The head of the IEA will unveil a plan to get to “net-zero” by 2050 ahead of the Glasgow cop. Want a clue about what it will recommend? “Almost half the emissions cuts required to move us on to a path to net-zero by 2050 may need to come from technologies that are not on the market yet.” Most carbon capture technologies would fit into this category.

Activating positive “tipping points” in human society could bring about faster action on the climate crisis, new research argues. “Tipping points” are thresholds where a very small change can have a large, sometimes irreversible, effect on a system. Scientists have previously warned that there could be a range of tipping points in the Earth’s climate that might be triggered by global heating, if actions are not taken to tackle emissions. It is feared that triggering these tipping points could lead to faster rates of climate change. In a new commentary published in Climate Policy, researchers argue there might also be tipping points in human society that, if activated, could lead to emissions being reduced much more rapidly. Study author Professor Tim Lenton, an expert in tipping points and director of the Global Systems Institute (GSI) at the University of Exeter, told The Independent: “What’s in common between tipping points in any complex system is the idea of where a small change leads to a large outcome. “There are reinforcing feedbacks that can both propel a climate tipping point but also one of these positive social tipping points.” The researchers identify two examples of where small policy changes have already led to positive social tipping points being triggered at a national level. The first example is the rapid adoption of electric cars in Norway. Globally, electric vehicles account for 2 to 3 per cent of new car sales. However, in Norway, electric cars accounted for 54 per cent of all new vehicle sales in 2019. The second example is the rapid disappearance of coal from the UK’s electricity generation, according to the research.
