Summers Stretch: Global Cities Feel The Heat

Global summers are extending, arriving earlier, and lasting longer due to accelerating climate change, according to new research. A study analyzing ten global cities found that summer conditions are increasing by an average of six days per decade.

In Sydney, Australia, the summer period has nearly doubled in length since the 1960s. While historically starting in January, recent summers now commence as early as November, extending well into March. This intensification is attributed to human-induced global heating.
