Those who claim scientists are wrong about global warming use the recent not-so-warming trend to deny climate change. I want to point out that weather prediction (closely related to climate-change prediction) has never been an exact science. Whenever I listen to a weather report, then stick my head out the window seeing the exact opposite, I know how fallible weather prediction can be. All the satellites and computer models in use today have not allowed for perfect weather prediction: Chaos theory dictates that truth. The butterfly effect, or the unpredictability of a single butterfly sneeze in the Arctic on global weather patterns, has not been overcome.
Climate-change deniers can remain skeptical while global CO2 builds up. Science knows greenhouse gases hold in heat; how it plays out in our atmosphere globally is the only question. Denial is asymptom of addiction in this case, it is fossil-fueled greed.
We were not around the last time our planet experienced a rapid temperature increase. Nobody denies its results: The dinosaurs were wiped out.
