(1) You ask for us to lie?  Climate is not stable, and any model that says it is is clearly broken.  Instead you have to produce the best models you can that can explain both the past and project the future.  Then test those models.  Those models uniformly project human-caused global warming, and are passing various kinds of sanity checks.<p>(2) You want us to oversimplify?  Climate is still not stable, and CO2 isn&#x27;t the only thing that is involved.  The main cause for the start&#x2F;end of ice ages are orbital shifts.  CO2 rise was a lagging result, that then amplified the warming.<p>(3) You still want us to oversimplify?  Aerosols are known to cause cooling, and in that period rapidly expanding aerosol use caused a significant amount of cooling.  Various countries then passed clean air acts which reduced the levels of aerosols in the air.  (They also fixed a pretty major acid rain problem.)  In fact one of the proposed solutions for global warming is to deliberately inject aerosols in the stratosphere.<p>From these examples, it looks like your mind is made up.  You don&#x27;t even want to <i>find out</i> what the science says.  Instead you engage in a game of oversimplification and gotcha to convince yourself that what they are saying doesn&#x27;t make sense.
