3,947. That long ago the Earth became so cold every inch of it was entombed in ice. The whole planet became one vast snowball that had lasted for ten million years. For years the snowball theory has been dismissed as impossible. (Earth & Ice-Age) Horizon: Snowball Earth, BBC 2001
3,948. Earth has no more terrible force than an ice-age. Only five times in its four billion years existence has our planet suffered this kind of catastrophe. (Earth & Ice-Age) ibid.
3,949. When Harland presented his theory of global glaciation colleagues dismissed it as laughable. (Earth & Ice-Age) ibid.
3,950. Joe Kirschvink had cracked it: he had found the way out of the runaway freeze ... By 1990 Kirschvink had evidence that the tropics had frozen over for ten million years ... He had no physical evidence to prove the ice had melted because of an extreme greenhouse effect ... [Paul] Hoffman’s mission was to find that evidence that had eluded Kerschvink. (Earth & Ice-Age) ibid.
3,951. In 1998 Hoffman and [Daniel] Schrag made a triumphal tour of the world’s universities promoting the snowball theory. (Earth & Ice-Age) ibid.
3,952. For many biologists there seemed to be only one possible solution: there may have been a severe ice-age but not a fully fledged snowball that covered all the oceans because life-forms that should have died out are still with us. (Earth & Ice-Age & Evolution & Life) ibid.
3,953. The ice becomes clean and transparent. Because of this transparency life-giving sunlight would have been reaching down into the snowball seas. McKay realised that even at its height there would have been havens around the snowball's equator where the ice is thin enough for photo-synthetic life to cling on below. (Earth & Ice-Age & Evolution & Life) ibid.
3,954. It may just be that the snowball saga was the biggest force for the development of life the world has ever seen. (Earth & Ice-Age & Evolution & Life) ibid.
3,955. No-one knows why the snowball happened or if it could happen again. (Earth & Ice-Age) ibid.
51,265. In the Atlantic waters north of Scotland, a fisheries researcher was the first to record a warning from the deep ... Ten years ago he began to see something in the water that really alarmed him. Turrell believes that he has found evidence that a climate catastrophe is heading right towards us. If he’s right then Britain could be heading for a massive drop in temperatures. It seems we could be heading for something like an ice age. (Climate Science & Ice Age) Horizon: The Big Chill, BBC 2003
51,287. The Little Ice Age ... The coldest winter ever recorded was in 1683/4 ... Why did the sun’s spots disappear for fifty-odd years? (Climate Science & Weather & Ice Age & Sun) Horizon: Global Weirding, BBC 2012
6,109. The Northern Hemisphere was hit by the little ice age. And on the south coast of Greenland two very different societies found themselves in the firing line. (Evolution & Human Being & Ice Age & Greenland) Man on Earth with Tony Robinson III: Killer Climate
6,112. We call it The Little Ice Age ... Cold enough to freeze the River Thames in London. (Evolution & Ice Age & Thames River & Human Being) ibid.
6,117. We call it the Little Ice Age and it delivered two brutal blows to the inhabitants of medieval Europe ... The great famine ... The black death was one of the worst pandemics in history; it began not in Europe but in Asia as a direct consequence of the impact of climate change on rodents. (Evolution & Human Being & Climate & Ice Age & Famine & Pandemic) Man on Earth with Tony Robinson IV: The Modern World
4,009. The planet froze. Temperatures plummeted. Ice spread down from the poles. It encased the planet in a layer thousands of metres thick. A snowball Earth. (Earth & Ice Age) Tony Robinson, Catastrophe II: Snowball Earth
4,010. Glaciers are nature’s bulldozers. (Earth & Ice Age) ibid.
4,011. The term snowball Earth was coined by geologist Joe Kirschvink who has been gathering evidence on the theory for the past two decades. (Earth & Ice Age) ibid.
4,013. Cyanobacteria were depleting them further. In combination with weathering they sucked the carbon dioxide out of the atmosphere and temperatures plummeted. (Earth & Bacteria & Carbon Dioxide & Ice Age) Tony Robinson: Catastrophe II: Snowball Earth
4,014. A catastrophic chain reaction pushed it to the point of no return. (Earth & Ice Age) ibid.
4,016. Volcanoes are the only things on the planet hot enough and strong enough to thaw a frozen world. (Earth & Ice Age & Volcano) ibid.
4,088. 20,000 years ago our planet was in the middle of an ice age. (Earth & Ice Age) Orbit: Earth’s Extraordinary Journey II, BBC 2012
5,742. Hunting requires conscious planning and organisation by means of language as well as special weapons. (Evolution & Human Being & Language & Weapons) Jacob Bronowski, The Ascent of Man 1973: Lower than The Angels 1/13
5,743. Man moved into the north just when the climate there was turning to ice. (Evolution & Human Being & Ice Age) ibid.
5,916. Just before complex life appeared the world was in the grip of the biggest ice age in its entire history. (Evolution & Life & Ice Age) David Attenborough’s First Life 1/2
5,917. Snowball Earth ... It’s likely those conditions lasted for millions of years ... Life was nearly annihilated before it had barely begun. (Evolution & Life & Ice Age) ibid.
51,214. Scientists are telling us we’re heading into a new ... Ice age? What? It’s from Time Magazine Monday June 24th 1974. Fuck! (Climate Science & Ice Age) Penn & Teller, Bullshit! Being Green s6e6
51,288. In 1972 a group of eminent scientists sat down to write a letter to the President of the United States. They were frightened. The Earth’s climate seemed to be going haywire ... The letter warned the President he had to prepare not for global warming but for the complete opposite – a new Ice Age. (Climate Science & Ice Age) Iain Stewart, Earth: Climate Wars: The Battle Begins
51,369. The IPPC says that unless we reduce the rate of greenhouse gas emissions, the greenhouse effect will intensify and warm up our planet. Glaciers and polar ice-caps will begin to melt, rivers will burst their banks, and sea-levels will rise, the deserts will expand ... (Climate Science & Temperature & Ice Age) Global Warming: Doomsday Called Off
51,370. The temperature data from the ice-sheets reveal long periods with much higher temperatures than those we experience today. They tell a fascinating tale of natural temperature fluctuations in the northern hemisphere from times when man had no influence on the climate whatsoever. Other core samples from elsewhere in Greenland confirm that the Little Ice Age ended about a hundred and forty years ago at the coldest point in the last ten-thousand years. (Climate Science & Temperature & Ice Age) ibid.
51,371. Michael Mann’s hockey-stick graph is unusual and scientists not attached to the United Nations climate panel have found it hard to swallow. (Climate Science & Temperature & Ice Age) ibid.
51,413. In The Weather Machine  we reported the mainstream opinion of the time which was global cooling and the threat of a new ice age. (Climate Science & Ice Age) Nigel Calder
51,422. We should remember that when I was going to graduate school it was gospel that the new ice age was about to start. And to tell the truth I had trouble warming up to that one too. (Climate Science & Ice Age) Professor Patrick Michaels
129,388. In 1977 the worst winter for a century struck the United States. Arctic cold ripped the mid-west for weeks on end. Great blizzards paralysed cities of the north-east … The brutal Buffalo winter might become common all over the United States. Climate experts believe the next Ice Age is on its way. (Ice Age & Climate) In Search of s2e23 … The Coming Ice Age, 1978
