There is no science which shows any measurable effect of human emissions on climate.
Professor Carter gives an excellent summary of the failed hypothesis of the climate fraud promoters regarding the effect of CO2 in the atmosphere.
The IPCC advances three main categories of argument for a dangerous human influence on climate. The first is that, over the 20th century, global average temperature increased by about 0.7C, which it did, if you accept that the surface thermometer record used by the IPCC is accurate. More reliably, historical records and many geological data sets show that warming has indeed occurred since the intense cold periods of the "little Ice Ages" in the 14th, 17th and 19th centuries. The part of this temperature recovery which occurred in the 20th century is the "global warming", alleged by climate alarmists to have been caused by the accumulation of human-sourced CO2 in the atmosphere
However, our most accurate depiction of atmospheric temperature over the past 25 years comes from satellite measurements (see graph below) rather than from the ground thermometer record. Once the effects of non-greenhouse warming (the El Ni๑o phenomenon in the Pacific, for instance) and cooling (volcanic eruptions) events are discounted, these measurements indicate an absence of significant global warming since 1979 - that is, over the very period that human carbon dioxide emissions have been increasing rapidly. The satellite data signal not only the absence of substantial human-induced warming, by recording similar temperatures in 1980 and 2006, but also provide an empirical test of the greenhouse hypothesis as understood by the public - a test that the hypothesis fails.

the pause in global warming ceased since this paper was written, but the science is not affected. There is no basis for the assertion that human emissions cause warming.
Smarten up your ideas, Mike, your assertions about human emissions are baseless, and you are supporting the climate fraud.
