Scientists say that Global warming might reach dangerous levels even sooner if the U.S. doesn’t follow through with its pledge to cut down carbon dioxide pollution. This is due to America’s huge contribution to the increasing temperatures.

U.S. President Trump, who once termed global warming as a Chinese trick, said in a statement on Twitter that he is yet to decide whether or not the U.S. will stay in the Paris climate change deal in which other G-7 nations have agreed to reduce its greenhouse gas emissions.

U.S. to join the climate pact

Leaders of the G-7 nations, at a meeting held in Italy, urged President Trump to commit to the pact, but reiterated in their closing statement that the U.S. was not in a position to join the consensus for now.

German Chancellor Angela Merkel expressed her dissatisfaction in the talks, stating that it was unsatisfactory and very difficult. Italy’s Prime Minister hoped the U.S. made a decision soon and rightly.

In a bid to fully grasp the potential effect on the planet if the U.S.

pulls out of the Paris deal, sources consulted with over twenty-four climate scientists to predict the possible outcome using a special computer model scenario.

Scientist predict rapid increase in carbon dioxide emissions

Scientists said it will make matters worse and reduce the chances of crossing a dangerous global temperature threshold. Estimations predict a yearly increase of over 3 billion tons of extra carbon dioxide. This might in turn yield a rapid rate of ice melt, sea level increase, and more extreme weather.

A worst-case scenario was played out by an expert group using a computer simulation to predict the possible outcome if the U.S. does not curb emissions, while other nations follow through with the agreement. It showed that America would increase global warming by 0.3 degrees Celsius in ten years to come. However, scientists have different views on the likelihood of that scenario.

Renewable energy to turn the tides

Due to the relatively low price of natural gas over coal as well as the growing promotion of sources of renewable energy, the U.S.

is still likely to reduce its carbon pollution even if it abandons the pact, thereby reducing the effects, sources claim.

Others predict that other countries may follow in the U.S. steps to exit the accord, thereby causing more emissions. Though opinions may differ on the computer simulations, they all agree that the planet would undergo a more rapid and intense warming.
