Energy from the sun drives the processes that make Earth work in ways that enable life as we know it. Our spinning planet, uses sunlight and oceans to make the weather, with huge circulating ocean currents, dominant wind patterns, and jet streams in the upper atmosphere - all of which affect weather patterns.

Climate change is unsettling these things, and bringing more frequent and intense drought, storms and heat waves. These shifting patterns also affect the established timing , character and duration of the seasons, which causes ecosystems reliant on them to suffer further stress.
