Can we still avoid climate catastrophe?

BBC World Service - Unexpected Elements, Can we still avoid climate catastrophe?

The UNEP Emissions Gap Report reveals we need to do more to reach our climate goals.

The UNEP Emissions Gap Report shows we are still on track for “climate catastrophe”. Also, indigenous forests in New Zealand, climate adaptation in India, and women in STEM.

Just a few days before COP26 opens in Glasgow, the World Meteorological Organisation reported record greenhouse gas levels, despite a fall in CO2 due to pandemic restrictions. 

The UN Environment Programme’s Emissions Gap Report also revealed that current country pledges will only take 7.5% off predicted greenhouse gas emissions by 2030, well below the 55% needed to limit global warming to 1.5C. Worse still, many large emission producers are not on track to meet their countries’ pledges. Rachel Warren, Tyndall Centre for Climate Change Research, tells us the 1.5C limit is still achievable if we work in tandem with nature. 

Research by Sara Mikaloff-Fletcher, National Institute of Water and Atmospheric Research (NIWA), illustrates this. Her contribution to the WMO Greenhouse Bulletin revealed that New Zealand’s indigenous forests play a bigger role in absorbing carbon from the atmosphere than previously thought. Also on the programme, Abinash Mohanty, Council on Energy, Environment and Water, has been mapping climate vulnerability in India and explains why communities should be at the forefront of climate adaptation and mitigation strategies. And particle physicist Claire Malone shares her insights on how we can help women thrive in science, technology, engineering and mathematics (STEM) fields.

And, As the world slowly moves away from using fossil fuels for electricity, one tiny Scottish island has proved it’s possible to rely almost entirely on renewables.

The inner Hebridean isle of Eigg used to get its power from diesel generators. But in 2008 its residents launched the world’s first electricity system powered by nature, and the Crowdscience team wants to know exactly how they did it, and whether such a model could work in other places with no national grid? Marnie discovers that the community is key to the success of this project, meeting the maintenance men who taught themselves to install equipment and solve any problems themselves, and hearing from residents who’ve changed their habits to use less juice. With the mainland more than an hour away by a once-daily ferry, this kind of resourcefulness is vital. Hydroelectric generators harness the power of running water and are complemented by wind turbines and solar panels on peoples roofs, meeting 95% of Eigg’s energy needs. Now others are learning from this unique experiment and we meet the Malawians who were inspired after visiting Eigg. A solar grid in the village of Sitolo has provided power to thousands of people, and the people who designed it are planning others.
