Short summary
Short summary
We developed a simple way to predict how much dissolved organic carbon moves from soils into streams, and what types of carbon are present, using widely available data. By analysing 150 small catchments across Great Britain, we found that peat-rich landscapes release more carbon, especially forms that are resistant to breakdown, while farmland releases less and simpler forms. These patterns can be mapped at large scales, helping improve carbon cycle estimates and support water management.

Short summary
Short summary
Many peatlands around the world are eroding and causing carbon losses to the atmosphere and to freshwater systems. To accurately report emissions from peatlands we need to understand how much of the eroded peat is converted to CO2 once exposed to the atmosphere. We need more direct measurements of this process and a better understanding of the environmental conditions that peat is exposed to after it erodes. This information will help quantify the emissions savings from peatland restoration.

In this paper, we identify potential negative social tipping points linked to Earth system destabilization and draw on related research to understand the drivers and likelihood of these negative social tipping dynamics, their potential effects on human societies and the Earth system, and the potential for cascading interactions and contribution to systemic risks.

Short summary
Short summary
Lakes worldwide are changing and under threat due to stressors such as overload of nutrients, increased input of organic carbon (“browning”), and climate change, which may cause reduced water volume, salinization, or even loss of waterbodies. Some of these changes are abrupt to the extent that they can be characterized as tipping points for that particular system. Such changes may also cause increased release of greenhouse gases, and lakes are major players in the global climate in this context.

Short summary
Short summary
Peatlands have been subject to a range of land management regimes over the past century. This has affected the amount of carbon that drains into surrounding streams and rivers. In our study, we measured carbon concentrations in streams draining from drained, non-drained, and restored areas of the Flow Country blanket bog in N Scotland. We found that drained peatland had higher concentrations and fluxes of carbon relative to non-drained areas. Restored peatland areas were highly variable.

Short summary
Managing drinking water catchments to minimise water colour could reduce costs for water companies and save their customers money. Brown-coloured water comes from peat soils, primarily around upland reservoirs. Management practices, including blocking drains, removing conifers, restoring peatland plants and reducing burning, have been used to try and reduce water colour. This work brings together published evidence of the effectiveness of these practices to aid water industry decision-making.
