Global warming is caused by increased levels of carbon dioxide and other greenhouse gases trapping heat in the atmosphere. This is raising Earth's temperatures and causing environmental effects worldwide like melting ice, more extreme weather, and rising sea levels. Greece is experiencing higher wildfire risks that threaten forests, economic impacts on agriculture as the ground grows drier, negative effects on tourism from extremely hot summer temperatures, and increased health problems from heat. Proposed solutions include transitioning to renewable energy, reducing carbon footprints, favoring green transportation, and lowering emissions from deforestation.
