Climate change makes me think of carbon dioxide, but apparently I should also be worrying about dust. There are dust clouds in Namibia so massive they can be seen from space, and recent drought has increased dust in parts of the USA.
Scientists think dust plays a big role in our changing climate, but they don't know for sure, so one group of researchers are planning to find out more.
At the moment climate models don't represent dust accurately, which could make them less useful. The more scientists know about dust, the better we'll understand the future of our climate.
