The major concern is that melting could accelerate further beyond "tipping points" due to warming caused by humans - though it's not clear exactly how these mechanisms work, and where these thresholds sit."The strength of this study is that they use multiple lines of evidence to show that our climate is in a similar state to when several metres of ice was melted in the past," said Prof Andy Shepherd, a glaciologist at Northumbria University, who was not involved in the new publication.

"This would have devastating impacts on coastal communities," he added.An estimated 230 million people live within one metre of current high tide lines.Defining a "safe" limit of warming is inherently challenging, because some populations are more vulnerable than others.

But if sea-level rise reaches a centimetre a year or more by the end of the century - mainly because of ice melt and warming oceans - that could stretch even rich countries' abilities to cope, the researchers say."If you get to that level, then it becomes extremely challenging for any kind of adaptation strategies, and you're going to see massive land migration on scales that we've never witnessed [in modern civilisation]," argued Prof Bamber.

However, this bleak picture is not a reason to stop trying, they say.

"The more rapid the warming, you'll see more ice being lost [and] a higher rate of sea-level rise much more quickly," said Prof Stokes.The controls were put in place following concerns that chip technology with potential military uses could be deployed by companies loyal to China's communist party.

Mr Huang blasted the policies as a "failure" and said they were backfiring against American companies.on Wednesday that President Trump was ordering US chip software suppliers to stop selling their products to Chinese chip companies.

The move is intended to make it more difficult for China to develop its own advanced chips that would compete with Nvidia's, the paper said."The China export restrictions underscore the immediate pressure from geopolitical headwinds," according to Emarketer analyst Jacob Bourne.
