A commenter on the most recent edition of het's AWOGWN asks an interesting set of questions: How would temperature data have been seen during the last 10,000 years prior to the peak of each of the previous Milankovich cycles? What caused the temperature to reverse course in those cycles and why would we not expect … Continue reading What did temperatures do as the last glacial minimum ended 120K years ago?

Inside an Antarctic Time Machine
Most of us interested in climate science understand the uniqueness and importance of deep ice cores. It is truly a remarkable record of many aspects of past climate including dust, methane, sea level proxies and carbon dioxide. The video below (a YouTubed TED Talk)is a very fascinating look at what it takes to retrieve one. … Continue reading Inside an Antarctic Time Machine
We Are Just Recovering From the LIA
This is just one of dozens of responses to common climate change denial arguments, which can all be found at How to Talk to a Climate Sceptic. Objection:Today's warming is just a recovery from the Little Ice Age.Answer: The problem with this argument is that it relies on an implicit assumption that there is some … Continue reading We Are Just Recovering From the LIA
No Past, No Present
This is just one of dozens of responses to common climate change denial arguments, which can all be found at How to Talk to a Climate Sceptic. Objection:Climate science can't even fully explain why the climate did what it did in the past. How can they then claim they know what is going on today?Answer: … Continue reading No Past, No Present
Historically CO2 Never Causes Temperature Change
This is just one of dozens of responses to common climate change denial arguments, which can all be found at How to Talk to a Climate Sceptic. Objection:In the geological record it is clear that CO2 does not trigger climate changes. Why should it be any different now?Answer: Given the fact that the human species … Continue reading Historically CO2 Never Causes Temperature Change
Global Warming Is Nothing New
This is just one of dozens of responses to common climate change denial arguments, which can all be found at How to Talk to a Climate Sceptic. Objection:Global Warming has been going on for the last 20,000 years.Answer: It is quite true that 20Kyr ago the temperature was some 8 to 10oC colder than it … Continue reading Global Warming Is Nothing New
Vineland Was Full Of Grapes
This is just one of dozens of responses to common climate change denial arguments, which can all be found at How to Talk to a Climate Sceptic. Objection:Newfoundland was so warm in the Medieval Warm Period that when the Vikings landed they called it Vineland and brought boatloads of grapes back to Europe.Answer: One can … Continue reading Vineland Was Full Of Grapes
Greenland Used to be Green
This is just one of dozens of responses to common climate change denial arguments, which can all be found at How to Talk to a Climate Sceptic. Objection:Greenland used to be a lovely hospitable island when the Vikings settled it. It was not until the Little Ice Age that it got so cold they abandoned … Continue reading Greenland Used to be Green
Geological History Does not Support CO2’s Importance
This is just one of dozens of responses to common climate change denial arguments, which can all be found at How to Talk to a Climate Sceptic. Objection:If you look back over the last 600 million years you see that there really is not much correlation between temperatures and CO2 levels. Clearly CO2 is not … Continue reading Geological History Does not Support CO2’s Importance
