Halfway to net zero; hydrogen as a fuel; Fagradalsfjall, Iceland’s active volcano

The UK is reportedly halfway towards meeting its 2050 target of "net zero" carbon emissions. How did we get there and how will we achieve the next stage?

‘UK greenhouse gas emissions in 2020 were 51% below 1990 levels, according to a new Carbon Brief analysis. This means the UK is now halfway to meeting its target of “net-zero” emissions by 2050.’ Simon Evans explains his predictions from the report, outlines how we define net zero and what is required from the next few decades to ensure that the UK meets its 2050 goal.

Much of Europe is attempting to replace fossil fuels, transforming transport and domestic heating to run on electrical alternatives, such as batteries and heat pumps. But where electrification isn’t possible or cost effective, such as in many homes, an alternative is still needed. Natural gas is responsible for over 30% of the UK’s total carbon emissions. Hydrogen would, theoretically, appear to be the perfect alternative, as combustion only produces water as a by product. Gaia discusses the options with hydrogen strategist, Dr Jenifer Baxter, and Dr Angela Needle of Cadent explains the pilot projects the company is carrying out to introduce 20% hydrogen into gas going into our homes.

Last Friday, Fragradalsfjall began erupting for the first time in 800 years. The volcanic system is located in the West of Iceland close to the capital city of Reyjkavik. Dr Evgenia Ilynskaya of Leeds University has been out measuring the gases emitted by the eruption and she describes the experience of working on an active volcanic system.

COP29: Are climate summits working?

COP29: Are climate summits working?

This year is set to be the world’s hottest on record, likely shattering the aspiration to limit global warming to 1.5C above pre-industrial levels. So where does this leave COP29, the upcoming UN climate conference in Azerbaijan? This week Inside Science is asking, are climate summits really working? What is the point of them - and are they doing enough? Joining Marnie Chesterton to discuss this are: - Joanna Depledge, expert on international climate negotiations at the University of Cambridge - Mark Maslin, climate change professor from University College London (UCL) - Jim Watson, professor of energy policy, also from UCL Presenter: Marnie Chesterton Producers: Ella Hubber, Sophie Ormiston & Gerry Holt Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth If you want to test your climate change knowledge, follow the links on this page to The Open University to take a quiz.

Whatever happened to graphene?

Whatever happened to graphene?

Twenty years ago this week two physicists at the University of Manchester published a ground-breaking paper describing the extraordinary qualities of graphene. The thinnest and strongest material known to exist – and better at carrying electricity than any metal – its discovery was hailed as revolutionary. But two decades on, it doesn’t seem to have changed the world, or if it has, it is doing so very quietly. So, what happened? We go on the trail of graphene, meeting Nobel Prize winner and Godfather of Graphene Andrew Geim, and learning what it has – and hasn’t – done and what might be next... Also this week, how to kill an asteroid and we talk the “other” COP with chief scientific adviser to the government, Dame Angela McLean.

Are our carbon sinks failing?

The Earth’s natural carbon sinks absorb half of our pollution. But now, they appear to be collapsing. Why is this happening – and will we be able to reach our climate goals without them?Also this week, why a psychologist won the Nobel Prize in Physics, the culprit behind the second biggest mass extinction event, and does playing video games make you smarter?Presenter: Marnie Chesterton Producers: Sophie Ormiston, Ella Hubber, Anna Charalambou Editor: Martin Smith Production Co-ordinator: Andrew Rhys Lewis BBC Inside Science is produced in collaboration with the Open University.

Should we bring back extinct animals?

A woolly mammoth by 2028.That’s the bold claim from US company Colossal Biosciences, who say research is under way that will make this possible.But even if we have the technology to bring back a long dead species, should we? We hear the arguments for and against de-extinction.Also this week, what will Europa Clipper find when it heads to one of Jupiter’s icy moons and how to win a Nobel Prize.

Could coal shut-down mark new era for energy?

Could coal shut-down mark new era for energy?

“That’s the end of coal in the UK for electricity.” The UK’s last coal-fired power station has closed, ending Britain's 142-year reliance on coal. But what difference will the closure of Ratcliffe-on-Soar make – and could it mark a new dawn for clean energy? After 20 years of research into microplastics and headline upon headline on their potential harms, how much do we really know about these tiny particles? Also this week, Marnie turns lab rat for a navigation experiment, and why are we all so obsessed with Moo Deng?

How green is space travel?

How green is space travel?

The images beamed back to Earth of the first civilian spacewalk have prompted a very pertinent question from one Inside Science listener: What effect is space travel having on our climate? We're used to delving into the carbon footprint of Earth-bound travel – so this week we’re going to explore the impact of the rapidly growing space industry on our climate. How does a rocket launch compare to a flight taking off? Do we even know the true cost yet – and if it’s significant, what might the solution be? Also on the programme, a personal perspective from a remote island on worrying seabird declines, the results of a project to refreeze Arctic sea ice, and why new evidence unearthed about the Falkland Islands suggests it may once have looked very different...

Is lab-grown meat the future of food?

Is lab-grown meat the future of food?

Lab-grown meat, cultivated meat, cultured meat, in-vitro meat - whatever you call it, the industry claims it could be a game changer. Not just economically, but for feeding the planet in a sustainable way.But is it too good to be true? And will people even eat it? In this special episode of Inside Science, we take a deep-dive into lab-grown meat; visiting a production facility to see how it's made, hearing about the nuanced perspectives of British farmers, asking if this new industry can learn from the failings of GM foods, and trying to figure out what the true environmental costs of entirely new way of producing food really is.
