also known as vapour trails &#8211; are made when the hot exhaust from aircraft engines meets the cold air at high altitude, creating ice crystals.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">Many disappear quickly, but in particularly cold and humid conditions they can persist and spread, forming clouds which trap heat that would otherwise escape from the Earth.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">Dr Paul Hodgson, Google&#8217;s technical lead for the operation, told the BBC&#8217;s Tech Life programme his five-year-old has a more colourful description for the white lines &#8211; &#8220;sky graffiti&#8221;.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">&#8220;We think that contrail warming is responsible for something like a third of all aviation climate warming,&#8221; he said.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">Dr Hodgson acknowledged there was uncertainty around the precise figure, but said scientists were confident it was &#8220;either quite a large problem or a very large problem&#8221;.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">The project also comes as the government backs expansion of UK airports, raising the wider question of whether tech solutions can sufficiently reduce aviation&#8217;s environmental impact as demand for flying grows.<\/p>\n<p class=\"ssrcss-1q0x1qg-Paragraph e1jhz7w10\">Google is also one of many big tech companies spending billions on new data centres &#8211; the giant, power-hungry banks of computer chips which power AI &#8211; which environmentalists are concerned will contribute even more to climate change.<\/p>\n<\/div>\n<p><!-- \u603b\u5bb9\u5668\uff1a\u6700\u5927\u5bbd908px Grid\u7d27\u51d1\u5e03\u5c40 -->\r\n<div style=\"display: grid;
