改变世界的6℃ (2007)

《6度 一个愈来愈热的星球》（原文：Six Degrees: Our Future on a Hotter Planet）是一本马克·林纳斯编写的关于全球变暖的科普书。

内容

马克·林纳斯参考气候变化史和各种气候模型的研究，分别以“一度”到“六度”为每章的标题，描述全球平均上升1到6摄氏度的后果，并在最后一章“未来”警告世人不能跨越气温上升2℃的门槛，必须在2015年前减碳。

电视节目

本书获英国皇家学会科学图书奖后，美国国家地理频道将其改编为电视节目，名为“Six Degrees Could Change The World”（6度可以改变世界）。

Six Degrees: Our Future on a Hotter Planet is a 2007 non-fiction book by author Mark Lynas about global warming. The book looks and attempts to summarize results from scientific papers on climate change.

Contents

The first chapter describes the expected effects of climate change with one degree Celsius (1 °C) increase in average global temperature since pre-industrial times.

The second chapter describes the effects of two degrees average temperature and so forth until Chapter 6 which shows the expected effects of an increase of six Celsius degrees (6 °C) average global temperature. The effects are also compared to paleoclimatic studies, with six degrees of warming compared back to the Cretaceous.

Special coverage is given to the positive feedback mechanisms that could dramatically accelerate climate change. The book explains how the release of methane hydrate and the release of methane from melting permafrost could unleash a major extinction event. Carbon cycle feedbacks, the demise of coral, the destruction of the Amazon rainforest, and extreme desertification are also described, with five or six degrees of warming potentially leading to the complete uninhabitability of the tropics and subtropics, as well as extreme water and food shortages, possibly leading to mass migration of billions of people.

TV show

A National Geographic Channel TV programme, Six Degrees Could Change The World, was produced after the book won the Royal Society Prize in 2008.

2020 Update

In April 2020, the author published a rewritten and updated version of the book: Our Final Warning: Six Degrees of Climate Emergency (ISBN 978-0008308551).
