there is any disturbance in the climatic factor Temperature , precipitation , gaseous ratio in the atmosphere i.e increasing temperature ,carbon-dioxide and other pollutants some times alter the situation which may harmful for the living being. so this is altered state of the climate due to any reason i.e anthropogenic and natural leads to climate change. if you know more about please follow this link http://www.sciencedirect.com/science/article/pii/S0959378003000633 i think it may help you
According to IPCC Glossary-
Climate change refers to any change in climate over time, whether due to natural variability or as a result of human activity. This usage differs from that in the United Nations Framework Convention on Climate Change (UNFCCC), which defines ‘climate change’ as: ‘a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods’, where-
Climate in a narrow sense is usually defined as the ‘average weather’, or more rigorously, as the statistical description interms of the mean and variability of relevant quantities over a period of time ranging from months to thousands or millions of years. These quantities are most often surface variables such as temperature, precipitation, and wind. Climate in a wider sense is the state, including a statistical description, of the climate system. The classical period of time is 30 years, as defined by the World Meteorological Organization (WMO).
Science requires that a student first learns the basic things from textbooks himself and then asks questions. And, as mentioned, nowadays there is Wikipedia free for all. Then when you have specific questions you ask those.
I have writen and documented and detailed described that, and discovered the mechanisms involved

well people used to use the term agw and they changed it recently to climate change, but in fact it is natural variability, read my findings they should help you deepen into the subject
neither the animal extinction around anthroponet, but better refer to my findings than ask questions
... that is almost nothing but increasing the global temperature steadily!

The UHI effect is accounted for in GLOBAL temperature increase and constitutes a negligible contribution
And climate is not weather: global warming means warming over climate periods. And climate means that such a period is taken in which variations in weather are minimal compared to the average. That means in practice a period of at least 30 years. And temperature change is that of a period of 30 years at least versus that of a period prior to that of a least 30 years.

Even in case a period of twenty years is acceptable (to IPCC perhaps) then a change within this period is not of climate relevance. Thus compare 1996-2015 to the 20 year period 1975-1994. But as you know better than I do that it might be fortuitous that this does not span the same number of el-ninos; for that reason the longer the period the better the averaging over that pheoemenon

The clipping looks like it Is from a PR statement and not worthy to be seriously discussed. The fact that he provides an "absolute" temperature is already evidence
