New Zealand's species have endured sweeping transformations brought by humans and the pests we've introduced.

Scientists say that predicting what will happen with several degrees of temperature rise and other impacts of climate change, ranging from rising seas to wilder weather, is tough.

That's partly because our climate is already variable and partly because there's uncertainty about what other flow-on effects will come that could make the picture even worse.

But we do know that all of our native species and their ecosystems will be affected somehow.
