Climate change is a really real present risk. The climate has already changed because of the influence of humans. And it's going to continue to change and that pace of change is going to speed up, so the risk to sites like Skara Brae and other sites around Orkney, it's real, it's here, it's happening. But it shouldn't all be doom and gloom and despair. There is an opportunity to still do something about it and to avoid the worst possible consequences of climate change.
