The impacts of climate change at 1.5C, 2C and beyond

The impacts of climate change at 1.5C, 2C and beyond

Carbon Brief has extracted data from around 70 peer-reviewed climate studies to show how global warming is projected to affect the world and its regions.

Scroll down to see how these impacts vary at different temperature levels, across a range of key metrics. Click on the icons below to skip to specific categories and regions.

All the research presented below compares impacts at 1.5C and 2C of warming above pre-industrial levels – the Paris Agreement’s temperature limits. These are shown in the first two columns, respectively.

If the research also includes a higher temperature level, such as 2.5C, 3C or 4C, this is shown in a third column. But this changes from one impact to the next, depending on the study.

Click or mouse over the on each section to see more information about each study, including any baseline period, which can differ between studies.

The reference for each metric can be found in square brackets beside the data – clicking on the number will link to the list of references at the end of the article. This is also where the methodology and link to the underlying data can be found.
