A positive look at what we can do to reverse the damage we have done to our atmosphere. In this book Broeker explains how we need to clean up after ourselves comparing it to when sanitation was introduced to cities and soon diseases that had been rife where no longer a problem. Not only do we need to reduce our carbon emissions, but clean up, using “artificial trees” which would remove CO2 from the atmosphere. Quite when and how this might happen is still to be decided but this is a fascinating insight into how climate changes and how we effect it.
