• It will be too late to tackle the climate crisis if the COP26 summit is not a success, British naturalist David Attenborough warned world leaders.
  • The summit in Glasgow is of vital importance to unify actions to limit the effects of climate change.
  • The U.N. said greenhouse gas concentrations had hit a record last year and the world was "way off track" in capping rising temperatures.

British naturalist David Attenborough warned world leaders it would be too late to tackle climate change if a U.N. climate summit in Scotland does not succeed, and said richer nations had a moral responsibility to act.

Britain has cast the United Nations COP26 climate conference which began in Glasgow on Oct. 31 as the last big chance to slow rising temperatures, and hopes to persuade leaders to adopt tougher climate targets.

Attenborough, 95, told the BBC it would be "really catastrophic" if richer nations failed to support poorer ones, and time was running out.

"Every day that goes by in which we don't do something about it is a day wasted," he said. "If we don't act now, it'll be too late."

The U.N. said greenhouse gas concentrations had hit a record last year and the world was "way off track" in capping rising temperatures.

British Prime Minister Boris Johnson said it was "touch and go" as to whether COP26 would succeed in securing the requirements needed to limit the rise in the average global temperature to 1.5 degree Celsius above pre-industrial levels and to achieve net-zero carbon emissions by 2050.

Attenborough said leading nations had a duty to help poorer countries because industrialisation had been one of the major factors in driving climate change. He warned that whole parts of Africa would become unliveable.

What’s the World Economic Forum doing about climate change?

Climate change poses an urgent threat demanding decisive action. Communities around the world are already experiencing increased climate impacts, from droughts to floods to rising seas. The World Economic Forum's Global Risks Report continues to rank these environmental threats at the top of the list.

To limit global temperature rise to well below 2°C and as close as possible to 1.5°C above pre-industrial levels, it is essential that businesses, policy-makers, and civil society advance comprehensive near- and long-term climate actions in line with the goals of the Paris Agreement on climate change.

The World Economic Forum's Climate Initiative supports the scaling and acceleration of global climate action through public and private-sector collaboration. The Initiative works across several workstreams to develop and implement inclusive and ambitious solutions.

This includes the Alliance of CEO Climate Leaders, a global network of business leaders from various industries developing cost-effective solutions to transitioning to a low-carbon, climate-resilient economy. CEOs use their position and influence with policy-makers and corporate partners to accelerate the transition and realize the economic benefits of delivering a safer climate.

Raging fires in Australia and the United States were still being dismissed by some as one-off incidents, he said, even though extreme weather events had shown climate scientists were correct to have been warning about rising temperatures in the last 20 years.
