“…Warming is also raising the risk of algal blooms in populated tropical and subtropical regions (Fang et al., 2022). This process usually interacts with anthropogenic nutrient enrichment, exhibiting synergistic effects (Lin et al., 2023; Paerl & Scott, 2010), to cause resilience loss and regime shift toward the brink of ecological collapse (Zhang et al., 2018). Although not explicitly addressed in this study, human and climate factors likely interact to decline lake resilience because of eutrophication, algal blooming, and underwater light attenuation, which require further research to refine our understanding of the underlying mechanisms.…”

Strengthening aquatic resilience to prevent adverse shifts is critical for preserving global freshwater biodiversity and advancing Sustainable Development Goals. Nonetheless, understanding the long‐term trends and underlying causes of lake ecosystem resilience at a global scale remains elusive. Here, we employ an innovative framework, integrating satellite‐derived water quality indices with early warning signals and machine learning techniques, to investigate the dynamics of resilience in 1,049 lakes worldwide during 2000–2018. Our results indicate that 46.7% of lakes are experiencing a significant decline in resilience, particularly since the early 2010s, closely associated with higher human population density and anthropogenic eutrophication. In contrast, most lakes situated in alpine regions exhibit an increase in resilience, probably benefiting from climate warming and wetting. Together, this study provides a novel way to monitor lake resilience and predict undesired transitions, and reveals a widespread erosion in the ability of lakes to withstand stressors associated with global change.

“…However, global freshwater quality has deteriorated and algal blooms have increased in magnitude, frequency, and duration with the combined action of climate warming and human activities over the past decades [3][4][5][6]. Some harmful algal blooms can release harmful toxic and odor compounds, which have become a serious problem threatening human health and the stability of freshwater ecosystems [7,8]. Therefore, it is particularly important to adopt scientific strategies to prevent algal blooms and ensure the health of freshwater ecosystems and the safety of drinking water.…”

“…And it is expected that global algal blooms will continue to increase in the future due to climate warming and extreme climate events increasing [10,11]. However, the interacting mechanism between algal blooms and climate warming as well as freshwater eutrophication, which is a complicated bidirectional mechanism, is yet to be understood at present [8,[12][13][14]. It remains a key challenge we face to determine the potential action mechanisms of climate warming [8].…”

“…Some climate factors, such as temperature, wind, precipitation, solar radiation, and atmospheric pressure, have important effects on the proliferation of algae and the formation, expansion, and duration of blooms [22][23][24][25]. However, their exact action mechanism triggering and regulating the algal bloom remains largely unclear due to the scarcity of long-term continuous observations [8,26,27].…”

Global climate change can greatly promote the continuing expansion of algal blooms in eutrophic inland lakes. Wind fields, an important climate factor, provide an external driving force for the movement of algal blooms. Based on algal bloom satellite imageries and wind observation data from 2003 to 2022, this study explored a quantitative assessment of the variations in surface wind fields and their impacts on the algal blooms in Lake Taihu, China. The results indicate that the mean wind speed at different time scales in the Lake Taihu area presents a continuous descending tendency in recent decades, which is the probable cause for the increasing frequency and severity of algal blooms in the lake. Wind fields affect the formation, location, and severity of algal blooms in diverse and complex ways. The area and frequency of algal blooms in Lake Taihu increase with the decrease in wind speed. The 6 h mean wind speed before 12:00 LT (Local Time) on the day of the algal bloom occurrence generally follows a Gaussian distribution, with a wind speed range of (0.6 m/s, 3.4 m/s) at the 95.5% confidence level. Accordingly, the wind speeds of 0.6 m/s and 3.4 m/s are identified to be the lower and upper critical wind speed indicators suitable for the formation of algal blooms, respectively. Another meaningful finding is that the outbreak of large-scale algal blooms requires stricter wind speed conditions, with a significantly lower wind speed threshold of around 2 m/s. Our study also demonstrates that the dominant wind direction of southeast in the region may be an important cause of the continuous water-quality decline and the high frequency and severity of algal blooms in the northwest waters of the lake. These findings will contribute to further studies on the dynamic mechanism of algal blooms and provide support for water environment management and algal bloom prevention and control.
