US weather whiplash shows climate change

A series of "once-in-a-millennium" rainstorms have lashed the United States in recent weeks, flooding areas baked dry by long-term droughts, as human-caused climate change brings weather whiplash.

And scientists warn that global warming means once-rare events are already much more likely, upending the models they have long used to predict possible disasters, with worse to come.

Lowest July Antarctic sea ice on record

Last month saw the lowest extent of Antarctic sea ice on record for July, according to the European Union's satellite monitoring group.

The Copernicus Climate Change Service (C3S) found Antarctic sea ice extent reached 15.3 million square kilometers - some 1.1 million km2, or seven percent, below the 1991-2020 average for July.
