What is it that I am not paying attention to.
Where do you get your assertion that nobody is saying climate change is a natural event.
The article written by Oreskes, a supporter of anthropogenic climate change, included an analysis of 928 papers containing the keywords “global climate change” whether or not they were by climatologists or even about climate change. Of those about 25% admitted to believing there was human caused climate change. About 50% agreed there was climate change by natural causes. And the rest expressed no opinion on whether climate change was anthropogenic or not. But understand that the survey was of scientists from all branches of science. If you eliminate all who are NOT climatologists, meteorologists, or geologists; the consensus narrows even further. In fact geologists, the science which covers climate over the long term; are far less supportive of anthropogenic climate change. They see the cycles of warming and cooling and how they compare before and after the industrial revolution.
Almost all more recent estimates of science consensus on climate change base their figures on Oreskes' article. Of those which have done their own surveys, most of the questions do not address the question of whether climate change is anthropogenic. Instead the questions are often about whether the public BELIEVES there is human caused climate change. This is misleading. Another misleading detail is that most science papers on climate change do not address the cause but rather address the problems caused by climate change (regardless of whether the cause is natural or man made. In fact The in 2013, U.S. President Barack Obama sent out a tweet claiming 97 per cent of climate experts believe global warming is “real, man-made and dangerous.” As it turns out, the survey he was referring to didn’t ask that question.
The Intergovernmental Panel on Climate Change asserts the conclusion that most (more than 50 per cent) of the post-1950 global warming is due to human activity, chiefly greenhouse gas emissions and land use change. But it does not survey its own contributors, let alone anyone else, so we do not know how many experts agree with it. And the statement, even if true, does not imply that we face a crisis requiring massive restructuring of the worldwide economy. In fact, it is consistent with the view that the benefits of fossil fuel use greatly outweigh the climate-related costs.
In 2012 the American Meteorological Society (AMS) surveyed its 7,000 members, receiving 1,862 responses. Of those, only 52% said they think global warming over the 20th century has happened and is mostly man-made (the IPCC position). The remaining 48% either think it happened but natural causes explain at least half of it, or it didn’t happen, or they don’t know.
The Netherlands Environmental Agency recently published a survey of international climate experts. 6550 questionnaires were sent out, and 1868 responses were received, a similar sample and response rate to the AMS survey. In this case the questions referred only to the post-1950 period. 66% agreed with the IPCC that global warming has happened and humans are mostly responsible. The rest either don’t know or think human influence was not dominant. But this Dutch survey is even more interesting because of the questions it raises about the level of knowledge of the respondents. Although all were described as “climate experts,” a large fraction only work in connected fields such as policy analysis, health and engineering, and may not follow the primary physical science literature.
Regarding the recent slowdown in warming, here is what the IPCC said: “The observed global mean surface temperature (GMST) has shown a much smaller increasing linear trend over the past 15 years than over the past 30 to 60 years.” Yet 46 per cent of the Dutch survey respondents - nearly half - believe the warming trend has stayed the same or increased. And only 25 per cent agreed that global warming has been less than projected over the past 15 to 20 years, even though the IPCC reported that 111 out of 114 model projections overestimated warming since 1998.
Another point to consider is how often is the majority correct? In the early to mid 20th century, the majority of scientists were on board that our planet was getting cooler, or about to get cooler and an ice age was on the way. The majority of the mid 20th century scientists had a very convincing sounding theory on air pollution reflecting solar rays and causing cooling. The consensus on the cause of lunar craters use to be volcanic activity. And the consensus on plate techtonics was the same figure quoted for climate change of 97%. But the 97% were OPPOSED to the idea of plate techtonics!
