<ul class="summary-list"><li>At least 62 people have been killed in the worst flooding to hit Spain in decades.</li><li>Flash floods are becoming more common and more intense due to global warming.</li></ul>At least 62 people have been killed and many more are missing in the <a target="_blank" class="" href="https://www.businessinsider.com/spain-flooding-51-dead-in-valencia-region-economic-hub-2024-10">worst flooding to hit Spain in decades</a>.Torrential rain hit parts of the country on Tuesday, cutting off main roads, delaying flights, and damaging homes.The rain was the result of a weather phenomenon known as a cold drop, in which cold air moves over warm water.The warm air then rises rapidly, leading to the formation of huge cumulonimbus clouds capable of releasing violent downpours that can devastate towns and cities.Such extreme weather events have a huge human and economic cost — and scientists believe global warming, combined with the way humans have developed the natural landscape, will only make the problem worse.<h2 id="971184fb-8d33-48d1-979d-6445b6e539be">The cost of extreme weather</h2>Estimates for the economic costs of extreme weather and flooding vary, but many tend to agree that they are on the rise.According to the European Environment Agency, extreme weather in Europe caused economic losses of assets estimated at more than $800 billion between 1980 and 2023.Last year, a study by <a target="_blank" class="" href="https://www.theguardian.com/environment/2023/oct/09/climate-crisis-cost-extreme-weather-damage-study">Victoria University of Wellington in New Zealand</a> said the damage caused by the climate crisis through extreme weather has cost $16 million an hour for the past 20 years.<a target="_blank" class="" href="https://www.weforum.org/agenda/2023/01/extreme-weather-economic-cost-wef23/">The World Economic Forum</a> calculated that the cost of extreme events had increased nearly eight times globally, inflation-adjusted, since the 1970s.The impact of flash flooding can be particularly severe because, often, there is very little warning.<h2 id="8409be50-c212-466d-bbd2-62c416ac5204">Flash flooding in dry areas</h2>Flash floods are <a target="_blank" class="" href="https://www.businessinsider.com/what-is-flash-flood-warning-how-to-stay-safe-vermont-2023-7">different from regular flooding</a> because they develop quickly, in the span of a few hours or even minutes.They can be far more devastating in dry areas because parched soil tends to repel water rather than allow it to soak in.That means surges can result from as little as 10 millimeters in just one hour, according to a<a target="_blank" rel="noopener noreferrer" class="c-link" href="https://affiliate.insider.com?h=3735d139977ac068c02d638e81b04695e0ab6b1d06970add3b44fafb88d52e11&amp;postID=6722014ce5b5408300715e9a&amp;postSlug=flash-floods-spain-increasing-globally-experts-infrastructure-change-2024-10&amp;site=bi&amp;u=https%3A%2F%2Fwww.nature.com%2Farticles%2Fd41586-023-00626-9.epdf%3Fno_publisher_access%3D1%26r3_referer%3Dnature"> 2023 article in Nature</a>."Our analysis using the Emergency Events Database shows that, since 2000, such regions experienced less than half (47%) of deadly flash floods globally, yet saw almost three-quarters (74%) of related deaths," the authors wrote.The same researchers found that the rate of dryland flash flooding around the world was 20 times higher between 2000 and 2022 than it was between 1900 and 1999.Ernesto Rodríguez Camino, a senior state meteorologist and member of the Spanish Meteorological Association, said flash flooding is becoming more frequent, a trend which is set to continue because of the damaging effects of global warming."Events of this type, which used to occur many decades apart, are now becoming more frequent, and their destructive capacity is greater," he said.<h2 id="c6269754-7554-446d-a63e-b8d93fdbfdc3">Why are there more flash floods?</h2>The Environmental Defense Fund (EDF), a US-based nonprofit, <a target="_blank" class="" href="https://www.edf.org/why-are-floods-hitting-more-places-and-people">said</a> flash flooding has intensified because of increased rainfall and heat waves.The rise in the world's average surface temperature — which was more than 2 Degrees Fahrenheit warmer in 2020 than it was 100 years ago — has resulted in more moisture and clouds in the air, the organization said.According to the EDF, modern infrastructure, including buildings, roads, and sidewalks, has eliminated natural landscape features that would have slowed flooding in the past.It added that stormwater systems designed to protect buildings are often too old and not vast enough to handle the increasing amount of major weather events caused by global warming.Additionally, houses are continuing to be built in areas that are prone to flooding, the organization said.The <a target="_blank" class="" href="https://www.who.int/health-topics/floods#tab=tab_1">World Health Organization</a> (WHO) said people who live on floodplains or in buildings without flood protections or warning systems are most vulnerable.