Are we still in a haze of denial?
Planet Earth is warm enough to sustain life thanks to the greenhouse gases in the planet’s atmosphere that hold heat. Appropriately named, these gases trap heat inside the planet’s atmosphere, making the average temperature on Earth 59 degrees Fahrenheit (15 degrees Celsius). Humans have increased the amount of greenhouse gases in the atmosphere by about 35 percent. Simple math – the more greenhouse gases in the atmosphere, the warmer the average temperature gets.
