Paris Climate Agreement Becomes International Law

The Paris Agreement to combat climate change becomes international law on Friday — a landmark demonstrating that countries are serious about tackling global warming amid growing fears that the world is becoming hotter faster than scientists expected.

So far, 96 countries, accounting for just over two-thirds of the world's greenhouse gas emissions, have formally joined the accord, which seeks to limit global warming to 2 degrees Celsius (3.6 degrees Fahrenheit). Many more countries are expected to come aboard in the coming weeks and months.

Scientists praised the speed at which the agreement, signed by 192 parties last December in Paris, has come into force, saying it underscores a new commitment by the international community to address the problem which is melting polar ice caps, sending sea levels rising and transforming vast swaths of arable land into desert.

But scientists and policy makers say the agreement entering into force is just the first step of a much longer and complicated process of transitioning away from fossil fuels, which currently supply the bulk of the planet's energy needs and also are the primary drivers of global warming.
