If I lift an object up in the air and let go of it, it will fall
Assuming controlled, equivalent conditions, it will always fall at the same speed, it will not fall upwards or stay in place or fall twice as fast
The Earth has been orbiting the Sun for billions of years, and the Sun has been fusing energy and warming us, and that's been pretty consistent too, though the exact details might be difficult to predict
Science is useful that way, once you have a model, you can make predictions, and once your predictions have been confirmed hundreds and thousands of time, you have something solid
What's the alternative? Stop driving cars because the laws of combustion might change and they might stop burning fuel from one moment to the next?
Not very useful, and not very likely either since it never happened
