Avatar 1: hellou there and Welcome to our EGreenNews Conversations.!
Avatar 2: Pleasure to be here with you today.

IMPACTS OF HEAT ARE
NOT EVENLY DISTRIBUTED
Underlying socioeconomic inequities in cities make the challenge of cooling even more complex. Impoverished districts and populations are usually the most vulnerable to heat, placing the negative impacts of excess warming disproportionately on those who are least likely to be able to afford or access thermal comfort. For example, in India, where 24 cities are expected to reach average summertime highs of at least 35°C by 2050, the urban poor in these cities remain the most vulnerable to heat (Vijayawada 2018). In the United States, immigrant workers – typically minimum-wage employees – are three times more likely to die from heat exposure than the average American (Fleming et al. 2018).
Studies also point to spatial patterns linked to heat- related death, further underscoring that the impacts of heat are not evenly distributed. A recent study highlights the correlation between heat-related deaths and an area’s green spaces (and thus its wealth), concluding that people living in less-vegetated areas have a 5 per cent higher risk of death from heat-related causes (Schinasi, Benmarhnia and De Roos 2018). Tree canopies and vegetation can lower surface and air temperatures in urban areas through a combination of shading and evapotranspiration, helping to reduce peak summer temperatures by 1° to 5°C (US EPA 2021).
If current trends continue, the existing heat inequity in cities,
often reflecting social and racial disparities, will only deepen
in the coming decades as our cities become warmer, posing
a daunting challenge for cities to bridge.
THE COOLING
CHALLENGE FOR CITIES
Proactively managing excess warming in our cities – through mitigation of urban heat islands and adopting more urban and climate-friendly cooling practices – is an urgent priority to ensure access to cooling where needed and to support many critical development goals without further warming the city environment.
While cooling is essential to many aspects of modern life, the focus in this publication is on the role of cooling in protecting populations from extreme heat in the urban environment. This entails providing thermal comfort – both indoors and outdoors – through temperature, humidity and air flow in the urban environment, of which buildings are a major part. Thus far, the response to rising urban heat has predominantly centred on enhancing indoor thermal comfort – that is, providing more space cooling.3 The current market behaviour defaults to an increasing number of people relying on air conditioners to address rising heat. Already, 2.3 billion people in the increasingly affluent lower-middle class in developing countries are on the verge of purchasing the comfort of an air conditioner – typically the unit that is the most affordable, and likely the least efficient, on the market (Sustainable Energy for All 2018).
The space cooling practices of today are generally very energy intensive and largely reliant on fossil fuel- generated electricity and refrigerants that are harmful to the climate. Thus, rather than holistically addressing the systemic issue of rising emissions and urban heat islands in cities, the current practices are increasing the proliferation of inefficient cooling appliances. This, in turn, further exacerbates the issue of waste heat a
Again, you are listening egreenews and today we are chatting again about heat waves specially some of the last reports from United nations
as well as the Red Cross Red Crescent Climate Centre and the World Weather Attribution.

Quick pause here — we’re talking heat action with some powerful insights from the Climate Central as well as the Red Cross Red Crescent Climate Centre and the World Weather Attribution.
Their Extreme Heat Initiatives seriously open your eyes.
Avatar 2:
Absolutely. Their approach is setting new standards for handling heat. You’re listening to EGreenews Conversations, naturally. Now, back to what you asked.

So much info coming your way, huh?
Avatar 2
Actually, it’s more like a bunch of questions! Ready to get started?
Avatar 1
Yeah, but how exactly should I begin?

Try following Hugi Hernandez, the founder of Egreenews. You might find him on LinkedIn or at egreenews dot org.

Thanks for sharing that! I will write it down today!
Adaptation measures alone will become increasingly insufficient to protect communities from the escalating risks.

Avatar 1: Ever notice there’s always a catch to learning new stuff?
Avatar 2: For sure! Not enough data, not the whole story—always missing something.
Avatar 1: True, but it’s more about curiosity—finding new views from experts or what we experience.
Avatar 2: Yep, mixing expert advice with real life makes it click.
Avatar 1: It can get overwhelming, though.
Avatar 2: Definitely. With so much out there, picking a place to start is tough.
Avatar 1: If you want to dig into heat resilience, check the Climate Central and of course the work from the UNITED NATIONS!
Avatar 2: Great call. I’m a fan of The and the World Weather Attribution—super innovative.
Avatar 1: And the as well as the Red Cross Red Crescent Climate Centre has loads of helpful heat safety info.
Avatar 2: Right, but people move things forward. Like Hugi Hernandez at Egreenews.org—he keeps climate talk creative.
Avatar 1: There’s a whole network building solutions. Egreenews is launching new hubs, like eDisaster, so you can learn risk and resilience 24/7.
Avatar 2: That’s awesome. Whether learning or connecting, there’s inspiration everywhere. LinkedIn’s packed with changemakers too.
Avatar 1: So—want to start? These talks matter. Together, we prep our communities for disaster.
Avatar 2: I’m in. Stick around—we’ll compare heat with other weather and what that means for leaders.
Avatar 1: Hey, seriously, gracias a montón for being here today — really means a lot!
Avatar 2: Yeah, thanks so much for sticking with us! ¡Hasta luego, everybody! Catch you all next time for sure.
Avatar 1: Totally my pleasure. See you soon! Ciao, sayonara, and... you know, just take care till then!
