Last week Jillian Ambrose and Damian Carrington published a front-page story that revealed the vast scale of the profits that eight of the biggest oil firms made in three months as the Iran conflict sent energy prices soaring and the emissions-fuelled climate crisis caused deadly heatwaves.

They will be online at 2pm to answer your questions about their reporting – and any others you might have about how the oil markets work – and how many of these companies have withdrawn from their commitments to a clean energy transition.

As the Guardian’s energy correspondent, Jillian’s recent reporting has also included the spike in demand for solar power in the UK; the political row surrounding how Great Britain’s grid operator was managed during recent heatwaves and what is holding back a British green energy transformation.

Damian’s recent work as environment editor has included looking at how the climate crisis has accelerated the scale of Europe’s summer heatwaves; an audacious plan to refreeze the Arctic and a fascinating piece looking at how nature can help treat mental illness.
