Hello *Nature *readers, Today we hear that extreme steps are needed to avert climate disaster. Plus, we consider nine research priorities to address issues with cryptocurrencies and learn that controversial ‘CRISPR-baby’ scientist He Jiankui is out of jail.

The latest Intergovernmental Panel on Climate Change (IPCC) report makes it clear that the window to avert the most destructive and irreversible effects of climate change <nature.us17.list-manage.com/track/click?u=2c6057c528fdc6f73fa196d9d&id=55f923565e&e=90526406f0>is rapidly closing <nature.us17.list-manage.com/track/click?u=2c6057c528fdc6f73fa196d9d&id=355cb7f058&e=90526406f0>. It is the third of three IPCC reports that assess the scientific basis <nature.us17.list-manage.com/track/click?u=2c6057c528fdc6f73fa196d9d&id=6a47c234b2&e=90526406f0> of climate change, how bad it is <nature.us17.list-manage.com/track/click?u=2c6057c528fdc6f73fa196d9d&id=251ed858ba&e=90526406f0> and how to fix it. The report finds that:
– Governments are acting too slowly, held back by the lobbying efforts of fossil-fuel companies. – Greenhouse-gas emissions continue to rise. – Wealthy countries must lend a helping hand to the countries that contributed least to the problem but face the worst impacts.
The good news:
– We have the renewable-energy technologies we need to make the change — and they are getting cheaper. – It is possible to pull carbon pollution out of the atmosphere by expanding forests and improving agricultural practices. – The economic benefits of limiting warming — including improved health and reduced damages — exceed the cost of mitigation.

Science drives action: research into the depletion of the ozone layer has led to policy developments, real behaviour change and a positive outcome for people and the planet. To support the action needed to combat climate change, Nature Portfolio has compiled a selection of important research articles on the topics of climate action, mitigation, adaptation, justice and finance <nature.us17.list-manage.com/track/click?u=2c6057c528fdc6f73fa196d9d&id=1c05dda3a9&e=90526406f0> .

Following today’s report, the IPCC will draw up one further synthesis document for decision-makers at the COP27 climate summit <nature.us17.list-manage.com/track/click?u=2c6057c528fdc6f73fa196d9d&id=1f17d5f3db&e=90526406f0> in Egypt in November. But the research community’s work stretches far beyond the IPCC. In January, a *Nature* editorial outlined how <nature.us17.list-manage.com/track/click?u=2c6057c528fdc6f73fa196d9d&id=767fa29aa7&e=90526406f0> scientists of all stripes can offer up expertise and ensure that they have a voice <nature.us17.list-manage.com/track/click?u=2c6057c528fdc6f73fa196d9d&id=dc81c4e7c4&e=90526406f0> in this monumental effort.
