The 33 degrees of so-called greenhouse gas warming is a number created by a clique of climate researchers who claim it proves the existence of the "greenhouse gas effect." But this number is not obtained by actual measurement but as the product of crossing two temperatures obtained by different metrics.
The first of these number is 288K (15 degrees Celsius) and is an average of the ground temps from global weather stations. It is a scalar metric value. The second number is 255K (-18 Celsius) and is a measure of the outgoing infrared radiation from our atmosphere back to outer space. It is a vector metric. But Physics 101 tells us it is not permitted to cross scalars with vectors.
Nonetheless, in the 1980's Dr. James Hansen, head of the Goddard Institute of Space Science (GISS) at NASA did just that. [1 & 2]. Thereafter the "33 Degrees" number became iconic within the climate science community proclaiming dangerous man-made global warming. The IPCC AR4 published the disputed number in their 2007 Report.

More than 50 scientists at Principia Scientific International exposed this error in 2012 (www.principia-scientific.org). [4]

[3] Le Treut et al., "Chapter 1: Historical Overview of Climate Change Science", FAQ 1.1, p. 97, in IPCC AR4 WG1 2007: "To emit 240 W m-2, a surface would have to have a temperature of around −19 °C. This is much colder than the conditions that actually exist at the Earth's surface (the global mean surface temperature is about 14 °C). Instead, the necessary −19 °C is found at an altitude about 5 km above the surface."

Does the greenhouse effect occur on the moon or the earth?
The greenhouse effect comes about when greenhouse gases in the atmosphere capture heat rising from the surface of the planet. As the moon has no atmosphere, it could not have a greenhouse effect. So the answer is: The earth.
When did the Greenhouse effect start?
The Greenhouse effect started long before humans were on Earth. The Greenhouse effect is only intensified by the presence of humans.
What is a sentence with greenhouse effect?
The greenhouse effect is the natural way that the Earth keeps warm. Too many extra greenhouse gases turn the greenhouse effect into an enhanced greenhouse effect. The enhanced, or accelerated, greenhouse effect is causing global warming.
How does the greenhouse effect change your world?
The natural greenhouse effect keeps the earth warm enough for life. The enhanced greenhouse effect is causing global warming.
The greenhouse effect is the natural warming in earth's what?
In the Earth's Geosphere.
Does the greenhouse effect occur on the moon or the earth?
The greenhouse effect comes about when greenhouse gases in the atmosphere capture heat rising from the surface of the planet. As the moon has no atmosphere, it could not have a greenhouse effect. So the answer is: The earth.
How does the greenhouse effect earth?
the greenhouse effect influences the earth by cause global warming. The reason why is because the greenhouse effect, traps heat in our atmosphere, causing the earth to heat more than usual.
Is the enhanced greenhouse effect essential for life on earth?
The greenhouse effect is essential to life on earth. The enhanced greenhouse effect is not. In fact if it is enhanced too quickly it can be harmful to life.
What is the temperature of it atmosphere is increased by the greenhouse effect?
Both Earth and Venus have increase temperature due to a greenhouse effect. Venus has a much stronger greenhouse effect than Earth does.
Where on earth besides in a greenhouse does the greenhouse effect occur?
In the atmosphere. The greenhouse effect refers to the situation in the atmosphere where gases hold on to the heat rising from the earth.
When did the Greenhouse effect start?
The Greenhouse effect started long before humans were on Earth. The Greenhouse effect is only intensified by the presence of humans.
What planet has an atmosphere with a greenhouse effect?
EarthVenusMarsThe greenhouse effect occurs on every planet with an atmosphere (including Earth). On Venus, there is a runaway greenhouse effect causing temperatures high enough to melt lead.Mars has a greenhouse effect that is weak because of its thin atmosphere.
What is a sentence with greenhouse effect?
The greenhouse effect is the natural way that the Earth keeps warm. Too many extra greenhouse gases turn the greenhouse effect into an enhanced greenhouse effect. The enhanced, or accelerated, greenhouse effect is causing global warming.
Is the greenhouse an effect on earth?
Yes.
What is the source of radiation for both the earth's atmosphere and the greenhouse effect?
The sun is the source of radiation for both the earth's atmosphere and the greenhouse effect.
Greenhouse Effect that prevents a planet's heat from escaping?
This is true. The greenhouse effect on earth holds back heat escaping from the earth.
Does earth radiating mostly infrared light cause the greenhouse effect?
Yes. The infrared radiation from the surface of the earth is captured by the greenhouse gases in the atmosphere. This causes the greenhouse effect.
