Of course, the Sun is the ultimate cause of rising temperatures on Earth. The energy from the Sun is the driving force behind all the weather systems, ocean currents, wind storms and cloud activity.
But it’s the things you can’t see that are the most significant.
While Europe has been enjoying an early Summer, elsewhere in the world high air temperatures have been record-breaking.
