An ice age is a long interval of time (millions to tens of millions of years) when global temperatures are relatively cold and large areas of the Earth are covered by continental ice sheets and alpine glaciers. Within an ice age are multiple shorter-term periods of warmer temperatures when glaciers retreat (called interglacials or interglacial cycles) and colder temperatures when glaciers advance (called glacials or glacial cycles).
Currently, we are in a warm interglacial that began about 11,000 years ago. The last period of glaciation, which is often informally called the “Ice Age,” peaked about 20,000 years ago. At that time, the world was on average probably about 10°F (5°C) colder than today, and locally as much as 40°F (22°C) colder.

Maybe global climate fluctuation
Is this helping?
Both Terms Have Long Been Used
The argument "they changed the name" suggests that the term 'global warming' was previously the norm, and the widespread use of the term 'climate change' is now. However, this is simply untrue. For example, a seminal climate science work is Gilbert Plass' 1956 study 'The Carbon Dioxide Theory of Climatic Change' (which coincidentally estimated the climate sensitivity to a doubling of atmospheric carbon dioxide at 3.6°C, not far off from today's widely accepted most likely value of 3°C). Barrett and Gast published a letter in Science in 1971 entitled simply 'Climate Change'. The journal 'Climatic Change' was created in 1977 (and is still published today). The IPCC was formed in 1988, and of course the 'CC' is 'climate change', not 'global warming'. There are many, many other examples of the use of the term 'climate change' many decades ago. There is nothing new whatsoever about the usage of the term
In fact, according to Google Books, the usage of both terms in books published in the United States has increased at similar rates over the past 40 years:

I keep reading on non main stream media news sites that the mean earth temperature has not risen for the last sixteen years,
Antarctic sea ice is the most its ever been (since records began)
The sphinx had a coating of snow this year, a town in New Zealand had snow for the first time in seventy five years, various glaciers are growing again, um, perhaps the world is only warming up where volcanoes are?
