I believe that we are contributing to climate change but charts like these are garbage and in my opinion contribute to empowering denialists. The lines on the first two charts were placed arbitrarily, a linear regression on those might in fact slant downwards. The data was cherry picked as well. The third chart us of a metropolitan area that has sprawled over the past 140 years shown, of course the average temperature should be higher as metro areas are giant heat sinks. (id be curious to know how much this is contributing but don't dare say cities are bad for the environment). If you have to try selling something by manipulating data then it raises questions.
All that said we need to stop trying as hard to curb climate change and C)2 emmisions and instead start preparing for the consequences. This is because there is a real chance that either we cant stop the trend or the trend isn't man made. In wither case we will be better served by being ready. And while warming is bad, coming up with some sort of crazy aerosol/solar shield etc cooling plan that sends this earth back to a snowglobe is much much worse.
