The best answer to most of the claims by climate activists and their political allies is simply: so what?
“Climate change is real,” they say. So what? Gravity and sunrise are also real. That doesn’t mean we cause them or we would be better off without them. Climate has been changing since the origin of the atmosphere billions of years ago.
But, “manmade climate change is a fact,” they respond. So what? It is obviously warmer in urban areas than in the countryside because of manmade impacts. But the only place where carbon dioxide (CO2) increase causes a temperature increase is in computer models preprogrammed to show exactly that. All records show that temperature increase precedes CO2 increase.
All that should matter to public officials is whether our CO2 emissions are in any way dangerous. Since they are almost certainly not, the $1 billion spent every day across the world on climate finance is mostly wasted.
But, they tell us, “2014 was the hottest year on record, until 2015 surpassed even that. The last two decades include the 19 hottest years on record.”
So what? 2014 set the record by seven hundredths of a degree Fahrenheit; 2015 by 29 hundredths of a degree. These amounts are too small to even notice and one is even less than the government’s uncertainty estimates of 14 hundredths of a degree.
Regardless, one would naturally expect the warmest years to be at the top of a warming record. And thank goodness we have been in a gradual warming trend since the depths of the Little Ice Age in the late 1600s.
But “observations of extreme weather events are increasing. Insurance claims are skyrocketing,” we are told.
So what? As human habitation increases in areas that were previously sparsely populated, there will naturally be more reports of extreme weather and more related insurance claims. The database of the State Climate Extremes Committee clearly shows that the incidence of state-wide extreme weather records has been decreasing in recent years.
The next alarmist claim? “Sea levels rose 7 inches in the last century!”
So what? Sea level has been rising since the end of the last glacial period, 15,000 years ago. There has been no recent acceleration, and the current rate of rise is less than one tenth that of 8,000 years ago.
As their climate change claims fail, activists change targets: “The oceans are becoming more acidic and a catastrophe awaits if this continues!”
Overall, the oceans have never been acidic (i.e., a pH less than 7). Dr. Craig Idso, founder of the Center for the Study of Carbon Dioxide and Global Change explains: “Forecasts of future pH come from unproven, theoretical postulations by models based on absorption of CO2 by the oceans. Regardless, there really is no such thing as a representative pH for the whole ocean. It varies vastly near the coast and in upwelling regions, much more than the projected increase in acidity.”
