Hello A and welcome to this section of Answers, good that you’re bringing more intellectual ability to the debate.
You’ve raised a lot of issues there, I’ll go through some and give my perspective…
<< How could scientists present evidence for anthropogenic global warming in a way that convinces those who resist the very concept of man-made environmental problems? >>
I guess people fall into six generic categories when it comes to anthropogenic global warming (AGW):
• Outright believers simply accept it’s happening without question.
• Skeptical believers accept it’s happening but question the hows and whys.
• The undecided are open to persuasion either way.
• Skeptics generally go against the AGW theory but are responsive to evidence.
• Deniers simply deny it’s happening irrespective of anything.
• And the unaware don’t know about it, or not enough to make a decision.
An exchange of ideas is possible with all but the deniers, as such it is a pointless exercise trying to educate them as they are not willing to learn and will unconditionally reject anything that goes against their preconceived notions. This is a characteristic that is observed in several regulars on Answers as I’m sure you’re already aware.
Take for example the claim that volcanoes dwarf humanity’s contribution to global warming. 306 questions have been asked in this section concerning volcanoes and in total the claim must have been refuted at least 1000 times. Here is just one such example from earlier today https://answersrip.com/question/index?qid=20100701012546AAH8ODo&show=7#profile-info-Aqe0hGCIaa and the full list of volcano questions http://answers.yahoo.com/search/search_result;_ylt=AqFu8A4d7sEFWxHj.7NmaaMjzKIX;_ylv=3?scope=all&exclude_terms=&category=2115500306&fltr=_en&question_status=all&date_submitted=all&crumb=lIKL9JIg09D&p=volcanoes&keywords_filter=all&filter_search=+Apply
Despite the fact that the deniers make such a claim they have never provided any evidence to support it. Given the number of time’s it’s been conclusively proven to be a fallacy you would think that any sensible person would have got the message. Not so the deniers who I guarantee will keep on making this same old claim again and again and again.
<< Do "skeptics" understand that the science will never be that simple because the climate is too complex? >>
No, they have managed to convince themselves that they are sufficiently well versed in the subject of climatology to arrive at informed conclusions. In reality nothing could be further from the truth and this is witnessed in the astonishing number of errors they make at even the most fundamental level. Many of them can’t even distinguish between weather and climate.
The true skeptics, and this includes all scientists, will continue to question the issue of climate change as this is one of the best ways of expanding our comprehension of a staggeringly complex subject and greatly enhances our understanding.
<< how can scientists convince Fox News junkies that a looming problem, with worst-case scenarios decades away, is something to be concerned about right now? >>
The issue of climate change needs to be kept in context. The ‘worst-case scenarios’ are unlikely to happen and often what’s depicted in the media isn’t actually representative of the scientific findings. It doesn’t help when the media are reporting runaway global warming, inundation of coastal cities, rapidly rising temperatures and portraying these in a sensationalistic manner implying such event could happen quickly with little warning.
You’re quite right that this is an issue that we need to be concerned about. Unless we physically intervene with the climates of Earth then we have already released enough greenhouse gases into the atmosphere to affect the climate for the next 85 years. This is a situation that can only possibly get worse the longer we delay taking real action.
Personally I don’t think we need to convince the Fox News junkies. They are very vocal but are small in number. It’s at governmental levels where policies are going to be implemented and change brought about.
<< With older "hoaxes" like man-made ozone depletion and acid rain, it was relatively easy to fix the problem with technology (newer refrigerants and smokestack scrubbers). >>
Global warming is the fourth instance of human activities having a potentially disastrous effect upon the climate. In all previous cases the scientists accurately identified the problem, diagnosed it and proposed the solutions. Action was taken and the problems were averted or significantly reduced.
In each instance the authorities simply got on with it and did what was needed to resolve the issue. If they would do the same with climate change the problem could be addressed.
However, one major difference is that the solutions to the climate change issue are much more far reaching, they’re infinitely more costly and without the implementation of a geoengineering scheme it means we’re all going to have to admit to being a part of the problem and will have to make adaptations. And many people don’t like this notion, they would much prefer to continue as they always have.
Instead of facing up to the problem, some people are taking the easy way out by pretending the problem doesn’t exist. This enables them to absolve themselves of all responsibilities and ignore the consequences of their actions.
<< It seems there would have to be a single event, like thousands of dead Americans from a single heat-wave, to thaw conservative minds. >>
I don’t think that would be enough to convince many people, especially not the deniers. In 2003 a heatwave in Europe killed in excess of 30,000 people and this is just one instance of a rapidly increasing number of heatwaves. Whilst it may have convinced some people it did little to change the mindset of the deniers.
<< What EXACTLY is needed to convince you of the validity of slow-moving environmental dangers? Simpler language? Larger fonts? Drowned corpses in your own front yard? What will it take? >>
More than anything it will take time. The number of deniers and skeptics is diminishing all the time, in years to come there will be virtually none left.
It’s very similar to when the dangers of smoking were first announced. For decades there were people who denied that smoking was harmless and in the end it’s now more or less universally accepted as a hazard. Many of the arguments used by the tobacco deniers are exactly the same ones being used by today’s climate change deniers
In summing up I’d suggest that the deniers are of little consequence. They’re a closed group, small in number and are more concerned about convincing themselves that climate change isn’t happening than anything else.
