Correct. Increasing CO2, in addition to very tiny (non-tangible) warming effects, is also cooling the earth. 1. It is cooling the upper air faster than we ever thought possible. 2. A warmer earth means the atmosphere's ability to make clouds increases, which mostly help to reflect sunlight and thus cause cooling. 3. Increasing CO2 enables plants to grow with less need for water, which is why deserts are unexpectedly greening -- and more plants means a cooler earth surface.
