Natural disasters are caused by something happening in nature, like a change n the weather. Sometimes we have warning of a natural disaster and other times they happen without notice. Earthquakes, tornadoes, floods, tsunamis, volcanoes, wildfires and winter storms are all examples of natural disasters. Learning about natural disasters can help us be prepared when they happen, and being prepared for natural disasters allows us to help ourselves and others during and after these challenging events! I made a timeline of the natural disasters I have researched in the next pages; Stronger Typhoons? * Effect of global warming on typhoon strength is currently the subject of intense scientific debate -Other ETC requirements: uniform winds along vertical, enough moisture throughout the troposphere -Not clear how global warming will change these * Skeptics: Observed rise in ETC strength due to (I) better observations, or (ii) natural variation * What is certain: Philippine populations are much more vulnerable to typhoons than before.
