Climate change technology which removes CO2 from our atmosphere must be urgently ramped up, leading experts say in a new report. Scientists say big cuts in CO2 emissions won’t be enough to limit global warming – and nature alone will not remove enough of it from the air. “To limit warming to 2C or lower, we need to accelerate emissions reductions. But the findings of this report are clear: we also need to increase carbon removal too,” says lead author Dr Steve Smith, from Oxford University. The report said that to reduce future global temperatures there needs to be investment in developing technological solutions now. Until emissions and removals are balanced – so called “net-zero” – global temperatures are predicted to rise.
