Document Summary
Test hypothesis using more and more observations, and they will either suggest that the hypothesis is correct, or that a new one is needed. Theory is developed from the successful hypotheses. As long as all the tests pass, you can make predictions of the end-result. After very long and always successful testing of the theory, it will be reworded into law. We can"t control natural hazards, we simply work at predicting them and reducing their efforts: assessing risk, looking at precursor signs. Natural disaster: a sudden misfortune/ calamity local scale. China, city of tanshan, 1976: earthquake, regional catastrophe. The rising cost of natural disasters and catastrophes. Global climate models predict that a warmer climate will lead to higher sea levels, coastal flooding, more intense storms, heat waves etc. Earth"s climate has always changed, but recently humans have been forcing some of that change.
