Unless you are so crazily arrogant that you believe we can dial in some optimal global temperate like setting the thermostat in our homes, we have two main choices when it comes to earths temperature: Ice-Ages and interglacial periods.
The history of the planet is ice-ages, but between each one are nice warm interglacial periods. We are currently enjoying one of those nice warm periods. Go outside and look around. Trees, flowers, grass, animals, cities, homes, lakes, etc. But go back ~20,000 years (a mere eye blink in Earth time) and this is what your local northern skyline looked like:
