New interactives!

We’re happy to announce some new interactive learning tools that will be a part of Dargan’s upcoming interactive book Climate, Justice and Energy Solutions. Check out a new version of the Future Climate, where you set emissions by gas or sector to see how temperatures increase.

An energy simulator, where you can replace all fossil fuel emissions with the clean electricity needed to power it all.

And a solar power simulator at the neighborhood scale, to see what kind of electricity demand can be satisfied with solar and storage alone.

Enjoy and keep an eye out for more interactive apps, including some that gather all of these modules together!

EarthGames on Cool Solutions radio show!

The most recent episode of the Cool Solutions radio show/podcast featured EarthGames director Dargan Frierson, Pandemic creator Matt Leacock, and Solutions designer Sam Levac-Levey talking about climate games! Listen below, and check out Deal, Climate Conversations, and support EarthGames here!

Chart out Earth’s future with a real climate model!

Here at EarthGames, we’ve been making a lot of interactive climate science tools with the Godot game engine recently. The first one is ready to share! It’s a simple climate model, with just a few equations underneath, tuned to emulate state of the art climate models.

It starts from today, and allows you to change total emissions relative to today with a single slider. Put in your preferred deep decarbonation pathway, and see whether global temperatures exceed thresholds like 2 C or 1.5 C.

New version of Deal! More ways to play EarthGames!

Support for bold climate action is strongest it’s ever been! The road to the Green New Deal is still going to be difficult but we’re making a lot of progress.

That’s why we’ve made our notoriously difficult game Deal: A Green New Election a little bit easier! We’ve also added description of the real-world campaign that this game is inspired by, and improved the user interfaces of the game. Check out Deal version 2.0 on iOS or Android!

We’ve also made a few more EarthGames available to play in your browser on The new uploads are

The first three should give you a similar experience to the previously available mobile versions. Deal is not optimized for browsers, so we recommend you play it on a phone or tablet using the app store links above if possible. We hope that these free browser-based versions of the games will help make them accessible to even more players!

You’re invited… to Destination Wedding 2070!

Our new project, an interactive improvised storytelling role-playing game called Destination Wedding 2070 kicks off tomorrow!  Join us as we marry family disasters with the climate crisis!  You can play along by blogging as a character, or just follow along with what everyone’s writing on reddit.  Check out the main site for all the details!  This netprov runs from Nov 3-11, 2019.

Destination Wedding 2070 is an attempt to make data about climate change more comprehensible. Although climatologists have strong models of the decades to come, they typically report it via graphs and charts.  DW70 goes beyond visualization by bringing the data to life in data dramatization as participants experience the effects in a speculative future scenario.


The data for this data dramatization netprov has been brought to you by EarthGames and was based on simulations from the CanESM5 model under SSP585, a high emissions scenario that represents substantial increases in fossil fuel use in the coming decades.  Climate model data is usually presented in terms of averages, but each simulation creates weather across the globe. The forecasts from each city are adapted from particular Saturdays in 2070. The maps show the model data across the globe for max/min temperature, precipitation and humidity, and city forecasts are taken from the nearest gridbox or from a heuristic downscaling approach.

dehli daytime highWe made forecasts for 5 sublime wedding locations: Issaquah, Washington (near Seattle); Neemrana Fort Palace, India (near Dehli); Mar del Plata, Argentina; The Bund, Shanghai, China and Key Biscayne, (Miami) Florida, USA.  Each site faces a unique climate catastrophe as a backdrop.  

The creators of Destination Wedding 2070 are Samara Hayley Steele, Mark Marino, Rob Wittig, and Dargan Frierson.  Joining us are a team of storytellers, which you can be a part of!  The improvisational narrative of the weddings will head in all kinds of unexpected directions as netprov participants read and respond to each others diary entries using the improv principle of “yes, and…”!



New article on EarthGames lead designer Andrew McDonald!

Andrew’s on the front page of!!  Read about the great work he did on mosquito/NET this summer in this article by Douglas Esser.

