In a first, U.N. climate agreement could include the words 'coal' and 'fossil fuels'

As the United Nations climate summit enters its last hours, there is modest progress on reducing reliance on fossil fuels and giving aid to countries most at risk from extreme weather. But stubborn divisions over the details of key issues remain.

In what would be a first in decades of such negotiations, nations could call for an end to using coal and subsidizing fossil fuels. Despite some weaker language, those two elements remain in the most recent draft being circulated for consensus agreement among the more than 100 participating countries.

The summit in Glasgow, Scotland, is scheduled to end Friday, but could extend into the weekend as negotiators try to nail down agreement on a range of thorny issues for their final statement.

Still, it appears that the conference, known as COP26, is set to fall far short of its overall goal of keeping global, United Nations Secretary-General Antonio Guterres says that goal is "on life support." Beyond 1.5 degrees Celsius of warming, scientists say the world faces catastrophic and potentially irreversible damage from extreme heat, drought, and flooding.
