AP Poll: Americans Increasingly Unconcerned about Climate Change

Those numbers obviously are not percentages so are they the actual number of people questioned. It is a very small sample if so.

In making the survey, the results depends up on the how the question is framed. In this the question is clear “global warming”. It is not so in many surveys. See for example:
Pro-global warming groups argue that “Overwhelming scientific consensus says human activity is primarily responsible for global climate change”. The 2010 Anderegg study found that 97-98% of climate researchers publishing most actively in their field agree that human activity is primarily responsible for “global climate change”. The study also found that the expertise of researchers unconvinced of “human-caused climate change” is “substantially below” that of researchers who agree that human activity is primarily responsible for climate change.
The 2013 Cook review of 11,944 peer-reviewed studies on climate change founded that only 78 studies (0.7%) explicitly rejected the position that humans are responsible for “global warming”. A separate review of 13,950 peer-reviewed studies on climate change found only 24 that rejected “human-caused global warming”.
A survey by German Scientists Bray and Von Storch found that 83.5% of climate scientists believe human activity is causing “most of recent global climate change”. A separate survey in 2011 also found that 84% of earth, space, atmospheric, oceann and hydrological scientists surveyed said that “human-induced global warming” is occurring.
More than one thousand scientists disagree that human activity is primarily responsible for “global climate change”. In 2010 Climate Depot released a report featuring more than 1,000 scientists, several of them former UN IPCC scientists, who disagreed that humans are primarily responsible for “global climate change”. The Cook review of 11,944 peer-reviewed studies found 66.4% of the studies had no stated position on “anthropogenic global warming”, and while 32.6% of the studies implied or stated that “humans are contributing to climate change”, only 65 papers (0.5%) explicitly stated “that humans are the primary cause of recent global warming.” A 2012 Purdue University survey found that 47% of climatologists challenge the idea that humans are primarily responsible for climate change and instead believe that climate change is caused by an equal combination of humans and the environment (37%), mostly by the environment (5%), or that there’s not enough information to say (5%). In 2014 a group of 15 scientists dismissed the US National Climate Assessment as a “masterpiece of marketing,” that was “grossly flawed,” and called the NCA’s assertion of human-caused climate change “NOT true.”

In the above presentation, there are several terms were used to imply human activity is responsible to: with several adjectives to global warming and climate change. They are:
• Global climate change
• Human-caused climate change
• Most recent global climate change
• Humans are contributing to climate change
• Global warming
• Human-induced global warming
• Humans are the primary cause of recent global warming
• Anthropogenic global warming
This clearly shows that there is an ambiguity on the terminology: global warming and climate change. This is also true with IPCC where they started using “global climate change” instead of global warming. IPCC is shy of using the word global warming.
Climate is function of several met parameters. When specific met parameter is used, they invariably use that parameter like global warming referring to only temperature. We can not use climate change for global warming.
In many cases climate change is used as de-facto global warming, an erroneous concept. IPCC or UN has never clarified this aspect even to date.
The other terminology is: human activity. There are several areas under this, namely, anthropogenic greenhouse gases influencing temperature through greenhouse effect, anthropogenic non-greenhouse effect [they are not really comes under human activity], non-greenhouse effect related cause through the destruction of nature, known as ecological changes by changing the land & water use and the land & water cover.
Ecological changes influence all meteorological parameters at local and or region level. They are not global in nature. They influence systematic variations at local and or regional level. Anthropogenic greenhouse gases influence temperature at global level through greenhouse effect. However, it is flawed argument as greenhouse effect is also a local and or regional factor. The global average of this is termed as “global warming”.
While making survey, the organizers must ask clearly “which human activity” and “is it climate change or global warming”? Otherwise the answers may become highly ambiguous and with little meaning.
