60秒科学节目（SSS）是科学美国人网站的一套广播栏目，英文名称：Scientific American – 60 Second Science,节目内容以科学报道为主，节目仅一分钟的时间，主要对当今的科学技术新发展作以简明、通俗的介绍，对于科学的发展如何影响人们的生活环境、健康状况及科学技术，提供了大量简明易懂的阐释。
“Less than 4 percent of countries are responsible for over half of the world’s greenhouse gas emissions.
Glenn Althor, of the University of Queensland.
“This means that the majority of countries are unfairly bearing the burden of a problem that they did not create.
Clearly, this isn’t fair by any definition.
It’s much like a non–smoker being trapped in a room and getting cancer from second hand smoke while a heavy smoker continues to puff away in good health.”
Althor and colleagues at the University of Queensland and the Wildlife Conservation Society have just published a study analyzing the contributions to climate change by the world’s nations versus the effect that climate change will have on those countries.
“We found that developed nations, such as Australia, the United States, Canada and Russia, are essentially climate free riders, driving the problem of climate change while incurring relatively few of the costs, such as devastating flood, increased extreme weather and rising sea levels.”
Meanwhile, the most vulnerable countries, many of which are in Africa or are small island states, produce few greenhouse gas emissions.
The study is in the Nature publication Scientific Reports.
While it’s important that this issue is defined by scientists, it needs to be acted on by global leaders.
The Paris Climate Agreement, finalized in December last year, was widely seen as a positive step forward in addressing climate change.
However, there must be an urgent and meaningful mobilization of the policies outlined in the Paris Agreement if we’re to help the most vulnerable countries adapt to climate change while achieving global emissions reductions.”
