What a year! I’ve put together some of my top pics from 2021, from Greenland to Glasgow. Enjoy 🇬🇱👇🏴󠁧󠁢󠁳󠁣󠁴󠁿

They say hindsight is 2020. When we look back on the COP26 Climate Conference in Glasgow, what will we remember?Sometimes numbers tell a story better than words or images can. The post-COP number that stands out for me is 2°C.At 2°C above pre-industrial temperatures we lose 99% of our coral reefs.

They say three is a magic number. When it comes to temperature, I know this to be true. For a cold-water swimmer, a 3°C change makes a world of difference.The same is true for our planet.

I'm about to swim where I shouldn't be able to, for the second time in my life. All because of ice – or the lack of it.

When I decided to swim the length of the English Channel, I didn't just dive in at Land’s End and hope for the best.I assembled the very best team. We drafted a training programme. We prepared exceptionally hard. I tried to eat the correct foods. And I made sure my mind-set was right.

My expedition to Greenland started with an idea. I wanted to tell a story about what is happening in our polar regions. To demonstrate the speed and scale of the climate crisis. And take that message to Glasgow for #COP26.
