A "pre-attribution" study carried out prior to landfall estimated that, because of climate change, Florence’s most intense rains over North Carolina would be more than 50% heavier than they would have been otherwise. This is the type of behavior one might expect to see with global warming putting more moisture into the atmosphere and increasing the frequency and intensity of heavy precipitation events. rainfall events, when measured by how much rain fell over an area of 14,000 - 20,000 square miles over a 4-day period, have all occurred in the past three years-Hurricane Florence in the Carolinas in 2018, Hurricane Harvey in Texas/Louisiana in 2017, and a March 2016 storm in Louisiana. rainfall records for North Carolina and South Carolina. For the second year in a row, a very slow-moving hurricane smashed all-time record rainfall records in the U.S., as Hurricane Florence’s rains broke the U.S. Above: departure of Earth’s temperature from average between 1880 – 2018, for the year-to-date period of January - November. If an El Niño event develops and extends into early 2019, as predicted, it is likely that 2019 will end up even warmer than 2018. This means that the five warmest years on record globally will be the last five years-2014 through 2018. The year-to-date period of January – November ranks as the fourth warmest such period on record, and 2018 is a virtual lock to be the fourth-warmest year on record once the numbers from December come in. Here, then, is our pick of the top ten weather and climate events of 2018:ġ. Research published in October blamed “stuck” jet stream patterns like this on human-caused climate change, and predicted that our future climate is likely to bring a significant increase in such destructive jet stream patterns.
The high number of disasters was due, in part, to an unusually persistent and extreme summertime jet stream pattern that brought extended periods of extreme weather to parts of the Northern Hemisphere.
The only years with more were 20, which both had 41. This year’s preliminary tally of 37 billion-dollar weather disasters would be the third most on record, according to insurance broker Aon Benfield.

That’s the take-home message from 2018’s extraordinary series of extreme weather events-including at least 37 billion-dollar weather disasters-which demonstrated that dangerous climate change is not a distant future threat, but today’s reality.
