Extreme heat is rapidly becoming one of the deadliest and most overlooked impacts of climate change. Yet it is not only an environmental challenge - it is a public health crisis, a gender equality issue and a climate justice issue. Women, girls, trans, intersex and non-binary people often experience disproportionate impacts from extreme heat, not because of individual characteristics, but because of structural inequalities that shape exposure, access to resources, decision-making power and adaptive capacity. Heat affects maternal and reproductive health, mental health, livelihoods, food and water security, unpaid care work, labour conditions and gender-based violence. These impacts are further intensified by poverty, discrimination, extractive industries and unequal access to land, water, cooling, healthcare and finance. Despite growing global attention to heat, adaptation responses remain largely technocratic or focused on individual behavioural change. Far less attention is given to the community organisations already developing collective, locally led solutions that address the structural drivers of vulnerability. Join the Global Alliance for Green and Gender Action (GAGGA), with support from ClimateWorks Foundation, to hear emerging findings from one of the first cross-regional Feminist Participatory Action Research initiatives on extreme heat. Led by women-led community-based organisations across Africa, Asia and Latin America, the research documents how communities are experiencing extreme heat, the adaptation strategies they are already implementing, and what is needed to scale these solutions through more equitable climate finance. The session will bring together funders, researchers, practitioners and women-led organisations working at the intersection of climate, health and gender. Using the research as a provocation for conversation, participants will explore what these findings mean for how we think, act and fund. Rather than framing communities as vulnerable populations, the discussion will highlight women-led and Indigenous-led community organisations as innovators and leaders of adaptation, generating practical adaptation strategies, Indigenous knowledge and policy solutions that deserve greater recognition and investment. The conversation will also explore what a different model of climate finance could look like - one that invests directly in trusted local organisations, values feminist and Indigenous knowledge, and shifts decision-making closer to communities.
