How much will the average temperature of the planet increase? That depends on us. First, remember that making projections about the future, especially for something as complex as the entire Earth’s ecosystem, is challenging. As scientists measure more and more data points, they become more confident about the accuracy or likelihood of their predictions. Most projections of future temperatures present several scenarios, the course we are currently on (also known as the “business as usual” scenario), then projections of temperature increases based on collective action humanity may take to reduce greenhouse gas (GHG) emission that cause climate change. Below is an example of this from Climate Action Tracker.

If current policies are fully implemented and work as hoped, the planet is projected to still warm between 2.8 – 3.2° C above pre-industrial levels by 2100. That is still dangerously warmer than in any conditions humans have ever lived.
