climate change
A recent survey conducted by Weather Central and George Mason University makes this claim: TV Weathercasters' Views of Climate Change Appear to Be Rapidly Evolving

Meteorologists examine causes of weather change every day. They are the scientists most likely to understand when unusual weather extremes are weather or climate change. Thus they have been polled every year about climate change.

However most don't respond. Basically three fourths of weather scientists choose NOT to get entangled in a political, non-scientific debate. In 2015 the response rate was 22%, just 32% in 2016 and in 2017 just 22%. And as true for most skeptics, most agreed climate change is happening. However the question is: What is the cause of that change?

Of 2017's respondents, only 15% thought climate change was entirely due to humans, while 34% thought 60 to 80% could be attributed to human activity. However the survey did not separate human contributions to climate change from urbanization, deforestation, loss of wetlands or CO2 .

One fifth, or 21% thought changes were mostly or entirely natural while 8% admitted they just didn't know.

So for ALL meteorologists surveyed only 11% actually claimed humans were mostly responsible for observed climate change: 22%(response) X 49% (attribution).

The survey was done by advocates of CO2 warming at ClimateCentral. Read it here:
