Thousands of climate protestors take to the streets of New York to demand end to fossil fuels

Tens of thousands of people took to the streets of New York on Sunday, calling for increased action against climate change ahead of the opening of the UN General Assembly.

US President Joe Biden is among the world leaders set to attend the UN General Assembly, which is scheduled to formally open on Tuesday.

A UN climate report released this month named 2025 as the deadline for global greenhouse gas emissions to peak -- followed by a sharp drop afterward.

UN Secretary-General Antonio Guterres has organized a Climate Ambition summit for Wednesday, during the General Assembly, at which he hopes to accelerate the ongoing work to counter climate change by governments as well as private sector organizations and financial institutions.
