Lake Sihwa in South Korea is home to the world’s largest operating tidal power station, using the tides to generate enough power for a city of half a million people. This regular rise and fall of the seas is more predictable than sunny or windy weather and can be forecast years in advance.

The technology for harnessing tidal energy has been around for more than half a century and the potential to create energy from the sea is huge. Yet tidal power only accounts for a tiny proportion of the global renewable energy mix. Presenter Graihagh Jackson finds out what’s holding tidal power back.

The future of flying might depend on used cooking oil, plants and green electricity. Sustainable aviation fuels, known as SAF, are made from less carbon-intensive processes and renewable sources. Airlines are touting them as the key to decarbonising flying.

The aviation industry has pledged to move from 2.5% of all global CO2 emissions to net zero by 2050 – with these alternative fuels being the cornerstone of the strategy. However, there’s little SAF actually being produced, it, and it’s much more expensive than fossil fuels. Can the technologies really take off?

Climate Question host Graihagh Jackson investigates, with reporting from the BBC's Monica Miller in Malaysia and Singapore.

The deal at this year's COP conference in Dubai is being hailed as "historic" because it's the first time nearly 200 countries have all acknowledged the role of fossil fuels in Climate Change. But critics says the agreement is riddled with loopholes, and that the pledge to "transition" from oil, gas, and coal is too weak.

So who's right? And what difference will this year's discussions make? Graihagh Jackson gets the low-down from COP from BBC Climate Editor Justin Rowlatt, and she talks to three leading experts on Climate Change diplomacy.

As the world’s attention turns to this year’s COP summit in the UAE, questions remain about the host country and conference president.

It’s not the first time that an oil-producing country has hosted the climate change summit. But some environmental campaigners are unhappy about COP28 being held in the United Arab Emirates, and the choice of conference president, Dr. Sultan Al-Jaber – the CEO of the national oil company, ADNOC.

However, supporters say that the country is extremely vulnerable to the effects of climate change, so it has as much of a right to host the conference as anyone else. Meanwhile, Dr Al-Jaber boasts considerable experience working in renewables – having previously run the UAE’s renewable energy company MASDAR.

So what’s really going on? To find out more, presenter Graihagh Jackson is joined by:
