Of course we are in a warming trend. The question is how much is contributed by human activity, and how much is part of  cycling.  Perhaps the best correlation is with population growth  and standard of living. That's a difficult one to reverse. Most of your numbers are out of date. They have since been reduced  by the essentially flat line for about the last 20 years. That messed up a lot of those 'scientific' temperature projections of the 90's. There are pluses and minuses. Agricultural production should be increasing. Actually I like somewhat warmer winters where I live. Cold is actually a greater health risk than warmth. Cold--an underrated risk factor for health. - NCBI https://www.ncbi.nlm.nih.gov/pubmed/12706750 There are those that argue that the human contribution might have altered the cooling trend from the Little Ice Age.  Anyway, rational and cost effective approaches to greater less waste, energy efficiency and sustainable and reliable non fossil fuel energy (when feasible) are always  good things.
