Global oil markets have been affected by the US Israel war with Iran, leading to higher jet fuel prices and increased attention on supply risks.

But how serious is the situation? While some experts point to tightening supply chains and regional bottlenecks, others say there is no clear evidence so far of immediate shortages.

Even so, the refining and distribution of jet fuel remains a potential vulnerability, as disruption can have notable impacts even when crude oil itself is available. With air travel crucial to trade and tourism, the resilience of fuel supply is a growing concern for economies and travellers. Can alternative suppliers and fuel sources help limit the impact of future disruption?

This week on The Inquiry, we’re asking: are countries really running out of jet fuel?

The recent Nasa Artemis II crewed mission to the far side of the Moon is a further step towards a long-term return to the lunar surface and future missions to Mars. The plan is that before the end of the decade there will be a crewed landing and the start of a Moon base. China is among those developing similar plans. Previous missions both crewed and uncrewed have provided evidence of resources that potentially could be of use here on Earth, and support human life on the Moon.

So, it’s not just the race to the Moon that’s capturing the world’s attention, but also the possible economic benefits that that might bring with it. The Moon’s surface or lunar regolith contains volatiles like hydrogen, carbon dioxide and methane. There is evidence of minerals such as silicate and oxides and metals like aluminium and titanium, which could be extracted for building materials. And something that is rare on Earth, Helium-3, a potential resource for clean fusion energy. Governments in conjunction with private corporations are already working on the technology to extract these resources.

Concerns have been raised about the potential damage to the Moon, not only in terms of the depletion of its resources, but in terms of its scientific value and its cultural heritage. Protection ranges from established treaties that prohibit ownership of the moon, to national laws that permit resource extraction. But to date, there is no universally accepted international law in place, which explicitly permits or prohibits lunar mining.

So, this week on the Inquiry, we’re asking ‘Should we mine the Moon?’

Conflict in the Middle East has led to volatility in global oil prices, pushing up fuel costs worldwide. Previous oil shocks prompted some countries to reconsider their reliance on cars, investing in alternatives such as cycling. In some places, this has become part of everyday life, while elsewhere it has proved more contested, reflecting wider political and cultural divides.

Cycling offers benefits for health and the environment, but it is not practical for everyone. For many people, including those in rural areas or with limited mobility, cars remain everyday essentials.

As oil price volatility continues to affect motorists, questions remain about how far behaviour can change.

This week on The Inquiry, we’re asking: is it time to swap four wheels for two?

Broadcasters from The Netherlands, Ireland, Iceland, Spain and Slovenia are all boycotting May’s Eurovision Song Contest because Israel is participating.

Sources within Israel’s broadcaster say calls for it to be banned are unjustified, and organisers of the contest insist it must remain politically neutral, describing the event as "a platform for displaying the importance of peace and unity in a divided world".

The boycott has sparked one of the biggest crises in Eurovision’s 70-year history. In several cases, the position to withdraw also reflects wider pressure from politicians and public opinion. How will countries boycotting Eurovision affect the contest?’
