My contention is not that the Climate has not Changed. Obviously, looking at rocks from hundreds of millions of years ago, it has.
My contrarian kicks in when those hundreds of millions of years of (sometimes severe) climate changes are considered, the human contribution is infinitesimal.
If Nature could do all that without human input, then just how minute must be the effects of human input, or the climate would have steadily warmed from the time we harnessed fire, not to mention burned off expanses of prairies to stampede animals over cliffs for sustenance and materials.
With no fire departments or water bombers to put out wildfires, they must have raged until they either ran out of fuel or storms extinguished them. How does that compare to modern output of whatever emissions are being blamed for changes in climate now? I don't know, but if the data is correct, the planet goes from horribly cold to livable in a series of cycles, and we are fortunate indeed to not live in one of the cold spells.
Where I live, some 12,000 years ago, there was an ice sheet over a kilometer thick. It turned the Missouri River South to find a new course and eventually link up with the Mississippi. I am glad it is gone, and frankly, its return would adversely affect my property values.
Be that as it may, winters are plenty cold, and despite the triple digit heat in summer, it parts with a "You're gonna miss me when I am gone" as the weather slips back into the frosty seasonal grip of single digit and subzero temperatures, something millions avoid by living farther south.
After all, the weather here is described as '8 months of winter and four months of hard sledding'.
If it's too hot where you live, move someplace cooler.
Mangoes don't grow here, nor peaches, pomegranates, bananas, paw-paws, and a wide variety of berries, fruits, and nuts that simply will not survive the winter. When we get those treats this far north, they were often picked green, shipped, and force ripened using ethylene when they arrived. The oranges you eat in Florida straight off the tree are incredibly different from what passes for an orange here. So, if their mangoes taste different this year, tell me, were they picked at the same stage of ripeness as last year's? Were they from the same trees? Same soil? A lot can affect the flavor and texture of fruit, and it isn't all the climate.
