WebbTable VII shows the change in the globally averaged radiative forcing, which is dominated by the longwave radiative forcing of 0.55 and 0.5 W m −2 in January and July, respectively. Ozone changes increase the solar flux into the troposphere while slightly reducing the longwave flux, resulting in a net warming of 0.14 and 0.08 W m −2 for January and July, … WebbThings that change the balance between incoming and outgoing energy in the climate system are called forcings. Natural forcings include volcanic eruptions. Manmade forcings include air pollution and greenhouse gases. A climate forcing, such as greenhouse gas increases, may trigger feedbacks like the loss of sunlight-reflecting ice. cisco business 150ax 価格
