Photocomposition: the globe as a lit match

Hottest year on record

2024 was officially the hottest year on record, topping an extraordinary streak of record-breaking temperatures, with the past ten years, 2015-2024, the ten warmest years on record. “Blazing temperatures in 2024 require trail-blazing climate action in 2025,” the UN Secretary-General said. “There's still time to avoid the worst of climate catastrophe,” he said. “But leaders must act – now.” Updated national climate action plans, due this year, must include drastic cuts in greenhouse gas emissions to limit long-term global temperature rise.

Launch of the International Year of Glaciers Preservation

Glaciers are crucial for regulating the global climate and providing freshwater, essential for billions of people. However, due to climate change, these vital resources are rapidly melting. The International Year focuses on providing concrete recommendations to address climate change impacts, advocating and raising funds for more ambitious action, and convening countries and communities affected by glacier loss.

International Day of Clean Energy

Energy is at the heart of the climate challenge – and key to the solution. To avoid the worst impacts of climate change, greenhouse gas emissions need to be reduced by almost half by 2030 and reach net zero by 2050. To achieve this, we need to end our reliance on fossil fuels and invest in alternative sources of energy that are clean, accessible, affordable, sustainable, and reliable.

World Wetlands Day

Climate change is heavily impacting wetlands through more severe and frequent droughts and increased evaporation due to higher temperatures. At the same time, the loss of wetlands could worsen the impact of climate change, as these ecosystems provide essential services that mitigate the effects of climate change.
