Burning fossil fuels releases carbon dioxide, a major contributor to the greenhouse effect.
If all the carbon dioxide emitted by humans had accumulated on Earth, humanity might have already been extinct.
Fortunately, nature has absorbed human-created carbon dioxide through forests and swamps.
However, since the Industrial Revolution, the amount of carbon dioxide emitted by humans has exceeded nature's absorption capacity, and unabsorbed carbon dioxide remains and accumulates in the atmosphere.
This accumulated carbon dioxide has become a decisive factor in raising the Earth's temperature by trapping geothermal heat within the atmosphere.
Currently, the world emits approximately 50 billion tons of greenhouse gases and is pursuing carbon neutrality policies to address the climate crisis.
It is important to examine where and how much greenhouse gases are emitted and develop reduction measures tailored to each sector.

Learning Help
1.
Adjust game difficulty
Teachers can select appropriate cards based on the students' level, and can lower the difficulty level by collecting only five types of climate cards instead of all six.
After playing the game, discuss any difficult or incomprehensible parts of the climate cards and have the teacher explain them.


2.
Try out different games
The Climate Card Collector's Edition basically allows you to collect 3 climate cards.
In the basic game, you can collect an infinite number of climate cards, and the game ends when you collect all of them. However, you can modify the rules to allow you to collect up to 3 climate cards at a time, and discard any additional climate cards collected.


3.
Additional effects of the game
Since COVID-19, our mutual interest and emotional bonds have weakened.
The game becomes more intimate as participants repeatedly call out each other's names, saying things like "Do you have ○○ climate?" to obtain cards.
Also, make sure that you don't continue to favor just one person.


4.
Use the Notes and Memory Aids
To prevent one student from being singled out too often, a rule can be set that prohibits the same person from being singled out three times in a row, and the game can be played while recording the information on a memory aid board for those who have trouble remembering.


5.
Performance evaluation and related activities
The game includes the characteristics of the world's climates as well as environmental issues that appear in each climate zone.
You can have students present or write reports on climate change by linking climate-specific characteristics and environmental issues to climate change. You can also try an additional activity of discovering climate-specific environmental issues not presented in the game and making them into cards.

Game Preparation (by Group)

1.
Settings
Shuffle the carbon cards to make a pile.

2.
start
The game order is determined through rock-paper-scissors, etc.
Move to the right or left of the first player.


Game progress

3.
game
1) Shuffle the carbon cards (including the new start card) into piles and receive 6 cards each.

· You can discard a new start card. (You can freely discard a new start card after any card.)
· If a new start card is spread out on the floor, you can discard any card you want.
· After the Carbon Emission 0 card, you must discard a 50 card or a Fresh Start card.
· If you have no cards to discard, you must take one card from the pile.

· (Declaration of surrender) Give up the game by receiving a penalty equal to the sum of the points of the carbon cards you hold in your hand.
4) Game End Conditions: The game ends when at least one player puts down all the cards in their hand or declares surrender, leaving the player with only one player.

· Anyone who puts down all their cards receives a Carbon Zero (Carbon -100 points) card as a bonus.
· A person who declares surrender receives a penalty equal to the sum of the carbon card points held in his or her hand.
· All cards that cannot be discarded are penalized, and new start cards that cannot be discarded are counted as 100 penalty points.
