Climate change talks kick off 140 world leaders gather paris

You're referring to the 2015 United Nations Climate Change Conference, also known as COP21 or the Paris Climate Conference. Here's a brief summary:

Event: 21st Conference of the Parties (COP21) of the United Nations Framework Convention on Climate Change (UNFCCC) Location: Le Bourget, Paris, France Date: November 30, 2015 - December 12, 2015 Attendance: Over 140 world leaders, including heads of state and government, as well as representatives from nearly 200 countries Objective: To achieve a new global agreement on climate change, replacing the Kyoto Protocol, which was set to expire in 2020.

The conference was a historic moment in the fight against climate change, as world leaders came together to negotiate a new agreement to limit global warming to well below 2°C (3.6°F) above pre-industrial levels and pursue efforts to limit it to 1.5°C (2.7°F).

The Paris Agreement, adopted on December 12, 2015, was a landmark achievement, as it:

  1. Set a long-term goal to limit global warming to well below 2°C (3.6°F) and pursue efforts to limit it to 1.5°C (2.7°F).
  2. Encouraged countries to submit Nationally Determined Contributions (NDCs) to reduce greenhouse gas emissions.
  3. Established a global stocktake every five years to review progress and increase ambition.
  4. Created a loss and damage mechanism to support vulnerable countries affected by climate-related disasters.

The Paris Agreement entered into force on November 4, 2016, and has since been ratified by over 180 countries, making it one of the most widely adopted international agreements in history.

The conference was a significant step forward in the global response to climate change, and its outcomes have had a lasting impact on international climate policy and action.
