Among the world's ever-expanding array of board games, a small but growing number deal with climate change. But are these games any good?
As a professor of English who specializes in environmental literature, I set out to learn how well these board games portray the perils that global warming poses to the planet. Are they an effective way for students to learn some of the science and stark realities behind the persistent heating of Earth?
I invited half a dozen climate activists and educators to try the games out to answer these questions and more. My thought was that if people learn best while they are active and joyful participants, then turning a serious topic like climate change into a board game might have value beyond the game.
No individual winners
Most board games - think of Monopoly or Catan - are zero-sum competitions: One player wins a clear victory over the others. But since climate change affects the whole world, climate change board games emphasize teamwork and group success. Either all players win together, or no one survives. These board games have a narrative arc that can spark discussion about values, perspective, conflict, emotions and decision-making.
And those are precisely the kinds of discussions my colleagues and I had while sharing pizza and salad over the course of the evening. Together, we evaluated the games for their ease to learn, their value for teaching about climate catastrophe, their ability to spark conversation and their suitability for high school and university students.
What follows is an account of the five climate change board games that we all tried.
1. Solutions
Solutions draws upon scientific solutions researched by Project Drawdown, which is a nonprofit that pushes for solutions to climate change. The game, played in rounds, requires players to draw two cards that each carefully describe a way to reduce global emissions.
Players discuss the two options and rank which one is better for the climate. Correct decisions reduce global temperatures, while incorrect guesses damage the planet. Players also roll the dice to determine further actions that could potentially make global temperatures rise.
We all agreed the game could be a valuable learning tool since it was easy to learn and based on accurate scientific information. The need to evaluate different solutions easily sparked conversation, and the information was suitable for upper-level high school students and university students.
2. Kyoto
Another game that we ranked highly is Kyoto, which has players simulate a high-stakes climate negotiation summit. We each represented a country, and the cards we drew determined our secret national interests. To win the game, we had to bargain with each other, pay fees, bribe and try to persuade each other to reach climate goals.
Initially, I doubted the educational value of the game because, due to the draw of the cards, players who represented the U.S. could only win the game if they increased global carbon emissions, as determined by the coal-industry-friendly cards. Who wants a game where players try to raise global temperatures?
But through discussion, we all realized that the game provides insight into possible barriers to achieving emissions goals, and how nations have to juggle meeting emission-reduction goals with their own economic self-interests. While the game takes more time to learn than Solutions, we decided it could still be very useful for students.
3. Carbon City Zero
We tried playing a free downloadable and printable version of Carbon City Zero, but it proved too time-consuming to learn the rules. After 45 minutes of struggling with the cards to figure out how to play, we gave up and moved on.
4. Somewhere Everywhere Water Rising
Family Pastimes, the company that makes Somewhere Everywhere Water Rising, is known for developing only collaborative games, and we have purchased many children's games from them in the past. In Somewhere Everywhere Water Rising, players take on the role of consultants who have to make collective decisions about developing land projects in the face of sea-level rise.
We liked the discussion it sparked, but ultimately concurred that the game specifically focuses on devastating sea-level rise, rather than systemic climate change that causes such rising levels in the first place. The game is easy to learn and relies on conversation, but we felt it had a lower educational value because it does not teach about the human activity that creates and perpetuates increasing global temperatures. The game might be more suitable as an extra credit activity, rather than the focus of a classroom lesson.
5. Nunami
Finally, we played Nunami, a lovely game created by an Inuit family from Ivujivik, Canada, with instructions in Inuktitut, English and French.
The game aims to teach players about balancing life in fragile terrain. There are cards for humans, animals, sand and snow. Although we deeply appreciated how the game strives to sensitize players to Inuit life on the tundra so that they can see what is threatened by climate catastrophe, it does not teach about the drivers of climate change and thus was not suitable for our specific classroom needs.
Picking the best
By 10 p.m., we had conquered the pizza, energetically played five different board or card games, and had a lot of fun discussing critical issues and meeting new people.
