You cannot show a climate model with and without the effects of man give the sea level rise happening now, because you don’t even know what that is....

Climate models are incapable of predicting the temperature pause that has occurred over about the last 20 years in the troposphere. They are incapable of predicting the ocean temperature oscillations - they have to be an input into the model. Have a look at the global warming policy foundation.

The science is so far from settled, it’s at a very basic level.
Science is a matter of probabilities rather than 100% certainty. So when scientists say they "know" something, they are saying "it is extremely likely".

Scientists know climate change is happening. They know there is a general trend towards warmer temperatures. They know that various greenhouse gases increase temperatures and that the prevalence of these in the atmosphere is increasing.

Now, climate change models are extraordinarily complex. The only way to make such a model 100% correct is to build another Earth, so that's unlikely to happen anytime soon. The lack of such a model doesn't make today's models wrong: it just makes them less certain. If anyone wishes to deride them, they need to come up with a better model that fits the facts and is logical.

There is no reasonable doubt that man-made climate change is is occurring and that, left unchecked, it will have catastrophic consequences for humanity.

Furthermore, there is a lot that most people can do to reduce emissions of greenhouse gases. Eat less meat. Walk instead of using a car for short journeys. When you drive, drive economically. Buy a fuel-efficient car, or an electric one. Where feasible, buy locally produced goods.

And, yes, take fewer plane trips.