Have you tried out his new version of mosquito/NET yet?  Read about the project here, and download for free for iOS and Android.  The new app is not just about mosquitoes.  It allows you to track sightings of animals, insects, and birds as well, as well as experiencing some fun new gamification methods.

Deal: A Green New Election

It’s almost Election Day, and your ballot initiative is clinging to a narrow lead in the polls. Voters are concerned about effects on jobs and cost of living, and the press is waiting for answers about difficult policy questions. An angry fossil fuel CEO has contacted you with a proposal that sounds an awful lot like a threat. And do I smell smoke??

In honor of this historic day of climate action, we’re proud to release our newest game, Deal: A Green New Election!  It’s available for free for iPhone/iPad and Android (Google Play).  You can play it on your phone on the way to the climate strike!  Although mobile is the preferred platform, we’ve also created a version that you can play in your browser.

We here at EarthGames are so inspired by the movement building around the Green New Deal.  In this game, you’re part of a team trying to pass a ballot initiative which will be voted on directly by the the voters in your state.

The Green New Deal would mobilize the workforce to build clean energy and resilient infrastructure, while addressing environmental justice and income inequality along the way.  But do you have the passion and skill to get your initiative passed?

Over the 15 week campaign (which can be played through in just 5-10 minutes), you’ll

  • Make decisions about what voters to target and messaging
  • Meet cool characters based on real-world climate activists
  • Respond to difficult interview questions
  • Witness fossil fuel infrastructure disasters
  • Encounter angry CEOs
  • Learn about environmental justice
  • Probably face some pretty harsh opposition
  • And much more…

When making this game, we were inspired by real-life heroes of the Green New Deal, and hope you’re inspired to join their organizations, like the Sunrise Movement, Zero Hour, and  A list of some of our Green New Deal heroes is on this page  — we hope you’ll listen to their speeches and read their words about the Green New Deal!


The team who made Deal: A Green New Election includes:

Dargan Frierson
Jasmine Leung
Arman Kazi
Sisir Kadiveti

Thanks to all the play testers and climate activists we worked with as well!

The Green New Deal and Climate Politics: Flourish Dev Blog #3

The recent launch of the Green New Deal resolution marks a turning point in the politics of climate change in America.  The plan is stunning in its ambition, putting us on a course towards a low-emissions, climate-resilient future with a massive 10 year mobilization of the nation’s resources.  It also recognizes that such rapid changes would come with large societal costs, if safeguards aren’t put in place.  You might think such an ambitious policy would lack public support, but it’s quite the opposite: polls have shown approval ratings above 80%.

The issue of climate change is more in the public eye in America than ever before.  So with this update, we’ll change direction from describing the climate engine to talk a little about Flourish’s political engine: the equations and data behind public opinion in the game.  The engine is fully predictive: it evolves in time, changing in reaction to player choices, random events, and climate.  It also determines the actions that you’re able to take in your country.  If your constituency doesn’t believe in global warming, they won’t allow you to make bold strides to solving the problem.  We think the engine can help predict reactions to the Green New Deal and other climate policies as well.

The engine is heavily based on a series of studies by the Yale Program on Climate Change Communication called “Global Warming’s 6 Americas.”  These studies suggest that Americans can be usefully separated into 6 different groups in terms of their beliefs about climate action.  We summarize characteristics of the 6 groups below.

  • Alarmed: who both accept the scientific consensus about human-caused global warming, and are already taking action to address the problem.
  • Concerned: who accept the scientific consensus but have not yet started taking action themselves.

Note that alarmed and concerned now make up 59% of the country.  Concern about global warming has risen substantially in recent years.   These two categories made up only 43% of the public in 2013.


  • Cautious: who lean towards accepting the science but don’t think it’s an urgent problem to address.
  • Disengaged: who haven’t thought much about climate change, perhaps because they have bigger problems, because they don’t know about it, or because they don’t think about politics.
  • Doubtful: who often believe that recent climate changes are natural and we’re already doing enough to solve the problem.
  • Dismissive: who believe that climate change is a hoax, and actively try to convince others of their views.

