Inside Science Buzzwords:

1. Geoengineering  - The intentional change of the Earth’s environment in efforts to reduce climate change.
2. Aerosols - Tiny solid particles, such as dust or dirt, that stay in the atmosphere and reflect sunlight back into space.
3. Rayleigh scattering - The scattering of light as it moves through the atmosphere and is absorbed and radiated by the gas molecules in the air; this is reason the sky looks blue.
