A global rise of 4C could shrink the world’s economy by 40%

• A new study reveals that a 4C increase in global temperatures could shrink the world economy by 40 per cent by 2100, four times higher than previous estimates.
• The study highlights the interconnectedness of global economies, emphasising that climate-related disruptions in one region can trigger chain reactions elsewhere.
• Previous models, which focused solely on local weather impacts, underestimated the economic consequences of climate change.
• The research suggests that no nation is immune to economic losses, even those previously thought to benefit from warming.
• The study reinforces the urgency of decarbonisation, advocating for deeper emission cuts to align with the Paris Agreement's most ambitious goal.
