A Nature study projects climate change will cause an additional 123 million malaria cases and 532,000 deaths in Africa by 2050, even if current emissions pledges are met. Strikingly, only a tiny net increase in transmission (0.12%) comes from ecological changes in mosquito range; 79% of extra transmission risk and 93% of additional deaths stem from “disruptive” extremes—floods and cyclones that destroy housing, roads, clinics, and supply chains. As storms and floods intensify, 67% of Africans will see rising malaria risk, mostly in regions already endemic rather than new frontiers. The authors argue that malaria research has underweighted system fragility: climate-resilient health and supply chains, integration of malaria control into disaster planning, and pre-positioning drugs and community health workers before extreme weather will determine whether eradication remains feasible in the first half of this century.

World Weather Attribution scientists found that this January’s catastrophic floods across South Africa, Mozambique, and Zimbabwe—delivering roughly a year’s rain in 10 days and affecting 1.3 million people—were made substantially more intense by anthropogenic climate change. The event, enhanced by La Niña’s wetter conditions, saw rainfall so extreme that some areas got a full rainy season’s total in two to three days, sweeping away roads and bridges, and destroying clinics. Researchers conclude a ~40% increase in intensity is impossible to explain without human-induced warming. The episode exposes how African countries that contribute just 3–4% of global emissions bear disproportionate loss and damage, and highlights the need for Africa-developed climate models tailored to local dynamics to guide infrastructure and early-warning investment.

An EEA–Eurofound survey of 27,000 people across 27 EU countries finds 80% of Europeans have already experienced climate-related impacts—heat, flooding, wildfires, water scarcity, storms, or vector-borne disease—in the last five years, with more than half very or quite concerned about future extreme heat and wildfires. Yet one in five households lacks any listed protective measures (shading, floodproofing, extreme-weather insurance), and 38% say they cannot afford to keep their homes adequately cool in summer. Lower-income respondents report disproportionate problems, including four times more frequent issues accessing safe water. Awareness of local authority adaptation measures is patchy, and northern Europe—despite fewer reported impacts—also shows low uptake of household resilience measures. The report underscores that EU prosperity under a rapidly changing climate will depend on scaling affordable household-level adaptation alongside public infrastructure.

Researchers unveiled a new dynamical model that predicts September Arctic sea-ice extent one to four months ahead with accuracy surpassing existing methods. Using daily ice-extent data back to 1978, the approach decomposes Arctic sea ice into interacting ‘rhythms’ driven by long-term climate memory, regular seasonal cycles, and fast weather fluctuations. Tested in real time for September 2024 and retrospectively for prior years, the model captured subseasonal-to-seasonal changes and regional contrasts effectively. Accurate summer ice forecasts are critical for Indigenous hunters, shipping, offshore industry, and risk management in a rapidly warming Arctic. The model includes atmospheric and oceanic variables—air temperature, sea-level pressure—to better resolve rapid swings, potentially improving forecasts of both ice conditions and linked mid-latitude weather anomalies.

Lehigh University’s Center for Catastrophe Modeling and Resilience warns that climate change is pushing US private insurance toward a breaking point, as traditional tools—premium hikes, peril pooling, catastrophe bonds—fail and insurers withdraw from high-risk markets. The authors propose resilience bonds issued via public–private partnerships: insurers quantify risk reduction from physical resilience measures, enabling governments to float bonds whose proceeds finance upgrades. But where risk cannot be reduced enough to pass benefit–cost tests, the research proposes a coherent, well-funded national managed-retreat framework, informed by social science on ‘ecomyopia’ (identity-driven denial of relocation needs) and the limits of indices like the Social Vulnerability Index. Disaster models must move beyond physical loss estimates to incorporate culture, history, and structural inequality in deciding where to invest in resilience versus where to help people move.
