Temperature Changes Over the Past 50 Years: A Visual Tour Country by Country
Three years have come down to this article. I now feel that I have a good grasp on the spatial and temporal changes in temperature over the past 50 years. I feel like I have now achieved one of my goals in doing this work.
How To Achieve Better Data Comprehension, Part 3
It has taken me eight months to finish this series on achieving data comprehension. This is the third and final installment that explains how I have learned to be a data exploiter. You will need to read the article to find out what that means.
Do You Live In An Area Impacted By Global Warming?
This is a fun article. I created a Tableau dashboard that allows us to view 55 years of temperature data to see if global warming is impacting where we live. When you spend a little time using this tool, you will have a better appreciation of the variability of weather and the difficulty of concluding anything about global warming.
Visualizing Warming and Cooling Patterns in North America, Compliments of #Alteryx and #Tableau
I take a detailed look at maximum air temperature changes over North America. I wanted to see what has happened over my lifetime, or over the past 5 decades. The results are very interesting, at least to me.
Visualizing Observed Worldwide Air Temperature Changes
The more I work with this data set, the more I want to know about how our climate is changing. There are so many questions I have and in this article, I have been able to answer a few of them.
Uncovering Surprising Global Temperature Changes Via #Alteryx and #Tableau
I had an idea about global climate changes that I wanted to investigate. When the analysis was finished, the results surprised me and have helped me begin to understand the air temperature changes that are occurring around the world.
How to Use and Better Understand Alteryx Batch Macros
