Science must end climate confusion


Climate scientists need to take more responsibility about how their work is presented to the public, suggests the Met Office's Richard Betts. In this week's Green Room, he says it is vital to prevent climate science being misunderstood or misused.

Recently, I gave a talk on climate change in my local village hall in Devon, and not surprisingly I was given a hard time.

In fact, it started two days before that. Cut off from work by the snow (which, incidentally, had been forecast with almost pinpoint accuracy), I was out with the kids and being teased by the other dads.

"Where's all this global warming you're always on about, ha ha!"

The usual stuff, leading to the usual somewhat nerdy discussion on the difference between weather and climate, which was then cut short when one of the children crashed their sledge and asked if we had got that on video to send to a TV show such as You've Been Framed.

Of course, we are seeing the same comments in some parts of the press and on Twitter, from those who jump on any bit of cold weather to say it proves that global warming is not happening and we're all a bunch of idiots (or worse).

No matter how many times we say that "global warming" means a rise of average temperature across the world, decade by decade, and not every year being consistently warmer than the last in every place on Earth, there are still those that get this mixed up.

Warming world


Yes, we have had the coldest December in the UK for 14 years and now we are having a big freeze in early January; but the UK covers less than half of one thousandth of the Earth's surface.
   

Journey through climate history


Last year was actually the fifth warmest year on record as far as global temperatures were concerned.

The four warmest years were, in ascending order, 2002, 2003, 2005 and 1998. The last decade was the warmest on record, followed by the 1990s and then the 1980s, so the world is definitely warming up.
