//__ Topic 1: Is weather becoming more extreme? __// Ø ** Are major storms (such as hurricanes) becoming more frequent and more intense? **  Storms (such as hurricanes) are becoming more intense because of global warming. How does global warming cause hurricanes to happen? Global warming causes the oceans to become warmer which make the atmosphere have more moisture, so the amount of rain the hurricanes produce will eventually increase. Scientists have also found some evidence that global warming has been increasing the intensity of hurricanes over the past decades, which means that the hurricanes are becoming more intense. Hurricanes come most likely every single year. Scientists say that the average hurricanes that happen per year are 90. Ø ** Are there more episodes of droughts and flooding around the world than there were in the past? **

A lot of droughts and flooding around the world have been affecting many people, like in Africa. People in Africa have been struggling with droughts since 1900-2009. There are more episodes of droughts and flooding around the world now than before because of global warming, and flooding and droughts nowadays are more severe than ever because of how people change and made their landscape. Ø ** Are temperature extremes greater than they have been historically? ** Yes, temperature extremes are greater than they have been historically because of  Global warming. The graph below shows how the annual temperature increased in a five year average in the past since 1880-2000.
