Cyclical variations in Earth’s tilt and orbit – occurring at 23,000-, 41,000- and 100,000-year intervals – are known to strongly influence our planet’s long-term climate; they are associated with the coming and going of ice ages that also takes place about every 100,000 years. A new study published in the journal Geophysical Research Letters has revealed that the intensity of volcanic activity at deeply submerged mid-ocean...
