Many observers expect the latest UN climate report to say that warming beyond 1.5 degrees is already locked in. So what are we going to do about it? emissions climate
The Swedish scientist Kenneth Möllersten was at a conference in Cairns back in 2000 when an idea came to him that has become woven into the very fabric of international climate change politics, an idea some see as dangerous, some as fanciful, and others as crucial to stabilising the world’s atmosphere.
By 2000 scientists had been warning for decades that the world needed to drastically reduce greenhouse gas emissions or risk dangerous global warming. Small steps, like the signing of the Kyoto Protocol in 1997, had been taken. Faith in a technological solution to climate change rather than in massive, costly and immediate cuts to emissions is central not only to the Australian government’s climate response, but to the far more ambitious goals of the United States government.
The report of the first working group will be the product of billions of dollars in scientific investment and millions of hours of research by thousands of scientists around the world. Indeed many observers expect the report to say that warming beyond 1.5 degrees is already locked in due to the amount of carbon dioxide in the atmosphere.
Three years ago the IPCC itself issued a report saying that limiting warming would require “rapid and far-reaching” transitions in land, energy, industry, buildings, transport and cities.
