• 00:00:00 In this section of the YouTube video titled "Stephen Andrews: Importance of cosmic rays/clouds in recent warming | Tom Nelson Pod #253," guest Stephen Andrews shares his journey from being a climate change doom advocate to an anthropogenic climate change skeptic. He was initially skeptical of the climate change narrative due to errors and inconsistencies in the data during the COVID-19 pandemic. Andrews, who has a background in science and chemistry, became curious about the hockey stick graph, a simple representation of past temperature trends. He questioned why scientists hadn't used oxygen isotope ratios in ice cores to construct a more accurate hockey stick graph. Oxygen isotopes are a proxy for temperature, and the ratio of oxygen 18 to oxygen 16 in ice cores can be used to measure past temperatures. Andrews explains that when temperatures are lower, there is less oxygen 18 in the ice, resulting in a lower isotope ratio. By measuring this ratio, scientists can accurately date and determine past temperatures. Andrews' investigation into the hockey stick graph led him to question the accuracy of the data and the accepted climate change narrative.
• 00:05:00 In this section of the YouTube video titled "Stephen Andrews: Importance of cosmic rays/clouds in recent warming | Tom Nelson Pod #253," the speaker discusses his efforts to find temperature reconstruction data from ice cores, particularly from the Renland Peninsula in Greenland. He expresses surprise that such data did not exist, given the extensive efforts made by climate scientists to obtain ice core measurements. The speaker then shares that he found two separate studies with significant overlap in their data and joined them to generate a graph comparing temperature data from 1960 to 10,000 BC and 1801 to 2014. He used a 20-year rolling average to make the data sets comparable and found no evidence of an abnormal temperature increase, or "hockey stick," during the modern period compared to the much longer timeframe. The speaker concludes that the approach of linking the two data sets is valid and emphasizes the importance of considering the appropriate time period when analyzing temperature trends.
• 00:10:00 In this section of the YouTube video titled "Stephen Andrews: Importance of cosmic rays/clouds in recent warming | Tom Nelson Pod #253," Stephen Andrews discusses his analysis of temperature anomaly data from Barkley Earth, a pro-climate change narrative site, to understand why global warming is seasonal and varies with latitude. He found significant variation in seasonal rates of warming and temperatures anomalies, which led him to question the alarming warming rates presented by the site. Andrews explained that temperature anomaly data is calculated by removing the normal seasonal variation from the temperature data, making it difficult to assess the significance of global warming when compared to natural seasonal variations. He also plotted global warming rates from 1860 to 2020 and found that the warming signal is small when viewed against the natural seasonal variations.
• 00:15:00 In this section of the YouTube video titled "Stephen Andrews: Importance of cosmic rays/clouds in recent warming | Tom Nelson Pod #253," Andrews discusses the varying warming rates across different hemispheres and seasons. He presents data showing that the Northern Hemisphere experiences much greater warming rates, particularly in winter, compared to the Southern Hemisphere. The warming rates for specific locations, such as Greenland, exhibit even more extreme seasonal variations, with warming rates being six and a half times faster in January than in July. Andrews argues that this strong seasonality and latitude impact on warming rates have not been adequately addressed by climate scientists and accuses some organizations of using simplistic and scaremongering tactics. He then plans to further analyze the data to identify potential causes of warming.
• 00:20:00 In this section of the YouTube video titled "Stephen Andrews: Importance of cosmic rays/clouds in recent warming | Tom Nelson Pod #253," Stephen Andrews presents an analysis of temperature anomalies in Greenland, revealing a greater variation in July and August compared to winter months. He also discusses the correlation between solar cycles and temperature anomalies, as shown in the data from NASA on solar forcing. Andrews concludes that the temperature anomalies in Greenland, as one of the most temperature-sensitive places on Earth, demonstrate a clear correlation with solar cycles. He also suggests that cosmic rays, which create nuclei and impact cloud formations, may have a direct link with temperature based on longer analysis data sets, such as those from Finland.
• 00:25:00 In this section of the YouTube video titled "Stephen Andrews: Importance of cosmic rays/clouds in recent warming | Tom Nelson Pod #253," Stephen Andrews discusses the relationship between cosmic rays, solar activity, and temperature variations. He uses data from the ULU Finland cosmic ray station and Sunspot number to demonstrate an inverse relationship between solar activity and cosmic rays. However, he notes that ground-level cosmic ray measurements may not be directly useful for understanding the interaction with the atmosphere. Instead, he looks for an annual signal within the data set to support the cosmic ray theory. The monthly rates for cosmic rays and temperature data show a maximum of cosmic rays in June and July and a minimum in January and December, with opposing second-order polar moment fits. Additionally, Andrews mentions Jasper Kirkby, a British physicist who conducted experiments at CERN investigating the possible physical mechanisms for solar or cosmic ray forcing of clouds in the Earth's atmosphere.
• 00:30:00 In this section of the podcast, the speaker discusses a presentation by Stephen Andrews at the CERN colloquium in 2009, where he provided evidence for the cosmic ray theory of recent warming. Andrews' evidence included a study by Holgate in 2007 that showed a relative straight line of sea level rise from 1900 to the present, but the correlation with carbon dioxide was not direct. Andrews also noted that the paper did not mention the Sun, despite the obvious correlation. Another study by Kirkby, which looked at solar cycling and overlaying it on sea level rise, also showed a correlation. More recently, a study by Nicolas and Zeller concluded that solar forcing explained 83% of the global surface air temperature trend over the last 24 years, and raised questions about the role of anthropogenic radiative forcing. The current evidence suggests that cosmic forcing, such as galactic cosmic rays, solar interplanetary magnetic fields, and solar winds, interacting with the Earth's global electric circuit, may be the drivers of cloud albeda variations.
• 00:35:00 In this section of the YouTube video titled "Stephen Andrews: Importance of cosmic rays/clouds in recent warming | Tom Nelson Pod #253," Stephen Andrews discusses the correlation between solar activity and climate change, specifically the role of cosmic rays and clouds in recent warming trends. He argues that the Earth's magnetic field, which interacts with solar winds, can divert cosmic rays and impact climate. The authors of a paper he references call for a fundamental reconsideration of the current climate change paradigm, suggesting that cosmic rays and cloud physics are the real drivers of climate on multi-decadal time scales. Andrews emphasizes that there is strong evidence from various sources supporting this perspective, and that the carbon dioxide climate change narrative lacks such evidence. He also mentions other researchers, such as Tom Schuler and William Happer, who have presented evidence challenging the carbon dioxide climate change narrative. Andrews concludes by expressing his hope that this information is enlightening and encouraging, but does not offer predictions for future cooling and warming periods.
• 00:40:00 In this section of the YouTube video titled "Stephen Andrews: Importance of cosmic rays/clouds in recent warming | Tom Nelson Pod #253," Stephen Andrews discusses the role of cosmic rays in climate change and temperature fluctuations. He emphasizes that it is a multifactorial situation and making predictions is difficult. Andrews mentions the Winter Gatekeeper Theory, the Iris Effect, and geothermal activity as potential contributing factors. He believes that cosmic rays have a significant correlation with climate changes, as indicated by research. Andrews encourages critical thinking and data analysis, emphasizing the importance of accountability in scientific hypotheses.
