Climate scientists often use the gigaton (one billion tons) to measure greenhouse gas emissions, glacier melt, and other chemical changes related to global climate. The gigaton is a unit of measure with few practical applications.
- Carbon removals: How to scale a new gigaton industryPotential benefits. Increase biodiversity; improve water quality; reduce flood risks; eco-tourism. Potential challenges. Release of some greenhouse gases via restoration; uncertain permanence level; long-term monitoring and management. Nature-based removals. 2. Cropland, grassland, and agroforestry.
- Gigatonne - Energy EducationA gigatonne is 1,000,000,000 tonnes, and is often used when discussing human carbon dioxide emissions. This is roughly the mass of all land mammals (other than humans) in the world as per the XKCD comic strip to the right. It's also roughly twice the mass of all of the people in the world.

Satellite data show that Greenland and Antarctica are losing mass at a rate of 283 gigatonnes per year and 145 gigatonnes per year, respectively. So how big is just one gigatonne? Central Park.
- Demystifying the Gigaton – Understanding Billions of Metric TonsFirst things first – a gigaton, sometimes abbreviated as Gt, is equivalent to: 1 billion metric tons. 1,000,000,000 metric tons. 1 petagram. So in the International System of Units (SI), the prefix "giga" means one billion (10^9). Just like how a gigabyte represents a billion bytes.
