World leaders, senior ministers and key figures in climate diplomacy have, one by one, reaffirmed their commitment to the Paris agreement this week, in response to the order by Donald Trump to withdraw the US from the pact.
The prospect of the world keeping temperatures to 1.5C above pre-industrial levels, as the treaty calls for, was damaged by the incoming US president’s move. Hopes of meeting the target were already fast receding, and last year was the first to consistently breach the 1.5C limit, but the goal will be measured over years or even decades and stringent cuts to emissions now could still make a difference.
