Forty years ago, nations adopted the Vienna Convention to safeguard the ozone layer, which shields life on Earth from harmful ultraviolet radiation. This landmark agreement laid the foundation for global efforts to protect both people and the planet. Building on it, the Montreal Protocol successfully phased out ozone-depleting substances, and the Kigali Amendment now targets greenhouse gases. On the International Day for the Preservation of the Ozone Layer (16 September), these treaties together demonstrate how science can drive global cooperation for a safer, healthier future.

The World Meteorological Organization (WMO) has established a new world record for the longest lightning flash – an incredible 829 km (515 miles) in a notorious storm hotspot in the United States of America.

Many disasters, whether man-made or weather-related, are unpredictable. Nevertheless, a growing number of disasters can now be predicted thanks to continuously improving early warning systems. Action before disasters strike can help limit the devastating impact that these have on people and communities everywhere. As extreme weather events are becoming more frequent and humanitarian needs are soaring, it is more crucial than ever to ensure that each dollar goes further. The UN's Food and Agriculture Organization (FAO) promotes anticipatory action to help people in vulnerable situations stay steps ahead and weather the storm.

Performance-based climate finance ties the flow of financial resources directly to the achievement of specific, measurable and independently verified climate results. This clear connection between funding and outcomes increases transparency, which in turn builds trust among all stakeholders involved – from governments and donors to frontline communities working on climate action. Performance-based climate finance also sparks innovation. Since finance depends on the achievement of results, implementers are keen to find the most effective and efficient ways to deliver impact. UNDP is a key enabler of performance-based climate finance worldwide, with extensive experience on climate mitigation.

In the vibrant community of Medina Gounass, Senegal, Modou Fall, also known as the Plastic Man, is dedicated to advocating for a cleaner planet. He raises awareness about the dangers of plastic pollution and educates children on the urgent need for sustainable action to protect the environment.

In Yemen, climate-resilient roads, built "one road at a time" through World Bank-funded projects, help communities withstand extreme weather and climate change impacts.

The UN climate conference in Baku, Azerbaijan, concluded with an agreement calling on developed countries to deliver $300 billion per year to developing countries by 2035 to drastically reduce greenhouse gas emissions and protect lives and livelihoods from the worsening impacts of climate change. “I appeal to governments to see this agreement as a foundation – and build on it,” UN Secretary-General António Guterres said in his statement on COP29.

As climate change impacts intensify, the need for climate services to support mitigation, adaptation and increase resilience has never been higher. In the past five years, there has been progress in provision of this climate information for decision-making, but big gaps remain and investment lags far behind needs, according to a new multi-agency flagship report produced by the World Meteorological Organization (WMO)

Tsunami experts, Rick and Laura, discuss advancements in tsunami warning systems and global preparedness.

The 12th Annual High-Level Meeting of Caring for Climate, hosted by the UN Global Compact, UN Environment and UN Climate Change, will gather leaders from business, government, finance, civil society, and the UN to discuss improving finance flows to support the national climate transition plans. These plans outline how each country would reduce greenhouse gas emissions and adapt to climate change’s impacts. known as the "Finance COP," this year’s COP29 will focus on aligning climate finance with global needs and turning transition plans into actionable investment roadmaps.

On the cold, wet and foggy slopes of the Andes mountains in South America, a unique but fragile ecosystem illustrates the interconnection between the three most urgent global environmental crises we face today: biodiversity loss, climate change and land degradation. Known as páramos (alpine tundras), these high mountain ecosystems are found at altitudes higher than 3,000 metres. Considered sacred by Indigenous Peoples, the páramos of the Andes have been inhabited by humans for the past 15,000 years. However, with over 76,000 families living in the Colombian páramos today, unsustainable development has been pressuring this invaluable and delicate ecosystem. That is why the Global Environment Facility (GEF) Small Grants Programme (SGP), implemented by the United Nations Development Programme (UNDP), launched the Guardians of the Páramos alliance, in partnership with SWISSAID and World Women’s Corporation Colombia. Over the project’s three years of implementation, a total of 2,328 people participated, most of them rural women.

How can social protection help those most vulnerable to the worst impacts of climate change? 

In this episode of ILO's The Future of Work podcast, Kumi Naidoo, a longtime human rights and climate justice activist, and Shahra Razavi, Director of the ILO’s Universal Social Protection department, discuss the issue.

Iceland has created the world's first Glacier Graveyard on the Seltjarnarnes Peninsula, symbolizing the loss of glaciers due to climate change. It features memorial tombstones for glaciers that have melted, such as the Okjökull Glacier. This initiative aims to raise awareness about the rapid disappearance of glaciers worldwide.

The World Meteorological Organization report on the State of the Climate in the South-West Pacific 2023 shows how weather-related disasters are undermining socio-economic development, as well as threatening health, food and water security in the region. The report was launched yesterday and provides a snapshot of climate indicators like temperatures, sea level rise, ocean heat and acidification and extreme weather, alongside risks and impacts. 

Renewable energy solutions are providing a more reliable source of electricity for millions of people in Yemen – and improving their access to essential services.
