The CAGW discourse could be less contentious if climate alarmists tamed their arrogance. Here is some humble advice on how this could be achieved:1. Accept, off the bat, that Earth's climate system is extremely complex and thus that neither you, nor anybody else fully understands it.2. Don't try to frame EVERYTHING that happens as "consistent with what you would expect from a warming planet." This reduces your credibility or worse, makes you sound like a clown.3. If your premise is that increasing concentrations of CO2 in the atmosphere are a serious problem then BEHAVE as if you believe this is true. You don't need to completely eliminate your fossil fuel use (an impossible feat for you as for anybody else) but at least engage in token actions such as eliminating all air travel.4. This is a critical one. Again, if CO2 is a very serious issue, then you need to become a card carrying nuclear power advocate. And if you are already a closet nuclear supporter, then you need to come out.5. Even if it is painful for your followers, you should educate them in the uselessness of solar panels and wind turbines to take us to a low CO2 global economy.6. Maybe long term fossil fuels could be significantly displaced by nuclear power, but today they are indispensable to combat poverty. Thus, carbon taxes are not only a very bad idea, but also one of the cruelest things governments can implement.7. You should never close your mind to new facts and data. You should even be open to recanting your AGW beliefs if reality ends up not agreeing with them.Thank you.Feel free to add to the conversation in Twitter: @luisbaram
