These changes caused glaciers of continental proportions (ice sheets) to repeatedly expand and contract across northern regions of North America, Europe and Asia. Many use the fact that there have been record snowfalls and polar vortexes in recent years as evidence against climate change, but climate change is far more complex than a simple warming of the planet.
