2. the most common greenhouse gas
3. the adjustment or preparation of natural or human systems to a new or changing environment
4. a cycle that causes the earths orbit to get closer and further away from the sun
5. a type of fuel that was made under the ground millions of years ago
6. collecting and reprocessing a resource so it can be used again
7. the release of a substance/gas into the atmosphere
8. continually frozen ground that occurs when the temperature remains below 0 degrees for several years

Explanation:

This is a crossword puzzle related to climate - change concepts. Each clue corresponds to a term. For example, "The process plants use to make food where they take carbon dioxide out of the atmosphere and give out oxygen" (Across 2) is photosynthesis. "The greenhouse gas that comes from rotting rice and cows stomachs" (Across 7) is methane. "The process of cutting down the forests" (Across 11) is deforestation. "Refers to the average weather conditions over many years in a certain place" (Across 12) is climate. "A specific event or condition that happens over a period of hours or days" (Across 13) is weather. "The warmer periods between ice - ages" (Across 14) is interglacial.

For the Down clues: "When the carbon dioxide increases, the [blank] increases" (Down 1) is temperature (as more CO₂ leads to the greenhouse effect and warming). "A type of fuel that was made under the ground millions of years ago" (Down 6) is fossil fuel. "Collecting and reprocessing a resource so it can be used again" (Down 8) is recycling. "The release of a substance/gas into the atmosphere" (Down 9) is emission. "Continually frozen ground that occurs when the temperature remains below 0 degrees for several years" (Down 10) is permafrost. "The most common greenhouse gas" (Down 3) is carbon dioxide. "The adjustment or preparation of natural or human systems to a new or changing environment" (Down 4) is adaptation. "A cycle that causes the Earth's orbit to get closer and further away from the sun" (Down 5) is Milankovitch cycle.
