Title: Statistical downscaling and projection of climatic extremes using machine learning algorithms
Journal: Theoretical and Applied Climatology
DOI: https://doi.org/10.1007/s00704-023-04532-y
Abstract: Climate change impacts all fields of life including agriculture. This study aimed to determine the historical and future climatic variations for the rainfed Prince Edward Island (PEI). Statistical downscaling model (SDSM), and support vector regression (SVR), multilayer perceptron (MLP), and random forest (RF) algorithms were applied to downscale climatic extremes, i.e., daily precipitation, maximum temperature (Tmax), and minimum temperature (Tmin) at 8 meteorological stations across the island for the baseline period (1976–2003). The MLP algorithm was further applied to project the climatic extremes for the future period (2006–2100) under three representative concentration pathways (RCP 2.6, RCP 4.5, and RCP 8.5) due to its better performance. Linear scaling was used to reduce the biases from the outputs of MLP. The annual and seasonal (potato growing season of May to October) outputs revealed that Tmax and Tmin are expected to increase in the future under all the RCPs, with the maximum increment observed for RCP 8.5. The increments in Tmax and Tmin for the growing season were 0.72–5.37 °C and 0.87–5.91 °C, respectively, irrespective of the RCPs. The spatial pattern of average annual precipitation in the growing season showed high (578–966 mm), moderate (558–625 mm), and low (449–664 mm) precipitation at the eastern, central, and western parts of PEI for both baseline and future periods. The highest changes were observed under RCP 8.5 as the warmest climate associated with this scenario. The projected precipitation extreme indices trends are likely to increase in the future. The maximum changes/year were observed under RCP8.5, which are 1.20 days/year for days with heavy precipitation (R10mm), 2.44 days/year for the days with very heavy precipitation (R20mm), 7.60 mm/year for total precipitation from heavy rainy days (R95p), 3.76 mm/year for total precipitation from very heavy precipitation days (R99p), 1.10 days/year for continuous wet days (CWD), and 0.08 mm/day for precipitation intensity (SDII) for a year. The findings of this study will help the farmers and government policymakers to get a clear picture of the climatic variability and strategize to mitigate the climate change impact on the island’s agriculture in the future.

Title: Reporting evidence on the environmental and health impacts of climate change on Indigenous Peoples of Atlantic Canada: a systematic review
Journal: Environmental Research: Climate
DOI: https://doi.org/10.1088/2752-5295/accb01
Abstract: While evidence of Indigenous Peoples’ climate knowledge and adaptation practices is readily available in Canada, regional variations are poorly understood, and proper representation and recognition in academic and planning contexts is scarce. Much less still is known about the health and environmental impacts of climate change on these communities. This review sought to report and assess the evidence of such impacts on Indigenous Peoples in Atlantic Canada over the past two decades. Current published studies focused on Indigenous Peoples’ knowledge and perceptions and highlight government policy for adaptation measurements. We systematically searched publications between January 2002 and March 2022 from the Web of Science, PubMed, Google Scholar, and Science Direct databases, screening for (1) environmental and (2) health impacts of climate change on Indigenous Peoples. Fifty-six articles were selected and thoroughly reviewed using the GRADE approach to assess the quality of the evidence. The quality of evidence ranged from low to moderate, and the evidentiary foundation for links between climate change and health effects was weak. We thus find an opportunity for future research to focus on climate-related effects on the health and lands of Indigenous Peoples within Atlantic Canada, especially concerning impacts on mental health.
