最後一集的《大氣已成》,全球變暖持懷疑論者,90年代一開始全球似乎是團結的。在里約全球變暖的科學解釋,氣候變化持懷疑論論者早期的一系列爭論演講。Iain Stewart博士斷定現在面對氣候科學家最大的挑戰的系列關注- 他們怎麼正確預測全球變暖會帶來甚麼影響?帶他從早期嘗試到現代氣候轉盤系統,到超級電腦,到如今氣候研究的前線:格陵蘭島的一次旅程。最焦慮是他發覺科學家的日益擔心他們的已經運行中的模型對變化的速度估計不足……
Today, the scientific debate over whether global warming is happening is all but over. Even many die-hard sceptics now concede that the planet is getting warmer, and humans are largely to blame. But there are still many unanswered questions.
This film investigates why there is so much confusion over what changes global warming is going to bring, and why this has led to uncertainty over what should be done about it.
Understanding how the climate works, and predicting how it will change in the future, is one of science's greatest challenges. Iain discovers how, 60 years ago, scientists began their experiments with little more than a dishpan, a Bunsen burner and a turntable. Today they rely on massive super-computers to model the effects of greenhouse gases on the climate. But still they struggle to understand the complexity of the climate system.
Journeying to Greenland, we meet scientists who are trying to fill in the gaps in the climate models. We also discover how scientists are becoming increasingly concerned that their models are underestimating the speed of changes already under way. |

第二集中Iain Stewart 博士在90年代調查反擊對全球變暖持懷疑論者。90年代一開始全球似乎是團結的。在里約熱內盧召開的全球峰會上全球簽署了一項行動計畫來開始應對氣候變化。即使George Bush在那,但意見至終也沒統一。
Iain闡述了科學爭論從對全球變暖持懷疑論到呈現出氣候變化支持的發展,懷疑論者幾乎抨擊科學家所掌握的每個事實,他們認為地球沒有變暖,沒有一丁點的異常,認定人類排放的二氧化碳氣體不會對氣候造成任何改變
Iain和一些全球變暖持懷疑論的主要人員會談,發覺他們已隨時間改變了態度…
Dr Iain Stewart investigates the counter attack that was launched by the global warming sceptics in the 1990s.
At the start of the 1990s it seemed the world was united. At the Rio Earth summit the world signed up to a programme of action to start tackling climate change. Even George Bush was there. But the consensus didn't last.
Iain examines the scientific arguments that developed as the global warming sceptics took on the climate change consensus. The sceptics attacked almost everything that scientists held to be true. They argued that the planet wasn't warming up, that even if it was it was nothing unusual, and certainly whatever was happening to the climate was nothing to do with human emissions of greenhouse gases.
Iain interviews some of the key global warming sceptics, and discovers how their positions have changed over time. |

全球變暖,如何與之戰鬥,引起了激烈的爭論,如何看待地球這種變化成了世界範圍裡的頭條新聞,但科學家甚麼時候怎麼發現全球變暖的?為甚麼這會導致激烈的爭論?我們應該相信麼?一連三集的《大氣已成》中,地質學Iain Stewart對氣候變化的歷史有個權威的指導介紹。
首集講述70年代世界似乎崩潰離析。從酸雨到人口過剩,對生態的憂慮成了頭等大事。這時氣候的變化首次成了政治熱點。但科學家害怕是不是全球變暖,而是完全相反,一個新的冰河時代。
Iain Stewart博士從開始追蹤氣候變化的歷史,仔細檢查了科學界在70年代怎麼得到這麼多的錯誤回饋的。沿著這樣的方法他揭開了一些偉大的氣候變化學科的無名英雄,向我們介紹一位神秘的美國政府機構的科學家,稱為約翰,早在1979年就寫了第一份關於全球變暖的政府報告。
他顯示了在80年代晚期,全球變暖已經成了一嚴重的政治爭論,看起來仿佛需要聯合起來共同行動。但結果是一個錯誤的開始。因為在90年代全球變暖已轉變成一個最大的科學爭論。
In the early 1970's scientists warned that we faced a new ice age. Now they’re convinced the greatest threat to civilisation is global warming. In between times – and until very recently – confusion has continued to reign in the issue of climate change.
This authoritative series travels the globe to chart this astonishing scientific turnaround, and shows how we know what we know. Over three episodes – The Battle Begins, Fight Back and Fight for the Future – it explains how we became aware that climate change was happening, examines the proof that it is a man-made problem and asks how close we are to the point of no return.
First episode of Climate Wars, Dr Iain Stewart traces the history of climate change from its very beginning and examines just how the scientific community managed to get it so very wrong back in the Seventies. Along the way he uncovers some of the great unsung heroes of climate change science, and introduces us to a secret organisation of American government scientists, known as Jason, who wrote the first official report on global warming as far back as 1979.
He shows how - by the late 1980s - global warming had already become a serious political issue. It looked as if the world was uniting to take action. But it turned out to be a false dawn. Because in the 1990s global warming would be transformed into one of the biggest scientific controversies of our age. |
