I am a palaeoecologist at the Open University. My research involves reconstructing how our planet has changed over longer time scales in the past (1-2 million years). At first glance my research does not seem entirely relevant to current climate change but in fact it is integral. The climate system is hugely complicated and we still don’t fully understand how all the aspects work or how they interact together. One way of learning how the system operates is to simply observe it. The longer you observe it; then the better you will understand how it works and what are the possibilities for how it may change.
