If you’re not yet scared…

In our brainstorm session yesterday, someone (Faraz?) suggested I could kick off the ICSE session with a short video. The closest thing I can think of is this:

Wake Up, Freak Out – then Get a Grip

It’s not too long, it covers the recent science very well, and it is exactly the message I want to give – climate change is serious, urgent, demands massive systemic change, but is not something we should despair over. It also comes with a full transcript with detailed references into the primary scientific literature, which is well worth a browse.

Except that it scares the heck out of me every time I watch it. Could I really show this to an ICSE audience?

Distracted by the footprints

At many discussions about the climate crisis that I’ve had with professional colleagues, the conversation inevitably turns to how we (as individuals) can make a difference by reducing our personal carbon emissions. So sure, our personal choices matter. And we shouldn’t stop thinking about them. And there is plenty of advice out there on how to green your home, and how to make good shopping decisions, and so on. Actually, there is way too much advice out there on how to live a greener life. It’s overwhelming. And plenty of it is contradictory. Which leads to two unfortunate messages: (1) we’re supposed to fix global warming through our individual personal choices and (2) this is incredibly hard because there is so much information to process to do it right.

The climate crisis is huge, and systemic. It cannot be solved through voluntary personal lifestyle choices; it needs systemic changes throughout society as a whole. As Bill McKibben says:

“the number one thing is to organize politically; number two, do some political organizing; number three, get together with your neighbors and organize; and then if you have energy left over from all of that, change the light bulb.”

Now, part of getting politically organized is getting educated. Another part is connecting with people. We computer scientists are generally not very good at political action, but we are remarkably good at inventing tools that allow people to get connected. And we’re good at inventing tools for managing, searching and visualizing information, which helps with the ‘getting educated’ part and the ‘persuading others’ part.

So, I don’t want to have more conversations about reducing our personal carbon footprints. I want to have conversations about how we can apply our expertise as computer scientists and software engineers in new and creative ways. Instead of thinking about your footprint, think about your delta (okay, I might need a better name for it): what expertise and skills do you have that most others don’t, and how can they be applied to good effect to help?

Software Engineering for the Planet (version 2.0)

Here’s an updated description of the ICSE session I kicked off this blog with. Looks like we’re scheduled for the second morning afternoon of the conference (Thurs May 21, 11am 2pm), straight after the keynote.

Update: Slides and notes from the session now available.

Software Engineering for the Planet

This session is a call to action. What can we, as software engineers, do to help tackle the challenge of climate change (besides reducing our personal carbon footprints)? The session will review recent results from climate science, showing how big the challenge is. We will then identify ways in which software engineering tools and techniques can help. The goal is to build a research agenda and a community of software engineering researchers willing to pursue it.

The ICSE organisers have worked hard this year to make the conference “greener” – to reduce our impact on the environment. This is partly in response to the growing worldwide awareness that we need to take more care of the natural environment. But it is also driven by a deeper and more urgent concern.

During this century, we will have to face up to a crisis that will make the current economic turmoil look like a walk in the park. Climate change is accelerating, confirming the more pessimistic of scenarios identified by climate scientists [1-4]. Its effects will touch everything, including the flooding of low-lying lands and coastal cities, the disruption of fresh water supplies for much of the world, the loss of agricultural lands, more frequent and severe extreme weather events, mass extinctions, and the destruction of entire ecosystems [5].

And there are no easy solutions. We need concerted systematic change in how we live, to reduce emissions so as to stabilize the concentration of greenhouse gases that drive climate change. Not to give up the conveniences of modern life, but to re-engineer them so that we no longer depend on fossil fuels to power our lives. The challenge is massive and urgent – a planetary emergency. The type of emergency that requires all hands on deck. Scientists, engineers, policymakers, professionals, no matter what their discipline, need to ask how their skills and experience can contribute.

We, as software engineering researchers and software practitioners have many important roles to play. Our information systems help provide the data we need to support intelligent decision making, from individuals trying to reduce their energy consumption, to policymakers trying to design effective governmental policies. Our control systems allow us to make smarter use of the available power, and provide the  adaptability and reliability to power our technological infrastructure in the face of a more diverse set of renewable energy sources.

