee systems recognizes climate refugees because they get classified as economic refugees. And so, there is a huge conceptional difficulty in how to handle that. I guess that’s the big issue.

But I think that, if we respond appropriately to climate change the biggest impact is going to be technological development in our energy systems. Because one of the things about energy is that the 20th century was a period of almost total stagnation in the development of technology – in energy systems. Almost all of our energy systems are actually 19th century technology. So, if you look at electricity, batteries, steam engines, internal combustion engines – I mean somebody from the 19th century let loose today would be able to recognize the basic technology that we are using. Whereas in terms of information technology someone from the 19th century would not recognize anything, right? There have been all kinds of areas in which there’s been huge technological innovation. And energy has been completely stagnant. And I think the major reason for that is that fossil fuel was so cheap and it provided so much energy that there was no reason to research alternative energy strategies, because it was as close to free as it could get. So, I think climate change gives us a good reason to get more serious about technological innovation in energy systems. And if we respond appropriately we will also create incentives for people to do that. So, I am actually a technological optimist about energy systems. And you could imagine a world in which the constraints of scarcity on energy would be very significantly lifted through technological innovation. So that would be the happy outcome of how we respond to climate change.

What should policy do to deal with the issue of climate change?

The overriding imperative is that you need to price carbon. That’s the crucial thing. And there are agreements about how people see that working. Coming from a country where there is this massive internal conflict over fossil fuel, the idea that you are going to tell people for example in Alberta (the state where the oil sands in Canada are): “Oh, this stuff has just going to stay in the ground, you just can’t dig it up” is actually politically impossible given the wealth associated with it. I have difficulty in picturing any global governance system whereby we all just agree to rules about emissions and everybody obeys that and this permanently resolves the problem. I can’t imagine that happening.

What’s really important is that the appropriate incentives are created for technological innovation. What resolves it in the short term are policies like carbon taxes and emissions trading. But the long-term solution has to be technological. Otherwise people are going to dig up the oil because it is basically energy, highly concentrated energy, just sitting there. And so, the temptation to use it is overwhelming. I think the policy response should be pricing, that is the crucial thing, because pricing targets exactly the problem of carbon emissions. But the rationale for that is to make it in a way that the unfair competitive advantages fossil fuels have enjoyed over other energy systems get eliminated. Right now the problem is that it doesn’t pay to research or to invest in solar energy, wind energy and so on, because people burning coal don’t have to pay for the carbon emissions. It’s an unfair advantage that they have.  We have to get rid of that unfair advantage to motivate people appropriately.
