Rapid lake ice structure changes across Swedish lakes puts public ice safety at risk
Lakes are rapidly losing ice under global warming, but little is known about ice structure changes. Ice structure is a key regulator of ice stability and thus safety, affecting activities on ice. Here, we analysed spatial and temporal variations in ice structure across 21 Swedish lakes, spanning from 55 to 69 °N, and over five decades. We found regional differences in ice structure, with fastest changes occurring in southern Sweden. The stable cl…
Toward a fundamental understanding of ecosystem metabolism responses to global warming
Science for society Countless bacteria, plants, animals, and other organisms that live in an ecosystem regulate how far an ecosystem is functioning as a net carbon sink or a net carbon source. A main question arises: how does this biologically driven regulation, often referred to as ecosystem metabolism, respond to global warming? To answer this question, which is not only important for the understanding of ecosystems being net carbon sinks or so…
Diel, seasonal, and inter-annual variation in carbon dioxide effluxes from lakes and reservoirs
Accounting for temporal changes in carbon dioxide (CO 2 ) effluxes from freshwaters remains a challenge for global and regional carbon budgets. Here, we synthesize 171 site-months of flux measurements of CO 2 based on the eddy covariance method from 13 lakes and reservoirs in the Northern Hemisphere, and quantify dynamics at multiple temporal scales. We found pronounced sub-annual variability in CO 2 flux at all sites. By accounting for diel vari…

Effects of Changes in Arctic Lake and River Ice
Arctic Freshwater Ice and Its Climatic Role
Lakes and reservoirs as regulators of carbon cycling and climate
We explore the role of lakes in carbon cycling and global climate, examine the mechanisms influencing carbon pools and transformations in lakes, and discuss how the metabolism of carbon in the inland waters is likely to change in response to climate. Furthermore, we project changes as global climate change in the abundance and spatial distribution of lakes in the biosphere, and we revise the estimate for the global extent of carbon transformation…
Adapting regional eutrophication targets for surface waters—influence of the EU Water Framework Directive, national policy and climate change
Warmer Winters
Winters in Sweden have become warmer in the 1990s, and as a consequence the timing of ice break-up and the growth and decline of spring phytoplankton has shifted, starting earlier. Even spring temperatures have become warmer, leading to an earlier beginning of the summer phytoplankton growth. The spring-ward shift in phytoplankton population growth has resulted in an extension of the growing season by at least one month. Although mean total phyto…
