Test WG summary module GPWG2


The Global Paleofire Working Group 2 (GPWG2) was active from 2016 to 2019. It developed and analysed fire history records using the Global Charcoal Database (GCD) in order to understand what controls fire and its impacts on a wide range of spatial and temporal scales. The group employed diverse data sources, an open-access database, statistical tools, and models.

- Understand how and why fire history has varied in different biomes since the last glacial period.
- Identify best practices for using fire history data to inform modern risk assessment and management practices.
- Use data and models to understand how changing disturbance regimes alter species composition and distributions under changing climate and land-use conditions.
- Integrate diverse datasets and models to understand how human activities and climate changes shape and respond to changing fire patterns.

Key findings

- Fire has generally increased as global temperatures have warmed since the Last Glacial period, especially in temperate latitudes.
- The spatial expression of burning has become much more variable throughout the Holocene, as humans increasingly altered fire regimes.
- A key challenge for scientists using sediment-based fire-history reconstructions is to conduct more calibration studies, so that fire history changes can be better quantified.
