Answer to Question 1

The warm Mesozoic climate was likely due to increased atmospheric CO2 concentrations and greater equator-to-pole heat transport. The increased CO2 concentrations likely resulted from higher outgassing rates corresponding to increased sea-floor spreading rates, while the cause for the greater equator-to-pole heat transport has been elusive.
