Why we need a COP21 or: how scientists know climate change is happening

Paris remains prominent in the news, thankfully, this time it’s because the world’s leaders are in the city to discuss how we’ll avoid dangerous climate change.

It comes on the back of the recently agreed Sustainable Development Goals which I drafted a blog on a few weeks back. This is the first big test of those SDGs in my opinion. I mean, if the SDGs can’t be translated into meaningful commitments towards reducing greenhouse gas emissions what is the point of the SDGs at all?

Let’s hope those world leaders come away with something meaningful. Let’s hope the debacle of Copenhagen 2009 is avoided. Let’s hope that developing and developed nations can work collaboratively to achieve this objective. If not, we’re doomed.

How do we know? Well as Professor of Climatology at University College London, explains – we do know climate change is happening. In fact, I urge you to read this superbly succinct piece to remind yourself of exactly what is known about the causes and the effects.