<h2 id="283c598d-eb50-4251-afb8-e7fbf0cb4832">What can be done?</h2><div type="image" title="Emergency workers clear debris the morning after heavy rains and flash floods hit the area on October 30, 2024 in Letur, Albacete province, Spain" height="3333" width="5000" msid="114787520" hostid="261" sizebytes="2262486"></div>Non-environmental factors, such as new infrastructure and better weather warnings, can help prevent the impact of flash flooding.Jess Neumann, an associate professor of Hydrology at the University of Reading, said that a long-term solution would involve the "radical redesign of urban areas.""Flash floods can affect anyone, anywhere. We take preparation for other hazards such as earthquakes and tsunamis very seriously with education, drills, and emergency kits," she said. "It is time we afforded the same to flood risk preparedness."John Marsham, a professor of atmospheric science at the University of Leeds, agrees with Neumann's assessment."Our entire infrastructure and civilization are based around a climate that no longer exists," he said, adding that some locations are becoming more difficult to insure against flood damage.Some cities are already considering better precautions for extreme weather events. For example, in 2022, the US Army Corps of Engineers unveiled its proposal to build a <a target="_blank" class="" href="https://www.nytimes.com/2022/09/26/nyregion/storm-project-new-york-harbor-flooding.html">$52 billion moveable sea barrier</a> along the New York Harbor to protect against storm surges.These protections would also allow local economies to recover faster.The EDF reported that the average flood event from excessive rainfall in the US costs around $4.7 billion.Marsham and Liz Stephens, a professor in climate risks and resilience, said that local governments should also implement stronger warnings about the risks of flash flooding to prevent death and injuries."People shouldn't be dying from these kinds of forecasted weather events in countries where they have the resources to do better," Stephens said.

Flash floods are a worsening scourge worldwide — here's why

The report also noted that the inflation outlook in India remains a critical focus for the <keyword id="19899810" type="General" weightage="20" keywordseo="reserve-bank-of-india" source="keywords">Reserve Bank of India</keyword> (RBI). Recent data indicates that the <keyword id="19999655" type="General" weightage="20" keywordseo="Consumer-Price-Index" source="keywords">Consumer Price Index</keyword> (CPI) inflation rose to 5.08 per cent in June 2024, driven primarily by higher food and beverage prices. "CPI inflation is expected to remain below or close to 5.0 per cent in the remaining months, except for Sep'24 and Oct'24" said the report. The report also added that the monsoon season plays an important role in shaping food prices, and while the current monsoon has shown a satisfactory surplus, excess rainfall could lead to crop losses, adversely affecting food inflation. The RBI's ability to manage inflation expectations is crucial, especially as it navigates the delicate balance between supporting <keyword id="19900794" type="General" weightage="20" keywordseo="economic-growth" source="keywords">economic growth</keyword> and maintaining <keyword id="19960158" type="General" weightage="20" keywordseo="price-stability" source="keywords">price stability</keyword>. "With monsoon progressing satisfactorily with 2 per cent surplus till date and progress of area coverage under Kharif crops showing 2.9 per cent yoy, we expect inflation to remain within RBI target in FY25. However, with La Nina getting precedence, excess rainfalls could result in crop loss and thus a negative impact on food prices" the report added. In response to the evolving economic landscape, the report mentioned that the RBI is likely to continue its stance of withdrawing accommodation. This approach aims to address inflationary pressures while ensuring that the economy remains on a growth trajectory. However, the central bank faces challenges in policy transmission, as deposit rates have shown downward rigidity despite a declining weighted average lending rate (WALR). This situation complicates the RBI's efforts to implement effective monetary policy. "Even though the Banks are chasing deposits to fund the incremental credit growth, RBI recent report suggests, the weighted average lending rate (WALR) on fresh rupee loan decreased by 11 bps from the beginning of the year (i.e. from 9.43 in January'24 to 9.32 in June'24)" the report noted. Looking ahead, the RBI's decisions will be influenced by both domestic and global economic conditions. The potential for a recession in the US and geopolitical tensions could impact inflation dynamics in India. As such, the RBI's monetary policy will need to remain flexible and responsive to these external factors while striving to achieve its inflation targets and support sustainable economic growth.
