At the United Nations COP27 climate conference in Egypt, UN Secretary-General Antonio Guterres claimed that the world is on a "highway to climate hell with our foot still on the accelerator (油门)". To keep temperature from rising 1.5 degrees Celsius above preindustrial levels by 2100,we need to pull a stop on greenhouse gas emissions. In fact, we'd basically have to bring the runaway truck to a complete and immediate stop. Now is the time for us to pull back before it is too late.
The climate pledges (承诺) made by nations at last year's COP26 conference felt like a positive step in the right direction, but there's very little doubt that the average temperature rise on Earth will pass the 1.5-degree mark in the coming decades. Can we limit this overshoot? And how might we do that?
A study, released Thursday in the scientific journal Nature Climate Change, tried to answer those questions by modeling 27 different emissions reduction pathways of varying ambition. It came to an unsurprising conclusion:Countries need to act by increasing the ambition of their climate pledges. And they need to act now.
The 1.5-degree rise has long been seen as a critical mark in the fight against climate change. Since the signing of the Paris Agreement at COP21 seven years ago, scientists have studied how this level of warming above preindustrial temperatures would affect the Earth. The models they've built show we are likely to see more extreme weather events, in addition to glacial melt, sea level rise that threatens many low-lying Pacific nations and significant loss of biodiversity once temperatures push past an increase of 1.5 degrees.
Though the 1.5-degree target is practically dead, the situation isn't hopeless. Now more than ever, there's reason to reduce greenhouse gas emissions by setting more ambitious goals. However, ambition alone is not enough. We also need action — investing in renewables and technologies like carbon capture and rapidly transforming our energy systems.
