Hey gov"There is a difference between something that is already happening and that billions of people depend on and something that we have NEVER tried and are estimating its results."Climate science has made it's case that CO2 emissions are having a serious effect on climate. It's very comprehensive and is based on empirical facts straddling particle physics, chemistry and thermodynamics as well as determinations of trends derived from observations and modelling (it makes me laugh when deniers say "the science is flawed/crumbling"). Knowing this, we need to curb greenhouse gas emissions by creating and infrastructure that encourages alternatives, which isn't going to happen by itself overnight. In doing so we reduce our dependence on fossil fuels, which is inevitable. We need to wean ourselves off fossil fuels, not throw our hands up saying that we depend on it so to hell with everything else!"That we are pumping CO2 into out atmosphere is accidental. Nobody knew when the combustion engine was invented that it would be a problem and I'm still not sure it is."We may not have known the effects of CO2 then, but we know it now.The majority of reputable climatologists who are actively involved in climate research will tell you that we need to act on this immediately and with wartime urgency if we are to have a chance of averting catastrophic weather events and climate shifts in the near future. However, the denialists strive to pick up on inconsequential aspects of the science and attempt to confuse, obfuscate and delay any action with the premise that "it will cost the economy" (sadly for us and our planets biodiversity, this tactic seems to be working). This group seems to regard CO2 pollution as an entitlement and not a cost to the environment, and that, broadly, is the role of cap & trade/carbon taxing; to enforce an economic view of CO2 pollution.We are sure of what we're doing and why we're doing it. It' snot for global domination, a cash grab, a NWO or the erosion of personal freedoms. It's to preserve the planet for future generations to come.
