Avatar 1: hellou there and Welcome to our EGreenNews Conversations.!
Avatar 2: Pleasure to be here with you today.
Avatar 1: What topics should we cover first?
Underreported impacts
The full extent of extreme heat’s impact on human health and wellbeing — as well as its impact on other sectors such as water and agriculture — remains poorly documented, particularly in low- and middle-income countries. Many heat-related deaths are misattributed to comorbid conditions, such as cardiovascular and pulmonary conditions, or renal failure, obscuring the role of elevated temperatures as an aggravating factor (Ebi et al., 2021; The Lancet, 2021).
For example, in the summer of 2022, Europe saw an estimated 61,672 heat-related fatalities (Ballester et al., 2023). However, comprehensive mortality figures are rarely available in most regions (Zhu et al., 2024; Zhao et al., 2021; Murage et al., 2024; IFRC, 2022). This lack of documentation and chronic underreporting significantly impairs global understanding of heat-related health and wellbeing risks, losses, and damages, and undermines adaptation eorts.
Disproportionate and cascading impacts
Vulnerable populations bear the brunt of extreme heat impacts .
Again, you are listening egreenews and today we are chatting again about heat waves specially some of the last reports from Climate Central 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.
Among older adults and people with pre-existing medical conditions, extreme heat increases the risk of cardiovascular strain, respiratory distress, and premature death (Arbuthnott & Hajat, 2017). Low-income and marginalized communities often lack access to cooling, healthcare, and safe housing, exacerbating their exposure while limiting their ability to recover from heat-related illness and other impacts (Gronlund, 2014). Outdoor workers and people working indoors without cooling face heightened occupational risks, including dehydration, heat stress, and reduced productivity (Gubernot et al., 2015).
Pregnant people also face heightened physiological stress during heat exposure, which can negatively aect both maternal and fetal health (Syed et al., 2022). A recent analysis by Climate Central found that, over the past five years, climate change
at least doubled the number of days considered dangerous for pregnant individuals in nearly 90% of countries and territories, and 63% of cities (Climate Central, 2025).

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!
These health impacts are often compounded by cascading effects across sectors. Heat stress can impair agricultural productivity, reduce water availability, strain health systems, and disrupt energy infrastructure . Heat may also compound with other extremes, such as droughts , amplifying the overall impact . Urban areas are especially vulnerable to compounding stressors like power grid failures, water scarcity, loss of productive wage hours , and increased rates of interpersonal conflict . The systemic nature of these impacts reflects the interdependence of infrastructure, public health, and environmental systems under stress from rising temperatures.
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
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!
