Climate Change Impact: Unusual Ice Floes and Antarctic Cleanup Efforts

The Argentine Navy discovered icebergs unusually close to Buenos Aires, possibly linked to global warming. Satellite images show pieces of the Ross Ice Shelf breaking off, expected to melt soon. British explorer Robert Swan's Mission Antarctica has been cleaning up the continent, collecting 1000 tonnes of rubbish. The cleanup has led to positive environmental impacts, with wildlife returning to rehabilitated areas. The initiative aims to inspire others to protect the environment.
