Paul Melia: Every one of us is going to be affected by climate deal
Environment Editor Paul Melia explains what this deal will mean for us
The Paris Agreement will have wide-reaching implications not only for the well-being of the planet but for business, households and governments.
Business as usual is no option. The deal means that countries, big and small, developed or developing, will have to radically transform their economic models and consumption patterns to bring about decarbonisation over the coming decades.
This is a profound shift in thinking, and the only fear is that it is too little too late. Average global temperatures have risen 1C over the past century, and levels of greenhouse gas in the atmosphere are at their highest in 800,000 years.
