The tech firms face new regulations.

1% of people cause half of global aviation emissions – study
Exclusive: Researchers say Covid-19 hiatus is moment to tackle elite ‘super emitters’
Frequent-flying “‘super emitters” who represent just 1% of the world’s population caused half of aviation’s carbon emissions in 2018, according to a study.
Airlines produced a billion tonnes of CO2 and benefited from a $100bn (£75bn) subsidy by not paying for the climate damage they caused, the researchers estimated. The analysis draws together data to give the clearest global picture of the impact of frequent fliers.
Only 11% of the world’s population took a flight in 2018 and 4% flew abroad. US air passengers have by far the biggest carbon footprint among rich countries. Its aviation emissions are bigger than the next 10 countries combined, including the UK, Japan, Germany and Australia, the study reports.
Iran and US on collision course in Trump’s final weeks
Tehran plays down reports that Trump wanted to attack Iran’s nuclear sites
News reports suggesting that Donald Trump had to be persuaded not to attack Iran’s nuclear sites have been downplayed by officials in Tehran, but nevertheless underscored the prospect of a dangerous few weeks ahead in the Middle East amid fears the US president may be planning a final push against Iran.
The report in The New York Times, which was confirmed by The Wall Street Journal, described a meeting late last week in which several senior advisers – including the vice-president, Mike Pence; the secretary of state, Mike Pompeo; the acting defence secretary, Christopher Miller; and General Mark Milley, chairman of the joint chiefs of staff – purportedly convinced Mr Trump that it would be too risky to launch airstrikes on Iranian nuclear facilities, especially the uranium enrichment facility in the central Iranian city of Natanz, in the waning weeks of his presidency, which ends at noon on 20 January.
Greenland's largest glaciers likely to melt faster than feared: study
The three largest glaciers in Greenland -- which hold enough frozen water to lift global sea levels some 1.3 metres -- could melt faster than even the worst-case warming predictions, research published Tuesday showed.
Until 2000, the main driver of sea level rise was melting glaciers and the expansion of ocean water as it warms.
But over the last two decades, the world's ice sheets atop Greenland and Antarctica have become the single largest source of sea level rise.
