Planet Earth is heating up at an unprecedented rated, and natural disasters is just one by-product of rapidly rising temperatures. Floods in particular will become yet even more commonplace as sea levels rise as a result of the melting of sea ice. Superstorms such as hurricanes and tornadoes will continue to become stronger and more violent.
Natural disasters are getting worse due to global warming. The frequency and intensity has increased, coinciding with higher temperatures. Former 100 year old storms are occurring every couple of years. For instance, Superstorm Sandy hit a year or two after Hurricane Irene. We know global warming has this type of affect.
No, I do not feel that natural disasters are getting worse because of Global Warming. It is fair to say that the term "natural disaster" implies unpredictability and massive loss of life a property. Natural disasters will always have harsh effects, and that makes the use of the word "worse" a subjective term. Early predictions of the effects of Global Warming have already been disproven. In addition to this fact there is not enough historical data to prove that Global Warming truly exists.
Depending on who you ask global warming is either something that is destroying our planet or it is something that does not exist. Global warming is something that is entirely present on our planet, however natural disasters are getting worse due to the natural progression of nature on this planet. A look back at history will show destruction by volcanoes, massive worldwide earthquakes, a worldwide flood, and several ice ages. Global warming is simply a side effect of the natural process of life on the planet earth.
