I prepared and presented this presentation whilst on my Antarctic trip. It's got a few Antarctic specific references not surprisingly! Invoking the spirit of Mawson at the end is worth sharing more widely though. If you don't know Mawson's epic survival journey you should - here's a very readable summary. In short - the odds against Mawson surviving were astronomical once his companions had died, he had next to no food and precious little gear.
But he got through because he didn't give in - he gave it his all and made it. We too can achieve the seeming impossible and protect ourselves from the disasters of global warming if we give it our all.

For example, if sea ice reduces so that there is very little winter sea ice north of the Antarctic Circle then they will starve, because they need ice floes and daylight during winter time to fish
