But even keeping to 1.5C would still lead to continued melting of Greenland and Antarctica, as temperature changes can take centuries to have their full impact on such large masses of ice, the researchers say."Our key message is that limiting warming to 1.5C would be a major achievement - it should absolutely be our target - but in no sense will it slow or stop sea-level rise and melting ice sheets," said lead author Prof Chris Stokes, a glaciologist at Durham University.

saw the world's nations agree to keep global temperature rises "well below" 2C - and ideally 1.5C.That has often been oversimplified to mean 1.5C is "safe", something glaciologists have cautioned against for years.The authors of the new paper, published in the journal

, draw together three main strands of evidence to underline this case.First, records of the Earth's distant past suggest significant melting – with sea levels several metres higher than present - during previous similarly warm periods, such as 125,000 years ago.

And the last time there was as much planet-warming carbon dioxide in the atmosphere as today - about 3 million years ago - sea levels were about 10-20m higher.

Second, current observations already show an increasing rate of melting, albeit with variation from year to year.According to the Wall Street Journal, Apple chief executive Tim Cook called Governor Abbott earlier this month in a bid to stop the passage of the state's bill.

An Apple spokesperson said the tech giant shares "the goal of strengthening kids' online safety" but added it was "deeply concerned" by the threat it believes the law poses to the privacy of all users."[I]t requires app marketplaces to collect and keep sensitive personal identifying information for every Texan who wants to download an app, even if it's an app that simply provides weather updates or sports scores," the company spokesperson said.

In February, Apple announced a slew of new child safety measures, including a requirement that users select an age range on a new device.For users under 13, a parent or guardian must provide consent for a child to use the ‌App Store‌ and other features that require the use of its Face ID.
