Except for the willfully ignorant, it is obvious that predictions ARE playing out. Record setting massive hurricanes and typhoons are happening every year now. 500 and 1000 year floods and storms are occurring every couple of years The antarctic had temps as high as temps in San Diego last week. The arctic ocean ice is thinner than ever measured, with a steady decrease in average area covered.Glacier National Park has only 18% of the glacial coverage it has had for 10,000 years. They think that just because the earth has had temp swing in the past, that it won't be a problem now. They think that spending a few trillion now to get off carbon is stupid , because we aren't 100% certain it will save 100s of trillions in the future
For the stupid, an average decrease in area covered doesn't mean that every year the area will decrease, but over time, the average area covered by ice is shrinking . The climate change deniers have no clue as to how a greenhouse works, or what a tipping point is. They don't understand that the ocean is a massive heat sink that is slowly warming while the planet absorbs more and more solar heat. And now that ocean temps have risen, the air is warming, and the oceans will continue to absorb most of the heat, but oceans drive the weather, and the ignorant just don't understand.They believe everything will be fine, because after all, the plant was warm in the past. But they ignore that the greenhouse gases at the level they are now have never existed since the dawn of man.
And just because some of the most dire predictions from outliers in the science haven't happened as predicted, the believe that they can claim none of the predictions have happened. And the stupidest say that because there is disagreement over how fast changes will occur, or how serious the changes will be, or how long we have to make changes to slow the increase, that none of it is true.
