How much have temperatures risen in countries across the world? Explore country-by-country data on monthly temperature anomalies.

Addressing vulnerability and promoting security
Mar 19, 2024 | Our World in Data

In 2015, countries across the world adopted the Paris Agreement, agreeing on a goal to limit global warming “well below 2°C” above pre-industrial temperatures while “pursuing efforts” to limit warming to 1.5°C. These targets are set based on the rise in the global average temperature. That’s the metric that most organizations use to track our global climate trajectory. We present these global time series on Our World in Data. However, climate change does not affect all areas of the globe uniformly. Some regions are warming faster than others, which matters for local ecosystems, weather patterns, and human impacts. To allow people to track temperature changes across the globe, we've made this data explorable at the national level. We have relied on the excellent data from the European Centre for Medium-Range Weather Forecasts (ECMWF) ERA-5 project to do this.  

This comprehensive dataset provides high-resolution (31-kilometer square) climate records that include a wide range of atmospheric, ocean-wave, and land-surface variables. We’ve used its 2-meter air surface temperature records, which include measurements across land, sea, and inland waters. The ERA5 data is structured in a gridded format. We’ve converted this into country-level data using the World Bank's country outlines, making adjustments for geographical disparities from Earth’s curvature. I’ve included some extra details on our methods in the footnotes.  

Our World in Data will update this article monthly with new data.
