I promised myself to withdraw from this thread. But your argument just got delusional on a whole new level.
Firstly: you're wrong about the ice melting. Look up the respective densities of ice and water - they're almost identical (there's only a difference in the fourth significant figure). They can practically be considered the same. What this shows is that when the part of ice that's above water melts, the surface of the water will rise. Again, do the experiment, record the data, prove me wrong if you want to. As it stands, I've provided accurate data and you've given nothing so on that basis, I win this point. I won't do the hard work for you and prove myself wrong.
Some fields in science are more advanced than others - some are still developing. Biologists clearly don't know about every living animal of every species. Saying that a certain animal is probably extinct is on the basis of educated guesswork, not actual experiments, formulas and so on.
Scientists have always gotten things wrong here and there and will continue to get things wrong. Newton, as right as he was, was proven wrong by Einstein on all fronts. Does this mean that Newton did not contribute to science? Certainly not. His equations and laws were just one step towards an accurate understanding of the world. The remarkable accuracy with which this is done today is a testament to the success of science.
Furthermore, Stephen Hawking says in A Brief History of Time - You can never prove a theory right, it can only stand the test of experiment and if it predicts the outcome of experiments accurately, then it's a good theory. However, you can prove a theory wrong.
Just because you cannot prove a theory right, does that mean science is useless? Hell no. Look at where it's gotten us.
If scientists tell you that continuing to do a certain activity is likely to cause the eventual destruction of our species, you should listen to them until someone actually proves them wrong because that's not something that should be gambled with.
This is the last thing I will post in this thread, directed at BlueFlame anyway, until he proves me wrong about ice melting and rising the surface of water.
