The wires are beginning to buzz with the news that a new set of climate talks are about to begin in Berlin. The reports are all breathless with the news that UNFCCC Climate boss Christiana Figueres reckons that it's worse than we thought.
As UN climate chief Christiana Figueres urged all states to turn political pledges into concrete action to save the planet, observers and developing states insisted the rich world should commit to tougher reduction goals.
Figueres cited new research which predicted Earth's temperature rising by as much as five degrees Celsius (41 degrees Fahrenheit) from pre-industrial levels on current pledges, instead of the 2 C limit being targeted.
It may be, however that it is Ms Figueres' mathematics that is "worse than we thought".
