One universal characteristic of people, even highly educated individuals, is that we tend to prefer simple and uncomplicated answers, even to problems that are anything but simple.
That’s one of the reasons why getting people to understand the danger of global warming and climate change is so difficult, and when you add in the problem that the effects of what world industries and what billions of people choose to do today won’t fully impact the world ecosphere for years, if not for decades or generations, the difficulty becomes much greater.
The heat waves the U.S. is experiencing right now are the result of “normal” summer weather patterns boosted by years of underlying incremental changes, and these changes have impacts in all sorts of interlocking changes. There have been literally thousands of studies confirming these effects, and essentially no reputable ones refuting the overall trend, yet people see all those numbers and throw up their hands.
The article here [ https://www.tomorrow.io/weather/blog/global-warming-status/] [brought to my attention by a reader] presents those interactions without presenting the myriad of numbers and calculations behind the descriptive analysis. But the numbers do exist, supported by thousands of studies over years. Despite claims to the contrary, there’s no reputable evidence against global warming or against the human contribution to it.
Yet, accurate as I believe the article to be in general terms, there are always outliers that climate deniers will cite, using hard numbers for a specific instance. For example, the vast majority of glaciers in the world are shrinking, but there are a handful that are increasing. Antarctic ice shelves are crumbling in overall extent, but inland build-up of Antarctic ice is increasing in some areas because warmer ocean air around the Antarctic holds more moisture that turns to snow in colder areas.
People also rely more on personal experience and anecdotal evidence than on statistics. But anecdotal evidence and experience only persist as long as individuals live. I can personally testify how the importation and stockpiling of massive quantities of water by the Denver Water Board fueled runaway growth in the Denver Metro area, with a resulting local micro-climate that is far more humid than the dusty plains where I grew up [which are now damper and hotter wall-to-wall suburban houses]. But there are fewer and fewer of us who can testify to those times, and if there’s no one left to relay those stories and you don’t trust statistics and records, the actual facts get ignored… or ignored even more.
