Well, it seems that not everyone is sure that "climate change" is really "climate change". Maybe they just need to admit they really do not have enough data to say, and approach it from some other direction if it is really a concern. Not being a scientist, I can be open to a discussion about why increased CO2 may be a problem, since it also goes in hand with wiping out the worlds largest carbon sink (amazon basin forests). There may be issues that could need addressing, just not at the point of a spear, screaming in rage and fear..take note climate change aficionados..your approach needs some tweaks.
