How does Earth's surface get heated without the presence of greenhouse gases in the atmosphere and greenhouese gases trap heat in the atmosphere, and what effect does this have on climate?
With all respect, sir, basic physics. I.e., Seinfeld and Pandis, Atmospheric chemistry and physics, or the reports of the International Panel on Climate Change.
Without the greenhouse effect, Earth's temperature would be below freezing. It is, in part, a natural process. However, Earth's greenhouse effect is getting stronger as we add greenhouse gases to the atmosphere. That is warming the climate of our planet.'Greenhouse gases' are crucial to keeping our planet at a suitable temperature for life. Without the natural greenhouse effect, the heat emitted by the Earth would simply pass outwards from the Earth's surface into space and the Earth would have an average temperature of about -20°C. Without the influence of the greenhouse effect on our planet, the average surface temperature would be 255 Kelvin - which can also be expressed as -18°C or 0°F. If this were the case, water on Earth would freeze and life as we know it would not exist. Without the greenhouse effect, Earth's temperature would be below freezing. It is, in part, a natural process. However, Earth's greenhouse effect is getting stronger as we add greenhouse gases to the atmosphere. That is warming the climate of our planet. Extreme Cold Temperatures: Without the greenhouse effect, Earth's atmosphere would lack the ability to trap heat from the sun, resulting in a much colder climate. Average global temperatures would plummet, potentially leading to a planet covered in ice and snow, similar to the conditions seen on Mars. Global average temperature at the present time is around 60 Fahrenheit. With NO greenhouse effect, the temperature on earth would average around zero Fahrenheit, and almost all the water would be frozen almost all the time. So we need the water vapor and carbon dioxide in the atmosphere to trap some of the sun's heat. The level of carbon dioxide in Earth's atmosphere has been rising consistently for decades and traps extra heat near Earth's surface, causing temperatures to rise. Earth's greenhouse gases trap heat in the atmosphere and warm the planet. The main gases responsible for the greenhouse effect include carbon dioxide, methane, nitrous oxide, and water vapor. In addition to these natural compounds, synthetic fluorinated gases also function as greenhouse gases. Solar energy absorbed at Earth's surface is radiated back into the atmosphere as heat. As the heat makes its way through the atmosphere and back out to space, greenhouse gases absorb much of it. Certain gases in the atmosphere absorb energy, slowing or preventing the loss of heat to space. Those gases are known as “greenhouse gases.” They act like a blanket, making the earth warmer than it would otherwise be. This process, commonly known as the “greenhouse effect,” is natural and necessary to support life. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases. As the surface warms up, it emits infrared radiation. Greenhouse gases in the atmosphere absorb some of this infrared radiation, preventing it from escaping directly into space. Rather than absorbing all the heat, greenhouse gases re-emit some of it in all directions, including back towards the Earth's surface. Greenhouse gas molecules in the atmosphere absorb light, preventing some of it from escaping the Earth. This heats up the atmosphere and raises the planet's average temperature.
