World Mountain Day

Healthy mountain ecosystems help mitigate the impacts of climate change. Mountain forests and grasslands cool local temperatures, increase water retention, store carbon from the atmosphere, and reduce the risks of erosion and landslides. But mountains are under threat from climate change. Rising temperatures also mean that mountain glaciers are melting at unprecedented rates, affecting freshwater supplies downstream for millions of people.

Learn more about how what we eat, and how that food is produced, affects the environment here.

World Migratory Bird Day

Under the theme, ¡°water and its importance for migratory birds,¡± World Migratory Bird Day 2023 calls attention to how the increasing human demand for water, pollution, and climate change, are having a direct impact on the availability of clean water and the conservation status of many migratory birds. Learn more about how climate change impacts the world¡¯s water here. 

International Day for Disaster Risk Reduction

Climate change is causing more frequent and extreme weather events, resulting in widespread adverse impacts and related losses and damages to nature and people. These impacts are often experienced most by those who have contributed the least to the climate crisis, which exacerbates existing inequalities. The Early Warnings for All (EW4All) initiative aims to help break the cycle of disaster and growing inequality and to ensure everyone on earth is covered by early warnings in the next four years. Learn more about EW4All here.

International Day of Clean Air for Blue Skies

Air pollution and climate change are closely linked. The fine particles that pollute our air mostly come from human activities, such as burning fossil fuels for transport or electricity. Switching to clean sources of energy, such as wind and solar, thus helps address not only climate change but also air pollution and health. Learn more about renewable energy here.
