> Climate change is true not because of a lack of challengers.

In fact, the opposite is true. The theory that the rising atmospheric carbon level is causing a rise in average global temperatures has had many competing theories going back decades. None have been nearly as consistent with the observations as this theory.

Likewise the theory that the rise in atmospheric carbon is due to human activity has had many challengers, but none have explained the observations as well.

What will come of rising temperatures is a matter of less agreement, and less certainty. Rising water levels in the back yards of most humans is a common worry among scientists, but the current situation is rather unique, so nobody really knows what will happen, much less what the timeline will be. However, temperature deviations of the magnitude we are currently in have drastically altered global climate in earth's history.
