Evidence of climatic health hazards on the general population has been discussed in many studies but limited focus is placed on developing a relationship between climate and its effects on occupational health. Long working hours with high physical activity can cause health problems for workers ranging from mild heat cramps to severe heat stroke leading to death. The paper presents the possible risk of heat hazard to outdoor workers, using the example of Warsaw. The heat stress hazard, defined by WBGT values above 26 and 28°C and UTCI above 32 and 38°C, is assessed from two perspectives: its spatial distribution on a local scale and its temporal changes during the 21st century due to climate change. City centre and industrial districts were identified as the places with the greatest heat stress hazard. The number of heat stress days in a year (as predicted for the 21st century) is increasing, meaning that heat-related illnesses are more likely to have a direct impact on workers’ health.
The health of individuals and societies depends on different factors including atmospheric conditions which influence humans in direct and indirect ways. The paper presents regional variability of some climate related diseases (CRD) in Poland: salmonellosis intoxications, Lyme boreliosis, skin cancers (morbidity and mortality), influenza, overcooling deaths, as well as respiratory and circulatory mortality. The research consisted of two stages: 1) statistical modelling basing on past data and 2) projections of CRD for three SRES scenarios of climate change (A1B, A2, B1) to the year 2100. Several simple and multiply regression models were found for the relationships between climate variables and CRD. The models were applied to project future levels of CRD. At the end of 21st century we must expect increase in: circulatory mortality, Lyme boreliosis infections and skin cancer morbidity and mortality. There is also projected decrease in: respiratory mortality, overcooling deaths and influenza infections.
Na przestrzeni ostatnich dziesięcioleci obserwuje się burzliwy rozwój miast. W wielu miastach Polski, w tym także w Warszawie, proces ten odbywa się w warunkach braku miejscowych planów zagospodarowania przestrzennego. Przy podejmowaniu decyzji lokalizacyjnych i wydawaniu pozwoleń na budowę władze lokalnych jednostek administracyjnych kierują się ogólnymi wskazaniami rozwoju miasta zawartymi w studium uwarunkowań i kierunków zagospodarowania przestrzennego. Celem obecnego doniesienia jest przedstawienie, w jakim stopniu projektowane kierunki rozwoju przestrzennego Warszawy mogą wpłynąć na niektóre cechy klimatu miasta, ważne dla jakości życia mieszkańców. Szczególna uwaga zostanie zwrócona na tzw. miejską wyspę ciepła.

The last decades have brought intensive development of urban areas. In many Polish cities, including Warsaw, such development takes place without obligatory local plans. Thus, administrative permission decisions concerning any investment are prepared on the basis of so-called studies of conditions and directions of spatial planning. The aim of the present paper is to discuss how general plans of spatial development in Warsaw can influence some features of its climate which are important for the quality of life of Warsaw citizens. Special attention is paid to Urban Heat Island.
