The Paris Climate Agreement was a historic moment for global action on climate change. Signed by 195 countries in 2015, the agreement is designed to limit global temperature increases to well below 2 degrees Celsius above pre-industrial levels, and to pursue efforts to limit the temperature increase to 1.5 degrees Celsius.

However, in 2017, the United States announced its intention to withdraw from the agreement, causing consternation among environmentalists and other nations. The move was the culmination of a long-standing opposition to the agreement by President Donald Trump and his administration, who argued that the restrictions would hurt American businesses and the economy.

Since then, there have been many questions about whether the U.S. would rejoin the Paris Climate Agreement under the new Biden administration. After all, climate change was a key issue for Joe Biden during his presidential campaign, and he has made it clear that he wants to make the United States a global leader in the fight against climate change.

So, is the US back in the Paris Climate Agreement? The answer is yes. On January 20, 2021, President Joe Biden signed an executive order to rejoin the Paris Climate Agreement, signaling a major shift in U.S. policy on climate change.

The decision to rejoin the agreement was welcomed by environmentalists and other nations around the world. The United States is the world`s second-largest emitter of greenhouse gases, and its return to the agreement is seen as crucial for the success of the global effort to combat climate change.

The U.S. rejoining the Paris Climate Agreement will require significant changes to domestic policies, such as increased investment in renewable energy, stricter emissions standards, and greater cooperation with other nations. It is also expected to lead to greater investment in green technologies and the creation of new jobs in the clean energy sector.

In conclusion, the U.S. is back in the Paris Climate Agreement, and the move has been widely praised as a positive step forward in the fight against climate change. While the road ahead will be challenging, the United States has an important role to play in the global effort to limit the catastrophic effects of climate change.
