According to the information that I’ve found weather is becoming more extreme. With the amount of pollution that has been over boarding our planet the world atmosphere has fallen apart and has let more solar radiation to come in. This causes more thermal energy which effects the weather. With weather become more extreme the world is at a greater risk. **Are major storms ( such as hurricanes) becoming more frequent and more intense?** Yes, major storms are becoming more frequent and more intense. According to the information that I found Globally hurricanes are becoming more frequent. This is because of the increase of temperature. The average of hurricanes per year are 90, which is a huge jump compared to earlier times. (From 1850-1990 the average was 10-5 hurricanes per year. From 1998-2007 the average was 15 per year.)The strongest trends that have been recorded are in the North Atlantic ocean and Indian Ocean. The intensity of major storms have increased over the past 2-3 decades. The future of tropical storms will increase when weather varies outside the range of tolerance. The damages of more frequent and intense weather will increase damage disproportionately. Flood water will rise but little damage will be made but over a period of time it will cause an excessive amount of damage. All these effects will affect public safety and will cause great economic woes. **Are there more episodes of droughts and flooding around the world than there were in the past?** Droughts have effected our world for many years. According to the information that I have found droughts have been more frequent in some parts of the world. In the USA droughts have been becoming more frequent causing the US to become drier and drier. The cause for the increase of episodes of droughts is greenhouse gases. In Africa drought have always been a problem and has killed many people. It seems like in the past droughts have been more severe but in the present droughts have been coming more frequent. Floods are becoming more frequent because of climate change. In the years 1975-2001 the number of flash floods have increased. A**re the temperature extremes greater than they have been historically?**
 * topic 1 : Is weather becoming more frequent?**

Yes,temperature extremes are greater than they have been historically.This graph show the increase in temperature over the years. This is caused by global warming.
