Models of Climate Change and weather forcasts are equally wrong, most often.
What does subways have to do with climate change? Even though the idea of subways was to allow freedom of movement at all times, it is still a idea or vision for the subway and that does not mean it works in practice. Putting the subways aside; no it is not always that the weather forecasts are exact, but they are very often right. When we see a weather forecast, you are right that they are not 100% right, but there is a good reason for that. When you have to forecast the weather, you look at the different pressures in the different areas and thereby predicting e.g. a storms movement a behaviour. So when you see a weather forecast, it is 100% right if nothing in the pressure changed since it was made. Climate change and weather forecast are scientifically proved. Since we can measure the amount of carbon-dioxide in the atmosphere which is 0.06%, while it was 0.05% 50 years ago. That's an increase on 20% which is obvious with the boom in the oil industry.
