potholer54 | Response to Bill Whittle's "Is climate change real?" @potholer54 | Uploaded June 2017 | Updated October 2024, 23 hours ago.
CORRECTIONS: I at around 8:00 I said that temperatures are now as high as they've been for the last 11,000 years, based on the Marcott paper I cite below. That's not accurate. Marcott concluded that current (transient) temperatures are now higher than 75% of the Holocene, and are set to exceed the highest Holocene temperatures over the next eight decades whatever the greenhouse gas emissions scenario.
And at about 3:30 I said 400 million instead of 400 parts per million. The meaning should be clear from the context, but excuse the slip.

04:47 – Whittle also doesn’t give a source for this graph, but I tracked down the author as Humlum at Oslo University. It hasn’t been published or peer-reviewed, it’s just being passed round the blogosphere.
5:04 – 5:18 – CORRECTION: The Arrhenius paper was 1896, not 1894. Other than that, the titles, authors and dates of these papers are ALL shown very clearly in the video.
