there are many greenhouse gases, including carbon dioxide (co2), methane (ch4). and vaporized water (h2o). these and other greenhouse gases warm the earth primarily by: group of answer choices making more clouds, because clouds block the radiation from the planet, which is why cold, frosty nights are rare during cloudy weather. absorbing some of the infrared radiation emitted from the earth. raising the atmospheric pressure, because squeezing air warms it, as we saw at the redwoods. preventing convection currents that take heat aloft, in the same way that the glass of a greenhouse stops convection currents and so makes the air in the greenhouse warmer.
