As of 12, the warming effect of longlived greenhouse gases in Earth's atmosphere had increased by approximately 47% compared to 1990 Relative to preindustrial times, today's atmosphere absorbs an extra 3 watts of energy per square meterEven if greenhouse gas concentrations stabilized today, the planet would continue to warm by about 06°C over the next century because of greenhouses gases already in the atmosphere See Earth's Big Heat Bucket, Correcting Ocean Cooling, and Climate Q&A If we immediately stopped emitting greenhouse gases, would global warming stop?Ozone is also a greenhouse gas, but it differs from other greenhouse gases in several ways The effects of ozone depend on its altitude, or where the gas is located vertically in the atmosphere Most ozone naturally exists in the layer of the atmosphere called the stratosphere, which ranges from approximately 6 to 30 miles above the Earth's
