  • By 2070, 3.5 billion folks might be closely affected by warmth, 1.6 billion of whom will stay in city areas.
  • Rising temperatures can negatively impression weak folks, employees, infrastructure and even GDP, however nature-based options deployed by some cities present another future.
  • Adrienne Arsht-Rockefeller Foundation Resilience Center and the World Economic Forum’s Global Commission on BiodiverCities by 2030 have produced the Heat Action Platform to offer cities all over the world with a roadmap and instruments to handle excessive warmth.

In 2021, summer time within the northern hemisphere noticed a record-breaking heatwave in North America and devastating wildfires in Europe that destroyed properties and important infrastructure. As the world’s temperature continues to rise, heatwaves have gotten extra frequent and longer in length, and their impression extra catastrophic.

By 2070, 3.5 billion folks might be closely affected by warmth, 1.6 billion of whom will stay in city areas. A examine carried out in 9 international locations means that 356,000 deaths have been linked to excessive warmth in 2019 alone. Extreme warmth causes extra deaths than all different climate-driven hazards mixed and has come to be referred to as the “silent killer” since it’s not as visually surprising as floods, forest fires or hurricanes.

Heat creates a cascade of detrimental financial and social results. The financial prices of utmost warmth are already vital and up to date evaluation means that annual financial losses within the US have already mounted to $100 billion because of reductions in labour productiveness. The International Labour Organization tasks that warmth stress will scale back the world’s GDP by $2.4 trillion in 2030. Globally, the results of warmth will strip roughly 1.5 to 2% of annual GDP from native economies.

The social impression can be evident. As the mercury rises, youngsters can’t focus at school, pregnant girls are at larger danger of miscarriage and the aged and folks with a wide range of present well being situations are liable to develop heatstroke owing to their decreased capability to adapt to adjustments in physique temperature. When thermometers hit 100℉ (37.78°C), the chance of accidents will increase by 15% for manufacturing plant and warehouse employees. Heat disproportionately impacts essentially the most weak folks and this downside is exacerbated in densely populated city areas.

In the sunshine of this problem, cities from all over the world are exhibiting extraordinary management, dedication and modern approaches to tackling excessive warmth, demonstrating that there are cost-effective actionable options that may be applied. Through tailored technical help supplied by the Adrienne Arsht-Rockefeller Foundation Resilience Center (Arsht-Rock):

  • Miami-Dade County within the US has established an annual “heat season” as a technique to lift consciousness of the menace that excessive warmth poses;
  • Athens, Greece, is restoring a 1500-year-old Roman aqueduct for native irrigation, which can make the areas by which it passes inexperienced and scale back surrounding temperatures;
  • Seville, Spain, is creating the world’s first heatwave naming and categorization system primarily based on forecasted well being impacts;
  • Freetown, Sierra Leone, is implementing nature-based options by its “Freetown the Tree Town” initiative to plant 1 million timber as a sensible step for cooling town.

Heat-related casualties are preventable and nature-based options can play a significant function in addressing the dangers. Blue and inexperienced infrastructure and corridors present cost-effective options to scale back the impression of heatwaves and the city warmth island impact (the place city or metropolitan areas have a considerably larger temperature than their environment), whereas on the identical time growing the extent of city biodiversity.

Acknowledging the significance of preserving and restoring cities’ pure ecosystems, the WEF’s Global Commission on BiodiverCities by 2030 was created final yr to mix the most recent analysis with sensible options within the service of sustainable, inclusive, and nature-positive city improvement.

Heat is a rising international problem for communities massive and small, throughout each improvement context, and requires collaboration amongst a big selection of disciplines and matter areas. Having an simply accessible, actionable information for mayors and different stakeholders on implement options to strengthen resilience to rising temperatures is crucial.

In response, Arsht-Rock and the Forum’s Global Commission on BiodiverCities by 2030 have joined forces to combine nature-based options into metropolis planning by warmth resilience-building actions. The end result of this collaboration is materialized within the Heat Action Platform (HAP), a one-stop, user-friendly on-line useful resource that gives cities all over the world with a roadmap and instruments to handle excessive warmth. The HAP highlights how the correlation between warmth and biodiversity loss ​​requires holistic insurance policies and modern on-the-ground motion.

The HAP is being developed in partnership with the UN Environment Programme, the Cool Coalition, Rocky Mountain Institute, Global Covenant of Mayors for Climate and Energy, Clean Cooling Collaborative and Mission Innovation. It permits policy-makers and practitioners to grasp warmth dangers and impacts, assess vulnerabilities and determine essentially the most applicable insurance policies and actions to handle the dangers related to warmth.

The HAP is greater than a toolkit; it’s a means for practitioners and others to attach and associate with international consultants to collectively develop options that may work at a neighborhood stage. By offering fastidiously curated sources, interactive analytic instruments, and templates from a number of establishments that may be tailored and utilized in totally different contexts, cities can have an array of choices to fill present gaps in present choices.

The HAP goals to change into a significant car to construct warmth resilience by elevating consciousness about heat-related dangers in cities, educating decision-makers, and offering them with actionable options whereas highlighting the connection between fostering city biodiversity and cooling down cities. Mayors’ and metropolis officers’ precedence is to guard folks’s lives. Taking modern, efficient and data-driven motion to handle excessive warmth will safeguard residents from the preventable “silent killer” and paves the way in which for a extra sustainable, resilient and affluent future in cities.
