As mudancas climaticas ja sao realidade e os relatorios do Painel Intergovernamental sobre Mudancas Climaticas (IPCC) deixam claro que mudancas aceleradas vem sendo observadas apos a revolucao industrial, em funcao de atividades antropogenicas. Variacoes climaticas significativas podem mudar as caracteristicas fisicas atuais, impor restricoes de ocupacoes e impactar os setores ambiental, social e economico. Com clima quente e seco, a mesorregiao Norte de Minas Gerais se mostra fragil as mudancas climaticas. Importantes atividades economicas como agricultura, pecuaria, agroindustrias e usinas hidreletricas estao relacionadas as condicoes climaticas. A ocupacao por populacoes com perfil socioeconomico limitado coloca a mesorregiao em situacao de vulnerabilidade. Neste estudo sao mostradas as projecoes futuras de temperatura e precipitacao, considerando um Modelo Climatico Regional forcado por dois diferentes Modelos Climaticos Globais fornecidos pelo Coordinated Regional Climate Downscaling Experiment (CORDEX) , para medio prazo (2041-2070) e longo prazo (2071-2100) em dois cenarios climaticos Representative Concentration Pathways (RCPs) , assumindo maiores (RCP 8.5) ou menores (RCP 4.5) emissoes de Gases de Efeito Estufa (GEE). Os modelos projetam aumento da temperatura em ate 4oC a medio prazo e ate 5oC a longo prazo, sendo mais intenso na primavera. Os modelos estimam secas no outono e inverno, chuvas de ate 1000mm no verao e entre 400 e 800mm na primavera, com consideravel variacao espacial. Os efeitos dessas alteracoes sao potenciais para atingirem os setores agropecuario, energetico e industrial, a qualidade de vida e saude das populacoes e a economia em nivel regional. A implementacao de medidas de mitigacao e adaptacao ao clima sao desafiantes para populacoes com economias pouco desenvolvidas, como as do Norte de Minas. Palavras–chave: Mudancas climaticas. Modelos climaticos regionais. Temperatura e precipitacao. Vulnerabilidade. Mesorregiao Norte de Minas Gerais. Climate change is already a reality, and the reports of the Intergovernmental Panel on Climate Change (IPCC) make it clear that accelerated changes have been observed following the industrial revolution as a result of anthropogenic activities. Significant climatic variations can change current physical characteristics, impose technical constraints, and impact the environmental, social, and economic sectors. With a hot and dry climate, the northern mesoregion of Minas Gerais is fragile to climate change. Principal economic activities such as agriculture, livestock, agribusiness and hydroelectric plants are related to climatic conditions. The occupation by populations with a limited socioeconomic profile places the mesoregion in a situation of vulnerability. In this study the future projections of temperature and precipitation are shown, considering a Regional Climatic Model forced by two different Global Climate Models provided by the Coordinated Regional Climate Downscaling Experiment (CORDEX), medium term (2041-2070) and long term (2071-2100 ) in two Representative Concentration Pathways (RCPs) climatic scenarios, assuming larger (RCP 8.5) or lower (RCP 4.5) greenhouse gas (GHG) emissions. The models project a temperature increase of up to 4oC in the medium term and up to 5oC in the long term, being more intense in the spring. The models estimate droughts in autumn and winter, rainfall up to 1000mm in summer and between 400 and 800mm in spring, with considerable spatial variation. The effects of these changes are potential to reach the agricultural, energy and industrial sectors, the quality of life and health of populations and the economy at the regional level. The implementation of climate mitigation and adaptation measures is challenging for populations with poor economies, such as those in Northern Minas.
