We investigated the role of knowledge of climate tipping points on public climate risk perceptions in Norway. We did this by conducting a national survey of a representative sample of the population. We found a low level of public knowledge of climate tipping points amongst our participants and that exposure to knowledge of climate tipping points did affect climate risk perceptions to a limited degree.

Short summary
In this work, we draw on paleoreords, observations and modelling studies to review tipping points in the ocean overturning circulations, monsoon systems and global atmospheric circulations. We find indications for tipping in the ocean overturning circulations and the West African monsoon, with potentially severe impacts on the Earth system and humans. Tipping in the other considered systems is considered conceivable but currently not sufficiently supported by evidence.

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.

Short summary
Tipping points are abrupt, rapid and sometimes irreversible changes and numerous approaches have been proposed to detect them in advance. Such approaches have been termed early-warning signals and represent a set of methods for identifying changes in the underlying behavior of a system across time or space that would be indicative of an approaching tipping point. Here we review the literature to find where, how, and which early-warnings have been used so far in real-world case studies.

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
We use an Earth system model with two new ocean ecosystem features (plankton size traits and temperature-sensitive nutrient recycling) to revaluate the effect of climate change on sinking organic carbon (the
biological pump) and the ocean carbon sink. These features lead to contrary pump responses to warming, with a combined effect of a smaller sink despite a more resilient pump. These results show the importance of including ecological dynamics in models for understanding climate feedbacks.

Short summary
Water companies in the UK have found that drinking water from upland reservoirs is becoming browner. This is costly to treat and if the dissolved organic matter that causes the colour isn't removed potentially harmful chemicals could be produced. Land management around reservoirs has been suggested as a way to reduce water colour. We reviewed the available literature to assess whether this would work. There is limited evidence available to date, although forestry appears to increase colour.

Water authorities responsible for water quantity and water quality management may strongly influence the magnitude of greenhouse gas emissions from surface waters and adjacent peat areas within their territories.
In a case study of the Dutch Water Authority Amstel, Gooi and Vecht it is estimated that these emissions are about 10 times higher than the climate footprint of the operational management of the water authority.

Short summary
Commonly used nitrogen fertilisers, ammonium nitrate, urea and urea coated with a urease inhibitor, were applied to experimental plots. Fertilisation with ammonium nitrate supported the largest yields but also resulted in the largest nitrous oxide emissions. Urea was the largest emitter of ammonia. The coated urea did not significantly increase yields; however, ammonia emissions were substantially smaller than urea. The coated urea was the best environmentally but is economically unattractive.

This study uses statistical analyses to look for signs of declining resilience (i.e. greater sensitivity to small shocks) in the global carbon cycle and climate system across the Palaeocene–Eocene Thermal Maximum (PETM), a global warming event 56 Myr ago driven by rapid carbon release. Our main finding is that carbon cycle resilience declined in the 1.5 Myr beforehand (a time of significant volcanic emissions), which is consistent with but not proof of a carbon release tipping point at the PETM.

The differential effects of the aquatic plants on greenhouse gas fluxes may be due to plant density and whether or not the plant roots can access the sediment. We therefore looked into the effect of these two variables on water hyacinth greenhouse gas balance using a laboratory experiment. We found that greenhouse gas dynamics were strongly influenced by plant density and rooting. Our findings pinpoint management options that can optimize carbon sequestration and minimize CH4 emissions.

Short summary
Hydroelectric reservoirs in the tropics emit greenhouse gases but also bury carbon in their sediments. We investigated the efficiency of organic carbon (OC) burial in a large tropical reservoir, using spatially resolved measurements of sediment accumulation, and found that more than half (~ 57 %) of the OC deposited onto the sediment is buried. This high efficiency in OC burial indicates that tropical reservoirs may bury OC more efficiently than natural lakes.

Short summary
While pristine, growing peatlands are often considered to be net sinks of carbon dioxide (CO2), fluxes vary considerably and these systems can be net sinks or sources of CO2. To explain part of this huge variation, here we present a phenomenon of peat moss (Sphagnum)-driven CO2 production. Due to the acid excreted by Sphagnum, bicarbonate in the surface water is transformed into CO2. Thus, while these systems have high CO2 fixation rates due to growing Sphagnum, they show a net emission of CO2.

Short summary
We disentangled two major factors that affect lake water quality, namely the meteorological conditions and loading from the catchment.
In previous studies, distinction of these two major factors was not always sought.
However, from the management point of view, quantifying these two factors may be of interest, for example because the managers may want to evaluate the effectiveness of an abatement plan that reduced catchment loading despite the unfavourable meteorological conditions.

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.