The ICSE community in particular has many other contributions to make. We have developed practices and tools to analyze, build and evolve some of the most complex socio-technical systems ever created, and to coordinate the efforts of large teams of engineers. We have developed abstractions that help us to understand complex systems, to describe their structure and behaviour, and to understand the effects of change on those systems. These tools and practices are likely to be useful in our struggle to address the climate crisis, often in strange and surprising ways. For example, can we apply the principles of information hiding and modularity to our attempts to develop coordinated solutions to climate change? What is the appropriate architectural pattern for an integrated set of climate policies? How can we model the problem requirements so that the stakeholders can understand them? How do we debug the models on which policy decision are based?

This conference session is intended to kick start a discussion about the contributions that software engineering research can make to tackling the climate crisis. Our aim is to build a community of concerned professionals, and find new ways to apply our skills and experience to the problem. We will attempt to map out a set of ideas for action, and identify potential roadblocks. We will start to build a broad research agenda, to capture the potential contributions of software engineering research, and discuss strategies for researchers to refocus their research towards this agenda. The session will begin with a short summary of the latest lessons from climate science, and a concrete set of examples of existing software engineering research efforts applied to climate change. We will include an open discussion session, to map out an agenda for action. We invite everyone to come to the session, and take up this challenge.

Software Engineering for the Planet

I’ve been pondering starting a blog for way too long. Time for action. To explain what I think I’ll be blogging about, I put together the following blurb, for a conference session at the International Conference on Software Engineering. I’ll probably end up revising it for the conference, but it will do for a kickoff to the blog:

This year, the ICSE organisers have worked hard to make the conference “greener” – to reduce our impact on the environment. Partly this is in response to the growing worldwide awareness that we need to take more care of the natural environment. But partly it is driven by a deeper and more urgent concern. During this century, we will have to face up to a crisis that will make the current economic turmoil look like a walk in the park. Climate change is accelerating, outpacing the most pessimistic predictions of climate scientists. Its effects will touch everything, including the flooding of low-lying lands and coastal cities, the disruption of fresh water supplies for most of the world, the loss of agricultural lands, more frequent and severe extreme weather events, mass extinctions, and the destruction of entire ecosystems. And there are no easy solutions. We need concerted systematic change in how we live, to stabilize the concentration of greenhouse gases that drive climate change. Not to give up the conveniences of modern life, but to re-engineer them so that we no longer depend on fossil fuels to power our lives. The challenge is massive and urgent – a planetary emergency. The type of emergency that requires all hands on deck. Scientists, engineers, policymakers, professionals, no matter what their discipline, need to ask how their skills and experience can contribute.

We, as software engineering researchers and software practitioners have many important roles to play. Software is part of the problem, as every new killer application drives up our demand for more energy. But it is also a major part of the solution. Our information systems help provide the data we need to support intelligent decision making, from individuals trying to reduce their energy consumption, to policymakers trying to design effective governmental policies. Our control systems allow us to make smarter use of the available power, and provide the  adaptability and reliability to power our technological infrastructure in the face of a more diverse set of renewable energy sources. Less obviously, the software engineering community has many other contributions to make. We have developed practices and tools to analyze, build and evolve some of the most complex socio-technical systems ever created, and to coordinate the efforts of large teams of engineers. We have developed abstractions that help us to understand complex systems, to describe their structure and behaviour, and to understand the effects of change on those systems. These tools and practices are likely to be useful in our struggle to address the climate crisis, often in strange and surprising ways. For example, can we apply the principles of information hiding and modularity to our attempts to develop coordinated solutions to climate change? What is the appropriate architectural pattern for an integrated set of climate policies? How can we model the problem requirements so that the stakeholders can understand them? How do we debug strategies for emissions reduction when they don’t work out as intended?

This conference session is intended to kick start a discussion about the contributions that software engineering can make to tackling the climate crisis. Our aim is to build a community of concerned professionals, and find new ways to apply our skills and experience to the problem. We will attempt to map out a set of ideas for action, and identify potential roadblocks. We will start to build a broad research agenda, to capture the potential contributions of software engineering research. The session will begin with a short summary of the latest lessons from climate science, and a concrete set of examples of existing software engineering research efforts applied to climate change. We will include an open discussion, and structured brainstorming sessions to map out an agenda for action. We invite everyone to come to the session, and take up this challenge.

Okay, so how does that sound as a call to arms?
