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."

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.
the greenhouse effect is a global phenomenon.
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.
Most of the greenhouse effect occurs in the troposphere.
The greenhouse effect has been a natural phenomenon on Earth for millions of years. However, human activities, such as burning fossil fuels, have significantly increased the concentration of greenhouse gases in the atmosphere since the Industrial Revolution, intensifying the greenhouse effect and leading to global warming.
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.
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.
Both Earth and Venus have increase temperature due to a greenhouse effect. Venus has a much stronger greenhouse effect than Earth does.
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.
In the atmosphere. The greenhouse effect refers to the situation in the atmosphere where gases hold on to the heat rising from the earth.

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.
Yes.
This is true. The greenhouse effect on earth holds back heat escaping from the earth.
The normal greenhouse effect keeps the earth warm enough for life.The enhanced, or accelerated greenhouse effect, is causing global warming.
The earth has always had the greenhouse effect. It is what stops us from freezing so far away from the sun.
