Tilt and Seasonal Insolation
						q The hemispheric and seasonal patterns of insolation changes for tilt and precession are fundamentally different. q Insolation changes at high latitudes caused by change in the tilt are in phase between the hemisphere from a seasonal perspective. q For the case of increased tilt, summer insolation maxima in the northern hemisphere occur at the same time in the 41,000-year cycle as summer insolation maxima in the southern hemisphere.
