People in general don't know about the temperature variations the earth has experienced in the past. For example, did you know that the Vikings established dairy farms in Greenland a thousand years ago or so? We can still see them ... under the ice.
Did you know that the Thames River in London and the Zuyder Zee in Holland used to freeze over in the period known as the "Little Ice Age" during the 17th-19th centuries. The Hudson River in New York used to freeze solid in the 18th century. Good thing, too, or Washington would have had a hell of a time getting his cannons across the river during the Revolutionary War.
If you think that anthro-centric global warming has increased the number and ferocity of hurricanes (as Robert Kennedy, Jr., does) I think you can put your mind at rest. The National Oceanic and Atmospheric Administration (NOAA) has issued a report denying that possibility:
NOAA research shows that the tropical multi-decadal signal is causing the increased Atlantic hurricane activity since 1995, and is not related to greenhouse warming.
So cease your ceaseless hand-wringing!
