LONDON: Queen Elizabeth II on Monday appealed to world leaders to work together in "common cause" against climate change to "solve the most insurmountable problems", reports AFP.
The statement, delivered in a video message to the COP-26 conference in Glasgow came after a day of speeches from world leaders warning of the urgency of the crisis.
She added: "None of us underestimates the challenges ahead: but history has shown that when nations come together in common cause, there is always room for hope."
Earlier, UN Secretary General Antonio Guterres had issued a similarly stark warning.
"We are digging our own graves," he said, referring to the current exploitation of the planet's resources.
But some observers have already denounced what they see as a lack of action to back up the statements from world leaders.
