The Earth is getting warmer due to gases like CO2 from human activities, like burning fossil fuels. People from different countries agree on this and aim to limit the global temperature rise. The article talks about various gases causing the warming, where they come from, and how some countries agreed to reduce these emissions. To fight global warming, new technologies capture CO2 from big sources and even directly from the air, turning it into useful products like fuels and chemicals. These actions are essential to meet the global goal of keeping the temperature rise below 2°C compared to before industries began affecting the climate. So, it's crucial to act now to decrease gas emissions and combat global warming effectively.
