In temperate Europe, fire is already here: The case of The Netherlands.

Landscape fires are usually not associated with temperate Europe, yet not all temperate countries record statistics indicating that actual risks remain unknown. Here we introduce new wildfire statistics for The Netherlands, and summarize significant events and fatalities. The period 2017-2022 saw 611 wildfires and 405 ha burned per year, which Copernicus' European Forest Fire Information System satellite data vastly underestimate.

New land-use-change emissions indicate a declining CO airborne fraction.

About half of the anthropogenic CO emissions remain in the atmosphere and half are taken up by the land and ocean. If the carbon uptake by land and ocean sinks becomes less efficient, for example, owing to warming oceans or thawing permafrost, a larger fraction of anthropogenic emissions will remain in the atmosphere, accelerating climate change. Changes in the efficiency of the carbon sinks can be estimated indirectly by analysing trends in the airborne fraction, that is, the ratio between the atmospheric growth rate and anthropogenic emissions of CO (refs.

Fire and deforestation dynamics in Amazonia (1973-2014).

Consistent long-term estimates of fire emissions are important to understand the changing role of fire in the global carbon cycle and to assess the relative importance of humans and climate in shaping fire regimes. However, there is limited information on fire emissions from before the satellite era. We show that in the Amazon region, including the Arc of Deforestation and Bolivia, visibility observations derived from weather stations could explain 61% of the variability in satellite-based estimates of bottom-up fire emissions since 1997 and 42% of the variability in satellite-based estimates of total column carbon monoxide concentrations since 2001.