Which of the 6 categories are you?  Although I might wager that if you’re reading this you’re “alarmed,” you can take a 4 question quiz to find out.  Here’s my result:


Who wants to be known as Alarmed though??  We’re trying to rebrand this group as “Woke”!

When the first 6 Americas study was released in 2009, I was most struck by how small the dismissive group is.  Their intense interest in promulgating their views means they’re seen disproportionally in public debate, in comment sections of news articles, etc.  But this group simply does not make up much of the public.  Further, research has suggested that the dismissive group are unlikely to ever change their minds.  So dismissives tend not to be worth your time to debate (unless others are listening)!

In Flourish, in every region, whether player- or AI-controlled, we keep track of the fraction of the population that falls into each of the 6 groups.  The initial partitioning into these categories is based on polling data, from the Yale group or extrapolated from international surveys about climate change awareness and threat perception.

In order to calculate the public approval of a given climate action, we keep track of approval rates of each group individually, then add up the totals given the fraction of the population in each group.

Should you be considered that our political engine for the world is based on a set of studies about the US??  We sure are!  We think about conscious biases like these, and the many unconscious biases that must be present in the game on a daily basis.  Our (perhaps meager) justification for 6 Americas as the basis of a worldwide system is that we don’t take the categories too literally in their interpretation.  For instance, while “disengaged” in the US might be associated with those who are not politically engaged, in many countries it would represent people who have immediate concerns that are significantly greater than climate change, e.g., war, hunger, poverty.  Also, it’s just a starting point.  Further complexity can always be built in to correct biases.

Can the Flourish political engine help us understand policies like the Green New Deal and their likelihood of success?  The current high approval rating is doubtlessly due to the fact that it has aspects that appeal to groups who aren’t very concerned with climate, like job guarantees.  Tying climate to economic stimulus makes Green New Deal-style legislation much more likely to have lasting success as compared to initiatives that simply put a price on carbon.

In order for any climate policy to be enacted, however, it has to go through a virtual wringer of opposition from special interests who want it to fail.  These groups are extremely well-funded and powerful, and have been remarkably successful (undefeated?) in the past.  The 2018 Green New Deal-like ballot initiative in Washington state ended up attracting over $31 million in out-of-state oil money to oppose the initiative (over $10 per vote cast!).  Given the huge support rate, the onslaught of opposition attacks from outlets such as Fox News over the last few weeks are not surprising.  Those agents are doing their best to chip away at the 80% who now want a Green New Deal, and are likely succeeding to some extent.

To represent how public opinion responds to attacks like these in a game, we need to think about how public opinion can change.  We use a mathematical technique called Markov chains to describe how the 6 groups evolve in response to events like disinformation campaigns.  This system will be described in the next blog entry.

If you’re feeling “alarmed” and want to support our efforts to build Flourish, you can donate to the EarthGames Support Fund.  Donations right now would go to supporting Andrew McDonald to be a paid undergraduate research assistant on the project.  You can read about Andrew’s prior experiences developing augmented reality games with EarthGames here and here.

Flourish dev blog #2: Global methane emissions

In the last post we wrote about carbon dioxide, the #1 cause of global warming.  But methane, the #2 contributor, is not exactly negligible.  It’s caused 20% of global warming so far.  Each molecule is much more important than CO2: around 30 times as much if considered on a 100 year timescale.

Methane concentrations (as measured in ice cores and direct measurement) have also skyrocketed since preindustrial times:


Compare methane with carbon dioxide, which has risen by 45% since preindustrial times.  Methane reached a 45% larger level than its preindustrial concentration back in the 1920s!  There’s now over 2.5 times the methane in the air than in preindustrial times.  Methane has much smaller concentration than CO2 — 2 ppm vs 400 ppm.

