Why is orbital forcing not considered a viable mechanism for explaining the 0.85-1.0 °C warming over the past 125 years?     Tectonics are more important than orbital variations on Earth s climate     The rate of temperature change from orbital forcing is too slow and in the wrong direction     Sunspots drive climate, but only when the Earth is at perihelion     Orbital forcing only affects climate during ice ages
