It is so important to find something you are passionate about and get involved. There is no explorer who hasn’t seen the effects of climate change, yet global agreement on solutions has been difficult as economies strive to balance economic growth against the threat of climate change. Climate change knows no borders.
That is why I have been supporting various initiatives since 2015.
COP 26
2021: COP 26/CMP 16/CMA 3, Glasgow, United Kingdom
COP 26 was originally scheduled to take place in November 2020, in Glasgow, but was postponed to early November 2021 due to the COVID-19 pandemic. Among other things, this conference led to the development of the Accelerating to Zero coalition to accelerate the phase-out of fossil fuel vehicles.
COP 21
25zero was a mountaineering project designed to track equatorial glacial melt and raise of the impacts of climate change, led by explorer Tim Jarvis AM. The project presented live footage from the peaks of three mountain glaciers to the 37,000 delegates at the COP21 summit in 2015 in Paris, France, as a way of showcasing the impact of global warming on vulnerable and remote areas.
The 25zero climbing team has varied over time depending on the expedition, although the original 2014 team comprised:
- Tim Jarvis
- Ed Wardle
- Heidi Sand
- Vanessa O’Brien
- Khoo Swee Chiow
- Barry ‘Baz’ Gray