To our group, the clear "winner" is the board game Solutions because it encourages collaborating to make decisions with fact-based science. The setup of the game allows for interesting team-building conversations.
As I incorporate games into my courses on climate-change literature and first-year writing, students play Solutions and complete a writing assignment based on their various decisions during the game.
At our next climate change board game evening, my group of educators and activists plans to play Tipping Point, Daybreak, Carboniq and Climate Call.
Anyone want to join us? We'll deal you in.

In the 10,000 years since humans first developed animal agriculture, livestock farming has become central to modern society. Unfortunately, it's also become one of the biggest drivers of climate change and environmental destruction. Animal farms create a staggering amount of air, water and land pollution, and with the consequences of climate change worsening by the year, addressing the environmental impacts of livestock farming is more important than ever.
Global warming is an enormous part of climate change, but it's not the only part. The concept of climate change encompasses not only rising global temperatures, but all sorts of other changes to the natural composition of Earth and its atmosphere, such as water pollution and land degradation. Here are some of the ways livestock farming contributes to those changes.
But First, a Brief Summary of Greenhouse Gasses
One of the biggest ways livestock farming contributes to climate change is through the emission of greenhouse gasses, which trap heat in the Earth's atmosphere and cause global temperatures to rise. Insofar as livestock is concerned, there are three greenhouse gasses in particular of note.
- Carbon dioxide (CO2): The "main" greenhouse gas, carbon dioxide comprises around 80 percent of all greenhouse gas emissions. CO2 exists naturally in the atmosphere and regularly circulates from the Earth to the air as part of the carbon cycle; however, the burning of fossil fuels and other human activities releases additional CO2, throwing off that cycle and increasing global temperatures. CO2 can stay in the atmosphere for hundreds of years.
- Methane (CH4): Methane only accounts for 11 percent of global greenhouse emissions, and unlike CO2, disappears after a relatively brief 12 years. However, it's much more effective at trapping heat in the atmosphere: over a 100-year period, one pound of CH4 has 28 times the global warming potential as one pound of CO2.
- Nitrous oxide (N2O): Nitrous oxide only makes up six percent of greenhouse gas emissions, and exists naturally on Earth as part of the nitrogen cycle. It remains in the atmosphere for about 121 years on average after it's emitted, and its global warming potential is a whopping 265 times greater than that of CO2 over a 100-year period.
Because there are multiple greenhouse gasses with different warming potentials, greenhouse emissions are commonly converted to and measured in CO2-equivalents, or CO2-eq.
In various ways and to varying degrees, livestock farming emits all of the aforementioned greenhouse gasses. Here's how.
How Livestock Farming Creates Methane Emissions
Livestock are a significant source of methane emissions, thanks to a natural biological process called enteric fermentation. Cows, sheep, goats and other ruminant livestock have microbes in their digestive systems that decompose and ferment the food they eat, and
methane is a byproduct of this fermentation process.
That methane is released into the atmosphere when the animals burp or fart, and it's also contained in their urine and manure. One cow can produce up to
264 pounds of methane every year, and it's estimated that in total, enteric fermentation from ruminant livestock is responsible for 30 percent of
global anthropogenic methane emissions.
How Livestock Farming Leads to Pollution from Manure
Farm animals produce around
450 million tons of manure every year, and figuring out what to do with it is a major challenge for livestock farmers. Some farms
store manure in large piles, landfills or lagoons - known as "settlement ponds" - while others simply dump it onto cropland and use it as untreated fertilizer.
All of these management methods result in the release of methane and nitrous oxide, which manure also contains. When manure is stored in an environment with insufficient oxygen, as is often the case with landfills and lagoons, it undergoes a
process known as anaerobic decay, and releases nitrous oxide and methane into the air as a result. In addition, structural failures or extreme weather events often cause the
manure in settlement ponds to leak into nearby soil and waterways.
