In the second episode of the CERES Podcast, the CERES team leaders (Dr. Willie Soon, Dr. Ronan Connolly & Dr. Michael Connolly) cover everything from using penguin poop to study climate change in Antarctica to the problems with the various “homogenization adjustments” that NOAA are applying to the global temperature records.

Summary of Episode 2
In Part 1 – the “science news round-up” – we discuss three recent papers that caught our attention in the last two weeks:
The latest results on “the greening of the Earth”, i.e., how increasing CO2 in the atmosphere is leading to more plantlife worldwide;
A paper that uses penguin poop to show that Antarctica went through a period of warming from 750-1250 AD that was similar to today;
A similar study (preprint) that uses snow petrel stomach oil sediments to reveal that Antarctica was similarly warm around 4500 BC.
In Part 2, we take a deep dive into a popular graph by the NASA Climate website that people often share to allegedly “debunk” the idea that solar activity could explain recent climate change. This graph is often shared on social media and the fact that it was “created by NASA” impresses a lot of people. But, we show that the graph is pseudoscientific disinformation – not a genuine representation of the ongoing scientific debates over the causes of recent climate change.
In Part 3, we describe some of the published research of the CERES team. In this episode, Ronan, will look at the “homogenization adjustments” that the various groups (especially NOAA) compiling global temperature records apply to the weather records before using them. He shows how these adjustments are introducing non-climatic biases into the temperature data.
