The Paris Agreement, which was adopted on December 12, 2015, is an international treaty aimed at combating climate change. It was hailed as a landmark agreement as it was the first time that all countries, developed and developing, agreed to work together towards a common goal of limiting global temperature rise to below 2 degrees Celsius above pre-industrial levels.

Since then, the Paris Agreement has been ratified by 189 countries. However, there have been concerns over whether the agreement is still in effect, especially after the United States, one of the largest emitters of greenhouse gases, announced its withdrawal from the agreement in 2017.

Despite the US withdrawal, the Paris Agreement remains in effect. This is because under the rules of the agreement, a country cannot withdraw until three years after the agreement takes effect. Additionally, it takes another year for the withdrawal to be finalized. As the Paris Agreement came into effect on November 4, 2016, the US cannot officially withdraw until November 4, 2020.

Furthermore, even though the US is withdrawing from the agreement, it is important to note that the country is still bound by the agreement until the withdrawal is finalized. This means that the US is still expected to reduce its greenhouse gas emissions and meet the targets set out in the agreement until November 4, 2020.

The Paris Agreement is still in effect, and most countries are committed to meeting its targets. While the US withdrawal is a setback, other countries have pledged to increase their efforts in reducing their greenhouse gas emissions. It is important that all countries work together to combat climate change and ensure that the Paris Agreement remains an effective tool in addressing this global challenge.
