 Hello, how are you? I'm here to talk about the open climate network. My name is Evan Pedromo. I'm probably best known in this community as being the founder of WikiTravel, the WikiTravel Guide that is now a Wikimedia project, Wiki Voyage. I'm also known for my work creating open source social networks like Idenica, working on open standards for social networks. I'm a former Wikimedia where I was product manager for APIs, but today I'm here in my current role as director of open technology at the Open Earth Foundation. The Open Earth Foundation is a U.S. non-profit. We have a worldwide team from Europe, Africa, South America, North America, and our goal is making open source software for a thriving planet. We work with universities to bring research projects into open source products, and we also partner with international organizations like UNFCCC, the UN organization tasked with fighting climate change. Speaking of which, we are in a climate emergency on this planet. I'm really sorry if this is the first you've heard of it. We are at a point where we have had a temperature rise of 1.1 degrees Celsius over pre-industrial average temperatures of that 0.7 C has been increased since 1990, so within the lifetime of most of the people in this room. This is causing catastrophes around the world as we all see in our newspapers, online, etc., from my home country of Canada, where our boreal forest is currently causing evacuations to the far north in Yellowknife to Maui and Hawaii, Tropical Storm Hillary, which is going to be the first tropical storm to hit California in 80 years, as well as heat waves, sea level rise, war, drought, refugee crises around the world. Climate change is a real and present danger for all of us. The cause of climate change, global warming, is caused by our injection of CO2 and other greenhouse gases into the atmosphere. Scientists best guess on how much carrying capacity our atmosphere has is about 450 parts per million of CO2. We are dangerously close to that limit with approximately 411 parts per million currently, so we are and we continue to inject CO2 and other greenhouse gases into the atmosphere at a rate of about 50 megatons per year, excuse me, 50 gigatons per year. But all is not lost. In 2015, the leaders of the world came together and agreed to voluntary cuts in their emissions of CO2 and other greenhouse gases with a long-term goal of keeping the increase of global average temperature to well below 2.2 degrees above pre-industrial levels, hopefully down to 1.5. The way that they are doing it is by having agreed upon voluntary cuts in their emissions and submitting climate plans. Every single signatory needs to do this, and many are aiming towards net zero climate emissions by 2050, and some are aiming for cutting their emissions in half by 2030. Of course, when you have this kind of voluntary framework for any kind of system, transparency is key, and that is why the UNFCCC is managing a system called the global stock take. This is where all the countries in the world who have been working on climate change for the last eight years do a voluntary self-evaluation, see how well they have actually done, lowering their emissions, and that is brought together by UNFCCC. This is the first year 2023 where this global stock take is taking place, and it will happen this December as part of the COP28. So, very exciting. We have a problem, but the nations of the world are coming together to solve it, and they're gathering data to figure out how well they've done. Well, that is the upside. This is the downside, is that national governments are not the only players, the only actors when it comes to climate change. Countries are, of course, important, but states, provinces, regions also have climate policies, cities, corporations, even individual emission sites like mines or farms or factories. All of them have levers of control to decide how much carbon dioxide goes into the atmosphere. So, these actors don't work in a vacuum, they have relationships, for example, part-whole relationships. The city of Austin is part of the state of Texas, which is in turn part of the United States, and they have a relationship in the way that they actually execute on their climate goals. Similarly, there's ownership, a core mining in Chicago owes a mine in Palma Rejo, Mexico, and that mine has impact on the world climate change. We need to be able to understand what the relationships are between those actors at those different levels. Actors obviously need this information in order to harmonize their climate targets in order to understand how they're doing and also to organize and share climate actions and climate plans. They need to be able to understand what each other are doing in order to make good plans. But we all need this information also for corporations or business entities. We need to know who to do business with, who it makes sense to reward with our business, who to encourage in their work, and also who to hold accountable. So, climate data at all of these levels is extremely important. Data distribution right now, the distribution of this data right now, is very widely spread across the web. Many of these entities have 50 or 100 page PDF reports on their own websites. Some data is compiled by regulators. For example, the EPA in the United States tracks a lot of data and does make that available, as well as the previously mentioned UNFCCC, but in some places that information is hard to get and obviously it's spread around the world with different regulators. In academic journals, this information is also tracked, but it's spread across multiple journals around the world. And of course, as with any data sets, any two data sets are going to have two different schemas, unless they're well agreed ahead of time. We have different data formats in document or machine readable data, as well as different methodologies for understanding what kind of climate data needs to be done. In order to deal with this wide array of actors and the climate data that they are providing, the OEF, my organization in partnership with UNFCCC and our various academic partners, has developed a system that we call a digitally enabled independent global stocktake or DIGS, where we track emissions, targets, and actions for actors around the world. We bring in data from international and national regulators, academic and self-reported data, and we harmonize it into a single schema that we provide through our API. This API is restful and open, well documented, all our software is of course open source. We have libraries for data scientists to use to incorporate our data into their own models, as well as for other kinds of interfaces. We also federate our data into a well-known system called the OS climate data commons that makes our data available across the internet, so this data, big database is available for calculations. We have an explorer of our data that covers some of the some of the interface, but does cover some really interesting aspects. It's at openclimate.network, you can see the link on the on the page, and we have a github where we maintain not only all of our code, but also our source and harmonized data sets, and it's all available under a very liberal APL license. What we've learned during this time, well first of all we've incorporated over 63 data sources from countries around the world, from these different international sources. We've got data, we're tracking data currently for 147,000 actors at all those different levels, and we currently have about 360,000 annual CO2 emissions records, as well as 4,000 targets, that's stated targets of these different actors. You can see some interesting things that we generate out of our data sets, so on the left you see emissions of the top seven actors, which cover a majority of the CO2 in the world. On the right you see per capita emissions. We also can do work again, working directly at our API, seeing how well different actors are on target for their goals, so this is showing the UK's targets, and it's not quite on track. We can also use the part whole relationships for things like tracking if a actor is on, is well harmonized with its parts, for example this is showing that the emissions targets for the country of Canada are much lower than for the different parts of Canada, the provinces and territories. We're working on making our contributions easier, we currently use GitHub flow, we'd like to be using more systems for doing that. Probably the important thing for us is that we have learned through this process that not enough actors at the regional and city level are providing emissions data, reporting it or tracking it, and one of the things that we are doing right now is working to help cities do their own carbon accounting, so we can take that 1% of cities, or excuse me, 5% of cities that are reporting emissions targets and bringing it up to a higher level, more along the lines of regions or countries. If you have questions or you'd like to try our system, it's at openclimate.network, I'm evanatopenearth.org, you can follow me on the fediverse at evanatsocialopenearth.org. Thank you very much, oh I should check questions. Great, so the first question, how can affiliate like Wikimedia's for sustainable development collaborate with you? Two important things that we need to do, first of all, is help us develop our techniques for bringing in data and collaborating data, and then secondly is that we'd really like to figure out the best way to take the data that we've collected already and make it available through Wikidata to the other projects within the Wikimedia family. Thank you very much, that's my time.
