4 de sept. de 2019 · During summer months, relatively large SUHI intensity is associated with increased local warming and extreme heat events in urban areas 13,36,37.
27 de dic. de 2023 · Global warming has resulted in higher frequencies of climate extremes, such as drought periods or heat waves. Heat waves are intensified in urban areas due to the urban heat island...
Extreme heat exposure is highly unequal and severely impacts the urban poor. While previous studies have quantified global exposure to extreme heat, the lack of a globally accurate, fine-resolution temporal analysis of urban exposure crucially limits our ability to deploy adaptations.
The research shows that exposure to extreme heat in urban areas is much more widespread—and increasing in many more areas—than previously realized. The results of this can affect all aspects of life, from food security, water accessibility and overall public health.
25 de oct. de 2021 · This phenomenon is known as the urban health island effect. 11 For example, while the average air temperature in the centre of a large city like London, can be 4°C higher than outer rural areas, this differential can reach 10°C during extreme heat events, with the largest differential at night. 12 13 Urban heat islands are caused by use of mater...
29 de nov. de 2023 · The IPCC says extreme heat in urban areas will increase levels of mortality and heat-related illnesses, especially among the elderly and young children; impair concentration and cognition, affecting learning and educational outcomes for children, particularly in South Asia and Africa; and reduce labor capacity during hot periods by 20% or more b...
13 de feb. de 2024 · Urban greening has been linked to mitigation of heat islands (i.e., temperature reduction), improved air and water quality, reduction of stormwater run-off, biodiversity benefits, and enhanced...