There was some indication recently that concentrations were leveling off, but CH4 is back on the rise since 2006:


Natural gas is mostly methane, and so is swamp gas, which is produced in wetlands by tiny microorganisms called methanogens.  Methanogens work well in warm, wet, low-oxygen environments, so wetlands or flooded rice patties are big sources.  So are the bellies of cows, sheep, and goats — and even termites!  Methane is a big reason why beef has such a high carbon footprint.

There’s a lot of methane locked up in permafrost and ice in the Arctic, and there’s also huge amounts of frozen organic material that’s ripe for decomposition by methanogens.  Certain Arctic lakes have methane bubbling to the top, where they can be lit on fire!  There’s concern about these sources releasing or creating more methane as the climate warms, leading to an amplifying feedback that causes even more warming.  Scientists are closely monitoring methane emissions in the Arctic, and worldwide, to identify potential surprises.

However, it’s quite difficult to estimate with precision how much methane comes from different sources.  Estimates from the individual sources on the ground don’t add up to the atmospheric increase/sinks.  Different groups provide their own estimates of the sources, three of which are shown below (GAINS-ECLIPSE5a and EDGARv4.2EXT from the Global Methane Project spreadsheet and CEDS).


Why would methane concentrations have stabilized starting in 2000, and accelerated in 2006, if there were no matching trends in the anthropogenic emissions?  Scientists are still arguing about that one, but it could be that natural wetland sources have changed, that concentration of the hydroxyl radical (the main way methane breaks down) in the atmosphere has changed, or that we haven’t accounted all the sources well enough.

About those anthropogenic sources.  Leaking coal mines, natural gas wells, and pipelines contribute a tremendous amount to methane emissions, and have risen sharply since the early 2000s (data from CEDS):


For example, the Aliso Canyon natural gas storage facility in Los Angeles began spewing tons of methane (watch infrared video footage here) and other chemicals in October 2015.  Local residents began suffering from headaches, nose bleeds, and other illnesses, and eventually thousands of families were forced to evacuate.  The leak wasn’t capped until February 2016, by which time over 100,000 tons of methane had leaked.

There is little government oversight on these wells, and industry self-regulation is not exactly stellar.  Check out this article for descriptions of some of the utter failures of risk management in the industry.  SoCalGas recently agreed to a $119M settlement, which will go to offsetting methane emissions across the state, a long-term health study of affected residents, and environmental justice-related projects, among other projects.

Imagine 1500 Aliso Canyon blowouts each year.  That’s the best estimate of fugitive methane leakage from coal, oil, and natural gas facilities across the world.  Could we be doing a better job at detecting leaks?  The Environmental Defense Fund plans to launch their own satellite called MethaneSAT for much-needed oversight on fugitive fossil fuel emissions.

The waste category includes methane released from landfills and water treatment.  Note this source has more than doubled since 1970.  There are ways to mitigate these, e.g., capturing biogas from landfills or installing methane digesters to water treatment facilities.  And we shouldn’t forget (gasp!) creating less waste.

Rice is typically grown in flooded fields, which create anoxic conditions that methanogens love.  There are well-known methods to reduce these emissions and grow more efficiently at the same time.

Finally, animal agriculture is another major source of methane, specifically ruminants that have multiple stomachs for digestion.  Cows, goats, and sheep all burp out large amounts of methane in their digestive system.  There simply wouldn’t be nearly as many cattle on the planet if it wasn’t for our appetite for beef.  When combined with the inherent inefficiency of animals as a calorie source (it takes 30 pounds of feed to create 1 pound of beef, per the USDA), the meat industry has an extremely high carbon footprint.

Are we shifting towards less meat intensive diets?  Definitely not — as the world becomes more rich, more and more people are demanding more meat in their diet.  Projections suggest that satisfying the demand for more meat is the main challenge for feeding the world in future decades, not rising populations.

The future doesn’t have to be like these projections though.  That’s why we’re making Flourish.  If you want to support our efforts to build this game, you can donate to the EarthGames Support Fund.  Donations right now would go hiring a paid student research assistant.
