  • The forest limits of south-east Norway have expanded to higher altitudes. Two main processes are believed to cause these changes : regrowth after abandonment of human utilisation and recent climate changes. To separate the effects of these 2
  • processes, 4 datasets have been used : climate data, downscaled climate change scenario data, forest height growth, and 4 vegetation maps. The maps represent the years 1959 and 2001, potential natural vegetation (PNV), and a climate change scenario (CCS
  • ). The recent upper potential climatic and edaphic forest limit (UPCEFL) was used to define the potential for forest regrowth after the abandonment of human utilisation. Forest height growth and climate data were then used to analyse any supplementary effect
  • of recent climate change. The results show that raised forest limits and forest range expansion often attributed to recent climate change is rather the product of regrowth, a process that was climatically retarded from 1959 to 1995. For the period 1995-2006
  • , the data indicate a preliminary effect of climate change escalating the regrowth and probably pushing the future forest limits to higher altitudes.

  • Assessing climate change in the contiguous United States using a modified Thornthwaite climate classification scheme

  • Climate ; Climate classification ; Climatic change ; Moisture ; Multivariate analysis ; Temperature ; United States of America
  • This new approach allows both moisture and thermal conditions to be examined simultaneously for a better assessment of multivariate climate change. Changes in area of different climate types over time is determined using the climate year approach
  • and the spatial nature of climate change is examined by computing climate types based on averages from three thirty-year periods over the twentieth century. Over the study period from 1895 to 2005, statistically significant changes in areal coverage of different
  • climate types have occurred : changes to moister climate categories and positive temperature trends.

  • Changement climatique ; Climat ; Concept ; Connaissance ; Enseignement ; Etats-Unis ; Perception ; Variabilité climatique
  • Climate ; Climatic change ; Climatic variability ; Concept ; Knowledge ; Perception ; Teaching ; United States of America
  • This special issue stems from the need to highlight the widespread misconceptions about climate science in general, and to present successful strategies from which we can learn as we strive toward a climate-literate citizenry. One of the challenges
  • to climate literacy lies in the understanding or perceived understanding of the term climate. In recent times, the subtle distinction between weather vs. climate, climate variability vs. change, and natural vs. anthropogenic forcings appears to have been lost
  • . The disconnect between actual climate science knowledge and perceived knowledge is pervasive in nature and global in extent. This special issue is a timely one that captures the state of knowledge concerning climate literacy at a critical watershed moment.

  • Changement climatique ; Climat ; Education ; Enseignement ; Etats-Unis ; Information ; Service climatique ; Stratégie d'acteurs ; Vulnérabilité
  • Climate ; Climatic change ; Decision making process ; Education ; Information ; Teaching ; United States of America ; Vulnerability
  • The prospect of climate change is driving a renewed effort within the scientific community to develop a system of climate services to inform decision-makers about the potential impacts of climate change. Climate literacy is part of a coordinated
  • effort to make people more aware of their natural environment and factors, both natural and anthropogenic, that cause disruptions to that environment. A more informed user is a more effective user; this concept lies at the heart of climate services
  • . This paper concludes with an examintion of the importance of climate literacy as a component of a U.S. National Climate Service.

  • The AA. present some examples of the influence of climate and climate anomalies on the alpine environment in the Ortles-Cevedale Group, OCG, focusing on the different responses of Norway spruce tree-ring growth from one OCG valley (the Trafoi Valley
  • ) and of the glaciers from the same region. Spruce responses to the climate anomaly of 2003 were more evident with a one-year lag. Glacier mass loss in the OCG in 2003 was the highest since yearly measurement started. The examples reported confirm the strong and even

  • Statistical analysis of a multi-centennial dendrochronological proxy dataset of regional climate, constructed across the latitudinal gradient of 1000 km, was performed. It was shown that centennial (c. 100 year), tri-decadal (27-32 year), bi-decadal
  • (17-23 year) and decadal (9-13 year) periodicities governed the climate variability in Finland over the last five centuries. Despite the fact that many of the climatic periodicities bore great resemblance to periodicities of solar cycles, little
  • evidence of actual solar influence on Finnish climate was found.
