So, about +0.11 °F/decade (+0.06 °C/decade) over 130 years. The Little Ice Age went from 1300 to 1850, so we were just coming out of the Little Ice Age in 1895. We are expected to increase in temperature and this is a good thing. The Little Ice Age was a time of famine and unrest. In the next 500 years we will enter another cold period and that will be a problem.
Interesting to note that most of the increase appear to be before 1935, before we started to massively increase CO2 emissions. Another degree of warming and another 150 ppm of CO2 would move us to the sweet spot where temperature related deaths would be minimised and crop yields would increase. Keep up the good work.
