Modelling the heat mitigation effects of blue roofs and green roofs to assess climate change adaptation potentials in dense urban environments

Urban areas often show higher temperatures than their surrounding rural areas, especially during heat events. This phenomenon is called the Urban Heat Island (UHI) effect. The magnitude of the UHI effect is expressed by the absolute temperature difference between the rural and the urban area and can reach more than 10 °C. During past decades, the magnitude of the UHI effect has intensified in many ...[Read More]

To understand Earth’s changing climate, scientists often examine how the climate has varied in the past, by studying geological records. These records allow us to reconstruct past climates and help us predict planet’s responses to different climate forcings. In this context, it has long been thought that past ice ages on Earth were relatively dry, whereas the warm periods between ice ages we ...[Read More]

The Walker Circulation: what is it and why does it matter

What is the Walker Circulation? The El Niño Southern Oscillation, or ‘ENSO’, is one of the major causes of year to year variability in Earth’s climate. ENSO is characterised by: changes in the temperature of the ocean’s surface in the tropical Pacific Ocean, and by changes in atmospheric circulation in an east-west direction above the Pacific Ocean.   Number two in that list is what makes ENS ...[Read More]