When manure is used as fertilizer, it releases nitrogen into the soil. That's the point of fertilizer, as plants need a certain amount of nitrogen to grow. But when farms use this type of fertilization as a disposal method for excess manure, they often over-apply it to the crops in question, which causes the soil to absorb more nitrogen than is necessary.
You might wonder why it matters if soil contains too much nitrogen. There are two intertwined reasons: nutrient runoff and soil erosion.
Nutrient Runoff
Nutrient runoff occurs when rain, wind or other environmental forces disrupt soil and carry it into nearby waterways. When that soil has been fertilized with untreated manure, it pollutes the water in question, both with nitrogen and other toxins that are common in manure, like phosphorus.
Nitrogen and phosphorus both stimulate algae growth, and excessive algae growth in a body of water leads to harmful algal blooms.
As their name implies,
harmful algal blooms have a host of damaging environmental consequences. They release toxins that kill aquatic life and poison the drinking water, which can cause serious illness
and even death in humans. Algal blooms reduce the amount of dissolved oxygen in the water, which aquatic life relies on, and prevent light from penetrating the water's surface, thus choking the life out of coral reefs and other aquatic plants that are crucial to Earth's ecosystems.
Soil Erosion
Nutrient runoff is exacerbated by another consequence of livestock farming: soil erosion. This is when topsoil particles become loosened and detached, which diminishes the quality of the soil and makes it much more susceptible to nutrient runoff.
A degree of soil erosion occurs naturally, but livestock farming greatly accelerates it in a few ways. One is overgrazing, which is when livestock graze on pastures for extended periods without the pastures being given time to recover.
The hooves of cows, goats and other ruminant livestock can erode the soil as well, especially when many of them are grazing in one place.
In addition to making nutrient runoff more likely,
eroded soil is less fertile and can support fewer forms of plant life. It is also worse at retaining water, which can
increase the risk of drought.
Deforestation Due to Livestock Farming
It's impossible to assess the environmental impacts of livestock farming without also discussing deforestation - the practice of permanently clearing out trees from forested land and repurposing the land for other uses.
Humans deforest around 10 million hectares of land every year, and
41 percent of tropical deforestation is carried out to make way for cattle pastures.
Deforestation is a monumentally damaging practice, and exacerbates all of the aforementioned impacts of livestock farming: greenhouse emissions, nutrient runoff and soil erosion.
Greenhouse Emissions Caused by Deforestation
When forested land is cut down, greenhouse emissions increase in two ways - one temporary, one permanent.
Trees absorb and store carbon dioxide from the atmosphere, which makes them an indispensable resource for reducing global temperatures. When they're cut down, however, all of that carbon dioxide is released back into the air. What's more, the absence of trees in a previously forested area means that, for an indefinite period of time, any atmospheric carbon dioxide that would otherwise have been sequestered by the trees remains in the atmosphere instead.
The greenhouse gasses emitted during livestock-driven deforestation, combined with the gasses emitted by livestock farms themselves, account for
11-20 percent of all greenhouse gas emissions worldwide. In the Amazon, which has traditionally been one of the world's largest sequesterers of carbon, so much land has been deforested that the rainforest is in danger of
becoming a net emitter of carbon instead.
Soil Erosion and Nutrient Runoff Caused by Deforestation
In forested land, trees play an important role in protecting and preserving the soil. The canopy they provide protects the soil from the sun and rain, while the trees' roots help hold the soil in place.
Needless to say, clearing all of the trees in a forested area means that the soil doesn't get any of these benefits. As a result, the soil becomes eroded even before any livestock might step foot on it, which in turn increases the likelihood of nutrient runoff and water pollution.
The Bottom Line
The environmental impact of livestock farming can't be ignored. The sector's contribution to deforestation, habitat loss and pollution of all kinds significantly exacerbates climate change. Absent a
significant reduction in global meat consumption, it will continue to present a formidable challenge to the long-term health of Earth and its many inhabitants.
