New Brighton Climate Action Plan 1 -4 <br />What Causes <br />Climate Change <br />Earth’s Infrared Energy <br />When sunlight strikes the Earth, it warms the surface and <br />becomes heat energy – or infrared energy. This infrared <br />energy then radiates back towards space. <br />How Greenhouse Gases (GHGs) Trap Heat <br />GHGs such as carbon dioxide and methane are central in creating the "greenhouse effect" that <br />traps the sun's heat. These gases interact with the infrared energy radiating from the Earth. <br />Human activities like burning fossil fuels and deforestation have increased GHG <br />concentrations, amplifying this effect. The additional trapped heat leads to global warming, <br />affecting weather patterns, melting ice, and raising sea levels, all contributing to climate change.
