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 ânet-zeroâ 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 â where emissions remain close to current levels â the 2C threshold would be exceeded around 2052.

On todayâs 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 â CO2, methane, and nitrous oxide â 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.
On todayâs podcast we will answer the question ââHow bad is flying for the environment?â

In 2019 a high-level report commissioned by the United Nations concluded that a huge reduction in meat-eating is âessentialâ 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?

Is global warming is real? There is so much evidence that at least 97% of climate scientists agree that humans are causing global warming. Itâs as settled as the link between smoking and cancer. So why do so many people still think it's a hoax?

On todayâs podcast we will answer the question âWhat is the Green New Dealâ?
If youâve heard a lot recently about the Green New Deal but still arenât quite sure what it is, you are not alone. It has been trumpeted by its supporters as the way to avoid planetary destruction, and vilified by opponents as a socialist plot to take away your ice cream. So itâs bound to be somewhat confusing. We explore its history and what it means for the climate crisis.

Extinction Rebellion have glued themselves to trains, blockaded major bridges, and chained themselves to government buildings. So who are Extinction Rebellion and what do they want?

On this special 2020 New Years Day podcast I will be discussing 3 facts everyone must know about climate change going into the new decade.
Fact 1: 18 of the 19 warmest years have occurred since 2001.
Fact 2: Carbon Dioxide Emissions Hit a Record High in 2019
Fact 3: Natural gas has become the biggest driver of emissions growth
As we enter this new decade itâs clear: we need to shift decisively away from fossil fuels (including natural gas), invest in renewable energy and focus on developing shared community based solutions to adapt to a warmer world.

Scientists predict weâre currently on track for a heating of somewhere between 3C and 4C for 2100
Four degrees may not sound like much â after all, it is less than a typical temperature change between night and day. It might even sound pleasant. However, if the entire globe heats by 4C it would render the planet unrecognisable from anything humans have ever experienced.
So, what will happen if the world becomes 4 degrees warmer?

The melting of the ice caps is one of the best known of climate changeâs many effects on planet earth. This year Arctic sea ice dropped to its second ever recorded level So why is the Arctic melting?

The world is in the midst of an unprecedented oil and gas drilling rushâbrought on by a controversial technology called fracking. But along with rush have come reports of poisoned drinking water, polluted air, mysterious animal deaths, industrial disasters and explosions.
So what is fracking and what damage does it cause?

We are facing an unprecedented global emergency. Life on Earth is in crisis: scientists agree we have entered a period of abrupt climate breakdown, and we are in the midst of a mass extinction of our own making. This is leading people more and more people to ask What can I do to stop climate change?
