Greta Thunberg has slammed the G7 Summit for indulging in a "steak and lobster" barbecue while watching "jet planes perform aerobatics" during their gathering over the weekend.

The teen climate activist shared her criticism with her 4.9 million followers as she once more took issue with world leaders and their handling - or lack thereof - of the climate crisis.

She wrote: "The climate and ecological crisis is rapidly escalating. G7 spends fantasy amounts on fossil fuels as CO2 emissions are forecast for 2nd biggest annual rise ever.

"This calls for steak-and-lobster-BBQ-celebration while jet planes perform aerobatics in the sky above the G7 resort!"

In a follow-up post, Greta said: "The G7 leaders really seem to be having a good time presenting their empty climate commitments and repeating old unfulfilled promises."

The G7 summit saw participating countries agree to step up the fight against climate change as they renewed a pledge to raise $100bn a year in order to help economically disadvantaged countries reduce greenhouse gas emissions, BBC News reports.

However, there appeared to be a discrepancy between what the leaders at the three-day meeting in Carbis Bay, Cornwall, said about the urgency of reducing emissions and their own actions.

Boris Johnson, who hosted the affair, arrived in Cornwall by private jet - despite being able to reach the destination by car or train.

And as Greta mentioned, the Prime Minister arranged an air performance by an RAF aerobatics troupe known as the Red Arrows, which pumped out the colors of the UK flag during their flyover.

In any case, her tweet attracted hundreds of responses, with many agreeing with 18-year-old Swede's stance on the matter.

One person commented: "There is no 'they' we can count on to address the climate emergency. The G-7’s climate discussion is a puppet show—with finger puppets. We are in such terrible trouble, and yet we keep voting these corporate shills into office. #ClimateCrisis."

Another wrote: "Our leaders are completely clueless. Mouthing platitudes about the climate emergency while watching a jet show? This illustrates a cavalier disregard for the human rights of billions of people."

A third remarked: "Celebrate G7? Cornwall is a beautiful location, but G7 has been full of empty promises with politicians having fun in the sun… It is unforgivable when young people like @GretaThunberg are more serious about the future than our elected officials."

A final user added: "Politicians just wanna have fun - why care about the climate?"
