That is an attempt at making a mockery of the Scientific process. New evidence does not have to concord with current consensus, it is used to support existing observations/evidence or not. A consensus is something that emerges from the body of observations.
Making a mockery of the scientific process? Not at all. You seem to have missed the point again. Once a consensus has developed there is usually a strong resistance to that consensus being broken. That is simply human nature. People have careers and reputations to protect, and need employment in their chosen career to support themselves and their families.
The complexity and chaotic nature of weather and climate changes, and the long timescales involved before a consistent trend can be observed, make it impossible to apply the rigorous procedures of the scientific methodology of verification and falsification.
Just as it's impossible to verify that small increases in a particular trace gas, such as CO2, will have long-term, harmful effects, it's also impossible to falsify that hypothesis. Therefore scientific certainty on the issue is not possible.
The people who are truly making a real mockery of the scientific process, are those who are expressing certainty on the issue, not only that increases in CO2 levels are the main cause of the current, slight warming period, but also that such warming will be bad for humanity in general. Got it?
It's also not helpful to deny simple chemical properties of elements or plain physics and waste huge amounts of time and tax payer's money on "fully investigating" largely irrelevant alternatives.
Who has been denying basic chemical properties of elements, or basic physics? Have I ever denied that CO2 is a greenhouse gas? I'm quite capable of understanding that CO2, Nitrous Oxides, Methane, Water Vapour, and so on, are better able to absorb the lower frequencies of the Electromagnet Spectrum, known as infrared waves which are associated with heat. Greenhouse gases are essential for life on our planet.
CO2 in particular is a potential asset which we would exploit if we were smart enough.
