Written by scientist that study climate changes.
This is credible because the facts are backed up by charts and graphs on the recent weather.
They say that Global Warming is warming the seas and causing more severe Hurricanes.
I believe this because I have seen hurricanes get stronger and deadlier every year such as Hurricane Katrina.

This is credible because the source is based on years of researching changes in the level of hurricanes recorded.
They say that most Hurricanes in the future are likely to be above normal due to the warming of the seas.
I believe this source because they back up their facts by charts showing years of research.

Based on research by scientist that study climate changes on Earth.
This is credible because it is published by USAToday and the source is based on scientist.
They say that due to the effects of Global Warming the weather such as hurricanes are getting more severe every year.
I believe this because the rest of the sources say this and I have seen the changes myself.

I believe the weather is changing every year due to Global Warming. I have seen the Hurricanes in the Atlantic get more severe every year.
