G20 Radio Bulletin 103 - Study Finds Human Activity Heightens Rainfall Intensity by 15%
According to a study conducted by ClimaMeter, the increased intensity of rainfall in Rio Grande do Sul over the past few decades is due to the climate crisis, which has been further aggravated by human activities. Consequently, the Brazilian state is facing significant challenges with floods affecting its population. The climatologist underscores the crucial role of the G20 in formulating objectives and tackling worldwide climate issues. Listen to the report to learn more.
Reporter: In an exclusive interview with the G20 website, Climatologist Francisco Eliseu Aquino, who leads the Department of Geography at the Federal University of Rio Grande do Sul (UFRGS), asserted that the recent tragedy in Southern Brasil has been exacerbated by the climate crisis. Aquino supported his claim with data from a climate study conducted by researchers at ClimaMeter, a climate and environmental sciences laboratory affiliated with the University Paris-Saclay in France.
As per the findings of researchers, an examination of meteorological data covering the past four decades indicates that human activities have led to a 15% increase in the intensity of rainfall compared to its inherent capacity. Global warming is pinpointed as the principal driver behind this escalation.
Francisco Aquino: The comprehensive integration of climate change considerations into daily agendas remains an elusive objective. This challenge is not unique to any specific region but is pervasive globally. However, within Brasil, there exists a pressing necessity to bolster research centers and universities. This endeavor is essential for the advancement of rigorous science, technology, and environmental education initiatives. Such efforts aim to enhance public awareness of risk areas and foster a more acute perception of environmental hazards among citizens.
Reporter: Aquino underscores the pivotal role of the Amazon rainforest in regulating South America's hydrological system, emphasizing the imperative for environmental preservation.
Francisco Aquino: The geographical landscape of South America, notably Brasil, underscores the pivotal role of the Amazon rainforest as the principal source of moisture and the primary natural regulator of the hydrological system. The ongoing heatwave, directly linked to climate change, poses significant obstacles by impeding the passage of tropical cyclones and cold fronts. This heatwave-induced blocking effect intensifies the transport of moisture from the Amazon, thereby exacerbating storm activity.
Reporter: The climatologist proposed that countries assume responsibilities and promptly undertake actions to facilitate effective global agreements. He asserts that the G20 plays a crucial role in this endeavor.
Francisco Aquino: A global agreement spearheaded by the G20 presents a unique opportunity to expedite resilience-building efforts and mitigate the impacts of climate change.
Reporter: Rio Grande do Sul is currently grappling with one of its most severe crises due to floods, prompting the Federal Government to take swift action. A series of emergency measures and substantial investments have been implemented to alleviate damages and aid the affected population. Following the enactment of Provisional Presidential Decree 1,218/24, President Luiz Inácio Lula da Silva has authorized the disbursement of BRL 12.1 billion ($2.35 billion) in extraordinary credits for the state. This brings the total resources released during this initial relief phase to over BRL 62 billion ($12 billion).
