United States(US) President Barack Obama, who has spent most of his almost two-terms in the White House advocating for protection of the environment, has called the new Paris Agreement on Climate Change: "...the best chance we have to save the one planet that we've got."
And the President's remarks are fitting since there is "No Plan B" for the human race in light of the environmental challenges and disasters man-made greenhouse gas emissions have had on Climate Change and the potential for greater calamity if left unchecked.
That global temperatures have risen 1.8 degrees Fahrenheit( 1 degree Celsius) since the pre-industrial era, with melting polar ice caps, rising sea levels and poisoning air quality in cities like Beijing, China, the Paris Agreement on Climate Change, CPO, 2015, holds global nations accountable unto themselves for limiting the amount of temperature-rising greenhouse gas emissions into the environment.
Though the Paris Agreement is not perfect, as agreed upon by the some 200 nations, who bravely rebuffed terrorists threats to meet in the French capital, the agreement stands a historic undertaking by the human race to slow the pace of global warming and to reign in the carbon footprint of this generation.
Among the aspects of the Paris Agreement are:
a pact to limit greenhouse gas emissions "as soon as possible" with a view that by 2050 these emissions would be reduced to levels that could be absorbed by the oceans and forests;
an agreement to set national standards to reducing greenhouse gas emissions every five years with more than 180 nations already submitting targets for the first-cycle in 2020 with a provision to review the goals in the next four years;
agreed no penalties for missing targets but all countries must report on their emissions and their efforts to reduce them with some "flexibility" for developing countries;
developed nations have pledged $100 billion annually from 2020 for poorer nations to make the transition to cleaner energy;
and the agreement recognizes loss and damage by smaller islands associated with Climate Change disasters, but it does not assign liability and compensation.
Henceforth, the people of the world have taken a stand to combat Climate Change anew at Paris, France, 2015, and from this year onward, humankind has pledged to re-assume the responsibility of guardianship of the environment for future generations of humans.
