Summer 2021: A Hotter Than Normal Start.

Parts of Europe, Asia, and North America are already experiencing a heat wave, with temperatures expected to spike in the coming weeks as the world's oceans hit record-high sea surface temperatures. The return of an El Niño climate pattern is raising fears about more heat waves and droughts around the world, along with potential "major disruptions" to marine ecosystems. Climate change is expected to make heat waves more likely and intense, increasing the risk of wildfires, droughts, and heat-related illnesses and deaths globally.
