Don't overstate 1.5 degrees C threat, new IPCC head says – DW – 07/30/2023

Jim Skea, the new head of the UN's IPCC climate panel, said it was not helpful to imply that temperature increases of 1.5 degrees Celsius posed an existential threat to humanity.

In short, we aren’t on track to an apocalyptic extinction, and the new head is concerned that rhetoric that we are is making people apathetic and paralyzes them from making beneficial actions.

He makes it clear too that this doesn’t mean things are perfectly fine. The world is becoming and will be more dangerous with respect to climate. We’re going to still have serious problems to deal with. The problems just aren’t insurmountable and extinction level.

    Speaking to weekly magazine Der Spiegel, in an interview first published on Saturday, Skea warned against laying too much value on the international community’s current nominal target of limiting global warming to 1.5 degrees Celsius compared the pre-industrial era.

    “We should not despair and fall into a state of shock” if global temperatures were to increase by this amount, he said.

    In a separate discussion with German news agency DPA, Skea expanded on why.

    “If you constantly communicate the message that we are all doomed to extinction, then that paralyzes people and prevents them from taking the necessary steps to get a grip on climate change,” he said.

    “The world won’t end if it warms by more than 1.5 degrees,” Skea told Der Spiegel. “It will however be a more dangerous world.”

    Surpassing that mark would lead to many problems and social tensions, he said, but still that would not constitute an existential threat to humanity.

    Skea predicted that one difficult area might prove to be changing people’s lifestyles. He said that no scientist could tell people how to live or what to eat.

    “Individual abstinence is good, but it alone will not bring about the change to the extent it will be necessary,” Skea said. “If we are to live more climate consciously, we need entirely new infrastructure. People will not get on bikes if there are no cycle paths.”

    Skea said he also wanted to adapt the IPCC so that it could provide better and more targeted advice to specific groups of people on how they could act to combat climate change.

    He named groups like town planners, landowners and businesses: “With all these things it’s about real people and their real lives, not scientific abstractions. We need to come down a level,” he told DPA.
