A comprehensive analysis by the International Chamber of Commerce revealed the stark reality of adaptation finance. While private sector funding accounts for over half of global mitigation efforts, it contributes only 8% to adaptation investments. The ICC report identifies three strategic priorities for scaling private adaptation investment: strengthening climate risk data transparency, embedding business participation into National Adaptation Plans, and developing innovative financing instruments like resilience bonds tied to avoided losses. African nations exemplify the challenge, receiving only 6% of adaptation finance from private sources compared to 35% in Asia, where commercial markets are more robust. With extreme weather events already causing $2 trillion in economic losses from 2014 to 2023, the report argues that adaptation represents not philanthropy but essential risk management for any business dependent on stable infrastructure or supply chains.

A landmark World Economic Forum study revealed that climate-driven health risks could cost the global economy at least $1.5 trillion in lost productivity by 2050, with the burden falling heaviest on essential sectors. The food and agriculture sector faces the steepest losses at $740 billion, threatening global food security as extreme heat renders outdoor work increasingly dangerous. The built environment sector confronts $570 billion in productivity losses, while the healthcare sector itself faces $200 billion in reduced capacity even as climate-driven diseases surge in demand. Lower-income households and less-educated workers face disproportionate impacts, as they're more likely to work in climate-exposed sectors and have less access to protective cooling technologies. The report emphasises that early investment in climate health adaptation - from heat-stable medications to cooling technologies for outdoor workers - can unlock innovation opportunities while protecting vulnerable populations.

The World Meteorological Organization (WMO) issued a stark warning about Earth's increasingly erratic water cycle, with two-thirds of global river basins experiencing abnormal conditions - either too much or too little water - for the sixth consecutive year. The report documents extreme swings from record droughts gripping the Amazon Basin and southern Africa to devastating floods across central Africa, Europe, and Asia. All glacier regions worldwide reported ice losses for the third straight year, contributing 1.2mm to global sea level rise and heightening flood risks for hundreds of millions in coastal areas. Scientists describe the water cycle as "increasingly difficult to predict," with climate change enabling the atmosphere to hold more moisture, leading to either extended dry periods or intense rainfall events. The WMO emphasised that understanding and quantifying these hydrological extremes is critical for managing cascading risks to food security, economic stability, and social cohesion.

New research projects that Brazil's risk of mosquito-borne disease will surge significantly by 2080, with Aedes aegypti density (the yellow fever mosquito) potentially increasing 30% nationwide under high-emission scenarios and nearly doubling in southern and southeastern hotspots. Under the lowest emissions scenario, mosquito density would still rise 11% by 2080, but aggressive climate action could cut projected increases by two-thirds - demonstrating the tangible public health benefits of emission reductions. Brazil already carries one of the world's highest burdens of mosquito-borne disease, with dengue, Zika, and chikungunya transmission expected to intensify as warmer temperatures accelerate mosquito development and increase biting activity. The country is pioneering innovative responses, including mass releases of Wolbachia-infected mosquitoes and deployment of home-grown dengue vaccines, representing a comprehensive strategy to combat climate-amplified vector-borne diseases.

African leaders at the Second Africa Climate Summit voiced growing frustration that global military expenditure - now $2.7 trillion annually and rising 9.4% since 2023 - is crowding out climate finance for the continent most vulnerable to warming impacts. The stark mathematics are sobering: rich nations spend 30 times more on their militaries than on climate finance for vulnerable countries, while Africa receives only $14.8 billion of the $70 billion annually needed for adaptation. Patrick Verkooijen of the Global Center on Adaptation noted that "fiscal space to invest in climate adaptation is smaller by default" as security priorities dominate government budgets following conflicts in Ukraine and Gaza. The summit announced a $50 billion second phase of the Africa Adaptation Acceleration Program, calling on international partners to prioritise grants over loans for a continent already spending nearly three times more on debt service than it receives in climate finance.
