\begin{abstract}
Hello, we are Professor Tim Lenton and Dr Damien Mansell, climate
scientists from the University of Exeter. Together, our research looks
into the science of Climate Change. We're also passionate educators and
have, for the last 5 years, produced free online courses that look at
the Challenges and Solutions of climate change. It can be easy to feel
disillusioned by climate change and as if there is nothing we can do,
but that's not true and there are many ways we can take action into our
own hands. Tim: My research has looked at the evolution of the Earth
System and, in particular, tipping points in the climate system. I've
recently begun focussing on detecting early warning signals for these
tipping points. If we are able to detect when a system is close to
tipping, we can better assess the solutions that can prevent
catastrophic climate change or reduce the impacts. Damien: I study the
contemporary cryosphere (the world's ice) and how this is changing with
recent climate warming. My research uses satellite data and the
development of new remote sensing techniques to study cryosphere
instabilities. I'm also interested in the use of technology in teaching
and education, from developing virtual field trips to these online
courses. Our new course `Climate Change: Solutions' discusses and
applies the theme of Climate Action to the UN Sustainable Development
Goals. We look at a range of solutions, from changing the way we produce
energy to the way we farm, and explore where different options might be
viable around the world. In particular, we'll be focussing on the SDGs
of Life below Water, Life on Land and Sustainable Cities and
Communities. In this AMA, we will be joined by our facilitator team from
the University of Exeter to help answer your burning questions about all
things solutions! Ask us anything! We'll be back at 11:00 am ET to
answer your questions, Ask us anything!%
