Answered by GPT-4o mini
The two greenhouse gases that are at an all-time high are **carbon dioxide (CO₂)** and **methane (CH₄)**. These gases have been increasing due to human activities such as fossil fuel combustion, deforestation, and agricultural practices. Oxygen (O₂) is not a greenhouse gas and does not contribute to the greenhouse effect.
