Every year, an annual meeting of all nations, called COP, is held to talk about climate change. In November 2015, the COP meeting was held in Paris, France, and  it reached a landmark agreement on climate to keep a global average temperature rise to no more than 2 degrees Celsius.  The agreement is called Paris Agreement. To make the Paris Agreement officially valid, at least 55 nations needed to ratify (accept) the agreement.
