US President Donald Trump is set to announce his final decision on Thursday, whether or not the United States will remain in the Paris climate agreement.

With the President favoring an exit according to a source, Trump ended his announcement on Twitter with “MAKE AMERICA GREAT AGAIN!”

Scientists have said that a US withdrawal from the deal could heighten the effects of global climate change, resulting to heat waves, floods, droughts, and more frequent violent storms.

However, the President, despite being skeptical over laws and regulations on environmental concerns since his 2016 campaigns, has still discussed with the senior White House staff a lesser harmful provision should the US continue with the treaty.

During his campaigns, Trump vowed to “cancel” the Paris deal within 100 days of becoming president on January 20, to bolster US oil and coal industries. However, advisers, close allies, corporate CEOs, Democrats and some fellow Republicans convinces him to to keep the United States in the accord and delay his decision.

Possibly leaving a 195-nation accord, the United States, under former President Barack Obama, had committed to reduce its emissions by 26 percent to 28 percent from 2005 levels by 2025.
