An increase in CO2 is said to increase the radiative effect of the greenhouse gases in the atmosphere.
When we bring our results together, an interesting picture emerges of the combined effect of greenhouse gases and the effects of the ozone hole on climate at the poles.
The world's oceans are like brakes slowing down the full effects of greenhouse gas warming of the atmosphere.
Recent temperature increases also square with the known effects of greenhouse gases.

Understanding the economic effects of greenhouse gas (GHG) emission reductions is essential to assessing climate change scenarios.
The full effects of the greenhouse gases emitted in 2016 will only be felt in 2030.
However, albedo modification would only temporarily mask the warming effect of greenhouse gases and would not address atmospheric concentrations of CO2 or related impacts such as ocean acidification.
Unlike more mature parts of the science (such as the radiative effect of greenhouse gases), there is much less context available to relate to these new pieces of science.
One of the methods anthropogenic global warming advocates (scientists and bloggers) use to illustrate the assumed effects of greenhouse gases on global temperatures is to illustrate the divergence between the linear trends of global temperatures and a scaled ENSO index such as NINO3.4 SST anomalies.
Specifically, some scientists believe it should be possible to offset the warming effect of greenhouses gases by reflecting more of the sun's energy back into space.
As recently as June 2008 Dr. John Nicol published a detailed scientific analysis of the heating effects of greenhouse gases which supports the arguments of Dr. Hug and Dr Barrett.
PNNL's model scenario limits the heat - trapping effect of greenhouse gases in the atmosphere to levels only 65 percent of what they would reach if no future emissions controls are implemented.
He has published over 100 articles on topics including the climatic effects of greenhouse gases, stratospheric ozone depletion, and small particles.
If the temperature below is warmer than the local temperature, IR radiation that is re-radiated is less than is absorbed, the net effect of the greenhouse gases is to warm that layer.
The claim that climate models systematically overestimate the warming effects of greenhouse gases seems to be unfounded.
However, the warming effect of greenhouse gases such as carbon dioxide will grow sufficiently to overcome the combined impact of various natural climate cooling factors, journalists on a telephone news conference were told last week by Gavin Schmidt, director of NASA's Goddard Institute of Space Studies.
If it includes a requirement to consider the life - cycle effects of greenhouse gases associated with the coal to be extracted, it might tip the scales against the new mine.
Solar radiation management attempts to offset effects of greenhouse gases by causing Earth to absorb less solar radiation.
Still, Holdren's slight of his letters — in which he cited alleged manipulation and mishandling of decisions ranging from the health effects of greenhouse gases to fuel standards for cars — gave him a platform from which to criticize what he called the Administration's «arrogance, ignorance, and incompetence» toward science.
Just like the predictions then of doomsday coming in form of «nuclear winter», nobody can escape being exposed today to the projection of the ominous effects of greenhouse gases proclaimed by the «experts», the news media, politicians and, of course, Hollywood.
That gives you some idea of the basic nature of infrared effects of greenhouse gases, but it still won't address some of the subtler points concerning radiative transfer and the effect of band saturation — except insofar as band saturation is used in the explanation of why the radiative effect of CO2 is roughly logarithmic.
The orthodox explanation for that one is that the cooling effect of white aerosols such as sulphates — released from coal and oil burning — was masking the warming effect of greenhouse gases until various clean air acts allowed the anthropogenic warming trend to re-emerge.
It is varying of the slopes and heights which changes the rate of non-radiative energy flows up from the surface and thereby negates the thermal effect of greenhouse gases.
Design / methodology / approach: The analyses are based on the IPCC's own reports, the observed temperatures versus the IPCC model - calculated temperatures and the warming effects of greenhouse gases based on the critical studies of climate sensitivity (CS).
However, if one converts the total effects of all greenhouse gases, aerosols, etc. into an equivalent increase in CO2 concentration (by reference to their effective radiative forcing RF, that from a doubling of CO2 being F2xCO2), then what you suggest would be pretty much in line with the generic definition of TCR in Section 10.8.1 of AR5 WGI:
