Paris climate pact now needs concrete actions

The landmark Paris agreement on climate change finally came into effect on Friday. It is a manifestation not only of the world's awareness of the increasingly devastating impact climate change as a result of human activities is having on the Earth. It is also the demonstration of the resolve of the countries that have ratified it to address the issue with concrete actions.

That is worth celebrating, even though there are about 100 countries that still have to ratify the agreement.

Yet, it is one thing to have such an official global pact. It is another to ensure that countries implement their commitments to the letter.
