'Weak tea': Climate scientists push back against COP28 cheer
The HinduA UN climate deal that approved a call to transition away from fossil fuels has been hailed as a major milestone and a cause for at least cautious optimism. Humanity has between five and eight years of emissions at the current level before blowing through the "carbon budget" required to hold long term warming to the 1.5 degrees Celsius needed to avert the worst impacts of long term planetary heating, he said. He described it as a "death knell" for 1.5C, with even the less ambitious target of 2C, which carries a significant risk for triggering dangerous tipping points in global climate systems, becoming more distant. "It's hailed as a compromise, but we need to be very clear what has been compromised," said Otto, who lectures at The Grantham Institute for Climate Change. "With every vague verb, every empty promise in the final text, millions more people will enter the frontline of climate change and many will die."
