United Nations climate talks resumed Monday with negotiators urged to make progress on a deal that could see developing countries get more money to spend on clean energy and adapting to climate-charged weather extremes.

Negotiations at the UN climate summit in Baku, Azerbaijan, enter their second week today with a slew of unfinished agenda items. Why it matters: A failure to arrive at a new and far-reaching annual funding target for climate funding directed at the developing world — which climate impacts are hitting the hardest — could have knock-on effects for years.

Senior ministers are arriving in an effort to break a deadlock over the summit’s main goal: funding to help lower-income countries hit hard by global warming.
