How do changes in cloud cover affect global temperatures?
Changes in cloud cover significantly affect global temperatures by altering the Earth’s energy balance. Increased cloud cover generally leads to a cooling effect because clouds reflect sunlight back into space, reducing the amount of solar radiation that reaches the Earth’s surface. For instance, studies have shown that low-level clouds can reflect up to 90% of incoming solar radiation, which can lower surface temperatures. Conversely, decreased cloud cover allows more solar radiation to penetrate, resulting in warming. Research indicates that a 1% decrease in cloud cover can lead to an increase in global temperatures by approximately 0.5 degrees Celsius. Thus, variations in cloud cover play a crucial role in regulating the Earth’s climate system.
