Deliberate to what end?

This is dogmatic rubbish, and simply not true.
No-one has ever suggested that solar cycles are negligible.
However, when you take into account changes in the earth's orbit, and solar cycles, the warming measured is greater than is expected if these are the only driving factors.

1. The climate acts and has always acted in natural cycles
2. The current theory of CO2 causing global warming is unproven - even the IPCC acknowledges this
3. For 30 years the scary predictions about earths fever, drastic sea level rise etc is not based on observation but on computer model projections. If we still dont know everything about the climate then how can these models be accurate. If the climate continues to behave opposite to the climate models (the wolrd is cooling and not warming) then we have to say the models are wrong.
4. We need rigorous scientific debate on the topic. If as the natural climatic observations and numerous scientists say we have entered a period of 20-30 years cooling and we are spending trillions on warming - we will be unprepared for the cooling, many lives will be lost (see little ice age).
5. Extreme weather is a result of cooling and not warming.
1. Agreed, however it is not a simple up/down cycle, there are many factors with different timescales.
And this does not mean that humans cannot effect the climate.
2. No. The way in which carbon dioxide causes the planet to retain heat is very well understood. It is the natural greenhouse effect, caused by the atmosphere (mainly CO2 and water) absorbing strongly in the infra-red region. Increasing atmospheric carbon dioxide increases the cross section for absorption.
3. No-one says they are accurate, I've addressed this earlier in the thread.
However, you seem to be under the impression that we say the earth is warming based on predictions of models. This is not true. The earth's temperature is an observable. It is rising, that is observed.
The question is whether that is happening because of human carbon emissions increasing atmospheric CO2 or whether it would have happened anyway.
4. Climatic observations do not and cannot say we have entered a period of "20-30 years cooling". An observation tells us what is happening now. No more.
5. I suppose that depends on how you define extreme weather.
