A common space for harmonic peacemakers
Scientists are warning of dramatic changes at one of the biggest glaciers in Antarctica, potentially within the next five to 10 years.
They say a floating section at the front of Thwaites Glacier, that until now has been relatively stable, could "shatter like a car windscreen".
Already it is dumping 50 billion tonnes of ice into the ocean each year.
Meanwhile, in Siberia, the highest temperature ever recorded in the Arctic - 38C (100F) - has been officially confirmed, sounding "alarm bells" over Earth's changing climate.
