The Story of Just Stop Oil - In this episode, we delve into the disruptive tactics of the climate activist group, Just Stop Oil. From blocking petrol stations in Central London to scaling the Queen Elizabeth II Bridge, and even spray-painting the exterior of Harrods, the group's bold actions have led to hundreds of arrests but have also sparked important conversations about the climate crisis. Learn about the group's origins, motivations, and how their guerilla tactics have been perceived by the public, the media, and academic experts studying social movements.

Five years ago, the United Nations Paris climate agreement set a ceiling for global warming at well below 2 °C, ideally 1.5 °C relative to pre-industrial levels. To achieve this everyone from the United States, China, the European Union, to the technology firm Microsoft and even an alliance of European airports are saying they will achieve “net-zero” greenhouse gas emissions this century. But what is Net Zero? And is it the solution to global warming?

While the growth of global emissions has slowed in recent years, there is a large and growing gap between current commitments and what would be needed to avoid exceeding these global temperature limits. Carbon Brief has provided an analysis of when the world is expected to pass these limits in the absence of large future emissions reductions. Their analysis shows that: The world will likely exceed 1.5C between 2030 and 2032 in scenarios where emissions are not rapidly reduced The 2C threshold will likely be exceeded between 2043  in the highest emissions scenario In a scenario of modest mitigation – where emissions remain close to current levels – the 2C threshold would be exceeded around 2052.

On today’s podcast we will answer the question  is climate change getting better? While this year will be memorable for many reasons, it is now more likely than not that 2020 will also be the warmest year for the Earth since reliable records began in the mid-1800s. The first nine months of the year saw record concentrations of major greenhouse gases – CO2, methane, and nitrous oxide – in the atmosphere - driven by human emissions from fossil fuels, land use and agriculture.

Around 2.4% of global CO2 emissions come from aviation. Together with other gases and the water vapour trails produced by aircraft, the industry is responsible for around 5% of global warming.

In 2019 a high-level report commissioned by the United Nations concluded that a huge reduction in meat-eating is ‘essential’ to avoid climate breakdown and keep global heating under 2C. According to the report the average world citizen needs to eat 75% less beef, 90% less pork and half the number of eggs, while tripling consumption of beans and pulses and quadrupling nuts and seeds. So why is meat so bad for the environment?
