The, so-called, climate consensus say people cause climate change. This self-styled consensus say that 90% of modern climate change is caused by humanity. Mainly by burning, carbon-based, fossil fuels to make carbon dioxide gas which remains in the atmosphere for centuries (according to them). That this carbon dioxide, a so-called greenhouse gas, warms the atmosphere by 'trapping heat', slowing the release of infrared energy to space; which they call the greenhouse gas effect, GHGE. According to their theory and model, an imbalance in radiation in and out of the earth causes climate change. The climate consensus say earth absorbs more radiation than it emits.
There is a universal consensus on the main mechanism for earth's warming (it is the sun); and the main mechanism for earth's cooling (loss of outgoing longwave radiation, OLR, to space). When the balance is in favour of the sun (more sun in than OLR out) earth warms. When the balance is the other way - more OLR out than sun in - earth cools. There is no balance, as such, earth is always warming or cooling; but so slowly it's fooled people into thinking the climate is in balance; AKA in equilibrium.
Recent research shows since 1985 there has, indeed, been a radiative imbalance; but the imbalance is in exactly the wrong direction for the climate consensus. Research shows earth cooling, not warming. There is an imbalance between earth's energy in (due to solar warming) and energy out, due to OLR. OLR has increased in the last 33 years. This means earth is cooling.
I suppose I haven't actually refuted 'man-made climate change'. I refuted climate warming due to more CO2 in the atmosphere.

- The residence time of carbon dioxide in earth's atmosphere is no greater than 9 years. Not centuries as the climate consensus tell us.
