  In this paper we propose a straightforward method for understanding the
thermodynamics of black holes in de Sitter space, one that will allow us to
study these black holes in a way that is analogous to the anti-de Sitter case.
As per usual, we formulate separate thermodynamic first laws for each horizon
present in the spacetime, and study their thermodynamics as if they were
independent systems characterized by their own temperature. That these systems
are not entirely independent and various thermodynamic quantities in them are
in fact "correlated" is reflected by the fact that their thermodynamics can be
captured by a single Gibbs free energy-like thermodynamic potential. This
quantity contains information about possible phase transitions in the system
and allows us to uncover a rich phase structure for de Sitter black holes. In
particular, we discover reentrant phase transitions for Kerr-dS black holes in
six dimensions, a phenomenon recently observed for their six dimensional AdS
cousins.
