The Environment Agency's latest assessment reveals that 6.3 million properties in England are now at risk of flooding from rivers, the sea, or surface water—a significant increase from previous estimates. This rise is primarily attributed to enhanced data accuracy and modelling techniques. Projections indicate that, due to climate change, this number could escalate to 8 million by mid-century, potentially placing one in four properties in flood-prone areas. The assessment also highlights an increased risk of coastal erosion, with 3,500 properties expected to be affected by 2055, rising to about 10,100 by 2100. These findings underscore the pressing need for comprehensive flood defence strategies and resilient infrastructure to safeguard communities against evolving environmental threats. #climatechange https://lnkd.in/eY9yKRP7

As climate change intensifies, homeowners across the United States are facing a growing insurance crisis. Since 2018, insurers have nonrenewed more than 1.9 million home insurance contracts nationwide, with over 200 counties experiencing a tripling or more in non-renewal rates. This trend is particularly pronounced in states like California and Florida, where increased risks from wildfires and hurricanes have led major insurers to reduce or cease coverage. For instance, in California, some companies have stopped accepting new home insurance applications in high-risk areas. The implications are significant: obtaining a mortgage becomes challenging without insurance, potentially leading to declining property values and reduced tax revenues for essential community services. This situation underscores the urgent need for comprehensive strategies to address the escalating risks posed by climate change. #climatechange Hydroinformatics Solutions https://lnkd.in/d3RQZrBi

The US National Oceanic and Atmospheric Administration (NOAA) is rethinking its approach to modelling critical Pacific Ocean cycles, such as El Niño and La Niña, as record-high sea temperatures globally disrupt traditional weather patterns. Historically relied-upon techniques for predicting these natural phenomena, which influence global weather and climate over years-long cycles, are now being challenged by the impacts of climate change. Rising ocean temperatures are altering the behavior of these cycles, making them less predictable and reducing the accuracy of forecasts. This uncertainty is causing ripple effects, from disruptions to farming and trade to increased vulnerability for disaster planning. The challenges highlight the need for more sophisticated prediction tools that account for the warming of tropical oceans and evolving global climate patterns. As climate change continues to intensify, forecasters and scientists worldwide are urging a shift towards more adaptive modeling systems to ensure preparedness for extreme weather and its far-reaching consequences. https://lnkd.in/ecwzVmeg #climatechange

Climate change is increasing the frequency and severity of urban floods, highlighting the urgent need for resilient water infrastructure. Many cities are struggling with inadequate systems, resulting in significant losses during extreme weather events. To address these challenges, urban areas must adopt sustainable water management strategies, such as nature-based solutions and robust infrastructure investments. These proactive measures are critical for protecting communities, reducing economic losses, and enhancing resilience against climate-related risks. https://lnkd.in/eKQG9f4p

 Five under-the-radar weather and climate issues to watch in 2025: - Urban Heat Islands Intensifying: Cities are experiencing increased temperatures due to concrete and asphalt absorbing heat, exacerbating health risks and energy consumption. - Shifting Agricultural Zones: Climate change alters traditional farming regions, impacting crop yields and food security. - Increased Atmospheric Moisture: Warmer air holds more moisture, leading to heavier rainfall and flooding events. - Permafrost Thawing: Melting permafrost releases greenhouse gases, accelerating climate change and affecting infrastructure in cold regions. - Changing Jet Stream Patterns: Alterations in the jet stream influence weather extremes, including prolonged heatwaves and cold spells. https://lnkd.in/dvgE8dHX #climatechange Hydroinformatics Institute These emerging challenges underscore the need for proactive adaptation and mitigation strategies in the coming year.

In October 2024, Spain's Valencia region faced unprecedented flooding, with torrential rains causing widespread devastation. Over 200 lives were lost, and infrastructure, homes, and farmlands were heavily damaged. The floods also impacted the Albufera Natural Park, one of Europe’s most critical wetlands, leaving it contaminated with debris, pollutants, and agricultural runoff, threatening local biodiversity. This disaster highlights the growing challenges posed by climate change as extreme weather events become more frequent and severe. Experts emphasise the need for enhanced climate resilience strategies, including improved urban planning, wetland restoration, and advanced flood management systems. Europe must prioritise investments in sustainable infrastructure and cross-border collaboration to mitigate future risks. https://lnkd.in/d_7wMgkx #climatechange

A United Nations report reveals that over 75% of Earth's land experienced increased aridity between 1970 and 2020, posing significant threats to ecosystems and human livelihoods. The report attributes this trend to human-induced climate change, deforestation, and water mismanagement. Projections indicate that if current warming trends persist, nearly 5 billion people could face severe water scarcity by the end of the century, jeopardising agriculture and food security. The summit emphasises the necessity for sustainable water management and international cooperation to combat desertification and its associated challenges. #climatechange https://lnkd.in/ddgNJsxm

Natural catastrophes like floods and hurricanes have pushed global insurance losses beyond $135 billion in 2024, marking the fifth consecutive year of losses exceeding $100 billion. Key findings reveal: - Flooding Impacts: Europe saw its second-highest flood-related insured losses, with $10 billion attributed to intense flooding in Spain and other regions. Globally, it was the third-costliest year for flooding. - Hurricanes in the US: Two hurricanes caused significant devastation in Florida, with the US bearing two-thirds of total global losses. - Climate risks: 2024 is set to be the hottest year on record, with a 1.54°C rise above pre-industrial levels. Rapid intensification of storms and extreme rainfall are increasingly linked to climate change. Investing in climate resilience is no longer optional—it’s a necessity. https://lnkd.in/evtNAB23 #climatechange #climateadaptation Hydroinformatics Institute

Climate change is intensifying threats to water resources globally, leading to more frequent and severe droughts and floods. The extreme events compromise water quality and availability, impacting ecosystems, human health, and economic activities. Sustainable water management practices, including pollution reduction and efficient water use, are needed to enhance resilience against climate-related challenges. https://lnkd.in/gHhrnuRk

Recent catastrophic floods across Europe, notably in Spain's Valencia region, have caused extensive damage and loss of life. While climate change is a significant factor, the degradation of natural ecosystems due to urban expansion and industrial agriculture has also played a crucial role. The destruction of forests and wetlands disrupts local water cycles, intensifying extreme weather events. Addressing these challenges requires a holistic approach integrating climate action with ecosystem restoration to enhance regional resilience. https://lnkd.in/dXHbjvhT #climatechange Hydroinformatics Institute
