In a world growing increasingly accustomed to wild weather swings, the last few days and weeks have seemingly taken those environmental extremes to a new level.

When the world is warmer, it is likely to have more extreme weather and climate events, including record heat and rainfall, scientists say. And climate change is also changing weather patterns, leading to rainy and hot systems stalling over areas and the jet stream meandering, said Alvaro Silva, a climate scientist at the World Meteorological Organization.
