Climate change is perhaps the greatest challenge humanity has ever faced.
It affects every corner of our planet – from the poles to the tropics, and from the mountains to the oceans. People and nature worldwide are already feeling the effects: water supplies are shrinking, extreme weather events increasing in frequency and intensity, forests burning, and coral reefs dying.
Governments and communities are coming together to act – and we can still escape the worst impacts of climate change, and build a safer future for all.
But we need to do more, and faster. Most importantly, we need to step up efforts to switch from using fossil fuels – the biggest cause of climate change – to clean, renewable energy. And we need to help people and nature adapt to the inevitable changes ahead.
