Climate records tumble, leaving Earth in uncharted territory - scientists

A series of climate records on temperature, ocean heat, and Antarctic sea ice have alarmed some scientists who say their speed and timing is unprecedented.

Dangerous heatwaves in Europe could break further records, the UN says.

It is hard to immediately link these events to climate change because weather - and oceans - are so complex.

Studies are under way, but scientists already fear some worst-case scenarios are unfolding.
