Editor's note

By 2050, the UK needs to cut its net greenhouse gas emissions to zero, according to a major new report. Sustainable finance expert Aled Jones looks at whether such a goal is achievable, while Joe Blakey and Marc Hudson argue the target is misleading as it doesn’t factor in emissions the UK effectively exports to other countries. Meanwhile, an expert explains how his fears of climate change turned him from researcher to film maker.

British MP Gavin Williamson was sacked as defence secretary over a leaked report that Chinese telecoms giant Huawei will help build the UK’s 5G network. The controversy reflects wider fears in the West that Huawei will be used by the Chinese government to spy on them. But, Howard Yu cautions, Britain and others should not be so quick to cut Huawei out of their tech infrastructure plans.

The number of people with an extra bone in their body (the fabella, found at the back of the knee) has increased more than threefold since 1990, scientists revealed recently. But this isn’t the only supernumerary structure in the human body. Adam Taylor describes cases in the medical literature of people with 19 extra teeth and others with seven nipples.

New net zero emissions target won’t end UK’s contribution to global warming – here’s why

Contrary to the advice of the UK's climate advisers, aiming for net zero before 2050 is credible – but the country must reassess how much its future is worth.
