Collaborative work through CSSP Brazil has investigated the link between some recent flooding events and climate change. For individual events, attribution studies can inform us about how human-induced climate change has altered the likeliness of the event occurring.Įxtreme rainfall, or lack thereof, is the dominant climate hazard in Brazil, with flooding, drought and landslides linked to around 70% of weather-related disasters. The frequency and intensity of weather and climate extreme events across the globe is already changing, with many regions seeing greater impacts compared to pre-industrial times. Rainfall How are extreme events changing? Recent research has been collated in a special issue of the Royal Meteorological Society’s Climate Resilience and Sustainability journal. Knowledge gained through this research is already advancing forecasting capability for extreme events, which may help to further develop disaster management plans and reduce impacts. The CSSP Brazilproject, supported by the UK Government’s Newton Fund, is continuing to develop the science required to build and improve essential climate services in Brazil. In Brazil, the diverse nature of the climate means multiple hazards pose a threat to public health, agriculture, infrastructure and the economy. Developing forecasting systems that can provide warnings early enough is crucial for guiding disaster management strategies.
BEAUTIFUL WEATHER AND NO PLANS DRIVERS
However, in many regions these systems are yet to be fully developed and further research is required to understand the drivers of extreme events, how they are changing with increasing emissions and how well they can be forecast. According to the World Meteorological Organization, half of these events have been caused by weather and climate hazards, which have cost over US$ 3.64 trillion in losses between 19.ĭespite the increase in extreme events, the number of deaths has decreased thanks to proactive disaster management enabled by early warning systems. Globally, extreme weather and climate events have become five times more frequent over the last 50 years. New research through the Climate Science for Service Partnership Brazil project is developing our understanding of extreme events and advancing forecasting capability.
