COP26: Nations wrap up Week One

Delegates have wrapped up the first half of the two-week COP26 summit in Glasgow, Scotland.

In Week 1, more than 100 world leaders spoke and presented deeper reduction goals to combat climate change.

Indian Prime Minister Narendra Modi promised to cut the country's greenhouse gas emissions to net zero by 2070.

Some leaders pledged additional financial assistance for developing nations.

US President Joe Biden said, "We want to do more to help countries around the world, especially developing countries, accelerate their clean energy transition."

A key focus of COP26 is whether the delegates can agree on plans to keep the average rise in global temperatures under 1.5 degrees Celsius from pre-industrial levels.

Some international organizations estimate that if countries can achieve their reduction goals, the rise could be kept within 2 degrees by the end of this century.

One of the main issues for Week Two will be setting international rules on trading greenhouse gas emissions. The topic was included in the 2015 Paris Agreement, but no rules have been agreed so far.
