El Niño triggers extreme weather patterns.

El Niño, a natural climate phenomenon marked by warmer ocean temperatures in the equatorial Pacific, has officially begun. It exacerbates the effects of climate change, causing hotter weather and temperature records. El Niño also brings drier, warmer weather to the Northern US and Canada, exacerbating wildfires and drought. In the Southern US, it adds even more juice to dangerously heavy rain storms, causing flash floods. However, El Niño is not good for Atlantic hurricanes, but human-caused climate change is making warm water help hurricanes grow, resulting in a slightly above-average number of storms this year.
