Biodiversity and Climate Change

Our planet’s climate is changing. The Earth is warming, sea levels are rising, rainfall and snowfall patterns are changing, and extreme weather events are becoming more frequent and more intense.

The physical changes brought about by climate change (e.g. temperature increases) can have major impacts on human societies by reshaping our lifestyles, economies and industries. And after decades of debate, politicians and the general public now acknowledge climate change as a global environmental crisis. People are aware that something needs to be done. It’s often young people who call on political, scientific and business leaders to deal with climate change.

But there's another global environmental crisis that is just as important, urgent and complex as climate change that doesn’t yet get so much attention - the biodiversity crisis.

In fact, biodiversity and climate change are closely linked, each affecting the other. Biodiversity is threatened by climate change, but maintaining biodiversity and healthy ecosystems can mitigate climate change, protect against its impacts and help us to adapt. For example, forest and ocean ecosystemss store carbon, reducing the levels of greenhouse gases in the atmosphere.

Climate change is defined as a change either in the average state of the climate or in its variability, lasting for an extended period, typically decades or longer. It is being caused by increased levels of greenhouse gases in the atmosphere, which act like the glass roof of a greenhouse, trapping heat and warming the planet.

Greenhouse gases such as water vapour, carbon dioxide, ozone and methane occur naturally and help maintain a temperature range suitable for life. However, emissions resulting from human activities, such as the burning of fossil fuels and land-use changes, have raised the level of greenhouse gases in the atmosphere well above the natural levels. As a result, the Earth’s surface and lower atmosphere are warming. If human-induced emissions continue unchecked, the effects will be profound.
