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.

It's been a tough year. We put our lives on pause while the Covid-19 pandemic ravaged our families and our businesses.It also disrupted our conservation efforts.This week 25 nations and the EU met to discuss creating a series of MPAs (Marine Protected Areas) around Antarctica.

I have always seen Norway as a moral leader, with a long tradition of helping people in need. From the work of Fridtjof Nansen repatriating refugees, to Norway’s help in ending Apartheid, you will find Norwegian peace negotiators wherever there is conflict around the world.

I didn't realise the world contained so many different shades of blue. I was surrounded by ice, with the light refracting back at me from every side. I've never been more dazzled. I was in East Antarctica, I was underneath the ice sheet, and I was swimming. It wasn't exactly what I had planned.
