Climate Change

Climate change — caused by human activities like burning fossil fuels, deforestation, and industrialization — is one of the most urgent challenges facing our planet. These activities increase greenhouse gas emissions, trapping heat in the atmosphere and disrupting global climate systems. The impacts are far-reaching, from more frequent extreme weather events to rising sea levels and ecosystem shifts. Tackling climate change will require a sustained commitment to cutting emissions, transitioning to renewable energy, and strengthening resilience in vulnerable communities worldwide.
