All IPCC definitions taken from Climate Change 2007: The Physical Science Basis. There's no empirical evidence "There is no actual evidence that carbon dioxide emissions are causing global warming.
Working Group I Contribution to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, Annex I, Glossary, pp. Note that computer models are just concatenations of calculations you could do on a hand-held calculator, so they are theoretical and cannot be part of any evidence." (David Evans)The proof that man-made CO2 is causing global warming is like the chain of evidence in a court case.
At night, it can plunge to minus 173°C, or -279.4°F.
In comparison, the coldest temperature on Earth was recorded in Antarctica: −89.2°C (−128.6°F).
Humans, plants and animals can’t tolerate the extremes of temperature on Earth unless they evolve special ways to deal with the heat or the cold.
Nearly all life on Earth lives in areas that are more hospitable, where temperatures are far less extreme.The laws of physics tell us that without the atmosphere, the Earth would be approximately 33°C (59.4°F) cooler than it actually is.This would make most of the surface uninhabitable for humans.That information gives us the next piece of evidence; CO2 has increased by nearly 43% in the last 150 years.The final piece of evidence is ‘the smoking gun’, the proof that CO2 is causing the increases in temperature.CO2 keeps the Earth warmer than it would be without it.Humans are adding CO2 to the atmosphere, mainly by burning fossil fuels.Yet the Earth and the moon are virtually the same distance from the sun, so why do we experience much less heat and cold than the moon? The moon doesn’t have one, so it is exposed to the full strength of energy coming from the sun.At night, temperatures plunge because there is no atmosphere to keep the heat in, as there is on Earth.Enter a term in the search box to find its definition.Use the controls in the far right panel to increase or decrease the number of terms automatically displayed (or to completely turn that feature off).
