On Our Way Back to 'Normal'?

There was a dip in carbon dioxide emissions, due to the Covid-19 pandemic. In spite of this, record high levels of this gas in the atmosphere, have been noted at the Mauna Loa Observatory in Hawaii (https://www.theguardian.com/environment/2021/apr/07/carbon-dioxide-levels-in-atmosphere-reach-record-high). The Mauna Loa Observatory is near the peak of what is, from its base on the seabed to its top, the highest mountain on the planet. Hawaii's Big Island is also divorced from major industrial activity, being located in mid-Pacific. Carbon dioxide is a major 'greenhouse gas' and the levels recorded in March, were 50% above those of pre-Industrial levels. Continued climate change, due to global heating seems inevitable, especially when companies are pressing governments to 'get back to normal'. 'Normal', in this case, presumably means resuming air travel, extraction of non-renewable energy sources, boosting space tourism etc. If lockdowns produced barely a blip in atmospheric carbon dioxide levels, 'normal' isn't going to be sustainable.
