Adaptation to climate change in Finland : Current state and future prospects

The KOKOSOPU project has aimed at a comprehensive evaluation of the national adaptation policy with particular emphasis on the National Adaptation Plan and international policy development. In addition, future challenges related to societal development have been taken into account. Projections of climate change, Finland’s Climate Act and the strengthened adaptation policy in the EU emphasise the importance of the national adaptation policy. A key objective of the National Adaptation Plan 2014–2022 was to strengthen the adaptive capacity of Finnish society. This objective is still relevant. The conditions for reaching the objective have, however, partly changed. First, cross border consequences of climate change are increasingly emphasised. Second, issues of justice and fairness with respect to the consequences of climate change and adaptation actions are being identified as central. Third, greater weight is given to the overall sustainability of adaptation and climate action. The changing conditions for climate change adaptation should be reflected in the allocation of resources, in improved coordination within the administration and in co-operation between the public and private sector. In addition, knowledge and education should be enhanced, and resources provided for RDI, and for monitoring and evaluation that supports continued improvement of adaptation activities

Ilmastonmuutokseen sopeutuminen Suomessa – nykytila ja kehitysnäkymät

KOKOSOPU-hankkeen tavoitteena oli tuottaa kokonaisarvio kansallisen sopeutumispolitiikan edistymisestä erityisesti kansallisen sopeutumissuunnitelman valossa ja kansainväliseen kehitykseen verraten. Lisäksi tarkasteltiin niitä haasteita, jotka tuleva ilmastollinen ja yhteiskunnallinen kehitys asettavat sopeutumistoiminnalle. Ennakoitu ilmastonmuutoksen eteneminen, Suomen ilmastolaki ja EU:n sopeutumispolitiikan vahvistuminen korostavat kansallisen sopeutumissuunnitelman merkitystä. Vuosien 2014–2022 sopeutumissuunnitelman keskeisenä tavoitteena oli suomalaisen yhteiskunnan sopeutumiskyvyn vahvistaminen. Tämä tavoite on edelleen ajankohtainen. Tavoitteen saavuttamisen lähtökohdat ovat kuitenkin osittain muuttuneet. Ensinnäkin globaalit ja rajoja ylittävät vaikutukset korostuvat. Toiseksi ilmastonmuutoksen vaikutusten ja niihin sopeutumiseen tarvittavien yhteiskunnallisten muutosten oikeudenmukaisuus on nousemassa keskiöön. Kolmanneksi sopeutumistoiminnan ja ilmastotyön kokonaiskestävyyteen kiinnitetään aikaisempaa enemmän huomiota. Sopeutumistoiminnan muuttuneen toimintaympäristön tulee näkyä resurssien kohdentamisena ja parempana koordinointina hallinnossa sekä hallinnon ja yksityisen sektorin välillä. Tarvitaan myös lisäpanostusta osaamiseen ja koulutukseen, tutkimus-, kehittämis- ja innovaatiotoimintaan sekä jatkuvaan edistymistä tukevaan seurantaan ja arviointiin.Tämä julkaisu on toteutettu osana valtioneuvoston selvitys- ja tutkimussuunnitelman toimeenpanoa.

Revealing fine-scale variability in boreal forest temperatures using a mechanistic microclimate model

Fine-scale temperatures are important drivers of ecosystem functions and biodiversity in boreal forests. However, accounting for large thermal variability has been difficult due to the coarse spatiotemporal resolution of climate data that is commonly applied in studies of biodiversity and forest health. Here, we use a mechanistic microclimate model and geospatial environmental and weather data to reveal microclimate temperature variability in a broad macroclimatic gradient in boreal forest environments. We modelled hourly near-surface temperatures (0.15 m above ground) in May-August 2020 over three focus areas located in hemiboreal, southern boreal and northern boreal forest zone in Finland at a spatial resolution of 10 m x 10 m. A comparison against data from 150 microclimate stations showed reasonable agreement (root mean square error [RMSE] 2.9 °C) between the measured and modelled temperatures. RMSE for the three focus areas ranged 2.2 –3.2 °C, and the difference was found to be generally smaller under dense canopies compared to open areas. The modelling revealed substantial thermal variability over the landscapes; for example, seasonal near-surface temperature ranges varied 26.5 °C – 42.9 °C, with the variation being smallest in the hemiboreal landscape with multiple large waterbodies, and largest in southern boreal landscape with large wetland areas. These results demonstrate the great potential of mechanistic microclimate modelling to increase our understanding of the thermal characteristics of various boreal forest environments. Ultimately, high-resolution spatiotemporal microclimate data will permit better understanding of e.g., boreal species distribution under climate and land use change and fine-scale variability in disturbances, including insect pests and forest fires.peerReviewe

Microclimate, an inseparable part of ecology and biogeography

Abstract Microclimate science has developed into a global discipline. Microclimate science is increasingly used to understand and mitigate climate and biodiversity shifts. Here, we provide an overview of the current status of microclimate ecology and biogeography, and where this field is heading next. We showcase the recent advances in data acquisition, such as novel field sensors and remote sensing methods. We discuss microclimate modelling, mapping, and data processing, including accessibility of modelling tools, advantages of mechanistic and statistical modelling, and solutions for computational challenges that have pushed the state-of-the-art of the field. We highlight the latest research on interactions between microclimate and organisms, including how microclimate influences individuals, and through them populations, communities, and entire ecosystems and their processes. We also briefly discuss recent research on how organisms shape microclimate from the tropics to the poles. Microclimates are also important in ecosystem management under climate change. We showcase new research in microclimate management with examples from biodiversity conservation, forestry, and urban ecology. We discuss the importance of microrefugia in conservation and how to promote microclimate heterogeneity. We identify major knowledge gaps that need to be filled for further advancing microclimate methods, investigations, and applications. These gaps include spatiotemporal scaling of microclimate data, mismatches between macroclimate and microclimate in predicting responses of organisms to climate change, and the need for more evidence on the outcomes of microclimate management. &nbsp; Biosketch The authors are participants of the Microclimate Ecology and Biogeography conference held in Antwerp, Belgium in 2022.

Microclimate, an important part of ecology and biogeography

Brief introduction: What are microclimates and why are they important?: Microclimate science has developed into a global discipline. Microclimate science is increasingly used to understand and mitigate climate and biodiversity shifts. Here, we provide an overview of the current status of microclimate ecology and biogeography in terrestrial ecosystems, and where this field is heading next. Microclimate investigations in ecology and biogeography: We highlight the latest research on interactions between microclimates and organisms, including how microclimates influence individuals, and through them populations, communities and entire ecosystems and their processes. We also briefly discuss recent research on how organisms shape microclimates from the tropics to the poles. Microclimate applications in ecosystem management: Microclimates are also important in ecosystem management under climate change. We showcase new research in microclimate management with examples from biodiversity conservation, forestry and urban ecology. We discuss the importance of microrefugia in conservation and how to promote microclimate heterogeneity. Methods for microclimate science: We showcase the recent advances in data acquisition, such as novel field sensors and remote sensing methods. We discuss microclimate modelling, mapping and data processing, including accessibility of modelling tools, advantages of mechanistic and statistical modelling and solutions for computational challenges that have pushed the state‐of‐the‐art of the field. What's next?: We identify major knowledge gaps that need to be filled for further advancing microclimate investigations, applications and methods. These gaps include spatiotemporal scaling of microclimate data, mismatches between macroclimate and microclimate in predicting responses of organisms to climate change, and the need for more evidence on the outcomes of microclimate management
