Greenhouse effect on other planets - Energy Education
WebThe reflected radiation, 102 W·m -2, shown at the far left accounts for the Earth’s albedo, 0.30. Of the remaining unreflected radiant energy in the near ultraviolet, visible, and short wavelength infrared, about 30% (78 W·m -2 out of 239 W·m -2) is absorbed by gases in the atmosphere (mainly O 3, O 2, H 2 O, and CO 2) and warms the atmosphere. WebFeb 14, 2003 · Without this natural phenomenon, average temperatures on Earth would be 30 degrees lower than the current 15 degrees Celsius. Unfortunately, fossil-fuel combustion and deforestation release large amounts of greenhouse gases to the atmosphere, strengthening the greenhouse effect. earthdata下载数据教程
What Is the Greenhouse Effect? - American Chemical Society
WebThe small percentage of greenhouse gases is still enough to raise the Earth's average temperature by 33°C! With no greenhouse gasses, the average temperature of the Earth would be -18°C. Life on Earth needs … WebIf there were no greenhouse effect, the Earth’s average surface temperature would be a very chilly -18°C (0°F) instead of the comfortable 15°C (59°F) that it is today. See Climate and Earth’s Energy Budget to read more … WebWithout 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. Since the 1880s, the average surface temperature has risen by 0.8°C with the … Although the greenhouse effect is a natural phenomenon, there are concerns with … earthdata注册不上
